Notes On The Milliped Pleuroloma Flavipes (Polydesmida: Xystodesmidae) In Wisconsin, Dreux J. Watermolen, G Andrew Larsen
Notes On The Milliped Pleuroloma Flavipes (Polydesmida: Xystodesmidae) In Wisconsin, Dreux J. Watermolen, G Andrew Larsen
Field Station Bulletins
The milliped Pleuroloma flavipes Rafinesque 1820 is one of the more widespread and better known North American millipeds. During the course of recent studies in Wisconsin, we have had opportunities to examine museum specimens and make field observations of this species. In this note, we report new locality records, discuss observations of mass aggregations, describe a color variation, and illustrate an individual with developmental abnormalities.
The Centipede Lithobius Celer (Chilopoda: Lithobiidae) In Wisconsin, Dreux J. Watermolen
The Centipede Lithobius Celer (Chilopoda: Lithobiidae) In Wisconsin, Dreux J. Watermolen
Field Station Bulletins
The centipede Lithobius celer Bollman 1888 has been reported from Wisconsin only one time. Chamberlin (1911) provisionally referred specimens collected from unspecified Wisconsin and Michigan localities to this species, with considerable doubt since neither was a ''fully-grown male/' Subsequent investigators (e.g., Matthews 1935, Crabill 1958) did not report L. celer from the state. While examining specimens collected as part of an on-going prairie ecology study, I discovered a L. celer specimen from southern Wisconsin. The specimen was collected in a pitfall trap at Hawkhill Prairie, Dane County (T9N, R8E, Sec. 5) on 21 August 1986 by A. Lisken.
Comparison Of Wisconsin Terrestrial Isopods And Their Life Cycle Traits, Joan Jass, Barbara Klausmeier
Comparison Of Wisconsin Terrestrial Isopods And Their Life Cycle Traits, Joan Jass, Barbara Klausmeier
Field Station Bulletins
Seasonal reproductive patterns for the 11 terrestrial isopod species found in Wisconsin are presented. The pattern of the most widespread species, Trachelipus rathkei, is examined hi detail through a series of paired north/south samplings which reveal a seasonal lag in the percent of females which were gravid in populations from the northern part of the state. A difference in sex ratio between north and south samples is reported.
An Assessment Of Age Determination Methods For Captured Passerine Birds, William P. Mueller, Charles M. Weise
An Assessment Of Age Determination Methods For Captured Passerine Birds, William P. Mueller, Charles M. Weise
Field Station Bulletins
Various methods of determining age of passerine birds, using eye color, shape of flight feathers, plumage color patterns, etc. are presented in handbooks for bird banders, such as Pyle, et al., Identification Guide to North American Passerines (1987). We compared several such methods with the standard, reliable (but time-consuming) method, "skulling", in 22 species of passerines captured and banded during Fall 1994, in a general netting operation at the University of Wisconsin-Milwaukee Field Station. In many species these methods were in agreement; however in 10 species there was substantial disagreement, especially involving buffy covert tips in thrushes and shape of …
Effects Of Management And Site History On Plant Succession And Seedbank Composition In Old-Fields At The Uwm Field Station, Beth A. Krause, Diane De Steven
Effects Of Management And Site History On Plant Succession And Seedbank Composition In Old-Fields At The Uwm Field Station, Beth A. Krause, Diane De Steven
Field Station Bulletins
Vegetation succession and seedbank composition were studied in eleven oldfields with differing crop histories. All the fields had been abandoned from agriculture in the mid-1960's, and some fields are currently receiving periodic management in the form of burning, mowing, and/or removal of exotic species. Oldfield plant composition was found to be most strongly influenced by management history since abandonment. Recently-managed fields had a greater abundance of certain early-successional nonnative species in the herbaceous layer, whereas unmanaged fields contained greater abundances of many later-successional, native perennial herb species. Woody plants showed the most significant response to management. Woody plant densities and …
