Sunset Seminars: Crustacean Evolution & Ecology
2 June | Speaker: Prof George Branch
Sunset Seminars is a series of free monthly talks presented by experts on various topics in the Old Conserve Music Hall. In this session, Prof Branch draws on modern science to explore the ecological impacts of crustaceans—from rock lobsters to barnacles—and the marvels of genetic research.

Whole new worlds have opened with the development of modern ecological experiments, methods of observation, and genetic studies. In this talk, Prof Branch will draw on the wonders of modern science to speak about two major things: firstly, the ecological impacts of crustaceans and, secondly, the marvels of what genetic studies have unraveled about crustacean evolution and the role of crustaceans in our world.
Ecosystem Functioning
He will discuss research that his laboratory has been involved in concerning the impacts of rock lobsters on ecosystem functioning. Rock lobsters are one of South Africa’s most important marine resources and are pivotal in controlling ecological communities. He will also discuss more humble crustaceans such as amphipods and barnacles and their profound role in ecosystem dynamics.
The Genetic Mystery
As a second part of the talk, he will use crustaceans as an example of the truly mind-blowing genetic research that has thrown light on their evolution and relationships. Crustacea are among the most diverse of all animal groups. How they achieved this has for a long time been shrouded in mystery: but the mists are now lifting thanks to genetic studies, and the extraordinary ‘inventiveness’ of crustaceans is slowly becoming understandable.
Scientific Admiration
Part of the talk will focus on his admiration for crustaceans and how astonishing their diversity and ecological effects are. But it will also focus on his admiration for the inventiveness of the human mind in the range of scientific approaches that are being explored to unveil the wonder of crustaceans.
Booking Information
Although talks are free, visitors will be required to book in advance. These talks are hosted on weekday evenings in the Old Conserve Music Hall next to the Botanical Café.

The Stellenbosch University Botanical Garden's three main goals are to promote conservation efforts, academic support, and education.
The Stellenbosch University Botanical Garden is frequently used as an open-air laboratory and plant material from the Botanical Garden is regulary used in various practicals.
Education has always been a part of botanical gardens – often being associated or established with universities in the area. At the Stellenbosch University Botanical Gardens, we strive to make a difference in the lives of those that live, learn and work in the area by providing an experience that not only reconnects people to nature but teaches them about its wonders. Therefore, a few different educational tour options for registered educational facilities have been prepared to facilitate this. Tours can be booked by contacting the garden via phone or email. For pre-booked registered groups, no entry will be charged. Prior booking is essential. Educational tours have been prepared to correspond with the CAPS school curriculum.
Intermediate and Senior Phase (Grades 4-9)
This tour involves discussing things from what makes something alive to the water cycle and plant respiration. The tour will be shaped to the specific group, considering the majority grade present. We hope to inspire and bring things learnt in the classroom to life, helping them engage with topics in a relevant way that invokes the valuing of the natural world.
These tours will typically take under 1 hour.
F.E.T. Phase (Grades 9-12)
There are many different learning styles and, for some, the best way to learn is to experience and see, smell, and feel things for themselves! This tour is designed to be supplementary to high school biology and help make theory a little more tangible and colourful. We will discuss things like the different classification systems of life to biomes and ecology all the way to hormonal plant defense mechanisms. We boast a beautiful conservation collection, an indigenous medicine and food garden as well as an invasive plant display – all helping the knowledge learnt in the classroom come alive. Tours can have highlighted topic areas if desired, but this is not necessary.
These tours will typically take around 90 minutes (about 1 and a half hours).
Visiting University Groups
We love collaboration and invite any travelling academics to contact us directly to organize a personal tour with our curator or assistant curator.
Things worth taking note of:
- School learners enter for free when part of a pre-booked group.
- Take note of the weather and warn learners before the time to prepare appropriately.
- It helps provide a more insightful tour if we have ample warning to prepare, be sure to book well in advance to ensure this.
