abstract different responses of silkworm larvae under various rearing climate condition would help to obtain better economic performance of some silkworm varities in specific climate conditions. the effect of 4 rearing climate conditions including 1) standard 2) high temperature and humidity, 3) high temperature and low humidity and 4) temperature fluctuation were investigated on the performanc...

knowledge of behavior climatic indexes can be help to planning future programs bahabad study area in the eastern part of the province of yazd with a hot and dry climate, high potential evapotranspiration and low rainfall has a high potential for desertification. the aim of this research is evaluation of classification intensity by imdpa model with emphasis to climate criteria. the indices inclu...

purpose: to evaluate the prevalence and risk factors of dry eye in the patients referred to an eye clinic in birjand, iran. methods: this cross sectional descriptive-analytical study consisted of 600 patients who were referred to the eye clinic of birjand, iran between september 2010 and september 2011. they were given a simple questionnaire about the risk factors of dry eye including the demog...

To meet the ever increasing and diversified food demand, the production needs to be doubled from the available resources which are already under stress. Dry lands cover 40% of the world’s land area spread in 55 countries, having 2.5 billion people out of which one third people depend on agriculture. Dry lands ha...

A significant amount of recent research has focused on the potentially synergistic roles of climate change and disease in causing amphibian declines and extinctions. Herein I discuss the drought-linked chytridiomycosis hypothesis (DLCH), which states that prolonged or intensified dry seasons trigger or exacerbate epidemics of chytridiomycosis, a potentially lethal skin disease of amphibians cau...

Background: The tropical dry forest, the most endangered ecosystem in the Neotropics, is threatened by the dominance of extensive conventional cattle ranching. The consequences of this land use system are particularly evident in the dry forest ecosystem of Panama’s Azuero Peninsula. Deforestation and soil degradation have impaired ecosystem services, which are necessary to support ranching and ...

Current models for seasonal climate prediction are limited due to poor initialization of the land surface soil moisture states. Passive microwave remote sensing provides quantitative information on soil moisture in a thin near-surface soil layer at large scale. This information can be integrated with a land surface process model through data assimilation to give better prediction of the near su...

A number of studies use meteorological records to analyze climate trends and assess the impact of climate change on agricultural yields. While these provide quantitative evidence on climate trends and the likely effects thereof, they incorporate limited qualitative analysis of farmers' perceptions of climate change and/or variability. The present study builds on the quantitative methods used el...

Understanding adaptive genetic responses to climate change is a main challenge for preserving biological diversity. Successful predictive models for climate-driven range shifts of species depend on the integration of information on adaptation, including that derived from genomic studies. Long-lived forest trees can experience substantial environmental change across generations, which results in...

The ability of coupled GCMs to correctly simulate the climatology and a prominent mode of variability of the West African monsoon is evaluated, and the results are used to make informed decisions about which models may be producing more reliable projections of future climate in this region. The integrations were made available by the Program for Climate Model Diagnosis and Intercomparison for t...
