In a recent review published in the Transactions of the Royal Society of South Africa, a diverse team of researchers led by C·I·B postdoctoral fellow Heidi Hirsch compiled comprehensive information on the past and current status of river red gum (Eucalyptus camaldulensis Dehnh.) in South Africa.
New species are introduced to environments outside their native ranges, sometimes causing negative ecological and socio-economic impacts. Identifying which species are potentially problematic is important in planning strategic responses for preventing introductions and mitigating impacts in vulnerable environments such as cities.
Guava (Psidium guajava L.) is a commercially grown small tree, which also invades pastures and abandoned fields in South Africa. The tree acts as a pioneer species in recovering degraded landscapes thus making ecological restoration a challenge.
A recent study by Fahimeh Jami, together with C·I·B researchers Jaco Le Roux and Dave Richardson, had a closer look at the geographical and host range of Botryosphaeriaceae, a family of fungi that are common pathogens on woody plants. The study, published in the journal, Fungal Biology, provided the first Botryosphaeriaceae records for both the locations and hosts studied.
Guttural toads (Sclerophrys gutturalis) have been invasive in Mauritius and Reunion for nearly 100 years (since ~1922), and have been in Constantia (near Cape Town) for another 20 years, but where did those colonising toads come from?
