Peninsula and the western Mediterranean basin. The ancestors of these species are known from fossils that inhabited central Europe in the Pliocene, Numerous previous studies have demonstrated the effect of abrupt climatic oscillations, such as the Quaternary glaciations, on the distribution of animals and plants in Europe. However, the influence of these changes on the ecological requirements of the species is not well known. The published research argues how the historical climate changes that have occurred since the Pliocene, characterized by a general cooling and aridification of the climate in Europe, not only displaced the studied species, but that they were forced to change their ecological preferences in order to adapt and survive to the climate of the new areas in which they were installed. Thus, while the ancestor of these plants had to

escape the progressive cooling of northern Syria Email Lists Europe, An additional consequence was the fragmentation of the ancestor’s distribution area, which eventually induced the speciation of these chaices as their populations were isolated in different regions, originating one species in the western Mediterranean –the Iberian Peninsula, Morocco and Algeria– and another in the central Mediterranean – Sicily, Sardinia and Tunisia. Furthermore, the genetic structure found in both species is strongly determined by geographic barriers such as seas and mountains, supporting the fundamental role of geography in the origin of many species. The study helps to understand and anticipate the effect of future climatic changes on the ecology of the species as part of their adaptation strategies to a changing environment. The question remains whether species will be able to adapt to current climate change,

produced by human activity and taking place at an unprecedented rate.Almost a year ago, researchers Stephen T. Garnett and Christidis defended in an article published in Nature that “the anarchy of taxonomy hinders the conservation of biodiversity” and proposed a more “rational” way to name species. A group of 184 researchers, many of them taxonomists, answer in another article published in PLOS Biology why taxonomy should continue to be based on science and not be subject to legislation. When it is decided to protect a natural space, not only the landscape and the geological substrate are protected, but also the living beings that live there, the species. The problem that Garnett and Christidis pose is that when a species changes its name, the law is no longer applicable. For example, at a certain point in Spain it was decided to prohibit the hunting of native crayfish,
