The effects of channelization can be exacerbated by local geology and land-use...
The ovenbird (Seiurus aurocapilla) as a model for testing food-value theory
Henry M. Streby, Sean M. Peterson, Brian Scholtens, Adrian P. Monroe, David E. Andersen
2013, The American Midland Naturalist (169) 214-220
Food-value theory states that territorial animals space themselves such that each territory contains adequate food for rearing young. The ovenbird (Seiurus aurocapilla) is often cited as a species for which this hypothesis is supported because ovenbird territory size is inversely related to ground-invertebrate abundance within territories. However, little is known...
