  abstract  = {Genetic studies of the Eurasian brown bear (Ursus arctos) have so far focused on populations from Europe and North America, although the largest distribution area of brown bears is in Asia. In this study, we reveal population genetic parameters for the brown bear population inhabiting the Grand Ka{\c{c}}kar Mountains (GKM) in the north east of Turkey, western Lesser Caucasus. Using both hair (N = 147) and tissue samples (N = 7) collected between 2008 and 2014, we found substantial levels of genetic variation (10 microsatellite loci). Bear samples (hair) taken from rubbing trees worked better for genotyping than those from power poles, regardless of the year collected. Genotyping also revealed that bears moved between habitat patches, despite ongoing massive habitat alterations and the creation of large water reservoirs. This population has the potential to serve as a genetic reserve for future reintroductions in the Middle East. Due to the importance of the GKM population for on-going and future conservation actions, the impacts of habitat alterations in the region ought to be minimized; e.g., by establishing green bridges or corridors over reservoirs and major roads to maintain habitat connectivity and gene flow among populations in the Lesser Caucasus.},

  abstract  = {Due to continuously intensifying human usage of the marine environment worldwide ranging cetaceans face an increasing number of threats. Besides whaling, overfishing and by-catch, new technical developments increase the water and noise pollution, which can negatively affect marine species. Cetaceans are especially prone to these influences, being at the top of the food chain and therefore accumulating toxins and contaminants. Furthermore, they are extremely noise sensitive due to their highly developed hearing sense and echolocation ability. As a result, several cetacean species were brought to extinction during the last century or are now classified as critically endangered. This work focuses on two odontocetes. It applies and compares different molecular methods for inference of population status and adaptation, with implications for conservation. The worldwide distributed sperm whale (Physeter macrocephalus) shows a matrilineal population structure with predominant male dispersal. A recently stranded group of male sperm whales provided a unique opportunity to investigate male grouping for the first time. Based on the mitochondrial control region, I was able to infer that male bachelor groups comprise multiple matrilines, hence derive from different social groups, and that they represent the genetic variability of the entire North Atlantic. The harbor porpoise (Phocoena phocoena) occurs only in the northern hemisphere. By being small and occurring mostly in coastal habitats it is especially prone to human disturbance. Since some subspecies and subpopulations are critically endangered, it is important to generate and provide genetic markers with high resolution to facilitate population assignment and subsequent protection measurements. Here, I provide the first harbour porpoise whole genome, in high quality and including a draft annotation. Using it for mapping ddRAD seq data, I identify genome wide SNPs and, together with a fragment of the mitochondrial control region, inferred the population structure of its North Atlantic distribution range. The Belt Sea harbors a distinct subpopulation oppose to the North Atlantic, with a transition zone in the Kattegat. Within the North Atlantic I could detect subtle genetic differentiation between western (Canada-Iceland) and eastern (North Sea) regions, with support for a German North Sea breading ground around the Isle of Sylt. Further, I was able to detect six outlier loci which show isolation by distance across the investigated sampling areas. In employing different markers, I could show that single maker systems as well as genome wide data can unravel new information about population affinities of odontocetes. Genome wide data can facilitate investigation of adaptations and evolutionary history of the species and its populations. Moreover, they facilitate population genetic investigations, providing a high resolution, and hence allowing for detection of subtle population structuring especially important for highly mobile cetaceans.},

