Abstract. In the Camargue (southern France), drastic changes in wetlands have occurred (notably extension of agriculture and salt extraction) since the 1960s, which affect the resources available to migratory waterbirds. Winter diets of Mallard (Anas platyrhynchos) and Teal (A. crecca) in 2006–2008 were assessed by analyses of gullet contents. Using PCA-based methods, duck diets were described and the main feeding habitats used by each duck species were then determined with a typology… 
Sitting ducks: diet of wintering wildfowl in Lake Tonga, northeast Algeria
TLDR
Diet analysis of five species of Anatidae at Lake Tonga indicated a heavy reliance on seeds, which included a wide variety of aquatic plants, and the type, abundance and frequency of food consumed clearly indicated differences in resource use among the ducks.
Waterfowl foraging in winter-flooded ricefields: Any agronomic benefits for farmers?
TLDR
It is demonstrated that the winter-flooding effect on straw decomposition can be enhanced by waterfowl foraging, hence showing an agronomic benefit from ducks to farmers, however, there was no clear effect in terms of seed bank reduction.
Seed dispersal by dabbling ducks: an overlooked dispersal pathway for a broad spectrum of plant species
TLDR
Internal seed dispersal by dabbling ducks appears to be a major dispersal pathway for a far broader spectrum of plant species than previously considered.
Habitat and resource use by waterfowl in the northern hemisphere in autumn and winter
A particular aim of avian ecologists, especially those studying waterfowl Anatidae, in the 20th and early 21st centuries has been to elucidate how organisms use habitats and intrinsic resources to
Seed density and waterfowl use of rice fields in Camargue, France
TLDR
Harvested rice fields have a great potential as nocturnal foraging habitat for wintering ducks in the Camargue and should be avoided and flooding promoted to better allow ducks to use these fields.
Diversity patterns and seasonal variation of the waterbird community in Mediterranean wetlands of Northeastern Algeria
TLDR
The seasonal structure of waterbird communities indicates highly dominated assemblages manifesting themselves in reduced species diversity and increased dominance of certain species.
Movements, Home-Range Size and Habitat Selection of Mallards during Autumn Migration
TLDR
The fact that autumn-staging migratory mallards have a well-developed diel activity pattern tightly linked to the use of specific habitats has implications for wetland management, hunting and conservation, as well as for the epidemiology of diseases shared between wildlife and domestic animals.
Becoming more sedentary? Changes in recovery positions of Mallard Anas platyrhynchos ringed in the Camargue, France, over the last 50 years
Earlier studies from central and northern Europe have found a shortening of the ring recovery distance in Mallard Anas platyrhynchos, which was generally attributed to climate change leading to a
From introduction to nuisance growth: a review of traits of alien aquatic plants which contribute to their invasiveness
TLDR
The existing knowledge on the biology of 21 IAAPs is summarized to highlight traits that are linked to their invasive success, including dispersal and growth patterns, allelopathy and herbivore defence.

Distribution of submerged macrophytes in the Camargue in relation to environmental factors
TLDR
The hydrological regime and the salinity appeared to be the main factors controlling the abundance of the different species, and the management of the marshes in the Camargue, which is carried out using these two controlling factors.

Average Mass of Seeds Encountered by Foraging Dabbling Ducks in Western Europe
TLDR
A reference table for seed mass of 200 western European plant taxa frequently encountered by foraging dabbling ducks is provided, to aid managers and scientists in assessing the importance of seed food resources at different sites and during different parts of the annual cycle.
The role of migratory ducks in the long‐distance dispersal of native plants and the spread of exotic plants in Europe
TLDR
Migratory ducks are important vectors for both terrestrial and aquatic plant species, even those lacking the fleshy fruits or hooks typically used to identify seeds dispersed by birds, according to a literature review.

TLDR
Understanding the trophic-habitat relationships of diving ducks in coastal wintering areas will give managers a better understanding of the ecological effects of future environmental changes.
