Quantification and modelling of the occurrence and distribution of haematophagous arthropods and their roles as potential vectors in various kinds of Landscapesstructures in northeastern Germany with special reference to small water bodies (kettle holes/ Sölle)
Project
Project code: ZALF-819
Contract period: 01.11.2013
- 31.10.2016
Purpose of research: Inventory & Assessment
In the present cross-sectional project, breeding habitats of haematophagous arthropods will be analysed, and the colonization status, the species spectrum, the distribution of the species and the interactions between these species assessed and characterized. Mosquitoes and biting midges are totally dependent on the water balance of their breeding habitats and also depend on the water quality which is influenced by anthropogenic factors. Based on existing data on haematophagous nematocerans from databases (e.g. Culbase, Mückenatlas), collection sites of the various species will be analyzed and classified regarding landscape structures, in addition to entomological field studies. Correlations between landscape structures, the occurrence of haematophagous arthropods and their infection prevalences with pathogens will be verified by further studies and be used as a baseline for modelling approaches. In a first step, selected small water bodies such as ponds (Sölle) and their variations on agricultural floor spaces in MV and BRB will be analysed. The cross-sectional project started in 2013 with a pilot study which will be expanded in 2014 in collaboration with various ZALF institutes (LSA, LWH, LSE) and the Institute for Infectology of the Federal Research Institute for Animal Health/Friedrich-Loeffler-Institut (FLI). The expertise of the partners in the fields of landscape ecology and landscape structure research, water ecology, entomology, molecular taxonomy and diagnostics as well as of spatial explicit modelling is intended to enable the examination of the population dynamics of the blood-feeding arthropods, their interactions with other species of the habitat and key factors of the habitats and landscape parameters from different perspectives. This interdisciplinary approach is meant to help to better describe the factors influencing the establishment, the development and the spread of pest and vector species in landscapes rich of small water bodies.
