Abstract Brent geese (called brant in North America) are among the smallest and the most marine of all goose species, and they have very long migration routes between high Arctic breeding grounds and temperate wintering grounds. Like all other geese, brent geese are almost entirely herbivorous. Because of these ecological characteristics they have a high food demand and are strongly dependent on stopover sites to ”refuel” during the migration period. Three subspecies of brent geese are… 
Effect of grazing by Canada geese Branta canadensis on an intertidal eelgrass Zostera marina meadow
Fishing Island, in Portsmouth Harbor on the Maine-New Hampshire border (USA), is the site of an intertidal eelgrass (Zostera marina L.) bed that is part of SeagrassNet, an international program for
Long-term Patterns of Eelgrass (Zostera marina) Occurrence and Associated Herbivorous Waterbirds in a Danish Coastal Inlet
It is suggested that dense eelgrass populations stimulate herbivorous waterbirds whereas top-down control is only likely when abundant bird populations graze on sparse eel Grass populations.
Decline of Canada geese (Branta canadensis) and common goldeneye (Bucephala clangula) associated with a collapse of eelgrass (Zostera marina) in a Nova Scotia estuary
Lower than usual weekly abundances of geese and goldeneye are probably the result of an unusually short residence time in the estuary, rather than a decline in the total number of visiting migrants, due to a dramatic decline in eelgrass.
Impacts of wintering redhead ducks (Aythya americana) on seagrasses in the northern Gulf of Mexico
North American Brant: effects of changes in habitat and climate on population dynamics
We describe the importance of key habitats used by four nesting populations of nearctic brant (Branta bernicla) and discuss the potential relationship between changes in these habitats and population
The contribution of seagrass beds (Zostera noltii) to the function of tidal flats as a juvenile habitat for dominant, mobile epibenthos in the Wadden Sea
Despite drastic diurnal fluctuations of dissolved oxygen at low tide, faunal density in the residual water layer remaining in seagrass canopies at ebb tide was found to be consistently higher than that found in artificially created tide-pool units.
Foraging home ranges of Black Brant Branta bernicla nigricans during spring stopover at Humboldt Bay, California, USA
Foraging home ranges of Black Brant Branta bernicla nigricans (n = 8) were quantified to determine proportional use of available intertidal habitat during spring migration stopover at Humboldt Bay,
Rise in human activities on the mudflats and Brent Geese (Branta bernicla) wintering distribution in relation to Zostera spp. beds: a 30-year study
The results show that establishment of resource protection areas are efficient as conservation measures, and they underline the need for studies of impacts of human activities on resources, in addition to disturbance effects.
Energetic consequences of a major change in habitat use: endangered Brent Geese Branta bernicla hrota losing their main food resource
Flyway-wide declines in Zostera abundance and further reductions in traditional habitats due to climate change give cause to reassess projected population trends and consequent management implications for the East Atlantic flyway population of Light-bellied Brent Geese.


Zostera exploitation by Brent Geese and Wigeon on the Exe Estuary, southern England
Brent Goose and Wigeon feeding behaviour was studied at two Exe intertidal Zostera beds during 1990–1992, to assess the overlap in time and space of these two herbivorous waterfowl, apparently feeding upon the same food resource.
Habitats and tidal accessibility of the marine foods of dabbling ducks and brant in Boundary Bay, British Columbia
Seasonal effects of tides on accessibility might limit sufficient feeding by some waterfowl species in intertidal areas, increasing their reliance on alternative feeding sites.
Expansion of seagrass habitat by the exotic Zostera lapontca. and its use by dabbling ducks and brant in Boundary Bay, British Columbia
The exotic seagrass Zostera japonica was first documented on the Pacific Coast of North America in the late 1950s, and has extensively colonized formerly unvegetated tidal flats and dramatically
Black Brant Winter and Spring-Staging Use at Two Washington Coastal Areas in Relation to Eelgrass Abundance
We monitored numbers of Black Brant (Branta bernicla nigricans) in Washington from fall 1980 through spring 1992 at Willapa Bay, and from fall 1986 through spring 1993 in the Dungeness area. We
Nutrient reserves of premigratory Brant during spring
Brant (Branta bernicla), like other arctic-nesting geese, rely heavily on stored nutrient reserves during reproduction, but must rely on exogenous sources of nutrients because they cannot store enough reserves to fast throughout incubation.
The importance of body reserves accumulated in spring staging areas in the temperate zone for breeding in Dark-bellied Brent Geese Branta b. bernicla in the high Arctic
Measurements of changes in body mass of incubating female Brent Geese, coupled to estimated flying costs showed that body reserves stored in the Wadden Sea were insufficient to accomplish both migration and successful breeding.
Atlantic Brant - human commensalism on eelgrass beds in New Jersey
Atlantic Brant Branta bernicla hrota in Barnegat Bay, New Jersey, have established a commensal feeding relationship with man, which gives the Brant an efficient food gathering opportunity and permits them to exploit Zostera which might otherwise be unavailable to them.
