Global warming caurse genetic changes - Research Paper Example These changed seasonal relations are explicable totally as temperature-responsive reactions (McDonald, 2). Climate changes on diverse geographic scales and timescales. Climatic changes monitored over a few decades associates with alterations in living populations and species. Some speculative grounds for anticipating types of climate-driven changes in species and populations that we observe nowadays to play out as hastened speciation over the timeline of thousands or millions of years exist (Barnosky& Kraatz, 3). Global warming is moving at a quicker rate at more northerly latitudes, which is leading to less cold stress caused by extreme winter and longer growing seasons. Species of animals have been enlarging their range toward the limits and populations have been developing, migrating or reproducing earlier over the past 40 years. Phenotypic plasticity or the capability of characters to change their behavior, morphology or physiology in response to modified ecological circumstances have attributed to these developments and changes (Connor, 2). Many species are changing to the lengthened growing season caused by the slight rise in standard global temperatures over the past century. Seeds are sprouting, birds migrating and frogs regenerating earlier. All of these however are not lasting genetic transformations but changes in individual behavior (Nature.com, 1). Numerous studies have indicated connections between climate drifts over the past 50 years or so and changes in population density, in the geographic variety of species or in other parameters that affect the number of offspring produced. Such effects have been monitored in different mammals such as moose, deer, African antelope, bighorn sheep, caribou, musk oxen and foxes. Therefore, it appears likely that climatic changes influence how animals are distributed on
