Invasiveness of Linaria vulgaris (yellow
toadflax). Edition No. 1
VDM Publishing House, Dec 2008, Pages: 168
This book explores some of the theoretical
foundations of invasion ecology in a practical,
applied way using Linaria vulgaris (yellow toadflax)
as a case study, and it provides information that
will improve the ecological management of invasive
plant species. First, the question of how soil
disturbance and propagule pressure affect plant
invasions is addressed. Second, while plant
invasions are usually viewed and managed at the
species level, it is a fundamental biological
principle that population growth rate will vary
along a habitat suitability gradient. The varying
invasiveness of L. vulgaris is discussed, and a
method is presented to quantify population
invasiveness, allowing for targeted management of
populations within a given habitat, rather than
managing the species as a whole. Finally, plant
invasions are often associated with soil
disturbance, fire and grazing, and it is generally
assumed that invasive species respond favorably to
these disturbances while native species may decline
in abundance. The effects of these disturbances, as
well as that of herbicide, on existing L. vulgaris
populations and the extant plant community are
discussed.
