Publikováno v: Bulletin of environmental contamination and toxicology. 104(5)

Total mercury (THg) and selenium (TSe) levels were measured in stomach contents (SC) and twelve tissues of cutthroat trout (Oncorhynchus clarkii) occurring in three high-elevation lakes of Colorado, USA, inhabiting watersheds absent past and current

Autor: Scott J. Herrmann, Lynn M. Herrmann-Hoesing, James S. Carsella, Brian Vanden Heuvel, Del Wayne R. Nimmo, Lisa K. Helland, James E. Sublette

Publikováno v: Western North American Naturalist. 76:186-252

The primary purpose of this study was to assess the chironomid species diversity of a high-gradient sandy-bottom watershed along the Colorado Front Range. Adult male Chironomidae were collected concurrently in 2007 and 2008 from 14 sites in the Fount

Variable Uptake of Selenium: Exposing Bryophytes in Situ to a Se-Gradient Watershed

Autor: Igor Melnykov, Del Wayne R. Nimmo, James S. Carsella, Scott J. Herrmann

Publikováno v: Western North American Naturalist. 80:215

We investigated the uptake of selenium (Se) at 14 sites in a Se-rich watershed, using an aquatic bryophyte (Hygrohypnum ochraceum). We expressed uptake using the symbol Kd to underscore the relationships between Se in water and Se in plants as “par

New Altitudinal Records for, and Ecomorphic Variation in, Two Freshwater Sponges (Porifera: Spongillidae: Spongilla lacustris and Ephydatia muelleri) from a Colorado, USA, Alpine Lake

Autor: Del Wayne R. Nimmo, Scott J. Herrmann, Lynn M. Herrmann-Hoesing

Publikováno v: Western North American Naturalist. 79:347

The primary objective of this article is to report the co-occurrence of Spongilla lacustris (Linnaeus 1759) and Ephydatia muelleri (Lieberkuhn 1855) in an alpine Colorado lake whose altitude of 3580 m represents new elevation maximums for these spong

Range extensions for three new invasive species in Pueblo Reservoir, Colorado, USA: water flea Daphnia lumholtzi (G. O. Sars, 1885), calanoid copepod Eurytemora affinis (Poppe, 1880), and freshwater bryozoan Lophopodella carteri (Hyatt, 1865)

Autor: John R. Beaver, DelWayne R. Nimmo, Scott J. Herrmann, Candace E. Walker

Publikováno v: BioInvasions Records. 2:207-214

This is the first report of the occurrence of three invasive species in Colorado, USA: the water flea, Daphnia lumholtzi (G. O. Sars, 1885); calanoid copepod, Eurytemora affinis (Poppe, 1880); and a freshwater bryozoan, Lophopodella carteri (Hyatt, 1

Bioaccumulation of Selenium by the Bryophyte Hygrohypnum ochraceum in the Fountain Creek Watershed, Colorado

Autor: J. A. Turner, D. W. Lehmpuhl, James S. Carsella, D. R. Nimmo, Scott J. Herrmann

Publikováno v: Environmental Management. 50:1111-1124

Aquatic bryophytes, Hygrohypnum ochraceum, were deployed “in situ” at 14 sites in the Fountain Creek Watershed, spring and fall, 2007 to study selenium (Se) accumulation. Dissolved, total, and pore (sediment derived) water samples were collected
