Individual risk and reward in the wild. A study on blue tits
Behavioural biologists seek to understand why individuals of the same species differ in their behaviour. The "pace-of-life syndrome" (POLS) hypothesis offers a framework to explain such individual behavioural variation. It puts forth that individuals differ broadly in how they take risks in their …

Cheetah (Acinonyx jubatus) mortality and survival in fenced reserves as part of a managed metapopulation across South Africa
… require expansive habitat to meet their life history needs making them vulnerable to the loss and fragmentation of natural habitat. This, in addition to human persecution has led to substantial population and range reductions of most of the world’s large carnivores over the past century. …

An experimental demographic approach to exotic plant success: <b>Cynoglossum officinale</b> in its native and introduced ranges
… How these changed conditions influence individual life-history traits, and what particular factors spur increases in population abundance in the introduced versus native range, are not well understood. I conducted parallel experiments in both the native and introduced ranges of a …

Genotypic Differences and Life-History Trade-Offs in the Freshwater Zooplankton, Daphnia Pulicaria, Under Natural Levels of Food Limitation
… of growth, reproduction and survivorship of an individual are the key components of life history, which reflect fitness performance of a genotype. Examining the variation in life history performance among genotypes provides an avenue for which genotypic fitness differences can be compared. The …

Understanding Patterns of Phenotypic Variation in a Contemporary Population and Ancient Lineage of Fishes
Within species, individuals in wild populations are often phenotypically diverse, exhibiting differences in many complex traits. While genetic variation undoubtedly explains some portion of phenotypic diversity in the wild, its effects can be obscured by environmental factors, which often also play …

Sociality in African mole-rats : exploring how rainfall affects dispersal and genetic exchange in the Natal mole-rat (Cryptomys hottentotus natalensis)
… reproductive suppression, but their ecology and life history has not been reported in detail. This study used capture-mark recapture methods to investigate life history, population demographics, behaviour, and gene flow in wild Natal mole-rats living at a high elevation site in the southern …
