TLDR
Logistical difficulties preclude a detailed study of dispersal for many species, however incorporating unrealistic dispersal assumptions in spatial population models may yield inaccurate and costly predictions, and further studies are necessary to explore the importance of incorporating specific condition‐dependent dispersal strategies for evolutionary and population dynamic predictions.Abstract:
Knowledge of the ecological and evolutionary causes of dispersal can be crucial in understanding the behaviour of spatially structured populations, and predicting how species respond to environmental change. Despite the focus of much theoretical research, simplistic assumptions regarding the dispersal process are still made. Dispersal is usually regarded as an unconditional process although in many cases fitness gains of dispersal are dependent on environmental factors and individual state. Condition-dependent dispersal strategies will often be superior to unconditional, fixed strategies. In addition, dispersal is often collapsed into a single parameter, despite it being a process composed of three interdependent stages: emigration, inter-patch movement and immigration, each of which may display different condition dependencies. Empirical studies have investigated correlates of these stages, emigration in particular, providing evidence for the prevalence of conditional dispersal strategies. Ill-defined use of the term ‘dispersal’, for movement across many different spatial scales, further hinders making general conclusions and relating movement correlates to consequences at the population level. Logistical difficulties preclude a detailed study of dispersal for many species, however incorporating unrealistic dispersal assumptions in spatial population models may yield inaccurate and costly predictions. Further studies are necessary to explore the importance of incorporating specific condition-dependent dispersal strategies for evolutionary and population dynamic predictions.read more

TL;DR: Recent literature providing strong evidence that individual variation in dispersal has an important impact on both reinforcement and colonization success and therefore must be taken into account when predicting ecological responses to global warming and habitat fragmentation is discussed.

TL;DR: A brave new world with a wider view Researchers have long attempted to follow animals as they move through their environment, but such efforts were limited to short distances and times in species large enough to carry large batteries and transmitters, while new technologies have opened up new frontiers in animal tracking remote data collection.

TL;DR: Recent progress in this emerging field is reviewed and it is suggested that the merging of detailed molecular mechanisms with ecological theory will significantly advance understanding of biofilm biology and ecology.

Mating systems, philopatry and dispersal in birds and mammals
TL;DR: It is argued that the direction of the sex bias is a consequence of the type of mating system, and Philopatry will favour the evolution of cooperative traits between members of the sedentary sex.
