Biology Notes: Threats to biodiversity in MA 1. Climate change: temp‚ sea levels‚ precipitation 2. 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

Biodiversity and Conservation Biology Chapter 11 Review Sheet I. Central Case: Saving the Siberian Tiger A. Up until the past 200 years‚ tigers roamed widely across the Asian continent from Turkey to northeast Russia to Indonesia. B. Of the tigers that still survive in small pockets of their former range‚ those in the subspecies known as the Siberian tiger are the largest cats in the world. C. For thousands of years‚ the Siberian tiger coexisted with the native people of what is today

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

A Balanced Ecosystem - An Aquarium The term ecosystem describes both the living and non-living components of an area that interact with one another. All the components are inter-dependant in some way with each other. An ecosystem may be aquatic or terrestrial. In an aquatic ecosystem rocks are needed for shelter and plants provide oxygen for fish. An ecosystem is balanced when the natural animals and plants and non-living components are in harmony- i.e. there is nothing to disturb the balance.

Bio Diversity: A Major Concern of Our Eco System The variety of life on Earth‚ its biological diversity is commonly referred to as biodiversity. The number of species of plants‚ animals‚ and microorganisms‚ the enormous diversity of genes in these species‚ the different ecosystems on the planet‚ such as deserts‚ rainforests and coral reefs are all part of a biologically diverse Earth. Appropriate conservation and sustainable development strategies attempt to recognize this as being integral to any

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

Forests in Their Age‚ Makeup‚ and Origins A. 2 Major Types of Natural Forests 1. Old-growth/ Primary -uncut/ regenerated forest that has not been seriously disturbed by human activities/ natural disasters for 200 years or more - reservoirs of biodiversity (provide ecological niches for a variety of wildlife species) 2. Second- growth - stand of trees resulting from secondary ecological succession B. Tree Plantation/ Tree Farm/ Commercial Forest -managed forest containing one or two species
