the main objective of an ecosystem sustainable management is to preserve itscapacity to respond and adapt to current disturbances and/or future changes, and maintain theprovision of environmental goods and services. two very important properties linked to thisobjective are the ecosystem resilience and resistance to disturbance factors. the objective ofthis paper is to recommend conceptual modif...
Rangeland ecosystems provide a wide range of services such as gas regulation function whose economic value has not been understood. The present study aimed to estimate the economic value of CO2 absorption and oxygen generation services using unit price in Sheikh Musa Rangeland, Mazandaran Province, Iran. In the study area, clipping and weight and photosynthesis methods were applied to estimate ...
The several ways termites interact with the plant-soil-litter system are outlined in a conceptual web of pathways to show how distinct actions of termites may impact ecosystem functioning, either positively or negatively. That is, because of their several modes of feeding and nesting, termites may act as agents of decomposition or pedogenesis, pests, competitors of grazing livestock, or as sour...
Aesthetic is an added value to other precious values of rangelands and helps its ecosystem conservation. Unfortunately, there is not plenty of researches run on this issue and its probable value. Instead emphasis has put on ecosystem management especially on the basis of marketable products. In this study, the people willingness to pay for the aesthetic of Sarbijan rangeland landscapes and its ...

Beginning in the early 1980s, conservation biologists adapted neoliberal economics to reframe ecosystem functions and related biodiversity as ecosystem services to humanity. Despite the economic success of pro...
Declines in species diversity carry profound implications for ecosystem functioning. Communities of primary producers and consumers interact on evolutionary as well ecological time scales, shaping complex relationships between biodiversity In subsidized ecosystems, resource inputs are independent consumer actions, offering a simplified view the relationship function higher trophic levels. With ...
