evolutionarily older than angiosperms. In the fourth case, the pollen comes from water lilies, aquatic plants of the nymphaea family (a very primitive group of angiosperms). “Kateretid beetles initially fed on pollen grains or other plant components of gymnosperms. When the expansion of the angiosperms began, these plants became a new food resource for the beetles, which were able to consume new resources (pollen, nectar and flower petals) “, details David Peris. “Thus,” continues the expert, “these coleopterans quickly adapted to the new resource offered by flowers and favored the beginning of a relationship of mutualism in the pollination process between these insects and angiosperms.” In today’s ecosystems, the pollinating agent of

most gymnosperm plants is wind (anemophilic pollination), Ukraine Phone Number List and in the case of angiosperms, insects (entomophilic pollination). Regarding this evolution of the pollination process in the plant world, “the new work confirms the great evolutionary advantage that the adaptation of beetles to the pollination of angiosperm plants has meant, since nowadays there are no karatetids associated with gymnosperm plants” , conclude David Peris and Xavier Delclòs. A study led by research staff from the Doñana Biological Station (EBD) , center of the Higher Council for Scientific Research (CSIC) in Seville, has found a paradox around the boreal lynx ( Lynx lynx ). Although it is a species with a relatively large population and widely distributed in different geographical

regions of the planet, it presents a very low genetic variability, comparable to endangered species, such as the Apennine brown bear, and only slightly higher than that of the Iberian lynx. The research has recently been published in Molecular Ecology . In the opinion of María Lucena-Pérez , EBD researcher and main author of the study, this paradox is explained “by the fact that the species has suffered a continuous population decline for thousands of years, much more accentuated after the last ice age. , especially in Europe ”. The northern lynx populations that remained genetically homogeneous and relatively abundant until 100,000 years ago, began to reduce their numbers and to contract their range on that date, probably as a consequence of the
