Predicting biological invasions Development and application of a model for the analysis of plant invasions
نویسنده
چکیده
The principle of the model is a dissection of an idealized invasion process into invasion steps and stages (INVASS model). The basic structure can be depicted as a staircase: five invasion stages (0 to 4) are connected through four invasion steps (1 to 4). The stages describe the status of the species during the invasion, whereas the steps illustrate the processes. The invasion steps summarize the main difficulties the species may be confronted with during the process.

Approaches for testing herbivore effects on plant population dynamics
1. As plant invasions pose one of the greatest threats to biodiversity, it is critical to improve both our understanding of invasiveness and strategies for control. Much research into plant invasions and their management, including biological control, assumes strong demographic effects by natural enemies, including herbivores. However, the importance of natural enemies in the regulation of plan...
متن کاملPredicting Invasion Success: Freshwater Fishes in California as a Model
S lakes, and estuaries are among the most highly invaded ecosystems in the world; in many of them, alien organisms are now a significant part of the biota (Cohen 2002). The best-documented invaders in these systems are fishes. Because many fish species are widely introduced, there is concern among scientists and managers over the homogenization of freshwater fish faunas worldwide (McKinney and ...

This paper deals with the numerical solution of a class of reaction diffusion equations arises from ecological phenomena. When two species are introduced into unoccupied habitat, they can spread across the environment as two travelling waves with the wave of the faster reproducer moving ahead of the slower.The mathematical modelling of invasions of species in more complex settings that include ...

Biological invasions form a major threat to the provision of ecosystems productsand services and can affect ecosystems across a wide spectrum of bioclimatic conditions.Therefore, it is important to systematically monitor the spread of species over broad regions. Ithas long been recognized that remote sensing and geographical information system couldcontribute to this capacity. This paper aims t...

Biological invasions can transform our understanding of how the interplay of historical isolation and contemporary (human-aided) dispersal affects the structure of intraspecific diversity in functional traits, and in turn, how changes in functional traits affect other scales of biological organization such as communities and ecosystems. Because biological invasions frequently involve the admixt...
