Human society strongly depends on vital functions and services of natural ecosystems (IPBES, 2019; Zedler & Kercher, 2005). These include food production, fisheries, recreation, drinking water supply, energy generation carbon storage (Clarkson et al., 2013; Consequently, do not only have intrinsic cultural values but are increasingly requested to provide multiple simultaneously, including econo...

The ease of application and effectiveness of a multimetric benthic index of biotic integrity (B-IBI) was evaluated for use as an ecological integrity monitoring tool in coastal National Parks of Canada. The B-IBI was developed in three phases: 1) analysis of land use impacts to select study watersheds along a gradient of disturbance; 2) collection and identification of benthic macroinvertebrate...

It has been 22 years since William Jordan III and the University of Wisconsin Arboretum published the first issue of Restoration and Management Notes, 16 years since the founding of the Society for Ecological Restoration (SER), and 10 years since SER published the first issue of its flagship journal, Restoration Ecology. In this short time, restoration ecology has become a leader in North Ameri...

In this paper we will continue the study of p-closed spaces. This class of spaces is strictly placed between the class of strongly compact spaces and the class of quasi-Hclosed spaces. We will provide new characterizations of p-closed spaces and investigate their relationships with some other classes of topological spaces.

What should and should not be considered an affordance is still an open issue. At the 2002 North American meeting of the International Society for Ecological Psychology, a symposium was held concerning this topic. The articles in this special issue are expanded versions of the papers presented at that symposium. To set the stage for those discussions, this article presents an analysis of the ev...

The challenges of managing natural resources of protected areas not only come from the inside of the protected boundaries, but also from the surrounding territories because most of protected lands are open systems that face threats from adjacent areas. The lands of such open systems alter water quality and flow regimes, increase the likelihood of invasive plant and animal range expansions, redu...

Abstract Story segmentation is an important problem in multimedia indexing and retrieval and includes detection of commercials as one of its component problems. Commercials appear regularly in television data and are usually treated as noise. Hence, filtering of commercials is an important task. This paper presents a system that detects and filters commercials from broadcast news data. While pr...

Benthic macroinvertebrates were collected from streams located in an urban area from regions featuring different environmental conditions. Physicochemical variables and land use types pertaining to sampling sites were analyzed concurrently. Multivariate analyses (cluster analysis and non-metric multidimensional scaling) and rank-abundance diagrams were used to characterize community patterns to...

From California sequoia, to Australian eucalyptus, to the outstanding diversity of Amazonian forests, trees are fundamental to many processes in ecology and evolution. Trees define the communities that they inhabit, are host to a multiplicity of other organisms and can determine the ecological dynamics of other plants and animals. Trees are also at the heart of major patterns of biodiversity su...

evidence supports the involvement of nitric oxide (no) in a varity of male reproductive processes such as spermatogenesis, spermiogenesis, sperm motion, sperm metabolism and sperm capacitation. however, low concentration of no is essential in biology and physiology of spermatozoa, but high amounts of no is toxic and has negative effects on sperm functions. on the other hand, it is established t...
