Biodiversity conservation is a complex and transdisciplinary problem that requires engagement and cooperation among scientific, societal, economic, and political institutions. However, historical approaches have often failed to bring together and address the needs of all relevant stakeholders in decision‐making processes. The Tropical Andes, a biodiversity hotspot where conservation efforts often conflict with socioeconomic issues and policies that prioritize economic development, provides an ideal model to develop and implement more effective approaches. In this study, we present a co‐design approach that mainstreams and improves the flow of biodiversity information in the Tropical Andes, while creating tailored outputs that meet the needs of economic and societal stakeholders. We employed a consultative process that brought together biodiversity information users and producers at the local, national, and regional levels through a combination of surveys and workshops. This approach identified priority needs and limitations of the flow of biodiversity information in the region, which led to the co‐design of user‐relevant biodiversity indicators. By leveraging the existing capacities of biodiversity information users and producers, we were able to co‐design multiple biodiversity indicators and prioritize two for full implementation ensuring that the data was findable, accessible, interoperable, and reusable based on the FAIR principles. This approach helped address limitations that were identified in the stakeholder engagement process, including gaps in data availability and the need for more accessible biodiversity information. Additionally, capacity‐building workshops were incorporated for all producers of biodiversity information involved, which aimed to not only improve the current flow of biodiversity information in the region but also facilitate its future sustainability. Our approach can serve as a valuable blueprint for mainstreaming biodiversity information and making it more inclusive in the future, especially considering the diverse worldviews, values, and knowledge systems between science, policy, and practice.

La conservación de la biodiversidad es un problema complejo y transdisciplinario que requiere el compromiso y la cooperación entre instituciones científicas, sociales, económicas y políticas. Sin embargo, los enfoques tradicionales/convencionales  a menudo no logran  reunir y abordar las necesidades de todos los actores relevantes en los procesos de toma de decisiones. Los Andes tropicales, un área clave  de biodiversidad donde los esfuerzos de conservación a menudo entran en conflicto con cuestiones socioeconómicas y políticas que priorizan el desarrollo económico, proporcionan un modelo ideal para desarrollar e implementar enfoques más efectivos. En este estudio, presentamos un enfoque co-diseño que integra y mejora el flujo de información sobre biodiversidad en los Andes tropicales, creando resultados personalizados que satisfacen las necesidades, tanto económicas como sociales, de las partes interesadas. Empleamos un proceso de consulta que reunió a usuarios y productores de información sobre biodiversidad a nivel local, nacional y regional, a través de encuestas y talleres. Este enfoque ha permitido identificar necesidades prioritarias y limitaciones del flujo de información sobre biodiversidad en la región; lo cual llevó al codiseño de indicadores de biodiversidad relevantes para los usuarios. Aprovechando las capacidades existentes de los usuarios y productores de información sobre biodiversidad, pudimos co-diseñar múltiples indicadores de biodiversidad y priorizar dos de estos para su implementación completa, asegurando que los datos sean localizables, accesibles, interoperables y reutilizables, según los principios FAIR. Este enfoque ayudó a abordar las limitaciones que se identificaron en el proceso de participación de las partes interesadas; incluidas las brechas en la disponibilidad de datos y la necesidad de información sobre biodiversidad más accesible. Además, se incorporaron talleres de desarrollo de capacidades para todos los productores de información sobre biodiversidad involucrados, los cuales apuntaron no sólo a mejorar el flujo actual de información sobre biodiversidad en la región, sino también facilitar su sostenibilidad futura. Nuestro enfoque puede servir como un modelo valioso para incorporar la información sobre biodiversidad y hacerla más inclusiva en el futuro; especialmente si consideramos las diversas perspectivas globales, valores y sistemas de conocimiento implicados en las interacciones entre  la ciencia, la política y su aplicación práctica.

