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 ... -
Predators of the sea urchin Diadema mexicanum (Diadematoida: Diadematidae) at the Eastern Tropical Pacific coral reefs
(2024)Introduction: The coral reefs of Isla del Coco National Park are some of the most pristine ecosystems on Earth. The sea urchin Diadema mexicanum (Diadematoida: Diadematidae) is a common inhabitant with a pivotal role in ... -
A posteriori error analysis of a semi-augmented finite element method for double-diffusive natural convection in porous media
(2024)This paper presents our contribution to the a posteriori error analysis in 2D and 3D of a semi-augmented mixed-primal finite element method previously developed by us to numerically solve double-diffusive natural convection ... -
Variation of the diet of the sea urchin (Diadema mexicanum (Diadematoida: Diadematidae)) according to its size in the Eastern Tropical Pacific
(2024-03)Introduction: The sea urchin Diadema mexicanum, due to its bioerosion activity, is considered of ecological importance. This phenomenon could negatively or positively affect coral reef ecosystems. The bioerosion process varies ... -
Central America urgently needs to reduce the growing adaptation gap to climate change
(2023-11-24)Central America is highly impacted by current extreme events associated with climate variability and the adverse effects of climate change, showing high vulnerability compounded by its historical context and socioeconomic ... -
Climate variability of precipitation in Ceará Region, Northeast of Brazil
(2023-11-20)The state of Ceará is a semi-arid region located in the Northeast region of Brazil, characterized by an irregular rainy season, great climate variability mainly driven by the El Niño–Southern Oscillation (ENSO), Sea Surface ... -
Characterization of principal bundles: the noncommutative algebraic case
(2024)We review Hopf–Galois extensions, in particular faithfully flat ones, accepted to be the noncommutative algebraic dual of a principal bundle. We also make a short digression into how quantum groups relate to Hopf—Galois ... -
