    Spatial and seasonal variation in soil respiration rates were investigated in a tropical dry forest in Thailand. The spatial variation was examined at 50 points within a 2-ha plot in the forest floor during the dry and wet seasons.

      The correction of LST by these topographic factors allowed to detect a dependence of LST on the fraction of non-forested area. Accordingly, the relationship between LST and the fraction of non-forested area showed a positive linear relationship (R2 = ), whereby each 25% increase of non-forest area resulted in increased 1°C. Introduction. The global demand for forests and forest products is increasing because of population growth. To meet this demand, the importance of plantations has increased because they have high wood-production rates compared with natural tion forest production meets two-thirds of the global industrial roundwood ore, plantation forests are reducing the pressure on.

      Forest transitions (FT) have been observed in many developed countries and more recently in the developing world. However, our knowledge of FT from tropical regions is mostly derived from case studies from within a particular country, making it difficult to generalize findings across larger regions. Here we overcome these difficulties by conducting a recent (–) satellite-based.   The factors that control the distribution of tropical forest and savanna have puzzled ecologists for over a century, and yet there is still only limited consensus on the relative importance of ‘bottom‐up’ (resource‐dependent) and ‘top‐down’ (disturbance‐dependent) controls, and the exact mechanisms by which these factors operate.

The relationship between forest clearing and ecological zone and the influence of topography, soils, and transportation network are presented and discussed.

used logistic regression to assess the relationship between the transition to forest and 21 biophysical, socioeconomic, and landscape variables.

We found that the percentage of forest cover within a m radius of a point, distance to primary roads and nature reserves, slope, and aspect are the most important predictors of forest recovery. The present study aimed to clarify the relationship between psychological responses to forest and urban environmental settings and the physical variables that characterize these environments, by examining the psychological responses of subjects to their physical environment.

The relationship between humans and the natural world appears to be a universal concern of Western thought, occupying a central place in Greco-Roman, Arab, and European mythology and philosophy (see Human–Environment Relationships).

Tropical forests have an important regulating influence on local and regional climate, through modulating the exchange of moisture and energy between the land and the atmosphere. Deforestation disrupts this exchange, though the climatic consequences of progressive, patch-scale deforestation of formerly intact forested landscapes have not previously been assessed.

Is active restoration the best approach to achieve ecological restoration success (the return to a reference condition, that is, old-growth forest) when compared to natural regeneration in tropical forests. Our meta-analysis of studies demonstrated that natural regeneration surpasses active restoration in achieving tropical forest restoration success for all three biodiversity groups.

Tropical forest habitat continues to decline globally, with serious negative consequences for environmental sustainability. The small mountain country of Nepal provides an excellent context in which to examine trajectories of forest-cover change.

Despite having experienced large-scale forest clearing in the past, significant reforestation has taken place in recent years. Lao People’s Democratic Republic (PDR) has been experiencing significant forest depletion since the s, but there is little evidence to demonstrate the major causes and underlying drivers for the forest cover changes.

In this study, we investigated the relationship between forest cover decrease and increase in the south of Lao PDR between and and selected physical and socio.

The earth’s ability to receive and absorb sunlight is a primary factor in the earth’s environment, and it also has a big impact on human populations. There is a direct relationship between highlands and type B climates in various places in the world. Tropical rain forests only make up about 5 percent of the earth’s surface but.

The biophysical feedbacks of forest fire on Earth’s surface radiative budget remain uncertain at the global scale. Using satellite observations, we show that fire-induced forest.

Mexico City: Book Review: Recent dynamics of the Mediterranean vegetation and landscape. Most of the prime agricultural land in tropical Latin America, for example, was stripped of forest centuries ago; more recent conversions have taken place on marginal lands, leading to a cycle of pasture creation, land degradation, and the pushing of the agricultural frontier further into erstwhile forest cores (Hecht, ; Moran et al., ).

Forests and riverine and floodplain ecosystems. Forests provide several indirect functions that support riverine and floodplain ecosystems.
