“…Biological invasions impact biodiversity, ecosystem services, and human well-being globally, and further research on invasion dynamics, impacts, and options for management is needed to identify options for sustainable management (Pimentel 2002;Pyšek and Richardson 2010). Research on invasive species is normally approached from the domain of ecology, and more recently economics.…”

Invasive alien trees impact the environment and human livelihoods. The human dimensions of such invasions are less well understood than the ecological aspects, and this is hindering the development of effective management strategies. Semi-structured interviews were undertaken to investigate the knowledge and perceptions of Prosopis between different stakeholder groups. Chi-squared tests, Welch ANOVAs, and Principle Component Analyses were run. Factors such as land tenure and proximity to invasions were especially important for explaining differences in perceptions and practices relating to Prosopis among different stakeholder groups. Most respondents were aware of Prosopis and considered it to be invasive (i.e., spreading). Costs associated with Prosopis were perceived to exceed benefits, and most stakeholders wanted to see a reduction in the abundance of Prosopis stands. The mean total cost for the management of Prosopis was US$ 1914 year -1 per farm, where costs ranged from under US$ 10 to over UD$ 500 per ha based on invasion densities and objectives for control. The findings highlight the need for more effective management interventions.

“…Bromley et al 2016). Biological invasions can include both hosts and their parasites and have been widely recognised as potential major threats to marine biodiversity and in some cases, this has caused significant economic losses (Pimentel et al 2001; Prenter et al 2004). Euendoliths carried along with their hosts can either themselves infest the local mollusc populations that have not yet developed a resistance or interact with other microborers that were originally non-pathogenic.…”

Anamorphic ascomycetes have been implicated as causative agents of diseases in tissues and skeletons of hard corals, in tissues of soft corals (sea fans) and in tissues and shells of molluscs. Opportunist marine fungal pathogens, such as Aspergillus sydowii, are important components of marine mycoplankton and are ubiquitous in the open oceans, intertidal zones and marine sediments. These fungi can cause infection in or at least can be associated with animals which live in these ecosystems. A. sydowii can produce toxins which inhibit photosynthesis in and the growth of coral zooxanthellae. The prevalence of many documented infections has increased in frequency and severity in recent decades with the changing impacts of physical and chemical factors, such as temperature, acidity and eutrophication. Changes in these factors are thought to cause significant loss of biodiversity in marine ecosystems on a global scale in general, and especially in coral reefs and shallow bays.

“…This is one of the most important topics in conservation efforts (Cristescu and Boyce 2013). In agricultural systems, invasive plants may cause economic losses of up to 40 % (Pimentel et al 2001). To minimize such losses, substantial time and effort must be invested in eradicating invasive populations and preventing their further spread (Pichancourt et al 2012).…”

Generating an agricultural risk map based on limited ecological information: A case study using Sicyos angulatus

In this study, we propose a method for estimating the risk of agricultural damage caused by an invasive species when species-specific information is lacking. We defined the ''risk'' as the product of the invasion probability and the area of potentially damaged crop for production. As a case study, we estimated the risk imposed by an invasive weed, Sicyos angulatus, based on simple cellular simulations and governmental data on the area of crop that could potentially be damaged in Miyagi Prefecture, Japan. Simulation results revealed that the current distribution range was sufficiently accurate for practical purposes. Using these results and records of crop areas, we present risk maps for S. angulatus in agricultural fields. Managers will be able to use these maps to rapidly establish a management plan with minimal cost. Our approach will be valuable for establishing a management plan before or during the early stages of invasion.
