Despite their importance for plant health and growth, the response of these bacteria to grassland management regimes is still not understood. Hence, we investigated the bacterial community structure in three agricultural important grass species Dactylis glomerata L., Festuca rubra L. and Lolium perenne L. with regard to fertilizer application and different mowing frequencies. For this purpose, above-ground plant material was collected from the Grassland Management Experiment (GrassMan) in Germany in September 2010 and 2011. DNA was extracted from surface-sterilized plant tissue and subjected to 16S rRNA gene PCRs. Endophytic community structures were assessed by denaturing gradient gel electrophoresis (DGGE)-based analysis of obtained PCR products. DGGE fingerprints revealed that fertilizer application significantly altered the endophytic communities in L.perenne and F.rubra but not in D.glomerata. Although no direct effect of mowing was observed, mowing frequencies in combination with fertilizer application had a significant impact on endophyte bacterial community structures. However, this effect was not observed for all three grass species in both years. Therefore, our results showed that management regimes changed the bacterial endophyte communities, but this effect was plant-specific and varied over time. Significance and Impact of the StudyEndophytic bacteria play an important role in plant health and growth. However, studies addressing the influence of grassland management regimes on these bacteria in above-ground plant parts are still missing. In this study, we present first evidence that fertilizer application significantly impacted bacterial community structures in three agricultural important grass species, whereas mowing had only a minor effect. Moreover, this effect was plant-specific and thus not visible for all grass species in each year. Consequently, this study sheds new light into the complex interaction of microbes and plants."],["dc.identifier.doi","10.1111/lam.12551"],["dc.identifier.isi","000373000600005"],["dc.identifier.pmid","26834040"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/41042"],["dc.language.iso","en"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","1472-765X"],["dc.relation.issn","0266-8254"],["dc.title","Impact of grassland management regimes on bacterial endophyte diversity differs with grass species"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]

The special conditions are the basis for a comparatively large population of red deer. The framework for forestry and hunting is laid by both the landscape structure and the military training on the grounds. While the habitat is highly suitable for red deer, a stable, protective forest, as well as cost-efficient forestry, are also of importance in large parts of the area. Therefore, goal-oriented management of red deer is of high operational importance for the Bundes¬forstbetrieb (Federal Forest Administration). In order to meet goals in forestry, the reduction of the influence of red deer on the forest vegetation is essential. Unlike in a man-made environment, the red deer are able to use vast swaths of their haunt during the entire day due to the ab¬sence of disturbances. This provides a number of starting points for the management of red deer in respect to their habitat. For quite some time the Federal Forest Adminis¬tration has attempted to direct the population on the ba¬sis of the animals’ positive and negative experiences. This project aimed to evaluate this system, as well as to provide starting points for further development. For this purpose 29 red deer of both sexes in the Gra¬fenwöhr military training area were equipped with GPS transmitters from 2008 to 2010. In addition to the GPS-units, the col¬lars contained activity sensors that detected the in¬tensity of movement. The data makes it possible to distinguish between phases of movement and phases of resting. The animals were captured and immobili¬sed in corrals or with a dart gun from a blind. The transmitters showed quite different operating times. In some cases the transmission time was re¬duced by damage or mortality. On the whole, 17 ani¬mals (7 stags, 10 hinds) provided fully evaluable sets of data with an operating time of more than a year. As an additional reference, data from telemetry pro¬jects from Schleswig-Holstein (an intensively used and highly fragmented cultural landscape) and the Kellerwald-Edersee National Park (conservation area, common beech forest) were available."],["dc.format.extent","152"],["dc.identifier.isbn","978-3-940232-07-6"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/62227"],["dc.language.iso","de"],["dc.publisher","Verlag Frank Fornacon"],["dc.publisher.place","Ahnatal"],["dc.title","Vom Wald ins Offenland – der Rothirsch auf dem Truppenübungsplatz Grafenwöhr: Raum-Zeit-Verhalten, Lebensraumnutzung, Management"],["dc.type","book"],["dc.type.internalPublication","unknown"],["dspace.entity.type","Publication"]]

Despite the importance of the home range concept, there is no consensus on how to estimate the HRS of animals. Assessments of the performance of commonly applied HRS estimators have largely been based on simulated data or on location data of few sample individuals occupying one study area. To empirically evaluate the impact of supplementary feeding, habitat composition, red deer sex, and estimation method (minimum convex polygon (MCP), kernel density estimator (KDE) and alpha-local convex hull (alpha-LoCoH)) on HRS, we analysed the data of 183 annual red deer home ranges using a mixed modelling approach. Red deer HRSs were smallest in areas with substantial supplementary feeding, intermediate in areas with closed forest cover but no supplementary feeding, and largest in fragmented landscapes where supplementary feeding rarely occurs. Consistently, male HRSs were larger than female HRSs. While MCP- and KDE-HRS estimates were roughly similar, estimates from the alpha-LoCoH method were substantially smaller than those of MCP and KDE. Analyses of 342 seasonal HRS largely reflected patterns of annual HRS. However, seasonal HRS differed between seasons and red deer sex. In areas with no or little feeding, red deer adjusted HRS seasonally, whereas red deer supplied with supplementary food during winter did not alter their HRS seasonally. Our study suggests that supplementary feeding and habitat configuration strongly affect the spatial ecology of red deer; this might have considerable sanitary and ecological implications. We suggest that sex differences in annual space use extent are proportional along a resource gradient but are mediated by seasons. Finally, method-related variation in space use studies of animals needs to be considered more cautiously."],["dc.identifier.doi","10.1007/s10344-013-0772-1"],["dc.identifier.isi","000332759700010"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/33911"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","1439-0574"],["dc.relation.issn","1612-4642"],["dc.relation.orgunit","Abteilung Wildtierwissenschaften"],["dc.title","Home range size estimates of red deer in Germany: environmental, individual and methodological correlates"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]

Hiking is a popular form of outdoor recreation in many countries, including Germany. In this study, we investigate the effects of hiking and hiking trails on space-use dynamics in GPS-collared red deer Cervus elaphus inhabiting the Kellerwald-Edersee National Park, Germany. Specifically, we 1\\) experimentally assess the reactions of red deer to hiker on- and off-trail and 2\\) quantify the effects of hiking trails on daily space-use patterns of the deer. We found that red deer in the Kellerwald-Edersee National Park did not show a spatiotemporal reaction to recreational on-trail hiking, but were sensitive to off-trail hiking that always induced flight of the animals. With increasing trail densities, the flight initiation distance decreased, while the distance moved during a flight was similar across trail densities. Together, these results suggest that the sensitivity to off-trail hiking increases in areas with low trail density, but that the flight reaction, once induced, is uniform. We further demonstrate that red deer avoid hiking trails during the day, but not during nighttime, and that a negative relationship exists between the distance the animals keep to trails and the trail density in an individual home range. Our results indicate that off-trail hiking has the potential to disturb red deer in the Kellerwald- Edersee National Park, but that red deer are able to cope with recreational activity on trails as well as with the presence of trails in general. Our findings underline the importance of hiking rules, such as staying on trails, and visitor management focusing on minimizing conflicts between wildlife and human recreation."],["dc.identifier.doi","10.2981/wlb.00403"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/15828"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/59673"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation.issn","0909-6396"],["dc.relation.orgunit","Abteilung Wildtierwissenschaften"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.subject.ddc","570"],["dc.title","Stay on trails – effects of human recreation on the spatiotemporal behavior of red deer Cervus elaphus in a German national park"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"],["local.message.claim","2021-10-06T08:18:57.112+0000|||rp114797|||submit_approve|||dc_contributor_author|||None"]]
