Critical Habitat has become an increasingly important concept used by the finance sector and businesses to identify areas of high biodiversity value. The International Finance Corporation (IFC) defines Critical Habitat in their highly influential Performance Standard 6 (PS6), requiring projects in Critical Habitat to achieve a net gain of biodiversity. Here we present a global screening layer o...
The importance of sensory information for the guidance of animal behavior is reflected by a fascinating wealth of sensory organs. These exhibit an enormous variety due to different evolutionary potentials and needs of individual species. All sensory organs and their neuronal pathways have to be tuned to the reception and perception of the biologically relevant stimulus patterns as they occur in...
Ethiopia harbours several relict populations of African wild dogs Lycaon pictus, but most data is anecdotal. Wild dogs are known to occur atypically in the montane wet forest of Harenna in the southern slopes of Bale Mountains National Park, southeastern Ethiopia. A questionnaire-survey of 90 Harenna forest residents investigated the local people’s knowledge and attitudes to wild dogs. Wild dog...
Demand for information that can be used to manage loggerhead shrikes has recently increased because of concern over declining populations and loss of open, non-forested habitat. A previously-developed habitat model was modified to predict shrike habitat quality on Fort Riley Military Reservation (FRMR) in Kansas. Shrike habitat suitability indices were calculated based on the amount of potentia...
Habitat loss threatens large mammals worldwide, and their survival will depend on habitat in human-dominated landscapes. Conservation planners thus face the challenge to identify areas of least conflict with land use, yet broadscale species distribution models rarely incorporate real landscape patterns nor do they identify potential conservation conflicts. An excellent example of such conservat...
Astracantha gossypina (Fisch.) is one of the most important rangeland plants in the northeastern region of Iran and has a great role in soil conservation and the economy of ranchers. unreasonable uses and management of desire plant species usually led to species loss and the replacement of endemic and specialist species by invasive endemic or exotic species. This study was conducted to determin...
Hyrcanian forests are one of the most valuable forests in the world, dating from about 25 to 50 million years old. Climate variation, unique plant and animal species accompany with habitat diversity have made these forests one of the most unique ecosystems on Earth and worthy of being listed on the UNESCOchr('39')s World Heritage List. Therefore, the main purpose of this study is to use both De...
Gray wolf populations have been rebounding in the Great Lakes region, after being nearly extirpated from the conterminous United States. Breeding populations of wolves have established in the Upper Peninsula of Michigan but have not yet become widely established in the Lower Peninsula (LP) of Michigan, despite several sightings of wolves in the LP since 2004. The objective of this analysis was ...
the aim of this study was to investigate the effect of reforestation on physical and chemical soil properties particularly soil carbon storage in the berenjastanak forest. forestations were including acer velotinum boiss., fraxinus excelsior l., populus nigra l. and pinus brutia ten. a witness forest with mixed species was selected as region potential. four soil profiles were drilled in each fo...
The Baluchistan Black Bear (BBB), a critically endangered subspecies (CR), is distributed in the southeastern Iran. Modelling of landscape connectivity of the BBBs among habitat patches can be insightful for the conservation managers working in Iran. Our study was designed to identify the potential corridors among 31 habitat patches of the BBBs in Iran using the circuit theory method. Habitat s...
