Trophic interactions in soils as they affect energy and nutrient dynamics. IV. Flows of metabolic and biomass carbon
Over the 24-day experiment, respiration was significantly higher in the microcosms containing the bacterial grazers and the amoebae allocated more carbon to tissue production and correspondingly less to CO2, with partitioning of available carbon by the microfauna varied considerably. Expand
An annotated list of the non-marine mollusca of Britain and Ireland.
Readers should note especially the following changes to species names: substitution of Oxyloma sarsii for Oxyloma sarsi (misspelling); substitution of Mytilopsis leucophaeata for MytilopsisExpand
Habitable pore space and microbial trophic interactions
It is concluded that microbial trophic structure in relation to soil texture and habitable pore space is an important factor influencing energy flow in terrestrial ecosystems. Expand

The present study is an initial report of the concentration of cadmium, copper, lead, and zinc in 35 genera of aquatic macroinvertebrates collected in the Fox River, Illinois, and Wisconsin.
Two new species of Hirschmanniella Luc and Goodey, 1963 (Nematoda: Pratylenchidae) with a key to the nominal species
Hirschmanniella anchoryzae n. sp. from Canada and Hirschmanniella areolata n. sp. from Hong Kong are described and illustrated. The former is characterized by a flattened head, stylet length of 16–17Expand
Bioconcentration patterns of zinc, copper, cadmium and lead in selected fish species from the Fox river, Illinois
The whole body concentrations of Zn, Cu, Cd and Pb were related to the whole body dry weights of blue-gill, black crappie, blackBullhead, black bullhead, and yellow perch on the basis of their importance as recreational and food species and their frequent use in both field and laboratory studies.

The distribution of Cd, Cu, Pb and Zn in the biota of two freshwater sites with different trace metal inputs
The concentrations of Cd, Cu, Pb, and Zn were determined in the abiotic and biotic components at two sites in the Fox River, Illinois. Analysis of the metals was completed on solutions of wet ashedExpand
Habitat selection in two species of short-horned grasshoppers
The roles of thermal and hydric stress in habitat selection by two species of short-horned grasshoppers was investigated through field and laboratory studies and computer simulation experiments and showed that the habitat selected by P. delicatula would allow behavioral thermoregulation whereas the habitat chosen by E. simplex should preclude regulation of body temperature by behavioral means.

Organic and inorganic nitrogenous losses by microbivorous nematodes in soil
To examine the relationship between primary and secondary decomposers and N mineralization in soil, amino acid-N, NH'-N, and population dynamics were measured in a soil microcosm system employing:Expand
