. Lontra longicaudis Olfers, 1818 is a semi-aquatic carnivore widely distributed in the Neotropical region. Understanding their diet contributes to an indirect understanding of their ecology and the composition of the local fauna. To this end, we analyzed 109 fecal samples and identified 238 morphological structures; these samples were collected between May 2006 and September 2007 from the Santa Lúcia Biological Station (SLBS) in southeastern Brazil. The area is intersected by the Timbuí River, which arrives at the site after crossing the urban perimeter of the city of Santa Teresa in the state of Espírito Santo. We found a predominance of fish in the otters’ diets (82%), mainly cichlids (50%), which are fish with sedentary habits and low mobility levels. The crustacean Trichodactylus fluviatilis Latreille, 1828 was the third most consumed taxon; this occurred mainly during the rainy season, corresponding to the crustacean’s reproductive period, when it is more vulnerable to predation. Otters exhibited a seasonal variation in their prey selectivity. Furthermore, they displayed opportunistic foraging behavior, as the most preyed fish were those with both low mobility and a high frequency in the environment, followed by fish with high mobility and high frequency, and then those with low mobility and low frequency. We concluded that the feeding habits of the otters in the SLBS are in line with the optimal foraging theory since prey selection was optimized through the balance between net energy gained and the energy costs of foraging.

. Artibeus amplus Handley, 1987 is a little-known bat species endemic to northern South America. There are confirmed records of the species for Colombia, Venezuela, Guyana, and Suriname. In this study, we report the occurrence of A. amplus in Brazil based on the collection of two specimens captured in the munic-ipalities of Cantá and Caracaraí in the state of Roraima. We also found a museum specimen from the state of Amazonas. The specimens were identified based on morphology and mitochondrial Cytochrome b gene analysis. After this contribution, the number of bat species in Brazil is 182. Surveys in other areas in the north of the country, such as the state of Pará, in addition to a comprehensive review of museum specimens, is needed to investigate the distribution of the species in areas where it has not been found yet.

. Migratory fishes have high ecological, social, and commercial value, and are strongly affected by river regulation. This study aimed to understand how migratory fishes use the longitudinal gradient, in an upstream to downstream direction of two free-flowing rivers and two reservoirs in a cascade within the Upper Grande River Basin, Brazil. The numeric abundance, biomass, richness, presence of fingerlings and juveniles, and the macroscopic gonadal maturation stage of migratory fishes were ascertained and evaluated bimonthly for two years. Recruitment in migratory fishes seems to rely completely on the free-flowing rivers upstream and their floodplains. Transition areas do not seem to have a significant role in recruitment. Therefore, we highlight the importance of maintaining the free flow of rivers and the integrity of their floodplains.

. In 2022, Salvador and co-authors published an up-to-date list of gastropod species recorded from Brazilian caves. That list included 18 species (15 land and three freshwater species) that were considered by the authors to be restricted to caves (troglobitic). In this contribution we argue that only six of the species listed by them as truly troglobites can be classified in that category. We disagree with some characteristics listed by Salvador and co-authors to diagnose the species they classify as cave-restricted and argue that those species do not have truly troglomorphic traits (characteristic of subterranean habitats). Since the Brazilian legislation considers the degree of association with caves as a decisive attribute to preserve them, it is important to clarify the characteristics are sufficient and necessary for a species to be classified as cave-dependent.

. We describe a gland in the arthrodial membrane of the coxa-trochanter articulation in the fourth pair of legs in the Neotropical harvester Mischonyx squalidus Bertkau, 1880. Externally the glandular area has a rough appearance with pores on its surface, with folds of the arthrodial membrane. Internally, its secretory cells have spherical secretory vesicles, smooth endoplasmic reticulum, mitochondria and ducts that exit from the cells and cross the arthrodial membrane. Histochemical tests indicate the presence of proteins and neutral glycoproteins. The function of the gland might be to produce lubricating products that allow better movement of the coxa-trochanter region.

. Eptesicus Rafinesque, 1820 is widely distributed in the Old and New World (26 species), and Histio-tus Gervais, 1856 is a South American endemic (11 species). Molecular phylogenies have recovered Eptesicus (sensu lato) as polyphyletic, with New World Eptesicus and the sister genus Histiotus in a paraphyletic American clade sister to Old World Eptesicus . Based on these phylogenetic reconstructions, authors have treated Histiotus as either a subgenus of Eptesicus or restricted Eptesicus to the New World species, treating Histiotus as a full genus, and using the name Cnephaeus Kaup, 1829 at the generic rank to comprise Old World Eptesicus . Based on recently published molecular studies, and on novel qualitative and quantitative morphological comparisons of representatives of Histiotus and New and Old World Eptesicus , we provide evidence for restricting the name Eptesicus to the species E. fuscus (Palisot de Beauvois, 1796) and E. guadeloupensis Genoways & Baker, 1975, allocating the remaining New World species under a new genus, keeping Histiotus as a full genus, and raising Cnephaeus to generic rank to comprise all Old World taxa currently under Eptesicus . This arrangement resolves the paraphyly of New World Eptesicus , and promotes taxonomic stability for Histiotus , which is a well-established genus of easily recognizable Neotropical bats and treated separate from Eptesicus by most authorities.

. This study aimed to estimate the parameters of length-weight relationship, sex ratio, and diet of three freshwater fish species that inhabit streams in the Pomba River basin (Rio de Janeiro, Brazil). Fishes were sampled with seine nets (2.0 × 1.20 m, 2 mm mesh size) and dip nets (0.46 × 0.33 m, 2 mm mesh size) from October to December 2018. Measurements were taken for total length (TL – 0.1 cm precision) and total weight (TW – 0.01 g precision). Growth model parameters were estimated. This study provides new length-weight relationship data for Deuterodon intermedius (Eigenmann, 1908), Australoheros paraibae Ottoni & Costa, 2008, and Hypostomus punctatus Valenciennes, 1840. All of them ingested a wide variety of food items, including plant material like algae, animal material such as terrestrial and aquatic insects, and undefined matter such as detritus or mud. The three species showed a higher number of females. Our study provides basic information for functional diversity studies, as well as for future investigations associated with the evaluation of anthropic impacts, either occasional or chronic, on the fish assemblage structure of the Pomba River basin.
