We estimated the size of 30 defined populations geese wintering in Western Palearctic (including five released or reintroduced three species). Fourteen were accurately from almost full count coverage robust sampling and ten well based on more than 50% their total being counted. An 5.03 million wintered January 2009, up 3.10 1993. Only two numbered less 10,000 birds (Scandinavian Lesser White-fronted Goose Svalbard/Greenland Light-bellied Brent Goose, former critically small within restricted...
According to migration theory and several empirical studies, long‐distance migrants are more time‐limited during spring should therefore migrate faster in than autumn. Competition for the best breeding sites is supposed be main driver, but timing of often also influenced by environmental factors such as food availability wind conditions. Using GPS tags, we tracked 65 greater white‐fronted geese Anser albifrons migrating between western Europe Russian Arctic autumn over six different years....
Many migratory herbivores seem to follow the flush of plant growth during migration in order acquire most nutrient‐rich plants. This has also been hypothesized for arctic‐breeding geese, but so far no test this so‐called green wave hypothesis performed at individual level. During four years, a total 30 greater white‐fronted geese Anser albifrons was tracked using GPS transmitters, which 13 yielded complete spring tracks. From those birds we defined stopover sites and related date arrival...
Ecological “big data” Human activities are rapidly altering the natural world. Nowhere is this more evident, perhaps, than in Arctic, yet region remains one of most remote and difficult to study. Researchers have increasingly relied on animal tracking data these regions understand individual species' responses, but if we want larger-scale change, need integrate our understanding across species. Davidson et al. introduce an open-source archive that currently hosts 15 million location points...
Abstract Migratory species experience various conditions and events throughout their annual cycle that influence spatial demographic dynamics. To understand these dynamics, it is essential to describe the origin destination of individuals. connectivity, which defined as geographic linkage between populations across cycle, increasingly incorporated in population models relate trends environmental variables at different stages cycle. However, such information on migratory movements obtained...
ABSTRACT The population of long‐tailed ducks Clangula hyemalis has declined dramatically since the 1990s at species' most important wintering area, Baltic Sea. It is unclear if this represents a real decline flyway level or merely northward shift in range, with part moving from Sea to rarelysurveyed ice‐free Arctic waters. To investigate area choice and individual repeatability, we deployed light‐level loggers on female three breeding sites Western Russian across two annual cycles, 2017...
ABSTRACT In the current warming climate, many organisms in seasonal environments advance their timing of reproduction to benefit from resource peaks earlier spring. For migrants, potential may be constrained by migration strategies, notably ability arrival at breeding grounds. Recent studies show various changes including wintering closer grounds, departure grounds or faster travels spending less time stopover sites. However, whether such lead remains an open question. We studied and 12...
The biodiversity working group of the Arctic Council has developed pan-Arctic monitoring plans to improve our ability detect, understand and report on long-term change in biodiversity. fox (Vulpes lagopus) was identified as a target future because its circumpolar distribution, ecological importance reliance ecosystems. We provide first exhaustive survey contemporary programmes, describing 34 projects located eight countries. Monitored populations covered equally four climate zones species’...
We present an algorithmic framework for criteria-based segmentation of trajectories that can efficiently process a large class criteria. Criteria-based is the problem subdividing trajectory into small number parts such each part satisfies global criterion. Our handle criteria are stable, in sense these do not change their validity along very often. This includes both increasing and decreasing monotone takes O(n log n) time preprocessing computation, where n data points. It surpasses two...
Abstract Significant population growth of some European goose populations has led to initiatives implement management at the flyway level. Understanding migration routes and spatiotemporal distribution is crucial for successful coordinated migratory species such as geese. In this study, we describe movements across entire annual cycle in 76 Greylag geese ( Anser anser ) fitted with GPS tracking devices five catch sites Sweden. We show that breeding Sweden still use a NE-SW path. However,...
Abstract Escalating conflicts between grassland farming and wintering geese in northern Germany stimulated a long‐term study order to promote fair workable system of compensation harvest loss. Between 1996 2018 standardized experiments were carried out quantify changes yield loss herbage quality. Simultaneously, we weekly monitored the number relate losses goose numbers identify impact different species. Exclosure established on conventionally managed grasslands. The investigated fields...
