Sexual differences in the foraging behaviour of parents have been observed a number sexually sizedimorphic birds, particularly seabirds, and usual inference has that these sex–specific are mediated primarily by body size. To test this explanation, we compared monomorphic seabird species, northern gannet Morus bassanus. Using specially designed instruments radio telemetry found individuals both sexes were consistent directions durations their trips. However, there significant males females....
Summary Remote‐sensing measurements of marine primary productivity are widely used to predict the distribution and movements top predators, despite fact that predators do not feed directly on phytoplankton but several trophic levels higher up food chain. To test for potential links between top‐predator feeding hotspots, we assessed spatial match–mismatch across four Benguela upwelling zone (south‐east Atlantic). The chain studied consisted phytoplankton, zooplankton (copepods), pelagic fish...

Sex differences in the foraging behaviour of adults have been observed a number sexually size‐dimorphic birds, and usual inference has that these sex‐specific are driven primarily by body size. An alternative explanation is result from sex unrelated to size, such as nutritional requirements. To examine hypotheses, parents was compared between two sympatric congeneric species seabird, Brown Booby Sula leucogaster , which highly (females 38% larger) Red‐footed S. sula size less marked 15%...

Age-related variation in demographic rates is now widely documented wild vertebrate systems, and has significant consequences for population evolutionary dynamics. However, the mechanisms underpinning such variation, particularly later life, are less well understood. Foraging efficiency a key determinant of fitness, with implications individual life history trade-offs. A variety faculties known to decline old age, as muscular function visual acuity, likely influence foraging performance. We...

Summary In many animal populations a small proportion of individuals produce the majority surviving offspring, but underlying mechanisms are unclear. Behaviour may be an important determinant variation in fitness: ‘high‐quality’ have enhanced abilities foraging or predator and parasite avoidance. The role behaviour determining quality was examined using common guillemot Uria aalge , monogamous seabird with biparental care. Using novel mixed model approach, we analysed binary data on breeding...
Carry‐over effects have major implications for individual fitness and population evolutionary dynamics. The strength of these is dependent on an individual's intrinsic performance the environmental conditions it experiences. However, understanding relative importance underpinning seasonal interactions has proved extremely challenging, since they covary. A powerful approach longitudinal measurement individuals across a range conditions, whereby each animal effectively acting as its own...
There is growing interest in the effects of wind on wild animals, given evidence that speeds are increasing and becoming more variable some regions, particularly at temperate latitudes. Wind may alter movement patterns or foraging ability, with consequences for energy budgets and, ultimately, demographic rates. These expected to vary among individuals due intrinsic factors such as sex, age feeding proficiency. Furthermore, this variation predicted become marked conditions deteriorate, which...
Given the potential role of telomeres as biomarkers individual health and ageing, there is an increasing interest in studying telomere dynamics a wider range taxa fields ecology evolutionary biology. Measuring length across lifespan wild animal systems essential for testing these hypotheses, may be aided by archived blood samples collected part longitudinal field studies. However, sample collection, storage, DNA extraction methods influence measurement, it may, therefore, difficult to...

Multipoint regression variance components methods used to analyze 372 polymorphic markers. Statistically compelling evidence (P values .0057 .00023, respectively) was found on chromosome 1. Our results support idea that...
Plunge‐diving is a specialised hunting tactic used by some avian predators to overcome the high buoyancy encountered near water surface and surprise prey. However, plunge‐diving effective only certain depth; access deeper prey, birds need use an additional method of propulsion, e.g. wings or feet.

Altruism and selfishness are fundamental characteristics of human animal societies. Among colonial biparental species, breeding outcome depends on interactions between mates neighbours. However, the relationships cooperation within among partnerships fitness have not been fully investigated. We show that in highly common guillemot ( Uria aalge ), altruistic behaviour (allopreening) towards a mate was positively related to long-term fitness, whereas allopreening neighbour current fitness....
Age-related variation in reproductive performance is ubiquitous wild vertebrate populations and has important consequences for population evolutionary dynamics. The ageing trajectory shaped by both within-individual processes, such as improvement senescence, the among-individual effects of selective appearance disappearance. To date, few studies have compared role these different drivers among species or populations. In this study, we use nearly 40 years longitudinal monitoring data to...

However, there an increasing recognition differential impact such factors individuals since marked variation in individual performance.
