In the present study, some ecological factors were studied for Amphipoda at different depths. The Shannon, Margalef, and Hill indices were used to determine the species diversity, richness and evenness, respectively. In addition, the association and niche overlap values were estimated. Indices of species richness and diversity were highest at 50 and 100m depths, respectively. The or...

The purpose of ecological niche modelling is to obtain a probabilistic species distribution based on species localization and environmental data. The problem is highly complex from the architectural viewpoint because its requirements include different distributed, interoperable and integration issues. Monolithic solutions were proposed and implemented but they were not able to achieve all requi...
geographic information system (gis) and analytical hierarchy process (ahp) were applied to ecological zoning of current agricultural lands in gorgan for sunflower cultivation. for this purpose, agro-ecological requirements of sunflower firstly, identified according to scientific resources. rating and thematic requirement maps were then provided. studied environmental-components were: average, m...
Understanding microbial nutritional requirements is a key challenge in microbiology. Here we leverage the recent availability of thousands of automatically generated genome-scale metabolic models to develop a predictor of microbial minimal medium requirements, which we apply to thousands of species to study the relationship between their nutritional requirements and their ecological and genomic...
Traditionally, the goal of systematics has been to produce classifications that are both strongly supported and biologically meaningful. In recent years several authors have advocated complementing phylogenetic analyses with measures of another form of evolutionary change, ecological divergence. These analyses frequently rely on ecological niche models to determine if species have comparable en...
A representational approach to ecological psychology is presented. This paper identifies a computational-level commonality in ecological psychology research related to passability of apertures. It is argued that a cognitive mechanism capable of comparing the geometric properties of an environment and the geometric properties of the agent can be used to support judgments for action in space.
An alternative view of presence is introduced based on existential philosophy and ecological psychology. This view favors a Heideggerian/Gibsonian metaphysic over the more conventional rationalistic orientation. In this alternative view, notions of subjective presence and objective presence no longer exist. Presence is instead tied to one’s successfully supported action in the environment, this...
