Endemic Species have highly integrated phenotypes, environmental distributions and phenotype–environment relationships
Journal of Biogeography, 2013Co-Authors: Marie Hermant, Andreas Prinzing, Philippe Vernon, Peter Convey, Françoise HennionAbstract:Keywords: Abiotic environmental gradients; endemism level; functional biogeography; island biogeography; Kerguelen Islands; life-history traits; multi-Species comparison; phenotypic integration; range size; sub-Antarctic Abstract Aim: Why are some Species geographically restricted? Ecological explanations suggest that Endemic Species may have restricted distributions because limited phenotypic variability results in narrow niches. However, studying variability of traits independently may not fully explain the interactions within and between complex phenotypes and environments. Here, we hypothesize that Endemic Species are restricted to a narrow range of habitats due to strong phenotypic integration (i.e. strong correlations among traits), strong environmental integration (i.e. strong correlations among the environments occupied) and strong correlations among trait–environment combinations. Location: The Kerguelen Islands, sub-Antarctic. Methods: We measured flowering phenology, multiple morphological characters, and Species distribution along three abiotic environmental gradients (elevation, soil moisture and soil salinity) in 14 plant Species whose distributions range from strictly Endemic to cosmopolitan. Results: We found that for individual Species, trait means and variances were independent of endemism, but that Endemics occupied higher and less variable microhabitats. However, phenotypic integration, environmental integration along the three gradients, and the strength of trait–environment correlations all increased with the level of Species endemism. Main conclusions: Higher levels of integration within and between phenotypes and environments are associated with more restricted geographical ranges in the Species studied. In Endemic Species phenotypic integration may explain range contraction during the taxon cycle and reduce the ability to adapt to novel microhabitats formed as a result of environmental change.

Elymus sosnowskyi (Hackel) Melderis (Poaceae), a rare Endemic Species in Turkey
Turkish Journal of Botany, 2010Co-Authors: Evren Cabi, Musa Doğan, Özlem Mavi, Ersin Karabacak, Birol BaşerAbstract:Elymus sosnowskyi, a rare Endemic Species known from East Anatolia, Turkey, was first collected by D. Sosnowsky in 1912. After that it has been collected only one other time, by F. Sorger in 1981. During the "Taxonomic revision of tribe Triticeae in Turkey" project, which was supported by TUBITAK, E. sosnowskyi was recollected from 3 populations in Oltu and Narman (A8 Erzurum, Turkey) in 2007 and 2008. The present study aimed to provide detailed diagnostic characters of this rare Endemic Species, including its morphological, anatomical, and palynological features. Moreover, the amended and expanded description, distribution, phenology, and ecology of this rare Species are provided, along with its conservation status.
