The role of animals in an arid ecosystem: snails and isopods as controllers of soil formation, erosion and desalinization

The AA. use the snails and isopods as case studies to examine: 1) the relationships between activities of animals and abiotic resource dynamics. Here the concept of ecological flow chains is used to explicitly interrelate the flows of energy
and materials controlled by biotic and abiotic factors; 2) the relationship between animal density to the spatial and temporal dynamics of soil formation.

How does floodplain width affect floodplain river ecology? A preliminary exploration using simulations

The AA. explore this question with a simple simulation model of the dynamics of a food web in a river with seasonally fluctuating discharge. Components of this river food web spread across a floodplain when it is inundated at high water
of the channel. This model assumes extremely simplified spatial and dynamic properties of both physical and biological components of the ecosystem.
