FORUM Insect herbivore relationship to the state of the host plant: biotic regulation of ecosystem nutrient cycling through ecological succession
This paper provides a conceptual framework for increasing our understanding of the relationships between plant resistance to insect herbivores and insect herbivore influences on ecosystem nutrient cycling and succession. For a given plant species, adequate nutrient/light availability favors establishment and productivity; small insect herbivore populations regulated by plant biochemistry stimul...
متن کاملComparison of Ecological Patches' Potentials and Functions in Rangeland Ecosystems (Case Study: Qahavand Rangelands, Hamedan Province, Iran)
Interrupting the processes which control ecosystem resources has dramatic impacts on the rangeland conditions. To protect ecosystems and landscape, it needs to understand the ecosystem processes which regulate the ecosystem resources. As main components of ecosystems, patches and inter-patches play important roles in energy and materials cascade. Ecologically, functional parameters such as stab...
متن کاملProductivity and Nutrient Cycling in the Early Postburn Chaparral Species Lotus scoparius1
2 Postdoctoral Researcher, University of California, Irvine, Calif. Abstract: The frequent fires in southern California have a pronounced influence on many aspects of chaparral shrub communities, particularly nutrient relationships. Nutrient accumulation, and productivity were studied for the post fire species Lotus scoparius. This stand of Lotus scoparius was approaching maximum biomass yet th...
متن کاملNutrient Cycling in Forests of the Pacific Northwest
Ecosystem analysis has established nutrient cycling as an important area of ecology involving biological, chemical, and geological interactions. Studying the flow of elements through ecosystems provides us with a tool for understanding the functioning of ecosystems. For example, if an ecosystem component has a rapid flux of elements through it, or if it stores large amounts of an element, that ...
متن کاملNutrient levels within leaves, stems, and roots of the xeric species Reaumuria soongorica in relation to geographical, climatic, and soil conditions
Besides water relations, nutrient allocation, and stoichiometric traits are fundamental feature of shrubs. Knowledge concerning the nutrient stoichiometry of xerophytes is essential to predicting the biogeochemical cycling in desert ecosystems as well as to understanding the homoeostasis and variability of nutrient traits in desert plants. Here, we focused on the temperate desert species Reaumu...
