Researchers have suggested that species—community interactions determine invasion success. Therefore, it is likely small biological differences between species interact with habitat characteristics to produce distinct patterns of distribution and abundance throughout a new range. In this study we test the hypothesis in sharing an identical set i deal weed characteristics" are explicable terms species—specific responses environmental variation within their Using multifactor experiments,...
Background and AimsSeed survival in the soil contributes to population persistence community diversity, creating a need for reliable measures of seed bank persistence. Several methods estimate persistence, most which count seedlings emerging from samples. Seasonality, depth distribution presence (or absence) vegetation are then used classify species' into persistent or transient, often synthesized longevity index. This study aims determine if counts samples yield estimates this is correlated...
Due to the widespread use of pesticides and lack floral resources in many agricultural landscapes, beekeepers have moved numerous honey bee colonies protected areas which could shelter an important diversity wild bees. Here, we investigated seasonal dynamics competition between bees through a two‐year study plant–bee networks Mediterranean area. We recorded visitation rates four groups: bees, small large bumblebees. Our reveals that for induced by is especially strong during early spring...
Abstract Understanding how plant traits interact with climate to determine niches is decisive for predicting change impacts. While lifespan and seed size modify the importance of germination timing, such as base temperature water potential directly translate climatic conditions into impacting performance in later life stages. Yet we do not know temperature, potential, mass, are related. We tested relationships between germination, while controlling bioclimatic regions. also quantified...
Black rats, Rattus rattus, and mat-forming iceplants, Carpobrotus aff. acinaciformis edulis, are pervasive pests on Mediterranean islands. Their cumulative impacts native biotas alter the functioning of island ecosystems threaten biodiversity. A report is given here first attempt to eradicate both taxa from a protected nature reserve in south-eastern France (Bagaud Island). In order minimise unwanted hazardous outcomes produce scientific knowledge, operations were embedded four-step strategy...
Background and aims -The conservation of a rare endangered plant species requires clear knowledge its habitat distribution.Species Distribution Models (SDM) are generally applied to characterize species' suitable habitats predict their potential distribution.However, this method is not well suited that require fine spatial scale approach.Co-occurring targeted can be used define taking into account biotic interactions.Our aim was construct predictive model the presence Limonium girardianum,...
Abstract Invasive species management (eradication or control) can be used to promote native plant restoration. The objective of this study is evaluate different treatments guide the selection future modalities for eradication (i.e. elimination all individuals in a population) Carpobrotus sp. from strict nature reserve. Two removal methods were tested: (1) living removal; (2) and litter removal. To assess effectiveness each treatment, we studied recolonization vegetation, , soil erosion...
In the context of global pollinator decline, little is known about protection status and ecology many species. This lack knowledge particularly important for Mediterranean protected areas that harbor diverse communities are subject to considerable anthropogenic pressures. Calanques National Park (85 km2), which located near Marseille (France), dominated by low-vegetation habitats, such as phrygana scrublands. These habitats offer favorable conditions species due amount floral resources....
Abstract Question Species of the genus Carpobrotus , or ice plant, are succulent mat‐forming perennial herbs often introduced for soil stabilization. They common in coastal environments and may thus threaten island biodiversity. While their effects well known on soils, plant communities associated fauna, control vegetation recovery poorly documented. The aim paper is to describe community trajectories after removal. Location Bagaud: a 58‐ha Mediterranean island, southern France. Methods its...
Abstract The Maritime and Ligurian Alps represent a regional hotspot of plant biodiversity found in the Mediterranean. Historical factors, complex geomorphology habitat diversity may have played key roles to mould biogeographical singularity this area. This study represents first phylogeographic attempt better assess evolutionary history an endemic ( Gentiana ligustica ), which is throughout hotspot, across large altitudinal ecological gradient. Here, we examine how historical topographical...
Biological invasions are one of the world's leading causes biodiversity loss. Islands particularly good models for studying impact invasive species. Bagaud island (58 ha), which is part Port-Cros National Park (southeastern France), currently suffering an invasion Carpobrotus. A restoration project has been established with aim eradicating these species to protect native ecosystems. The objective present study was examine plant composition local vegetation and seed bank (in litter soil)...
Abstract Variation in pollen flow, mating performances, and seed dispersal were examined using direct indirect approaches contrasted hedgerow networks (i.e., dense vs. sparse) of the distylous Primula vulgaris . Seed reached negligible distances, no difference was observed between two networks. On contrary, flow through Bombylius sp. activity impeded network. Furthermore, P. found to be partially self‐compatible our study site. The lower network, especially small populations, is likely have...
L’utilisation de populations locales comme source plantes dans le cadre processus restauration écologique permet parvenir à la fois réhabilitation sites pollués par des composés inorganiques et conservation biologique. Les sols contaminés étant généralement pauvres en nutriments présentant une structure hautement altérée, il est supposé que les associations mycorhiziennes rhizobiennes jouent un rôle non négligeable colonisation végétale. Ainsi, l’objectif ce travail a été d’évaluer capacité...
