Untersuchung der Lebensraumansprüche des Grauspechts Picus canus und seiner Verbreitungsgrenze in Niedersachsen by Mareike Schneider( )

2 editions published in 2018 in German and held by 19 WorldCat member libraries worldwide

The grey-headed woodpecker (Picus canus) is a semi-frequent species distributed worldwide from West France over Central Europe and East Russia up to Japan and Sumatra. The populated habitats vary and comprise boundary-abundant deciduous wood, alluvial forest, meadow orchard, parkland and coniferous forest in high altitudes. The main diet of the woodpecker is known to be composed of ants. Scarcely more is evidenced about the species autecology. Especially in terms of fundamental habitat patterns grey-headed woodpeckers use in the forest, we have a substantial gap in knowledge. Considering th
Conservation physiology of two closely related, sympatric lemur species, the fat-tailed dwarf lemur (Cheirogaleus medius), and the gray mouse lemur (Microcebus murinus) by Hasina Josué Rakotoniaina( )

The detrimental effects of human-induced habitat loss and degradation on wildlife are pervasive and represent a primary concern for conservation biologists. Understanding how organisms accurately recognise and respond to these challenges is therefore an important goal of conservation-related research. Species are known to respond differently to anthropogenic disturbance and while some are relatively good at coping with a certain degree of perturbation, some face drastic population decline. This heterogeneity in coping abilities has been generally connected to various biological attributes s
Intergroup relationships in Verreaux's sifakas (Propithecus verreauxi) by Flávia Koch de Vasconcellos( )

Wie Tiere ein kollektives Handeln zur Revierverteidigung erreichen und wie sie Beziehungen zwischen benachbarten Gruppen aufbauen ist in letzter Zeit zu einem zentralen Thema in der Verhaltensforschung geworden. Die Stärke einer Gruppe kann von mehreren Faktoren beeinflusst werden, sowohl auf der Gruppen- als auch auf der Individuenebene. In dieser Dissertation untersuchte ich verschiedene Aspekte der Beziehungen zwischen acht Gruppen von Larvensifakas im Westen Madagaskars. Von 2012 bis 2014 wurden detaillierte Verhaltensdaten, ökologische und demographische Daten aufgenommen, um einerseit
Within- and between-group feeding competition in Siberut macaques (Macaca siberu) and Assamese macaques (Macaca assamensis) by Christin Richter( )

2 editions published in 2014 in English and held by 18 WorldCat member libraries worldwide

Feeding competition remains of research interest as it affects growth, survival and reproductive success of individuals. It also limits group size and shapes the social structure of animal groups. Feeding competition is thought to be determined by food resource characteristics, but other factors like predation risk can influence feeding competition as well. The socioecological models have been developed to explain the observed variation in social relationships, by linking resource characteristics to the type and strength of feeding competition, which ultimately influences social relationshi
Feeding competition in wild female Assamese macaques (Macaca assamensis) by Marlies Heesen( )

2 editions published in 2014 in English and held by 17 WorldCat member libraries worldwide

Nahrung ist eine der wichtigsten Ressourcen um die Tiere konkurrieren. Um die Anpassung von lebenden Organismen zu verstehen ist es daher von großem Interesse festzustellen, wie Individuen um solche limitierenden Ressourcen konkurrieren. Bei Säugetieren wird erwartet, dass Weibchen intensiver um Nahrungsressourcen konkurrieren als Männchen, da Weibchen im Allgemeinen geringere Fortpflanzungsraten haben, und ihre Fertilität und Fortpflanzung stärker durch ihren Ernährungszustand beeinflusst werden. Zusätzlich zu dem Einfluss von Nahrungsressourcen auf das Überleben und die Reproduktion von I
Foundations of variation in male aggressiveness and tolerance between chacma baboons (Papio ursinus) in Botswana and Guinea baboons (P. papio) in Senegal by Urs Kalbitzer( )

1 edition published in 2014 in English and held by 17 WorldCat member libraries worldwide

The fitness limiting resource for most male primates is the indivisible fertilization of females. Therefore, males commonly compete aggressively with each other over access to receptive females. Among species, however, there is considerable variation in aggressiveness, and in some species males may even show cooperative behaviors, which is often associated with more relaxed and tolerant social relationships. The proximate and ultimate reasons for this variation may depend on several aspects of a social system, but are not yet entirely understood. Baboons (Papio spp.) constitute a well-suite

Tolerant chimpanzee - quantifying costs and benefits of sociality in wild female bonobos (Pan paniscus) by Niina Orvokki Nurmi( )

2 editions published in 2019 in English and held by 6 WorldCat member libraries worldwide

Social interactions with conspecifics have fitness consequences for individuals. Socio-ecology is a subdiscipline of behavioral ecology. Socio-ecology integrates ecology, sexual selection, inclusive fitness theory, and evolutionary optimality modelling to advance our understanding of how social strategies evolve. Social strategies are sets of repeated individual behavioural decisions from which social systems eventually arise. A successful strategy maximizes an individuals' inclusive fitness. Behavioural decisions are constrained by several factors, many of which stem from the surrounding e
Energetics in wild female Assamese macaques (Macaca assamensis): a behavioral and physiological approach by Sonia Touitou( )

Energy is a key requirement of life. It is involved in life history traits such as body maintenance, growth and reproduction. Energy is a limiting resource and therefore has to be strategically allocated. When facing an energetic challenge (e.g. low food availability), an individual energy balance, i.e. the difference between energy intake and expenditure, is likely to decrease, leading to shifts in energy-allocation strategies. Such challenging situations can bear drastic fitness consequences and two important adaptations have emerged in order to offset these energetic costs. First, indivi

