An ecosystem is a complex adaptive system with its diverse components continually interacting and thus giving rise to emergent properties that determine the trajectory of time evolution of the ecosystem. The evolutionary dynamics of species of grassland and woodland vegetation in the savannah ecosystem set in a protected area in the Central Indian Plateau were studied in this paper. These components compete with each other through inter- as well as intra-specific coupling constants to obtain resources for growth. It was found that in the absence of any external grazing pressure on the toy model, there would not exist any equilibrium point attractor for the system to settle down sufficiently after a long time. The system may thus continue to evolve along its initial trajectory, thereby retaining its initial structure and functions.

    Labrador, Canada is the last relatively undeveloped landmass of Boreal and subarctic Canada. Its land area is over 288,000 km2, with less than 1% developed, and a human population of below 30,000. Labrador is greater than 60% forest- and woodland-covered and over 30% tundra, soil and rock...

    Many studies predict effects of future climate scenarios on species distributions, but few predict impacts on landscapes or ecological communities, the scales most relevant to conservation management. We combined expert knowledge with community-level spatial modelling (using artificial neural...

    A "biome" is a large natural area that is the home to a certain type of plant. The animals, climate, soil, and even the amount of water in the region, also help distinguish a biome. There are more than 30 kinds of biomes in the world. But the following types cover most of Earth's surface. ...

    Bioprospecting has frequently been cited as a sustainable use of biodiversity. Nevertheless, the level of bioprospecting in biodiversity-rich tropical regions falls below its potential, with the result that bioprospecting has produced only limited economic benefits. We present a bioprospecting...
