“…However, few examples of such responses are available (Bradshaw & Holzapfel, 2001;Etterson & Shaw, 2001;Merilä et al, 2001;Ré ale et al, 2003). Secondary sexual characters have a high potential for evolutionary change (Pomiankowski & Møller, 1995), because such characters are commonly subject to intense directional selection, but also have high evolvabilities estimated in terms of the additive genetic coefficient of variation (Darwin, 1871;Andersson, 1994;Pomiankowski & Møller, 1995).…”

The ability of organisms to respond evolutionarily to rapid climatic change is poorly known. Secondary sexual characters show the potential for rapid evolutionary change, as evidenced by strong divergence among species and high evolvability. Here we show that the length of the outermost tail feathers of males of the socially monogamous barn swallow Hirundo rustica, feathers that provide a mating advantage to males, has increased by more than 1 standard deviation during the period from 1984 to 2003. Barn swallows from the Danish population studied here migrate through the Iberian Peninsula to South Africa in fall, and return along the same route in spring. Environmental conditions on the spring staging grounds in Algeria, as indexed by the Normalized Difference Vegetation Index, predicted tail length and change in tail length across generations. However, conditions in the winter quarters and at the breeding grounds did not predict change in tail length. Environmental conditions in Algeria in spring showed a temporal deterioration during the study period, associated with a reduction in annual survival rate of male barn swallows. Phenotypic plasticity in tail length of males, estimated as the increase in tail length from the age of 1 to 2 years, decreased during the course of the study. Estimates of directional selection differentials for male tail length with respect to mating success, breeding date, fecundity, survival and total selection showed temporal variation, with the intensity of breeding date selection, survival selection and total selection declining during the study. Response to selection as estimated from the product of heritability and total selection was very similar to the observed temporal change in tail length. These findings provide evidence of rapid micro‐evolutionary change in a secondary sexual character during a very short time period, which is associated with a rapid change in environmental conditions.

“…Similarly, birds in good condition generally lay eggs earlier in a given season than those in poor condition (Price et al 1988;Rowe et al 1994). In red squirrels (Tamiasciurus hudsonicus), variation in breeding date is also influenced by maternal condition, itself a response to food availability in the previous year (Réale et al 2003). Thus, both iteroparity and environmental variation in resource availability obscure the time -size trade-off because the resources available for reproduction are not solely determined by the individual's ability to acquire resources in a particular growing season.…”

Phenology affects nearly all aspects of ecology and evolution. Virtually all biological phenomenafrom individual physiology to interspecific relationships to global nutrient fluxes-have annual cycles and are influenced by the timing of abiotic events. Recent years have seen a surge of interest in this topic, as an increasing number of studies document phenological responses to climate change. Much recent research has addressed the genetic controls on phenology, modelling techniques and ecosystem-level and evolutionary consequences of phenological change. To date, however, these efforts have tended to proceed independently. Here, we bring together some of these disparate lines of inquiry to clarify vocabulary, facilitate comparisons among habitat types and promote the integration of ideas and methodologies across different disciplines and scales. We discuss the relationship between phenology and life history, the distinction between organismal-and population-level perspectives on phenology and the influence of phenology on evolutionary processes, communities and ecosystems. Future work should focus on linking ecological and physiological aspects of phenology, understanding the demographic effects of phenological change and explicitly accounting for seasonality and phenology in forecasts of ecological and evolutionary responses to climate change.

“…Adaptive tracking has been quantified in several long-term studies, including the Galapagos finches (Geospiza spp.) [43,44], great tits (Parus major) [45,46] and red squirrels (Tamisciurus hudsonius) [47,48]. These population have all tracked some form of environmental change, such as gradual and sustained climate change [46,47] or abrupt, if not sustained, stochastic weather events [49].…”

The current rapid rate of human-driven environmental change presents wild populations with novel conditions and stresses. Theory and experimental evidence for evolutionary rescue present a promising case for species facing environmental change persisting via adaptation. Here, we assess the potential for evolutionary rescue in wild vertebrates. Available information on evolutionary rescue was rare and restricted to abundant and highly fecund species that faced severe intentional anthropogenic selective pressures. However, examples from adaptive tracking in common species and genetic rescues in species of conservation concern provide convincing evidence in favour of the mechanisms of evolutionary rescue. We conclude that low population size, long generation times and limited genetic variability will result in evolutionary rescue occurring rarely for endangered species without intervention. Owing to the risks presented by current environmental change and the possibility of evolutionary rescue in nature, we suggest means to study evolutionary rescue by mapping genotype → phenotype → demography → fitness relationships, and priorities for applying evolutionary rescue to wild populations.
