Abstract Intensification of agriculture since the 1950s has enhanced availability, competitive ability, crude protein content, digestibility and extended growing seasons forage grasses. Spilled cereal grain also provides a rich food source in autumn winter. Long‐distance migratory herbivorous geese have rapidly exploited these feeding opportunities most species shown expansions range population size last 50 years. Results long‐term studies are presented from two Arctic‐breeding populations,...
The Kangerlussuaq area of southwest Greenland encompasses diverse ecological, geomorphic, and climate gradients that function over a range spatial temporal scales. Ecosystems from the microbial communities on ice sheet moisture-stressed terrestrial vegetation (and their associated herbivores) to freshwater oligosaline lakes. These ecosystems are linked by dynamic glacio-fluvial-aeolian geomorphic system transports water, geological material, organic carbon nutrients glacier surface adjacent...
Abstract Aim Species are responding to climate change by changing their distributions, creating debate about the effectiveness of existing networks protected areas. As a contribution this debate, we assess whether regional winter abundances and distribution Smew Mergellus albellus , migratory waterbird species listed on Annex I ( EU Birds Directive) that overwinters exclusively in European wetlands, changed during 1990–2011, role global warming driving distributional changes network Special...
Abstract Background Infections of wild birds with highly pathogenic avian influenza (AI) subtype H5N1 virus were reported for the first time in European Union 2006. Objectives To capture epidemiological information on HPAI bird populations through large‐scale surveillance and extensive data collection. Methods Records analysed at level to explore epidemiology AI regard species involved, timing location infections as well applicability different types detection infections. Results In total,...
Between 1 September and 15 November 2017, 48 A(H5N8) highly pathogenic avian influenza (HPAI) outbreaks in poultry holdings 9 H5 HPAI wild bird events were reported within Europe. A second epidemic wave started Italy on the third week of July is still ongoing 2017. The Italian epidemiological investigations indicated that sharing vehicles, personnel close proximity to infected are more likely sources secondary spread a densely populated area. Despite human exposures during outbreaks, no...
We assessed trends in the ecological character of wetlands generally and Ramsar Sites reported 2011, 2014 2017 by Contracting Parties to Convention on Wetlands their national reports. There was more widespread deterioration than improvement generally, with increasingly between 2011 2017. The ecological-character were significantly better those but an Trends worst Africa Latin America Caribbean, recently also Oceania, North Europe. Deterioration Site countries a large average area Sites. This...
Since 2020, the SHOT-SWITCH research project has monitored proportion of wild-shot common pheasants Phasianus colchicus in Great Britain that were killed using lead and non-lead shot. This was set up response to UK shooting rural organisations’ announcement game shooters should make a full voluntary transition from shotgun ammunition by 2025 initiatives retailers wholesalers meat products. In study’s fifth final season (2024/2025), 99% obtained businesses other than Waitrose & Partners...
Increasing abundance of geese in North America and Europe constitutes a major conservation success, but has caused increasing conflicts with economic, health safety interests, as well ecosystem impacts. Potential conflict resolution through single, ‘one size fits all’ policy is hindered by differences species’ ecology, behaviour, population status, contrasting political socio-economic environments across the flyways. Effective goose management requires coordinated application suite tools...
The ‘Ramsar’ Convention on Wetlands was the first of modern era global biodiversity conventions and remains only multilateral environmental agreement focused a single group ecosystem types. At time initial discussions within wetland conservation science community in late 1960s, its ambition unprecedented, with no successful models to draw upon, especially regard novel concepts such as modus for an ‘internationally protected site’. Drawing previously unpublished draft texts, we track...
Abstract Greenland white-fronted geese Anser albifrons flavirostris wintering in Britain and Ireland migrate over the sea for 700–1200 km to stage 3–5 weeks Iceland spring, continuing a similar distance Ice Cap West breeding grounds. During 1969 2012, advanced mean departure date from by 15 days, during which time also they attained threshold fat stores earlier as well departing fatter condition. Over that period, spring-staging shifted consuming underground plant storage organs grazing...
Scientific bird ringing was initiated to study the movements of birds, particularly annual migrants. When a ringed is reported scheme we have location that at two points in time – where and when it found. The collation reports birds (recoveries) allows patterns change with be described. Different methods presenting these simple data been devised over years; initially, aim summarise our knowledge go. Quantitative inference about population behaviour from recovery complicated by several...
There are significant negative effects of exposure to spent lead ammunition on wildlife and human health. A joint statement was issued by nine UK shooting rural organisations 24th February 2020 intended encourage a voluntary transition non-lead shotgun within five years “in consideration wildlife, the environment ensure market for healthiest game products”. We dissected carcasses wild-shot common pheasants Phasianus colchicus sold or offered consumption in Britain season between 1st October...
