A novel typology of social-ecological regime shifts, applied with respect to different case studies of landscapes dominated by non-native acacias.

‘Regime shifts’ — a useful concept on which to base discussions about impacts of biological invasions?

What happens when you take a concept developed to describe elements of ecology and apply it to complex social-ecological phenomena involving politics, economics, culture, and more?

A framework for engaging stakeholders on the management of alien species

As conflict of interests around alien species can prevent the success of management actions, an international team of researchers and managers, including C·I·B researchers, have recently developed a 12-step framework for engaging stakeholders on the management of alien species.

Social-ecological impacts of two invasive plant species in eastern Africa

Findings from two recent papers by C·I·B postdoc, Ross Shackleton, highlight how the invasive plants prickly pear (Opuntia stricta) and Lantana (Lantana camara), cause negative impacts on local communities and the environment in Kenya and Uganda.

Negative effects of Siam weed invasions for Tanzanian livelihoods

Findings from a paper by a C·I·B post-doctoral fellow, Ross Shackleton, highlight how a recent invader, Siam weed (Chromolaena odorara), has significant negative impacts on the livelihoods of local communities and the environment in Tanzania.

Read more about the article Connecting ecosystem services, disservices and plant invasions
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.