A conservação da biodiversidade é um problema complexo e transdisciplinar que requer compromisso e cooperação entre instituições científicas, sociais, económicas e políticas. No entanto, as abordagens tradicionais/convencionais muitas vezes não conseguem reunir e responder às necessidades de todos os intervenientes relevantes nos processos de tomada de decisão. Os Andes tropicais, uma área chave para a biodiversidade onde os esforços de conservação entram frequentemente em conflito com questões socioeconómicas e políticas que dão prioridade ao desenvolvimento económico, fornecem um modelo ideal para desenvolver e implementar abordagens mais eficazes. Neste estudo, apresentamos uma abordagem de co-design que integra e melhora o fluxo de informações sobre biodiversidade nos Andes tropicais, criando resultados personalizados que atendem às necessidades, tanto econômicas quanto sociais, das partes interessadas. Empregamos um processo de consulta que reuniu usuários e produtores de informações sobre biodiversidade nos níveis local, nacional e regional, por meio de pesquisas e workshops. Esta abordagem permitiu identificar necessidades prioritárias e limitações do fluxo de informação sobre a biodiversidade na região; o que levou à concepção conjunta de indicadores de biodiversidade relevantes para os utilizadores. Aproveitando as capacidades existentes dos utilizadores e produtores de informação sobre biodiversidade, fomos capazes de conceber em conjunto vários indicadores de biodiversidade e priorizar dois deles para implementação total, garantindo que os dados sejam localizáveis, acessíveis, interoperáveis ​​e reutilizáveis, de acordo com os princípios FAIR. Esta abordagem ajudou a resolver as limitações identificadas no processo de envolvimento das partes interessadas; incluindo lacunas na disponibilidade de dados e a necessidade de informações mais acessíveis sobre biodiversidade. Além disso, foram incorporados workshops de capacitação para todos os produtores de informação sobre biodiversidade envolvidos, que visaram não só melhorar o fluxo actual de informação sobre biodiversidade na região, mas também facilitar a sua sustentabilidade futura. A nossa abordagem pode servir como um modelo valioso para incorporar informações sobre biodiversidade e torná-las mais inclusivas no futuro; especialmente se considerarmos as diversas perspectivas globais, valores e sistemas de conhecimento envolvidos nas interações entre ciência, política e sua aplicação prática.

SIGNIFICANCE: Load shedding has become the norm in South Africa. These rolling blackouts currently range from Stage 1 to Stage 6. Households are disempowered for 2-4 hours and for an average of 1.5-9 hours per day. In financially unequal South Africa, heavy users can afford battery backup solutions to keep the lights on. However, installing these at scale, without solar generation, eventually neuters the utility's ability to stabilise the grid and avert a blackout with shedding. Here we assess and quantify the impact of these interventions using an electricity data set of 12 000 households.

Resumen Introducción: Las especies de Mesochorus se encuentran en todo el mundo y los miembros de este género son principalmente hiperparasitoides de las familias Ichneumonoidea y Tachinidae. Objetivos: Describir las especies de Mesochorus costarricenses obtenidas de orugas y en menor medida por trampas Malaise. Métodos: Las especies se diagnosticaron mediante el uso de código de barra molecular por COI del ADNmt, inspección morfológica y datos del huésped. Se proporciona un conjunto de imágenes y datos de los huéspedes (planta, oruga y parasitoide primario) para cada especie. Resultados: Se encontró un total de 158 nuevas especies de Mesochorus. Sharkey es la autoridad taxonómica para todas las especies. Conclusiones: Se demuestra una aplicación práctica del código de barras de ADN que se puede aplicar a grandes cantidades de especies de insectos neotropicales no descritas para grupos hiperdiversos.

Abstract Introduction: Species of Mesochorus are found worldwide and members of this genus are primarily hyperparasitoids of Ichneumonoidea and Tachinidae. Objectives: To describe species of Costa Rican Mesochorus reared from caterpillars and to a lesser extent Malaise-trapped. Methods: The species are diagnosed by COI mtDNA barcodes, morphological inspection, and host data. A suite of images and host data (plant, caterpillar, and primary parasitoid) are provided for each species. Results: A total of 158 new species of Mesochorus. Sharkey is the taxonomic authority for all. Conclusions: This demonstrates a practical application of DNA barcoding that can be applied to the masses of undescribed neotropical insect species in hyperdiverse groups.

SIGNIFICANCE: The current initiative to export African cheetahs to India has a limited scientific basis, placing the Asian subspecies and the translocated animals at risk. There is no evidence that this will benefit African cheetah conservation. We call for a globally coordinated approach to cheetah conservation, based on sound science

SIGNIFICANCE: Mentorship has always been a key component of postgraduate student education, and it is becoming increasingly important in the academic environment. Strong mentorship is widely recognised as a key aspect of professional development and career success. Our view is that mentorship is a lifelong process extending beyond just teaching, and encompasses a wide range of aspects of the relationship between someone who is more experienced and someone who is less experienced people. We see this as a two-way process, where both mentee and mentor benefit. It is ideally a personal relationship in which mentors are well respected in their fields, earning the respect of their mentees, who benefit from the ideas, insights and skills of their mentors. We argue that the lives and careers of both students and academics would benefit from universities establishing formal, non-bureaucratic structures to promote positive mentorship.

