Article
Full-text available
The social mole-rats of the family Bathyergidae show elaborate social organisation that may include division of labour between breeders and non-breeders as well as across non-breeders within their groups. However, comparative behavioural data across the taxa are rare and contrasts and similarities between species are poorly understood. Field studie...

Full-text available
Dispersal from the natal site to breeding sites is a crucial phase in the life history of animals and can have profound effects on the reproductive ecology and the structure of animal societies. However, few studies have assessed dispersal dynamics in subterranean mammals and it is unknown whether dispersal distances are constrained by living under...

Background: In mammals, the gut microbiome has important effects on the health of their hosts. Recent research highlights that animal populations that live in captivity often differ in microbiome diversity and composition compared to wild populations. However, the changes that may occur when animals move to captivity remain difficult to predict and...
Article
1. Supervised learning of behavioral modes from body‐acceleration data has become a widely used research tool in Behavioral Ecology over the past decade. One of the primary usages of this tool is to estimate behavioral time budgets from the distribution of behaviors as predicted by the model. These serve as the key parameters to test predictions ab...

Full-text available
Background The transport and storage of samples in temperatures of minus 80 °C is commonly considered as the gold standard for microbiome studies. However, studies conducting sample collection at remote sites without a reliable cold-chain would benefit from a sample preservation method that allows transport and storage at ambient temperature. Meth...

Damaraland mole-rats ( Fukomys damarensis) are usually viewed as a eusocial or obligate cooperative breeder in which successful reproduction is dependent on help from closely related group members. However, because longitudinal studies of mole-rats in their natural environment are uncommon, the extent to which successful reproduction by breeders re...

Full-text available
Living with relatives can be highly beneficial, enhancing reproduction and survival. High relatedness can, however, increase susceptibility to pathogens. Here, we examine whether the benefits of living with relatives offset the harm caused by pathogens, and if this depends on whether species typically live with kin. Using comparative meta-analysis...

Living with relatives can be highly beneficial, enhancing reproduction and survival. However, high relatedness can increase susceptibility to pathogens, a phenomenon known as the 'monoculture effect'. Here we examine if the benefits of living with relatives offsets the harm caused by pathogens, and if this depends if species typically live with kin...

Full-text available
Background: Imbalances in the gut microbial community (dysbiosis) of vertebrates have been associated with several gastrointestinal and autoimmune diseases. However, it is unclear which taxa are associated with gut dysbiosis, and if particular gut regions or specific time periods during ontogeny are more susceptible. We also know very little of th...
Preprint
Dysbiosis in the vertebrate gut microbiome has been associated with several diseases. However, it is unclear whether particular gut regions or specific time periods during ontogeny are responsible for the development of dysbiosis, especially in non-model organisms. Here we examine the microbiome associated with dysbiosis in different parts of the g...
Article
The development of gut microbiota during ontogeny in vertebrates is emerging as an important process influencing physiology, immunity, and fitness. However, there is little knowledge of how bacteria colonise the juvenile gut, how this is influenced by changes in the diversity of gut bacteria, and to what extent this influences host fitness, particu...
Article
Full-text available
The coexistence of ecologically similar species might be counteracted by ecological drift and demographic stochasticity, both of which erode local diversity. With niche differentiation, species can be maintained through performance trade-offs between environments, but trade-offs are difficult to invoke for species with similar ecological niches. Su...

The development of gut microbiota during ontogeny in vertebrates is emerging as an important process influencing physiology, immune system, health, and adult fitness. However, we have little knowledge of how the gut microbiome is colonised and develops in non-model organisms, and to what extent microbial diversity and specific taxa influence change...
Article
Full-text available
Sexual conflict is a pervasive evolutionary force that can reduce female fitness. Experimental evolution studies in the laboratory might overestimate the importance of sexual conflict since the ecological conditions in such settings typically include only a single species. Here, we experimentally manipulated conspecific male density (high or low) a...

During my PhD will I explore the causes and consequences of cooperative behaviour and growth in social mole-rats. I will work with captive and wild populations and investigate the gut-microbiome of these animals as a starting point.
