Assessing habitat-related disturbance in bird communities: Applying hemeroby and generalism as indicators

The effects of habitat fragmentation on bird communities in Hyrcanian forests (Case study: Gorgan Township)

Species–energy relationships and habitat complexity in bird communities

Allen H. Hurlbert* Department of Biology, University of New Mexico, Albuquerque, NM 87131, USA *Correspondence: E-mail: [email protected] Abstract Species–energy theory is a commonly invoked theory predicting a positive relationship between species richness and available energy. The More Individuals Hypothesis (MIH) attempts to explain this pattern, and assumes that areas with greater food resou...

assessing metacognitive awareness and learning strategies as positive predictors in promoting l2 learners’ reading comprehension

the purpose of this thesis was to investigate how differently metacognitive, cognitive, and social/affective strategies affect l2 learners’ reading comprehension. to this end, the study employed a quasi-experimental design with a placement test as a proficiency test to find the homogeneity of groups. three classes were randomly selected as the experimental groups (n =90), and each class was tau...

Assessing log extraction related soil disturbance and solutions to protect soil and reduce disturbance of forest ecosystem.

Skid trails are the main routes for wood extraction and also the main source of runoff and sediment production in Forests. This research was conducted in Kuhmiyan forest of Golestan Province to determine infiltration, compaction, strength (resistance to penetration) and moisture content in three treatment including control (in the forest), wheel ruts and middle of skid trail were measured in th...
