Titre : Effect of varying Alternanthera philoxeroides (alligator weed) cover on the macrophyte species diversity of pond ecosystems: a quadrat–based study Type de document : Imprimé Auteurs : Anindita Chatterjee ; Anjana Dewanji Année de publication : 2014 Article en page(s) : 343-355 Langues : Anglais (eng) Catégories : [CBNPMP-Thèmes] Plantes subspontanées, naturalisées, envahissantes Résumé : This year-long study, covering three main seasons of India, focused on enumerating the effect of varying cover of Alternanthera philoxeroides (alligator weed) on the associated macrophyte species diversity of the littoral region of natural pond ecosystem. A total of 192 quadrats were randomly placed in the littoral region of 12 similar ponds containing varying degrees of A. philoxeroides infestation to estimate A. philoxeroides ‘cover (%)’ and number of associated macrophyte species in each quadrat. Overall, 20 associated macrophyte species, including 16 aquatic/ littoral-associated, 2 non-aquatic species, and grasses and sedges, were found to be present. A. philoxeroides infestation was categorized into 4 cover grades (Grade I-IV) from lowest (no/negligible: <10% cover) to highest (>60% cover). For each season, significant differences in the total number of associated macrophyte species across the 4 A. philoxeroides cover grades were found. A Poisson-regression model showed that for each season, even when the effect of other invasive species was adjusted, the number of associated native macrophyte species in a quadrat decreases significantly with increase in A. philoxeroides cover. A comparison of the quadrat communities between the lowest grade (Grade I) and highest grade (Grade IV) of A. philoxeroides infestation showed a significant reduction of species richness, diversity and evenness from the lowest to the highest infestation grades. Again, Mann-Whitney U tests further revealed that the number of native macrophyte species was significantly lower at highest (Grade IV) A. philoxeroides infestation than that at lowest infestation (Grade I). The presence of multiple invaders in A. philoxeroides infested aquatic ecosystems is also reported, indicating probable facilitative interactions between A. philoxeroides and other invasive species. The socio-economic valuation of some important native plants, which were found to be significantly reduced at high infestation levels of A. philoxeroides, has also been highlighted.

Our major objectives were to study soil organic matter in the two stands to determine whether significant biochemical modifications of the C cycle occurred since stand establishment, and to evaluate the effect of the two tree species on soil formation.The study area is part of the Sicani range (western Sicily, Italy), and is characterised by homogeneous environmental features (topography, geology, slope, exposition, climate, etc.). Ten profiles were sampled in a plantation of Pinus halepensisand one of Cedrus atlanticafor each stand. Microbial biomass activity (qCO2, and Cmic:Corg), organic C contents, and organic C mineralization rates were compared between the Ah and Bw horizons of the soils in the two stands. The microbial biomass activity in A-horizons differed appreciably. The metabolic quotient was higher under Pinushalepensis while the Cmic to Corg ratio was higher under Cedrus atlantica, which indicated a possible stressed condition for soil microbial biomass in the Pinus halepensisstand The turnover of decomposable C did not differ significantly between the two soils, but the A-horizons of the Cedrus atlantica site appeared poorer in total organic C content.

Titre : Effects of landscape structure on the invasive spread of black cherry Prunus serotina in an agricultural landscape in Flanders, Belgium Type de document : Imprimé Auteurs : Bart Deckers ; Kris Verheyen ; Martin Hermy ; Bart Muys Année de publication : 2005 Article en page(s) : 99-109 Langues : Français (fre) Catégories : [CBNPMP-Thèmes] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Prunus serotina Ehrh. Résumé : Analysing invasive spread from a landscape ecological perspective forms an important challenge in plant invasion ecology. The present study examines the effects of landscape structure on the spatial and temporal dynamics of an expanding black cherry Prunus serotina population within a rural landscape in Flanders, Belgium, carrying a dense network of interconnected hedgerows. The study area, 251 ha in size, harboured a total of 2962 P. serotina individuals. The population was characterised by a negative exponential age distribution, a high growth rate and an early and continuous reproduction throughout the species’ life cycle. The historical rate of spread of the species through the hedgerow network progressively increased with time, especially during the last decade. Spatial point pattern analysis revealed that the individuals had a significantly clustered distribution pattern and were spatially aggregated around seed sources, hedgerow intersections and roosting trees. Logistic regression analysis confirmed the effect of landscape structure on P. serotina occurrence, suggesting directional long distance dispersal by avian dispersal vectors, resulting in a differential seed pressure throughout the hedgerow network due to the preference of dispersing birds for roosting in structurally rich hedgerow with large trees near hedgerow intersections. Hence, the distribution of P. serotina in agricultural landscapes was strongly mediated by dispersal processes. Furthermore, decreasing spatial aggregation along the species life cycle, with especially seedlings and saplings being significantly aggregated while adult individuals were mostly distributed at random, and a relative outward shift of seedling recruitment curves with time indicate density dependent mortality, probably caused by intraspecific competition.

Swingle, 1916 Verticillium nonalfalfae Résumé : The naturally occurring Verticillium nonalfalfae shows promise for biocontrol of the highly invasive Tree of Heaven (Ailanthus altissima), but might also bear a risk for non-target tree species. In this study, we conducted inoculations on potted seedlings of A. altissima as well as on eight indigenous and two invasive tree species associated with Tree of Heaven in Austria. Although vascular discolourations developed in all inoculated tree species, V. nonalfalfae was reisolated from Ailanthus and eight of the ten non-target-species, whereas typical disease symptoms and mortality only occurred on A. altissima. Results confirmed high susceptibility (S) of A. altissima to V. nonalfalfae but indicated tolerance (T) of Acer campestre, Acer pseudoplatanus and Quercus robur, possible resistance (PR) of Fraxinus excelsior, Populus nigra, Tilia cordata, Ulmus laevis and Ulmus minor and resistance (R) of Fraxinus pennsylvanica and Robinia pseudoacacia to this potential biocontrol agent. Results from seedling inoculations were confirmed by cursory field observations in Ailanthus-inoculated forest stands, where admixed A. campestre, A. pseudoplatanus, F. excelsior, Populus alba, R. pseudoacacia and U. laevis canopy trees remained asymptomatic, while mortality was induced in Ailanthus.
