ABSTRACT: The Cape Horn Biosphere Reserve (CHBR) is considered as a natural laboratory at the southern end of the sub-Antarctic Magellanic ecoregion. The retreat of glaciers present along the channels and fjords of the CHBR due to global climate change impacts the marine benthic and macroalgae communities hosted in these water bodies. Current knowledge about this subantarctic marine flora is scarce and its first reports date from the 18th and 19th centuries. To solve this knowledge gap, we created the Sub-Antarctic Cryptogamic Herbarium (SCH) thanks to the support of the Cape Horn International Center (CHIC) in the Antarctic and Sub-Antarctic Marine Ecosystems Laboratory (LEMAS), University of Magallanes. As such, the SCH's botanical collection is currently the only gateway to the subantarctic ecosystem's biological legacy. The catalogue below provides information about the ecological and morphological characteristics of macroalgae deposited in the SCH, with the particular focus on those species present in the CHBR. We identified 54 species, most notable of which the Rhodophyta macroalgae accounting for more than 40% of the total composition and a high species richness of algae with filamentous and/or tubular thallus, typical of hyposaline habitats. Additionally, Caleta Olla was significant for its presence of Devaleraeayagan, thereby increasing its distribution known until then, and for being the only site studied to include an exotic invasive species (Polysiphonia morrowii). Despite its geographical proximity with the Diego Ramírez Archipelago, the floristic affinity of macroalgae from the Beagle Channel is greater with that of species from well-protected habitats such as the fjords and channels of the northern part of the CHBR. In the context of the increasing environmental threats, the SCH is essential to evaluate changes in biodiversity and establish conservation measures for these vulnerable sub-Antarctic ecosystems.

RESUMEN: La Reserva de Biosfera de Cabo de Hornos (RBCH) es considerada como un laboratorio natural en el extremo austral de la ecorregión subantártica de Magallanes. Los glaciares presentes a lo largo de sus canales y fiordos están hoy retrocediendo por el cambio climático global, impactando a las comunidades marinas bentónicas, particularmente a las de macroalgas. El conocimiento actual sobre esta flora marina subantártica es aún escaso y sus primeros reportes datan de los siglos XVIII y XIX. Para resolver esta brecha de conocimiento, creamos el Herbario de Criptógamas Subantárticas (HCS) con apoyo del Cape Horn International Center (CHIC) en el Laboratorio de Ecosistemas Marinos Antárticos y Subantárticos (LEMAS), Universidad de Magallanes. El HCS es el repositorio criptogámico más austral del mundo y el único portal actual del patrimonio biológico subantártico. Este catálogo da a conocer las características ecológicas y morfológicas de las macroalgas en ambientes glaciares del Canal Beagle en la RBCH y depositadas en el HCS. Se identificaron 54 especies de macroalgas, destacándose la presencia de algas Rhodophyta que representan más del 40% de la composición total y una alta riqueza de algas con talos filamentosos y/o tubulares, típica de hábitats hiposalinos. Adicionalmente, Caleta Olla se destacó por la presencia de Devaleraea yagan, aumentando su distribución hasta ahora conocida, y por ser el único sitio muestreado en contar una especie exótica invasora (Polysiphonia morrowii). A pesar de su proximidad con el Archipiélago Diego Ramírez la afinidad florística de las macroalgas del Canal Beagle es mayor con especies de hábitats protegidos, como los fiordos y canales que se encuentran al norte de la RBCH. Ante las crecientes amenazas ambientales, el HCS es esencial para evaluar cambios en la biodiversidad subantártica y establecer medidas de conservación para ecosistemas vulnerables.

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.

