This study used pitfall trapping to examine community composition and diversity of ground beetles in five different habitats (coniferous, deciduous, mixed coniferous, farmland, and settlements) within Anhui Yaoluoping National Nature Reserve from May to September 2014. In total, 1,352 ground beetles were collected, belonging to 16 genera and 44 species. Of these, four dominant species Dolichus ...
all of the tea plantations in iran are concentrated in the caspian sea region on soils previously developed under deciduous natural forests. this research conducted to study the effect of land use change (from forest to tea) on selected physico-chemical and mineralogical properties of soils under humid climate and mountainous landscape in northern iran. three transects facing west to northwest ...
6 [1] This study examined daily streamflow response over up to four decades in northwest 7 conifer forest and eastern deciduous forest sites in the United States. We used novel 8 methods to analyze daily observations of climate and streamflow spanning more than 9 900 basin years of record at 14 treated/control basin pairs where forest removal and 10 regrowth experiments were underway in the per...

The seasonal abundance patterns of insects inhabiting the understory vegetation of a mixed deciduous forest were examined with the help of the sweep-net sampling method. During the study period of 2 years, insects were sampled regularly from the understory vegetation of the three selected habitats (moist-deciduous, riverine, and teak plantation) of the mixed deciduous forest. Insect abundance w...
OF THESIS Use of Landsat Data to Characterize Burn Severity, Forest Structure and Invasion by Paulownia (Paulownia Tomentosa) in an Eastern Deciduous Forest, Kentucky Landsat imagery has been used successfully to assess burn severity and monitor postfire forest structure in a variety of ecosystems, but to date there are few documented studies on its application in the eastern deciduous forests ...
Phenological events, such as bud burst, are strongly linked to ecosystem processes in temperate deciduous forests. However, the exact nature and magnitude of how seasonal and interannual variation in air temperatures influence phenology is poorly understood, and model-based phenology representations fail to capture local- to regional-scale variability arising from differences in species composi...
Human-induced forest modification can alter parasite-host interactions and might change the persistence of host populations. We captured individuals of two widespread European passerines (Fringilla coelebs and Sylvia atricapilla) in southwestern Germany to disentangle the associations of forest types and parasitism by haemosporidian parasites on the body condition of birds. We compared parasite...
Time series (2003 to 2007) MERIS Terrestrial Chlorophyll Index (MTCI) products were used to predict the phenology of different forest types in India. The MTCI data were corrected for noise using a temporal moving window filter and then a Fourierbased smoothing was applied without compromising annual phenological cycle. Finally, the phenological variables i.e. onset of greenness and end of senes...
Nutrient pulses can facilitate species establishment and spread in new habitats, particularly when one species more effectively uses that nutrient pulse. Biological differences in nutrient acquisition between native and exotic species may facilitate invasions into a variety of habitats including deciduous forest understories. Alliaria petiolata (Bieb.) Cavara & Grande is an important invader of...
