Climate change increasingly influences habitats of often isolated butterflies and moths in nutrient-poor bogs. The insect species are mainly associated with colder local climates, particular edaphic conditions and a specific plant composition. Therefore it is important to have a detailed knowledge of the most sensible species and their demands. Against this background the paper presented differentiates and describes tyrphobiontic and tyrphophilic species of nutrient-poor bogs based on specific parameters. For this purpose criteria such as larval host plants, distribution type, microclimatic preferences and essential bog structures have been applied. Additionally the paper gives an insight into the post-glacial biogeography of Central Europe, including Pleistocene and Holocene migrations of butterfly species. Finally, the study discusses potential threats are discussed and necessary protection measures. © 2015, Naturschutz und Landschaftsplanung. All right reserved. Source

The younger glacial landscape of Mecklenburg-Western Pomerania is characterized by the Vistula glaciation and the subsequent Holocene processes. The great variety of landforms is the result of an attenuation of erosive processes after a long period of forest cover. This is also reflected in the diversity of faunal colonization of streams and ditches. The article provides an overview of the biological communities in selected groups of merolimnic insects of the ditches in Mecklenburg-Western Pomerania. The occurrence of endangered species in ditches of different landforms (fens, outwash plains, ground moraines) is discussed. Source

Case studies of two Natura 2000 Sites in Saxony-Anhalt Climate change represents an additional hazard for many protected species. In the light of the supposed increase in aridity this especially applies to aquatic ecosystems and wetlands. The study presented aimed to analyse the impact of climate change on European protected species based on two Natura 2000 sites in Saxony-Anhalt. In the first step the study assessed the degree and type of climate sensitivity for each species using literature research. On this base the bio-climatic response of the species could be predicted for three periods (2011-2040, 2041-2070, 2071-2100). The comparison between projected climate parameters of the areas analysed and the species-specific climatic envelope allowed to determine whether or not a species might be able to persist in the examined areas regarding each of the three time periods. The results show that in future many of the considered species could suffer from a lack of cold. To minimise the expected impacts of climate change area-specific management strategies are outlined.

In 2010 the assemblages of the Lepidoptera and selected groups of merolimnic insects in the bog "Teufelsmoor near Gresenhorst" were examined. The goal was to conclude by bioindication on ecological deficits. The method of Standorttypieindex, the ecological profiles and preferences of discovered species due to hygrophila and the food plants were used. It was found that the bog still has a high regeneration potential. The habitat deficits mainly lie in a mild disorder of water balance, in the structural deficits of Lagg, in the lack of forest wane and the surrounding coniferous forests. It can be derived proposals for ecological restoration projects. Source

The Entomological Association of Rostock observed different groups of insects in the nature reserve "Schlichtes Moor" in the years 2012 and 2013. This 52 acre area consists of a semi-natural kettle holemire and of large deciduous forests. 97 species of Lepidoptera species were identified, including 2 stenotopic species, bound to bogs. 34 species of Cerambycids could be found. 58% of them live in deciduous wood, 21% in coniferous wood, 18% in deciduous-/coniferous wood and softwood and 3% have their habitat in herbaceous plants. 27 species of Aphids were collected, some of them develop on typical plants of bogs. Especially dragonflies have been found within the benthic invertebrates. Numerous typical bog species are among them. Source
