Derocher, Andrew E., Skaare, Janneche U., Jenssen, Bjørn Munro, Sørmo, Eugen G., Lie, Elisabeth, Braathen, Marte, Wiig, Øystein
We studied the relationships between polychlorinated biphenyls (PCBs) and thyroid hormones (THs) and retinol within two groups of female polar bears (Ursus maritimus), females with cubs of the year (FWCOY) and females without cubs of the year (FWOCOY), and within a group of males. Concentrations...

Burnham, D. A., Bakker, R. T., Currie, P. J., Ostrom, J. H., Kraig, L. D., Zhou, Z.
We describe a small dromaeosaurid dinosaur. Bambiraptor feinbergi n. gen. and n. sp., based upon a nearly complete fossil skeleton from the Two Medicine Formation (Upper Cretaceous) of Montana. Widely known as Bambi, this skeleton is a well-preserved subadult that is about 75 percent adult size....

Reproductive Biology and Evidence for Water Dispersal of Teliospores in Chrysomyxa weirii, a Microcyclic Spruce Needle Rust
Download2000
Hiratsuka, Yasuyuki, Crane, Patricia E., Currah, Randolph S.
Chrysomyxa weirii (Uredinales) is the only autoecious, microcyclic species of Chrysomyxa occurring in North America. The telia form on second-year needles of spruce, causing premature needle loss. The morphology of the telia was studied in herbarium specimens from diverse locations, and the...

Reproductive biology of the Cerro Cuadrado (Jurassic) fossil conifers: Pararaucaria patagonica Wieland
Download1977
Seventy-two silicified cone specimens of Pararaucaria patagonica Wieland from the Cerro Cuadrado (Jurassic) petrified forest in Patagonia were studied by use of thin sections and reflected light. Traces from the cone axis stele to the bract and ovuliferous scale are separate at their origins. In...

Schneider, Richard R, Bayne, Erin M
Ecosystem distributions are expected to shift as a result of global warming, raising concerns about the long-term utility of reserve systems based on coarse-filter ecosystem representation. We tested the extent to which proportional ecosystem representation targets would be maintained under a...

Residual tree retention ameliorates short-term effects of clear-cutting on some boreal songbirds
Download2001
Hannon, S. J., Norton, M. R., Tittler, R.
Abstract: Retention of residual trees in \"cutblocks,\" logged blocks of forest, has been proposed as a method to conserve songbirds in landscapes fragmented by clear-cut logging. We examined songbird communities in the boreal mixed-wood forest of Alberta, Canada, to investigate the effect on...

Resistance of some cultivated Brassicaceae to infestations by Plutella xylostella (Lepidoptera: Plutellidae)
Download2007
Sarfraz, M., Dosdall, L. M., Keddie, B. A.
Abstract: Selecting insect-resistant plant varieties is a key component of integrated management programs of oligophagous pests such as diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), but rigorous research on important life history parameters of P. xylostella in relation to...
