Summary The Numeniini is a tribe of 13 wader species (Scolopacidae, Charadriiformes) which seven are Near Threatened or globally threatened, including two Critically Endangered. To help inform conservation management and policy responses, we present the results an expert assessment threats that members this taxonomic group face across migratory flyways. Most increasing in intensity, particularly non-breeding areas, where habitat loss resulting from residential commercial development,...
No longer a safe haven Many biological patterns have latitudinal component. One long-recognized pattern is that predation rates are higher at lower latitudes. This may explain why many migratory birds travel thousands of miles from the tropics to poles breed. Looking across records, Kubelka et al. found climate change seems altered this fundamental pattern. In shorebirds, least, on nests now in Arctic than tropics. Science , issue p. 680
About 50 species of shorebirds breed in the Arctic, where they constitute most characteristic component tundra avifauna. Here, we review impact weather and climate on breeding cycle based extensive studies conducted across Arctic. Conditions for are highly variable among species, sites regions, both within between continents.

Abstract Poor knowledge of animal behaviour impedes understanding ecology and evolution reduces human appreciation the natural world. We call this ‘ethological shortfall’, parallel to Linnean other shortfalls in conservation biology systematics. analysed sound recordings breeding spoon-billed sandpipers (Scolopacidae: Calidris pygmaea ), a critically endangered species. Sixteen years field research, focused short-term study, provided material for our study. All species’ calls are unique...
ABSTRACT Shorebird populations are declining across the world due to factors such as habitat loss and climate change. Identification of shorebird migration routes important stopover sites can facilitate implementation strategic effective conservation measures. Using a satellite transmitter, we successfully tracked one Grey Plover ( Pluvialis squatarola ) from its wintering grounds in Singapore north along East Asian‐Australasian Flyway (EAAF) breeding located east Taymyr Peninsula...
Recent observations of body size declines in animal populations have given rise to discussions whether or not this is related climate change-induced temperature increases, with which the changes would follow Bergmann's rule. Although debate ongoing, limited thermal benefits currently observed reductions make it unlikely that increase shapes a direct selection pressure. Food constraints during early-life development, could be caused by mismatches between available resources and energetic...
Lemming population cycles in the Arctic have an important impact on food web, indirectly also affecting breeding success Arctic‐nesting birds through shared predators. Over last two decades lemming changed amplitude and even disappeared parts of Arctic. To examine large scale effect these recent changes we re‐analysed published data from East Atlantic Flyway (EAF), where a relationship between wader was earlier found, new waders Asian–Australasian (EAAF). We found that 1) any long‐term...
Abstract Aim Over the last two decades, thousands of northward migrating ruffs (Philomachus pugnax) have disappeared from western European staging sites. These migratory were partly temperate breeding birds, but most individuals head towards Eurasian Arctic tundras where 95% global population breeds. This regional decline may represent either: (1) local loss birds in Europe, (2) a decline, (3) shift(s) distribution or (4) combination these. Location Northern Eurasia. Methods To put declines...
Due to the ‘double‐clutch’ mating system found in arctic‐breeding Little Stint Calidris minuta , each parent cares for a clutch and brood alone. The resulting constraint on feeding time, combined with cold climate small body size, may cause energetic bottlenecks. Based notion that mass stores birds serve as an ‘insurance’ transient periods of negative energy balance, but entail certain costs well, vary relation climatic conditions stage breeding cycle. We studied Stints geographical...
The Greenlandic and west-central Siberian breeding populations of Sanderlings Calidris alba are separated by ca. 2000 km during the season, but mix in Europe to some extent migration. However, number that spend non-breeding season along East Atlantic Flyway (extending from western South Africa), if any, is unknown. Although both considered part nominate subspecies C. a. based on morphology, population structure has yet be described with molecular methods. We examined genetic differentiation...
In seasonal environments subject to climate change, organisms typically show phenological changes. As these changes are usually stronger in at lower trophic levels than those higher levels, mismatches between consumers and their prey may occur during the consumers' reproduction period. While some species a mismatch induces reductions offspring growth, this is not always case. This variation be caused by relative strength of mismatch, or mitigating factors like increased temperature-reducing...
Present-day ecology and population structure are the legacies of past climate habitat perturbations, this is particularly true for species that widely distributed at high latitudes. The red knot, Calidris canutus, an arctic-breeding, long-distance migratory shorebird with six recognized subspecies defined by differences in morphology, migration behavior, annual cycle phenology, a global distribution thought to have arisen just since last glacial maximum (LGM). We used nextRAD sequencing...
Abstract In migratory animals, high mobility may reduce population structure through increased dispersal and enable adaptive responses to environmental change, whereas rigid routines predict low dispersal, structure, limited flexibility respond change. We explore the global phylogeographic history of bar‐tailed godwit, Limosa lapponica , a shorebird known for making longest non‐stop flights any landbird. Using nextRAD sequencing 14,318 single‐nucleotide polymorphisms scenario‐testing in an...
Five subspecies of Dunlins (Calidris alpina) that breed in Beringia are potentially sympatric during the non-breeding season. Studying their ecology this period requires techniques to distinguish individuals by subspecies. Our objectives were determine (1) if five morphometric measures (body mass, culmen, head, tarsus, and wing chord) differed between sexes among (C. a. actites, arcticola, kistchinski, pacifica, sakhalina), (2) these differences sufficient allow for correct classification...

Previous studies have shown that preen wax composition in some sandpipers shifts from the usual monoesters to diesters during breeding season, possibly reduce ability of mammalian predators find nests using olfactory cues. To investigate further relationship between incubation and secretion, we examined seven sandpiper species with different patterns (species which both sexes incubate, only males incubate females incubate). During period, diester was secreted almost exclusively by incubating...
Abstract Waterfowl (Anseriformes) and shorebirds (Charadriiformes) are the most common wild vectors of influenza A viruses. Due to their migratory behavior, some may transmit disease over long distances. Migratory connectivity studies can link breeding nonbreeding grounds while illustrating potential interactions among populations that spread diseases. We investigated Dunlin ( C alidris alpina ), a shorebird with subspecies C. a. arcticola ) migrates from areas endemic avian in eastern Asia...

We report first formal estimate of its global population size, combining mark–resighting number leg-flagged individuals alive autumn 2014 with an proportion birds flags from scan surveys conducted during same period at migration stop-over site on Jiangsu coast China. world breeding sandpipers was 210–228 pairs...
Abstract Correct assessment of species limits and phylogenetic relationships is a prerequisite for studies in ecology evolution. Even well-studied groups such as birds, delimitation often remains controversial. Traditional avian taxonomy usually based on morphology, which might be misleading because the contingent nature evolutionary diversification. The sand plover complex (genus Charadrius) may an example wherein 2 Lesser Sand Plover C. mongolus subspecies have been proposed to comprise...
Determining the dynamics of where and when individuals occur is necessary to understand population declines identify critical areas for populations conservation concern. However, there are few examples a spatially temporally explicit model has been used evaluate migratory bird across its entire annual cycle.
