A comparison of the responses of two tropical specialist herbivores to host plant patch size
(Springer-Verlag, 1986-03)
The effects of host plant patch size on the abundances of two specialist herbivores (the chrysomelid beetle, Acalymma innubum and the pentatomid bug, Piezosternum subulatum ) were investigated in a natural forest community ...
Purification and properties of an oxygen-evolving reaction center complex from photosystem II membranes : A simple procedure utilizing a non-ionic detergent and elevated ionic strength
(Elsevier, 1986-03-03)
A method is reported for the isolation of a highly resolved oxygen-evolving photosystem II reaction center preparation. This preparation can be separated from the more complex photosystem II membranes isolated by the ...
Benzoylarginine peptidase and iminopeptidase profiles of Treponema denticola strains isolated from the human periodontal pocket
(Springer-Verlag; Springer-Verlag New York Inc., 1986-03)
Seven clinical isolates and the ATCC strain 35405 of Treponema denticola , obtained from human periodontal pockets, were studied for peptidase activity with several chromogenic compounds as substrates. The cell sonicates ...
A reaction-diffusion system of a predator-prey-mutualist model
(Elsevier, 1986-04)
Mutualism is part of many significant processes in nature. Mutualistic benefits arising from modification of predator-prey interactions involve interactions of at least three species. In this paper we investigate the ...
Optimal foraging and community structure: implications for a guild of generalist grassland herbivores
(Springer-Verlag, 1986-08)
A particular linear programming model is constructed to predict the diets of each of 14 species of generalist herbivores at the National Bison Range, Montana. The herbivores have body masses ranging over seven orders of ...
Rapid expression of novel proteins in goldfish retina following optic nerve crush
(Elsevier, 1986-08-14)
SummaryPolyadenylated messenger RNA was isolated from goldfish retinas at various times following unilateral crush of the optic nerve. RNA was translated in a cell-free system and product proteins analyzed by two-dimensional ...
Kappa receptor mediated opioid dependence in rhesus monkeys
(Elsevier, 1986-09-15)
The kappa receptor-selective agonist U-50, 488 was administered chronically to rhesus monkeys. Tolerance developed to the overt behavioral effects of U-50, 488 without cross-tolerance to morphine. Withdrawal behaviors ...
Prediction of protein function by discriminant analysis
(Elsevier, 1986-10)
Approximately 53% the protein sequences in the National Biomedical Research Foundation (NBRF) database can be allocated to one of 26 functional classes, each of which can be characterized by the joint occurrence of four ...
Conservation of chloroplast genome structure among vascular plants
(Springer-Verlag, 1986-07)
We have constructed the first physical map of a gymnosperm chloroplast genome and compared its organization with those of a fern and several angiosperms by heterologous filter hybridization. The chloroplast genome of the ...
Isolation and structure of the Streptococcus faecalis sex pheromone, cAM373
(Elsevier, 1986-09-29)
The Streptococcus faecalis sex pheromone, cAM373, which induces a mating response of donor cells harboring plasmid pAM373 and is also produced by Staphylococcus aureus, was isolated and its structure determined. Supernatant ...
