Evolutionary history of Middle American Rhamdia (Siluriformes: Heptapteridae) inferred from comparative mitogenomic data: Insights on historical biogeography and cave colonization in the group

Journal of Systematics and Evolution, Volume 63, Issue 6, Page 1501-1518, November 2025.
Investigating the systematics and biogeography of Neotropical catfishes of the genus Rhamdia refined phylogenetic hypotheses, including deep paraphyly of Rhamdia laticauda, supported northward dispersal catalyzed by emergence of the Panamanian Isthmus and imply that cave colonization is widespread, convergent, and recent, with established cave‐dwelling

Exploring the impact of chronic urticaria profile as a key predictor of alexithymia: A cross‐sectional study

Clinical and Translational Allergy, Volume 15, Issue 7, July 2025.
Abstract Introduction The relationship between chronic urticaria (CU) and alexithymia, a cognitive‐affective impairment characterized by difficulty in identifying and expressing emotions, is complex and underexplored. This study aimed to identify predictors of alexithymia in CU patients by focusing on the impact of coexisting mental illnesses and ...

Establishing an Ecuadorian Isoscape: The Importance of Baseline Strontium Data in a Volcanic Landscape Estableciendo un Iso‐Paisaje Ecuatoriano: La Importancia de los Datos de Referencia de Estroncio en un Paisaje Volcánico

American Journal of Biological Anthropology, Volume 187, Issue 2, June 2025.
ABSTRACT Objectives Strontium isotopes (87Sr/86Sr) have been used worldwide to track migrations and identify nonlocal individuals in the past. In South America, these studies often use comparative baseline maps, or isoscapes, established by samples from archaeological fauna and geologic formations. However, baseline research has focused on coastal Peru

Microplastic Occurrence in the Diet of Green Sea Turtles (Chelonia mydas) From the Coastal Region of São Paulo, Brazil

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 6, June 2025.
ABSTRACT Microplastics (MPs) represent the main vector of pollution in the marine environment. Originating from the slow degradation process of plastics into smaller particles, MPs vary in size between 1 and 5 mm. Their ability to adsorb and transport contaminants, disperse invasive organisms and be accidentally ingested by marine animals makes these ...

Gender dynamics and aspirational disparities in agriculture

Applied Economic Perspectives and Policy, Volume 47, Issue 1, Page 176-198, March 2025.
Abstract Despite increasing scholarly attention to individual aspirations, rural women's aspirations in agriculture remain largely unexplored. With women increasingly central to agricultural work, understanding their aspirations is crucial. Using farm surveys from Ecuador, Kenya, and Rwanda, we investigate the relationship between gender and aspiration

Fiddler Crabs (Crustacea: Decapoda: Ocypodidae) From Coastal Ecuador and the Galápagos Islands: Species Descriptions and DNA Barcodes

Ecology and Evolution, Volume 15, Issue 1, January 2025.
Twenty‐five taxa were collected during the surveys, while two more were noted from the literature and museum collections; five are new to Ecuador. DNA sequences for cytochrome c oxidase–subunit 1 were obtained for 27 operational taxonomic units with three morphologically indistinguishable cryptic or pseudo‐cryptic taxa were also revealed.
