Background Accurate identification of Sporophila is crucial for conservation and combating trafficking. Due to morphological similarity among females, molecular tools are essential. Although cytochrome c oxidase subunit 1 ( COI ) is the standard animal barcode, its limited resolution in recently diverged species necessitates more informative regions, such as cytochrome b ( CYTB ) and NADH dehydrogenase 2 ( ND2 ), which are eff...

Cory’s Shearwater ( Calonectris borealis ), a migratory seabird from the Procellariidae family, is widely distributed across the Atlantic Ocean. It breeds on islands of Azores, Madeira, Canary, and Berlengas, and winters in coastal areas of South America and Africa. This species’ wide habitat range contributes to pathogen exchange across global regions. Plasmodium , a genus of apicomplexan parasites causing avian malaria, affe...

Marinobufagin (MBG), a cardiotonic steroid from Rhinella toads, exhibits potent antitumor activity. However, their involvement in the mammalian neurotoxicity remains unclear. Therefore, this study evaluated the systemic (neuro)toxicological action of MBG to understand its central effects, particularly those associated with seizure-inducing activity. Initially, physicochemical, pharmacokinetic, and drug-likeness profiles and mo...

Brain cancers hijack biological systems involved in neural development and synaptic plasticity. Medulloblastoma (MB), the most common malignant brain tumor in children, is thought to arise from disruptions in neurodevelopmental programs. Glutamatergic transmission mediated by α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors (AMPARs) has been implicated in synaptic communication between adult brain tumors a...

Wetlands are recognized as important carbon sinks and stocks within the global carbon cycle. However, gaps persist in quantifying and valuing their ecosystem services, particularly under land-use and land-cover (LULC) changes in complex systems such as the Brazilian Pantanal. This study assessed carbon stocks and sequestration in the Pantanal do Abobral subregion using predictive modeling and the economic valuation of ecosyste...
