“…Due to the multitude of ways plants influence aquatic food webs, environmental conditions, etc., there are likely other ways that invasive species could influence fish and macroinvertebrate communities. Invasive species have specific traits that facilitate their invasion such as high growth rates, defense strategies (i.e., allelopathy), and adaptations to a broad range of environmental conditions (see review by Ren & Zhang, 2009). We posit that if invasive species affect fish and macroinvertebrate communities differently than natives, it is due to traits that enable them to invade because they are responsible for changes to aquatic environments.…”

Effects of invasive macrophytes on freshwater fish and macroinvertebrate communities: the role of invasive plant traits

Biological invasions of aquatic plants (i.e., macrophytes) are a worldwide phenomenon, and within the last 15 years researchers have started to focus on the influence of these species on aquatic communities and ecosystem dynamics. We reviewed current literature to identify how invasive macrophyte species impact fishes and macroinvertebrates, explore how these mechanisms deviate (or not) from the accepted model of plant-fish interactions, and assess how traits that enable macrophytes to invade are linked to effects on fish and macroinvertebrate communities. We found that in certain instances, invasive macrophytes increased habitat complexity, hypoxia, allelopathic chemicals, facilitation of other exotic species, and inferior food quality leading to a decrease in abundance of native fish and macroinvertebrate species. However, mechanisms underlying invasive macrophyte impacts on fish and macroinvertebrate communities (i.e., biomass production, photosynthesis, decomposition, and substrate stabilization) were not fundamentally different than those of native macrophytes. We identified three invasive traits largely responsible for negative effects on fish and macroinvertebrate communities: increased growth rate, allelopathic chemical production, and phenotypic plasticity allowing for greater adaptation to environmental conditions than native species. We suggest that information on invasive macrophytes (including invasive traits) along with environmental data could be used to create models to better predict impacts of macrophyte invasion. However, effects of invasive macrophytes on trophic dynamics are less well-known and more research is essential to define system level processes.

“…Although theoretical approaches allow a general understanding of the success of invasive plant species (Sher and Hyatt 1999;Kolar and Lodge 2001;Shea and Chesson 2002;Ren and Zhang 2009), the response of a particular species to an ecological context may reveal which traits facilitate its invasive behavior (Richardson and Pysek 2006).…”

“…Recently, Ren and Zhang (2009) compiled a list of eight invasion mechanisms and grouped them into three main categories: adaptation to physical environment, resource competition-utilization, and enemy release. These authors found that many species combine several mechanisms, and these might be important in different periods of plant invasion.…”

Comparisons between native and invasive congeners are potentially useful approaches for identifying characteristics that promote invasiveness. Those traits for which an invasive exhibits superior ecological performance are likely to contribute to its invasiveness. We tested the hypothesis that invasive tree species have better ecological performance in early life cycle stages than native species in forests where they coexist. We studied locally sympatric populations of the invasive Ardisia elliptica and the native A. obovata (Myrsinaceae) in Puerto Rico. We compared spatial distribution, herbivory and growth in seedlings, seed germination in the field and under controlled conditions, and fruit production. We found the distribution of each species was aggregated in the three categories of size (seedlings, juveniles and adults) and the populations partially overlapped. The invasive species was the most abundant species in every category of size. The two species did not differ in percentage of leaf area consumed and seedlings of both species had the same relative growth rate (RGR) in the forest. However, the invasive species had higher germination success in the field, faster mean germination time in the lab and higher fruit production. It appears that the success of A. elliptica is not through escape from pathogens or herbivores, but by a better performance in fruiting and seed germination in the forest.

“…Plant reproduction behaviors are closely associated with their acquired living resources [13][14]16]. A resource competition exists between growth and reproduction in plants, and the RA strategy of plants controls and balances the dynamics between growth and reproduction [13][14][15][16][17] because living resources in a habitat form one of the most important environmental factors of survival [18]. Meanwhile, the variations in RA strategy play an important role in plant adaptation to environmental changes [14][15]19].…”

Plant invasion succeeds because of such invader characteristics as fecundity and high-efficiency multiple reproduction modes. The acquisition of individual resources and the benefits of individual fitness are driven by optimum patterns of life history and trade-offs of reproductive allocation (RA) in plants, and variations in RA strategy play an key role in plant adaptation to environmental changes. Thus determining the RA strategy of invasive plants is important for understanding the successful mechanism underlying plant invasion. This study aims to determine the reproductive allocation (RA) strategy of two herbaceous invasive plants (Conyza canadensis and Solidago canadensis) across different cover classes in eastern China. Plant height, maximum branch length, the reproductive branch number, aboveground biomass, the amount of reproductive investment, and the coefficient of RA of the two plants decreased with increasing cover class (although the changes were not pronounced). Thus the two plants may decrease physiological investment on reproductive behavior and reduce RA under competitive conditions because of interspecies competition that progressively decreased and intraspecific competition that gradually increased with increasing cover class. The RA of the two plants may be principally influenced by plant community composition at low cover classes, but by soil pH at high cover classes. This may be the outcome that soil pH of the two plants decreased with increasing cover class significantly. Thus, intraspecific competition for resources may play an important role in the RA strategy of the two plants under high cover class.
