The vegetation cover and rangeland production are the most important factors to determine the proper planning system for effective utilization and management of rangelands. In this research, the effect of climatic factors (temperature and rainfall) were studied on vegetation cover and forage production of four species (Festuca ovina, Bromus tomentellus, Dactylis glomerata and Agropyron trichoph...

Drought is a complex phenomenon which can be characterised mainly by its severity, duration and areal extent. Among these three dimensions, drought severity is the key factor which can be used for drought analysis. Drought indices are typically used to assess drought severity in a meaningful way. DrinC (Drought Indices Calculator) is a software package which was developed for providing a simple...

Air pollution is responsible for many adverse effects on human beings. Thermal discomfort, the other hand, able to overload body and eventually provoke health implications due heat imbalance. Methods: The aim of presented work study behavior two bio-climatic indices statistical characteristics air quality index Sofia city—the capital Bulgaria period 2008–2014. based WRF-CMAQ model system simula...

Global climate change affects biodiversity patterns, especially in arid and semi-arid regions such as the Mongolian plateau, one of most ecologically fragile world. Three dynamic habitat indices (DHIs) were related to productivity hypothesis calculated based on FAPAR, including cumulative (DHIcum indicates availability resources food supply a year, representing available energy), minimum (DHImi...

Lepidopteran stem borers are among the most important pests of maize in East Africa. The objective of the present study was to predict the impact of temperature change on the distribution and abundance of the crambid Chilo partellus, the noctuid Busseola fusca, and their larval parasitoids Cotesia flavipes and Cotesia sesamiae at local scale along Kilimanjaro and Taita Hills gradients in Tanzan...

El Niño Southern Oscillation (ENSO) is the most important large-scale circulatory phenomenon that causes climatic variability in northern Mexico. The current challenge is to understand its consequences for both local climate and ecological processes of ecosystems. Within this context, we compared the degree of association of three different ENSO indices with local seasonal precipitation (P) in ...

in recent years, interest in climatic extreme events (droughts, floods and heat waves) has been growing not only due to their direct impact on many socio-economic sectors, but also as climate change indicators. in this study, the behavior of extreme events is investigated using extreme climate index software (ecis) package. the trend analysis of extreme indices is applied to daily series of tem...
