Stress in forest ecosystems (FES) occurs as a result of land-use intensification, disturbances, resource limitations or unsustainable management, causing changes in forest health (FH) at various scales from the local to the global scale. Reactions to such stress depend on the phylogeny of forest species or communities and the characteristics of their impacting drivers and processes. There are m...

Forest fire or wild land fire causes adverse ecological, economic and social effects worldwide. Globally, forest fires are considered as one of the major drivers of climate change having deleterious impacts on the earth and environment as studies reveal their significance in producing large amounts of trace gases and aerosol particles, which play a pivotal role in tropospheric chemistry and cli...

We report on the design and implementation of ecological monitoring for an Australian biodiversity conservation incentive scheme - the Environmental Stewardship Program. The Program uses competitive auctions to contract individual land managers for up to 15 years to conserve matters of National Environmental Significance (with an initial priority on nationally threatened ecological communities)...

forest management as one of the important source of production is crucial and critical. in taking over the forest resources as one of the most important of natural resources in the world, it is essential to consider local stakeholders to implement forest action plan for forest co-management. therefore, this study aims at achieving to proper management of forests based on evaluating the stakehol...

The papers in this special issue address a major challenge facing our society: feeding a population that is simultaneously growing and increasing its per capita food consumption, while preventing widespread ecological and social impoverishment in the tropics. By focusing mostly on the Amazon's most dynamic agricultural frontier, Mato Grosso, they collectively clarify some key elements of achiev...

prosopis cineraria (l.) druce (kahour in persian) is a native and indicative species of saharo-sindian region. prosopis forest in iran extends from the beach of persian gulf and oman sea in boushehr, hormozgan and sistan-baluchistan provinces to south of kerman province. in this research ecological conditions of prosopis such as floristic diversity, climate, soil and the biomass were studied. i...

Loss of tropical forests is a major cause of biodiversity loss worldwide. Although drastic modification of the habitat has been shown to negatively affect amphibians, we are far from a complete understanding of the response of amphibian communities to deforestation. We studied frog assemblages in a gradient of forest modification in a humid area of Costa Rica, where the primary forest has been ...

spatial pattern of trees can possibly indicate stand history, population dynamics, and species competition. this research was investigated in the chahartagh forest reserve, ardal region, chaharmehal and bakhtiari province, central zagros forest, and southwest iranian state. in this study 53 hectare of the study area was selected and perfect inventory.  information includes the position and kind...

land use change may influence many natural phenomena and ecological processes, including runoff, soil erosion, sedimentation and soil conditions. decreasing of forest area in the north of iran is one of the critical problems in recent years. the aims of this study are to detect land use changes between 1967 to 2002 using satellite images of land sat 7 etm+ (2002), aerial photos and digital topo...

Forest biomass and carbon are critical for ecological monitoring, yet poorly modelled in complex ecosystems such as the tropical rainforests. To overcome this challenge incurred due to comp...