Resumo Neste artigo apresentamos resultados de uma pesquisa que integra o projeto internacional “Gender and COVID-19”, que contempla diversos temas relacionados aos impactos da pandemia na vida de mulheres e suas famílias, entre eles a insegurança alimentar e a fome. Foram feitas entrevistas semiestruturadas entre dezembro de 2020 e novembro de 2021 com 49 mulheres, moradoras de dois aglomerados urbanos, Cabana do Pai Tomás (Belo Horizonte, MG) e Sapopemba (São Paulo, SP), e de duas comunidades rurais quilombolas, Córrego do Rocha (Chapada do Norte, MG) e Córrego do Narciso (Araçuaí, MG). As análises foram baseadas nas seguintes categorias: sentimentos e termos relacionados à fome; redução na quantidade e qualidade de alimentos; ausência de alimento e nutrientes; dificuldades para produzir alimento, receber auxílio emergencial e/ou doação de alimentos; avaliação dos governos e redes de apoio. Os relatos das entrevistadas evidenciam os desafios vivenciados, suas formas de enfrentamento e críticas à falta de respostas dos governos. Além de apresentarem uma perspectiva de gênero, as mulheres, em especial as lideranças que atuaram na construção de redes de solidariedade, são vozes fundamentais no planejamento de ações de prevenção e mitigação dos impactos de situações emergenciais em suas comunidades.

Abstract This paper presents the results of the research nested in the international project “Gender and COVID-19”, which includes several topics related to the impact of the pandemic on the lives of women and their families, including food insecurity and hunger. Semi-structured interviews were conducted from December 2020 to November 2021 with 49 women living in two urban conglomerates, Cabana do Pai Tomás (Belo Horizonte, MG) and Sapopemba (São Paulo, SP), and two rural quilombola communities, Córrego do Rocha (Chapada do Norte, MG) and Córrego do Narciso (Araçuaí, MG). The analyses were based on the following categories: hunger-related feelings and terms; reduced food amount and quality; lack of food and nutrients; difficulties producing food, receiving emergency aid or food donations; governments evaluation and support networks. The respondents’ reports show the challenges they experienced, their coping methods, and criticism of the government’s lack of responses. Besides presenting a gender perspective, women, especially the leaders who worked in the construction of solidarity networks, are fundamental voices in planning actions to prevent and mitigate the impacts of emergencies in their communities.

RESUMEN En la ecorregión Chaco Seco, caracterizada por bosques xerófilos, estacionales y abiertos, las plantaciones forestales monoespecíficas generan un fuerte impacto sobre la biodiversidad del ecosistema. Es esperable que estos efectos sean menores si se utilizan especies nativas de la región. El objetivo del trabajo fue comparar el efecto de bosques implantados de Prosopis alba y Eucalyptus tereticornis sobre la diversidad de artrópodos epígeos en la ecorregión Chaco Seco. En la Estación Experimental Fernández de la Universidad Católica de Santiago del Estero se seleccionaron tres rodales experimentales de E. tereticornis y tres de P. alba, además de tres sectores de bosque sin intervenir durante 50 años, como referencia. En otoño y primavera, bajo la copa de 12 árboles por sitio, fueron colocadas trampas de caída durante 24 h. A partir de las capturas se calcularon índices de diversidad. En otoño no se observaron diferencias entre sitios. Sin embargo, en primavera, P. alba mostró la mayor diversidad de artrópodos terrestres, en comparación con E. tereticornis y el sitio sin intervención. Los resultados podrían estar relacionados a la calidad y/o cantidad de residuos vegetales que se acumulan en los distintos rodales así como también a la flora que se desarrolla en cada sitio, siendo más favorable el aporte de P. alba a la biodiversidad. Estos resultados indicarían que el bosque cultivado de P. alba es más favorable para la conservación de la biodiversidad que los bosques de especies foráneas en la ecorregión Chaco Seco.

