“…Previous studies have also shown betweenyear variation in estimated moult duration (Bensch and Grahn 1993;Smith and Sheeley 1993), while other studies have reported that moult speed did not vary across years (Borras et al 2004). On the other hand, inter-annual variation in breeding success has also been reported in wild birds (Pajuelo et al 1992;Cézilly et al 1995;Forbes 2010). Such differences could be explained by annual variations in environmental factors such as climate or food availability that can affect moult phenology and/or key reproductive traits of birds (Bryant 1975;Murphy 1986;Smith and Sheeley 1993;Renfrew et al 2011).…”

Carry-over effects take place when events occurring in one season influence individual performance in a subsequent season. Blood parasites (e.g. Plasmodium and Haemoproteus) have strong negative effects on the body condition of their hosts and could slow the rate of feather growth on the wintering grounds. In turn, these winter moult costs could reduce reproductive success in the following breeding season. In house martins Delichon urbica captured and studied at a breeding site in Europe, we used ptilochronology to measure growth rate of tail feathers moulted on the winter range in Africa, and assessed infection status of blood parasites transmitted on the wintering grounds. We found a negative association between haemosporidian parasite infection status and inferred growth rate of tail feathers. A low feather growth rate and blood parasite infections were related to a delay in laying date in their European breeding quarters. In addition, clutch size and the number of fledglings were negatively related to a delayed laying date and blood parasite infection. These results stress the importance of blood parasites and feather growth rate as potentially mechanisms driving carry-over effects to explain fitness differences in wild populations of migratory birds.

“…The population and community structure of lotic vegetation (Haslam, 1978;Brock, 1986), fishes (Puckridge et al, 1998) and non-marine waterbirds (Cézilly et al, 1995) are all influenced by the variability of annual runoff.…”

Abstract:The impact of changing catchment vegetation type on mean annual runoff has been known for some time, however, the impact on the variability of annual runoff has been established only recently. Differences in annual actual evapotranspiration between vegetation types and the potential effect of changing vegetation type on mean annual runoff and the variability of annual runoff are briefly reviewed. The magnitude of any change in the variability of annual runoff owing to a change in catchment vegetation type is related to the pre-and post-change vegetation types and the seasonality of precipitation, assuming that the variability of annual precipitation remains constant throughout. Significant implications of the relationship between vegetation type and the variability of annual runoff are presented and discussed for water resource management, stream ecology and fluvial geomorphology.

“…We developed an index of chick body condition using the residuals from the linear relationship between chick weight and tarsus length (Cezilly et al 1995). An individual chick's deviation from this general relationship indi cates whether it is above or below average body weight for its size; i.e.…”

Mechanisms of population divergence in seabirds are poorly understood. We evaluated whether divergent patterns of chick development among wedge-tailed shearwater Puffinus pacificus populations are facultative responses to short-term fluctuations in food availability, or fixed colony-specific phenomena potentially associated with differences in local resource availability. Supplementary feeding at Heron Island increased food intake to levels equal to, or greater than, those observed at Lord Howe Island. In supplemented chicks, mass accumulation per gram of food received was inversely related to current body stores, up to a maximum storage level set by body size. Significantly, maximum storage was lower for Heron Island than for Lord Howe Island chicks at equivalent body size. In contrast, relative allocation to skeletal growth did not differ between supplemented and control chicks, was not influenced by body condition and did not increase to levels observed at Lord Howe Island. Overall, the present study showed that supplemented chicks were unable to use short-term increases in food availability to increase relative mass stores or rates of skeletal development, implying that both life-history parameters have some colony-specific components that are divergent between the locations of this study. Our findings add weight to previous studies suggesting that phenotypic plasticity and/or genetic drift due to philopatry cannot fully explain patterns of morphological, behavioural and physiological divergence among these 2 shearwater colonies.KEY WORDS: Colony-specific development · Chick growth · Local adaptation · Puffinus pacificus · Supplementary feedingResale or republication not permitted without written consent of the publisher
