Paleoclimatic models suggested a high instability of the range of this lineage in the last 3 Mya, with niche contractions during the colder glacial periods and expansions following the glacier retreat. This suggested an allopatric diversification process, with subspecies boundaries upon secondary contact maintained by competitive interactions, at least between closely related pairs. The great mountain systems of the Mediterranean Peninsulas constituted stable refugia during the Pliocene–Pleistocene cycles, favouring the evolution of endemic subclades.  Leer más.

Here, the gradual deterioration of one of the network’s main ponds is described in detail by characterizing vegetation patterns within the pond’s basin using orthophotos taken between 1956 and 2019. Leer más.

Comprehending how changing environmental conditions are affecting species and ecosystems is essential for well-informed conservation planning. Especially since changes at minor spatial scales could be happening rapidly, substantial fieldwork efforts are necessary to detect novel behaviours and their consequences. Leer más.
