Respiratory function of a unit of blood volume in the little auk (Plautus alle) and the arctic tern (Sterna paradisaea)

Comparative Biochemistry and Physiology Part A: Physiology, 1987
The indices of red blood were determined in nestlings and adults of Plautus alle and adults of Sterna paradisaea. All measured parameters varied significantly, but the amount of Hb per unit area of erythrocytes did not change over the nestling development of P. alle. In adult P. alle, S.

Nest defence and predator recognition by Arctic tern (Sterna paradisaea)

2022
In the presented work, I describe the behaviour of Arctic terns (Sterna paradisaea) toward predator species that differ in the threat they represent to them and to their nests. I presented textile dummies of great black-backed gull (Larus marinus), peregrine falcon (Falco peregrinus), common raven (Corvus corax) and common eider (Somateria mollissima),

Effects of habitat on breeding ecology of Arctic Terns Sterna paradisaea Pontoppidan on Machias Seal Island

1992
Previous studies have uncovered interesting differences in a number of reproductive characteristics among Arctic Terns (Stema paradisaea) nesting in different habitats on Machias Seal Island. Over a period of several years (1978-1981), it was found that the birds nesting in inland, grassy habitat had higher hatch and fledge success than those in ...

Diet and foraging movements of sympatric-nesting Arctic Terns (Sterna paradisaea) and Common Terns (Sterna hirundo) on Country Island, Nova Scotia

Sympatrically-nesting seabirds may experience resource competition in various dimensions of the ecological niche, and in response often exhibit niche partitioning as either spatial segregation, dietary segregation, or some combination of the two. Furthermore, as central-place foragers seabirds must efficiently exploit resources away from the colony ...
