Hybridisation, Competition and Predation: threats to one species of Xenopus from another

The most recent assessment suggests that the Cape platanna is Endangered, but that instead the decline being fuelled by habitat loss, it is now the threat from hybridisation, competition and predation by the African clawed frog.

The authors found that more alien species with the potential to establish are likely to be introduced to Durban than to other South African ports. One such a species that is not yet in South Africa that could be introduced to Durban through high risk shipping routes, is the disease vector, the southern house mosquito (Culex quinquefasciatus).

Reducing the number of invasive species introduced through shipping

Research conducted by C·I·B post-doctoral fellow Katelyn Faulkner demonstrates that to reduce invasions, ships travelling along high risk routes should be targeted for inspections.

Global insect invasions are difficult to predict from distribution models alone

Non-native invasive insects have major impacts on ecosystem function, agricultural production and human health. To make better predictions of where such species may establish and invade, species distribution models (SDMs) are widely used tools to predict potential distributions and invasion extents across new geographical areas.

Hakea sericea is an example of an invasive plant providing both services and disservices. This shrub or small tree in the protea family is native to Australia and was introduced in Portugal for afforestation goals. It is currently used by local people in Portugal to provide fences (an ecosystem service), but it also causes physical injury to people (an ecosystem disservice) and reduces recreation opportunities (reduced ecosystem service).

Connecting ecosystem services, disservices and plant invasions

A paper published in the journal Ecosystem Services presents a new classification of ecosystem disservices and a framework for integrating ecosystem services and ecosystem disservices for human well-being linked to ecosystem functioning.

Scoring environmental and socio-economic impacts of alien plants invasive in Europe

Using the Generic Impact Scoring System (GISS) can be a helpful tool for managers to identify invasive alien plant species with high environmental and social impacts.
