Abstract Accurate taxonomic identification of alien species is crucial to detect new incursions, prevent or reduce the arrival invaders and implement management options such as biological control. Globally, taxonomy non-native Prosopis problematic due misidentification extensive hybridization. We performed a genetic analysis on several species, their putative hybrids, including both native populations, with special focus invasions in Eastern Africa (Ethiopia, Kenya Tanzania). aimed clarify...
The ability to reproduce via multiple strategies is crucial for the invasion success of alien plant species. Here, we use Carpobrotus taxa (species and hybrids) explore how trade-offs between within these may influence dynamics. Native South Africa, plants are globally prominent in coastal ecosystems, reproducing by seed clonally, frequently hybridizing both native introduced regions. Three genetically distinct clusters were previously identified, with evidence hybridization non-native...
The context‐depency of biological invasions makes it difficult to understand why some species become succesfull invaders and others not. Such understanding requires studying closely‐related invasive non‐invasive alien taxa sharing the same introduction history in environment. We identified this unusual situation Kenya where individuals that founded Prosopis juliflora P. pallida populations are still present original plantations. evaluated field‐measured traits, conducted glasshouse...
Aquatic invasive species are a major threat to native freshwater ecosystems and cause enormous ecological economic damage worldwide. Didymosphenia geminata (Lyngbye) M. Schmidt is an emerging aquatic that spreading aggressively in Southern South America. Using niche analysis distribution models (SDMs), we examined requirements of D. using climatic, topographic, biological variables. We compared the realized United States (US) with Chile. Within Chile, also environmental conditions...
The genus Carpobrotus N.E.Br. comprises between 12 and 25 species, most of which are native to South Africa. Some species considered among the damaging invasive in coastal dune systems worldwide. In their introduced areas, these represent a serious threat significantly impact soil conditions geochemical processes. Despite being well studied, taxonomy remains problematic, as complex that hybridize easily difficult distinguish from each other. To explore population genetic structure (i.e., C....
Premise of the Study Knowledge about introduction history (source(s), number and size events) an invasive species is a crucial prerequisite to understand invasion success facilitate effective sustainable management approaches, especially for biological control. We investigated Australian legume tree Acacia dealbata in South Africa. Results this study will not only provide critical information Africa, but also broaden our overall knowledge on ecology globally important tree. Methods used...

Abstract Knowledge of the introduction history and spread dynamics invasive species can provide important insights for management (Ens et al. in Environ Rev (in press), 2022), however such information is often unavailable accidental introductions. Here we infer how European shore crab, Carcinus maenas , its congener, Mediterranean C. aestuarii were introduced to within South Africa. We do this using nuclear microsatellite data Bayesian assignment tests Approximate Computation (ABC) modelling...
Myotis atacamensis is a poorly known bat species endemic to the central portion of pacific coast South America, where it from province Lambayeque, Peru (latitude 5° S), Elqui 30° Chile. Here, we report first record M. for Choapa 31° S, Coquimbo Region) in This southernmost within Chile and extending its geographic range ca. 200 km southward.
To understand the success of invasive alien species, it is necessary to evaluate site-specific eco-evolutionary challenges they face in their new environments. We explored whether rearrangement genetic diversity linked invasiveness Prosopis juliflora by (i) comparing different stages invasion (founding vs populations) two invaded areas (Afar Region, Ethiopia and Baringo County, Kenya) are dominated attributes (e.g., characteristic genotypes or levels diversity) (ii) evaluating if landscape...
Results from studies to improve mass rearing production of the parasitoid Aphytis melinus De Bach (Hymenoptera: Aphelinidae) are presented. Parasitoid was carried out following standard commercial procedures using an alternative host, Aspidiotus nerii Bouché (Hemiptera: Diaspididae), infesting Cucurbita moschata (Duchesne) (Cucurbitaceae), butternut squash. We found that initial number A. adults introduced into cages start and scale/parasitoid ratio in those profoundly influenced future...
