—Microhabitat selection is critical to thermoregulation in ectotherms, particularly in small-bodied organisms for which low thermal inertia can impose rapid acquisition of thermal equilibrium with the environment. Although thermal microhabitat selection is often included in studies of niche partitioning among lizard species these investigations typically address only adult thermoregulation and,...

this study sought to develop a decision support system (dss) for assisting range managers to detect range condition and make informed decisions about feridan county rangelands. all plant species frequencies were measured in 31 range sites with various grazing histories using step point method. four hundred points along four perpendiculars 30 meters transects were measured in each site and grazi...

Purpose The resourcing of policing activity is characterised by a level of complexity, particularly where evaluating alternative policy options is concerned. In this paper, a case study using multimethodological modelling to compare alterative policy choice in a group context is outlined with respect to response-patrol officer deployment within a UK police force. Design/methodology/approach The...

Evolution of sexual dimorphism in ecologically relevant traits, for example, via resource competition between the sexes, is traditionally envisioned to stall the progress of adaptive radiation. An alternative view is that evolution of ecological sexual dimorphism could in fact play an important positive role by facilitating sex-specific adaptation. How competition-driven disruptive selection, e...

The aim of the present paper is to formulate a general integrated aggregate dynamic model for sustainable development, that will be both simple in structure and able to deal with the main objectives, processes and constraints applying to sustainable development in closed economic-ecological systems. General characteristics of models to be used for sustainable development are discussed. It turns...

Article history: Received 3 August 2015 Received in revised form 25 July 2016 Accepted 23 September 2016 Available online xxxx Empirical research has identified various institutions that improve resource longevity by supporting individual resource conservation. However, themechanisms bywhich these institutions emerge have not been established. We speculate that economic institutionswhich suppor...

Although there are remarkable differences in drivers’ behavior as well as vehicles characteristics, road capacity estimationmethods in developing countries are same as developed ones. So, the discrepancy between the theoretical andpractical values of capacity is inevitable. Although, capacity estimation methods can be classified based on numerousparameters, in developing count...

Context: Ecological speciation is commonly inferred with evidence of the parallel evolution of pre-mating isolation: individuals from populations in similar environments show higher mating success in laboratory experiments than do individuals from different environments. Critically, this should hold even for mating crosses among populations that are from different locations that represent indep...
