Community-Owned Forests: Possibilities, Experiences, and Lessons Learned (June 16-19)
Community-owned forests may be the answer for some U.S. communities now confronting unanticipated and unwanted large scale land use changes – changes that could irrevocably change their local landscapes and quality of life. Across the country, millions of acres of private forest lands are being put up for sale as the forest products companies who own them find other, cheaper sources of supply. If, as is likely, purchasers divide and convert the forests to residential or other development uses, nearby communities face losing the critical economic, environmental, recreational, social, cultural, and aesthetic values and benefits those forests have traditionally provided. …
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
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
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
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
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 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 …

An Additional Record Of The Ornate Box Turtle From Western South Dakota, Steven G. Platt, Jennifer I. Stover, Edward J. Stover Iii
The Prairie Naturalist
On June 11, 2003, one of us (EJS) found an ornate box turtle crossing BIA Highway 2, approximately 7.2 km north of Sharps Comer on the Pine Ridge Indian Reservation in Shannon County, South Dakota. The air temperature at the time of collection was approximately 30°C and the substrate was moist from light rain the previous day. The turtle was an adult female with a straight-line carapace length of 118 mm. Other straight-line measurements were: maximum carapace width = 100 mm; plastron length = 122 mm; maximum plastron width = 82 mm; and maximum shell depth = 64 mm. We …
Fisheries Occasional Paper No. 19 - Management Of Western Rock Lobster Fishery - Proposed Resource Sustainability Management Package For The Northern Zones (A And B), Department Of Fisheries Western Australia
Fisheries Occasional Paper No. 19 - Management Of Western Rock Lobster Fishery - Proposed Resource Sustainability Management Package For The Northern Zones (A And B), Department Of Fisheries Western Australia
Fisheries Occasional Publications
The proposed effort reduction management package presented in this paper was developed in close co-operation with rock lobster industry to address the short-term sustainability concerns regarding the level of breeding stock in the northern region.
The management package does not address the serious long-term sustainability or socio-economic issues (e.g. cost pressures and related fleet capacity) facing the industry. If the fishery stays with input controls there will need to be regular reviews of the level of exploitation and its impact on the breeding stock. If exploitation increases and the breeding stock continues to decline additional fishing effort reductions in the …

Fisheries Occasional Paper No. 20 - Management Of Western Rock Lobster Fishery - Advice To Stakeholders - Assessment Of Southern Zone Resource Sustainability Options, Department Of Fisheries, Western Australia
Fisheries Occasional Publications
The management options presented in this paper have been developed in close cooperation with the rock lobster industry to address the short-term sustainability and economic concerns regarding the level of exploitation and its impact on the breeding stock in the southern region. The main focus in the short-term is to consider options that reduce fishing effort during periods that may be economically inefficient to fish and at the same time reduce the level of exploitation.
The management package does not address the serious long-term sustainability or socioeconomic issues (e.g. cost pressures and related fleet capacity) facing the industry. If the …

Observed Omnivory In The Herbivorous Blue Tilapia (Oreochromis Aureus), Stephen M. Oliveira Jr.
UNLV Theses, Dissertations, Professional Papers, and Capstones
Gila seminuda, a native endangered species, and Oreochromis aureus, a nonnative invasive species, share the same habitat in the form of the Reid Gardner Power Plant intake ponds. The purpose of this study is to characterize the feeding habits of Oreochromis aureus within the Reid Gardner Power Plant intake ponds and address the potential predation habits of Oreochromis aureus. Stomach contents of O. aureus were identified and analyzed using chi-square and log-likelihood ratio techniques, with respect to mass, length, girth, gender, or spatial distribution of samples. Results showed omnivorous behavior with a 7.00% predatory/prey relationship, and no difference of feeding …

Natural Loggers: Leaf Cutter Ants As Pests In Northwestern Ecuador, Aaron Honig
Natural Loggers: Leaf Cutter Ants As Pests In Northwestern Ecuador, Aaron Honig
Independent Study Project (ISP) Collection
The biological world is under attack. All across the world in every continent and sub-continent biological diversity is rapidly decreasing (Wilson, 1999). As the human population continues to exponentially increase, especially in Third World countries where biological diversity reaches its peak, countless diverse biological habitats are threatened by accelerating human consumption and the growing needs of growing human populations. In Ecuador, only 1% of the original tropical forest remains, as a result of the accelerating need of viable agricultural tracts for Ecuador’s relatively poor farmers, as well as the unsustainable harvest of valuable hardwood tree species endemic to Ecuador’s primary …

Fisheries Research Report No. 149 - The Western Rock Lobster Fishery 2001/2002 To 2002/2003, C F. Chubb, E H. Barker
Fisheries Research Reports
Season 2001/2002 produced 8,983 tonnes, a far cry from last season’s catch of 11,300 t. The sharp decline in catch was most likely the result of unfavourable environmental conditions throughout much of the season. The catches by the three zones were 1,651 tonnes in zone A, 2,800 tonnes in zone B and 4,532 tonnes in zone C. The sharp decline in total catch on the previous season was also reflected in declining catches in the three zones. Nominal effort also declined slightly from 10.487 million pot lifts in 2000/2001 to 10.367 million pot lifts in 2001/2002. Following the very low …

