Summary
Description
In June 1992, we collected 52 plasma samples from nestling redwinged blackbirds Age latus phoeniceus, house sparrows Passer domesticus, and brownheaded cowbirds Molothrus ater at 5 study sites near the town of Ada in northwestern Minnesota. Three sites were adjacent to sugar beet fields that were likely to be treated with Lorsban an organophosphate insecticide for control of sugar beet root maggots Tetanops myopaeformfs, and 2 sites were distant from fields likely to be treated reference sites, Application of Lorsban in fields surrounding study plots was monitored through contact with landowners and direct observations. Cholinesterase ChD activity levels total cholinesterase TChD, acetylcholinesterase AChE, and butyrylcholinesteraseBChE in nestling plasma were measured and tested TChE and AChE for reactivation in the presence of 2PAM, an indication of exposure to organophosphate insecticides. In addition, 11 nestlings were euthanized and in these samples we measured brain ChE activity and reactivation, and we analyzed gastrointestinal tracts and carcass washes for Lorsban residues. Total ChE and BChE activity were lowest in similaraged nestlings at sites adjacent to treated beet fields TChE, t 2.51, d. f. 21, P 0.033; BChE, t 2.56, d.f. 21, P 0.043. Nestlings from sites that were near fields where Lorsban was applied were more likely to exhibit plasma AChE reactivation than nestlings from reference sites where OP or carbamate insecticide application was improbable Xsquare 3.805, df. 1, Pz 0.05. The magnitude of plasma ChE reactivation was highest within 13 days of insecticide application, although significant reactivation was measured up to 11 days after application of Lorsban. Plasma AChE reactivation appeared to be a more sensitive indicator of exposure to ChEinhibiting insecticides than absolute TChE or BChE activity levels. The occurrence of Lorsban residue in gastrointestinal tracts and carcass washes suggested that nestlings were exposed to insecticides through prey delivery andor physical contact with adults.

This report was prepared as one facet of the current research project entitled Assessment of Impacts to Fish and Wildlife from Pesticide Use on the Western Oregon Refuge Complex. This research project was designed to investigate pesticide impacts on aquatic communities on refuge lands. The study is scheduled to be completed in 4 phases, including; 1 collection of background information, 2 collection and analysis of water samples, 3 performance of insitu fish bioassay, and 4 collection and analysis of blood hormone levels in common carp and western pond turtles. This report is a summary of background information gathered as the first phase of the research project.

Description
The purpose of this report is to analyze the water budget and water quality for West Knox Pond for the May through September period of 2002 and 2003. The determination of the water budget will allow us to calculate nutrient loads and evaluate downstream water quality impacts, as well as estimate water lost through evapotranspiration ET. Evapotranspiration rates estimated using the water balance approach will allow a comparative assessment of alternative modeled estimates of ET using readily available meteorological data.

New distribution record for the Indiana cave crayfish, Orconectes inermis inermis cope, from the Patoka River drainage
Published By US Fish and Wildlife Service, Department of the Interior
Issued mehr als 9 Jahre ago
Summary
Description
Two specimens of the Indiana cave crayfish, Orconectes Orconectes inermis inermis Cope, were collected from a cave referred to as Audreys Cave on May 21, 2001 from the Patoka River drainage. This is the first record of the Indiana cave crayfish from the Patoka River drainage. The site locality is an unnamed tributary, Orange County, upstream of the County Road 475 E bridge, along a path into Hoosier National Forest, Stumpers Creek Township, latitude 38 29.38 longitude 86 21.79. The specimens were also collected with three specimens of the karst crayfish, Cambarus Erebicambarus tenebrosus Hay. Karst connections with the Lost River cave system may be the dispersal mechanism that enabled colonization into the Patoka River watershed.
