ABSTRACT Overfishing, industrial fishing and climate change generate impacts that affect the marine fishery resource, the main source of income and food for coastal populations of artisanal fishers. The creation of conditions that increase the adaptive capacity of fishers will decrease their vulnerability to impacts. This research proposes to determine an Exclusive Zone for Artisanal Fishing-ZEPA as a strategy for sustainable management of fishery resources and climate adaptation for artisanal fishers in the study area. Marxan was used to identify three scenarios for the location of the ZEPA and participatory mapping was carried out with fishers to obtain the fourth scenario. High similarity was found between scenarios 2 and 4, which shows that the scientific (Marxan) and participatory (population) approaches coincide in the location of the ZEPA. The final ZEPA was located in the coastal marine zone of the municipalities of Tumaco and Francisco Pizarro, with a total area of 2,008 km2. Included important conservation targets for artisanal fisheries such as artisanal fishing grounds, ecosystems (mangroves, beaches and estuaries), areas of occurrence of species (seerfish, snappers, sea bass, piangua, marmoset shrimp) among others. More than 80 % of the fishers agreed that the strategy would help reduce their vulnerability to threats such as climatic phenomena, overfishing, pollution, among others. The contribution to climate change adaptation of the study area’s population is highlighted.

RESUMEN La sobrepesca, la pesca industrial y el cambio climático generan impactos que afectan al recurso pesquero marino, la principal fuente de ingreso y alimento de las poblaciones costeras de pescadores artesanales. La creación de condiciones que incrementen la capacidad de adaptación de los pescadores disminuirá su vulnerabilidad a los impactos. Esta investigación propone determinar una Zona Exclusiva de Pesca Artesanal-ZEPA como estrategia de manejo sostenible de los recursos pesqueros y de adaptación climática para los pescadores artesanales del área de estudio. Se utilizó el programa Marxan para identificar tres escenarios para la ubicación de la ZEPA y se realizó una cartografía participativa con pescadores para obtener el cuarto escenario. Se encontró similitud alta entre el escenario 2 y 4, lo que muestra que el enfoque científico (Marxan) y participativo (población) coinciden en la ubicación de ZEPA. La ZEPA definitiva se ubicó en la zona marino costera de los municipios de Tumaco y Francisco Pizarro, con un área total de 2 008 km2. Incluyó objetos de conservación importantes para la pesca artesanal como caladeros de pesca artesanal, ecosistemas (manglares, playas y estuarios), áreas de ocurrencia de especies (sierra, pargos, corvina, piangua, camarón tití), entre otros. Se identificó que más de 80 % de los pescadores estuvo de acuerdo en que la estrategia le aportaría a reducir su vulnerabilidad frente a amenazas como fenómenos climáticos, sobrepesca, contaminación, entre otros. Se resalta la contribución a la adaptación al cambio climático de la población del área de estudio.

