Prey availability and flow conditions drive changes in barramundi abundance

By Mischa Turschwell Predator-prey interactions between fishes are important ecological processes that help maintain healthy populations and ecosystems. But often we don’t know if predators control prey numbers (top-down control) or if the number of prey available controls predator numbers (bottom-up control). We also don’t know how these interactions might change if environmental conditions like […]

The Amazon is under threat, but our new study gives hope to improving conservation planning and management

Author: Dr Vanessa  Reis, Wetland ecosystems are important hotspots of biodiversity in the Amazon River Basin, but they’re under threat from human activity.  These ecosystems rely on the maintenance of the annual river flood pulse that drives inundation across the major wetlands of the Amazon. Infrastructure project proposals such as dams have increased in response to higher […]
