Necessity or capacity? Physiological state predicts problem-solving performance in house sparrows | Type | Journal Article | ||

| Abstract | Innovative behaviors such as exploiting novel food sources can grant significant fitness benefits for animals, yet little is known about the mechanisms driving such phenomena, and the role of physiology is virtually unexplored in wild species. Two hypotheses predict opposing effects of physiological state on innovation success. On one hand, poor physiological condition may promote innovations by forcing individuals with poor competitive abilities to invent alternative solutions. On the other hand, superior physiological condition may ensure greater cognitive capacity and thereby better problem-solving and learning performance. To test these hypotheses, we studied the behavior of wild-caught house sparrows (Passer domesticus) in 4 novel tasks of food acquisition, one of which was presented to the birds in repeated trials, and we investigated the relationships of individual performance with relevant physiological traits. We found that problem-solving performance across the 4 tasks was moderately consistent within individuals. Birds with lower integrated levels of corticosterone, the main avian stress hormone, solved the most difficult task faster and were more efficient learners in the repeated task than birds with higher corticosterone levels. Birds with higher concentration of total glutathione, a key antioxidant, solved 2 relatively easy tasks faster, whereas birds with fewer coccidian parasites tended to solve the difficult task more quickly. Our results, thus, indicate that aspects of physiological state influence problem-solving performance in a context-dependent manner, and these effects on problem-solving capacity, probably including cognitive abilities, are more likely to drive individual innovation success than necessity due to poor condition. | ||||

| Abstract | Zusammenfassung Gegenstand und Ziel Seit 2000 siedelt sich der Wolf in Deutschland wieder an. Mit steigenden Wolfszahlen nehmen die durch Wölfe verursachten Nutztierschäden zu, wobei auch Pferde betroffen sind. Ziel der Studie war es, einen Überblick zu dieser Problematik sowie Lösungsansätze zu geben. Material und Methoden Anhand einer Literaturrecherche wurden Daten zur Wolfspopulation in Deutschland, wolfsbedingten Schäden sowie Möglichkeiten und Grenzen des Herdenschutzes beim Pferd eruiert. Eine Online-Befragung von Pferdehaltern/-besitzern diente dazu, die tatsächliche und/oder gefühlte Bedrohung durch Wölfe und die daraus resultierenden Auswirkungen auf die Pferdehaltung zu ermitteln. Ergebnisse Die Literaturrecherche zeigte ein kontinuierliches Anwachsen der Wolfspopulation in den letzten Jahren und insbesondere seit 2016 einen deutlichen Anstieg wolfsverursachter Nutztierschäden, wobei Pferde selten betroffen waren. Bei der Online-Befragung stammte die Hälfte der 574 ausgewerteten Fragebögen aus Brandenburg und Niedersachsen. Den größten Einfluss auf die Gefährdungsbeurteilung eigener Pferde durch die wachsende Wolfspopulation hatte das Wissen der Pferdehalter über Wolfsangriffe im eigenen Landkreis, wobei insbesondere die Aspekte einer Haltung von Jungpferden und Weidegang für die Pferde eine Rolle spielten. 64 % der Befragten gaben an, ihre Pferdehaltung trotz der zunehmenden Wolfspopulation nicht geändert zu haben. Nur 8 von 576 Pferdehaltern gaben amtlich bestätigte Wolfsübergriffe an und 30 hatten einen vermuteten Wolfsschaden amtlichen Stellen nicht gemeldet. Mehr als die Hälfte der Befragten, die Kontakt zu einem Wolfsberater hatten, bezeichneten die Zusammenarbeit als nicht bis wenig zielführend. Schlussfolgerung und klinische Relevanz Die Zahl amtlich bestätigter Wolfsangriffe auf Pferde ist gering. Durch einen grundsätzlich durchgeführten Gentest bei entsprechendem Verdacht ließen sich diese Zahlen objektivieren. Trotz des Bewusstseins einer zunehmenden Gefährdung von Pferden durch Wölfe unternehmen Pferdehalter überwiegend keine prophylaktischen Schutzmaßnahmen. Die Kommunikation zwischen den für das Wolfsmonitoring zuständigen Behörden und den Pferdehaltern erscheint verbesserungswürdig. Abstract Objective Since 2000 the wolf population is reestablishing itself in Germany. In consequence to increasing numbers, livestock damage caused by wolves is on the rise, with horses likewise being affected. The aim of the study was to provide an overview of this challenge and its possible solutions. Material and methods Based on a literature research, data on the wolf population in Germany, wolf-related damage as well as possibilities and limitations of herd protection for horses were evaluated. An online survey addressed to horse owners/keepers served to determine the actual and/or perceived threat posed by wolves and the resulting effects on horse husbandry. Results The literature search showed a continuous increase of the wolf population in recent years as well as a significant increase of wolf-caused livestock damage in general especially since 2016; although horses were rarely affected. Half of the 574 evaluated questionnaires were from Brandenburg and Lower Saxony. The greatest influence on the individual risk assessment concerning their own horses by the growing wolf population was the horse owners� knowledge of wolf attacks in their own county. Especially the aspects of keeping young horses as well as pasture keeping played a significant role. 64 % of respondents indicated that they had not changed their horse management practices despite the increasing wolf population. Only 8 of 576 horse owners had reported officially confirmed wolf attacks and 30 respondents had not reported a suspected wolf damage to official agencies. More than half of the respondents who had contact with a wolf advisor described the cooperation as either not or only slightly purposeful. Conclusion and clinical relevance The number of officially confirmed wolf attacks on horses is low. These numbers could be objectified by a routinely performed genetic test in case of corresponding suspicion. Despite the awareness of an increasing danger of horses by wolves, horse owners mostly do not undertake prophylactic protection measures. The communication between responsible authorities for wolf monitoring and horse owners seems to be in need of improvement. |

Military training areas facilitate the recolonization of wolves in Germany | Type | Journal Article | ||

| Abstract | Abstract Wolves (Canis lupus) are currently showing a remarkable comeback in the highly fragmented cultural landscapes of Germany. We here show that wolf numbers increased exponentially between 2000 and 2015 with an annual increase of about 36%. We demonstrate that the first territories in each newly colonized region were established over long distances from the nearest known reproducing pack on active military training areas (MTAs). We show that MTAs, rather than protected areas, served as stepping-stones for the recolonization of Germany facilitating subsequent spreading of wolf territories in the surrounding landscape. We did not find any significant difference between MTAs and protected areas with regard to habitat. One possible reason for the importance of MTAs may be their lower anthropogenic mortality rates compared to protected and other areas. To our knowledge, this is the first documented case where MTAs facilitate the recolonization of an endangered species across large areas. | ||||