Abstract Introduction: The biological collections represent the foundation for the knowledge and management of the biodiversity of a region. However, regional collections focused on echinoderms are scarce in Mexico, particularly in the Central Mexican Pacific (CMP). The biological collection of the Laboratorio de Ecología Molecular, Microbiología y Taxonomía (LEMITAX) belongs to the Centro Universitario de Ciencias Biológicas y Agropecuarias of the Universidad de Guadalajara, Jalisco, Mexico and it aims to serve as a reference for the region’s marine biodiversity. Objective: To state the richness of echinoderms in the LEMITAX collection. Methods: The organisms deposited at the LEMITAX have been collected by SCUBA, free-diving, and bottom trawls with biological dredges in different areas of the Mexican Pacific. The specimens are wet-preserved (70 % ethanol; Asteroidea, Echinoidea, Holothuroidea, and Ophiuroidea) or dried (Asteroidea and Echinoidea). Results: The specimens are from the states of Sinaloa, Nayarit, Jalisco, and Colima, including two natural protected areas (NPAs), the Isabel Island National Park and the sanctuary of the Islands and Islets of Bahía de Chamela. The collection has 20 761 specimens of echinoderms distributed in 75 species (10 asteroids, 17 ophiuroids, 17 echinoids, and 31 holothuroids). The best-represented state is Jalisco (64 species), followed by Nayarit (31), Colima (20), and Sinaloa (11). Concerning the NPAs, Chamela is the best represented (60), followed by Isabel Island (22). Thirty-four new records are added; the largest contribution is for Chamela, with 14 new records, followed by the state of Jalisco (seven), Nayarit (four), Colima (three), and Isabel Island (three). For the CMP, the presence of Astropecten ornatissimus, Luidia phragma, Cucumaria crax, and Holothuria (Cystipus) casoae, is reported for the first time, updating the echinoderm richness to 197 species. The bathymetric distribution range of Ophiactis simplex, Ophiocomella alexandri, and Holothuria (Cystipus) casoae is extended, as well as the geographic range of Cucumaria crax. Conclusions: The biological collections deposited in the universities contribute substantially to the knowledge of biodiversity, as reflected in the LEMITAX collection, whose revision resulted in the updating of the echinoderm richness in the region.

ABSTRACT Mansonia Blanchard mosquitoes are aggressive and opportunistic, making it difficult for habitation in certain areas. However, there is no data regarding their rearing in laboratory in Brazil. Therefore, the aim of this study was to evaluate the effect of different diet composition on the development of Mansonia humeralis immatures. The plant Pistia stratiotes was used as a substrate for larval attachment, and fish food (Tetra Marine® Flakes) and baker's yeast (Saccharomyces cerevisiae) in various combinations were used as feed. Eggs and larvae were obtained from mosquitoes collected in the field using protected human catches, and the experiments were conducted in the laboratory (25-27°C and 70-80% relative humidity) with 200 larvae per container (n=15). Mortality rate, larval development time, pupation rate, emergence rate, and the number of eggs and larvae were recorded. Overall, a high mortality rate (0.5 – 0.7) was observed in the first 12 days of the experiment in all diets, up to 50% of adults emerged from the remaining larvae with a male to female ratio of 1.1 to 1.3. The use of yeast in combination with fish food resulted in lower mortality rate (0.52), a shorter larval development time (34 days), a higher pupation rate (0.21) and number of eggs (21 eggs) compared to the other diets. However, fertility was very low (1%) regardless of the diet used. The use of yeast is recommended as part of the diet offered to this mosquito species under the laboratory conditions used in our study. opportunistic areas However Brazil Therefore immatures attachment Tetra Marine Flakes bakers baker s Saccharomyces cerevisiae feed catches 2527°C 2527C C 25 27°C 27 7080% 7080 70 80% 80 70-80 humidity 20 n=15. n15 n n=15 . 15 (n=15) recorded Overall 0.5 05 0 5 (0. 0.7 07 7 1 diets 50 11 1. 13 3 1.3 0.52, 052 0.52 , 52 (0.52) 34 (3 days, days) 0.21 021 21 (0.21 (2 1% (1% 2527 2 27C 708 8 70-8 n1 n=1 (n=15 0.

