Soil from cottongrass (Eriophorum vaginatum) tussock tundra at Eagle Creek, Alaska, was
analyzed with respect to the distribution, abundance, and germination patterns of buried
viable seeds. Seeds of Carex bigelowii, Eriophorum vaginatum, and Ledum palustre were ...

A comparison is made of the species of the above ground vegetation and the buried seeds
in a tussock tundra meadow, northern Alaska. Vegetation types are compared across a
boundary between two habitats which have distinct differences in above ground ...

(1) High densities of Eriophorum vaginatum seedlings were found in various microhabitats
of Alaskan tussock tundra, especially in hepatic mats (<1\tt\% of the tundra), which are
stabilized areas of frost boils. Moss mats had lower seedling densities but, because of ...

Numbers of germinable seeds in soils from four undisturbed communities at an Alaskan
Arctic Coastal Plain site ranged from 70 to 600 m-2 and numbers of distinct taxa were two to
nine. Stratified soils contained more germinable taxa than unstratified soils, suggesting ...

Germinable seed numbers in the surface soil were estimated across three snowbank
gradients in montane tundra of interior Alaska. Vegetation, productivity, and disturbance
change with distance across these gradients. Seed densities are in the range 500 to 1800 ...

Abstract The potential contribution of vertebrate-mediated seed rain to the maintenance of
plant community richness in a High Arctic ecosystem was investigated. We analyzed viable
seed content in dung of the four numerically most important terrestrial vertebrates in ...

Seed plant diversity of alpine tundra of Changbai Mountain has been studied based on
herbarium and literature records and field investigations. There are 146 seed-plants on the
alpine tundra of Changbai Mountains. They are grouped into 94 genera and 34 families. ...

Abstract.--Two species of geese (Chloephaga spp.) are important frugivores and possible
seed dispersers in Tierra del Fuego. In other parts of the world, geese, gulls, swans, and
shorebirds consume fruit regularly and may be seed dispersers. Thus, in habitats where ...
