Rays of the family Rhinopteridae Jordan & Evermann, 1896 are highly migratory and widely distributed in warm tropical and temperate waters. Along the Brazilian coast, the presence of two species has been recorded: Rhinoptera bonasus Mitchill, 1815 and Rhinoptera brasiliensis Müller, 1836. These stingrays are commonly caught as bycatch in trawl fisheries, however, the two species lack distinctive external morphological features...

Angus cattle, originally from Scotland, have been selectively bred for over 400 years, making them one of the most prominent beef breeds globally. Known for their adaptability, natural polled traits, and high-quality beef, Angus cattle have been intensively selected for growth, body size, and feed efficiency. This study investigates the genetic diversity, selection history, and key genomic regions across five Angus populations...

Mitochondrial dysfunction plays a critical role in the development of metabolic dysfunction-associated steatotic liver disease (MASLD). It has been proposed that mitochondrial unfolded-protein response (UPR mt ) activation improves mitochondrial function in the liver. Growing evidence demonstrates that physical exercise effectively prevents and treats MASLD. However, the effects of exercise on UPR mt activation in the liver ar...

Urban wastewater systems represent important interfaces between human activity and the environmental occurrence of antimicrobial resistance (AMR) markers. We assessed the temporal dynamics of intI1 , ermB , and the 16 S rRNA gene by quantitative PCR across three wastewater systems (EPC, CJC, and JW) in Fortaleza, Brazil, from November 2021 to November 2023. Bacterial communities were additionally characterized by 16 S rRNA gen...

Gonatobotryum is an anamorphic fungus reported mainly as a saprophyte, parasite, or endophyte. The genus has traditionally been identified based on morphological features, with its phylogenetic placement remaining uncertain due to the lack of molecular data. During the analysis of fungi obtained from mangrove sediments in Brazil, nine isolates were morphologically identified as Gonatobotryum and subsequently analysed using the...

This study evaluated the effects of providing 3–15 kg of a soluble and biodegradable biopolymer-based enrichment material (blend of biodegradable polymers and natural fibers) to prepartum sows housed in farrowing crates. Fifteen sows were blocked by body weight and backfat thickness and assigned to three treatments: no enrichment material (CONT), 3 kg of enrichment material (BN3), or 15 kg of enrichment material with added nut...

While bats are known to harbor various viruses and bacteria, their role as hosts for hemoparasites has not been extensively studied. This research investigated the presence of ectoparasites and vector-borne pathogens—including Anaplasmataceae agents, hemoplasmas, apicomplexans, and kinetoplastids—in 74 Phyllostomidae bats sampled from an urban forest fragment in southeastern Brazil. Overall, 31.1% of the bats were infested wit...

Eichhornia crassipes (water hyacinth) is among the world’s most aggressive aquatic invasive plants, with severe ecological and socioeconomic impacts on freshwater ecosystems. Over the last two decades, remote sensing has emerged as a critical tool for monitoring its spread and supporting management decisions, offering scalable, repeatable, and increasingly precise assessments. This review synthesizes 56 studies published betwe...

The feeding behavior of the amphicyonid Magericyon anceps from the Batallones-1 fossil site has been investigated so far based on comparative anatomy, which provided a functional hypothesis of this carnivoran as being a capable hunter rather than a scavenger. In this work, we study the feeding behavior of M. anceps under a biomechanical approach using the virtual paleontology toolbox. Our results suggest that M. anceps was wel...
