Fatty acid composition of the adipose tissue of polar bears and of their prey: ringed seals, bearded seals and harp seals
Download2003
Grahl-Nielsen, O., Lydersen, C., Wiig, Ø., Kovacs, K., Derocher, A.E., Andersen, M.
Polar bears Ursus maritimus are predators of phocid seals, but they also forage opportunistically on a variety of other species. In the Barents Sea—Svalbard area, their diet is thought to consist almost exclusively of ringed seals Phoca hispida, bearded seals Erignathus barbatus and harp seals P....

Feather mites of the genus Proterothrix Gaud (Astigmata: Proctophyllodidae) from parrotbills (Passeriformes: Paradoxornithidae) in China.
Download2009
Three new species of the feather mite genus Proterothrix Gaud, 1968 (Proctophyllodidae: Pterodectinae) are reported from parrotbills (Passeriformes: Paradoxornithidae) in China. We describe Proterothrix paradoxornis n. sp. from Paradoxornis webbianus (type host) and Par. alphonsianus, P....

Fecal Pellet Counts as a Technique for Monitoring an Alpine-Dwelling Social Rodent, the Hoary Marmot (Marmota caligata)
Download2004
Karels, T. J., Koppel, L., Hik, D. S.
We evaluated fecal pellet counts as an index of hoary marmot (Marmota caligata) social group size in order to develop a simple, inexpensive method for monitoring population change of a widely distributed, but poorly studied alpine mammal. Fecal pellet counts were conducted in three separate...

Abstract: Lees (Proc Zool Soc Lond 121: 759-772, 1952) concluded that the ixodid tick Ixodes ricinus grows endocuticle during the slow but not during the rapid, phase of engorgement, a conclusion supported by Andersen and Roepstorff (Insect Biochem Mol Biol 35:1181-1188, 2005) for the same...

Fertilization effects on interactions between above-and belowground competition in an old field
Download1999-01-01
Recent theoretical and experimental studies have addressed whether the relative importance of aboveground and belowground competition changes along gradients of biomass productivity. Results have been contradictory, with some researchers finding a decrease in the importance of belowground...