ABSTRACT Promoting inclusive and effective governance in regional estuaries offers an encompassing challenge within the scope of Policy analysis and its interactions within socioecological research. The integrated approach for both theoretical elements has not easily been improved, despite the increase in analytical frameworks in this theme. The Paranaguá Bay Zone (PBZ) in the state of Paraná, Brazil, is composed of a few cities, several large, protected areas, and traditional communities. On the one hand, the intensification of real estate pressures in a low demographic region is creating a wave of value conversion regarding the trends of the coastal gentrification phenomenon, notwithstanding the lower degree of intensity when compared to other Brazilian estuaries. On the other hand, it shows a lack of political representation and institutional action at the subnational level. This asymmetrical process is strongly related to historical land development and the controversial process of implementing protected areas and zoning tools. Promoting the economic rise of the territory has affected traditional communities and conservation management, requiring permanent improvement in the ability for community mobilization and juridical vigilance in the face of impacts related to such pressure. In the meantime, scholars have considered knowledge building, which brings up assessment issues on how the decision-making process has been operated and what gaps and asymmetries can be revealed for further resilience analyses. This study is an effort to approach the performance of participative governance of the estuary and is restricted to a preliminary assessment of the participative management committees designed by legislation under area-based attributions. This study is not aimed at exploring the belief systems of different social groups/stakeholders. Results have a great emphasis on methodological building and testing, which revealed the importance of imposing an inventory and hierarchy model on the multiple committees of governance and their sectorization across adjacent areas. Results also underline variables of interest and pilot indicators in the subject under analysis. Preliminary results point to the need for overcoming methodological challenges, and findings that are useful as first evidence in the comprehension of the low performance by different committees, which often operate without any regular, systematic, integrated, transparent, legitimate, and permanent agenda of Policy activities for the PBZ fisheries territory. Qualitative data and institutional memoirs should be available and categorized in government programs, whereas research efforts that look to better recognize the idiosyncrasies of community realities under the pressures of non-transparent economic drivers are much needed. improved theme (PBZ Paraná Brazil cities large hand phenomenon level tools pressure meantime decisionmaking decision making analyses areabased area based attributions groupsstakeholders groups stakeholders groups/stakeholders testing challenges regular systematic transparent legitimate programs nontransparent non needed

Abstract Introduction: Until today, the fishing effort by foreign fleets in the Costa Rican Pacific has not been analyzed. Objective: To determine the spatial distribution of the fishing effort of those fleets, variables that shape that distribution, and if they interact with management figures and highly fragile ecosystems. Methods: Using fishing effort data from 2012 to 2020, obtained from Global Fishing Watch, an Index of Fishing Effort (IEP) was calculated to apply geospatial and multivariate statistics, as well as multiple regression models. A grid with 55 905 cells of 0.10 degrees was used to apply Hot Spot Analysis, and another grid with 24 176 cell-year-month analysis units of 0.25 degrees was used to apply a Linear Regression Model. Results: The data reveals the fishing activity of international fleets associated with four types of fishing gear, and a wide coverage of a high IEP by two fleets throughout the nine years analyzed. The IEP is primarily associated with location and varies by month and year. There is also relative evidence that its influenced by the concentration of oxygen and nitrates. Conclusions: International fleets come into direct conflict with officially defined zones for national fleets and disrespect protected oceanic areas and a declared non-fishing zone to protect marine resources in the Costa Rican Pacific. Their activities in the Dome may affect a national yellowfin tuna fishery.

Given a growing global population and shift to embrace the blue economy, a need for marine spatial planning (MSP) has emerged in South Africa to sustainably resolve the rising conflicts over the use of marine and seabed resources and services. A well-developed marine spatial plan yields numerous ecological, social and economic benefits. These are achieved through mediating between spatially conflicting economic drivers' interests (e.g. commercial fishing, tourism, mining), preventing their activities from compromising thresholds of an environment's sustainability. Within the MSP framework, high-resolution geospatial datasets are required to document and describe the seabed in the highest possible detail. At any scale, integrated analysis of seabed geomorphology and habitats is anticipated to greatly improve the understanding of ecosystem functioning from a multidisciplinary perspective, whilst improving MSP procedures and management of marine space. South Africa is the first of few African countries to have an approved and implemented MSP framework, but is still somewhat behind globally in implementing large-scale regional hydroacoustic surveys to cover the country's vast offshore territory. The deficiency of hydroacoustic surveys is perhaps due to a relative lack of funds and poor communication about the value of multibeam echo-sounder (MBES) derived data, whilst marine geoscience remains a scarce skill in the country. This review paper presents a geological perspective of MSP and explores (1) the value that seabed mapping offers MSP specifically and (2) the need to increase seabed mapping with MBES, using a recently initiated project from the South African east coast as a case study. SIGNIFICANCE: The collected MBES data (our case study) provides unprecedented seabed detail of the complex reef habitat and adjacent areas within specific management zones of the uThukela Banks Marine Protected Area. We reveal seabed features and their spatial distribution at a scale not possible using earlier (singlebeam) seabed mapping techniques. These high-resolution data will enable a better understanding of east coast marine habitats whilst contributing to improved spatial management of areas within and around the uThukela Banks Marine Protected Area.

