Glossary Cover type A term used by the geographers for a type of mapped feature (e.g., forest, freshwater, or grassland). The dominant natural cover type in a landscape is often used to approximate habitat. Fragmentation per se The breaking apart of habitat while keeping habitat amount constant. Habitat The place where an organism normally lives. Habitat fragmentation The breaking apart of habi...

the aim of this study was to develop a methodology to identify suitable habitat of the eurasian nuthatch (sitta europea) at kheyrood forest, northern alborz, iran. this study was carried out during spring to summer 2008. with attention to the area and topographic condition of kheyrood forest, patom, namkhane, gorazbon, cheler and baharbon were selected as data collecting series. the present stu...

Habitat suitability models have been extensively used by conservation planners to estimate the likelihood of occurrence and abundance of threatened wildlife species in terrestrial ecosystems, but they have been rarely applied to aquatic environment. In this study a GIS-based habitat suitability (HS) model has been developed to identify suitable sites for Manila clam (Tapes philippinarum) farmin...

Many species live in ecosystems where resources are distributed patchily within the landscape. Furthermore, an ever-increasing number of species are forced to live in fragmented landscapes due to the destruction of their habitat, generally caused by anthropogenic disturbance. These metapopulations are consequently drawing much attention in both the theoretical and applied ecology literature (Le...

The construction of artificial shelter forests (ASFs) has resulted in substantial ecological, economic, and societal benefits to the Chinese Loess Plateau (CLP). However, health ASFs are being increasingly threatened by formation low-efficiency (LEASFs). In this study, LEASFs systematically analyzed terms their status, mechanisms, developmental obstacles. key restoration techniques schemes were...

The term critical habitat is used to describe the subset of habitat that is essential to the survival and recovery of species. Some countries legally require that critical habitat of listed threatened and endangered species be identified and protected. However, there is little evidence to suggest that the identification of critical habitat has had much impact on species recovery. We hypothesize...

I challenge (1) the assumption that habitat patches are natural units of measurement for species richness, and (2) the assumption of distinct effects of habitat patch size and isolation on species richness. I propose a simpler view of the relationship between habitat distribution and species richness, the ‘habitat amount hypothesis’, and I suggest ways of testing it. The habitat amount hypothes...

Land acquisition along the stream for angler access, streambank protection and habitat improvement began in the early 1960s. In 1985, a master plan for the stream was approved and these lands were consolidated into the Duncan Creek Fishery Area. The fishery area covers Duncan Creek from its headwaters downstream to 190 Avenue, immediately above Lake Como. Approximately 7.8 miles of the stream t...
