Based on comparative ethnographic research in four countries and three continents, Butinage: The Art of Religious Mobility explores the notion of "religious butinage" as a conceptual framework intended to shed light on the dynamics of everyday religious practice. Derived from the French word butiner, which refers to the foraging activity of bees and other pollinating insects, this term is employed by the authors metaphorically to refer to the "to-ing and fro-ing" of believers between religious institutions.

AbstractExamination of crop contents of three species of grasshoppers in outbreak densities on desert grassland of eastern Arizona revealed that all three were ingesting a mixed diet of plants. Crops of nymphal and adult Aulocara elliotti (Thomas) contained an average of 67 and 93% dry weight of grass, respectively, placing this species in both the mixed graminivorous and the graminivorous categories. The preferred host plant of A. elliotti was Bouteloua gracilis (H.B.K.) Lag. but it was not an essential item, as a large population developed in a site where this grass was virtually lacking but other perennial grasses were present. Crops of nymphs and adults of both Melanoplus sanguinipes (Fabricius) and M. cuneatus Scudder contained chiefly forbs (88–100% of dry weight). The principal host plants were Erodium cicutarium (L.) L’Hér., Lupinus brevicaulis Wats., Microsteris gracilis (Hook.) Greene, and Plantago purshii Roem. & Schult. Both species of Melanoplus fit into the forbivorous category and evidence indicated they were in competition with each other for food. All three grasshopper species showed preferences for particular plant species and as a consequence had significantly different frequencies of plant taxa in their crop contents from what were present in the field.

Tin (Sn) is one of the causative elements of the environmental pollution. As no certified reference materials for Sn are presently available, existing reference materials were analyzed for Sn by two independent analytical techniques; atomic absorption spectrometry (AAS) and neutron activation analysis (NAA). The results obtained by both methods were in agreement except for mixed diet which contains Sn in the range of 50 μ g/g. Further, tin concentrations in human and animal organs have been examined by AAS. Among organs tested tin concentrations in testes were the highest, 2.08±0.62 μ g/g dry weight (mean ±SD, n=12) in humans, and 1.45±0.55 μ g/g (n=8) in mice.

The Mean

To determine the effects of diet mixing on digestive performance, harbour seals (Phoca vitulina L., 1758) were offered either pure diets of Pacific herring (Clupea pallasii Valenciennes, 1847) or walleye pollock (Theragra chalcogramma (Pallas, 1814)) or a 1:1 mix of herring and pollock. Regardless of diet, retention time decreased approximately 40% as intake quadrupled. The mean apparent digestible dry matter (ADDM) was greatest on mixed diets during low feeding frequency trials; ADDM during high feeding frequency trials was significantly reduced as intake increased for animals on the single-species (pollock or herring) diets. As intake increased, up to 45% more digestible energy was assimilated from the mixed diet than from either single-species diet. The findings of this study suggest that a mixed diet consisting of prey differing in lipid and protein amounts increased digestible energy intake in harbour seals. Our measures of intake and ADDM in harbour seals revealed digestive flexibility and indicated that digestion in harbour seals was more efficient on a mixed diet.
