Vegetation Monitoring
The National Park Service (NPS) at Lake Mead National Recreation Area (LAME) entered into a cooperative agreement with the University of Nevada, Las Vegas (UNLV) to accomplish vegetation monitoring and management activities. This report summarizes activities that took place by UNLV under this task agreement between October 1, 2005, and September 30, 2006. The activities included:
- Weed Sentry mapping and treating incipient populations of exotic invasive plants throughout Clark County, including along shorelines of Lakes Mead and Mohave;
- Monitoring of targeted rare native plant species;
- Sahara mustard research; and
- Providing technical assistance upon request to the NPS vegetation manager.

Feeding Habitats Of Spring-Migrating Blackbirds In East-Central South Dakota, Richard S. Sawin, George M. Linz, William J. Bleier, H. Jeffrey Homan
Feeding Habitats Of Spring-Migrating Blackbirds In East-Central South Dakota, Richard S. Sawin, George M. Linz, William J. Bleier, H. Jeffrey Homan
The Prairie Naturalist
Between March 27 and April 21, 1998, we monitored blackbird (Icteridae) activity and habitat selection at a migratory staging area in east-central South Dakota. We used fixed-area observation points located within 20 l-km2 circular plots centered on four wetland basins that were used as night roosts. Each roost was surveyed four times, with the surveys spread evenly throughout the blackbird migration. We recorded the number of blackbird flocks, flock size and composition, habitat used, and behavior (e.g., loafing and feeding). Fifty percent (n = 242) of the 482 flocks recorded in the quadrats was observed loafing in trees …

Population Biology Of Pumpkinseed In Enemy Swim Lake, South Dakota, Eric J. Weimer, Michael L. Brown
The Prairie Naturalist
Little information is available regarding the biology and population characteristics of pumpkinseed (Lepomis gibbosus), especially in South Dakota, a state at the western edge of the species native range. South Dakota Department of Game, Fish and Parks summer trap net survey data, collected 1998 to 2003, suggests the Enemy Swim Lake population has low abundance (0.4-2.9 per trap net night) and moderately high size structure (proportional stock density [PSD] ranges between 71 and 91). To further examine the biological characteristics of the Enemy Swim Lake population, pumpkinseed was collected from Indian Bay with trap nets during May 2003. …

Reproductive Development In The Sicklefin Chub In The Missouri And Lower Yellowstone Rivers, Douglas J. Dieterman, Eric Roberts, Patrick J. Braaten, David L. Galat
The Prairie Naturalist
We describe aspects of sicklefin chub (Macrhybopsis meeki) reproductive development from three study areas encompassing greater than 2,700 km of the Missouri and Lower Yellowstone rivers. The sicklefin chub was collected between late July and early October in 1996 and 1997. A total of 193 sicklefin chub was collected and examined for reproductive characteristics. Twenty-nine sicklefin chub were found to be reproductively mature females. Some sicklefin chub matured at age 2, but most matured at age 3 and all matured by age 4. Females first became mature at 70 to 79 mm total length (TL) in the Upper …

Invasive Species Definition Clarification And Guidance, Invasive Species Advisory Committee
National Invasive Species Council
Summary
Invasive species are those that are not native to the ecosystem under consideration and that cause or are likely to cause economic or environmental harm or harm to human, animal, or plant health. Plant and animal species under domestication or cultivation and under human control are not invasive species. Furthermore for policy purposes, to be considered invasive, the negative impacts caused by a non-native species will be deemed to outweigh the beneficial effects it provides. Finally, a non-native species might be considered invasive in one region but not in another. Whether or not a species is considered an invasive …

First Record Of The Spurge Hawkmoth As A Pollen Vector For The Western Prairie Fringed Orchid [Notes], Carla R. Jordan, Gerald M. Fauske, Mrion O. Harris, Darla Lenz
The Prairie Naturalist
Identification of pollen vectors is one step in refining management plans for a threatened plant such as the western prairie fringed orchid (Platanthera praeclara Sheviak and Bowles). Pollen vector bionomics, phenology, and ethology must be understood to assess this moth and other potential pollinators relative to orchid reproductive success. Also, the ability of spurge hawkmoth (Lepidoptera: Sphingidae), a recently introduced species, to act as a pollen vector for an obligate prairie plant, the western prairie fringed orchid, in theoretical terms, provides evidence which contradicts long held tenets of one-to-one correspondence between orchids and their pollinators. Further research might shed …
