Incompletely informed shorebirds that face a digestive constraint maximize net energy gain when exploiting patches.
Foragers that feed on hidden prey are uncertain about the intake rate they can achieve as they enter a patch. However, foraging success can inform them, especially if they have prior knowledge aboutExpand

Hampered Foraging and Migratory Performance in Swans Infected with Low-Pathogenic Avian Influenza A Virus
It is increasingly acknowledged that migratory birds, notably waterfowl, play a critical role in the maintenance and spread of influenza A viruses. In order to elucidate the epidemiology of influenzaExpand

A Three-Stage Symbiosis Forms the Foundation of Seagrass Ecosystems
Ancient Associations Submarine seagrass meadows are critical to fisheries and coastline protection and provide feeding grounds for many endangered species, including dugongs and turtles, and serve asExpand

Foraging in a tidally structured environment by Red Knots (Calidris canutus): ideal, but not free.
Besides the "normal" challenge of obtaining adequate intake rates in a patchy and dangerous world, shorebirds foraging in intertidal habitats face additional environmental hurdles. The tide forcesExpand

Avian herbivory: an experiment, a field test, and an allometric comparison with mammals.
Mechanistic studies on herbivore functional responses have largely taken place in mammals; very little has been done in herbivorous birds so far. Here we aim to fill that gap by experimentallyExpand

Body shrinkage due to Arctic warming reduces red knot fitness in tropical wintering range
Consequences conferred at a distance Migratory animals have adapted to life in multiple, sometimes very different environments. Thus, they may show particularly complex responses as climates rapidlyExpand

Reinterpretation of gizzard sizes of red knots world-wide emphasises overriding importance of prey quality at migratory stopover sites
The size of digestive organs can be rapidly and reversibly adjusted to ecological circumstances, but such phenotypic flexibility comes at a cost. Here, we test how the gizzard mass of a long-distanceExpand

Shellfish Dredging Pushes a Flexible Avian Top Predator out of a Marine Protected Area
There is a widespread concern about the direct and indirect effects of industrial fisheries; this concern is particularly pertinent for so-called “marine protected areas” (MPAs), which should beExpand

Scaling up ideals to freedom: are densities of red knots across western Europe consistent with ideal free distribution?
Local studies have shown that the distribution of red knots Calidris canutus across intertidal mudflats is consistent with the predictions of an ideal distribution, but not a free distribution. Here,Expand

Cost-benefit analysis of mollusc-eating in a shorebird II. Optimizing gizzard size in the face of seasonal demands
SUMMARY Aiming to interpret functionally the large variation in gizzard masses of red knots Calidris canutus, we experimentally studied how the digestive processing rate is influenced by the size ofExpand
