The Marsh Beetles (Coleoptera: Scirtidae) Of Pine Hollow And The Uw-Milwaukee Field Station, Daniel K. Young

Field Station Bulletins

Four species of marsh beetles were collected from Pine Hollow during the 1987 field season. Of these, Prionocyphon discoideus (Say) represents a new state record. In addition, specimens of an undescribed Cyphon were also recovered. During the same period, 12 scirtid species were taken at the UW-Milwaukee Field Station. Of these, new state records are reported for five species of Cyphon: fuscescens Klausnitzer, neovariabilis Klausnitzer, orohreatus KLausnitzer, perplexus Blatchley, and ruficollis (Say). Only two species, Flavohelodes thoracica (Guerin-Meneville) and Cyphon obscurus (Guerin-Meneville), were recovered from both sites. Observational notes are included for each of the species found at the two …

Glossy Buckthorn (Rhamnus Frangula), A Threat To The Vegetation Of The Cedarburg Bog, James A. Reinartz, Joanne Kline

Field Station Bulletins

Glossy buckthorn (Rhamnus frangula) is a shrub or small tree which is a native of Eurasia, introduced to North America about the mid-nineteenth century. Escaped from cultivation, Rhamnus frangula is rapidly becoming a serious pest in certain kinds of wetland habitats and has been in the Cedarburg Bog for at least the last thirty years. Glossy buckthorn is most dense in the string bog, the most unique vegetation type in the Bog. Since 1968, the string bog population of Rhamnus frangula has been growing logarithmically at a rate which doubles the population size in less than 4 years. Individual shoots …

Status Of Alien Plant Species In Eight State Naturalareas In Eastern Wisconsin, Lawrence A. Leitner

Field Station Bulletins

An annotated list of the non-native plant species found in eight eastern Wisconsin natural areas and their relative abundances in 1988 is presented. Except for European buckthorn, aliens were scattered and at low densities, several found mainly along trails. The most seriously invaded sites were Sanders Park and Muskego Park, areas with numerous hiking trails and relatively open, oak-dominated canopies.

B819: The Spruce Budworm Outbreak In Maine In The 1970'S–Assessment And Directions For The Future, Lloyd C. Irland, John B. Dimond, Judy L. Stone, Jonathan Falk, Ellen Baum

Bulletins

This report was initiated by the Maine Forest Service (MFS) in response to concerns that a serious effort was needed to capture the experiences and lessons learned during the 1970-85 spruce budworm outbreak in Maine. The report synthesizes the observations and experiences of land managers, as well as the principal results of recent scientific research on spruce budworm in Maine. This report briefly reviews budworm population dynamics and interactions with the forest, then describes the budworm's impacts in detail. It then reviews the three principal responses: survey and detection; spraying; and silviculture and salvage. It then offers an overview of …

Long-Term Population Trends In Songbirds: Evidence From A General Netting Program, Charles M. Weise

Field Station Bulletins

A one-day-a-week general bird-netting operation has been conducted each autumn since 1965 at the UWM Field Station. Overall results for 23 years are presented, on a species by species basis. The 101 species captured were divided into three groups for a linear regression test for long-term population trends. Permanent residents showed no change over the 23 years. Short distance migrants exhibited a slight but not statistically significant decline. Long-distance migrants, on the other hand, exhibited a statistically significant decline, lending support to other studies which have reported population declines in North American songbirds that spend the winter in the tropics.

Long-Term Population Fluctuations Of Small Mammals At The Uwm Field Station, James W. Popp, Paul E. Matthiae, Charles M. Weise, James A. Reinartz

Field Station Bulletins

Population sizes of four small mammals, Peromyscus leucopus, Microtus pennsylvanicus, Blarina brevicauda, and Sorex cinereus, were monitored for over twenty years at the UWM Field Station. P. leucopus had moderate fluctuations in size, but showed no evidence of cyclic or regular fluctuations. M. pennsylvanicus exhibited dramatic fluctuations with cycles of 3-5 years. Neither shrew species appeared to have cyclic fluctuations. The population sizes of the two shrew species were positively correlated with each other. No other significant correlations were found between species. Population sizes were probably influenced by a number of factors including predation, competition and weather.

