The aim of this study was modelling the spatial distribution ofLilium ledebourii (Baker) Boiss. based on ecological characteristics, in order to predict potential habitats for conservation of a rare plant. Knowledge of the spatial distributions of rare and threatened species and the underlying ecological factors plays an important role in regional conservation assessments and development planni...

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...

In 2013, the World Health Organization (WHO) recognized mycetoma as one of the neglected tropical conditions due to the efforts of the mycetoma consortium. This same consortium formulated knowledge gaps that require further research. One of these gaps was that very few data are available on the epidemiology and transmission cycle of the causative agents. Previous work suggested a soil-borne or ...

Ecological bias is sometimes attributed to confounding by the group variable (ie the variable used to define the ecological groups), or to risk factors associated with the group variable. We show that the group variable need not be a confounder (in the strict epidemiological sense) for ecological bias to occur: effect modification can lead to profound ecological bias, whether or not the group v...

BACKGROUND AND AIM Mediterranean Sea, Egypt is an economically important marine environment. During the last decades there has been extensive increase in the levels of urbanization and industrialization along its coastal area. Therefore, the present work attempts to determine the status of heavy metals distribution in sediment samples, and their ecological risk assessment in the studied area. ...

Despite many studies showing that landscape corridors increase dispersal and species richness for disparate taxa, concerns persist that corridors can have unintended negative effects. In particular, some of the same mechanisms that underlie positive effects of corridors on species of conservation interest may also increase the spread and impact of antagonistic species (e.g., predators and patho...

street dusts are suspended particle matters in the air from different natural and anthropogenic sources that may fall out because of their size and density. forty nine street dust samples were collected from some main streets of eastern and southern parts of tehran. one other sample was also collected from iran university of science and technology central campus for comparisons during summer un...

Renewable energy will potentially make an important contribution towards the dual aims of meeting carbon emission reduction targets and future energy demand. However, some technologies have considerable potential to impact on the biodiversity of the environments in which they are placed. In this study, an assessment was undertaken of the realistic deployment potential of a range of renewable en...