ABSTRACT In the Dry Chaco ecoregion, characterized by the presence of open and seasonal xerophytic forest, monospecific plantations generate a strong impact on the ecosystem’s biodiversity. It is expected that these effects will be less significant if native species of the region are used. In this sense, the objective of this work was to compare the effect of implanted forests of Prosopis alba and Eucalyptus tereticornis on the diversity of epigeal arthropods in the Dry Chaco ecoregion. In the Fernández Experimental Station of the Catholic University of Santiago del Estero, three forests of E. tereticornis and three of P. alba were selected, adding as a reference three sectors of forest without intervention for 50 years. In autumn and spring, under the canopy of 12 trees per site, pitfall traps were placed for 24 h. Then diversity indexes were calculated. In autumn there were no differences between sites. However, in spring, the P. alba forest showed the highest diversity of terrestrial arthropods, compared to E. tereticornis and the site without intervention. These results could be related to the quality and/or quantity of the understory that accumulate in the different forests, as well as to the flora that develops in each site, being P. Alba contribution more favorable to biodiversity. In this regard, cultivated forests of P. alba favors the conservation of biodiversity more than forests of foreign species in the Chaco Seco ecoregion.

RESUMO O Brasil se destaca no cenário internacional em relação a produção de celulose de fibra curta. Apesar da grande biodiversidade brasileira, essa produção está baseada em clones de espécies exóticas de Eucalyptus. Nesse contexto, pode haver grande potencial na avaliação de novas fontes de fibras da flora brasileira, incluindo a região amazônica. O presente estudo teve como objetivo avaliar o potencial tecnológico da madeira de Ochroma pyramidale (Malvaceae) para produção de celulose kraft. Indivíduos de quatro anos de idade foram colhidos em um plantio comercial para produção de serrados no Estado do Mato Grosso. Determinamos as propriedades químicas (teores de holocelulose, lignina Klason, lignina solúvel, extrativos e cinzas), físicas (massa específica e porosidade) e morfologia de fibras (comprimento e largura de fibras, diâmetro do lume, espessura e fração de parede, coeficiente de flexibilidade, índice de enfeltramento e de Runkel) da madeira. Na polpação kraft a carga alcalina aplicada variou entre 10 e 24%, com intervalo de 2%. A madeira de Ochroma pyramidale apresentou características favoráveis à produção de polpa celulósica, como dimensões apropriadas das fibras e baixos teores de lignina, extrativos e cinzas. Os teores de álcali ativo residual e pH do licor negro apresentaram relação crescente com a carga alcalina aplicada nos processos de polpação. O acréscimo da carga alcalina reduziu o rendimento em polpação, número kappa, teor de rejeitos e aumentou o teor de ácidos hexenurônicos.

ABSTRACT Brazil stands out in the international scenario in the production of short-fiber pulp. Despite the great Brazilian biodiversity, that production is based on exotic Eucalyptus clones. In this sense, there may be great potential in the assessment of new sources of fibers from the Brazilian flora, including the Amazon. The present study aimed to assess the technical potential of the wood of Ochroma pyramidale (Malvaceae) for the production of kraft pulp. Four-year-old trees were harvested from a commercial forest for lumber production in Mato Grosso state (Brazil). We determined the wood’s chemical compositions (holocellulose, Klason lignin, soluble lignin, extractives and ash contents), physical properties (density and porosity), and fiber morphology (fiber length, width and thickness, lumen diameter, wall fraction, coefficient of flexibility, and slenderness and Runkel ratios). The wood was subjected to pulping with an effective alkali charge ranging from 10 to 24%, with intervals of 2%. Ochroma pyramidale wood presented characteristics favorable to the production of cellulosic pulp, such as appropriate fiber dimensions and low lignin, extractives, and ash content. The amount of residual active alkali and pH of the black liquor were positively related to the increase of the alkali charge employed in the pulping process. The increase of alkali charge decreased the pulp yield, kappa number and waste content, and increased the hexenuronic acid concentration.

