Influence of abiotic environmental factors on forest insects,Light rays of different wavelengths exercise various direct or indirect influences on insects. Besides visible radiation (0.4 < λ ? 0.7 μm), provide heat and thus increase body temperature, as well as ultraviolet rays of 0.4-0.003 ?m wavelength, which may have important chemical, and consequently biological, effects on living protoplasm.作者: Condescending 時間: 2025-3-24 04:58 作者: 技術(shù) 時間: 2025-3-24 10:35 作者: originality 時間: 2025-3-24 12:55 作者: chemical-peel 時間: 2025-3-24 17:57 作者: craven 時間: 2025-3-24 21:11 作者: diathermy 時間: 2025-3-25 01:21

Insects in forest biocenoses,osis in time is due to the various relationships which occur between the organisms in that biocenosis and which form a complex structure of trophic, paratrophic and competitive interspecific dependences. Each species finds food and shelter from its enemies and holds a definite position in the functional and spatial structure of the biocenosis.作者: Lineage 時間: 2025-3-25 09:32
