Breeding waterfowl, habitat diversity and food diversity were studied in 31 boreal lakes in Finland and Sweden. Lakes were 2-48 hectares in size, and had zero to eleven waterfowl species each. In a ... 
Abundance–distribution relationships on interacting trophic levels: the case of lake‐nesting waterfowl and dytiscid water beetles
To compare patterns in local abundance, regional distribution and body size in waterfowl and dytiscid beetles sampled from the same lakes.
Species–area relationship of Neotropical waterbird assemblages in remnant wetlands: looking at the mechanisms
Aim  We investigated the relative role of area, isolation, microhabitat diversity and number of individuals as explanatory factors defining the richness of waterbirds in wetland remnants.
Nest site selection by Holarctic waterfowl: a multi-level review
Because of birds’ mobility, behaviour and many species’ migratory nature, they select repeatedly and spatially among habitats and have been central figures in studies of avian breeding habitat sele
Species Diversity, Abundance and Brood Numbers of Breeding Waterbirds in Relation to Habitat Properties in an Agricultural Watershed
Land-use changes and the resulting habitat degradation have been regarded as the most important known causes of waterfowl population declines. We assessed the habitat requirements of waterbirds,
Climate-induced lake drying causes heterogeneous reductions in waterfowl species richness
ContextLake size has declined on breeding grounds for international populations of waterfowl.ObjectivesOur objectives were to (1) model the relationship between waterfowl species richness and lake
Diversity of terrestrial isopods in the northern Tunisian wetlands
A highly significant positive relationship between species richness and both humidity and altitudinal gradient was described and the dendrogram of similarities showed a divergence of the lagoons compared to the remaining wetland types.
Population change in breeding boreal waterbirds in a 25‐year perspective: What characterises winners and losers?
Diet turned out to be a strong candidate for an important driver of population change, as supported by a general decrease of invertivores and a concomitant increase of large herbivores.
Diversity of waterbirds wintering in Douz wetlands (south Tunisia): factors affecting wetland occupancy and species richness
Understanding the environmental factors shaping wetland attractiveness for waterbirds is an important question in wetland ecology and for conservation purposes. However, detailed data from numerous
Tunisian man‐made wetlands as alternative habitats for waterbirds and their role for conservation
Investigating Tunisian artificial wetlands revealed a significant carrying capacity and refuge serving for the conservation of numerous wintering and endangered waterbird species of high nature conservation value, the White-headed Duck Oxyura leucocephala that has been observed with relatively high numbers representing more than 40% of the assessed Tunisian–Algerian population.


Factors affecting species number and density of dabbling duck guilds in North Europe
We addressed how species number and pair density in guilds of co-existing species is related to habitat structure, and to the abundance and diversity of food resources. using the assemblage of seve
Species Richness in Plant Communities
Knowledge of species richness is important for establishing priorities in conservation planning and management. Patterns of species richness in four exceptionally species-rich plant communities and
Breeding Bird Community Densities and Species Richness in Lakes
Multiple regression analysis revealed that breeding bird community densities in eleven south Swedish lakes were positively correlated both with total phosphorus concentrations of the water and with
Randomness, Area, and Species Richness
Analysis of censuses of breeding birds on islands in Pymatuning Lake, a reservoir at the Pennsylvania-Ohio border, yields the conclusion that for these islands the variation of the number of resident avian species with island size is that which one would expect if the birds were distributed randomly.
Breeding Birds of Isolated Woodlots: Area and Habitat Relationships.
Results from Illinois support previous conclusions that species that breed in forest interior habitat and winter in the tropics are most likely to be adversely affected by a reduction in forest habitat and show that bird communities in isolated tracts of forest are not random assemblages, but rather that species found in smaller woodlots are subsets ofspecies found in larger forests.
Patterns in the Species Composition and Richness of Fish Assemblages in Northern Wisconsin Lakes
Fish assemblage structure, and factors and mechanisms appearing important in the ecological maintence of these structures, were examined for 18 small lakes in northern Wisconsin during summer and
Nest-site distribution and overland brood movements of northern pintails in Alberta
The distance of pintail nests from water was determined, and the hypothesis that male pursuit flights cause hens to nest far from water to avoid male-chasing was repudiated in favor of one that such behavior reduces nest predation.
Lake selection by Goldeneye ducklings in relation to the abundance of food
The overland movements from lake to lake by non-fledged Goldeneye ducklings are correlated with the food supply in different lakes and some aspects of the evolution of this behaviour with reference to the abundance of food are mentioned.
Predator-prey size relationships in North American dabbling ducks
Using published taxonomic diet lists for seven species of ducks, measurements of bill morphology from museum specimens, and "handbook" data on the sizes and caloric density of invertebrates, prey size distributions were found to differ among species.