Fisheries Research Contract Report No. 12 - Mitigation Of The Negative Impacts On Biodiversity And Fisheries Values Of The Refurbishment Of Waroona Dam, South-Western Australia (Final Report For The Water Corporation Of Western Australia), Brett Molony, Stephen Beatty, Chris Bird, Vinh Nguyen
Fisheries Research Contract Reports
In addition to the supply of water for agriculture, irrigation dams of south-western Australia are important systems for recreational activities, including fishing (Molony & Bird 2002, Molony et al. 2002a). Lake Navarino (the reservoir created by Waroona Dam, figures 1 and 2, approx. 115° 55 E 32° 51 S) is the first major public access reservoir south of the Perth Metropolitan Area and is an important component of the Recreational Marron (Cherax tenuimanus') Fishery (RMF) (Molony 2001a, 2002a, 2003a, Molony & Bird 2002, Beatty et al. 2003a). Further, it is the most northerly irrigation dam that is regularly stocked with …
The Quintessential Companion For North American Birders: Review Of The Birdwatcher's Companion To North American Birdlife By Christopher W. Leahy, Lawrence Igl
The Prairie Naturalist
The Birdwatcher's Companion was revised in 2004 under a new title, The Birdwatcher's Companion to North American Birdlire, and by a new publisher, Princeton University Press. This substantial work builds on Leahy's previous edition published in 1982. Hailed by the publisher as the quintessential, alphabetically arranged guide to North American birdlife, the new edition of The Birdwatcher's Companion is over 100 pages longer than the first edition, but, overall, the style and format have not changed much between the two editions. The Companion begins with a brief chapter in which the author describes how to use the book, how it …
Factors Influencing Persistence Of White-Footed Mice, Brock R. Mcmillan, Glennis A. Kaufman, Donald W. Kaufman
Factors Influencing Persistence Of White-Footed Mice, Brock R. Mcmillan, Glennis A. Kaufman, Donald W. Kaufman
The Prairie Naturalist
We examined factors that potentially influenced persistence of the white-footed mouse (Peromyscus leucopus) during 1981 to 1988 at Konza Prairie Biological Station, Kansas. We predicted that both abiotic (e.g., precipitation and temperature) and biotic (e.g., availability of food and density of conspecifics) factors would influence persisten~e of individuals at the study site. Persistence of individual white-footed mice on the study site differed among years and seasons. White-footed mice that were first captured in summer or in autumn persisted longer than those first captured in spring. Young females (less than 20 g) had greater persistence than young males, whereas …
Lack Of Brown-Headed Cowbird Nest Parasitism In A Short Grass Region, Stephen L. Winter, Jack F. Cully Jr.
Lack Of Brown-Headed Cowbird Nest Parasitism In A Short Grass Region, Stephen L. Winter, Jack F. Cully Jr.
The Prairie Naturalist
While conducting field work in Morton County, southwestern Kansas and Baca County, southeastern Colorado, during the period 27 May to 2 July 1997, we found 36 nests of seven bird species. Nests were not searched for systematically, but were found coincidentally as data were collected along transects during research investigating the breeding bird and plant communities of black-tailed prairie dog (Cynomys ludovicianus) colonies and noncolonized shortgrass prairie (Winter 1999).
Low densities of the brown-headed cowbird in our study region, which is characterized by a semi-arid climate, might be a consequence of host populations that exhibit extreme temporal and …
Comparison Of Microclimate At Grassland Bird Nests With Different Substrates, Kimberly M. Suedkamp Wells, Samuel D. Fuhlendore
Comparison Of Microclimate At Grassland Bird Nests With Different Substrates, Kimberly M. Suedkamp Wells, Samuel D. Fuhlendore
The Prairie Naturalist
We compared the effects of two different nest placement strategies (shrubs vs. bunchgrasses) on microclimate conditions for grasshopper sparrow (Ammodramus savannarum) and lark sparrow (Chondestes grammacus) in Oklahoma. We predicted that the intensity and duration of extreme temperatures (greater than 39° C) and their variability would be reduced at shrub nests compared to bunchgrass nests. A verage maximum temperatures were similar at nests of grasshopper sparrow and lark sparrow, but confidence intervals were more variable and included biologically detrimental temperatures at grasshopper sparrow nests compared to lark sparrow nests. The proportion of time greater than 39° …
The Sooner State Bird Atlas: Review Of Oklahoma Breeding Bird Atlas, Dan L. Reinking, Editor, Timothy J. O'Connell
The Sooner State Bird Atlas: Review Of Oklahoma Breeding Bird Atlas, Dan L. Reinking, Editor, Timothy J. O'Connell
The Prairie Naturalist
In Oklahoma, forest meets prairie, prairie meets mesa, and throughout, our native ecosystems are shaped by human land use. Across this shifting mosaic of habitats, animals find food, raise young, and disperse to find other members of their species. Management for these species is best informed when it springs from a common baseline of knowledge about distributions across the entire management area. For birds, that baseline can be effectively established with a breeding bird atlas. ... In sum, the Oklahoma Breeding Bird Atlas presents timely information on a fascinating statewide avifauna in a clear and attractive package. The text is …