Die Basis f{\"u}r solche {\"O}kosysteme bilden intakte {\"o}kologische Wechselwirkungen zwischen einer Vielzahl von Arten. Durch den beispiellosen Verlust der Biodiversit{\"a}t, welcher durch die in der zweiten H{\"a}lfte des 20. Jahrhunderts zunehmende Intensivierung der Agrarwirtschaft und die Zerst{\"o}rung und Fragmentierung von Habitaten hervorgerufen wurde, k{\"o}nnen {\"o}kologische Wechselwirkungen und damit die Funktionsf{\"a}higkeit von Agrar{\"o}kosystemen stark eingeschr{\"a}nkt werden. Um den R{\"u}ckgang der Biodiversit{\"a}t in Agrar{\"o}kosystemen abschw{\"a}chen zu k{\"o}nnen, m{\"u}ssen wir die {\"o}kologischen Wechselwirkungen in Agrar{\"o}kosystemen besser verstehen. Hierbei spielen Flederm{\"a}use eine besondere Rolle, weil sie verschiedenste {\"o}kologische Nischen besetzen und eine Reihe von {\"O}kosystemleistungen erf{\"u}llen so wie z.B. die Kontrolle von Sch{\"a}dlingspopulationen in Agrarlandschaften. {\"U}berdies tr{\"a}gt die Ordnung der Flederm{\"a}use (Chiroptera) betr{\"a}chtlich zur globalen Diversit{\"a}t der S{\"a}ugetiere bei. Obwohl viele Fledermauspopulationen durch die Intensivierung der Agrarwirtschaft dezimiert wurden, ist noch relativ wenig dar{\"u}ber bekannt wie unterschiedliche Fledermausarten die offene Agrarlandschaft nutzen. Dieses Wissen ist jedoch essenziell f{\"u}r den Schutz von Fledermausarten in intensiv bewirtschafteten Agrarlandschaften und dringend notwendig besonders vor dem Hintergrund der vorhergesagten erweiterten Ausweitung der intensiven Agrarwirtschaft. Zus{\"a}tzlich werden Flederm{\"a}use durch den zuletzt massiven Ausbau von Windkraftanlagen, welche f{\"u}r viele Vogel- und Fledermausarten ein erh{\"o}htes T{\"o}tungsrisiko darstellen, bedroht. Das Ziel dieser Dissertation war es deshalb, die Einfl{\"u}sse ausgew{\"a}hlter raum-zeitlicher Faktoren auf die artspezifische Fledermausaktivit{\"a}t {\"u}ber intensiv genutzten Agrarfl{\"a}chen in einer von Agrarwirtschaft dominierten Landschaft zu untersuchen. Dazu habe ich die Fledermausaktivit{\"a}t mittels passiver akustischer Echoortungsaufnahme in den Jahren 2012 bis 2014 auf insgesamt 113 Untersuchungsfl{\"a}chen in offenen Ackerfl{\"a}chen im Nordosten Brandenburgs erfasst. Die Echoortungsrufe in etwa 27.779 Aufnahmen habe ich manuell bis auf die Art bestimmt und die berechneten artspezifischen Aktivit{\"a}tsparameter mit Hilfe von komplexen statistischen Verfahren untersucht. Im ersten Kapitel dieser Arbeit, habe ich die berechneten Aktivit{\"a}tsparameter von {\"o}kologisch unterschiedlichen Fledermausgruppen auf saisonale Muster hin untersucht. Dabei war ich besonders an Unterschieden zu den bekannten saisonalen Aktivit{\"a}tsmustern in naturnahen Habitaten interessiert. Im zweiten Kapitel dieser Arbeit, habe ich den Einfluss von linearen Geh{\"o}lzstrukturen am Feldrand und von kleinen Wasserfl{\"a}chen (S{\"o}llen) innerhalb von Ackerfl{\"a}chen auf die Flug- und Jagdaktivit{\"a}t verschiedener Fledermausarten {\"u}ber diesen Fl{\"a}chen untersucht. Zus{\"a}tzlich war ich daran interessiert, ob sich etwaige Effekte dieser Landschaftselemente auf die Fledermausaktivit{\"a}t im Laufe des Jahres ver{\"a}ndern. Im dritten Kapitel dieser Arbeit war es mein Ziel den Zusammenhang zwischen unterschiedlichen r{\"a}umlichen und zeitlichen Einfl{\"u}ssen auf die artspezifische Fledermausaktivit{\"a}t {\"u}ber offenen Agrarfl{\"a}chen zu untersuchen. Dabei habe ich meine Untersuchungen auf Faktoren fokussiert, die daf{\"u}r bekannt sind Fledermausaktivit{\"a}t zu beeinflussen, wie z.B. Faktoren auf kleinr{\"a}umiger Skala, die mit der Beuteverf{\"u}gbarkeit zusammenh{\"a}ngen, und verschiedene Landschaftscharakteristika auf großr{\"a}umiger Skala. Auf der zeitlichen Skala, habe ich mich auf den Einfluss der Saison konzentriert. Zusammenfassend heben die Ergebnisse dieser Arbeit die Wichtigkeit naturnaher Landschaftselemente f{\"u}r die Fledermausaktivit{\"a}t {\"u}ber Agrarfl{\"a}chen hervor. Allerdings war nicht nur die Landschaftsstruktur f{\"u}r die Fledermausaktivit{\"a}t {\"u}ber Ackerfl{\"a}chen ausschlaggebend, sondern auch der Einfluss von interaktiven Effekten zwischen z.B. Landschaftscharakteristika und der lokalen Beuteverf{\"u}gbarkeit. Ein weiteres Kernergebnis ist die saisonale Variabilit{\"a}t des Einflusses der Landschaftsstruktur auf die Fledermausaktivit{\"a}t. Hierbei hatten bestimmte Landschaftselemente vor allem im Sommer einen großen Einfluss auf die Fledermausaktivit{\"a}t. Das Potenzial der {\"O}kosystemleistung durch spezifische Fledermausarten, welches wiederholt in den unterschiedlichen Kapiteln hervorgehoben wurde, ist ein weiteres Kernergebnis. Da die Fledermausaktivit{\"a}t jedoch stark von der Landschaftsstruktur