Aim To assess the impact of certain climatic variables on the breeding success of some populations of Bonelli’s eagle (Hieraaetus fasciatus V. 1822) throughout its latitudinal distribution range, in order to account for recent and differential declines in populations. Location Western Mediterranean, from southern Morocco to southern France. Methods Seven populations were considered for the lati...

BACKGROUND In this study, we aim to identify key climatic factors that are associated with the transmission of Japanese encephalitis virus in areas located near the Three Gorges Dam, between 1997 and 2008. METHODS We identified three geographical regions of Chongqing, based on their distance from the Three Gorges Dam. Collectively, the three regions consisted of 12 districts from which study ...

This article presents modelling and control of a climatic chamber with on/off actuators. Controlled environmental variables in the chamber are temperature, relative humidity and illumination. The system is first decoupled by nonlinear transformation and a linear model is identified using subspace methods; further, a model predictive control strategy for processes with on/off actuators is presen...

climate change is a phenomenon that has made the most concern in communities and decision making centers. this phenomenon has important effects on different aspects of human life. one of the most important crops that are affected by climate change is wheat. accordingly, data and information of northern khorasan have been used to study the effects of climate change on rain-fed wheat yield. for t...

We analyzed the effects of population density and climatic variables on the rate of population growth in the guanaco ( ), a wild camelid species in Lama guanicoe South America. We used a time series of 36 years (1977-2012) of population sampling in Tierra del Fuego, Chile. Individuals were grouped in three age-classes: newborns, juveniles, and adults; for each year a population transition matri...

Both climatic and edaphic conditions determine plant distribution, however many species distribution models do not include edaphic variables especially over large geographical extent. Using an exceptional database of vegetation plots (n = 4839) covering an extent of ∼55,000 km2, we tested whether the inclusion of fine scale edaphic variables would improve model predictions of plant distribution...

Ecological niche modeling (ENM) is a broadly used tool in different fields of plant ecology. Despite the importance of edaphic conditions in determining the niche of terrestrial plant species, edaphic data have rarely been included in ENMs of plant species perhaps because such data are not available for many regions. Recently, edaphic data has been made available at a global scale allowing its ...

The study was designed for mapping the filariasis transmission risk using geo-climatic variables. The application of remote sensing and GIS in the present study is mainly focused on profiling the areas at risk of filariasis transmission. The filariasis disease is caused by the Culex genus mosquito vector. The survival and longevity of infected filariasis vector mosquitoes are spatially determin...
