The boreal zone land cover has a very significant influence on the northern hemisphere albedo and is an important component of the northern hemisphere carbon budget [1, 2] and is sensitive to changes in local and global climate [3]. Forest transition zones react to changes in mean temperature and moisture conditions in the long term [4] whereas changes in, for example, forest leaf area index (L...

"Climate" and "Participation" are among the subject that have attracted the attention of authorities and those interested in individual, group, and organizational behavior during the recent decades. This study aims to review the history and the meaning of climate and participation in the organizational area and to study the relationship between these two variables. Using a q...

Projected changes in climate conditions are emerging as significant risk factors to numerous species, affecting habitat conditions and community interactions. Projections suggest species range shifts in response to climate change modifying environmental suitability and is supported by observational evidence. Both pathogens and their hosts can shift ranges with climate change. We consider how cl...

Food security and economic welfare strongly depend on agricultural production, the loss of this production can be a serious challenge for food security and economic welfare. Agricultural production is also influenced by environmental and climatic factors so that the variations of climatic parameters can trigger extensive fluctuations in agricultural production. This study classifies climate cha...

paper undertakes software based numerical simulations in two different traditional houses in cold-dry climate of tabriz and hot-arid climate of yazd, the eco test software chosen for bim simulations. case study on real houses instead of hypothetical models can give more tangible results and choosing traditional houses can provide a good opportunity to compare both physical and thermal condition...

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

Climate change poses threats to human health, safety, and survival via weather extremes and climatic impacts on food yields, fresh water, infectious diseases, conflict, and displacement. Paradoxically, these risks to health are neither widely nor fully recognized. Historical experiences of diverse societies experiencing climatic changes, spanning multicentury to single-year duration, provide in...

Determining the response of dominant height growth to climate change is important for understanding adaption strategies. Based on 550 permanent plots from a national forest inventory and climate data across seven provinces and three climate zones, we developed a climate-sensitive dominant height growth model under a mixed-effects model framework. The mean temperature of the wettest quarter and ...

BACKGROUND Older adults make up 13% of the U.S. population, but are projected to account for 20% by 2040. Coinciding with this demographic shift, the rate of climate change is accelerating, bringing rising temperatures; increased risk of floods, droughts, and wildfires; stronger tropical storms and hurricanes; rising sea levels; and other climate-related hazards. Older Americans are expected to...
