In mountain ecosystems, the persistence of species increasingly depends on the maintenance of functional connectivity under the dual pressures of climate and land‐use change. “Sky island” species such as the mountain hare ( Lepus timidus ) are particularly vulnerable, being restricted to high‐altitude cold‐climate habitats. Meanwhile, generalist and expanding species like the European hare ( L. europaeus ) may further threaten...

To improve understanding of bull shark Carcharhinus leucas reproductive biology, we analysed reproductive traits from 118 bull sharks caught along Reunion Island coasts (Western Indian Ocean), including 16 gravid females. Specific microsatellite loci were used to investigate the frequency of multiple paternity. Males and females reached maturity at c . 234 cm and 257 cm total length ( L T ), respectively, and litter sizes rang...
