The objective of this study was to select Pinus kesya progenies by the estimation of genetic parameters using the method of restricted maximum likelihood (Reml) and prediction of additive genetic values by the best linear unbiased prediction (Blup). The Pinus kesya progeny test was installed in randomized blocks, which consisted of 30 progenies and three replications. The twenty-year-old trees ...
selection cutting using skidding system often causes physical damage to residual stand through felling and skidding resulting decline of bole quality and tree value. this research evaluated logging damage using skidding system on residual trees and stand regeneration in uneven aged hardwood forest of asalem, were selection cutting was practiced. in this regard, systematic sampling method was us...

—Northern Hawk Owls (Surnia ulula) have been reported to cache prey during the breeding season for later consumption, but detailed reports of prey caching during the non-breeding season are comparatively rare. We provided prey to four individual Northern Hawk Owls in wintering areas in northeastern Minnesota during 2001 and 2005 and observed their caching behavior. These owls cached 93% (n 14) ...
We conducted dendroclimatic and stable isotope analyses of lodgepole pines (Pinus contorta) located in high-mortality sites at Mammoth Mountain (California, USA) to test for tree responses to magmatic degassing. Existing climatic and tree-ring data from nearby Yellowstone National Park were used for comparison. Sampled trees were scarcely sensitive to climate, and their growth showed an overall...
Effects of live and dead (heat-killed) infective juveniles (IJs) of the entomopathogenic nematode Steinernema carpocapsae on nematodes associated with boxwood Buxus spp. were evaluated in field experiments during 1999 and 2000. Both living and dead IJs of S. carpocapsae were equally effective, causing more than 50% reduction in total populations of plant-parasitic nematodes relative to the cont...
abstract 1 most tree characteristics such as annual growth ring are influenced by climatic changes. dendroclimatology, a branch of dendrochronology science, studies the effects of climate parameters such as temperature and precipitation on the characteristics of annual growth ring. to carry out this research, 30 quercus persica coppice trees were selected in oak forest in khorramabad, l...
