Ecology and Invasive potential of Paulownia tomentosa (scrulariaceae) in a hardwood forest landscape / A. Christina W. Longbrake (2001)

Longbrake Editeur : Ohio University Année de publication : 2001 Importance : 174 p. Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes [CBNPMP-Thématique] Forêts (habitat) [CBNPMP-Géographique] Amérique du Nord Mots-clés : Paulownia tomentosa (scrulariaceae) Résumé : Introduction of non-native species is the oldest form of human-induced global change. From the exchange of agricultural crops and domestic animals, to the accidental introduction of weeds and microbes, non-native species have been incorporated into the floras and faunas of all continents and most oceanic islands. These organisms can have marked effects on ecosystems. I wanted to address the following facets of non-native species invasion: (1) What characteristics of ecosystems make them more susceptible to non-native species invasion? and (2) What characteristics of the invader allow invasion? To address these questions, I used a gradient of anthropogenic disturbance common in southeastern Ohio forests: intact secondary forest, forest edge, and aggrading clear cuts. Paulownia tomentosa is a tree native to Asia and thought to have been introduced to North America in the 1840's. The species has naturalized throughout Appalachia. I studied the growth, allocation, establishment, and seed persistence across habitats. I also became interested in the basic ecology of P. tomentosa, particularly the ability of the species to resprout and phenotypic plasticity in naturalized populations. The most important factors in determining the invasive potential of P. tomentosa were disturbance and herbivory. Paulownia tomentosa is an early successional species that can grow rapidly under high light conditions. Seed ecology suggests that the species can form a persistent seed bank. However, light is required for germination and seeds responded positively to soil disturbance. Large gaps may be sufficient to allow seeds in the seed bank to germinate and grow to the canopy. However, the species is very susceptible to herbivory. Plants had to be protected from mammals in order to persist. Even though above- and below-ground competition affected plant growth and allocation, it did not affect the overall success of plants. Paulownia tomentosa can resprout at an early age and initially invests heavily in below-ground biomass. Naturalized populations showed some variability in traits, particularly in those associated with below-ground biomass and growth of roots. Paulownia tomentosa has potential to remain a part of the mixed mesophytic forests of North America since it can form a seed bank, disperse seeds to great distances, and grow quickly once established.

Strategies for a successful plant invasion: the reproduction of Phragmites australis in north-eastern North America / Arnaud Albert in Journal of ecology, 103 (2015) 

Public Citation [article]  inJournal of ecology > 103 (2015) . - 1529-1537 Titre : Strategies for a successful plant invasion: the reproduction of Phragmites australis in north-eastern North America Type de document : Électronique Auteurs : Arnaud Albert ; Jacques Brisson ; François Belzile ; Julie Turgeon ; Claude Lavoie Année de publication : 2015 Article en page(s) : 1529-1537 Langues : Anglais (eng) Catégories : [CBNPMP-Géographique] Amérique du Nord [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Phragmites australis (Cav.) Trin. ex Steud., 1840 Résumé : Knowing the relative contribution of vegetative propagation and sexual reproduction to the dispersal and establishment of exotic plants is crucial for devising efficient control strategies. This is particularly true for the common reed (Phragmites australis), one of the most invasive species in North America. For the first time, we combined in situ field observations and genetic evidence, based on two genotyping techniques, that is microsatellite markers (SSR) and genotyping by sequencing (GBS), to determine the propagation strategies of this invader at its northern distribution limit in North America and especially in roadside ditches. Field observations revealed that, in a region where the common reed is already abundant, both seeds and plant fragments contributed to the establishment of new populations. Newly established individuals originated mostly (84%) from seeds rather than fragments, but a larger proportion of individuals originating from fragments survived the second year compared to seedlings. High genetic diversity among marsh and roadside common reed stands indicated the prime role of sexual reproduction for dispersal. The vast majority of genotypes were found in only one stand; such high genetic variability can only be explained by sexual reproduction. Half the surveyed stands comprised a single clone, suggesting that local expansion mainly occurred vegetatively. As the small proportion of SSR genotypes initially thought to be common between distant stands proved to be distinct (as revealed by GBS data), it is likely that all the stands examined were initially founded by genetically distinct individuals. Synthesis. Our study suggests that long-distance dispersal by seeds is important for the common reed, in marshes and roadsides, while both seeds and plant fragments contribute to short-distance dispersal along roads, at least in regions where the species is already abundant. The success of this invader in North America seems to be attributable to a reproduction strategy combining the advantages of sexuality with those of vegetative propagation. Moreover, this study shows that the GBS approach strongly reduces uncertainties associated with the use of a limited number of markers. This approach is especially valuable for ecologists dealing with an ever-increasing number of invaders, of which few have identified microsatellite markers.
