Role of Fire in the Germination Ecology of Fountain Grass (Pennisetum setaceum), an Invasive African Bunchgrass in Hawai‘i
Field and laboratory studies were carried out to test factors expected to be relevant for the germination of fountain grass: (1) light; (2) emergence of fountain grass seedlings from depths of 0, 2.5, and 5 cm; (3) fire passing over exposed and buried seeds; (4) laboratory heat treatment mimicking exposure to grass fire. Both fire in the field and heat applied in the laboratory killed fountain ...
متن کاملDifferential Impacts of Virus Diversity on Biomass Production of a Native and an Exotic Grass Host
Pathogens are common and diverse in natural communities and have been implicated in the success of host invasions. Yet few studies have experimentally measured how pathogens impact native versus exotic hosts, particularly when individual hosts are simultaneously coinfected by diverse pathogens. To estimate effects of interactions among multiple pathogens within host individuals on both transmis...
متن کاملPromoting Native Vegetation and Diversity in Exotic Annual Grass Infestations
Exotic plant invasions are especially problematic because reestablishment of native perennial vegetation is rarely successful. It may be more appropriate to treat exotic plant infestations that still have some remaining native vegetation. We evaluated this restoration strategy by measuring the effects of spring burning, fall burning, fall applied imazapic, spring burning with fall applied imaza...
متن کاملNative herbivores and plant facilitation mediate the performance and distribution of an invasive exotic grass
1. Exotic plant species have become increasingly prominent features of ecological landscapes throughout the world, and their interactionswith native and exotic taxa in these novel environments may play critical roles inmediating the dynamics of such invasions. 2. Here, we summarize results from comparative and experimental studies that explore the effects of two factors – herbivory and facilita...
متن کاملPotential selection in native grass populations by exotic invasion.
Ecological impacts of invasive plant species are well documented, but the genetic response of native species to invasive dominance has been often overlooked. Invasive plants can drastically alter site conditions where they reach dominance, potentially exerting novel selective pressures on persistent native plant populations. Do native plant populations in old exotic invasions show evidence of s...
