چکیده

We suggest that the spatial and temporal patterns of danger arising from the annual migration of birds of prey has important implications for patterns of habitat use and for the evolution of wader annual movement patterns and annual cycles. We discuss how waders might respond to danger by their choice of migration routes, the time of year they choose to migrate, the quantity of fuel they carry, the length of time they spend at staging and stop over sites, the duration of the breeding season and parental care, and the timing and location of feather moult.

Wet Grasslands as a Green Infrastructure for Ecological Sustainability: Wader Conservationin Southern Sweden as a Case Study

Biosphere Reserves aim at being role models for biodiversity conservation. This study focuses on the unsuccessful conservation of waders (Charadrii) on wet grasslands in the Kristianstad Vattenrike Biosphere Reserve (KVBR) in southern Sweden. Predation on nests and young has been proposed as one reason contributing to the decline of waders. We explored this hypothesis by comparing two landscape...

Is breeding of farmland wading birds depressed by a combination of predator abundance and grazing?

Agri-environment schemes have been implemented across Europe to counter biodiversity loss in agricultural landscapes and halt the continual decline of farmland birds, including waders. Such schemes provide financial compensation for changes in agricultural practice, including livestock grazing regimes. Scheme uptake has been variable, partly because farmers believe that other factors, notably p...

Assessment of Landscape Connectivity and Prediction of Migration Corridors for the Baluchistan Black Bear (Ursus thibetanus gedrosianus Blanford, 1877) in the Southeastern Habitats, Iran

The Baluchistan Black Bear (BBB), a critically endangered subspecies (CR), is distributed in the southeastern Iran. Modelling of landscape connectivity of the BBBs among habitat patches can be insightful for the conservation managers working in Iran. Our study was designed to identify the potential corridors among 31 habitat patches of the BBBs in Iran using the circuit theory method. Habitat s...

Use of radio telemetry in studies of shorebirds' past contributions and future directions

The use of radio telemetry in wader studies has grown exponentially in the past decade, and more than 40 species from four different families have been radio-marked. We summarize these studies and find that nearly all of them have used Very High Frequency radio transmitters to study individuals for periods from a few days to a few months. In the past five years, there has been tremendous growth...

The importance of the peatlands of the Upper Volga area as habitats for breeding waders

In the Tver region 31 wader species were recorded and of these, 19 species breed there, 11 species are considered rare and ten of these rare species breed in different peatlands. Golden Plover Pluvialis apricaria and Whimbrel Numenius phaeopus breed only on raised bogs, Marsh Sandpiper Tringa stagnatilis and Great Snipe Gallinago media breed only on fens. Ruff Philomachus pugnax, Redshank Tring...
