4)process of planning and creating a nature reserve in a way that effectively accomplishes the goal of the reserve. a single large or several small (SLOSS) reserves were a superior means of conserving biodiversity in a fragmented habitat.A single large reserve was preferable to several smaller reserves whose total areas were equal to the larger.Since species richness increases with habitat area, a larger block of habitat would support more species than any of the smaller blocks 5)Eutrophication ...more precisely hypertrophication, is the depletion of oxygen in a water body, which kills aquatic animals. It is a response to the addition of excess nutrients Eutrophication arises from the oversupply of nutrients, which leads to over growth of plants and algae. After such organisms die, the bacterial degradation of their biomass consumes the oxygen in the water, thereby creating the state of hypoxia.
