The human dimension of biodiversity changes on islands
Nogué, Sandra; Santos, Ana M. C.; Birks, H. John B.; Björck, Svante; Castilla-Beltrán, Alvaro; Connor, Simon; de Boer, Erik J.; Nascimento, Lea deIslands are among the last regions on Earth settled and transformed by human activities, and they provide replicated model systems for analysis of how people affect ecological functions. By analyzing 27 representative fossil pollen sequences encompassing the past 5000 years from islands globally, we quantified the rates of vegetation compositional change before and after human arrival. After human arrival, rate...
Topography-driven isolation, speciation and a global increase of endemism with ...
Steinbauer, Manuel J.; Field, Richard; Grytnes, John-Arvid; Trigas, Panayiotis; Ah-Peng, Claudine; Attorre, Fabio; Birks, H. John B.AIM: Higher-elevation areas on islands and continental mountains tend to be separated by longer distances, predicting higher endemism at higher elevations; our study is the first to test the generality of the predicted pattern. We also compare it empirically with contrasting expectations from hypotheses invoking higher speciation with area, temperature and species richness. Location Thirty-two insular and 18 co...
