The European Water Framework Directive 2000/60/EC (WFD) defines the ecological status of aquatic systems as the deviation between their present biological state and that which would be expected in the absence of any major ...

Landscape change can expose individuals to rapidly changing conditions, and thus may accelerate phenotypic divergence among populations. However, the spatial scale at which phenotypic change can occur remains poorly ...

Increasing land-use intensification in recent decades has led to the loss and subdivision of large pristine areas, which generally affects species' presence and abundance. However, not every species responds equally to ...

Landscape change provides a suitable framework for investigating population-level responses to novel ecological pressures. However, relatively little attention has been paid to examine the potential influence of landscape ...

We report new distribution data on four recently introduced species in the Guadalquivir River basin: chameleon cichlid (Australoheros facetus Jenyns, 1842), North American black bullhead (Ameiurus melas Rafinesque, 1820), ...
