Intergroup relationships in Verreaux's sifakas (Propithecus verreauxi) by Flávia Koch de Vasconcellos( )

2 editions published in 2015 in English and held by 18 WorldCat member libraries worldwide

How animals achieve collective action for territorial defense and how they establish relationships between neighboring groups has recently become a central topic in the study of animal behavior. The power of a group can be influenced by multiple factors at the group and at the individual level. In this dissertation I investigated aspects of intergroup relationships between eight groups of Verreaux's sifakas in western Madagascar. Detailed behavioral, ecological and demographic data were recorded between 2012 and 2014 to investigate the factors influencing the individual participation, and t
The role of acoustic and visual signals in species recognition in true lemurs (Eulemur: Primates) by Miadana Hanitriniaina Markolf Rakotonirina( )

Signals represent important tools for animal social behavior. Numerous animal species use signals for communication as they serve as information transmitted from one individual to another. Signals also play essential roles in the evolution and the diversification of species as they can function for species recognition in several taxa. Additionally, they have evolved under several selective pressures such as natural selection through adaptation to natural habitats, sexual selection for species recognition or simply by random genetic drift. Several animal species including non-human primates
Determinants and outcomes of group coordination and decision-making in red-fronted lemurs (Eulemur rufifrons) by Lennart Pyritz( )

1 edition published in 2011 in English and held by 13 WorldCat member libraries worldwide

In order to reap the benefits of group-living, gregarious animals have to maintain group cohesion. However, differences among group members in terms of sex, age or physiological constitution lead to different activity budgets and motivations, which, in turn, act as a centrifugal force on group cohesion. In order to stay cohesive despite inter-individual conflicts, groups must coordinate collective actions by making shared or unshared consensus decisions. In this context, single group members often adopt different behavioural roles, i.e. certain individuals emerge as leaders, others as followers. In the last decade, a number of studies explored single aspects of coordinated behaviour in the context of group movements, covering a wide range of taxa. Yet, comparisons among studies are still hampered by ambiguous terminology and inconsistent concepts. In addition, taxon- and condition-specific determinants of coordination processes and decision-making under natural conditions remain poorly understood. I addressed both of these general issues in my thesis. First, I outlined why group movements emerged as the major paradigm of coordination research and why primates provide an excellent model taxon in this context, followed by a review of several aspects related to primate group movements

Animal behaviour : evolution and mechanisms by Nils Anthes( )

2 editions published in 2010 in English and held by 6 WorldCat member libraries worldwide

The study of animal behaviour is one of the fastest growing sub-disciplines in biology. The resulting diversity of conceptual approaches and methodological innovations makes it increasingly difficult for professionals and students to keep abreast of important new developments. This edited volume provides up-to-date reviews that facilitate orientation in key areas of animal behaviour, including communication, cognition, conflict, cooperation, sexual selection and behavioural variation. The contributions address evolutionary and proximate aspects of behaviour and also cover both invertebrates and vertebrates. Important concepts are dealt with in separate glossaries and key examples highlighted in separate text boxes. Richly illustrated with colour figures, this volume offers a well structured overview of all the main developments in current animal behaviour research. It is ideal for teaching upper-level courses, where it will be essential reading for advanced students familiar with basic concepts and ideas
Group Coordination Processes and Determinants of Leadership in Red-fronted Lemurs (Eulemur rufifrons) by Anna Lucia Sperber( )

3 editions published in 2019 in English and held by 4 WorldCat member libraries worldwide

For animals to enjoy the benefits of group living it is vital that they coordinate their activities despite divergent needs. The challenge this poses becomes apparent when animals are moving between resources. In this thesis I investigated several aspects that determine a group's movement coordination: the coordination of departure time, the characteristics of initiators and the joining process. The subjects of my studies were four groups of wild red-fronted lemurs (Eulemur rufifrons). in Kirindy Forest, Western Madagascar. I combined observations of naturally occurring group movements with
Determinants of cognitive performance and social preferences across age in Barbary macaques (Macaca sylvanus) by Eva-Maria Rathke( )

2 editions published in 2021 in English and held by 4 WorldCat member libraries worldwide

Aging is a universal process that occurs in almost all organisms and is defined as a progressive decrease in physiological functioning. For centuries, researchers have been interested in aging processes and their consequences. This is partly due to the fact that the proportion of older adults in human societies worldwide has increased in recent decades. In addition to research on the physiological basis of aging, it becomes increasingly important to study social aging. With increasing age, the size of the social network often decreases, which can have an impact on health and mortality risk

Social relationships: key to gut microbiome composition in wild redfronted lemurs? by Sonia Tatiana Murillo Corrales( )

2 editions published in 2022 in English and held by 4 WorldCat member libraries worldwide

The gut microbiome consists of the prokaryotic and eukaryotic communities inhabiting the gastrointestinal tract of an animal and plays a pivotal role in the health of the host. This microbial community is highly dynamic and the factors driving these fluctuations remain to be determined. This thesis presents a longitudinal study investigating the factors that shape the gut microbiome of wild redfronted lemurs aiming to detect an impact from social relationships. Social relationships can influence the gut microbiome directly through transmission of microorganisms during social interactions, o

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
Cognitive adaptations in two sympatric mouse lemur species occupying different ecological niches by Johanna Henke-von der Malsburg( )

Mit kognitiven Fähigkeiten können Tiere Informationen aus der abiotischen und biotischen Umwelt wahrnehmen, verarbeiten und auf diese Informationen in einem angemessenen Umfang reagieren. Die Untersuchung kognitiver Variabilität zwischen Individuen und Arten ist von großem wissenschaftlichem Interesse, das zur Formulierung mehrerer Hypothesen zur Erklärung kognitiver Evolution geführt hat. Hirnareale können in Größe und Entwicklung mit kognitiven Fähigkeiten, die sie verarbeiten korrelieren, und sozio-ökologische Faktoren wurden mit verschiedenen Maßen zur kognitiven Entwicklung in Verbindu
Measuring communicative complexity across modalities: a new framework in the context of the “social complexity hypothesis” and its application in true lemurs by Louise Peckre( )

Die Studie der kommunikativen Komplexität über verschiedene Modalitäten: Ein neuer Ansatz im Kontext der "Sozialen Komplexitätshypothese“ und seine Anwendung in der Gattung Eulemur. Tiere verfügen über eine erstaunliche Vielfalt an Kommunikationssystemen, die sich in ihrer Beschaffenheit und in der Anzahl an produzierten Signalen wesentlich unterscheiden. Diese Varianz in der kommunikativen Komplexität wurde konzeptionell und empirisch der sozialen Komplexität zugeschrieben und als “social-complexity hypothesis for communicative complexity” (SCHCC) zusammengefasst. So sind gruppenlebende Ti
Cognition in the wild Individual differences in cognitive abilities and their link with fitness in a wild primate, the grey mouse lemur (Microcebus murinus) by Franziska Hübner( )

Cognition, the process by which animals acquire, process, store and use information from their environment, plays a major role in various behaviours across all aspects of an individuals' life. However, despite this overall importance of cognitive abilities, we still know little about how cognitive traits evolved. In the past, research on cognitive evolution focussed on comparing different species in their cognitive abilities and linked variation in cognition to inter-specific differences in ecological and social conditions. This comparative approach helps to understand when in evolutionary
