Finer‐scale habitat predicts nest survival in grassland birds more than management and landscape: A multi‐scale perspective

Autor: Justin J. Shew, Donald W. Sparling, Clayton K. Nielsen

Publikováno v: Journal of Applied Ecology. 56:929-945

Birds may respond to habitat at multiple scales, ranging from microhabitat structure to landscape composition. North American grassland bird distributions predominantly reside on private lands, and populations have been consistently declining. Many o

Seasonal Patterns of Intraguild Predation and Size Variation among Larval Salamanders in Ephemeral Ponds

Autor: Donald W. Sparling, Cy L. Mott

Publikováno v: Journal of Herpetology. 50:416-422

Predation among potential competitors, or intraguild predation (IGP), is dependent on size disparities between competing predators and prey and strongly influences the ecology of larval amphibians in ephemeral ponds. Although intraguild prey are hypo

A Comparison of Three Macroinvertebrate Sampling Devices for Use in Conducting Rapid-Assessment Procedures of Delmarva Peninsula Wetlands

Autor: Donald W. Sparling, Kerry Tebbs, T. Peter Lowe

Publikováno v: Northeastern Naturalist. 23:321-338

Three types of macroinvertebrate collecting devices, Gerking box traps, D-shaped sweep nets, and activity traps, have commonly been used to sample macroinvertebrates when conducting rapid biological assessments of North American wetlands. We compared
