Food webs describe the networks of these relations. While the population dynamics of individual species are often highly variable (Bjornstad and Grenfell, 2001), the overall structure of the trophic relations of the community, its food web, is comparatively more stable as they exhibit remarkably ...
As we confront the reality of the ongoing human-driven mass extinction (1), attention often focuses on the response of individual species to environmental change. However, species survival also depends on other species in the food web: Changing population numbers or extinction of one species can ...

All living things are connected, especially when it comes to eating and being eaten. Food chains and food webs are ways of showing the food relationships between organisms in any given environment, from the African savanna to the coral reef. If one plant or animal is affected, all the others...
Biodiversity is also very important to the stability of food webs. Damage to them can mean disaster for an entire ecosystem. The extinction of a single animal species can put huge pressure on the numerous other species dependent on it.Biodiversity also has an important ro...
this function and in doing so, kill the beetle,"said Halberg. "There is twenty times as much insect biomass on Earth than that of humans. They play key roles in most food webs and have a huge impact on virtually all ecosystems and on human health. So, we need to unde...
Use a bug barrier productto help prevent insect infestations, which in turn attract spiders. Be sure to read the label carefully and use all spider control products as directed. FIND SOLUTIONS FOR SPIDERS Explore our family of products designed to help you get tough in the fight against spiders...
Fisheries have affected food webs in a variety of ways, including the depletion of species at all trophic levels from abalone to sharks. Pauly et al. have proposed that "fishing down marine food webs" is ubiquitous, based on declining trends in mean trophic level (MTL) in global catches. ...
Spiders want to be left alone and like dark, quiet areas like closets, basements, andattics where there are plenty of places build undisturbed webs. Cardboard boxes are particularly attractive to a spider because it can find other insects to prey on. You can reduce the number of spiders in...