ABSTRACT The piramutaba, Brachyplatystoma vaillantii is a freshwater catfish that is the most abundant fishery resource in the Amazon estuary. Piramutaba trawling is done on industrial fishing scale and is characterized by the presence of many freshwater and marine bycatch species, with and without commercial value. Here we describe the bycatch of the industrial fishery of piramutaba in the Amazon estuary and evaluate the relationship of two important environmental factors, depth and salinity, with the accidental capture of freshwater and marine fishes in the Amazon estuary in the rainy and dry seasons. We identified 21 cartilaginous fish species (19.1% freshwater and 80.9% marine) and 125 bony fish species (25.6% freshwater and 74.4% marine). The bycatch included 64 species without commercial value (43% of all bycatch species), which are always discarded. Freshwater and estuarine fishes exhibited significantly higher abundances in shallower environments, while marine fishes were similarly abundant along the entire depth gradient. On the contrary, the abundance of freshwater fishes significantly decreased, and that of estuarine and marine fishes significantly increased with increasing salinity. Regarding the conservation status of the bycatch species, one is classified as vulnerable (VU), and seven as critically endangered (CR). The information on the bycatch of piramutaba fishery in the Amazon estuary is important to subsidize regional fisheries policies and the management of protected areas. factors salinity seasons 2 19.1% 191 19 1 (19.1 809 80 9 80.9 12 25.6% 256 25 6 (25.6 744 74 4 74.4 marine. . 43% 43 (43 , species) discarded environments gradient contrary decreased VU, VU (VU) CR.

RESUMO A piramutaba, Brachyplatystoma vaillantii é um bagre de água doce que representa o recurso pesqueiro mais abundante no estuário amazônico. O arrasto da piramutaba é feito em escala industrial, caracterizado pela presença de muitas espécies de água doce e marinha capturadas de forma incidental, com e sem valor comercial. Aqui descrevemos a captura incidental da pesca industrial de piramutaba no estuário amazônico e avaliamos a relação de dois fatores ambientais, profundidade e salinidade, com a captura incidental de espécies de água doce e marinhas nas estações chuvosa e seca. Identificamos 21 espécies de peixes cartilaginosos (19,1% de água doce e 80,9% marinhos) e 125 espécies de peixes ósseos (25,6% de água doce e 74,4% marinhos). A captura incidental incluiu 64 espécies sem valor comercial (43% de todas as espécies capturadas) que sempre são descartadas. Os peixes de água doce e estuarinos exibiram abundâncias significativamente maiores em ambientes mais rasos, enquanto os peixes marinhos foram igualmente abundantes ao longo de todo o gradiente de profundidade. Inversamente, a abundância de peixes de água doce diminuiu significativamente, e a de peixes estuarinos e marinhos aumentou significativamente em salinidades maiores. Em relação ao estado de conservação das espécies capturadas, uma é reconhecida como vulnerável (VU) e sete como criticamente ameaçadas (CR). As informações sobre a captura incidental da pesca da piramutaba no estuário amazônico são fundaentais para subsidiar políticas pesqueiras regionais e gestão de áreas protegidas. ambientais salinidade seca 2 19,1% 191 19 1 (19,1 809 80 9 80,9 12 25,6% 256 25 6 (25,6 744 74 4 74,4 marinhos. . 43% 43 (43 descartadas rasos Inversamente VU (VU CR.

