Some work, however, suggests that asexual reproduction can also be advantageous. One situation when. Non-native species diversity of plants and fishes in the contiguous 48 United States is analyzed to measure the influence of human population size, time of modern settlement, area and native.

H. aurantiacum is an apomict – producing much of its seed asexually – and has become a common invasive in North America and New Zealand. The genetic diversity of H. aurantiacum was assessed over its invasive ranges in the Eastern and Western North America, as well as one location from its native range in the Czech Republic.Cited by: 4.

May 24, 2019 · Results and Discussion Rangeland invasive plants composition and diversity A total of 32 invasive plant species belonging to 18 families were identified (Table 1).These species were categorized under woody and non-woody/herbaceous/ broadleaved invasive plants. No invasive grass and sedge species were present.Author: Prof JJ SHARMA. Nov 26, 2014 · The effects of invasive plants on the species diversity of plant communities are controversial, showing either a positive or negative linear relationship. Based on community data collected from forty 5 m×5 m plots invaded by Sphagneticola trilobata in eight cities across Hainan Island, China, we found S. trilobata decreased plant community diversity once its cover was beyond 10%.Cited by: 8.
