Bacillus thuringiensis Bacillus thuringiensis is a universal‚ gram-positive‚ vegetative‚ spore-forming bacterium that is rod shaped and varies between 2–5 µm long and about 1.0 µm wide . Bt consists large rods with slightly curved ends and forms a parasporal crystal during the stationary phase of its growth cycle . Occurring in pairs or short chains‚ Bt is also motile with peritrichous flagella and non-caspulated . Bt belongs to the family of bacteria‚ Bacillus cerus (B. cerus)‚ which produces

Coexistence is the state in which two or more things exist together usually temporarily and with or without mutual relationship. A wide range of animals practise coexistence either between allopatric or sympatric organisms‚ these organisms includes Bees‚ Lizards‚ Birds‚ Ants etc which could be either through character displacement or resource partitioning . Character displacement is the phenomenon where differences among similar species whose distributions overlap geographically are accentuated in

Factors leading to Biodiversity Loss: Biodiversity is affected by multiple drivers and pressures that modify its ability to provide ecosystem services to people. The interaction of multiple drivers‚ including demographic‚ economic‚ socio-political‚ scientific and technological ones‚ as discussed earlier‚ is known to increase pressures on biodiversity‚ leading to further decline‚ degradation and loss. However‚ the mechanisms associated with such loss require further research. The direct mechanisms

Causes of recent declines in biodiversity The major causes of biodiversity decline are land use changes‚ pollution‚ changes in atmospheric CO2 concentrations‚ changes in the nitrogen cycle and acid rain‚ climate alterations‚ and the introduction of exotic species‚ all coincident to human population growth. For rainforests‚ the primary factor is land conversion. Climate will probably change least in tropical regions‚ and nitrogen problems are not as important because growth in rainforests is usually

Tropical Rain Forest The Tropical Rainforest is a very diverse Biome. Being diverse means that many different types of animals‚ plants and climates. It is in my personal opinion the greatest biome that exists in today’s world. This biome is home to 50% of the plants and animals on the Earth. The Tropical Rainforest is present on just 2% of the world. The Rainforest is home to many different species of animals. Some of them include butterflies‚ beetles‚ spiders‚ ticks‚ worms‚ snakes‚ lizards‚ jaguars
