Exeter Marine Podcast: Becoming Marine Biologists – with Lauren Henly, Emma Weschke and Tim Gordon

This episode was recorded back in early 2019. Ben talks to Lauren Henly, Emma Weschke and Tim Gordon, who are all masters by research or PhD students in Prof. Steve Simpson’s research group (you might remember Steve from an earlier episode, Coral Reef Bioacoustics Part I). The discussion focuses around the research they’re all undertaking, what got them interested in marine biology, and what they have done so far.

 


 

About our guests:

Emma Weschke

At the time of recording Emma was a masters by research student and is now undertaking a PhD with the University of Bristol focusing on coral reef fish ecology and bioacoustics.

Lauren Henly 

Lauren is a PhD student with the University of Exeter and Natural England studying functional ecology and behaviour of wrasse to inform management of wrasse fisheries. She provided us with the update below:

 “I’m now in the 3rd year of my PhD. I’ve been developing lots of different methods to assess the sustainability and potential impacts of the Live Wrasse Fishery on the south coast. I’m using genetics to look at the population structure of wrasse along the south coast so we can identify the most effective management unit size, using stable isotopes to predict the ecological impacts of the fishery, and working to ensure the views of other stakeholders (including recreational anglers) are considered when developing management measures for the fishery. It’s great being able to use such a broad range of techniques to address a key issue.”

Tim Gordon

Tim is completing a PhD with the University of Exeter and the Australian Institute for Marine Science focusing on coral reef bioacoustcs, what can you learn from coral reefs by listening to them. You can find out more about Tim’s work in a previous episode – Coral Reef Bioacoustics Part II.

  • Ecological consequences of marine anthropogenic noise on coral reefs, both during the day and at night.
  • How fish use underwater soundscapes.
  • Using underwater sound to aid marine conservation efforts.
  • The impacts of the degredation of coral reef marine noise
  • Using underwater speakers to make reefs louder.
  • The bigger picture aspects of working in a research group.
  • What got you into marine biology?

Scientists at Sea Podcast – Climate Change, why don’t people act? With Catherine Leyshon

Show Notes

In the last episode we spoke with Paul Butler and Annette Broderick about climate change and how this impacts their work on bivalves and turtles respectively. We also discussed some of the key points of the IPCC’s latest climate change report. If you would like to check that out, click here.

This time, we’re taking a slightly different approach in a chat we had with Professor of Human Geography, Catherine Leyshon. Specifically, we discussed the reasons why, in the face of overwhelming evidence, we appear to do very little in response.

The discussion ranges from why people might struggle to make small, every day changes, right through to governmental/international levels.


“We’re not really set up as a society to reward good behaviour, we tend to sanction bad behaviour”


Why don’t some actions work?

This seemed like a good idea in principle, but ultimately didn’t work out, we’ve collected a few pieces relating to this. You can read about what the taxes were, what impact they had, why they were abandoned, and what has happened as a result:

What was the emissions tax?

“Australia records biggest emissions drop in a decade as carbon tax kicks in”

“Australia abandons disastrous green tax on emissions”

“Australia’s greenhouse gas emissions soar in latest figures”

 


What actions might work?

Shifting Shores

In the UK we are seeing some changes. For example, the National Trust have introduced their Shifting Shores project, where they will now be focusing on adapting to changes at their coastal sites, rather than trying to prevent change.

For those of us in Cornwall, Mullion harbour wall is a particularly relevant example, you can read about the challenges the National Trust have faced with this here.

In 2012, Catherine co-authored a paper going into greater depth about this, which you can find here: Shifting Shores: Managing Challenge and Change on the Lizard Peninsula, Cornwall, UK


As Ethan mentioned in the episode, we are seeing some other actions, such as: Dutch parliament to set target of 95 percent CO2 reduction by 2050. There are several other areas covered in the episode, but to find out more you’ll need to give it a listen!


You can also read the IPCC Climate Change Press Release in full here.


Associate Professor Catherine Leyshon:

Catherine is a human geographer whose work combines landscape ecology, social relations and climate change. Catherine’s work on climate change is interesting for many reasons, but one aspect that really makes it stand out is its focus on local communities here in Cornwall. Studies can all too often focus on the distant impacts of climate change, but numerous studies from Catherine help to highlight the potential changes occurring on our door step.
