To gain a better understanding of the factors affecting selection of reproductive habitat by female fishers (Martes pennanti) in boreal mixed-wood forests, we identified structures, sites, and stands used by 12 radiotagged female fishers for reproduction between 2005 and 2009 near Dawson Creek, British Columbia, Canada. We deployed a used-unused design to evaluate the support by the data for a ...

The detection of veterinary antibiotics (VAs) in drinking water resources resulting from manure disposal operations has raised public health concerns. Previous studies have demonstrated the benefits of using multispecies vegetated buffer strips (VBS) to reduce agrichemical transport from agroecosystems. However, VA fate and subsequent effects of VAs on microbial activities in the root zone ofVB...

Black locust is an interesting option for biomass production at sites prone to water shortage because the species combines water-use efficiency and a yield largely superior that of poplars under conditions study. (Robinia pseudoacacia L.) tree woody production. However, its potential this purpose has been much less studied characterized than from Salicaceae family (i.e., poplar willow). The obj...

We evaluated the biomass and contents of five major macronutrients (N, P, K, Ca and Mg) in 10-year-old poplar trees (Populus deltoids Bartr. cv. "Lux"), and determined their nutrient use efficiencies (NUEs) at Zhoushan Forestry Farm (32°20' N, 119°40' E), Jiangsu province, in eastern China. The above- and below-ground biomass of poplar trees was 161.7 t ha(-1), of which 53.3% was stemwood. The ...

Elm and poplar are two tree species that can provide a large amount of low-value feedstock for biochar production due to their rapid growth rate (poplar), susceptibility disease and/or infestation (both elm poplar). Biochar has been studied recently as filtration medium water purification, it provides renewable alternative activated carbon. In this work, the adsorption efficiency biochars made ...

Poplar improvement efforts are directed at improving tree traits such as rapid early growth, yield, and fiber quality. The goal of improvement programs is to increase resistance to diseases that have the potential to reduce yields or kill trees. Selection, breeding, and testing for poplar disease resistance are hampered by the long generation time of trees, the difficulty in identifying and cap...

Poplar has emerged as a model plant for better understanding cellular and molecular changes accompanying tree growth, development, and response to environment. Long-term application of different forms of nitrogen (such as [Formula: see text]-N and [Formula: see text]-N) may cause morphological changes of poplar roots; however, the molecular level changes are still not well-known. In this study,...
