Aquatic macrophytes, often also called hydrophytes, are key components of aquatic and wetland ecosystems. This review is to briefly summarizes various macrophyte classifications, and covers numerous aspects of macrophytes' role in wetland ecosystems, namely in nutrient cycling. The most widely accepted macrophyte classification differentiates between freely floating macrophytes and those attached to the substrate, with the attached, or rooted macrophytes further divided into three categories: floating-leaved, submerged and emergent. Biogeochemical processes in the water column and sediments are to a large extent influenced by the type of macrophytes. Macrophytes vary in their biomass production, capability to recycle nutrients, and impacts on the rhizosphere by release of oxygen and organic carbon, as well as their capability to serve as a conduit for methane. With increasing eutrophication, the species diversity of wetland macrophytes generally declines, and the speciose communities are being replaced by monoculture-forming strong competitors. A similar situation often happens with invasive species. The roles of macrophytes and sediment microorganisms in wetland ecosystems are closely connected and should be studied simultaneously rather than in isolation.

“…However, practices of data production, interpretation, and use are also contested (Stromberg et al 2009, Crall et al 2010, Lavoie 2010, Davis et al 2011, Boonman-Berson et al 2014. For instance, different interpretations of the same data sets have led to opposing assessments of the impact of invasive species on native species (Gurevitch andPadilla 2004, Clavero andGarcía-Berthou 2005).…”

“…A study on the social construction of purple loosestrife, an invasive plant in North American wetlands, found that the media attributed more negative impacts to the plant than scientists did (Lavoie 2010). In contrast, media and scientific reports portrayed a comparable image of lionfish, although the media's language use was more inflated.…”

“…Recognized as powerful areas of meaning-making in society, science and the media ultimately shape public views, policy, and management of invasive species (Stromberg et al 2009, Lavoie 2010. As a growing literature has highlighted, a species labeled as invasive is often perceived and valued differently by different people, and these divergent constructions usually lead to management disputes (Perry and Perry 2008, Weeks and Packard 2009, Marshall et al 2011, Shine and Doody 2011, Dickie et al 2014.…”

Controversies and consensus on the lionfish invasion in the Western Atlantic Ocean

ABSTRACT. This study investigates how the lionfish (Pterois sp.) invasion of the Western Atlantic Ocean has been socially constructed by natural scientists, the media, and stakeholders associated with various marine protected areas in the Caribbean. By examining the use of data and metaphors by these actors, I identify where invasion discourses converge and diverge. Although consensus exists regarding the non-nativeness, introduction vector, and successful establishment of lionfish throughout the region, I also identify uncertainty surrounding lionfish impact and controversies regarding lionfish management and control. The dominant discourse frames lionfish as a threat and control efforts as a war to keep the enemy at bay, and promotes lionfish hunting and consumption by humans: the "ultimate predators." However, this view is challenged by a coalition that questions the safety, effectiveness, and morality of the practices promoted by the kill-and-eat lionfish coalition. A nascent discourse that frames lionfish as fulfilling the role of overexploited native species, primarily expressed in socioeconomic terms, is shifting lionfish impact perception from negative to positive among some stakeholder groups. Whereas the dominant discourse views humans as helping nature to regain balance through lionfish hunting, a minority coalition views lionfish as part of the ecosystem, where a new equilibrium will be reached. This study shows that scientific data and metaphors, amplified by the media, facilitated initial understanding of the lionfish phenomenon and are used to legitimize claims. In time, however, local knowledge and societal values have intermingled with scientific data, sometimes challenging scientific discourses, and contributing to a richer understanding of the invasion as a social-ecological phenomenon.

“…Thus, studies on invasive plants and animals become all the more important in the present scenario. The first step in the control of such species is to identify the species with the greatest impact (Lavoie 2010). Invasive species are causing havoc in urban ecosystems as the developing cities make rather the preferred habitats for such plants which being mostly ruderal are capable of rapid colonization in disturbed habitats (Dar et al 2015).…”

Invasion by Conyza sumatrensis alters soil microbial community structure in urban ecosystems

Introduction: Whether invasive plants stimulate or inhibit the soil microbial diversity is still an open question. Despite large-scale invasion by Conyza sumatrensis (Retz.) E. Walker in the urban ecosystems of the Srinagar city of the Kashmir Himalayan region, limited information exists on its impact, particularly, on the belowground microbial diversity. The present study was thus conducted to compare the soil microbial (bacterial and ascomycetous fungal) diversity between the sites invaded by C. sumatrensis and un-invaded (control) sites. Methods: Soil metagenome was extracted from C. sumatrensis invaded and un-invaded plots at the three study sites. A total of six plots (5 × 5 m each in size), including three invaded by C. sumatrensis and three un-invaded plots were nested within each study site. DNA after amplification was subject to denaturing gradient gel electrophoresis (DGGE); the bands were extracted from the DGGE gel, re-amplified, and sequenced for identification of the species.
