used as a substitute for other species whose attributes are difficult to define and measure. There are different types of indicator species based on conservation goals. Some common indicator type :are health indicators‚ population indicators and biodiversity indicators (Caro and O’Doherty 1999). Health indicators are used to measure changes in the environment such as habitat change (Caro and O’Doherty 1999). Population indicators are used to compare and monitor changes in other species (Caro and O’Doherty

Threats to Marine Biodiversity Biodiversity’ is the name for the variety of all biological life. This includes plants‚ animals‚ fungi and microorganisms‚ the genes they contain and the ecosystems they live in. ’Marine biodiversity’ refers to this variety of life in coastal and ocean environments. Biodiversity loss has become one of the greatest environmental concerns of the last century‚ owing to increasing pressure on the environment by humans combined with the realisation that our activities

and theories of anthropology while applying them to a virtual world. The title of the book is a play on Margret Mead’s classic work Coming of Age in Samoa (1928). Second Life is a platform created by Linden Lab. Their aim was to create a “revolutionary new form of shared 3D experience” (Linden Labs). Coming of Age in Second Life is divided into three parts and nine chapters. The first part‚ titled “Setting the Virtual Stage” contains three background chapters that set the context of the research.

Non climate threats such as habitat loss‚ habitat fragmentation‚ and invasive species and air and water pollution Fragmentation: often due to man (dams‚ roads‚ and general development) Elements of biodiversity: Species‚ ecosystems & landscapes Mammals from bats to bears Bats got the white nose fungus which caused the bats to die and the insect population flourished because the bats main job

The natural world or nature represents the physical world and the living elements found within it. In its broadest sense‚ nature entails all the living and inanimate things that exist within the physical world. All the elements of the natural world‚ whether living or inanimate‚ significantly depend on each other. Of all the living things‚ man crucially depends on the elements of nature for his survival. On the same account‚ we have the responsibility to ensure that the natural world remains intact

one of 12 mega-diversity countries possessing a rich means of all living organisms when biodiversity is viewed as a whole. The greater the multi-diversity of species‚ greater is the contribution to the biodiversity. India’s rich biological diversity - its immense range of ecosystems‚ species and genetic forms is by virtue of its tropical location‚ climate and physical features. India’s fabulous biodiversity is estimated to be over 45‚000 plant species representing about seven percent of the world’s

As habitat fragmentation in southern California split land‚ the integrity of the land changes. Habitat fragments that each has a decrease in area will have an increase in the total perimeter distance collectively (Morrison et al.‚ 2006). This increased area around the habitat exposes more of the internal habitat to the elements‚ reduces the habitat buffer‚ and in turn creates less optimal habitat for species in the fragment (Morrison et al.‚ 2006). This process‚ called edge effect‚ decreases the
