Molecular methods for discriminating taxa, monitoring species, and assessing fungal diversity Molecular methods for discriminating taxa, monitoring species, and assessing fungal diversity
Exiting new molecular approaches that allow investigators to assess fungal biodiversity directly are being developed. These approaches are still in their infancies, but they are developing rapidly. The following papers provide an introduction to this burgeoning field of study: Bohannan and Hughes (2003), Cooksey (1997), Jumpponen (2003), Landeweert et al. (2003), Nikolchva et al. (2003)...

Migration and rearing histories of chinook salmon (Oncorhynchus tshawytscha) determined by ion microprobe Sr isotope and Sr/Ca transects of otoliths Migration and rearing histories of chinook salmon (Oncorhynchus tshawytscha) determined by ion microprobe Sr isotope and Sr/Ca transects of otoliths
Strontium isotope and Sr/Ca ratios measured in situ by ion microprobe along radial transects of otoliths of juvenile chinook salmon (Oncorhynchus tshawytscha) vary between watersheds with contrasting geology. Otoliths from ocean-type chinook from Skagit River estuary, Washington, had prehatch regions with 87Sr/86Sr ratios of ~0.709, suggesting a maternally inherited marine signature...

Persistence of identifiable remains of white sturgeon juveniles in digestive tracts of northern pikeminnow Persistence of identifiable remains of white sturgeon juveniles in digestive tracts of northern pikeminnow
Juvenile white sturgeon, Acipenser transmontanus, have not been commonly identified as prey items in digestive tracts of fishes collected in the wild. In particular, the diet of northern pikeminnow, Ptychocheilus oregonensis, an abundant Pacific Northwest freshwater predator which has been widely studied, has not included juvenile white sturgeon. To aid in interpreting these results and...

Ecological and political issues surrounding decommissioning of offshore oil facilities in the Southern California Bight Ecological and political issues surrounding decommissioning of offshore oil facilities in the Southern California Bight
To aid legislators, resource managers, and the general public, this paper summarizes and clarifies some of the issues and options that the federal government and the state of California face in decommissioning offshore oil and gas production platforms, particularly as these relate to platform ecology. Both local marine ecology and political climate play a role in decommissioning offshore...

Quantitative expression profiling of immune response genes in rainbow trout following infectious haematopoietic necrosis virus (IHNV) infection or DNA vaccination Quantitative expression profiling of immune response genes in rainbow trout following infectious haematopoietic necrosis virus (IHNV) infection or DNA vaccination
Infectious haematopoietic necrosis virus (IHNV) is a well-studied virus of salmonid fishes. A highly efficacious DNA vaccine has been developed against this virus and studies have demonstrated that this vaccine induces both an early and transient non-specific anti-viral phase as well as long-term specific protection. The mechanisms of the early anti-viral phase are not known, but...

Chromosome numbers and karyotype evolution in holoparasitic Orobanche (Orobanchaceae) and related genera Chromosome numbers and karyotype evolution in holoparasitic Orobanche (Orobanchaceae) and related genera
Chromosome numbers and karyotypes of species of Orobanche, Cistanche, and Diphelypaea (Orobanchaceae) were investigated, and 108 chromosome counts of 53 taxa, 19 counted for the first time, are presented with a thorough compilation of previously published data. Additionally, karyotypes of representatives of these genera, including Orobanche sects. Orobanche and Trionychon, are reported...

Critical swimming speeds of wild bull trout Critical swimming speeds of wild bull trout
We estimated the critical swimming speeds (Ucrit) of wild bull trout at 6??, 11??, and 15??C in laboratory experiments. At 11??C, 5 fish ranging from 11 to 19 cm in length had a mean Ucrit of 48.24 cm/s or 3.22 body lengths per second (BL/s). Also at 11??C , 6 fish from 32 to 42 cm had a mean Ucrit of 73.99 cm/s or 2.05 BL/s. At 15??C, 5 fish from 14 to 23 cm had a mean Ucrit of 54.66 cm...
