The expansion of oil palm plantations at the expense of tropical forests is causing declines in many species and altering ecosystem functions. Maintaining forest-dependent species and processes in these landscapes may therefore limit the negative impacts of this economically important industry. Protecting riparian vegetation may be one such opportunity; forest buffer strips are commonly protect...
The aim of this work was to monitor the ornithic community forest Vallombrosa Biogenetic National Nature Reserve, in Florence area. covers about 1273 hectares, at an altitu...
Unlike the virgin forest in the Changbaishan Nature Reserve in northeastern China, little research on a landscape scale has been conducted on secondary forests in the region under conditions of a warming climate. This research was undertaken in the upper Hun River region where the vegetation is representative of the typical secondary forest of northeastern China. The spatially explicit forest l...
Premontane forest in northern Argentina and southern Bolivia represents a conservation priority due to its biological values, role of connectivity among different forest types, and precious timber resources. Premontane forest distribution has fluctuated in correspondence to habitat use and changes in climatic conditions. The objective of this study was to determine current and future distributi...
Here we present a three-year survey of amphibian and reptile species registered in the Vale Natural Reserve (VNR), located north Espírito Santo, southeastern Brazil. The VNR, along with Sooretama Biological (SBR) other surrounding areas, form forest block that constitutes one largest remnants continuous Atlantic Forest biome. We systematically sampled herpetofauna community from 2015 to 2018, u...
Current research on forest change monitoring using medium spatial resolution Landsat satellite data aims for accurate and timely detection of forest disturbances. However, producing forest disturbance maps that have both high spatial and temporal accuracy is still challenging because of the trade-off between spatial and temporal accuracy. Timely detection of forest disturbance is often accompan...
We initiated a study of the effects of mycorrhizal fungal community composition on the restoration of tropical dry seasonal forest trees. Tree seedlings were planted in a severely burned experimental site (1995 fire) during the growing season of 1998 at the El Edén Ecological Reserve, in north Quintana Roo, Mexico. Seedlings of Leucaena leucocephala, Guazuma ulmifolia, Caesalpinia violacea, Pis...
Deforestation leads to the deterioration of soil fertility which occurs rapidly under tropical climates. Forest rehabilitation is one of the approaches to restore soil fertility and increase the productivity of degraded areas. The objective of this study was to evaluate and compare soil biological properties under enrichment planting and secondary forests at Tapah Hill Forest Reserve, Perak aft...
In this study we investigated the relationship between the sensitivity to forest fragmentation of bird species and their habitat spatial distribution. We hypothesized that a homogenous spatial distribution is associated to habitat-generalist species, which would tend to be less sensitive to forest fragmentation; in contrast, a heterogeneous spatial distribution would drive to an increase of sen...
The Biligiri Rangaswamy Temple (BRT) Tiger Reserve is a biodiverse region of peninsular India that harbors significant number endemic and near-endemic angiosperm species. present documentation reveals total 211 taxa conserved in this reserve. Analysis show the flora dominated by Western Ghats (57%) elements, followed Eastern elements (28%), (9%), Indian (6%). study reports two species Syzygium ...
