Biodiversity Loss and Ecological Network Structure
The world is currently experiencing exceptionally high rates of species extinctions, largely as as result of human activity (Lawton and May 1996). Currently, most conservation research on habitat destruction focuses on the species as the unit of study, looking at either the impact of habitat destruction on individual species, or collections of species from particular habitats. There is, however...
متن کاملCauses of Biodiversity Loss: a Human Ecological Analysis
Important biological causes of the loss of biological diversity include the loss of habitats, the introduction of exotic species, over-harvesting of biodiversity resources, and homogenisation of species in agriculture. The common factor of all these elements is that they are human-driven. This paper analyzes the economic and social root causes behind biodiversity loss. The analysis is based on ...

We study the management of a natural resource that supports ecosystems as well as human needs. The reduction in the resource base introduces a threat of occurrence of catastrophic ecological events, such as the sudden collapse of the natural habitat, that lead to severe loss of biodiversity. The event occurrence conditions involve uncertainty of various types, and the distinction among these ty...
متن کاملUrban expansion as a driver of biodiversity loss: Integrating biodiversity in urban planning in African context
Africa has high biodiversity and is rapidly urbanizing. However, there is limited understanding of how urban expansion in Africa is likely to affect its habitats and biodiversity. Little urban ecological research has been done in Africa. This study needs to think ahead as Africa move into the “urban age” it is critical to inform the public on the importance of urban environment...
متن کاملThe ecological consequences of megafaunal loss: giant tortoises and wetland biodiversity
The giant tortoises of the Galápagos have become greatly depleted since European discovery of the islands in the 16th Century, with populations declining from an estimated 250 000 to between 8000 and 14 000 in the 1970s. Successful tortoise conservation efforts have focused on species recovery, but ecosystem conservation and restoration requires a better understanding of the wider ecological co...
