Eco-evolutionary dynamics
TLDR
This special feature about ‘eco-evolutionary dynamics’ brings together biologists from empirical and theoretical backgrounds to bridge the gap between ecology and evolution and provide a series of contributions aimed at quantifying the interactions between these fundamental processes.

Early onset of vegetation growth vs. rapid green-up: impacts on juvenile mountain ungulates.
TLDR
The results suggest that attempts to forecast how warmer winters and springs will affect animal population dynamics and life histories in alpine environments should consider factors influencing the rate of changes in primary production during green-up and the timing of vegetation onset.

Matrix models for a changeable world: the importance of transient dynamics in population management
TLDR
Recent theoretical advances in deterministic transient analysis of matrix projection models are reviewed, considering how disturbance can alter population dynamics by provoking a new population trajectory.

The Evolutionary Demography of Ecological Change: Linking Trait Variation and Population Growth
TLDR
It is reported that the distribution of body sizes within a population of Soay sheep can markedly influence population dynamics, accounting for up to one-fifth of observed population growth.

Eco-evolutionary dynamics: disentangling phenotypic, environmental and population fluctuations
TLDR
Applying a recently published conceptual framework, the relative importance of phenotypic and environmental variability on annual population growth in five ungulate populations is compared and it is suggested that neither is worthy of neglect.

Individual quality: tautology or biological reality?
TLDR
Four key distinctions are highlighted between the views and uses of quality: using different types of quality traits from a variety of conceptual frameworks may prevent researchers from adopting a single definition of quality.

Stochastic predation events and population persistence in bighorn sheep
TLDR
The dynamics of three populations of individually marked bighorn sheep monitored for 24–28 years are considered and it is suggested that such processes may be common.

Intense selective hunting leads to artificial evolution in horn size
TLDR
The authors' analyses revealed a significant decline in genetic value for horn length of rams, consistent with an evolutionary response to artificial selection on this trait, and provides support for the contention that selective hunting led to a reduction in horn length through evolutionary change.

Male mating effort in a polygynous ungulate
TLDR
Mating effort during the rut was unrelated to ram overwinter survival, but longevity was positively correlated with mating effort between 2 and 5 years of age, suggesting that in natural populations a few high quality males enjoy both high mating success and high survival.

Foraging time of rutting bighorn rams varies with individual behavior, not mating tactic
TLDR
Compared to expectation, individual rams observed both coursing and tending spent less time foraging when coursing than when tending, indicating that males either modify their behavior according to available metabolic reserves or adjust the energy devoted to rutting activities to the level of expected benefits.
