Influence Of Biocontrol Insects On Canada Thistle: Seed Production, Germinability, And Viability, Gary E. Larson, Tim A. Wittig, Kenneth F. Higgins, Brent Turnipseed, Dawn M. Gardner

The Prairie Naturalist

We conducted surveys of thistle-feeding insects on Canada thistle [Cirsium arvense (L.) Scop.] during the 2000 and 2001 growing seasons at Lacreek National Wildlife Refuge (LNWR), South Dakota, and analyzed their impact on thistle seed production, germination, and viability. Insects included Canada thistle stem weevil [Hadroplontus litura, formerly Ceurtorhynchus lilura, (Coleoptera: Curculionidae)], introduced at LNWR as a biocontrol agent, plus two seed head parasites, the thistle head weevil [Rhinocyllus conicus (Coleoptera: Curculionidae)] and the seed head fly [Terellia ruficauda (Diptera: Tephritidae)]. Infestation by these insects caused no significant reduction in per-head seed yield, with means ranging from 82.5 seeds per …

Christmas Bird Counts For North Dakota 2004, Robert N. Randall

The Prairie Naturalist

Christmas Bird Counts were made in 21 areas in North Dakota again in the year 2004. During the year a new count site was established in Pembina County and registered with the Audubon Society but an actual count was not made in the area this year. The location of the all areas in which counts were actually made is shown in Fig. 1. A relatively mild fall season leading up to the count period left much more open water than normal. Weather conditions during the count period varied widely with some areas reporting temperatures in the 40's and 50's of, …

Biological Notes On Ground-Nesting Digger Wasps From Western Nebraska, Robert W. Matthews, Janice R. Matthews

The Prairie Naturalist

Nine species of sphecid wasps nesting in sparsely vegetated sandy soils near Ogallala, Keith County, Nebraska were studied during June 2003. The first records of the nest and prey of Cerceris clypeata gnarina Banks and Tachysphex williamsi R. Bohart are presented. Two species of weevils, Baris striata Say and B. subsimilis Casey, were prey of C. clypeata gnarina, with 12 to 22 individuals stocked per cell. Because B. subsimilis is a biological control agent for thistle, this finding is a caution to researchers not to ignore the potential impact of predatory wasps on the community. The single nest of T …

Grazing Intensity Effects On Northern Plains Mixed-Grass Prairie, Wendi M. Rogers, Donald R. Kirby, Paul E. Nyren, Bob D. Patton, Edward S. Dekeyser

The Prairie Naturalist

We evaluated the effects of long-term (1988 to 2000) grazing on northern mixed-grass prairie at tI.e Central Grasslands Research Extension Center in south-central North Dakota. We did not detect a difference in herbaceous basal cover between grazing intensities following 12 consecutive years of season-long moderate (50% removal of annual above-ground standing crop) and heavy (80% removal of annual above-ground standing crop) grazing. However, both moderate and heavy grazing intensities reduced above-ground herbaceous standing crop, total root biomass, and soil organic carbon. Moderate grazing intensity maintained a greater amount of deep (10 to 20 cm) and total root biomass relative to …

Fisheries Occasional Publication No.21 - Allocation Of The Western Rock Lobster Resource Between User Groups, Department Of Fisheries Western Australia

Fisheries Occasional Publications

In this submission to IFAAC, the Department will outline what it believes are the most practical and cost effective ways of managing a system of allocation amongst the commercial, customary and recreational sectors. This recommendation recognises that cost efficiencies and outcomes will be greatly affected by the type of allocation model that is chosen. Consequently the Department recommends that the allocation system should be based on a single allocation to each sector that is available over the entire fishery.

