sensitive coastal areas are fragile ecosystems affected by geographic features and in the same time settlements were developed around these areas due to their ecological capability. coastal ecosystems due to their countless benefits are very important for protection. hence, this paper attempts to determine the sensitivity of coastal ecosystem to disturbances in hormozgan province. we reviewed 2...

Growth in transportation networks, resource extraction, motorized recreation and urban development is responsible for chronic noise exposure in most terrestrial areas, including remote wilderness sites. Increased noise levels reduce the distance and area over which acoustic signals can be perceived by animals. Here, we review a broad range of findings that indicate the potential severity of thi...

This essay analyzes the use of fire on Upland Island Wilderness Area (UIW) to examine how postindustrial wilderness sites rework operative notions nature, wildness, and preservation within U.S. environmental thinking politics. Postindustrial areas complicate conceptualizations nature as pristine, unspoiled, or even beautiful, challenging us address biodiversity ecosystem function in ways that a...

In a recent national survey of federal wilderness managers, respondents identified the high priority need for scientific information about public attitudes toward biophysical intervention to adapt to climate change and attitudes of the public toward restoration of natural conditions. In a survey of visitors to one National Park wilderness in California, visitors revealed that they largely do no...

Fire management has always meant fire suppression to the managers of the chaparral covered southern California National Forests. Today, Forest Service fire management programs must be cost effective, while wilderness fire management objectives are aimed at recreating natural fire regimes. A cost-effectiveness analysis has been developed to compare fire management options for meeting these objec...

High species richness is thought to support the delivery of multiple ecosystem functions and services under changing environments. Yet, some species might perform unique functional roles while others are redundant. Thus, the benefits of high species richness in maintaining ecosystem functioning are uncertain if functions have little redundancy, potentially leading to high vulnerability of funct...

C onservation biology, as developed and practiced in the United States, has the explicit aim of maintaining and encouraging biodiversity. The term “biodiversity” was introduced in 1986 by Walter Rosen as a shorthand for “biological diversity.” Although Rosen’s original intention was quite precise, biodiversity, according to a survey of US conservation biologists, has become a fashionable scient...
