The odoriferous glands of some Palpatores Phalangida (Opiliones) (Arachnida)
(The University of Saskatchewan, 1971)The odoriferous glands of especially Phalangium opilio and to a lesser extent Opiliones parietinus, Odiellus pictus, Homolophus biceps, Leiobunum calcar and L.. vittatum were investigated by: external examination; dissection; ... -

Selective predation in a polyphagous invertebrate predator, Pardosa vancouveri (Arachnida, Araneae)
(Simon Fraser University, 1979)Selective predation (i.e., non-random feeding) was studied in a laboratory system that allowed individual lycosid spiders, Pardosa vancouveri. to feed on prey populations consisting of one or two kinds of insects. Various ... -
Selective predation in a euryphagous invertebrate predator, Pardosa vancouveri (Arachnida, Araneae)
(Canadian Entomologist, 1982)Selective predation (i.e., non-random feeding) was studied in a laboratory system that allowed individual lycosid spiders, Pardosa vancouveri, to feed on prey populations consisting of one or two kinds of insects. Various ... -
Laboratory work in distance education
(Distance Education, 1982)A major concern in distance education is how to overcome the problems associated with laboratory components of courses. In this paper we review the general importance of laboratory work for students, summarise the ... -
A blind Homolophus biceps (Arachnida, Opiliones)
(Entomological News, 1983)Scanning electron microscopy of a harvestman, Homolophus biceps. that lacked both eyes and ocular tubercle revealed no indication of external damage or healing. Internally, light microscope sections showed no evidence ... -
Strategies of subcellular fractionation suitable for analysis of peroxisomes and microperoxisomes of animal tissues.
(International Journal of Biochemistry, 1983)Strategies of subcellular fractionation are reviewed from the perspective of their utility in the analysis of peroxisomes. The considerable potential inherant in the method of rate dependent banding In zonal rotors is ... -
High fat diets and mouse colon mucosal membranes: a centrifugation study.
(Cancer Letters, 1983)Female Swiss mice were fed on a control diet (laboratory chow, 6% fat) or high fat diets (laboratory chow with added fat, principally corn oil, to produce a fat content of 16% or 23%). Homogenate of colon mucosa ... -
Refined carbohydrates - a cause of suboptimal nutrient intake.
(Medical Hypotheses, 1983)During the refining of carbohydrate foods there is a sharp drop in the concentration of dietary fiber and of various vitamins and minerals. Estimates were made of the effect of refining on the total diet intake of ... -
Coronary heart disease - dietary lipids or refined carbohydrates?
(Medical Hypotheses, 1983)The epidemiological evidence associating dietary lipids, refined carbohydrates and coronary heart disease (CHD) is evaluated. Population studies often show a high correlation between dietary lipid and heart disease ... -
Relating feeding rates to sex and size in six species of grasshoppers (Orthoptera: Acrididae).
(Canadian Entomologist, 1984)Nymphs and adults of both sexes of six species of grasshoppers. Camnula pellucida, Dissosleira carolina, Melanoplus infantilis. M. sanguinipes, M. packardii and M. bivillalus, were fed wheat seedlings to determine daily ... -
Overwintering aggregations of Leiobunum paessleri in caves and mines (Arachnida, Opiliones).
(Journal of Arachnology, 1984)In the forested mountain areas of southwestern Canada, Leiobunull1 paessleri (Roewer) form overwintering aggregations in the twilight regions of moist caves and mines. Each aggregation consists of adults of both sexes ... -
High-Fat Diets and Fecal Level of Reductase and Colon Mucosal Level of Ornithine Decarboxylase, B-Glucuronidase, 5'-Nucleotidase, ATPase, and Esterase in Mice.
(Journal of the National Cancer Institute, 1984)In one experiment Swiss mice were maintained on a 16 or 23% fat diet (laboratory chow with added fat, principally corn on) or on laboratory chow alone (5.5% fat), In another experiment CS7BU1 mice were given a 23% fat ... -
Simplicity - the key to fruitful medical research
(Medical Hypotheses, 1985)Medical research is here divided -into two broad categories. The great majority of research is "complex" and includes all studies of intricate body mechanisms. A minority of research is "simple" and deals mainly ... -
Dietary fats in health
(Journal of Nutrition, Growth and Cancer, 1985)This review examines the relationship between dietary fat intake and health. ,Heal produced by modem farming methods has a high fat content in comparison with its natural counterpart and, furthermore, the fat is low in ... -
The scent glands of Opiliones: a review of their function.
(Smithsonian Institution Press, 1986)Opilionids are unique among the arachnids in that they possess a pair of glands that open dorsally near the lateral edge of the prosoma. These glands are variously called scent, odoriferous, repugnatory, or stink glands ... -
