Biodiversity in model ecosystems

Biodiversity in model ecosystems, I: coexistence conditions for competing species.

This is the first of two papers where we discuss the limits imposed by competition to the biodiversity of species communities. In this first paper, we study the coexistence of competing species at the fixed point of population dynamic equations. For many simple models, this imposes a limit on the width of the productivity distribution, which is more severe the more diverse the ecosystem is (199...

Ice Ecosystems and Biodiversity

Biodiversity and ecosystems

Biologists devised the word biodiversity to allow us to talk about the totality of life on Earth, encompassing everything from the level of DNA and genes, through to individuals, species, and whole ecosystems. Reducing global biodiversity loss in the face of unprecedented population extirpation and species extinction has become a fundamental goal for conservation, and the subject of an array of...

Crab biodiversity under different management schemes of mangrove ecosystems

Reforestation is one of the Philippines’ government efforts to restore and rehabilitate degraded mangrove ecosystems. Although there is recovery of the ecosystem in terms of vegetation, the recovery of closely-linked faunal species in terms of community structure is still understudied. This research investigates the community structure of mangrove crabs under two different management schemes: p...

Hierarchical scaling of biodiversity in lagoon ecosystems

Lagoons are habitat islands in the coastal landscapes characterised by both among ecosystems 1 heterogeneity, due to different terrestrial-freshwater, freshwater-marine interfaces, and within ecosystem heterogeneity, due patchy spatial and temporal distribution of biotic and abiotic
