Snakebite envenomation is a neglected tropical disease and incidents of the pit viper Lachesis muta cause hemorrhage, muscle damage, blood coagulation disturbances, and even death; the proteases and phospholipase A 2 (PLA 2 ) of snake venoms contribute to such toxic effects. This work evaluated the inhibitory effect of commercial fucoidans from two species of brown seaweeds Fucus vesiculosus (FVF) and Undaria pinnatifida (UPF)...

Reef fish assemblages on oceanic islands offer valuable insights into ecological and evolutionary processes, yet their temporal dynamics remain poorly understood. This study evaluates the theory of island biogeography (TIB) with long‐term ecological monitoring to assess how island area, isolation from nearest reef and distance from mainland shape both species richness and stability across four southwestern Atlantic islands. Da...

Understanding the mechanisms underlying fast diversifications is central to evolutionary biology. This can be partly achieved by focusing on intrinsic reproductive barriers that emerge during early stages of divergence in fast‐radiating groups. Here, we explored the mechanisms underlying the divergence of two ecotypes of the Dianthus rupicola complex, which belong to the Eurasian clade of the hyperdiverse genus Dianthus , the...

Pharmaceuticals are increasingly detected in surface water, and even at trace concentrations, they may pose ecological and health risks. In this study, heterogeneous photocatalysis using titanium dioxide (TiO 2 ) was applied under simulated solar irradiation to degrade sodium diclofenac. Irradiation times of 60, 120, and 180 min were used with a TiO 2 loading of 0.6 g L −1 . Under these conditions, only ~ 20% diclofenac degrad...

Model organisms are species selected for studies due to characteristics that make them ideal for research purposes. These species are chosen for their suitability for scientific investigations. For ecological and evolutionary studies, good model organisms typically exhibit the following characteristics: (1) small genome size; (2) rapid reproductive cycle; and (3) easy manipulation. A small genome size is important for quicker...

Under the current global biodiversity crisis, there is a need for automated and noninvasive monitoring techniques that can gather large amounts of data cost‐effectively at various ecological scales, from local to large spatial scales. These data can then be analyzed to inform stakeholders and decision‐makers. One such technique is passive acoustic monitoring, which is commonly coupled with automatic identification of animal sp...

The south American silver croaker, Plagioscion squamosissimus , holds significant importance for the artisanal fisheries in the sub‐middle and lower courses of the São Francisco River, located in northeastern Brazil. To investigate the population structure of this species along its longitudinal profile, a total of 150 individuals (50 fish per site), measuring between 35 and 45 cm in standard length, were collected from three f...