RESUMO Objetivo. Descrever o desenvolvimento de materiais educativos para pais e outros cuidadores de crianças com câncer por meio de uma abordagem sensível à cultura para reduzir as barreiras de aceitação dos cuidados paliativos (CP). Métodos. A Organização Pan-Americana da Saúde (OPAS), o St. Jude Children's Research Hospital e parceiros da América Latina e do Caribe colaboraram em um projeto de três fases, que iniciou com uma pesquisa de avaliação das necessidades dos cuidadores de crianças com câncer no Peru. Com base nos achados dessa pesquisa, uma equipe interdisciplinar de especialistas em CP pediátricos desenvolveu um conteúdo educacional que foi concebido e validado por um comitê internacional de especialistas em CP e comunicação. Resultados. A colaboração resultou no desenvolvimento de uma série de oito módulos que apresenta os principais conceitos dos CP pediátricos aos cuidadores, incluindo controle da dor, qualidade de vida e cuidados de final de vida. A série foi concebida para reduzir o estigma dos cuidadores em relação aos CP por meio de educação sensível à cultura, abordando os baixos níveis de letramento em saúde entre os cuidadores da América Latina e do Caribe. Nos 15 meses desde seu lançamento, os módulos foram distribuídos em toda a América Latina, tendo sido baixados 2 825 vezes. Conclusões. Os materiais educativos e a orientação prévia sobre CP foram considerados uma prioridade para os pais e outros cuidadores de crianças com câncer em toda a América Latina. Os materiais desenvolvidos por meio desse projeto foram amplamente utilizados e estão disponíveis no site da OPAS e no recurso on-line Together by St. Jude™.

ABSTRACT Objective. To describe the development of educational materials for parents and other caregivers of children with cancer, which utilized a culturally sensitive approach to reduce acceptance barriers to palliative care (PC). Methods. The Pan American Health Organization (PAHO), St. Jude Children’s Research Hospital, and partners in Latin America and the Caribbean collaborated in a three-phase project, beginning with a needs assessment survey of caregivers of children with cancer in Peru. Based on this finding, an interdisciplinary team of pediatric PC experts developed educational content that was designed and validated by an international committee of PC and communication experts. Results. The collaboration resulted in the development of an eight-module series that introduces caregivers to key concepts of pediatric PC, including management of pain, quality of life, and end of life care. The series was designed to reduce caregiver stigma associated with PC through culturally sensitive education that addresses the low levels of health literacy among caregivers in Latin America and the Caribbean. In the 15 months since the launch, these modules have been distributed throughout Latin America and were downloaded 2 825 times. Conclusions. Educational materials and anticipatory guidance of PC were considered to be a priority for parents and other caregivers of children with cancer throughout Latin America. The materials developed through this project have been widely utilized and are available through the PAHO website and the Together by St. Jude™ online resource.

RESUMO A Iniciativa Global para o Câncer Infantil tem como objetivo aumentar a taxa de cura de crianças com câncer no mundo todo, melhorando o acesso a cuidados e a qualidade da assistência médica. A Organização Pan-Americana da Saúde (OPAS), o St. Jude Children's Research Hospital (St. Jude) e colaboradores uniram esforços para melhorar o desfecho de crianças com câncer na América Latina e no Caribe (ALC) no âmbito do marco CureAll. Neste artigo, descrevemos o processo de desenvolvimento de recursos regionais com o objetivo de acelerar a implementação da Iniciativa na ALC. Em março de 2021, a OPAS formou grupos de trabalho regionais para desenvolver projetos centrais alinhados com os pilares e facilitadores do CureAll. A partir das reuniões de diálogo regionais, foram criados sete grupos de trabalho: detecção precoce, enfermagem, atenção psicossocial, nutrição, cuidados de suporte, abandono do tratamento e cuidados paliativos. A OPAS organizou reuniões virtuais regulares sob a orientação e o apoio dos programas regionais e transversais do St. Jude e de mentores internacionais. Entre abril e dezembro de 2021, 202 especialistas multidisciplinares participaram de 43 reuniões virtuais para promover o diálogo entre as partes interessadas a fim de melhorar os desfechos do câncer infantil. Foram produzidos 14 materiais técnicos: quatro panoramas regionais, quatro documentos técnicos, dois cursos virtuais, um conjunto de perfis epidemiológicos nacionais, uma série de conteúdo educacional para pais e cuidadores e duas campanhas de comunicação. O diálogo e o compromisso contínuos da OPAS, do St. Jude, dos comitês de trabalho da ALC e dos colaboradores internacionais são bases essenciais para acelerar com sucesso a implementação da Iniciativa Global para o Câncer Infantil. Isso é possível por meio do desenvolvimento de materiais de relevância regional e mundial. São necessárias mais pesquisas e avaliações para determinar o impacto dessas estratégias e recursos nos resultados do câncer infantil na ALC e em outras regiões.

