The presence or absence of a fish species may be associated with the physical and chemical characteristics water, in addition to state preservation riparian zone. This study examined whether taxonomic composition an urban river varies along three zone conditions: preserved, intermediate degraded. Six stretches Sorocaba/São Paulo River were selected for this study, monthly sampling being carried...

Invasive alien species (IAS) are a leading driver of biodiversity loss worldwide, and have negative impacts on human societies. In most countries, available data monetary costs IAS scarce, while being crucial for developing efficient management. this study, we use collected from the first global assessment economic (InvaCost) to quantify describe cost invasions in Mexico. This description was m...

Despite being considered friendlier to the environment, biodiesel fuel can be harmful to aquatic organisms, especially when combined with petroleum diesel fuel. In this work we evaluated the effects of mineral diesel fuel containing increasing concentrations of biodiesel (5% and 20%, namely B5 and B20) and pure biodiesel (B100), at concentrations of 0.001 and 0.01mLL(-1), after 15 days of expos...

The study of ichthyoplankton composition, abundance and distribution is paramount to understand the reproductive dynamics local fish assemblages. analysis these parameters allows identification spawning sites, nursery areas migration routes. However, due lack characters in early life stages, morphological often impractical many studies identify only larvae. Additionally, its accuracy shows grea...

Comprendre les facteurs responsables du succès des espèces exotiques est une question de recherche centrale en biologie invasions. Les caractéristiques écologiques jouent un rôle indéniable dans la réussite l’invasion, mais le lien entre traits et différentes dimensions l'invasion reste encore à étudier chez vertébrés. Nous ...
