Plant Biodiversity Enhances Bees and Other Insect Pollinators in Agroecosystems. a Review Plant Biodiversity Enhances Bees and Other Insect Pollinators in Agroecosystems. a Review
Thirty-five percent of global production from crops including at least 800 cultivated plants depend on animal pollination. The transformation of agriculture in the past half-century has triggered a decline in bees and other insect pollinators. In North America, losses of bee colonies have accelerated since 2004, leaving the continent with fewer managed pollinators than at any time in the past 5...
متن کاملTropical and Subtropical Agroecosystems
SUMMARY Thyroid hormones and their receptors in the ovaries are active regulators of reproductive function; both hyper-and hypo-thyroidism may result in estrous cycle disturbances. In addition, thyroid hormones elicit an extraordinary multiplicity of biochemical, cellular, and physiological responses, both in the simplest and the most complex organisms. On the other hand, glutamate, the main ex...
متن کاملSampling Scarab Beetles in Tropical Forests: The Effect of Light Source and Night Sampling Periods
Light traps have been used widely to sample insect abundance and diversity, but their performance for sampling scarab beetles in tropical forests based on light source type and sampling hours throughout the night has not been evaluated. The efficiency of mercury-vapour lamps, cool white light and ultraviolet light sources in attracting Dynastinae, Melolonthinae and Rutelinae scarab beetles, and...
