Craig M. Thompson, J. Andrew Royle, James D. Garner
2012, Journal of Wildlife Management (76) 863-871
Wildlife management often hinges upon an accurate assessment of population density. Although undeniably useful, many of the traditional approaches to density estimation such as visual counts, livetrapping, or mark–recapture suffer from a suite of methodological and analytical weaknesses. Rare, secretive, or highly mobile species exacerbate these problems through the reality...
Feedbacks between inundation, root production, and shoot growth in a rapidly submerging brackish marsh
Matthew L. Kirwan, Glenn R. Guntenspergen
2012, Journal of Ecology (100) 764-770
1. Ecogeomorphic feedbacks between mineral sediment deposition and above-ground plant growth are thought to have dominated the evolution of many coastal ecosystems and landforms. However, land-use-related reductions in sediment delivery rates to estuaries world-wide suggest that these above-ground feedbacks may not apply in some of the world's most vulnerable coastal...
