The paper highlights the growing concern of the impact of climate change and variability including rainfall anomaly, rising temperature in mountain areas and occurrence of heat waves in relation to human mortality pattern in India. The paper investigates the historical perspective of rainfall and malaria relationship, and cited current studies to show how climate change and variability resulted...

The high resolution and span diversity of colored Google Earth images are the main reasons for developing a vegetation extraction mechanism based on BPNN (Back Propagation Neural Networks) that can work efficiently with poor color images. This paper introduces a method based on neural networks that can efficiently recognize vegetation and discriminate its zone from the desert, urban, and roadst...

The article describes the chemical composition of newly irrigated, developed sandy-desert, old-irrigated alluvial-meadow, newly-irrigated gray-brown-meadow, gray-earth-meadow soils, common in lower and middle reaches Zarafshan River, decrease amount nutrients soil under influence anthropogenic factors. In arable subarable layers old irrigated meadow-alluvial humus is 0.859-0.971% 0.715-0.894%, ...

One of the key repercussions desertification process in Sahara and Arabian desert is increased aeolian sand drift deposition. Despite its isolated location severe climate—particularly terms solar radiation, drift, deposition—the region El-Oued Souf Grand Erg Oriental Algerian has been a cultural trade center for many centuries. To resist extreme weather conditions, architecture vernacular settl...

BACKGROUND The often dramatic effects of urbanization on community and ecosystem properties, such as primary productivity, abundances, and diversity are now well-established. In most cities local primary productivity increases and this extra energy flows upwards to alter diversity and relative abundances in higher trophic levels. The abiotic mechanisms thought to be responsible for increases in...

abstract. from the perspectives of many environmental and conservative policy makers, improving and diversifying the livelihoods have been found as a mechanism to promote the livelihoods and persuade people to avoid the overexploitation and degradation of natural resources. due to the fragility of the environment and inconsistency of incomes, the alternative income sources may be promised to wa...

Ants that fall prey to the raids of army ants commonly respond by evacuating their nests. This documented behavior has been underexploited by researchers as an efficient research tool. This study focuses on the evacuation response of the southwestern desert ant Aphaenogaster cockerelli André (Hymenoptera: Formicidae) to the army ant Newamyrmex nigrescens Cresson. It is shown that army ants can ...