Resumen Se evaluó el estado de los recursos hidrobiológicos (RHB) de tres Áreas Marinas Protegidas (AMPs) del Pacífico de Colombia: Parque Nacional Natural (PNN) Utría, PNN Uramba Bahía Málaga y PNN Sanquianga. Para el análisis se utilizaron cuatro indicadores pesqueros: 1) Abundancia relativa dada como el desembarco por unidad de esfuerzo (DPUE); 2) Esfuerzo (h); 3) Talla (cm); y 4) Porcentaje de individuos capturados por debajo de la talla media de madurez sexual (TMM). Los indicadores de DPUE y esfuerzo, obtuvieron calificaciones bajas de acuerdo con las categorías construidas por Herrera (2020), a excepción del PNN Utría. Con respecto a los indicadores “tallas” y “porcentaje de individuos capturados por debajo de la TMM”, estos presentaron calificaciones bajas, y están estrechamente relacionados con las reducidas tallas de captura en las áreas. Dadas las evidencias de que los recursos en las AMPs están en una condición que no es sostenible (PNN Uramba Bahía Málaga y PNN Sanquianga), es necesario avanzar en el establecimiento de medidas de manejo (tallas mínimas de captura, vedas temporales y espaciales, control de selectividad de artes de pesca), que resulten en la reducción del esfuerzo por pesca y el aumento de capturas por encima de la TMM de las especies.

Abstract The state of the hydrobiological resources (HBR) of three Marine Protected Areas (MPAs) of the Colombian Pacific was evaluated: Utría National Natural Park (NNP), Uramba Bahía Málaga NNP and Sanquianga NNP. Four fishery indicators were used for the analysis: 1) relative abundance given as landing per Unit Effort (LPUE); 2) effort (h); 3) size (cm); and 4) percentage of individuals captured below the average size at sexual maturity (ASM). The LPUE and effort indicators obtained low ratings in the MPAs according the categories constructed in Herrera (2020), with the exception of PNN Utría. Regarding the indicators "sizes" and "percentage of individuals captured below the ASM, these presented low scores, and are closely related to the reduced sizes of capture in the areas. Given the evidence that the resources in the MPAs are in a condition that is not sustainable (PNN Uramba Bahía Málaga and PNN Sanquianga), it is necessary to advance in the establishment of management measures (minimum catch sizes, time and space closures, selectivity control of fishing gear), which result in the reduction of fishing effort and the increase of catches above the TMM of the species.

Abstract The conservation of Protected Areas (PAs) in the Galapagos Islands has reached several acknowledgments: Natural Heritage of Humanity, Biosphere Reserve, Marine Sanctuary, Ramsar Site, etc. One of the reasons to achieve this recognition is the availability of scientific knowledge generated by important institutions such as the Charles Darwin Foundation (CDF). This knowledge helps to provide the local environmental authority (GNPD, Galapagos National Park Directorate) with scientific evidence for decision-making. Nonetheless, there is the challenge of offering greater accessibility to information and evaluating the advances toward the Sustainability Development Objectives (SDOs). At the same time and according to current trends, scientific research which is based on collaborative, providing transparency of all the phases included in research builds the concept of open science, demonstrating the main idea behind information management. This article intends to present the first steps to open science that our institution is working on. We present a CDF projects visualizer and the provision of a geoportal with data from the Plan Galapagos 2030 in collaboration with the Government Council of the Galapagos Special Regime. Secondly, we will develop an assessment of the impact of the opening of these datasets and its visualizers. That is to say, we will analyze the qualities and observations perceived by the community, regarding the disposition of the published visualizer and geoportal; which will also allow for the identification of identifying the main challenges and uncertainties towards the growth and implementation of open science for CDF's scientific production.

