Characterisation, prevalence and severity of skin lesions caused by ophidiomycosis in a population of wild snakes Open
Ophidiomycosis is an emerging infectious disease affecting wild snakes in the Northern Hemisphere. Recently confirmed in Great Britain, the prevalence, severity and significance of ophidiomycosis has yet to be characterised in free-living …

Warming temperatures drive at least half of the magnitude of long-term trait changes in European birds Open
Significance Climate change is impacting wild populations, but its relative importance compared to other causes of change is still unclear. Many studies assume that changes in traits primarily reflect effects of climate change, but this as…

The environmental predictors of spatio-temporal variation in the breeding phenology of a passerine bird Open
Establishing the cues or constraints that influence avian timing of breeding is the key to accurate prediction of future phenology. This study aims to identify the aspects of the environment that predict the timing of two measures of breed…

Spatial and habitat variation in aphid, butterfly, moth and bird phenologies over the last half century Open
Global warming has advanced the timing of biological events, potentially leading to disruption across trophic levels. The potential importance of phenological change as a driver of population trends has been suggested. To fully understand …

Effects of winter food provisioning on the phenotypes of breeding blue tits Open
Throughout the Western World, huge numbers of people regularly supply food for wild birds. However, evidence of negative impacts of winter feeding on future reproduction has highlighted a need to improve understanding of the underlying mec…

Characteristics determining host suitability for a generalist parasite Open
Host quality is critical for parasites. The common cuckoo Cuculus canorus is a generalist avian brood parasite, but individual females show strong preference for a specific host species. Here, we use three extensive datasets to investigate…
View article: The sensitivity of breeding songbirds to changes in seasonal timing is linked to population change but cannot be directly attributed to the effects of trophic asynchrony on productivity
The sensitivity of breeding songbirds to changes in seasonal timing is linked to population change but cannot be directly attributed to the effects of trophic asynchrony on productivity Open
A consequence of climate change has been an advance in the timing of seasonal events. Differences in the rate of advance between trophic levels may result in predators becoming mismatched with prey availability, reducing fitness and potent…

Spatiotemporal data on pedunculate oak leafing and peak frass dates for the UK Open
Data to accompany paper on “Tritrophic mismatch in space and time”. Observations are on the phenology of oak first leaf date and the peak caterpillar frass date across the UK for the period 1998 to 2016. The oak phenology data were collect…

Passerines may be sufficiently plastic to track temperature‐mediated shifts in optimum lay date Open
Projecting the fates of populations under climate change is one of global change biology's foremost challenges. Here, we seek to identify the contributions that temperature‐mediated local adaptation and plasticity make to spatial variation…
