Reef environments of murciélago islands and Santa Elena peninsula, Guanacaste conservation area, Costa Rican pacific
(2021)The ecology of the marine environments of the Murciélago Islands and the Santa Elena Peninsula have been studied little despite their high biodiversity. This area is influenced by a coastal upwelling. In 2014, 2016 and ... -
Percepción comunitaria sobre arrecifes coralinos en Golfo Dulce: bases para integración social en programas de restauración
(2023)Introduction: Addressing the accelerated coral reefs degradation requires integrated action at multiple social and ecological scales. At local level, active participation of the main users must be included. Objective: ... -
Status of coral reef communities on the caribbean coast of Costa Rica: Are we talking about corals or macroalgae
(2023)In the past decades, one of the most widely reported phenomena on Caribbean reefs is the general fall in coral cover and rise in macroalgae. Reefs with low coral cover and high macroalgal abundances are often presumed ... -
Applying the SES Framework to coral reef restoration projects on the Pacific coast of Costa Rica
(2023)Introduction: Global and local stressors have led to rapid declines in coral reef health. The high rates of coral degradation have motivated restoration initiatives worldwide. Evaluation of these initiatives has provided ... -
Southern hemisphere humpback whales (Megaptera novaeangliae) (Artiodactyla: balaenopteridae) singing activity at Caño Island Biological Reserve, Costa Rica before, during, and after COVID-19 lockdowns
(2023)Introduction: Boat traffic is recognized as a major contributor of underwater noise. Increasing presence of boats in coastal habitats is predicted to have important repercussions on the communication of marine mammals. In ... -
Black hole binaries with natal kicks
(2023)Las observaciones de más de 90 ondas gravitacionales observadas por la colaboración LIGO/VIRGO/KAGRA, han permitido obtener información sobre sistemas binarios compactos, como sus masas y espines. El parámetro de espín ... -
Nursery-reared coral outplanting success in an upwelling-influenced area in Costa Rica
(2023)Introduction: Environmental and intrinsic factors such as seawater temperature, salinity, nutrient concentration, upwelling, species, and life history can influence coral outplant survival and growth, and in consequence, ... -
Patterns of reef fish taxonomic and functional diversity in the Eastern Tropical Pacific
(2023)A core challenge in ecology is identifying the factors that determine species distribution and functional diversity of species assemblages. Reef fish are the most diverse group of vertebrates, form taxonomically rich and ... -
Echinoderm research perspectives: A Central American bibliometric review
(2021)Introduction: Central America, a narrow strip of land dividing the Atlantic and Pacific oceans, has a high diversity of marine and terrestrial species. Echinoderms are one of the most diverse marine groups with 420 reported ... -
Distribution and diversity of echinoderms (Asteroidea, Echinoidea, Holothuroidea) in the islands of the Gulf of Chiriqui, Panama
(2012-04)Los estudios de equinodermos en el Pacífico Panameño han sido enfocados principalmente en análisis moleculares y evolutivos, y los pocos trabajos ecológicos se han enfatizado en dos especies: Diadema mexicanum y Acanthaster ... -
Lissothuria caboblanquensis n. sp., a new species of sea cucumber (Holothuroidea: Dendrochirotida: Psolidae) from Costa Rica
(2014-05-23)A new species of sea cucumber of the genus Lissothuria Verrill, 1867 is described. Lissothuria caboblanquensis n. sp. was found in the Costa Rican Pacific, at 17 m depth. The presence of towers with spiny apex and the ... -
Bioerosion by the sea urchin Diadema mexicanum along Eastern Tropical Pacific coral reefs
(2016-07-07)Bioerosion is a natural process in coral reefs. It is fundamental to the health of these ecosystems. In the Eastern Tropical Pacific (ETP) coral reefs, the most important bioeroders are sponges, bivalves, sea urchins and ... -
Diversidad de los hábitats submareales de la Península de Santa Elena e Islas Murciélago, Pacífico Norte, Costa Rica
(2021-10-30)Introduction: Worldwide, coastal habitats are experiencing increasing pressure from pollution, coastal development, fisheries, and climate change. Identifying and recording coastal biodiversity is essential to assess ... -
Ascidian diversity of Costa Rica, including new records for the North Pacific
(2021-10-30)Introduction: The class Ascidiacea has about 3 000 species, which fulfill various roles in the ecosystem, for example, they filter high amounts of particles, and are shelter and food for other animals. Furthermore, the ... -
Succession of the sessile benthic community at a coral reef restoration site
(2023)Introduction: Ecosystem restoration facilitates ecological succession. When a coral reef experiences a disturbance, the community of sessile benthic organisms can follow a successional trajectory that favors the dominance ... -
Change in the composition of fauna associated with Pocillopora spp. (Scleractinia, Pocilloporidae) following transplantation
(2023-04-30)Introduction: Associated fauna comprises most of the diversity of a coral reef and performs ecological functions essential to the reef’s survival. Since Pocillopora corals harbor an important associated fauna, reef ... -
The origin and speciation of orchids
(2024)Orchids constitute one of the most spectacular radiations of flowering plants. However, their origin, spread across the globe, and hotspots of speciation remain uncertain due to the lack of an up-to-date phylogeographic ... -
The crown‑of‑thorns seastar species complex: knowledge on the biology and ecology of five corallivorous Acanthaster species
(2024-01)Coral-eating crown-of-thorns seastars (CoTS, Acanthaster spp.) are major contributors to the coral reef crises across the Indo-Pacific region. Until recently, CoTS throughout the Indo-Pacific were regarded to be a single ... -
