Exotic Bird Invasion Into Forests of Hawaii: Demography, Competition, and Seed Dispersal
… did have a strong and conspicuous impact on native and non-native plants. In an ecosystem where most native frugivores are extinct, introduced birds dispersed all common native plants in these forest sites but non-native plants were infrequently eaten and dispersed. Furthermore, introduced …

Native Forb Establishment in Tall Fescue-dominated Cattle Pastures
… gaps remain in the consistent establishment of native forbs in intensively managed agricultural areas. We evaluated factors that influence native forb establishment during seed-based enrichment planting of tall fescue-dominated cattle pastures in two separate experiments: one testing a range of …

Granivory and Granivores in Native Grasslands and Agropyron Cristatum Stands in the Northern Great Plains
… seed preferences, and ant communities in paired native grasslands and A. cristatum stands. I examined temporal variation in vegetation factors that influence granivory rates. Finally, I determined the relationship between seed size and vertebrate granivore preferences in herbaceous and woody …

A tale of two grasses: Seed production has small & potentially positive effects on seed & seedling traits of squirreltail grasses, but Thurber’s needlegrass resists farming
Native seed is increasingly farmed to meet the growing demands of seed-basedrestoration. One concern is that farm environments are expected to alter wild collections, leading to phenotypic changes that may hinder establishment. Focusing on two native perennial grasses in the western United States, …

THE FEASIBILITY OF CHAPARRAL RESTORATION ON TYPE-CONVERTED SLOPES
… disturbances have caused type-conversion of native chaparral to non-native annual grasslands. Competition with non-native annual grasses hinders shrub establishment, presenting challenges in restoration. This study examined the feasibility of chaparral restoration in a Mediterranean-type …