RESUMEN La Iniciativa Mundial contra el Cáncer Infantil tiene como objetivo aumentar a nivel mundial la tasa de curación del cáncer infantil mediante la mejora del acceso a la atención de salud y de su calidad. La Organización Panamericana de la Salud (OPS), el St. Jude Children’s Research Hospital y los colaboradores han aunado esfuerzos para mejorar los resultados en la población infantil con cáncer en América Latina y el Caribe valiéndose del marco CureAll. En este artículo describimos el proceso de elaboración de recursos regionales destinados a acelerar la aplicación de la Iniciativa Mundial en América Latina y el Caribe. En marzo del 2021, la OPS formó grupos de trabajo regionales para elaborar proyectos básicos que estuvieran en consonancia con los pilares y los elementos facilitadores del CureAll. De los diálogos regionales surgieron siete grupos de trabajo: detección temprana, enfermería, aspectos psicosociales, nutrición, tratamientos de apoyo, abandono del tratamiento y cuidados paliativos. La OPS organizó con regularidad reuniones virtuales en las que se contó con la tutoría y el apoyo de programas regionales o transversales del St. Jude Children’s Research Hospital y de mentores internacionales. Entre abril y diciembre del 2021 hubo 43 reuniones virtuales a las que asistieron 202 expertos multidisciplinarios, con el objetivo de promover el diálogo entre las partes interesadas para mejorar los resultados en materia de cáncer infantil. Se elaboraron catorce productos técnicos: cuatro panoramas regionales, cuatro documentos técnicos, dos cursos virtuales, un conjunto de perfiles epidemiológicos de países, una serie con contenidos educativos para padres y cuidadores y dos campañas de comunicación. El diálogo y el compromiso constantes de la OPS, el St. Jude Children’s Research Hospital, los comités de trabajo de América Latina y el Caribe y los colaboradores internacionales son las bases fundamentales para conseguir que se acelere la aplicación de la Iniciativa Mundial. Esto se puede lograr mediante la elaboración de materiales que resulten pertinentes a nivel regional y mundial. Son necesarias más investigaciones y evaluaciones para determinar el impacto que tienen estas estrategias y recursos en los resultados que se obtienen en el cáncer infantil en América Latina y el Caribe y en otras subregiones.

ABSTRACT The Global Initiative for Childhood Cancer (GICC) aims to increase the cure rate for children with cancer globally by improving healthcare access and quality. The Pan American Health Organization (PAHO), St. Jude Children’s Research Hospital (St. Jude), and collaborators have joined efforts to improve outcomes of children with cancer in Latin America and the Caribbean (LAC) using the CureAll framework. In this article, we describe the process of developing regional resources aimed at accelerating the GICC implementation in LAC. In March 2021, PAHO formed regional working groups to develop core projects aligned with CureAll pillars and enablers. Seven working groups emerged from regional dialogues: early detection, nursing, psychosocial, nutrition, supportive care, treatment abandonment, and palliative care. PAHO arranged regular online meetings under the mentorship and support of St. Jude regional/transversal programs and international mentors. Between April and December 2021, 202 multidisciplinary experts attended 43 online meetings to promote the dialogue between stakeholders to improve childhood cancer outcomes. Fourteen technical outputs were produced: four regional snapshots, four technical documents, two virtual courses, one set of epidemiological country profiles, one educational content series for parents/caregivers, and two communication campaigns. The ongoing dialogue and commitment of PAHO, St. Jude, LAC working committees, and international collaborators are essential foundations to successfully accelerate GICC implementation. This is achievable through the development of materials of regional and global relevance. Further research and evaluation are needed to determine the impact of these strategies and resources on childhood cancer outcomes in LAC and other regions.