Die Ordnung der Raubtiere (Carnivora) beinhaltet eine Vielzahl von Arten, die sich in ihrer sozialen Organisation und Gehirngröße unterscheiden. Gemäß der Social Intelligence Hypothesis sind Arten, die in größeren Sozialverbänden leben, besonders intelligent und haben im Laufe der Evolution ein größeres Gehirn entwickelt. Bei den Raubtieren scheinen diese Zusammenhänge allerdings nicht zu bestehen. Bisherige Studien konnten keinen Zusammenhang zwischen sozialer Organisation und kognitiven Fähigkeiten finden, da solitäre und gruppenlebende Arten in kognitiven Experimenten gleich abschnitten
The costs and benefits of sociality in semi-free ranging Barbary macaques (Macaca sylvanus) by Nadine Müller( )

2 editions published between 2018 and 2019 in English and held by 4 WorldCat member libraries worldwide

Parasite infections are ubiquitous throughout the animal kingdom, and increased risk of parasite transmission has been suggested as one of the major costs of group living. With bigger group size and higher interaction frequencies, transmission is expected to increase due to higher pathogen exposure. In contrast, social integration and close affiliative relationships are known predictors of increased health, longevity and reproductive success in social animals. Sociality is thus hypothesized to offer fitness benefits by improving health, including reduced susceptibility to infectious disease
Kinship and sociality in wild Assamese macaques (Macaca assamensis): are they related? by Delphine de Moor( )

2 editions published in 2020 in English and held by 4 WorldCat member libraries worldwide

Social bonds are found in social species spanning the entire mammalian kingdom. The formation of such bonds can be adaptive: strong links have been established between social integration and increased survival and/or reproductive success in a diverse range of taxa. A crucial step in understanding how animals benefit from forming social bonds is to understand what drives social partner preferences, and how partner choice can contribute to fitness consequences. One factor that has repeatedly been shown to have a profound influence on the social life of animals is kinship. Social mammals tend
Frugivore behavior and plant spatial genetics by Tiziana A Gelmi-Candusso( )

2 editions published between 2017 and 2019 in English and held by 4 WorldCat member libraries worldwide

Spatial genetics aims to understand the influence of environmental features and biological interactions on gene flow and genetic structure. In plants, spatial genetics is determined by the rate, pattern and spatial extent of gene dispersal within and between populations. Gene dispersal in plants is composed by seed dispersal and pollination. Seed dispersal increases the probabilities of mating between spatially distant, non-related, individuals, reducing the probability of biparental inbreeding, decreasing the incidence of unfavorable traits and increasing genetic diversity. In animal seed
Grunt usage and social monitoring: Investigation of the signaller and the receiver perspectives in a tolerant species of baboons by Lauriane Faraut( )

Understanding society, communication and cognition in non-human primates sheds light on the evolution of our own species. While the acoustic structure in primates is mainly innate, their vocal usage and comprehension/response are more flexible and fluctuate based on social experiences. Because relationships can vary between individuals within the same group and change over time, the contexts of call usage (signaller perspective) and the patterns of response to vocalisations (receiver perspective) is supposed to differ even among closely related species. My thesis project is in line with the
Leaving a solitary life behind: Evolutionary processes leading to sociality in animals by Lluis Socias Martínez( )

2 editions published in 2020 in English and held by 3 WorldCat member libraries worldwide

Die Entwicklung stabiler Tiergruppen ist ein wichtiger Übergang in der Evolution, der aufgrund des selektiven Drucks, der mit sozialen Interaktionen verbunden ist, Veränderungen in der Populationsstruktur und in den aufkommenden Eigenschaften mit sich bringt. Die Sozialität basiert auf Kooperation, ein evolutionäres Puzzle in der darwinistischen Theorie, das auf der Konkurrenz um begrenzte Ressourcen beruht. Im ersten Kapitel stellen wir die Bedeutung der Verwandtschaftsselektion (i.e. Nepotismus) in Frage, um das Auftreten von Tiergruppen zu erklären, das das aktuelle Paradigma darstellt.
Theoretical and empirical analysis of the evolution of cooperation by Peter Bednarik( )

1 edition published in 2014 in English and held by 3 WorldCat member libraries worldwide

Kooperatives Verhalten lässt sich in vielen Bereichen menschlichen Zusammenlebens sowie im gesamten Tierreich beobachten. In evolutionären Modellen wurde gezeigt, dass Netzwerkstrukturen die Kooperation erhöhen können. Empirische Studien versuchten vergeblich diesen Mechanismus auch bei Menschen nachzuweisen. Es scheint, als würden Netzwerke nur dann die Kooperation erhöhen, wenn die Strukturen nicht statisch sind, sondern dynamisch. Das heißt, dass die Individuen die Möglichkeit haben, ihre Partner zu wechseln. Eine wichtige - aber bislang unerforschte - Eigenschaft dynamischer Netzwerke i
Dynamics and fitness benefits of male-male sociality in wild Guinea baboons (Papio papio) by Federica Dal Pesco( )

2 editions published in 2020 in English and held by 3 WorldCat member libraries worldwide

Males living in multi-male groups display a wide range of relationships with co-resident males, varying from high levels of competition, intolerance and avoidance to cooperation, affiliation and social bonds. Despite the wide diversity of male-male relationship dynamics, the existence of multi-male associations and male-male bonds is puzzling, as males compete over un-sharable fertilization. Multi-male associations can emerge as a result of increased between-group competition, which would necessitate communal defense of females. In groups characterized by stable male co-residence, social bo
