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 ...

We have only meagre knowledge of the composition and the functions performed by vegetation in Wisconsin cities. The records of the U.S. Government Land Survey conducted in the 1830s provide information on the presettlement ...

Since 1966 the winter populations of Dark-eyed Juncos, Junco hyemalis at the UWM Field Station have been monitored by mark-recapture methods. Schnabel estimates with 95% confidence intervals are presented for each winter. ...

The linear-leaf sundew has been extirpated from several stations at the southern edge of Its range. Cedarburg Bog is believed to harbor the largest of the remaining southern colonies of this species. Drosera linearis has ...

Aquatic invertebrates of Wisconsin have been studied extensively, but until recently, little work has been done with aquatic oligochaetes (segmented worms). Much of the previous work was primarily concerned with the tubificid ...

Floristic and seed bank composition of a sedge meadow containing purple loosestrife was examined in 1987 and 1988. Eleocharis spp., Spiraea tomentosa, Triadenum vircrinicum, and Lycopus spp. were widespread while infrequent ...

Three contrasting urban areas in Milwaukee County were sampled to determine the tree species reproducing and the habitats in which seedlings become established. Habitats most favorable for seedling establishment were shrub ...

Within 100 years after settlement began (ca. 1830), most forest land in the Milwaukee area had been influenced by agriculture. When the land was cleared for cultivation, trees were occasionally left along property boundaries, ...

Marginal populations are those located at the extreme or periphery of a species' range. In the context of this paper, marginal populations refer to a geographical periphery rather than to possible ecological margins. A ...
