It is known, that red deer are differently distributed in human disturbed areas compared to areas with less anthropogenic influences. But knowledge about the potential influence of human presence on social associations and interactions is rare, albeit differences may result in changing impacts on the environment, such as habitat utilization and feeding damage. Therefore, we investigated differences in the space use and social association of red deer. We studied two radio-collared herds of non-migratory populations in two study areas, which were comparable in landscape structure and vegetation structure, but differed in accessibility for visitors and the extent of their presence. Between the two study sites we compared the home range size, the differences in the extent of home range overlap within each study site and the space-time association (Jacobs Index) of individuals. Additionally, we present data on seasonal variations of home range sizes and social association all year round. In order to compare human activity in the study sites, we used the data from our long-term camera trap monitoring. The herd in the area with more human activity had significantly smaller home ranges and had greater year-round social associations in almost all seasons, except summer. We assume that smaller home ranges and higher association between animals may result in a higher feeding pressure on plants and a patchier utilization in areas with higher disturbances.}, language = {en} } @article{WeissMichlerGillichetal.2022, author = {Weiss, Fabio and Michler, Frank Uwe and Gillich, Benjamin and Tillmann, J{\"o}rg and Ciuti, Simone and Heurich, Marco and Rieger, Siegfried}, title = {Displacement Effects of Conservation Grazing on Red Deer (Cervus elaphus) Spatial Behaviour}, series = {Environmental Management}, volume = {70}, journal = {Environmental Management}, publisher = {Springer Nature}, issn = {0364-152X}, doi = {10.1007/s00267-022-01697-6}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-4609}, pages = {763 -- 779}, year = {2022}, abstract = {Conservation grazing uses semi-feral or domesticated herbivores to limit encroachment in open areas and to promote biodiversity. However, we are still unaware of its effects on wild herbivores. This study investigates the influence of herded sheep and goats on red deer (Cervus elaphus) spatial behavior by testing three a-priori hypotheses: (i) red deer are expected to avoid areas used by livestock, as well as adjacent areas, when livestock are present, albeit (ii) red deer increase the use of these areas when sheep and goats are temporarily absent and (iii) there is a time-lagged disruption in red deer spatial behavior when conservation grazing practice ends. Using GPS-telemetry data on red deer from a German heathland area, we modelled their use of areas grazed by sheep and goats, using mixed-effect logistic regression. Additionally, we developed seasonal resource selection functions (use-availability design) to depict habitat selection by red deer before, during, and after conservation grazing. Red deer used areas less during conservation grazing throughout all times of the day and there was no compensatory use during nighttime. This effect mostly persisted within 21 days after conservation grazing. Effects on habitat selection of red deer were detectable up to 3000 meters away from the conservation grazing sites, with no signs of either habituation or adaption. For the first time, we demonstrate that conservation grazing can affect the spatio-temporal behavior of wild herbivores.

Whether wild large herbivores, such as red deer (Cervus elaphus), benefit from the management of the open landscapes is unknown, and there are conflicting views on the nature of the interaction between livestock and wildlife. To investigate this question, we studied interactions in space and time between red deer and livestock in an 787 ha fenced pasture in eastern Germany. First, we used faecal pellet counts to determine whether red deer were using the fenced pasture and whether livestock were using the entire available pasture. Second, we fitted ten red deer, as well as eight Konik horses (Equus ferus caballus) and eight Heck cattle (Bos taurus) with GPS-collars. These data allowed us to perform analyses of space-time interactions. The faecal pellet data showed that red deer did indeed use the fenced pasture and that livestock used the entire extent of the pasture. Further, we verified a neutral space-time interaction between red deer and livestock within the pasture. Thus, there was no indication of a negative effect of the presence of livestock on red deer inside the pasture. For these reasons, we recommend that low-intensity grazing by cattle and horses can maintain open landscapes without detrimental effects on the use of the area by red deer.}, language = {en} } @article{BerndtEdingerSchulzetal.2021, author = {Berndt, Carolin and Edinger, Nadin and Schulz, Ulrich and Rieger, Siegfried and Gillich, Benjamin and Michler, Frank-Uwe}, title = {Erste Schritte eines Heimkehrers - Raumnutzung eines besenderten Elches (Alces alces L., 1758) in Brandenburg und Sachsen-Anhalt}, series = {S{\"a}ugetierkundliche Informationen}, volume = {12}, journal = {S{\"a}ugetierkundliche Informationen}, number = {58}, publisher = {Arbeitsgruppe Artenschutz Th{\"u}ringen e.V.}, issn = {0323-8563}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-6508}, pages = {25 -- 50}, year = {2021}, language = {de} } @inproceedings{MichlerEdingerGillichetal.2022, author = {Michler, Frank-Uwe and Edinger, Nadin and Gillich, Benjamin and Rieger, Siegfried}, title = {Raumverhalten sendermarkierter W{\"o}lfe (Canis lupus) in Ostdeutschland}, series = {Wildtierforschung im 21.
