Studies of river suspended sediment typically focus on mass loads with little attention devoted to sediment properties such as particle size distribution (PSD) or light attenuation. However, environmental behaviour and ecological effects of suspended sediment vary greatly with particle properties. Visual clarity is a particularly important attribute of waters that is strongly affected by particle properties. We studied the rel...

Ecology Letters (2012) Abstract Epidemiology in host meta‐populations depends on parasite ability to disperse between, establish and persist in distinct sub‐populations of hosts. We studied the genetic factors determining the short‐term establishment, and long‐term maintenance, of pathogens introduced by infected hosts (i.e. carriers) into recipient populations. We used experimental populations of the freshwater ciliate Parame...
