ABSTRACT The smooth hammerhead shark (Sphyrna zygaena) is a highly migratory pelagic predator classified as Vulnerable due to overexploitation and rapid climate change. However, its genomic diversity, connectivity patterns and demographic history remain poorly understood.

WSMoL attenuates motor impairment, neuroinflammation, oxidative stress, and monoamine depletion in a rotenone‐induced model of Parkinson's disease. The involvement of D1 receptor‐mediated signaling is demonstrated, providing new insights into the mechanisms underlying its neuroprotective effects and supporting WSMoL as a promising candidate for further

Guiana dolphin strandings are spatially concentrated and increasing in Brazil
Guiana dolphins (Sotalia guianensis) serve as critical environmental sentinels, yet they face escalating threats from human activities in coastal and estuarine ecosystems. Despite extensive data collection, integrated assessments of large-scale stranding

ABSTRACT In order to address the many lacunae in Amazonian Piper taxonomy and geography, we performed a field expedition in the Serra do Divisor National Park (Acre state, Brazil), resulting in the discovery of a new species, Piper longiapiculatum, herein described and compared to morphologically similar taxa.

In amberwing dragonfly (Perithemis tenera), solar irradiance in the 550–700 nm range (orange arrows) is only reflected by the colored wings of males (fully orange individuals). Therefore, sunlight intensity may be an important factor driving the effectiveness of their conspicuous wing displays during territorial contests and mating behavior.

Habitat selection plays a crucial role in the survival of various animals, primarily due to their ability to identify suitable sites for development. In Caatinga regions, climate seasonality has a strong effect on vegetation, consequently influencing the occurrence and spatial distribution of diverse plant‐associated organisms.

Fruit colour has long fascinated scientists and is widely considered an evolutionary adaptation to attract both avian and mammalian frugivores. While fleshy fruits play a key role in plant–animal interactions by promoting seed dispersal, the functional significance of colour variation, particularly multicoloured displays during ripening, remains poorly

Guild‐Specific Frog Responses to Natural Habitat Structure Gradients in an Atlantic Forest Mosaic
This study investigated how habitat structure gradients are associated with frog species richness and occupancy in a naturally heterogeneous Atlantic Forest mosaic. We found that frog richness and occupancy patterns varied among ecological guilds and were highest in sites associated with lower values of the habitat structure gradient, which also ...

ABSTRACT Tropical freshwater systems host diverse and functionally important zooplankton communities that are increasingly threatened by multiple stressors. Here, we assessed how land‐use disturbance, local environmental conditions and macrophyte structure influence zooplankton richness, abundance and composition in Amazonian ponds and streams.

ABSTRACT Diplopoda is one of the most diverse terrestrial arthropod groups in Brazil, with the order Spirostreptida Brandt, 1833 standing out for its species richness. Most of the ~180 Brazilian Spirostreptida species occur in the Atlantic Forest, primarily along its coastal region.
