Journal of Fish Biology, Volume 107, Issue 5, Page 1669-1684, November 2025.Abstract The genus Farlowella has been historically challenging, in part due to the difficulty in defining diagnostic characters for defining and identifying the species. Farlowella colombiensis is one such example, whose diagnostic characters are based on caudal‐fin colour pattern, ventral pattern of body cover and anatomical details of the head, such

Biotropica, Volume 57, Issue 5, September 2025.Biogeographic knowledge of Amazonian amphibians is constrained by spatial and temporal coverage, leading to biases that affect the understanding of their diversity patterns. Using an extensive occurrence database, this study identified knowledge gaps and sampling biases linked to infrastructure and accessibility factors across the region.

Awareness of Grammatical Variability in Language Contact: The Case of Mano and Kpelle in Guinea
Journal of Sociolinguistics, Volume 29, Issue 4, Page 268-284, September 2025.ABSTRACT This paper contributes to research on the awareness of grammatical variability through a study of variation in reflexivity marking in Mano under the influence of Kpelle, both indigenous languages of Guinea. The speakers of these languages are found to be sensitive to contact‐induced grammatical variation in reflexivity, which manifests via ...
