The marine fish genus Trachinotus (Carangidae: Trachinotinae) comprises species of considerable economic and ecological importance; however, a significant gap in genomic data has limited the understanding of its evolutionary history and systematics....

We used whole-genome sequencing to assemble the first complete mitogenome from a Mesentotoma Salmon, 1942 species. Mesentotoma was included in phylogenetic analyses along with 21 mitogenomes of other Entomobryinae. Maximum likelihood and Bayesian inf...

When analyzing the long-term viability of small, declining populations, it is essential to recognize that inbreeding and the erosion of genetic diversity are primarily driven by the effective population size, which is often a fraction of the total ce...

Fireworks are an important element of celebrations globally, and while there are multiple reports of their negative impact on both domestic and wild animals, there is limited data directly linking them to casualties. In this article, we present a cas...

The study of Palaearctic enchytraeid taxonomic richness revealed the limitations of applying morphological identification methods to certain species of the genus Cognettia. The use of molecular approaches enabled the identification of individuals bel...

Cyanobacteria of the genus Tychonema are common inhabitants of freshwater bodies in a temperate zones. In Lake Baikal, Tychonema sp. was first reported in 2014. It grows excessively on the bottom on almost all substrates types, forming epiphytic and...

“Placoderm” and sarcopterygian fishes dominated Devonian waters. Following the end-Devonian crisis, actinopterygians rapidly became major contributors to vertebrate diversity. This transition constitutes the first major diversification ev...

A fossil bird (MLP-PV 15-I-7-52) from Marambio (Seymour) Island, Antarctica, is described, representing the best-preserved skull reported for a Cretaceous neornithine and associated postcranial elements. Morphological analysis of the articular portio...

This study investigated the structure of the decapod crustacean community in first- and second-order coastal rivers of the Atlantic Forest in southern Bahia, focusing on taxonomic composition, abundance, richness, and distribution of species. The mai...

Successful escapes depend on many factors, including predator type and habitat characteristics. Examining escape usually entails directly pursuing an individual and then measuring flight initiation distance (FID), but the effect of prolonged pursuit...
