Katie Feilen and Amy Sullivan Dragonfly team members and instructors Kevin Matteson, Katie Feilen and Amy Sullivan discuss the required readings for this discussion as well as their own research backgrounds.

Notable quotes:

“They turned out to be undercover police!” (while describing interactions with people during fieldwork in NYC) – Kevin

“Don’t even get me started on tropical tree biodiversity!” (describing tropical fieldwork) -Katie

We know that we don’t know how many species there are on earth but I am constantly surprised by how many new species we are discovering.” (breaking down Mora et al. article)- Amy

Amy Sullivan and Judy Metcalf Dragonfly team members and instructors Amy Sullivan, Judy Metcalf, and Kevin Matteson discuss the following readings for this discussion as well as their experiences with invasive species.

Notable quotes:

“When you have a small annual grass (cheatgrass) out West that is replacing shrubland and juniper woodland, that is pretty substantial structural change! – Amy

“The deliberately introduced zebra mussels to clear up the water not realizing the unintended consequences.” – Judy 

“… then he (Simberloff 2011) starts talking about beavers, and mussels, and things that change the physical structure of environments… when they do that they also change the nutrient cycles.” – Kevin

Ramana Callen and Kendra Cipollini Dragonfly team members and instructors Ramana Callan, Kendra Cipollini, and Kevin Matteson discuss the required readings for this discussion as well as their personal feelings about extinctions. We start off discussing extinct and endangered species including American Chestnut (functionally extinct), the Passenger Pigeon, and the Thylacine (Tasmanian Wolf; ). Enjoy!

Notable quotes:

“I always love the name of the Metatron study (long-term fragmentation study) in France… of course, it makes me think of Transformers.”  -Kevin

The title of this discussion was Extinction and its Consequences. The first two articles are really about Extinction and its Causes (Brook et al. 2008 and Haddad et al. 2015) and this last one is really about consequences (referring to Brashares et al. 2014 article about social conflict).” – Ramana 

“Lag times totally freak me out…” -Kevin

“That was the perfect segue … speaking of bleak! We know all about all these things that are causing extinctions. We know the four big players … The “evil quartet.” (talking about Brook et al. article) – Kendra 

“2+2 = 6” – Kendra (When referring to non-additive effects habitat loss, fragmentation, climate change and more) 

“Acorns and beechnuts have taken over that ecological role (American Chestnut) but they don’t produce as consistent food so the wildlife is different because you had this constant massive crop of nuts every year. So, yeah, I would have liked to see mature, old-growth American Chestnut dominated forest.” Ramana (talking about functionally extinct American Chestnut)

Katie Feilen and Shaukat Khan Dragonfly team members and instructors Katie Feilen and Shafkat Khan join host Kevin Matteson to discuss the following required readings for this discussion as well as local actions to combat climate change. We start off discussing Shafkat and Katie’s actions to increase awareness of climate change in Oxford, Ohio using art. Their work has resulted in a community exhibition at the Oxford Community Art Center and various other collaborations. If you want to jump ahead using the audio slider below, we start discussing the Chen et al. (2011) paper at about 14 minutes, Hoegh-Guldberg and Bruno (2010) at 37 minutes, and Scheffers et al. (2016) at 47:30.

Notable Quotes

“I always struggle with Nature and Science articles because they make them so short…And what is lost is data …  I like data, that is what I realize. I need data, I need numbers, I need to get down and dirty.” – Katie

“Climate change is not necessarily a single source, single variable, single message change. Its messing with the Earth’s climatic balance that has so many different levels of impacts. Yeah, I am glad we are reading these articles.” -Shafkat

“Only 5% of climate change studies are in marine ecosystems.” and “A warmer world would be a sicker world.” – Kevin (quoting the Hoegh-Guldberg and Bruno (2010) article)

Ramana Callan and Jeannie Miller Martin Dragonfly team members and instructors Jeannie Miller Martin and Ramana Callan join host Kevin Matteson to discuss the required readings for this discussion as well as thoughts on mainstreaming biodiversity. Towards the end of the podcast, Kevin talks about whether or not to plant exotic bamboo in his backyard. Turns out . Who knew?! If you want to jump ahead, we discuss the Redford article at 15 minutes, Mace and Norris at 31 minutes, and Kueffer et al. article at about 47 minutes.

Notable quotes:

“Everything we do in Dragonfly comes back to “What is the question”, “What is the question” “What is the question?” We have to consider, Is the question that we want to drive data for our paper or is the question that we want to create a change somewhere?” – Jeannie referring to Redford et al. 2015 article 

“Sometimes biodiversity and ecosystem services are almost used synonymously which is a big pet peeve… I love that they (Mace et al. 2012 article) make it clear how they are different.” – Kevin

“I never really liked the ‘rivet airplane analogy’ (of species loss affecting ecosystem stability). I like the Jenga analogy better where you are destabilizing this tower and the context of the rivets (location, etc.) affects what happens.” – Ramana  

“There is really no wrong answer when you are doing the right thing.” – Jeannie