Resumen La conservación de las AAPP del Archipiélago de Galápagos ha alcanzado un sinnúmero de reconocimientos: Patrimonio Natural de la Humanidad, Reserva de la Biosfera, Santuario Marino, Sitio Ramsar, etc. Esto gracias a, entre otras actividades, al conocimiento técnico/científico generado a partir de instituciones como la Fundación Charles Darwin (FCD). Este conocimiento provee a la autoridad ambiental local (DPNG, Dirección del Parque Nacional Galápagos) de evidencia científica para la toma de decisiones en el manejo de la Reserva Marina y del Parque Nacional. De acuerdo a las tendencias actuales, existe el reto de tener una mayor accesibilidad a la información, específicamente a la investigación científica de la FCD. El concepto de ciencia abierta que se pretende implementar se basa en el trabajo colaborativo y datos FAIR, siendo este el ideal de hacia donde la gestión de la información apunta. Este artículo pretende presentar los inicios hacia la ciencia abierta por parte de la FCD. Un visualizador de los proyectos científicos institucionales y un geoportal de datos sobre el Plan de Desarrollo Sustentable y Ordenamiento Territorial del Régimen Especial de Galápagos (Plan Galápagos 2030); han sido los primeros pasos concretos para poner a disposición el libre acceso a la información. En segundo lugar, se realizará una evaluación del impacto de la apertura de esta información: es decir se analizarán las percepciones de los visualizadores publicados; lo que permitirá identificar los retos hacia la implantación de la ciencia abierta para la producción científica de la FCD.

Abstract Environments contaminated with metals can induce accumulation of trace metals in soft tissues of marine fauna resulting in negative effects. The oral brooding sea star Anasterias minuta is one of the most con spicuous macro-invertebrate top-predator species in the Atlantic Patagonian rocky shores that could accumulate trace elements and be used as biomonitor of coastal metal pollution. The aim of this study was to quantify metals concentrations on gonads of A. minuta populations in an anthropogenic impacted and in a natural protected area. Sea stars A. minuta were collected from two rocky intertidal populations in San Matías Gulf, near an iron-ore loading wharf at Punta Colorada (PC), and in the Natural Protected Area Puerto Lobos (PL), located 35 km south to PC. The essential metals Fe, Mn, Zn, Cu, Cr and Ni, and the non-essential metal Cd and As were present in gonads of A. minuta from both populations. However, the essential metal Co and the non-essential metal Pb were only detected in the Natural Protected Area PL, with values below to quantification limit at PC. As high metal concentrations can impact negatively on sea star populations and shore habitats, this metal survey obtained from gonads of A. minuta populations could be useful as a reference to start a monitoring program in urbanized and marine protected areas.

Resumen Los ambientes contaminados con metales pueden inducir a la acumu lación de metales trazas en los tejidos blandos de la fauna marina, resultando en efectos negativos. La estrella de mar incubadora Anasterias minuta es una de las especies de depredadores superiores de macroinvertebrados más conspicuas en las costas rocosas de la Patagonia Atlántica que podría acumular elementos traza y usarse como biomonitor de la contaminación costera por metales. El objetivo de este estudio exploratorio fue cuantificar las concentraciones de metales en las gónadas de poblaciones de A. minuta en un área con impacto antrópico y en un Área Natural Protegida. Las estrellas de mar A. minuta fueron recolectadas de dos poblaciones intermareales rocosas del Golfo San Matías, cerca de un muelle de carga de mineral de hierro en Punta Colorada (PC), y en el Área Natural Protegida Puerto Lobos (PL), ubicada 35 km al sur de PC. Los metales esenciales Fe, Mn, Zn, Cu, Cr y Ni, y los metales no esenciales Cd y As estuvieron presentes en las gónadas de ambas poblaciones de A. minuta. Sin embargo, el metal esencial Co y el metal no esencial Pb fueron solo detectados en el Área Natural Protegida PL, con valores inferiores al límite de cuantificación en PC. Dado que las altas concentraciones de metales pueden tener un impacto negativo en las poblaciones de estrellas de mar y los hábitats costeros, estos datos de metales obtenidos de las gónadas de las poblaciones de A. minuta podrían ser útiles como referencia para comenzar un programa de monitoreo en áreas urbanizadas y marinas protegidas.

