“…The presence of tannin was confirmed by adding 3 drops of 0.1% FeCl 3 to 1 mL of the aqueous fraction [24]. The Folin-Ciocalteu method was used to quantify the total tannin content [25], by preparing a 100 mg/mL stock solution of tannic acid and making serial dilutions.…”

Contamination of water by Pb2+ and the threat of invasive vegetation affects the quality and quantity of water accessible to all life forms and has become a primary concern to South Africa and the world at large. This paper synthesized, characterized, and evaluated the resins from tannin-rich invasive Acacia species as an environmentally benign Pb 2+ adsorbent. The analysis of the pore volume and surface area of the resins reveals a small pore dimension of 9 × 10 −3 cc/g and large surface area (2.31-8.65 m 2 /g), presenting suitable physical parameters for adsorption of Pb 2+ . Langmuir model offers the best correlation data at pH 6 with maximum monolayer coverage capacity of 189.30, 105.70 and 98.82 mg/g for silver, black and green wattle tannin resins in aqueous solutions, respectively. The kinetic data suitably fits into a pseudo-second-order model, with the Dubinin-Radushkevich adsorption energy (E) ≤ 7.07 KJ/mol and intra-particle diffusion model confirming an associated physisorption process within the bio-sorption system. The thermogravimetric analysis (TGA) and Fourier-transform infrared (FT-IR) data of the resins were informative of the high thermal stability and chelating functionality such as -OH and -NH 2 responsible for the removal of Pb 2+ . All the resins showed good adsorption characteristics while silver wattle tannin resin has the best adsorption capacity compared to black and green wattle tannin resins. This study provides a prototype adsorbent from invasive plants for the removal of Pb 2+ in water.

“…The time point at which exponential growth begins is referred to as TG, and the population growth rate is GROWTH. A bottleneck period and subsequent exponential growth are common features of invasion models Guillemaud et al, 2011). Meanwhile the source population remains at constant size (NS).…”

“…Accumulated genetic evidence not only suggests that invasions often feature complex histories, but also highlights several key and relatively simple components (Guillemaud et al, 2011). For example, a common finding is that multiple invading populations may originate from multiple geographically distinct sources (Miller et al, 2005;Keller, 2009;Guillemaud et al, 2010).…”

“…For example, a common finding is that multiple invading populations may originate from multiple geographically distinct sources (Miller et al, 2005;Keller, 2009;Guillemaud et al, 2010). An alternative and also common scenario for the origin of multiple invading populations is a spatial expansion/serial founding from a single source, for example, an invasion front (Clegg et al, 2002;Estoup et al, 2004) or a bridgehead process (Guillemaud et al, 2011;Lombaert et al, 2012), in which one successfully established population is the source for many other populations. Lastly, admixture between distinct source populations is common between invaded populations that have existed for some time due to migration exchange or merging (Besnard et al, 2014).…”

Using ABC and microsatellite data to detect multiple introductions of invasive species from a single source

et al. 2015

The introduction of invasive species to new locations (that is, biological invasions) can have major impact on biodiversity, agriculture and public health. As such, determining the routes and modality of introductions with genetic data has become a fundamental goal in molecular ecology. To assist with this goal, new statistical methods and frameworks have been developed, such as approximate Bayesian computation (ABC) for inferring invasion history. Here, we present a model of invasion accounting for multiple introductions from a single source (MISS), a heretofore largely unexplored model. We simulate microsatellite data to evaluate the power of ABC to distinguish between single and multiple introductions from the same source, under a range of demographic parameters. We also apply ABC to microsatellite data from three invasions of bumblebee in New Zealand. In addition, we assess the performance of several methods of summary statistics selection. Our simulated results suggested good ability to distinguish between one-and two-wave models over much but not all of the parameter space tested, independent of summary statistics used. Globally, parameter estimation was good except for bottleneck timing. For one of the bumblebee species, we clearly rejected the MISS model, while for the other two we found inconclusive results. Since a second wave may provide genetic reinforcement to initial colonists, help relieve inbreeding among founders, or increase the hazard of the invasion, its detection may be crucial for managing invasions; we suggest that the MISS model could be considered as a potential model in future theoretical and empirical studies of invasions.

“…These results suggest that initial H. armigera populations were established by a large number of individuals, were derived from introductions from different sources and/or were submitted to a bridgehead effect (GUILLEMAUD et al, 2011). In a bridgehead effect an invasive population acts as the source of the colonists that invade another place, with some admixture in the source population (LOMBAERT et al, 2010).…”
