Nationally important wintering populations of up to 2700 Pochard Aythya ferina and 2000 Tufted Duck A. fuligula feed around Salford Docks in the upper reaches of the Manchester Ship Canal. The system is grossly organically polluted and devoid of aquatic macrophytes, but holds high densities of oligochaetes and other pollution-tolerant invertebrates. The species fed together and differences in feeding distributions were more apparent between day and night than they were between species or winter… 

Differential Waterbird Population Dynamics After Long-Term Protection: The Influence of Diet and Habitat Type

The results suggest that growth rates alone are poor descriptors of population fluctuations, especially for birds and other vagile taxa, and that it is more appropriate to interpret trends when considering natural regions spatially, and when growth rates are analysed within the time scale of the theoretical logistic curve.

Response of aquatic invertebrates to vegetation management and agriculture

Wetland managers rely on a variety of vegetation management techniques to set back plant succession, enhance seed production, create hemi-marsh conditions, and reduce the coverage of invasive plants

Feeding behaviour of Lumbriculus variegatus as an ecological indicator of in situ sediment contamination

This chapter discusses feeding inhibition as a bioassay endpoint in in situ bioassays for sediment assessment, and selection of LUMBRICULUS VARIEGATUS as an in SITU bIOASSAY ENDPOINT.

The environmental toxicology of zinc oxide nanoparticles to the oligochaete

This thesis investigated the potential toxicity of zinc oxide nanoparticles (NPs) and bulk particles (both with and without organic matter (HA)) to the Californian Blackworm, Lumbriculus variegatus.

The indirect effects of increased nutrient inputs on birds in the UK: a review



Pochard Aythya ferina use of chironomid-rich feeding habitat in winter

It would appear that Pochard prefer to feed in shallow water and can select prey-rich areas, thus maximizing their food intake whilst minimizing their energy expenditure.

Food Consumption of Diving Ducks Wintering at the Coast of South Sweden in Relation to Food Resources

The food choice of diving ducks in the nonbreeding season and their exploitation of the potential food resources were investigated in an area on the Scania coast of the Sound (Oresund) in 1965/66 and

Winter feeding ecology of scaup and common goldeneye in Michigan

There is little information available to develop effective management plans or to assess the effects of further alteration of wintering habitats, and Owen and Reinecke and Prince suggested energy expenditure for thermoregulation was high for waterfowl wintering at northern latitudes.

Variation in winter wildfowl numbers on gravel pit lakes at Great Linford, Buckinghamshire, 1974–79 and 1984–91, with particular reference to the effects of fish removal

There was a large increase in numbers of wildfowl using a 17 ha lake after the fish populations were removed in November 1987, and it is suggested that these changes were related to demonstrated increases in benthic invertebrates post-fish removal.

Wintering Tufted Ducks Aythya fuligula diving for zebra mussels Dreissena polymorpha balance feeding costs within narrow margins of their energy budget

Water efflux and daily energy expenditure (DEE) were measured using doubly-labelled water and imply that food availability and water temperature are important attributes to winter distributions of diving ducks.

Differential use of fresh water environments by wintering waterfowl of coastal Texas

This study was conducted to determine how feeding flocks of wintering waterfowl coexisted in feeding site selection, what environmental factors that were measured were the most important in certain aspects of niche separation, and how the niches were arranged in the aquatic community at the study site.

Impact of Disturbance on Waterfowl Wintering in a UK Dockland Redevelopment Area

Abstract One of the UK's largest flocks of pochard Aythya ferina and tufted duck A. fuligula winters in Manchester's busy dockland redevelopment area. I examined the effects of human disturbance on

Resource Utilization Pattern and Guild Structure in a Waterfowl Community

It is concluded that competition does not play an important role in structuring the waterfowl community studied and segregation of the species in the two-dimensional niche space reflects group-specific adaptations to utilize resources intrinsically in different ways.

Disturbance of overwintering wildfowl by anglers at two reservoir sites in South Wales

Studies of bird distribution and behaviour at 2 reservoir sites in South Wales showed different degrees of disturbance by anglers. During October and March at Llandegfedd Reservoir, the distributions