Abstract The Eastern Tropical Pacific (ETP) is characterized by complex oceanographic dynamics that affect the regional sea surface temperature (SST), a key parameter driving marine ecosystems. To date no comparative studies have been conducted on the spatial and temporal variations of SST among the several marine protected areas in the ETP. The present study used remote sensing to evaluate the monthly, annual, and decadal variations in SST from 1982 to 2019 in Coiba National Park (Coiba), Cocos Island National Park (Cocos), Malpelo Fauna and Flora Sanctuary (Malpelo), Gorgona Island National Park (Gorgona), Galápagos Marine Reserve (Galápagos) and La Plata Island (La Plata). An overall increasing trend in SST was observed across all study sites, except for West Galápagos. A decrease in SST anomaly was observed from February through April at Malpelo, Coiba, Gorgona and La Plata. These observations are likely in response to the Humboldt Current and upwelling events in the Colombian Pacific Basin. Using a longer SST dataset is recommended to determine if the annual, monthly and decadal trends observed here are driven by local, regional or global processes. Consistent monitoring of SST trends is a strategic practice in understanding and planning for current and projected changes in the marine environment.

Resumen El Pacífico Oriental Tropical (POT) se caracteriza por presentar una dinámica oceanográfica compleja que afecta la temperatura superficial del mar (TSM), un parámetro clave que influye los ecosistemas marinos. Hasta la fecha no se han realizado estudios comparativos de las variaciones espaciotemporales de la TSM entre las distintas áreas marinas protegidas en el POT. Esta investigación utilizó sensores remotos para evaluar las variaciones mensuales, anuales y decadales de la TSM desde 1982 a 2019 en el Parque Nacional Coiba (Coiba), Parque Nacional Isla del Coco (Coco), Santuario de Fauna y Flora Isla Malpelo (Malpelo), Parque Nacional Natural Isla Gorgona (Gorgona), Reserva Marina de Galápagos (Galápagos) e Isla de La Plata (La Plata). Se observó una tendencia creciente en la TSM en la mayoría de los sitios estudiados, excepto en el oeste de Galápagos. Se registró una disminución en la anomalía de la TSM durante los meses de febrero a abril en Malpelo, Coiba, Gorgona y La Plata. Las diferencias observadas son probablemente en respuesta a la corriente de Humboldt y eventos de afloramiento en la cuenca del Pacífico colombiano. Se recomienda emplear series de tiempo de mayor resolución temporal para determinar si las tendencias anuales, mensuales y decadales observadas en este estudio responden a cambios locales, regionales o globales. El monitoreo constante de las tendencias en la TSM es una práctica estratégica para comprender y planificar los cambios actuales y proyectados en el ambiente marino.

Abstract This study evaluated the effectiveness of Federal Protected Areas on the coast of the state of Paraíba in northeastern Brazil with regard to the preservation of mangrove forests. The study area encompassed remaining mangrove forests distributed in four federal protected areas (PAs) located in Paraíba: Area of Relevant Ecological Interest (AREI) of Mangroves of the Mamanguape River, Environmental Protection Area (EPA) of the Mamanguape River, the Restinga de Cabedelo National Forest (NATFOR), and the Acaú-Goiana Extractive Reserve (EXTRES). The methods consisted of a spatiotemporal analysis considering the year of creation of each PA, with mapping and quantification as well as the assessment of impacts and effectiveness. NATFOR and EXTRES had the most conserved mangrove areas on the temporal scale, whereas AREI and EPA had the largest reductions in areas of mangrove forest. Urban expansion, sugarcane monoculture, and shrimp farming represented the main negative impacts spatially identified in these PAs. Based on the results of this study, the mangrove forests analyzed have continually suffered anthropogenic pressures since their creation as protected areas. The greatest effectiveness in the preservation of mangrove forests was found in Acaú-Goiana EXTRES and the least effectiveness was found in the AREI of Mangroves of the Mamanguape River.

