Globally, elasmobranchs have suffered severe population declines and are, therefore, under an urgent necessity of protection, particularly along the Northeastern Atlantic realm. However, a lack of ecological (e.g., abundance) knowledge across this realm limits the implementation of adequate conservation and management actions. Here, we collected 4,...

Sharks play a key role in the structure and functioning of marine ecosystems. More ecological information is essential to implement responsible management and conservation actions on this fauna, particularly at a regional level for threatened species. Mustelus mustelus is widely found in the eastern Atlantic Ocean and catalogued as "Vulnerable" by...

Marine organisms represent nearly half of the worldwide biodiversity; thus, marine macroalgae are known to be good biomonitors of pollution and their ability to accumulate a wide range of pollutants to levels higher than those found in the surrounding waters. These macroalgae species have a unique ability to be used to evaluate metals pollution in...

Aims The present study is the first attempt to grasp the scale and richness of marine biological invasions in Macaronesia. We pioneered a comprehensive non‐native species (NNS), inventory in the region to determine their diversity patterns and native distribution origins. NNS were defined here as the result of both introductions and range expansion...

Aim The influence of niche and neutral mechanisms on the assembly of ecological communities have long been debated. However, we still have a limited knowledge on their relative importance to explain patterns of diversity across latitudinal gradients (LDG). Here, we investigate the extent to which these ecological mechanisms contribute to the LDG of...