Objective: To describe and compare measures of maternal depression, anxiety, and posttraumatic stress symptoms before and during the coronavirus disease 2019 (COVID-19) pandemic in a Brazilian birth cohort. Methods: All hospital births occurring in the municipality of Rio Grande (southern Brazil) during 2019 were identified. Mothers were invited to complete a standardized questionnaire on sociodemographic and health-related characteristics. Between May and July 2020, we tried to contact all cohort mothers of singletons, living in urban areas, to answer a standardized web-based questionnaire. They completed the Edinburgh Postnatal Depression Scale (EPDS) and Generalized Anxiety Disorder 7-item (GAD-7) in both follow-ups, and the Impact of Event Scale (IES) in the online follow-up. Results: We located 1,136 eligible mothers (n=2,051). Of those, 40.5% had moderate to severe stress due to the current pandemic, 29.3% had depression, and 25.9% had GAD. Mothers reporting loss of income during the pandemic (57.2%) had the highest proportions of mental health problems. Compared to baseline, the prevalence of depression increased 5.7 fold and that of anxiety increased 2.4-fold during the pandemic (both p < 0.001). Conclusion: We found a high prevalence of personal distress due to the ongoing COVID-19 pandemic, and a clear rise in both maternal depression and anxiety.

RESUMEN Las raíces de Rhizophora mangle proveen un hábitat de guardería para muchas especies debido a la estructura tridimensional que forman, lo cual delimita un área de difícil acceso para depredadores grandes. Adicionalmente, proveen un sustrato duro para muchas especies bentónicas, que se atan a las raíces y contribuyen a la estructura tridimensional del ecosistema. Entre esos organismos, encontramos varias macroalgas, que contribuyen a la productividad primaria del ecosistema y proveen alimento y refugio a los herbívoros. En el presente estudio se identificaron las macroalgas asociadas a las raíces de Rhizophora mangle, en playa Cholón, en las islas del Rosario, Caribe colombiano. Se reportan 36 especies of macroalgas: 21 Rhodophyta, once Chlorophyta y cuatro Phaeophyceae. De esas 36 especies, 19 son nuevos registros para las islas, y otros seis son nuevos registros para Colombia. Este es el primer estudio sobre las macroalgas asociadas a las raíces de manglar en el Caribe colombiano, e ilustra tanto la alta diversidad de la flora marina en el Caribe suroccidental, como la falta de estudios sobre el tema.

ABSTRACT The roots of the red mangrove, Rhizophora mangle, provide a nursery habitat for many species, due to the tridimensional structure they provide, which delimits an area difficult to access to large predators. Moreover, they provide a hard substrate for many benthonic species, which attach to the roots and contribute to the tridimensional structure of the ecosystem. Among these organisms, there are several macroalgae, which contribute to the primary productivity of the ecosystem and provide food and shelter to herbivores. In the present study we identified the macroalgae associated with the roots of Rhizophora mangle, in Cholón beach, Rosario Islands National Park, Caribbean Colombia. We report a total of 36 species of macroalgae: 21 Rhodophyta, eleven Chlorophyta, and four Phaeophyceae. Of these, 19 are new records for the islands, and six are new records for Colombia. This is the first study on the macroalgae associated with mangrove roots in the Colombian Caribbean, and it highlights both the high diversity of the marine flora of the Southwestern Caribbean, as well as the paucity of studies on the topic.

RESUMEN Con el objetivo de determinar tendencias en la abundancia relativa a través del tiempo para especies priorizadas dentro del Plan de Manejo del Santuario de Fauna y Flora Malpelo, se realizaron censos visuales submarinos (CVS) entre abril de 2009 y agosto de 2019. Se colectaron datos para cinco especies de peces óseos: jurel azul (Caranx melampygus), bravo (Seriola rivoliana), atún aletiamarillo (Thunnus albacares), cherna (Dermatolepis dermatolepis) y mero (Mycteroperca olfax), y seis especies de peces cartilaginosos: raya águila (Aetobatus laticeps), tiburón sedoso (Carcharhinus falciformis), tiburón de Galápagos (Carcharhinus galapagensis), tiburón aletiblanco de arrecife (Triaenodon obesus), tiburón ballena (Rhincodon typus) y tiburón martillo (Sphyrna lewini). En términos generales, se observó una tendencia negativa no significativa en la abundancia relativa a través del tiempo para la mayoría de las especies evaluadas, exceptuando A. laticeps y T. obesus, las cuales mostraron tendencias positivas no significativas. El tiburón martillo (S. lewini) fue la única especie que mostró una disminución estadísticamente significativa de su abundancia a través del tiempo. Los resultados de este estudio evidencian la necesidad apremiante de establecer medidas más eficientes de manejo y de regulación pesquera, que promuevan la conservación de especies importantes de peces no sólo dentro del santuario sino a lo largo del Pacífico Oriental Tropical.

