Invasive plant species are an increasing worldwide threat both ecologically and financially. Knowing the location of these invasive infestations is first step in their control. Surveying for Phragmites australis particularly challenging due to limited accessibility wetland environments. Unoccupied aircraft systems (UAS) a popular choice management ability survey environments high spatial tempor...

Regeneration from vegetative fragments is common in plants that occur disturbed and wet habitats but quantitative data comparing regeneration of different plant parts under various environmental conditions are still scarce. Phragmites australis a dominant keystone wetland species widespread all around the world. It spreads both vegetatively by rhizomes stolons generatively seed. Detached culms ...

Different clones of the wetland grass Phragmites australis differ in their morphology and physiology, and hence in their ability to cope with environmental stress. We analysed the responses of 15 P. australis clones with distinct ploidy levels (PLs) (4n, 6n, 8n, 10n, 12n) and geographic origins (Romania, Russia, Japan, Czech Republic, Australia) to step-wise increased salinity (8, 16, 24, 32, 4...

Experimental studies to determine the nature of ecological interactions between invasive and native species are necessary for conserving and restoring native species in impacted habitats. Theory predicts that species boundaries along environmental gradients are determined by physical factors in stressful environments and by competitive ability in benign environments, but little is known about t...

Isoprene basal emission (the emission of isoprene from leaves exposed to a light intensity of 1000 m mol m 2 s 1 and maintained at a temperature of 30 ∞ C) was measured in Phragmites australis plants growing under elevated CO 2 in the Bossoleto CO 2 spring at Rapolano Terme, Italy, and under ambient CO 2 at a nearby control site. Gas exchange and biochemical measurements were concurrently taken...

Point Pelee National Park, located at the southern-most tip of Canada's mainland, historically supported a large number of herpetofauna species; however, despite nearly a century of protection, six snake and five amphibian species have disappeared, and remaining species-at-risk populations are thought to be in decline. We hypothesized that long-term changes in availability and distribution of c...
