Summary: We describe two new species of Draconura-clade semiaquatic anoles from Costa Rica, which are similar to Anolis aquaticus in appearance and ecology but differ in male dewlap coloration and scalation. These two new species, Anolis robinsoni sp. nov. and A. riparius sp. nov., can be distinguished mainly by their male dewlap color. Morphological traits and a phylogenetic analysis of mitochondrial DNA sequences confirm the distinctiveness of these three species. We also discuss the distribution and ecology of Anolis aquaticus and the new species.

Summary: The study aimed to analyze the impact of coronavirus awareness, psychological stress responses, and sociodemographic variables on mental health indicators in residents of Honduras, Chile, Costa Rica, Mexico, and Spain. The findings suggest that the COVID-19 pandemic has negative effects on the mental health of the general population, particularly in terms of anxiety, depression, and somatization. Specific populations, such as women and healthcare workers, are at higher risk of experiencing a decline in mental well-being.

Summary: This study provides evidence for the presence of non-biting midges of the subfamily Chironominae in the Mesozoic, based on descriptions of rare amber inclusions. A previously reported record from Late Cretaceous Taimyr amber has been revised and confirmed, with a new find in Burmese amber extending the temporal boundary of the subfamily. The discovery of two new genera in amber specimens sheds light on the phylogeny and diversification tempo of the Chironominae and Pseudochironomini in the past.

Summary: Stempellinella gilkai sp. nov., a non-biting midge of the subfamily Chironominae, tribe Tanytarsini, from the Eocene is described based on the adult male. This study provides a comparison of significant characters to delimit fossil Stempellinella and discusses key features of antenna and hypopygium. A comparative analysis of extinct and extant Stempellinella representatives led to an amendment of the current generic diagnosis, with notes on the genus' paleoecology and species richness during the Eocene.

Summary: This review presents the history of expeditions and studies on deep-sea echinoderms in Costa Rica, providing an updated list of species. It reveals that deep-sea echinoderms are highly diverse in both the Pacific Ocean and the Caribbean Sea, with Ophiuroidea being the most specious group. However, limited research has been done regarding the biology and ecology of these organisms, emphasizing the need for further studies to understand their ecological functions.

Summary: Prosthenorchis elegans is a parasite that infects non-human primates in the Americas, causing intestinal pathology that can be life-threatening. Squirrel monkeys in Costa Rica were found to be infected with P. elegans. Histopathological analysis showed a severe pyogranulomatous response characterized by the presence of macrophages, neutrophils, eosinophils, fibroblasts, and lymphocytes.

Summary: Studies have found that while there is a positive association between starchy vegetable consumption and MetS prevalence in Costa Rican adults, there is no significant trend after adjusting for confounders. Consuming total starchy vegetables and healthy starchy vegetables is significantly inversely associated with fasting blood glucose levels. Starchy vegetables may be part of a healthy dietary pattern in this population.

Summary: Tropical secondary forests play a crucial role in carbon sequestration and biodiversity conservation, but their recovery rates vary widely and are influenced by various environmental factors. Aboveground biomass recovers quickly in the early stages of succession, while tree species richness increases at a slower pace. Recovery rates differ significantly among forests.
