question to the fi tting of statistical distribution models to P-O datasets (i.e. model calibration; Chefaoui and Lobo 2008, Vanderwal et al. 2009, Barbet-Massin et al. 2012). A fundamental assumption in SDM calibration is the unbiased sampling of available conditions in the environmental space (Araú jo and Guisan 2006, Pearce and Boyce 2006). However, sampling bias is a widespread issue since ...

The Sertoli cell is a highly differentiated somatic cell in the seminiferous epithelium of the testis. This cell is of prime importance for both testicular development and spermatogenesis. Sertoli cells proliferate up to the start of puberty and, due to their nursing functions, the final Sertoli cell number is well correlated to the amount of germ cells produced by the adult testis. The physiol...

Global conservation prioritization often focuses on protecting the most species for the money invested (e.g., Myers et al. 2000; Orme et al. 2005; Wilson et al. 2006). Biodiversity hotspots and surrogate species are heralded as promising approaches for achieving this goal (e.g., Rodrigues et al. 2004; Bani et al. 2006; Lamoreux et al. 2006). Although identifying biodiversity hotspots (Myers et ...
