Effects Of Landscape Structure On Plants Species Richness In Small Grassland Remnants In Two Different Landscapes, S. A. O. Cousins, O. Eriksson

IGC Proceedings (1997-2023)

There is an increasing interest in using the landscape as the operational scale in many ecological studies. Current species richness in the landscape may be explained by past land use, and habitats may harbour species favoured by an environment that no longer exists. In this study we have included both a landscape scale and a temporal scale. The objective was to explain species pattern and the effect of isolation, habitat size and surrounding land use, and past land use change, on small grassland remnants in rural landscapes.

Jane Claire Dirks's Correspondence With Stanley G. Jewett, Jane Claire Dirks-Edmunds, Stanley G. Jewett

Jane Claire Dirks-Edmunds Documents

This exchange between Jane Claire Dirks (later Jane Claire Dirks-Edmunds) and Stanley G. Jewett, a biologist with Region 1 of the Fish and Wildlife Service (serving Oregon and five other states), is an example of the type of correspondence Dirks had with various experts on the Pacific forest region while she was completing her doctoral thesis. Dirks-Edmunds began to study Zoology in Illinois immediately after earning her Bachelor's degree in Biology from Linfield College in 1937. She returned to teach in the Biology department at Linfield from 1941-1974.

Comparison Of Biotic Communities Of The Cedar-Hemlock And Oak-Hickory Associations, Draft Version, Jane Claire Dirks-Edmunds

Jane Claire Dirks-Edmunds Documents

This early, typewritten draft of the doctoral dissertation by Jane Claire Dirks (later Jane Claire Dirks-Edmunds) contains her edits and notes. Dirks-Edmunds's project compared the Douglas fir forest community on Saddleback Mountain in Oregon to an oak-hickory forest near her graduate school in Illinois.

Dr. Dirks-Edmunds graduated from Linfield College in 1937; she later returned to teach in the Biology department at Linfield from 1941-1974.

Reflections On Plant And Soil Nematode Ecology: Past, Present And Future, Howard Ferris, Bryan S. Griffiths, Dorota L. Porazinska, Thomas O. Powers, Koon-Hui Wang, Mario Tenuta

Department of Plant Pathology: Faculty Publications

The purpose of this review is to highlight key developments in nematode ecology from its beginnings to where it stands today as a discipline within nematology. Emerging areas of research appear to be driven by crop production constraints, environmental health concerns, and advances in technology. In contrast to past ecological studies which mainly focused on management of plant-parasitic nematodes, current studies reflect differential sensitivity of nematode faunae. These differences, identified in both aquatic and terrestrial environments include response to stressors, environmental conditions, and management practices. Methodological advances will continue to influence the role nematodes have in addressing the nature of …

Habits And Life History Of The Bronze Flea Beetle, Altica Tombacina (Mannerheim) (Coleoptera-Chrysomelidae), Jane C. Dirks-Edmunds

Jane Claire Dirks-Edmunds Documents

This article, which was published in volume 39 issue 4 of the journal Northwest Science, describes a study that began in the fall of 1959 and was supported by federal grant G-8779. Dr. Jane Claire Dirks-Edmunds's research focused on the little-known Bronze Beetle and involved several of her contemporaries, both within and outside the Linfield College Biology Department.

Letter From Lawrence W. Quate To Dr. Jane C. Dirks-Edmunds, Lawrence W. Quate

Jane Claire Dirks-Edmunds Documents

This letter from Dr. Lawrence W. Quate is one of many such letters received by Dr. Jane Claire Dirks-Edmunds. Dirks-Edmunds consulted a number of experts to help identify the specimens she collected while conducting fieldwork. Quate was an expert on midges, also known as psychodids. Many of the colleagues with whom Dirks-Edmunds corresponded resided far afield from her research site on Saddleback Mountain in Oregon.

Dirks-Edmunds, a 1937 graduate of Linfield College, graduated from the University of Illinois in 1941; she returned to teach in the Biology department at Linfield from 1941-1974.

Saddleback Research Project Collection Tabulation, Dorwin Lovell

Jane Claire Dirks-Edmunds Documents

This student inventory of insects found on Saddleback Mountain is part of Dr. Jane Claire Dirks-Edmunds's ecological study of the area. The physical collection of the Dr. Jane Claire Dirks-Edmunds Papers (see collection information below) includes similar tabulations from multiple classes at Linfield, all documenting insect type and number found. Dr. Dirks-Edmunds compiled her students' research into various reports on her study's progress.

Dr. Dirks-Edmunds graduated from Linfield College in 1937; she returned to teach in the Biology department at Linfield from 1941-1974.

Biotic Succession In A Douglas Fir Forest On Saddleback Mountain (Oregon Coast Range), Jane Claire Dirks-Edmunds

Jane Claire Dirks-Edmunds Documents

This grant proposal, submitted to the National Science Foundation in 1959 by Dr. Jane Claire Dirks-Edmunds, requested funding to continue an ecological study at Saddleback Mountain. Dirks-Edmunds requested $15,570.05 to fund weekly trips with students to the site in order to collect meteorological and synecological data on the forest; she anticipated the project would last two years.

Dr. Dirks-Edmunds graduated from Linfield College in 1937; she returned to teach in the Biology department at Linfield from 1941-1974.
