Aim: The ‘abundant center’ hypothesis states that species are more abundant at the center of their range. However, several recent large-scale studies have failed to find evidence for such a pattern. Here we use extensive global data of reef fishes to test the strength of the 'abundant center' pattern, and to examine variation in the patterns across species using life history and ecological traits. Location: Marine habitat at a global extent: from Indo-Pacific to Atlantic...

Describing spatial variation in species richness and understanding its links to ecological mechanisms are complementary approaches for explaining geographical patterns of richness. The study of elevational gradients holds enormous potential for understanding the factors underlying global diversity. This paper investigates the pattern of species richness and range-size distribution of epiphytic bryophytes along an elevational gradient in Marojejy National Park, North-east Madagascar. The main objectives are to describe bryophyte species composition and endemism in Marojejy National...
