Mico humeralifer (É. Geoffroy Saint-Hilaire, 1812) is a callitrichid monkey commonly called the Santarémmarmoset or black-and-white tassel-eared marmoset. It is a small (280–310 g), sexually monomorphic anthropoid primate with a diet of insects, fruits, and plant exudates (nectar and gum). It is endemic to northern Brazil, occurring in the states of Pará and Amazonas, south of the Rio Amazonas,...

Considering the current state of the Zagros forests and the necessity of using information related to quantitative characteristics in the management of these forests, it is essential to prepare more accurate information so that the control of this area can be done more accurately. One of the ways to obtain statistical information is linear sampling (transect.( In this regard, the present study ...

Mangrove forests are one of the most productive and carbon dense ecosystems that are only found at tidally inundated coastal areas. Forest canopy height is an important measure for modeling carbon and biomass dynamics, as well as land cover change. By taking advantage of the flat terrain and dense canopy cover, the present study derived digital surface models (DSMs) using stereo-photogrammetric...

The Northern Spotted Owl (Strix occidentalis caurina) is an emblematic, threatened raptor associated with dense, late-successional forests in the Pacific Northwest, USA. Concerns over high-severity fire and reduced timber harvesting have led to programs to commercially thin forests, and this may occur within habitat designated as “critical” for spotted owls. However, thinning is only allowed un...

Many contemporary semi-arid forests of western North America are denser and have a greater proportion of shade tolerant species relative to preEuro-American settlement. While many causes have been invoked to explain these changes, the active suppression of fire since the early 1900s has been the most widely studied and cited. However, widespread logging in western North American forests has oft...

Pinus ponderosa Laws. (ponderosa pine) forests have changed considerably during the past century, partly because recurrent fires have been absent for a century or more. A number of studies have explored the influence of timber harvest or burning on understory production in ponderosa pine forests, but study designs incorporating cutting and prescribed burning in an experimental framework are nee...

This research examines the impact of forest management regimes, with various degrees of restriction, on forest conservation in a dry deciduous Indian forest landscape. Forest change is mapped using Landsat satellite images from 1977, 1990, 1999, and 2011. The landscape studied has lost 1478 km2 of dense forest cover between 1977 and 2011, with a maximum loss of 1002 km2 of dense forest between ...

Forest soils represent a significant pool for carbon sequestration and storage, but the factors controlling soil carbon cycling are not well constrained. We compared soil carbon dynamics at five broadleaf forests in the Eastern US that vary in climate, soil type, and soil ecology: two sites at the University of Michigan Biological Station (MI-Coarse, sandy; MI-Fine, loamy); Bartlett Experimenta...

India has one of the largest assemblages of tropical biodiversity, with its unique floristic composition of endemic species. However, current forest cover assessment is performed via satellite-based forest surveys, which have many limitations. The present study, which was performed in the Eastern Ghats, analysed the satellite-based inventory provided by forest surveys and inferred from the resu...

Background and purpose: The objectives of our study were to identify invasive alien plant species (IAS) in the main Natura 2000 forest habitat types (FHT) along the Mura River in Slovenia, and to estimate their abundance and cover. The aim of our study was to find out a) Which IAS appear in the research forests? b) What is their frequency and cover percentage? c) Whether individual IAS prosper ...
