Blue nodes represent core authors, green- newcomers joining during and after 2011, red-authors left network before or during 2011, and yellow-authors with once off involvement in 2011. Link colour represents when links were formed. Wider links are indicative of a higher frequency of co-authorship. Black links were established between 1997-2004, grey-2005-2011 and red-2012-2017. Triangular nodes represent continuant authors in the 2004 peak. Links between red nodes and their neighbours represent ties that were established and then severed over the 1997 to 2011 period. The more articles co-authored by an author the larger the node (see Abrahams et al 2019).

The role of core researchers in shaping collaboration networks and research futures

Improving our understanding of the role researchers play in forming collaborative networks, can allow for more effective administration of the network to maximise research benefits. This includes the increased integration of knowledge across disciplinary boundaries, increased research productivity and innovation.

Refining the distribution of co-occurring invasive sportfishes and their hybrids

Multiple species of black bass (a collective term that refers to members of the genus Micropterus, including Largemouth Bass Micropterus salmoides and Florida Bass Micropterus floridanus) have been introduced into southern Africa and form the basis of an important recreational fishery.

The worldwide invasion of the Asian long-horned beetle

Repeated introductions from both the native and the invaded ranges of a major tree pest, the Asian long-horned beetle (Anoplophora glabripennis), has enhanced its establishment and spread. These were some of the findings of a paper recently published in the journal Molecular Ecology.

Read more about the article Assessing lizards’ vulnerability to warming: how close should we zoom in?
To measure the habitat temperatures available to Girdled Lizards (left), the study’s authors used 'operative temperature models' (right). These models were hollow copper replicas of the lizards, with a temperature sensor inside that was connected to a central data logger. By mimicking the thermal properties of live organisms in the absence of physiological function, these models can accurately predict the temperature that a live organism would experience in the same location.

Assessing lizards’ vulnerability to warming: how close should we zoom in?

Climate data are increasingly accessible and are being used to predict which species are most vulnerable to climate change. The available datasets often consist of monthly measurements or predictions for locations every dozens or hundreds of kilometres. Can such coarse data provide realistic vulnerability assessments for small organisms?

Mexican sunflowers are harmful to rural African farmers

Mexican sunflowers (Tithonia species) are promoted as a green manure, but a survey of rural farmers revealed that these species are invasive, and have substantial negative impacts in addition to their benefits.
