A big good luck to Saskia Thomas who heads off to Germany to represent South Africa in the international climbing competition arena, before heading to 3+ months of fieldwork in Zambia!

 


July 2017

John attended the recent 16th international symposium on insect-plant relationships SIP2017 meeting held in Tours, France in July to give a keynote lecture on insect responses to climatic variability. It was a productive and stimulating visit, with several fascinating discussions with various folks on insect microclimates and climate change responses on plants! It was also a super opportunity to catch up with some old friends, but also to finally get to meet researchers whose work I read regularly and are producing superb papers, but have never actually met in person!

Matt Hill’s recent paper was highlighted by the Centre for Invasion Biology:

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. – Read more here

In collaboration with Prof. Susana Clusella-Trullas (Department Botany and Zoology, SU) and Prof. Marshall McCue (St Mary’s University, Texas, USA), John helped co-organize a one-day ‘Stable Isotopes in Invasion Biology’ workshop that was attended by 35 post-graduate students from several institutions across South Africa, hosted by the Centre for Invasion Biology.

“The group of enthusiastic participants who attended the “Stable Isotopes in Invasion Biology” workshop hosted by the CIB in December 2016. The workshop was led by the expertise of Prof. Marshall McCue (St. Mary’s University, Texas, USA) and organized by Prof. Susana Clusella Trullas (CIB and Department of Botany and Zoology) and Prof. John Terblanche.”

April 2016

Prof. John Terblanche hosted an international IAEA workshop at SU in April 2016 on methods and techniques for dormancy management of insects in his Applied Physiological Ecology Lab. Prof. Terblanche is actively involved in two separate IAEA-funded co-ordinated research programs (CRP) investigating novel approaches and methods for increased performance of laboratory reared insects for release in sterile insect programmes.

International researchers visiting the Department of Conservation Ecology and Entomology who participated in the IAEA insect pest dormancy management workshop in April 2016, hosted by Prof. John Terblanche.

 


April 2016

In a major advance for the understanding of insect invasions, a special issue in the journal Biological Invasions was published in 2016  (Guest editors: postdoctoral fellow Matt Hill, together with Prof. Dave Richardson (C.I.B) , Prof. John Terblanche and  Prof. Susana Clusella-Trullas (Dept of Botany and Zoology). A collection of 13 articles from a diverse group of national and international scientists working across different aspects of entomological and biological invasions highlights what makes insect invasions unique and where future research efforts should be focused.

August 2015

Prof. John Terblanche successfully completed a Canada-Africa Research Exchange Grant with Prof. Phil Matthews at the University of British Columbia which examined how insect’s sense and respond to ambient atmospheric gases (CO2, O2) by means of respiratory chemoreceptors. The exchange culminated in producing an authorative review on the evolution of insect respiratory gas exchange published in Advances in Insect Physiology . Read more here

January 2014

Well done to Elsje Kleynhans for having two papers published this past week – one from her Master’s research on tsetse and environmental variability and the role of phenotypic plasticity and the other from her PhD research on Eldana stalk borers which examines host-plant effects on thermal tolerance.


December 2013

The APE and CLIME labs did a great weekend away at Landroskop Hut in early December 2013.

Congratulations to Dr Leigh Boardman for completing her PhD and to receiving a very prestigious NRF post-doctoral scholarship.

Congratulations (and welcome) to Vernon Steyn who joins the lab to work with Kate Mitchell and I on dispersal genetics of invasive fruit flies. Vernon also won double funding from the CIB and NRF for his project.

Congratulations to Dr Kate Mitchell on receiving a very prestigious Claude Leon Foundation scholarship to continue her research on dispersal and thermal tolerance in South Africa for another 2 years.

Congratulations to Dr Matt Hill for securing a prestigious CIB post-doc scholarship to re-focus his research more on invasions and insects.

We have had a lab member get married: Well done Ruben!
