Duck nest survival in the Missouri Coteau of North Dakota: Landscape effects at multiple spatial scales

Article Abstract:

The relationships between habitat variables and duck nest survival on 10-4 Km(super 2) sites selected across a gradient of landscape characteristics in the Missouri Coteau Region of North Dakota are described. Conservation efforts focused on maintaining duck populations should maintain landscapes with abundant grasslands and to account for the influence of configuration using GIS analyses.

Alien plant dynamics following fire in Mediterranean-climate California shrublands

Article Abstract:

Hypothesized factors determining alien dominance were tested with structural equation modeling. Fire history is an important indirect factor as it affects both prefire stand structure and postfire alien seed banks.
