Yet, the extent to which global environmental changes contribute to changes in local diversity is poorly understood. We investigated biodiversity changes in a meta-analysis of 39 resurvey studies in European temperate forests (3988 vegetation records in total, 17-75years between the two surveys) by assessing the importance of (i) coarse-resolution (i.e., among sites) vs. fine-resolution (i.e., within sites) environmental differences and (ii) changing environmental conditions between surveys. Our results clarify the mechanisms underlying the direction and magnitude of local-scale biodiversity changes. While not detecting any net local diversity loss, we observed considerable among-site variation, partly explained by temporal changes in light availability (a local driver) and density of large herbivores (a regional driver). Furthermore, strong evidence was found that presurvey levels of nitrogen deposition determined subsequent diversity changes. We conclude that models forecasting future biodiversity changes should consider coarse-resolution environmental changes, account for differences in baseline environmental conditions and for local changes in fine-resolution environmental conditions.}, language = {en} } @book{BauerMarkmannWiegetal.2014, author = {Bauer, Hartmut and Markmann, Friedrich and Wieg, Andreas and George, Wolfgang and Bezzenberger, Tilman and Amschler, Helmut and Henke, Klaus-Dirk and Podtschaske, Beatrice and Klipp, Matthias and Wandersleb, Michael}, title = {Kommunen, B{\"u}rger, Wirtschaft im solidarischen Miteinander von Genossenschaften}, editor = {Bauer, Hartmut and B{\"u}chner, Christiane and Markmann, Friedrich}, publisher = {Universit{\"a}tsverlag Potsdam}, address = {Potsdam}, isbn = {978-3-86956-287-2}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-69713}, publisher = {Universit{\"a}t Potsdam}, pages = {184}, year = {2014}, abstract = {Genossenschaften wirken auf manche wie ein angestaubtes Relikt aus der Vergangenheit. Das eingetr{\"u}bte Image {\"u}berrascht. Denn Genossenschaften haben sich immer wieder als besonders krisenfest erwiesen und l{\"a}ngst auch als erfolgreiches Zukunftsmodell entpuppt. Der stetige Zuwachs an Neugr{\"u}ndungen, die steigenden Mitgliederzahlen und die st{\"a}ndige Ausweitung der Aktionsfelder best{\"a}tigen die hohe Attraktivit{\"a}t. Dem entspricht eine enorme Einsatzbreite der Genossenschaftsidee. Sie reicht von Agrargenossenschaften {\"u}ber Produktionsgenossenschaften in Handel, Handwerk und Gewerbe bis hin zu sehr modernen Bereichen etwa der neuen Informations- und Kommunikationstechnologien. In all diesen und vielen anderen Segmenten finden sich variantenreiche genossenschaftliche Gestaltungsoptionen nach Maximen wie Selbsthilfe, Solidarit{\"a}t, B{\"u}rgerengagement, Partizipation, Mitglieder- und Gemeinwohlorientierung. Inzwischen lockt die hohe Anziehungskraft der Genossenschaftsidee auch die Kommunen. Angestoßen durch gesetzgeberische Impulse erleben die Genossenschaften auf der kommunalen Ebene derzeit bundesweit einen richtigen Aufschwung. Die Aufwertung erweitert die {\"U}berlegungen zur Gew{\"a}hrleistung und Optimierung kommunaler Leistungserbringung um eine wichtige Gestaltungsvariante, nimmt aber den Kommunen die Auswahlentscheidung nicht ab. Denn wie bei allen Organisationsentscheidungen ist vor dem R{\"u}ckgriff auf genossenschaftliche Organisationsformen in jedem Einzelfall eine n{\"u}chterne aufgaben-, sach- und situationsbezogene Vergleichsanalyse geboten, die den Entscheidungstr{\"a}gern spezifische Kenntnisse und detaillierte Fachkompetenz abverlangt.

Using a unique GPS-tracking database of 803 individuals across 57 species, we found that movements of mammals in areas with a comparatively high human footprint were on average one-half to one-third the extent of their movements in areas with a low human footprint. We attribute this reduction to behavioral changes of individual animals and to the exclusion of species with long-range movements from areas with higher human impact. Global loss of vagility alters a key ecological trait of animals that affects not only population persistence but also ecosystem processes such as predator-prey interactions, nutrient cycling, and disease transmission.}, language = {en} }