in der Umgebung abh{\"a}ngt, ist es wichtig diese fledermausfreundlich zu gestalten, um die {\"O}kosystemleistung der Sch{\"a}dlingskontrolle {\"u}ber Agrarfl{\"a}chen nutzen zu k{\"o}nnen. Schlussendlich tr{\"a}gt diese Arbeit in ihrer Gesamtheit zum bestehenden Wissen {\"u}ber die Fledermausbiologie und -{\"o}kologie bei und verdeutlicht die komplexen Wechselwirkungen unterschiedlicher Einfl{\"u}sse auf mehreren raum-zeitlichen Ebenen. Die Ergebnisse dieser Arbeit k{\"o}nnen als Basis zur Verbesserung und Entwicklung von Schutzmaßnahmen f{\"u}r Flederm{\"a}use in intensiv genutzten Agrarlandschaften dienen. Da Flederm{\"a}use als gute Bioindikatoren gelten, k{\"o}nnen effektive Schutzmaßnahmen f{\"u}r Flederm{\"a}use auch zum Schutz anderer Arten beitragen und damit potenziell den weiteren Verlust der Biodiversit{\"a}t in Agrarlandschaften abschw{\"a}chen.},

  abstract  = {Introduction Bats are threatened by agricultural intensification, and although bat ecology in agricultural landscapes is in the focus of current research, the effects of interacting spatiotemporal factors on species-specific bat activity above farmland remain understudied. Our aim was to identify spatiotemporal factors and their interactions relevant for the activity of bat species above conventionally managed arable fields. Methods We repeatedly monitored relative bat activity above open arable fields in Germany using acoustic monitoring. We used site-related biotic and abiotic factors and landscape characteristics across five spatial scales, their combinations, and interactions to identify those factors which best explain variation in bat activity. Results Numerous interactions between landscape characteristics and the insect abundance affected bat activity above fields. For instance, Pipistrellus pipistrellus became more active with increasing insect abundance, but only above fields with a low proportion of woody vegetation cover in the surroundings. Additionally, the level of bat activity in summer depended on landscape characteristics. For example, the activity of Pipistrellus nathusii was relatively low in summer above fields that were surrounded by vegetation patches with a high degree of edge complexity (e.g., hedgerow). However, the activity remained at a relatively high level and did not differ between seasons above fields that were surrounded by vegetation patches with a low degree of edge complexity (e.g., roundly shaped forest patch). Conclusions Our results revealed that landscape characteristics and their interactions with insect abundance affected bat activity above conventionally managed fields and highlighted the opportunistic foraging behavior of bats. To improve the conditions for bats in agricultural landscapes, we recommend re-establishing landscape heterogeneity to protect aquatic habitats and to increase arthropod availability.},

  abstract  = {Long-chain polyunsaturated fatty acids (LC-PUFA) are critical for the health of aquatic and terrestrial organisms; therefore, understanding the production, distribution, and abundance of these compounds is imperative. Although the dynamics of LC-PUFA production and distribution in aquatic environments has been well documented, a systematic and comprehensive comparison to LC-PUFA in terrestrial environments has not been rigorously investigated. Here we use a data synthesis approach to compare and contrast fatty acid profiles of 369 aquatic and terrestrial organisms. Habitat and trophic level were interacting factors that determined the proportion of individual omega-3 (n-3) or omega-6 (n-6) PUFA in aquatic and terrestrial organisms. Higher total n-3 content compared with n-6 PUFA and a strong prevalence of the n-3 PUFA eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) characterized aquatic versus terrestrial organisms. Conversely, terrestrial organisms had higher linoleic acid (LNA) and alpha-linolenic acid (ALA) contents than aquatic organisms; however, the ratio of ALA: LNA was higher in aquatic organisms. The EPA + DHA content was higher in aquatic animals than terrestrial organisms, and increased from algae to invertebrates to vertebrates in the aquatic environment. An analysis of covariance (ANCOVA) revealed that fatty acid composition was highly dependent on the interaction between habitat and trophic level. We conclude that freshwater ecosystems provide an essential service through the production of n-3 LC-PUFA that are required to maintain the health of terrestrial organisms including humans.},
