The major histocompatibility complex (MHC) genes are central to the adaptive immune
response in vertebrates. Selection generally maintains high MHC variation because the …

Morphological and genetic variation of organisms is generally lower in northern than in
southern regions of the Palearctic. This ubiquitous geographical pattern has been …

European marbled newts come in two species that have abutting ranges. The northern
species, Triturus marmoratus, is found in France and the northern part of the Iberian …

Climate and land use/land cover (LULC) change are two major global change factors driving
shifts in the location of suitable areas for many species. Here, we assessed if a low‐vagility …

Theoretical and empirical studies suggest that the structure and position of hybrid zones can
change over time. Evidence for moving hybrid zones has been directly inferred by repeated …

Abstract Natural History Collections (NHCs) represent the world's largest repositories of long-
term biodiversity datasets. Specimen collection and voucher deposition has been the …

Iberian populations of large-bodied newts, with Triturus marmoratus in the north and T.
pygmaeus in the south of the peninsula, were studied for external morphology …

Pond physical characteristics (connectivity, hydroperiod) have shown to be highly relevant in
explaining species presence, reproductive success, and survival in breeding-pond …

Deeply diverged yet hybridizing species provide a system to investigate the final stages of
the speciation process. We study a hybridizing pair of salamander species—the …

Secondary contact between closely related species can lead to the formation of hybrid
zones, allowing for interspecific gene flow. Hybrid zone movement can take place if one of …
