Bryophytes Of Rocky Branch Nature Preserve, Clark County, Illinois, David C. Burnette
Bryophytes Of Rocky Branch Nature Preserve, Clark County, Illinois, David C. Burnette
Masters Theses
An extensive field survey of the Rocky Branch Nature Preserve in Clark County, Illinois, revealed a total of 52 bryophyte species. Of these, 38 were mosses and 14 were liverworts. Descriptions, habitats and distribution comments, plus a map showing the county distributions for each species in Illinois are included.
As a result of this survey, the liverwort Nardia lescurii (Aust.) Underw. is a new addition to the bryoflora of Illinois. There were also several other bryophytes found that were previously unreported for Clark County or the Rocky Branch Nature Preserve. These include Rhynchostegium pulchellum (Hedw.) Robins var. pulchellum, Isopterygium …
A Key To The Hepaticae Of Coles And Clark Counties, Illinois, Michael J. Klopmeyer
A Key To The Hepaticae Of Coles And Clark Counties, Illinois, Michael J. Klopmeyer
Masters Theses
This study represents a taxonomic survey of the hepaticae of east-central Illinois. The counties included in this study were Coles and Clark, located in the east-central portion of the state, near the Indiana stateline. Of the areas included in this study, two are in Clark county, Rocky Branch and Rocky Hollow, and one in Coles county, Rock's Park.
The influence of the Wisconsin glacier, and its terminal moraine located in southern Coles county, greatly influenced the topography and ultimately the specific habitats for the hepaticae. The majority of the liverworts encountered in these counties are found in the numerous sandstone …
Moss Sensitivity To Sulfur Dioxide, John W. Wilcut
Moss Sensitivity To Sulfur Dioxide, John W. Wilcut
Masters Theses
Extensive research regarding the effects of sulfur dioxide (SO2) on vascular and nonvascular plants has been reported. Sulfur dioxide has been shown to interrupt normal metabolism, to interrupt normal reproduction, and to alter the plant's morphology.
One hypothesis regarding the lack of bryophytes in urban areas is that the life cycle is being interrupted. It has been shown that moss protonemata are sensitive to SO2 concentrations in urban areas. Several authors noted that sexual reproduction is blocked among many species which do occur in urban environments. Observations on protonemal sensitivity are probably more important than the observations …
