Prewintering Aquatic and Semiaquatic True Bugs in the Timi? River Valley: Adaptations, Diversity, Community Structure and the Role of Antropic Impact

摘要

In November 2011 during a normal overwintering period, a small number of active, aquatic and semiaquatic adult insects were collected from several habitats along the Timi? River basin. This active state for the insects was closely related to higher temperatures found in certain deeper, stagnant water habitats, which also had greater amounts of aquatic vegetation and more stable living conditions. Most such habitats seem to be of anthropic origin, emphasizing the role of human impacts on the life of the discussed group of insects and the need to consider anthropic activities in the conservation of certain species of insects. The state of Aphelocheirus aestivalis is also discussed, along with a proposal to study the species on a larger scale and its possible inclusion on the Romanian Red List.
