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...

Potato ( Solanum tuberosum L.) production is expanding in subtropical environments where heat and irregular rainfall constrain yield. This study investigated how seasonal water input patterns and dry spells affect potato growth, yield, and quality when high temperatures occur early and late in the season. We conducted a three-year field experiment in Gujarat (India) in which we compared two irrigation quantities (full, maintai...

Saliva plays a crucial role in oral defense across mammals by combining host-derived antimicrobial factors with antagonistic indigenous microbiota. Understanding the composition of the oral lactic microbiota in wild canids may provide valuable insights into microbial ecology and animal health. In this study, Lactobacillus and Enterococcus spp. isolated from the saliva of South American bush dogs ( Speothos venaticus ) and mane...

Effective stress regulation is essential for emotional health, whereas maladaptive stress responses contribute to neuropsychiatric disorders such as depression and post-traumatic stress disorder. Because neuron–microglia interactions are increasingly recognized as key modulators of neuroplasticity under physiological conditions, stress-related microglial dysregulation may contribute to aberrant neuronal responses implicated in...
