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.”

Scientists at Sea Podcast – Sail Against Plastic Part II

Show notes

You might remember that earlier in the series we spoke to Flora Rendell and Lowenna Jones about an arctic sailing expedition they were about to embark upon in 2018 titled ‘Sail Against Plastic’. Well they’ve been there, done that, and got the microplastic samples to prove it. If you didn’t catch the episode, I would recommend having a listen to it here.

The Sail Against Plastic team – Photo credit – Ben Porter

In short, Sail Against Plastic was a two-week multidisciplinary research expedition taking place in the waters off Svalbard. Sailing aboard the Blue Clipper, the team investigated the impact of plastics and noise pollution on this arctic environment whilst producing film, photography and artwork to capture the experience and illustrate their findings. You can find out about the background of the expedition on the Sail Against Plastic website.

This time Flora is joining us with Daniel Osmond, with both of them being greatly involved in the scientific aspect of the expedition. Since recording they have both gone on to secure PhDs, well done to both!


“It was just a great example of how different people with different experiences, interests and skill sets can all come together”

Scientists at Sea Podcast – Microplastics and Sharks with Kristian Parton

Show Notes – Mircoplastics and Sharks with Kristian Parton

 

Of all the pollutants impacting the environment, plastics are perhaps among the most talked about and campaigned against in recent years. We’ve had members of Sail Against Plastic on the podcast before to discuss the presence of plastics in some of the most remote areas of ocean, but in this episode we take a look into how some plastics penetrate further – the invasion of food web ecology by microplastics.

 


 

Kristian Parton 

As an undergraduate with the University of Exeter, Kristian developed a strong interest in

marine conservation, specifically elasmobranch (shark and ray) ecology and biology. After being involved in several shark conservation projects around the world, from Mozambique to the Philippines, Kristian went on to start his current research as a Master by Research post-graduate investigating plastic ingestion in several North-East Atlantic shark species; Tope, Dogfish, Smooth-hound, Bull huss and Spurdog. The project aims to investigate whether diet and foraging behaviour has an influence on the consumption of micro plastic, and its accumulation within the digestive tracts of these species.

 


 

Is it a dog? Is it a fish? No, it’s a shark…

Kristian’s research has a broad focus on several small to moderate shark species found in the waters of the UK and North-East Atlantic, most of which are unknown to the wider public – all too often over-shadowed by larger, more cinematic species. The most common species that Kristian works with is the Lesser Spotted Dogfish…or the Small Spotted Catshark…or some may say the Murgey (Scyliorhinus canicula). Whatever you wish to call it, this species exhibit beautiful spotted patterns on a pale body, and are a delight to see in the wild for those lucky enough to spot them among the kelp beds. Though regularly caught in numerous trawl and gill net fisheries, they are not often eaten among Cornwall, though are put to use as bait while Kristian claims a few from local fishermen for science. The exact status of their stocks is unknown though they are thought to be fairly numerous and common. Unfortunately, this is not the case for many of the other sharks that Kristian samples.

For more information on the fisheries of S. caniculla, and other shark and/or marine species click here.

 


 

Fake Plastic Seas 

With so much plastic floating around, there is no surprise that it finds its way into the food webs of marine ecosystems. Our news feeds are battered by reports of stranded marine animals whose stomachs are littered with plastics, clips of animals mistaking plastic bags for their primary food sources, and new studies quantifying the presence of micro-plastics in almost all areas of nature. The problem is more than just full bellies of unnatural content, which in of itself is a great concern. Studies have shown that plastics may contain chemical traces that can disrupt systems by which organisms regulate and produce hormones, leading to further and exacerbated biological implications.

To find out more, have a listen to the episode.