BACKGROUND: Sorocephalus imbricatus (Thunb.) R.Br. is a range-restricted species endemic to the Cape Floristic Region (CFR), South Africa. It is currently classified as Critically Endangered in accordance with the IUCN criteria. Like many other species endemic to the CFR, S. imbricatus is subjected to several major threats including habitat loss, habitat degradation and the impacts of invasive alien species. Sorocephalus imbricatus was recently identified as a species requiring improved representation in ex-situ collections. During field work undertaken to collect germplasm for this purpose, a concerning number of dead and dying plants were observed. OBJECTIVES: To determine the cause of rapid death of individuals in a remnant subpopulation of S. imbricatus. METHOD: A field visit to a subpopulation of the only extant population, Elands-kloof, was conducted to examine the symptoms associated with S. imbricatus mortality, and to collect samples for isolation and identification of putative pathogens. RESULTS: Dead and dying plants showed clear symptoms of root and collar rot, with Phytophthora cinnamomi Rands recovered from all samples. The collections highlighted the severe impact of P. cinnamomi on S. imbricatus, with the size of the subpopulation being reduced from 62 to 37 individuals (a 40% reduction) between October 2021 and May 2022. CONCLUSION: This study describes, for the first time, rapid mortality of the Critically Endangered Proteaceae species, S. imbricatus, likely caused by the invasive pathogen P. cinnamomi. This concerning discovery highlights the urgent need for greater recognition of the threat P. cinnamomi poses not only to S. imbricatus, but to the broader floristic diversity of the CFR. Importantly, it illustrates a need for a substantial body of work to be undertaken to address a significant lack of knowledge regarding the relative threat that P. cinnamomi poses to species of the CFR.

BACKGROUND: Much of the Grassland Biome in South Africa is prone to shrub encroachment, leading to loss of ecosystem services, habitat heterogeneity and species diversity. Burrowing mammals are an important component of grasslands as these animals create microhabitats for other taxa, including smaller mammal species, birds, reptiles and invertebrates. However, our understanding of how shrub encroachment affects burrowing mammals is poor OBJECTIVES: Here we assessed the relationship between burrow abundance and bankrupt bush, Seriphium plumosum, encroachment as well as burrowing mammal diversity in bankrupt bush encroached and non-encroached grasslands METHOD: Shrub density, medium and large mammal burrow abundance and density were measured in 24 encroached and 24 non-encroached areas randomly selected in the Telperion Nature Reserve, Mpumalanga, South Africa. In addition, burrowing mammal diversity was assessed using camera traps in a subset of six encroached and six non-encroached areas RESULTS: Our results show that the abundance and density of medium and large burrows were significantly lower in encroached areas than in non-encroached areas (p = 0.011 and p < 0.001, respectively). The relationship between burrow abundance and bankrupt bush encroachment was negative (rho = -0.456, p = 0.001). However, burrowing mammal diversity had no significant difference between encroached and non-encroached areas CONCLUSION: Our data, therefore, suggest that with increasing bankrupt bush encroachment and a decreased abundance in burrowing mammal ecosystem services, a negative effect will occur on burrowing mammal communities, leading to the reduction in species-specific habitat heterogeneity and possibly animal biodiversity

The biodiversity of plant resources is a renewable source that can use as a sustainable component in various applications. The use of vegetable waste as a filler element in polymeric composites is part of the solid waste management policy and the sustainable development of agribusiness. In this work, the natural rubber composites were prepared with acai seed in proportions of 0, 10, 20, 30, 40, and 50 phr (per hundred rubber). The composites were homogenized in an open cylinder mixer and characterized by rheometric, morphological, mechanical, and thermal tests. The addition of the organic fillers significantly reduced the vulcanization process time. Thermogravimetric analysis and infrared spectroscopy showed that the composites were thermally stable and showed no structure changes after the vulcanization process, respectively. The Lorenz-Parks method's evaluation of matrix/filler interactions showed a strong interaction between NR/Acai. The new biocomposite can replace non-ecological composites economically and sustainably.