Wild birds are considered a potential reservoir or carrier of viral diseases and may therefore play role in the epidemiology economically important zoonotic diseases. In 2001 2002, survey with special emphasis on virus isolation migrating waders some other were conducted. one most inland resting sites for migratory waterfowl, tracheal cloacal swabs collected from 465 representing 19 different species, 165 that not captured purpose. A total 42 avian viruses isolated, 34 these identified as...
Small rodents with multi-annual population cycles strongly influence the dynamics of food webs, and in particular predator-prey interactions, across most tundra biome. Rodents are however absent from some arctic islands, studies on performance predators under such circumstances may be very instructive since rodent have been predicted to collapse a warming Arctic. Here we document for first time how three normally rodent-dependent predator species—rough-legged buzzard, fox red – perform...
For the conservation and management of migratory species that strongly decrease or increase due to anthropological impacts, a clear delineation populations quantification possible mixing (migratory connectivity) is crucial. Usually, population exchange in only studied breeding wintering sites, but we considered whole annual cycle order determine important stages sites for an Arctic migrant. We used 91 high resolution GPS tracks Western Palearctic greater white-fronted geese (Anser A....
Many migratory animals travel in large social groups. Large, avian migrants that fly V‐formations were proposed do so for energy saving by the use of up‐wash following individuals and regularly change leadership. As groups have been rather homogeneous previous work, we aimed to explore leadership its flight mechanics consequences an extremely heterogeneous case migration, namely spring migration goose families. In families experience group members differs strongly inclusive fitness may be...
Abstract In recent decades, conflict between geese and agriculture has increased. Management practices to limit this include concentrating in protected areas, derogation shooting or population reduction. To justify such management, we need understand their effects on goose‐related damages, which requires an understanding of how yield loss is influenced by goose abundance species interactions. We combined data from monthly counts GPS‐tracked estimate grazing pressures barnacle, white‐fronted...
Abstract In the present Anthropocene, wild animals are globally affected by human activity. Consumer fireworks during New Year (NY) widely distributed in W‐Europe and cause strong disturbances that known to incur stress responses animals. We analyzed GPS tracks of 347 migratory geese four species eight NYs quantifying effects on individuals. show that, parallel with particulate matter increases, night NY flew average 5–16 km further 40–150 m higher, more often shifted new roost sites than...
EU member countries and the UK are currently installing numerous offshore windfarms (OWFs) in Baltic North Seas to achieve decarbonization of their energy systems. OWFs may have adverse effects on birds; however, estimates collision risks barrier for migratory species notably lacking, but essential inform marine spatial planning. We therefore compiled an international dataset consisting 259 migration tracks 143 Global Positioning System-tagged Eurasian curlews (Numenius arquata arquata) from...
Abstract Background The long-tailed duck ( Clangula hyemalis ) was categorized as ´Vulnerable` by the IUCN after a study revealed rapid wintering population decline of 65% between 1992–1993 and 2007–2009 in Baltic Sea. As knowledge about European duck’s life cycle movement ecology is limited, we investigate its year-round spatiotemporal distribution patterns. Specifically, aimed to identify grounds, timing migration staging this via light-level geolocation. Results Of 48 female ducks tagged...
The following glossary of terms related to the European agricultural landscape shall serve as a common basis for all parties, working in or on landscapes. Some are quite and sometimes used our every day language, but they often have different meanings particular countries. These differences may be result varying linguistic developments, history traditions. contains 40 seven languages; English, Dutch, Estonian, French, German, Hungarian, Spanish. Each term begins with an English definition,...
Regular, long-distance migrations of thousands animal species have consequences for the ecosystems that they visit, modifying trophic interactions and transporting many non-pathogenic pathogenic organisms. The spatial structure dynamic properties population flyways largely determine those transport effects, but are yet poorly studied. As a basis, we propose periodic Markov model on migration network breeding, stopover wintering sites to formally describe process level. From seasonally...
In western Europe, the majority of wild goose populations have increased exponentially over last decades. Such increase is source many socio–ecological conflicts. The need for coordinated management actions to handle goose-related conflicts at European scale has led establishment a specific Goose Management Platform (EGMP) under auspices Agreement on Conservation African–Eurasian Migratory Waterbirds (AEWA). northwest/south-west (NW/SW) population greylag Anser anser been considered as...