Abstract This study identified the marine protected areas (MPAs) affected by the most extensive oil spill recorded on the Southwestern Atlantic coast, Brazil (2019/2020). We found that 81 MPAs suffered the direct or indirect effects of spilled oil, producing chemical, biological and socioenvironmental impacts over approximately 3.0% of the 2,659 protected areas currently established in Brazil. Although estimates suggest a moderate volume of spilled oil, the incident reached wide coastal strips, probably producing more damage to MPAs than other cases worldwide. Further, the generated negative impacts affected the already fragile environmental protection system in Brazil, potentially leading to negative impacts on global networks of MPAs and worldwide biodiversity.

Abstract Microplastics are ubiquitous contaminants of marine ecosystems around the world and Antarctica is no exception. Microplastics can be influenced by sedimentary dynamics mainly on coastal areas where they are more abundant in Antarctica. This study evaluated microplastic contamination in beach environments from two Antarctic Specially Protected Areas, aiming to identify relationships between microplastic numbers and sedimentological parameters on beach sediments. Low numbers of microplastics were found (> 0.5 mm; fibers excluded) – one particle per sample in 4 of 15 samples analyzed – and there is no evidence of widespread contamination. Sedimentological parameters reveal differences between sampled environments, but low numbers of microplastics impaired statistical comparison. All sediment samples are coarse, denoting highenergy depositional environments that are likely little susceptible to microplastic accumulation. Microplastic contamination in the Antarctic coastal ecosystem is heterogeneous, and their detailed characterization assisted by a systematization of methods can improve the understanding of microplastics distribution patterns in the cold coastal ecosystem. exception Areas sediments > ( 05 0 5 0. mm excluded 1 comparison coarse accumulation heterogeneous

ABSTRACT The invasive and predatory lionfish (Pterois volitans/miles) has been caught and recorded in areas more than 100 km off the Yucatan coast, as far as Scorpion Reef (22°22´5” N, 89°40´57” W), in the Gulf of Mexico. On August 2020, fishermen from the Dzilam de Bravo community captured and recorded an adult lionfish 338 mm in length and 568 g in weight. This site consists of a marine bottom that is mainly rock formation, where different juvenile fish species gather. The diet is wide and voracious, hence lionfish present many threats to a variety of fry and juvenile fish species; fish that are of commercial fisheries interest. Consequently, the fishing community is concerned since the lionfish specimen was caught nearby known fishing areas. Its presence poses a threat to their livelihood and may affect the catch rate. Therefore, the present study aims to provide early warning signs that could encourage the corresponding authorities to monitor the lionfish population in this area and along the Yucatán coastline.

RESUMEN En el Golfo de México, particularmente en el Estado de Yucatán, se ha reportado la presencia y captura de pez león (Pterois volitans/miles) en zonas a más de 100 kilómetros de la costa como es Arrecife Alacranes (22°22´5” N, 89°40´57” W). En agosto de 2020, pescadores de la comunidad de Dzilam de Bravo capturaron un ejemplar adulto de pez león de 338 mm de longitud total y 568 gramos de peso a 22 kilómetros de la costa y 13.4 metros de profundidad. El paisaje marino en este sitio está conformado por formaciones rocosas en donde se agregan peces juveniles de diferentes especies. La voracidad y amplitud de dieta de este organismo presentan una potencial amenaza debido al consumo de alevines y juveniles de especies de importancia pesquera. Por tal motivo, la presencia de este organismo en una zona cercana a la costa causa inquietud entre los pescadores de la comunidad debido al posible efecto sobre las tasas de captura. El presente estudio pretende generar una alerta temprana e incentivar a las autoridades correspondientes a monitorear esta y otras zonas de la costa yucateca.
