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...

Few ecological studies have explored landscape suitability using the gradient concept of structure for wildlife species. Identification conditions influencing ecology endangered species allows development more robust recovery strategies. Our objectives were to (i) identify range metrics (i.e., mean patch area; and edge densities; percent land cover; shape, aggregation, largest indices) associat...

The potential generality of local processes in determining spatial patterns of molluscan assemblages in turfs of Corallina officinalis is evaluated by testing hypotheses about consistency in ecological pattern on shores in Australia, Ireland and Chile. Identical sampling protocols on 2 shores in each country were used to test 2 specific hypotheses: (1) that molluscan assemblages vary significan...

the purpose of this work was to study the effect of various permeation enhancers on the permeation of salbutamol sulphate (ss) buccal patches through buccal mucosa in order to improve the bioavailability by avoiding the first pass metabolism in the liver and possibly in the gut wall and also achieve a better therapeutic effect. the influence of various permeation enhancers, such as dimethyl sul...

Considering that the development of urbanization cannot be separated from application landscape pattern evolution, in order to improve level ecocity, a modeling analysis ecological urban evolution based on multisource remote sensing data is proposed. Taking ecotype city as research object, images are screened by using and nonremote basic data. CA-Markov model constructed analyzed. The experimen...

We consider ecological difference equations of the form xt+1 = x i tAi(xt), where x i t is a vector of densities corresponding to the subpopulations of species i (e.g., subpopulations of different ages or living in different patches), xt = (xt , x 2 t , . . . , x m t ) is the state of the entire community, and Ai(xt) are matrices determining the update rule for species i. These equations are pe...
