The dominance of invasive species is often assumed to reflect their competitive superiority over displaced native species. However, invasive species may be abundant because of their greater tolerance to anthropogenic impacts accompanying th...

Grasses using the C(4) photosynthetic pathway dominate today's savanna ecosystems and account for approximately 20% of terrestrial carbon fixation. However, this dominant status was reached only recently, during a period of C(4) grassland e...
Plant functional types do not predict biomass responses to removal and fertilization in Alaskan tussock tundra [0.03%]

M Syndonia Bret-Harte et al.
Plant communities in natural ecosystems are changing and species are being lost due to anthropogenic impacts including global warming and increasing nitrogen (N) deposition. We removed dominant species, combinations of species and entire fu...
Virus infection and grazing exert counteracting influences on survivorship of native bunchgrass seedlings competing with invasive exotics [0.03%]
病毒侵染和捕食对本土丛生草种子竞争入侵植物的影响不容忽视

Cm Malmstrom et al.
Invasive annual grasses introduced by European settlers have largely displaced native grassland vegetation in California and now form dense stands that constrain the establishment of native perennial bunchgrass seedlings. Bunchgrass seedlin...
