Species redundancy: a redundant concept?

Article Abstract:

The concept of species redundancy implies that the loss of some species may not be as critical to ecological communities as the loss of others. The concept originated from the idea that species can be grouped according to their ecological function and effect on other species. These species can also be classified based on similar competitive abilities, a significant aspect of species conservation. Species redundancy is a complex and entails collecting a large body of information for each species, and the limited knowledge about ecology suggests the importance of preserving all species.

Environmental rugosity, body size and access to food: a test of the size-grain hypothesis in tropical litter ants

Article Abstract:

The ability of tropical litter ant species with different body sizes to access food baits in landscapes with different levels of rugosity and food exposure is investigated. The assumption of the size-grain hypothesis (SGH) is tested.
