Ecological features of environmental factors Kyiv

Experimental and environmental factors affect spurious detection of ecological thresholds.

Threshold detection methods are increasingly popular for assessing nonlinear responses to environmental change, but their statistical performance remains poorly understood. We simulated linear change in stream benthic macroinvertebrate communities and evaluated the performance of commonly used threshold detection methods based on model fitting (piecewise quantile regression [PQR]), data partiti...

Sustainability of environmental management in Iran: An ecological footprint analysis

ABSTRACT- Sustainability and environmental management are the most cited ideas linking the environment and development. The sustainability of natural resources depends upon our paradigm and related approaches to the relationship between society and the environment. Efficient management is a primary task due to the pressure on nature. Ecological footprint analysis has been intro...

Ecological neighborhoods : scaling environmental patterns

In this paper we review, develop, and differentiate among concepts associated with environmental patterning (patch,-division, and heterogeneity), spatial and temporal scales of ecological proaesses (ecological neighborhoods), and responses of organisms to environmental patterning (relative patch size, relative patch duration, ielative patgh isolation" and grain lespoqse), We gencralizc the conc...
