Several invasive alien snails are considered a threat to agriculture and horticulture. The development of rapid methods for reliable prediction their impacts on crops is major challenge in agricultural science invasion biology. use comparative functional response tests could give insight the potential impact herbivorous natural vegetation. It has been hypothesised that superior competitors reso...

Abstract Invasive species may act as a functional filter on native communities by differentially affecting with different trait values. Across environments, invasive plants typically display traits associated high resource acquisition and fast growth. Conversely, plants, especially those in water-limited tend to adopt one of two strategies: growth during availability avoid stress (resource-acqu...
