Introduction The distal interphalangeal joint (DIPJ) plays a crucial role in the function of the hoof and digit. Dislocations and subluxations in this region are rare and primarily of traumatic origin. Case Report This case report aims to describe two unusual cases of open DIPJ dislocation, including clinical presentation, diagnostic workup, treatment, and long-term follow-up. Both animals presented with open traumatic distal...

The early ontogeny of endemic freshwater fishes provides essential baseline biological information for conservation and management, particularly in species with restricted distributions and high vulnerability to habitat degradation, environmental change and population decline. This study presents the first detailed description of embryonic and larval development of Tlaloc hildebrandi , an endangered (EN) killifish endemic to C...

Life-history theory predicts trade-offs between offspring number and offspring size as a central mechanism shaping reproductive strategies in animals. Variation in egg size, fecundity, and parental care influences early survival and evolutionary diversification. Yet how closely related species integrate reproductive behavior and parental care with offspring size and fecundity remains poorly understood. We compared two closely...

Effective conservation and enforcement strategies for marine turtles depend on understanding population structure, connectivity, and the geographic origins of turtles impacted by threats such as bycatch, overexploitation, and illegal trade. However, mitochondrial DNA (mtDNA) data remain fragmented across studies, with inconsistent sequence lengths, haplotype nomenclature, and metadata standards limiting their application in co...

Summary Despite the ongoing intensive efforts on disentangling the diversity of the genus Carex (Cyperaceae) in South America, there is much still to be accomplished. In this note we studied collections from some of the main South American and North American herbaria, new field collections, and observations from the citizen platform iNaturalist, to report chorological, nomenclatural, and taxonomic notes for 16 South American C...

Aim Carex section Echinochlaenae has a disjunct distribution across the Southern Hemisphere. It displays a clear center of diversity in New Zealand coupled with extreme morphological and ecological diversification, suggesting a potential evolutionary radiation. We aimed to reconstruct the biogeographic history of the group and evaluate bioclimatic niche evolution during colonization and diversification events. Location Souther...

Human‐induced high densities of large wild herbivores may pose a threat to natural ecosystems, modifying biodiversity and ecosystem functioning. Although the negative impacts on individual taxa and processes are well documented, a comprehensive understanding of how ecosystem integrity responds to high herbivore densities remains limited. This study addresses this gap through an extensive herbivore‐density manipulation experime...