Additions To The Fungi Of The Uwm Field Station, Alan D. Parker

Field Station Bulletins

A preliminary checklist totaling 147 species of fungi identified from the Field Station was published recently (Parker, 1987). Extensive collecting in the beech-maple hardwoods and one trip into the cedar-tamarack swamp during July-October 1987 have provided records of an additional 54 species. Among the fungi identified during 1987 are the following noteworthy taxa: Thuemenella cubispora (Ellis & Holw.) Boedjn - Ascomycetes, Hypocreales

Control Of Herbaceous Competitors In Progeny Tests Using Container-Grown Seedlings, Jimmie L. Yeiser, J. W. Boyd, D. J. Reed

Journal of the Arkansas Academy of Science

Container-grown and May-planted seedlings of loblolly and shortleaf pines were treated with herbicides for control of herbaceous competitors. Weed control and seedling growth were evaluated. Competitor control was good for all treatments. Survival and growth of pines differed by species and herbicide treatment. The best treatment for both species included covering seedlings and spraying competitors with glyphosate. Both species showed decreased survival and growth when treated with medium and high rates of hexazinone + sulfometuron methyl.

Survival And Growth Two Years After Control Of Herbaceous Competitors In Newly Planted Seedlings Of Loblolly Pine, Jimmie L. Yeiser, J. W. Boyd

Journal of the Arkansas Academy of Science

Early or late over-the-top applications of herbicides were used to control herbaceous competition in machine planted loblolly pine (Pinus taeda L) seedlings at two locations in a pasture near Alleene and hand planted seedlings on a bedded site near Fouke. Sites were selected for diverse competitors. None of the treatments controlled weeds for the entire growing season. Only glyphosate + sulfometuron methyl produced seedling survival and growth below the check plots. The best over-the-top treatments were sulfometuron methyl alone or sulfometuron methyl + hexazinone.

Douglas-Fir Beetle (Dendroctonus Pseudotsugae Hopkins, Coleoptera : Scolytidae) Brood Production On Douglas-Fir Defoliated By Western Spruce Budworm (Choristoneura Occidentalis Freeman, Lepidoptera : Tortricidae) In Logan Canyon, Utah, S E. Fredricks, M J. Jenkins

The Bark Beetles, Fuels, and Fire Bibliography

Douglas-fir beetle brood production was studied on Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) trees defoliated by the western spruce budworm between 1983 and 1985. Tallies were made of the number of attacks, total length and number of egg galleries, number of eggs deposited, number of larval tunnels, number of pupal chambers, and number of emerging beetles (per female and per unit area). Data analysis showed no significant differences among the three years studied. The number of emerging beetles per female parent was 0.59, and emergence per 90 cm2 was 2.32 beetles. Egg, larval, and pupal survivals were 47.5%, 30.0%, and 15.5%, …

Lodgepole Pine Vigor, Regeneration, And Infestation By Mountain Pine Beetle Following Partial Cutting On The Shoshone National Forest, Wyoming, Gene D. Amman, Gene D. Lessard, Lynn A. Rasmussen, Curtis G. O'Neil

The Bark Beetles, Fuels, and Fire Bibliography

Lodgepole pine stands were thinned in the Shoshone National Forest of northwestern Wyoming in 1979 and 1980 using different forms of partial cutting. Average losses of trees 5 inches diameter at breast height and larger to mountain pine beetles during the 5 years following thinning ranged from less than 1 percent in spaced thinnings to 7.4 percent in the 12-inch diameter limit cut, compared to 26.5 percent in check stands. Residual trees increased radial growth significantly, but change in growth efficiency is slow. Regeneration 5 years after thinning ranged between 1,160 and 3,560 seedlings per acre, with pine being favored …

Host Selection In Subterranean Termites: Factors Affecting Choice (Isoptera: Rhinotermitidae), Deborah Ann Waller

Biological Sciences Faculty Publications

The effects of block size and species on preference were examined for the subterranean termite Reticulitermes sp. (Rhinotermitidae) in choice and no-choice tests. Termites significantly preferred Douglas fir over Ponderosa pine and red oak, irrespective of block size. The less-preferred woods were eaten in large amounts in no-choice tests, and all three woods appeared to be favorable for the termites and their gut protozoans. In single species tests, termites ate significantly more from larger blocks of Douglas fir, but ate similar amounts from large and small blocks of Ponderosa Pine and red oak. These results suggest that several factors can …