The Department does not recommend having any finer scale zoning of the allocations, or the creation of exclusive recreational fishing areas. …

Mammals Of Fort Leavenworth, Kansas: A 60-Year Followup To Brumwell (1951), Clay R. Davis, Frederick B. Stangl Jr., Lynn W. Robbins

The Prairie Naturalist

More than 60 years have elapsed since Brumwell's (1951) comprehensive assessment during 193911940 of resident terrestrial vertebrates from Fort Leavenworth Military Rooervation in northeastern Kansas. Subsequent studies have been accomplished for the amphibians, reptiles, and birds. Our study is the first to assess intervening changes in the mammalian composition of this diverse local fauna. Notable observations include: the decline or extirpation of the black-tailed jackrabbit (Lepus californicus), Franklin's ground squirrel (Spermophilus franklinii), muskrat (Ondatra zibethicus), long-tailed weasel (Mustela frenata) and eastern spotted skunk (Spilogale putorius); the return or recovery of locally extirpated gray fox (Urocyon cinereoargenteus), puma (Puma concolor), and …

The Ten Mile River Study

Watershed Access Lab Projects

In the past year, North Attleboro High Schools’ environmental science class has been conducting an intense study of the Ten Mile River. The focus of our study is to find out detailed information regarding the biological, physical, and chemical state of the river.

The Ten Mile River is the main river within North Attleboro. It runs down to Narragansett Bay and flows through many other local towns. The river begins at Cargill Pond in Plainville and flows 23 miles through North Attleboro, Attleboro, Plainville, and Seekonk before going into Rhode Island.

We studied two sites along the river within Bristol …

Long Pond Replication Study

Watershed Access Lab Projects

Long Pond, due to changes in demographics over the past 20 years, is experiencing environmental stress from two sources. One is the documented presence of Eurasian Milfoil and the other is the increased population density with small lot size in areas immediately adjacent to the pond. It is believed that effluent from overtaxed septic systems is moving into the pond via subsurface flow. ARHS students completed a study of water quality in 2001. At that time they found fecal coliform counts of 215 colonies/100 ml at Clark Shores. The Lakeville Conservation Commission wanted to know whether conditions have improved. This …

The Loon Pond Experience

Watershed Access Lab Projects

Since a previous study dealt with the water quality of Loon Pond, this year’s study focused on the possible presence of invasive aquatic weeds. Lakeville, like other towns in Massachusetts, is having a difficult battle with Eurasian Milfoil. The Lakeville Conservation Commission wanted to know whether the weed had also invaded Loon Pond. The study found many indigenous species of aquatic weeds. There was no evidence of Eurasian Milfoil. Water quality was within acceptable limits for pH, DO, temperature, reactive phosphorus and nitrogen as nitrate. Any increases in monthly concentrations of RP and NO₃ were explained by weather and …

Long Pond Five Site Study

Watershed Access Lab Projects

Long Pond, due to changes in demographics over the past 20 years, is experiencing environmental stress from two sources. One is the documented presence of Eurasian Milfoil and the other is the increased population density with small lot size in areas immediately adjacent to the pond. Lakeville Conservation Commission has tested and found fecal coliform bacteria in private wells of residents on Long Pond. In 2001, ARHS students found fecal coliforms the water of the pond itself. The Commission wanted to know whether the presence of fecal coliforms and concentrations of reactive phosphorus are weather dependent. Sampling for fecal coliforms …

How Polluted Is West Meadow Brook?

Watershed Access Lab Projects

This was a study of two sites along West Meadow Brook, located on the campus of Brockton High School. The river has been monitored by groups at BHS over the past four years and is known to be polluted. The purpose of the study completed this year was to continue monitoring the quality of the river and how it is being affected by its surroundings. The river is flanked by playing fields, including Marciano Stadium and Campanelli Stadium, on one side, and Brockton High’s main campus and parking lots on the other side. The maintenance of these playing fields, as …

Mussel Mania

Watershed Access Lab Projects

Long Pond, because of changes in demographics over the past 20 years, is experiencing environmental stress from the presence of Eurasian Milfoil. Two herbicides, Sonar and Diquat, were applied to water in the residential area of Long Pond known as Parkhurst in order to eradicate the milfoil. Shortly after this application a report was made of dead mussels floating on the north side of Assawampset Pond. Long Pond and Assawampset Pond are connected via Snake River. There is some speculation that there is also a connection via a culvert between Parkhurst and Assawampset Pond. The Lakeville Conservation Commission wanted to …
