Estimating hatching success of egg clutches is essential for quantifying reproductive success in sea turtles. Thus, proper reporting is necessary to provide meaningful information for knowledge acquisition and management. ...
he recent widespread adoption of drones for studying marine animals provides
opportunities for deriving biological information from aerial imagery. The large
scale of imagery data acquired from drones is well suited for ...

Introduction: Costa Rica has been recognized worldwide for its high biodiversity and the conservation actions
it has implemented. One of the most iconic ecosystems are coral reefs, which have experienced strong anthropo-
genic ...
Understanding the threats to wildlife across space and time is essential for developing effective
conservation strategies. In Mesoamerica (i.e., the region that extends from Central Mexico to the
most southern point in ...

The barnacle Chelonibia testudinaria is arguably the most common and conspicuous epibiont on sea turtles. As evidence
suggests that C. testudinaria settles on turtles in coastal areas, this barnacle could serve as an ...

Global amphibian biodiversity has declined dramatically in the past 4 decades, and
many amphibian species have declined to near extinction as a result of emergence of the amphib-
ian chytrid fungus, Batrachochytrium ...
Biological and environmental conditions are drivers of fish habitat use, making it
essential to understand how fish move and use specific areas to inform effective fisheries manage-
ment and conservation. This study ...

Dissolved organic matter (DOM) contributes to the energy flow in tropical rivers that dominate the global budget
of riverine runoff to the ocean. Yet, the processes that control downstream DOM concentration and composition
in ...
Montalvo, Victor H.; Fuller, Todd K.; Sáenz-Bolaños, Carolina; Carrillo, Eduardo(Asociacion Mexicana de Mastozoologia, 2025-01-09)
Differential resource use of sympatric species that co-exist is poorly known. Considering sympatric procyonid species inhabiting the dry forest of northwest Costa Rica (Santa Rosa National Park) we hypothesized northern ...
Although diverse and abundant, the phylum Bryozoa has been the subject of few studies
in Costa Rica. Nearly 50 years have passed since Banta and Carson identified, described,
and published twenty-four bryozoan species, ...
Biologists have long been interested in the causes, costs, and benefits of group living. Within species, group sizes vary and affect the behavior of group members. Yet, few studies have investigated how behavioral ...
Fernández Ugalde, Roberto; Solórzano, Alejando(Revista Latinoamericana de Herpetología, 2025-04)
A novel case of predation of a juvenile Central American lyre snake Trimorphodon quadratus (Colubrida) by the Wandering spider Ancylometes bogotenensis (Ctenidae) in the Pacific northwestern region of Costa Rica is ...

Several specialised insects can manipulate normal plant development to induce a highly organised structure known as a gall, which represents one of the most complex interactions between insects and plants. Thus far, the ...
Lobo, Jorge A.; Cristóbal‐Pérez, Edson J.; Chavarría, María M.; Quesada, Mauricio(Wiley, 2025-03)
Analyses of the variation in the abortion rate and mass of seeds of tropical trees are scarce, despite their importance in modulat-
ing seed production, plant recruitment, and herbivore foraging patterns. We studied these ...
Porras-Brenes, Katherine; Ramírez-Mata, Nicole; Stynoski, Jennifer L.(Springer Science and Business Media LLC, 2024-04)
A key component of amphibian antipredator strategies is the chemical defenses that make them toxic and/or distasteful, like
the cardiotoxic bufadienolides synthesized by the true toads and stored in granular skin glands. ...
Stynoski, Jennifer L.; Porras-Brenes, Katherine(Springer Science and Business Media LLC, 2022-08)
The risk of predation and the costs and benefits of diverse anti-predator strategies can shift across the life stages of an
organism. Yet, empirical examples of ontogenetic switches in defense mechanisms are scarce. Anurans ...
López-Garro, Andrés; Zanella, Ilena(Revista de Biología Tropical, 2021-10)
Introduction: The bull shark, Carcharhinus leucas, is particularly vulnerable to anthropogenic actions because of its permanence in coastal ecosystems; populations depletion is registered in different places around the ...
