Objectives: To broaden the genetic information base of Juniperus and resolve phylogeny polycarpos through sequencing characterization its chloroplast genome. Methods: The (cp) genome J. was sequenced assembled using Next-Generation Sequencing pairedend reads platform BGISEQ-500 annotated CpGAVAS. phylogenetic analysis performed in MEGA7. Findings: Here, we report complete cp sequence polycarpos...
The main ecological services of the sand-fixed forest are windbreak, soil erosion control, and atmospheric dust retention. In this paper, the ecological services of Populus simonii forest were assessed by simultaneous measurements of wind speeds, daily amount of soil surface wind erosion, and amount of atmospheric dust deposition at different observation sites located within and outside the for...
In most cases authors are permitted to post their version of the article (e.g. in Word or Tex form) to their personal website or institutional repository. Authors requiring further information regarding Elsevier's archiving and manuscript policies are encouraged to visit: a b s t r a c t a r t i c l e i n f o U.S. forests, including family-owned forests, are important carbon sinks and sources f...
Mollisol soil is a major contributor to food production. Clarification of the molecular characteristics dissolved organic matter (DOM) will contribute overall understanding and management mollisol soil. However, complexity DOM poses challenge its characteristics. In this study, we investigated (< 1 000 Da) in soils with different use patterns (forestland dryland) based on untargeted metabolomic...
To identify the soil carbon stock changes from croplands/grasslands to forestlands in Japan, we compared of a cropland/grassland with that an adjacent forestland at 22 different sites. With respect 0–30-cm depth basis, was same as forestland; however, it less than when equivalent mass approach used. The ratio 1.11 on average, which is comparable previous mass-corrected paired sampling studies. ...
The land use and cover pattern of the Qinghai-Tibet Plateau (QTP) is an important basis for structure function QTP ecological barrier. It great significance to simulate landscape risk under future scenarios construction barrier area promote sustainable resources. was selected as study area.

This research evaluates the potential gains in benefits from using Goal Programming to preserve forestland. Twoand three-dimensional Goal Programming models are developed and applied to data from applicants to the U.S. Forest Service’s Forest Legacy Program, the largest forest protection program in the United States. Results suggest that not only do these model yield substantial increases in be...
We modeled hunting demand among resident hunters in the Southeastern United States. Our model revealed that future hunting demand will likely decline in this region. Population growth in the region will increase demand but structural change in the region's demography (e.g., "browning" and "aging "), along with declining forestland access will decrease hunting demand. The results suggested that ...