Objective: To improve the ability of psychiatry researchers to build, deploy, maintain, reproduce, and share their own psychophysiological tasks. Psychophysiological tasks are a useful tool for studying human behavior driven by mental processes such as cognitive control, reward evaluation, and learning. Neural mechanisms during behavioral tasks are often studied via simultaneous electrophysiological recordings. Popular online platforms such as Amazon Mechanical Turk (MTurk) and Prolific enable deployment of tasks to numerous participants simultaneously. However, there is currently no task-creation framework available for flexibly deploying tasks both online and during simultaneous electrophysiology. Methods: We developed a task creation template, termed Honeycomb, that standardizes best practices for building jsPsych-based tasks. Honeycomb offers continuous deployment configurations for seamless transition between use in research settings and at home. Further, we have curated a public library, termed BeeHive, of ready-to-use tasks. Results: We demonstrate the benefits of using Honeycomb tasks with a participant in an ongoing study of deep brain stimulation for obsessive compulsive disorder, who completed repeated tasks both in the clinic and at home. Conclusion: Honeycomb enables researchers to deploy tasks online, in clinic, and at home in more ecologically valid environments and during concurrent electrophysiology.

Abstract For 175 years, an unremarkable bass, the Grape-eye Seabass (Hemilutjanus macrophthalmos), has been known from coastal waters in the Eastern Pacific. To date, its phylogenetic placement and classification have been ignored. A preliminary osteological examination of Hemilutjanus hinted that it may have affinities with the Acropomatiformes. To test this hypothesis, we conducted a phylogenetic analysis using UCE and Sanger sequence data to study the placement of Hemilutjanus and the limits and relationships of the Acropomatiformes. We show that Hemilutjanus is a malakichthyid, and our results corroborate earlier studies that have resolved a polyphyletic Polyprionidae; accordingly, we describe Stereolepididae, new family, for Stereolepis. With these revisions, the Acropomatiformes is now composed of the: Acropomatidae; Banjosidae; Bathyclupeidae; Champsodontidae; Creediidae; Dinolestidae; Epigonidae; Glaucosomatidae; Hemerocoetidae; Howellidae; Lateolabracidae; Malakichthyidae; Ostracoberycidae; Pempheridae; Pentacerotidae; Polyprionidae; Scombropidae; Stereolepididae, new family; Symphysanodontidae; Synagropidae; and Schuettea. Finally, using our new hypothesis, we demonstrate that acropomatiforms repeatedly evolved bioluminescence and transitioned between shallow waters and the deep sea.

Resumen Durante más de 175 años el Serranido ojo de uva (Hemilutjanus macrophthalmos), un pez parecido a la lubina común, se conoce de las zonas costeras del Pacífico Oriental. Al día de hoy la posición filogenética de esta especie se desconoce. Un estudio preliminar de Hemilutjanus basado en caracteres osteológicos sugirió que esta especie puede tener afinidades con el orden Acropomatiformes. Para investigar la posición filogenética de Hemilutjanus y los límites y relaciones dentro del orden Acropomatiformes realizamos análisis filogenéticos utilizando datos de secuencias Sanger y de UCEs. Demostramos que Hemilutjanus es un malakichthyid y nuestros resultados recobran Polyprionidae como una familia polifilética corroboran así estudios anteriores. En consecuencia, diagnosticamos y describimos una nueva familia de peces, Stereolepididae, que incluye ambas especies del genero Stereolepis. Con esta revisión, ahora el orden Acropomatiformes se compone de las familias: Acropomatidae; Banjosidae; Bathyclupeidae; Champsodontidae; Creediidae; Dinolestidae; Epigonidae; Glaucosomatidae; Hemerocoetidae; Howellidae; Lateolabracidae; Malakichthyidae; Ostracoberycidae; Pempheridae; Pentacerotidae; Polyprionidae; Scombropidae; Stereolepididae, nueva familia; Symphysanodontidae; Synagropidae; y Schuettea. Finalmente, utilizando nuestra hipótesis filogenética, demostramos que bioluminiscencia ha evolucionado varias veces dentro de los miembros de Acropomatiformes y tambien demostramos múltiples transiciones entre aguas someras y zonas profundas del océano dentro de este grupo.

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.