ABSTRACT To determine trends over time in the relative abundance of species prioritized in the Malpelo Fauna and Flroa Sanctuary Management Plan, underwater visual censuses were done from April 2009 to August 2019. Data were collected for five species of bonefish: bluefin trevally (Caranx melampygus), longfin yellowtail (Seriola rivoliana), yellowfin tuna (Thunnus albacares), leather bass (Dermatolepis dermatolepis) and sailfin grouper (Mycteroperca olfax), and six cartilaginous fish: spotted eagle ray (Aetobatus laticeps), silky shark (Carcharhinus falciformis), Galapagos shark (Carcharhinus galapagensis), whitetip reef shark (Triaenodon obesus), whale shark (Rhincodon typus) and scalloped hammerhead shark (Sphyrna lewini). A negative non-significant trend in abundance through time was observed for most of the evaluated species, except A. laticeps and T. obesus, which showed positive non-significant trends. The hammerhead shark (S. lewini) was the only species that showed a statistically significant decrease in abundance over time. The results of this study highlight the urgent need to establish more effective fisheries management and regulation measures that promote the conservation of important fish species, not just inside the sanctuary but also within the Tropical Eastern Pacific.

Resumen: Antecedentes y Objetivos: En la última década, la investigación ficológica en la Reserva Internacional de Biosfera Seaflower ha revelado una diversidad en su flora marina que no había sido previamente apreciada. Este trabajo tiene como objetivo contribuir al conocimiento de la biodiversidad macroalgal del Archipiélago de San Andrés, Providencia y Santa Catalina en el Caribe Colombiano, adicionando 11 nuevos registros de algas rojas. Métodos: Las algas fueron recolectadas alrededor de las islas en 10 puntos, cubriendo diferentes ecosistemas, por medio de buceo SCUBA a profundidades entre 0 y 37 m. El muestreo se realizó entre agosto y noviembre de 2009, diciembre de 2012 y septiembre de 2019 durante la Expedición Científica Seaflower. Las algas recolectadas se conservaron en una solución de formalina/agua de mar al 4%. La identificación se realizó mediante microscopio óptico y literatura especializada. Todos los especímenes fueron depositados en el herbario JIW del Departamento de Biología de la Universidad Nacional de Colombia, en Bogotá, Colombia. Resultados clave: Se presentan 11 nuevos registros de especies de macroalgas rojas para la Reserva Internacional de la Biosfera Seaflower en el Mar Caribe. Seis taxa fueron previamente citados para el Caribe colombiano: Botryocladia spinulifera, Champia taironensis, Dasya caraibica, Pterocladiella bartlettii, Seirospora occidentalis y Spyridia aculeata subsp. complanata. Las restantes cinco especies son nuevos registros para el país: Botryocladia cf. bahamensis, Botryocladia cf. bermudana, Ceramium brevizonatum var. caraibicum, Gloioderma iyoense y Wrightiella tumanowiczii. Con estos resultados la Reserva Internacional de Biosfera Seaflower presenta un total de 153 especies de rodófitas, pertenecientes a 12 órdenes, 27 familias y 73 géneros. Conclusiones: Con las investigaciones realizadas en los últimos 10 años, el número de taxones registrados ha aumentado de 202 a 325, lo que representa un aumento de 62% en el conocimiento de la diversidad macroalgal y ubica al Archipiélago en la segunda región más diversa del Caribe colombiano.

