Influence of dreissenid mussels on catchability of benthic fishes in bottom trawls
Patrick M. Kocovsky, Martin A. Stapanian
2011, Transactions of the American Fisheries Society (140) 1565-1573
Inferring trends in true abundance of fish populations from catch per unit effort data requires either the knowledge of capture probability or the assumption that it is constant, both of which are unlikely contingencies. We developed and validated an index of catchability (a proxy measure for capture probability) from a...

Decomposition of heterogeneous organic matterand its long-term stabilization in soils
Carlos A. Sierra, Mark E. Harmon, Steven S. Perakis
2011, Ecological Monographs (81) 619-634
Soil organic matter is a complex mixture of material with heterogeneous biological, physical, and chemical properties. Decomposition models represent this heterogeneity either as a set of discrete pools with different residence times or as a continuum of qualities. It is unclear though, whether these two different approaches yield comparable predictions...
