For decades, the Texas A&M Univ. campus has been a center for USDA ornamental plant introductions. Historically, horticultural nurseries on the Texas A&M Univ. campus have served as foci from which exotic plants have dispersed and colonized surrounding areas. Pistachia chinensis, Ulmus parvifolia, Ligustrum quihoui, Ligustrum lucidum, and Sapium sebiferum have all established themselves on or near the campus and can be traced back to early introductions. Many Ligustrum taxa including selections of L. quihoui were screened at Texas A&M College in the 1930s. Clones of this species varied greatly in their ability to naturalize. The invasion lag phase and range of expansion varied with both clone and species. It is suggested that potential exotic ornamental plant introductions be carefully evaluated for their potential to become non-native invasive species as well as for their ornamental characteristics.

Abstract Allelopathy, or the process by which plants influence the growth and performance of their neighbours through the release of chemicals, may play a key role in mediating the impacts of non-native invasive species on their neighbours. The Novel Weapons Hypothesis purports that non-native invasive species are in part successful because they produce harmful allelochemicals to which resident species are particularly susceptible because residents lack a shared evolutionary history with the invader. While allelopathic non-native invaders may reduce the growth and performance of neighbours through direct phytotoxicity, they may more often exert negative impacts through disruption of biotic interactions among resident species. Allelopathy by non-native plants may disrupt mutualisms between resident plants and microbes, plant-herbivore interactions or existing competitive and facilitative interactions among resident plants. For example, several non-native plants are known to disrupt the mutualism between resident plants and mycorrhizal fungi, reducing resident plant fitness to the benefit of the invader. Allelopathic non-natives may also disrupt interactions among resident plants and their herbivores when allelochemicals also influence herbivore behaviour or fitness. Alternatively, biotic interactions can also be protective for resident species, which may be less susceptible to the impacts of non-native species when their mutualisms are intact. As we advance our understanding of allelopathy and its role in mediating the impacts of invasive plant species, we may gain new insights by viewing invasions within a network context rather than focusing on pairwise interactions.

Plastic Responses

Abstract Biological invasions can create novel competitive interactions and force ecological shifts in both native and invasive species. Anuran tadpoles are able to modify their behaviour, morphology, growth and development to cope with competitive pressure. This plasticity is a good target for natural selection and can drive rapid evolutionary changes in response to novel interactions. Here, we explore changes in plastic responses and fitness of competing invasive and native tadpoles by exposing tadpoles from different locations with contrasting evolutionary histories to the same set of varied competitive conditions. Eggs were collected from one site near the first introduction of the invasive frog (~110 years of coexistence) and from a second site that was invaded recently. We hypothesized less favourable outcomes for the invasive species in long-coexisting populations, where the native competitor might have developed adaptive responses. Most results support the hypothesis. Where the invasion was older, invasive tadpoles exposed to native competitors grew less, developed more slowly and displayed morphologies linked to competitive stress, whereas the developmental stability and canalization of native tadpoles increased. On the whole, the asymmetric competitive relationship thus appeared to approach symmetry after ~35 generations, highlighting a noteworthy example of rapid adaptation after an invasion.
