Notes On Two Species Of Plants At The Margins Of Their Ranges In Cedarburg Bog, James A. Reinartz
Notes On Two Species Of Plants At The Margins Of Their Ranges In Cedarburg Bog, James A. Reinartz
Field Station Bulletins
In June 1983 two large patches of Fringed Polygala were found in the Cedar-Tamarack woods at the north end of Cedarburg Bog. These patches had obviously been established for a number of years but the species had never previously been noticed in the bog. These Ozaukee County populations are southern disjuncts separated by at least 60 miles from the main part of the species' distribution.
Recognition Of Brood-Mate Vocalizations By Northern Bobwhite (Colinus Virginianus) Chicks, Susan St. Clair Raye
Recognition Of Brood-Mate Vocalizations By Northern Bobwhite (Colinus Virginianus) Chicks, Susan St. Clair Raye
Field Station Bulletins
Unrelated bobwhite quail (Colinus virginianus) chicks were hatched together and raised together. Each chick was tested in an arena with tape recorded separation, contentment and distress calls from a brood-mate and an unfamiliar chick of the same age. Chicks at one, six and 19 days of age gave significantly more separation calls in response to the separation calls of their brood-mates than they gave in response to the separation calls of the strange chicks. Since the chicks were not related, this ability to recognize brood-mate vocalizations is probably learned. Sibling recognition in quail might function in inbreeding avoidance.
Ecological Studies Of The Surface Microlayer Of Small Ponds At The Uwm Field Station, Charles C. Remsen, James S. Maki, Savas C. Danos, Kenneth E. Estep
Ecological Studies Of The Surface Microlayer Of Small Ponds At The Uwm Field Station, Charles C. Remsen, James S. Maki, Savas C. Danos, Kenneth E. Estep
Field Station Bulletins
The seasonal variation and enrichment of nutrients, pigments, bacteria, fungi and algae in the surface microlayer and subsurface waters were investigated in three ponds at the University of Wisconsin-Milwaukee Field Station, Saukville, Ozaukee County, Wisconsin. Samples were collected intermittently from June, 1978 through October, 1981. Microlayer samples were collected using a glass plate and a screen sampler. All ponds showed dramatic seasonal variations in nutrients, microorganisms and algae in both surface and subsurface waters. The data indicate that physical factors such as adsubble processes, antirain and atmospheric deposition, along with biological factors such as heterotrophic mineralization and autotrophic uptake, play …
The Ecology Of A Moth Associated With The Northern Pitcher Plant (Sarracenia Purpurea), Glenn R. Guntenspergen, Charles R. Rupprecht
The Ecology Of A Moth Associated With The Northern Pitcher Plant (Sarracenia Purpurea), Glenn R. Guntenspergen, Charles R. Rupprecht
Field Station Bulletins
Endothenia daeckeana Krft. is an obligate associate of S. purpurea L. in Wisconsin. This paper presents a preliminary analysis of the ecological relationship between this moth and its host plant.
Underwing Moths At The Uwm Field Station, Maria Plonczynski
Underwing Moths At The Uwm Field Station, Maria Plonczynski
Field Station Bulletins
This paper summarizes the findings of my study (1977-1982) of the presence and phenology of moths in the genus Catocala at the UWM Field Station. Use of sugar bait and black light traps resulted in the capture of 19 species. This report includes a phenological list of the specimens and line drawings of each, depicting size and hindwing coloration.
The Dominance Hierarchy Of The Black-Capped Chickadee And It's Relation To Breeding Territory And Frequency Of Visitation To An Artificial Food Source, Craig Thompson
Field Station Bulletins
A peck-dominant type of dominance hierarchy was demonstrated in a group of twenty-one Black-capped Chickadees and was consistent with what is expected of this species of Paridae at the interflock level. No significant correlations were found between dominance and frequency of visitation to the study feeder, between dominance and distance from feeder to 1980 breeding territory, and between distance to territory and frequency of visitation.
