Aims Understanding fine-grain diversity patterns across large spatial extents is fundamental for macroecological research and biodiversity conservation. Using the GrassPlot database, we provide benchmarks of richness values Palaearctic open habitats vascular plants, bryophytes, lichens complete vegetation (i.e., sum former three groups). Location biogeographic realm. Methods We used 126,524 plo...

The Night Heron Nycticorax nycticorax is widespread across the Palaearctic region though its population has decreased during the last century (Cramp & Simmons, 1977). In the Iberian Peninsula it has a threatened status (Blanco & González, 1992) and its reproduction is concentrated in no more than thirty colonies in the North, Northeast and Southwest (Palacios, 1997). Currently, population estim...
