Invasion of forest ecosystems by invader plants and fires are two the most serious environmental problems in world. Climate change is believed to strongly influence these processes, invasibility invasive alien (IAPs) likely enhance landscape degradation. Therefore, it urgent study germinative behaviour relation fire detect possible barrier species IAPs among native species. Tree usually damagin...

Alien invasive species have been a seriously environment issue in the whole world. The ecological damages and economic influences of alien invasive species are analyzed in this article, and the government is suggested to strengthen the quarantine services, strictly manage the intentional introduction of alien species, and implement the risk supervision system for the introduction of alien species.

Seed dispersal is one of the most important mechanisms shaping biodiversity, and animals are one of the key dispersal vectors. Animal seed dispersal can directly or indirectly be altered by invasive organisms through the establishment of new or the disruption of existing seed dispersal interactions. So far it is known for a few gastropod species that they ingest and defecate viable plant seeds ...

BACKGROUND AND AIMS Flowering phenology is a potentially important component of success of alien species, since elevated fecundity may enhance invasiveness. The flowering patterns of invasive alien plant species and related natives were studied in three regions with Mediterranean-type climate: California, Spain and South Africa's Cape region. METHODS A total of 227 invasive-native pairs were ...

South Africa's natural resources and ecosystems are negatively affected by Invasive Alien Plants (IAPs). We used a life-cycle approach to assess the environmental socio-economic impacts of using IAPs for electricity generation in Africa or exported Netherlands. Supply chain greenhouse gas (GHG) emissions from pellets, excluding land use change-related GHG emissions, 31.5 gCO2eq MJ?1 31.2 An add...

Rapid urbanization is placing increased pressure on natural, restored and designed ecosystems to provide services growing human populations. The establishment spread of invasive alien species within around urban areas threaten biodiversity ecosystem functioning, the they provide. Consequently, there a need protect manage where invasions will have greatest socio-ecological impact. Limited resour...

Recent advances in the field of plant community phylogenetics and invasion phylogenetics are mostly based on plot-level data, which do not take into consideration the spatial arrangement of individual plants within the plot. Here we use within-plot plant coordinates to investigate the link between the physical distance separating plants, and their phylogenetic relatedness. We look at two vegeta...

Fire management practices affect alien plant invasions in diverse ways. I considered the impact of six fire management practices on alien invasions: fire suppression, forest fuel reduction, prescription burning in crown-fire ecosystems, fuel breaks, targeting of noxious aliens, and postfire rehabilitation. Most western United States forests have had fire successfully excluded for unnaturally lo...

To better understand the effect of species traits on plant invasion, we collected comparative data on 20 reproductive and dispersal traits of 93 herbaceous alien species in the Czech Republic, central Europe, introduced after 1500 A. D. We explain plant invasion success, expressed by two measures: invasiveness, i.e. whether the species is naturalized but non-invasive, or invasive; and dominance...

Many alien plants are thought to be invasive because of unique traits and greater phenotypic plasticity relative to resident species. However, many studies of invasive species are unable to quantify the importance of particular traits and phenotypic plasticity in conferring invasive behavior because traits used in comparative studies are often measured in a single environment and by using plant...
