Geographic and Biological Drivers Shape Anthropogenic Extinctions in the Macaronesian Vascular Flora.

Whether species extinctions have accelerated during the Anthropocene and the extent to which certain species are more susceptible to extinction due to their ecological preferences and intrinsic biological traits are among the most pressing questions in conservation biology. Assessing extinction rates is, however, challenging, as best exemplified by the phenomenon of 'dark extinctions': the loss of species that disappear before they are even formally described. These issues are particularly problematic in oceanic islands, where species exhibit high rates of endemism and unique biological traits but are also among the most vulnerable to extinction.

A new species of woodlouse (Isopoda, Oniscidea) from the Canarian laurel forest.

A new species of terrestrial isopod, Orihuela-Rivero, of the family Porcellionidae (Oniscidea), is described from the laurel forest of Tenerife, Canary Islands. This new species belongs to the Atlantic group ("") as defined by Vandel due to the structure of the male pleopod 1 and its "primitive" glandular system. Some diag-nostic characters that allow it to be differentiated from other species are revealed, such as (i) the smooth dorsal surface, (ii) the sinuosity of the posterior margin of the first pereonites, (iii) the configuration of the glandular system, and (iv) the structure of the male pleopod 1 exopod.
