Human activities on floodplains have severely disrupted the regeneration of foundation
riparian shrub and tree species of the Salicaceae family (Populus and Salix spp.) throughout …

A systematic review focused by plant on non-target impacts from agents deliberately
introduced for the biological control of weeds found significant non-target impacts to be rare …

Generalists rarely are considered for classical biocontrol because their broad feeding habits
are expected to make non-target impacts inevitable. This assumes an increase in overall …

Hydrological and bioclimatic processes that lead to drought may stress plants and wildlife,
restructure plant community type and architecture, increase monotypic stands and bare …

Declines in riparian ecosystem greenness and water use have been observed in the delta of
the Lower Colorado River (LCR) since 2000. The purpose of our case study was to measure …

We measured the rate of dispersal of saltcedar leaf beetles (Diorhabda carinulata), a
defoliating insect released on western rivers to control saltcedar shrubs (Tamarix spp.), on a …

Management actions to protect endangered species and conserve ecosystem function may
not always be in precise alignment. Efforts to recover the California Ridgway's Rail (Rallus …

Invasive plants can have dramatic effects on natural ecosystems. It is unclear, though,
whether these will have a positive or negative effect on animal species' behavior and …

In prehistoric times, the Santa Cruz River in what is now southern Arizona saw many ebbs,
flows, and floods. It flowed on the surface, meandered across the floodplain, and …

Plant community responses to biocontrol of invasive plants are understudied, despite the
strong influence of the composition of replacement vegetation on ecosystem functions and …