Abstract: Background and Aims: During the past decade, phycological research in the Seaflower International Biosphere Reserve has revealed a much more diverse marine flora than historically appreciated. This work aims to contribute to the knowledge of macroalgal biodiversity in the Archipelago of San Andres, Old Providence and Saint Cataline, Colombian Caribbean, adding 11 new records of red algae. Methods: The samples were collected around the islands in ten points covering different ecosystems, by SCUBA diving at depths between 0 and 37 m. Sampling was carried out between August and November 2009, December 2012, and September 2019 during the Seaflower Scientific Expedition. The algae collected were preserved in a 4% formalin/seawater solution. The identification was carried out using an optical microscope and specialized literature. All specimens were deposited in the herbarium JIW of the Biology Department of the Universidad Nacional de Colombia, Bogotá, Colombia. Key results: Eleven species of red macroalgae are newly reported for the Seaflower International Biosphere Reserve in the Caribbean Sea. Of these taxa, six have been previously reported for the Colombian Caribbean: Botryocladia spinulifera, Champia taironensis, Dasya caraibica, Pterocladiella bartlettii, Seirospora occidentalis, Spyridia aculeata subsp. complanata. The remaining five species are new records for the country: Botryocladia cf. bahamensis, Botryocladia cf. bermudana, Ceramium brevizonatum var. caraibicum Gloioderma iyoense and Wrightiella tumanowiczii. With these results the International Biosphere Reserve Seaflower hosts 153 species of Rhodophyta, belonging to 12 orders, 27 families and 73 genera. Conclusions: With the research carried out in the last 10 years, the number of registered taxa has increased from 202 to 325, which represents a 62% increase in the knowledge of macroalgae diversity and places the Archipelago in the second most diverse region in the Colombian Caribbean.

Resumen A la fecha, 18 especies del género de alga Lobophora (Dictyotales, Phaeophyceae) han sido registradas para el Gran Caribe. Sin embargo, solo 2 especies habían sido reportadas para la flora marina de Cuba, Lobophora variegata y Lobophora canariensis (como Aglaozonia canariensis). Para actualizar el conocimiento acerca del género Lobophora (Dictyotales, Phaeophyceae) en Cuba, se realizó un estudio morfológico exhaustivo recolectando macroalgas en la Reserva Ecológica Los Pretiles (Provincia Pinar del Río; mayo 2011), en el golfo de Guanahacabibes (Provincia Pinar del Río; junio 2014) y en la playa Calle 16 (Provincia La Habana; abril y mayo 2019). Las especies encontradas fueron: L. canariensis, L. declerckii, L. guadeloupensis, L. littlerorum y L. variegata. Las especies identificadas fueron depositadas en el Herbario del Acuario Nacional de Cuba (HANC). Aquí se presentan las descripciones morfológicas del material cubano. Adicionalmente, se muestra la distribución de estas especies en el Gran Caribe y se reporta por primera vez la especie L. guadeloupensis para las Grandes Antillas. Estos nuevos reportes incrementan la riqueza específica en Cuba y el rango de distribución de las especies de Lobophora en el Gran Caribe.

Abstract To date, 18 species of the algal genus Lobophora (Dictyotales, Phaeophyceae) have been reported for the Greater Caribbean Sea. Nevertheless, only 2 have been recorded for the marine flora of Cuba, Lobophora variegata and Lobophora canariensis (as Aglaozonia canariensis). To update the knowledge about this genus in Cuba, an exhaustive morphological study was performed using macroalgae collected from Western Cuba: Ecological Reserve Los Pretiles (Pinar del Río Province; May 2011), Gulf of Guanahacabibes (Pinar del Río Province; June 2014) and Calle 16 beach (La Habana Province; April and May 2019). The species found were: L. canariensis, L. declerckii, L. guadeloupensis, L. littlerorum and L. variegata. The identified species were deposited in the Cuban National Aquarium Herbarium (HANC). Morphological descriptions from Cuban material are here presented. In addition, the distribution of these species in the Greater Caribbean Sea is undertaken. We report for the first time L. guadeloupensis in the Greater Antilles. These new records increase the specific richness in Cuba and expand the distribution range of Lobophora species for the Greater Caribbean Sea.
