The ‘I’iwi, also known as the Hawaiian honeycreeper is native to the Hawaiian islands. Once common among the islands, their populations have been declining throughout the islands because of foreign diseases, predators, agricultural and urban development, as well as climate change (‘I’iwi). With the decreasing populations of these birds, the local ecosystems will be greatly…

Trophic cascades occur in nature when predators in a food web alter the behavior of their prey or suppress their number, thereby indirectly affecting the next lower trophic level in a positive way. This theory has been shown to be important in understanding the effects of removing a keystone species from a food web. Many…

The cassowaries are large, flightless ratite birds that are found in the rainforests of Papa New Guinea, Australia, and some of the surrounding islands (Sanft 1975). Weighing up to 85 kg, these birds are second in size only to the ostrich. Native peoples hunted the cassowaries and valued them as livestock; it was reported that…

The Masked bobwhite quail is an extremely rare and fragile subspecies of the more popular and widespread Northern bobwhite. The Masked bobwhite is and has been endangered from the moment it was discovered. These quail are very susceptible to habitat loss. They are native to the desert grasslands of Arizona and Mexico, but have been…

Inappropriate medical waste (MW) management practices have become one of the major concerns in developing countries. The objectives of this study are to appraise the procedures and techniques available in collection and segregation of MW, treatment and recycling processes, disposal practices and compliances with rules and regulations in the Health-care Facilities (HCFs) in Ota, South West…

ECOLOGY In the original Greek “oikos” means, “house”. So ecology is “the study of the house” the place where you live, or the environment which technically includes all those factors, both nonliving and living, that affect an organism. Ecology then is the study of the interactions of organisms in their environment includes both the living…

The biosphere is the part of the Earth in which life exists. It is 20 km thick, from the bottom of the ocean to the lower atmosphere. It consists of three layers: the lithosphere, which is the land on the surface of the Earth; the hydrosphere, which comprises the water on Earth as well as…

Ecology is a branch of science concerned with the interrelationships of organisms and their environment. An ecosystem is a community, along with its nonliving factors, that exist together. Scientifically, a community consists of a collection of creatures that live together in a particular place. The Coming Plague is a novel that outlines how each epidemic…

Explain the difference between Biosphere, Ecosphere and Gaia and reason a instance for following one of these forms for treatments of the Earth Biosphere, Ecosphere and Gaia are used names of the planetary ecosystem. But each planetary ecosystem has its ain or more pregnant separately. The planetary ecosystem is natural rhythms of interdependent beings which…
