Little information has been published on selection of tree roosts by eastern pipistrelles (Perimyotis subflavus) in forested environments, and no radiotelemetry-based studies have been conducted on males in forested settings. Therefore, we used radiotelemetry to characterize summer roost selection by 21 male (33 roosts) and 7 female (14 roosts) eastern pipistrelles during 6 years in a forested ...

The most comprehensive dataset of in situ destructive sampling measurements of forest biomass in Eurasia have been compiled from a combination of experiments undertaken by the authors and from scientific publications. Biomass is reported as four components: live trees (stem, bark, branches, foliage, roots); understory (above- and below ground); green forest floor (above- and below ground); and ...

plane and mulberry trees play a crucial role in purifying the polluted air in tehran as a majorcity. in this research, 13 main districts of tehran city were chosen as study area. 20 completely healthy planeand mulberry species were selected in similar ecological conditions and age range. the uptake of cd and pbwas determined using spectrophotometry, whereas the chlorophyll content was measured ...

Allergy is becoming a major disease burden globally. Pollens are considered as the main component of aeroallergens that lead to rhinitis and asthma. Due to the lack of a comprehensive investigation on most allergic pollens of trees in the Middle East, the present study aimed to conduct a comprehensive literature review on this topic. The main goal of the study was to provide a checklist for all...

that 286,000 ha in Arkansas were affected by the oak decline. In 2002 and 2003, Guldin et al. (2006) established 181 field plots in Arkansas, Missouri, and Oklahoma and estimated that 33% of red oak density (trees/ha) and 30% of red oak basal area in the region were dead or dying. Kabrick et al. (2004) studied nine forested sites in southern Missouri ranging in size from 312 to 514 ha. They rep...

Ecology Letters (2010) 13: 1503-1514 ABSTRACT: The phylogenetic structure and distribution of functional traits in a community can provide insights into community assembly processes. However, these insights are sensitive to the spatial scale of analysis. Here, we use spatially explicit, neighbourhood models of tree growth and survival for 19 tree species, a highly resolved molecular phylogeny a...

The forest ecology literature is rife with debate about how to: (i) define a ‘forest’ and distinguish it from similar systems, such as woodlands, savannas, parklands or plantations; (ii) identify transitions from ‘forested’ to ‘non-forested’ states and, most challengingly; (iii) quantify intensities of degradation. Here we argue that past attempts to define forests and forest degradation, focus...

the present study aims at discussing whether metaphors in the qur’an, revealed more than 1400 years ago, are dead, moribund or live and how these three types of metaphors have been translated in three english and three persian translations of the qur’an. the results reveal that among 70 metaphors examined, while only about 32.85% are live metaphors, about 67.14% are moribund, but none of the ca...
