Performance of the models for the omnivorous European minnow and the herbivorous grass carp was poor, while models for the piscivorous mandarin fish and Chinese snakehead provided accurate predictions of growth.
Among them,there are 8 families,30 species of herbivorous insect,5 families,29 species of pollination insect insect,10 families,73 species of autoeciousness insect,6 families 13 species of predacity insect.
The energy density of carnivorous Carabidae (22 64 J/mg AFDW) was significantly higher than herbivorous Tenebrionidae (20 55 J/mg AFDW),but their difference in water content (54 96% and 63 28% respectively) was converse ( P <0 05).
Annual species even index of forest plant community showed a positive relation with that of parasitical insect community, a negative relation with that of herbivorous insect community, namelyE P; ant =0.621-0.401* Ez-0.0427* Eb+0.574* Ej, and little relation with predatory insect community.
The developmental models and the techniques of grazing and raising management for herbivorous livestock, the management models of intensive agriculture were explored, which have been promoting the economical development of the north part of Henan Province.
His area of rangeland is large, the grass yield of rangeland is high and the animal carrying potentialities are great, but the grazing utilization ratio is low for the present, the herbivorous livestock is small in quantity.
Mercury concentrations in planktons, benthos, herbivorous fish, omnivorous fish, carnivorous fish and water fowl in vivo are 0.34, 0.48, 0.90, 1.28, 1.70 and 3.29 ppm, respectively, in estuary of Jiyun Riyer.
According to relations among nutrient levels in food web,the 49 species of fishes were divided into three nutrient levels:(1) Herbivorous and mixed feeding animal,the nutrient levels of which were 1.0-1.3 and 1.4-1.9,respectively.
Total nitrogen requirements in the small herbivorous rodent Microtus rossiaemeridionaliswere studied.
It was proposed that the consumption of a low-fiber diet (about 4% in both kinds of food) could affect the gastrointestinal bacterial flora and, thus, lead to changes in the primarily herbivorous nitrogen metabolism.
Morphological and biochemical adaptations to feeding in some herbivorous gastropods
Feeding range and modes as well as morphological and biochemical adaptations to feeding are analyzed in herbivorous mollusks.
Determination analysis confirms the theoretic assumptions on food preferences of herbivorous fish: both silver and bighead carps avoided feeding on cyanobacteria.
