Foodweb interactions, such as competition for limiting resources, are inherently
non-linear. Consequently, they can give rise to chaotic, or undeterminable,
population dynamics. Population dynamics are not always undeterminable,
however, sometimes...

I used a conceptual model proposed by Schlosser (1987) to compare channelized
and unchannelized reaches of the South Sulphur River, Texas. This model suggests that
fish assemblage structure can be predicted based on the level of habitat heteroge...
