Article
Aim The realised niches of species change following environmental and distributional shifts. Still, the magnitude of niche change and its consequences are determined by how different species cope with environmental changes, which ultimately depends on their ecology and traits. We assessed how environmental and distributional shifts have led to chan...

In interdisciplinary fields such as biodiversity conservation or invasion science-where multiple perspectives from diverse disciplines often need to converge for effective environmental management, it is crucial to minimise terminological confusion in order to understand and transmit concepts accurately. The diversity of perspectives can exert a su...
Article
Full-text available
Conservation is prioritized based on accepted taxa. As a consequence, a conservation incentive exists to emphasize inter‐population differences to define taxa, potentially leading to taxonomic inflation. But stressing the uniqueness of threatened populations has the side effect of hindering conservation actions that promote inter‐population gene fl...
Article
Full-text available
Upstream migration of the Atlantic blue crab Callinectes sapidus is well described in its native range, but it is little known in invaded areas. Here, we report several long‐distance migration events of the blue crab in the Iberian Peninsula and use a global database to calculate the probability of occurrence of the species in relation to distance...
Article
Full-text available
Wildlife roadkill studies need to cope with a mismatch among recorded carcasses and actual road mortality, because of the existence of three biases: crippling, carcass‐persistence, and observer bias. Here, we focused on the often overlooked crippling bias, suggesting that it should be called carcass‐location bias and disentangling the related three...
