Correlative species distribution models are based on the observed relationship between species' occurrence and macroclimate or other environmental variables. In climates predicted less favourable populations are expected to decline, and in favourable climates they are expected to persist. However, little comparative empirical support exists for a relationship between predicted climate suitabili...

Eighty-one cultivars from 12 field crop species were assessed for suitability as hosts to the root lesion nematode, Pratylenchus neglectus, in two field trials. Host status was assessed on the basis of either final P. neglectus densities in soil or multiplication rate under different crops. Both techniques gave consistent results for crop and cultivar ranking, and it was therefore concluded tha...

A large amount of Software Visualization (SV) technology has been developed This is particularly the case for the Prolog programming language whose execution model causes particular difficulties for the learner (e.g. Taylor, 1988; Fung et al; 1990; Schertz et al, 1990). As a result, a wide range of Prolog SVs (or tracers) exist and though many claims are made regarding their usefulness and suit...

Cell-based Multicriteria Evaluation (MCE) methods are used to analyse the land suitability evaluation. Land evaluation is carried out to estimate the suitability of land for a specific use such as arable farming or irrigated agriculture. land suitability evaluation is a prerequisite for land-use planning and development (Sys 1985; Van Ranst and others 1996). It provides information on the const...

Suitability analysis is performed to identify sites (usually grid cells or pixels) suitable for a specific purpose so that management decisions can be made in a site-specific manner. However, sites identified as suitable are rarely equally suitable in the real world. Measurement of the degree of site suitability (DoSS) is therefore crucial to be able to manage sites in a truly site-specific man...

Present study is an attempt to examine the suitability of soil moisture products available from Aqua-AMSR-E for their application in monsoon simulations at different temporal scales ranging from medium range to climate scales. For this purpose we have analysed the AMSR-E soil moisture products over 18 locations in India to evaluate their suitability for assimilation in numerical models. It has ...

Considering the poor condition of most rangelands of Iran, evaluation of rangeland potential and determination of suitability for continuous and optimal utilization seems necessary. The purpose of this study was to investigate the rangeland suitability for sheep and goat grazing using FAO and GIS methods. Therefore, three criteria including vegetation cover, water, and soil were studied. The ...

a primary uses from iran rangelands is livestock grazing and the major livestock is sheep. sheep grazing on the slopes above 60%, because of using a lot of energy for grazing operation, caused to not only reduces livestock performance but also increases the risk of erosion. sheep grazing in an area where more than five kilometers away from water sources, due to the prolongation of the march rou...

All four chimpanzee sub-species populations are declining due to multiple factors including human-caused habitat loss. Effective conservation efforts are therefore needed to ensure their long-term survival. Habitat suitability models serve as useful tools for conservation planning by depicting relative environmental suitability in geographic space over time. Previous studies mapping chimpanzee ...
