Data from: Resource stability and geographic isolation are associated with genome divergence in western Palearctic crossbills

Thomas L. Parchman, Pim Edelaar, Kathryn Uckele, Eduardo T. Mezquida, Daniel Alonso, Joshua P. Jahner, Ron W. Summers & Craig W. Benkman
While many conifers produce annually variable seed crops, serotinous species (which hold seeds in cones for multiple years) represent unusually stable food resources for seed predators. Such stability is conducive to residency and potentially population divergence of consumers as exemplified by the Cassia crossbill (Loxia sinesciuris) in North America. We used genotyping-by-sequencing to test whether three Mediterranean subspecies of common crossbills (L. curvirostra) associated with the serotinous Aleppo pine (Pinus halepensis) were more genetically distinct...

Data from: Combined bottom-up and top-down pressures drive catastrophic population declines of Arctic skuas in Scotland

Allan Perkins, Norman Ratcliffe, Dave Suddaby, Brian Ribbands, Claire Smith, Pete Ellis, Eric Meek & Mark Bolton
1. Understanding drivers of population change is critical for effective species conservation. In the northeast Atlantic Ocean, recent changes amongst seabird communities are linked to human and climate change impacts on foodwebs. Many species have declined severely, with food shortages and increased predation reducing productivity. Arctic skua Stercorarius parasiticus, a kleptoparasite of other seabirds, is one such species. 2. The aim of the study was to determine relative effects of bottom-up and top-down pressures on...

Data from: Sex-specific patterns of reproductive senescence in a long-lived reintroduced raptor

Megan Murgatroyd, Staffan Roos, Richard Evans, Alex Sansom, D. Philip Whitfield, David Sexton, Robin Reid, Justin Grant & Arjun Amar
1) For many species there is evidence that breeding performance changes as an individual ages. In iteroparous species, breeding performance often increases through early-life and is expected to level out or even decline (senesce) later in life. Furthermore, an individual’s sex and conditions experienced in early-life can affect breeding performance and how this changes with age. 2) Long-term monitoring of individuals from reintroduced populations can provide unique opportunities to explore age-related trends in breeding performance...

Data from: Large birds travel farther in homogeneous environments

Aim: Animal movement is an important determinant of individual survival, population dynamics, and ecosystem structure and function. Yet it is still unclear how local movements are related to resource availability and the spatial arrangement of resources. Using resident bird species and migratory bird species outside of the migratory period, we examined how the distribution of resources affect the movement patterns of both large terrestrial birds (e.g., raptors, bustards, hornbills) and waterbirds (e.g., cranes, storks, ducks,...

Data from: Have Welsh agri-environment schemes delivered for focal species? Results from a comprehensive monitoring programme

1. Agri-environment schemes (AES) have been criticised for being inadequately monitored and for not delivering the expected benefits to nature. Consequently, the Welsh Government funded a comprehensive programme of monitoring of Welsh AES, which took place between 2009 and 2012. The AES assessment focused primarily on Tir Gofal (which translates as “Land in Care”), but also included the Organic Farming Scheme, and monitoring focused on a range of taxa of conservation importance: arable plants, grassland...

Data from: Seven decades of mountain hare counts show severe declines where high‐yield recreational game bird hunting is practised

Adam Watson & Jeremy D. Wilson
Recreational hunting is widespread and can benefit nature conservation when well‐practised, monitored, and regulated. Management for recreational red grouse Lagopus lagopus scotica shooting on upland heathland in the UK causes conservation conflict because the intensive habitat, predator, and disease management needed to maintain high‐grouse densities for “driven” shooting has detrimental environmental impacts, notably for raptor populations. Sustainable management of mountain hares Lepus timidus scoticus, a game species in the same landscapes, poses a challenge. Control...

Data from: Nesting success and nest-site selection of white-rumped vultures (Gyps bengalensis) in western Maharashtra, India

Iravatee D Majgaonkar, Christopher G. R. Bowden, Suhel Quader & Iravatee Majgaonkar
A few breeding populations of White-rumped Vultures Gyps bengalensis still survive in pockets of their original vast range in India, having weathered a diclofenac induced population decline of 99.9% since the early 1990s. These breeding populations are potential sources of recruits, now that the overall population appears to be stabilising or even recovering in some areas. We studied two White-rumped Vulture nesting colonies in the Raigad district of coastal Maharashtra in 2013-14, to investigate site-specific...

Data from: Metapopulation dynamics of Roseate Terns: sources, sinks and implications for conservation management decisions

Adam Seward, Norman Ratcliffe, Steve Newton, Richard Caldow, Daniel Piec, Paul Morrison, Tom Cadwallender, Wesley Davies & Mark Bolton
1. Habitat management to restore or create breeding sites may allow metapopulations to increase in size and reduce the risk of demographic stochasticity or disasters causing metapopulation extinction. However, if newly restored or created sites are of low quality, they may act as sinks that draw individuals away from better quality sites to the detriment of metapopulation size. 2. Following intensive conservation effort, the metapopulation of roseate tern (Sterna dougallii) in NW Europe is recovering...
