Unhappy feet – why we need more than a day of penguin awareness

January 22, 2015February 13, 2015 Chris Parsons 1 Comment

A couple of days ago (20^th January) was penguin awareness day¹. But do we really need to be more aware of penguins? Well, actually yes.

We conducted a study a couple of years ago (pdf also available) to look at public awareness of penguins (using university students as a sample) and found that nearly half (43%) of those questioned though that penguins were protected under the US Endangered Species Act (ESA) and were thus listed as “endangered.” At the time only one penguin was listed on the ESA (the Galapagos penguin, Spheniscus mendiculus). The IUCN currently classifies five species of penguin as “endangered”² and six as “vulnerable”³. The biggest threat to penguins generally is, unsurprisingly, climate change. The chicks of Magellanic penguins (S. magellanicus) in Argentina have experienced increasing mortality because of increasing numbers and severity of storms, and will continue to experience mortality as these further increase, in addition to additional mortality from increasing rainfall and temperatures. Changing patterns of sea ice cover are impacting Adelie penguin (Pygoscelis adeliae) foraging at Ross Island, Antarctica. In various locations in the Antarctic Penninsula in particular, Adelie colonies are expected to be impacted by warming temperatures and changes in sea ice with perhaps as many as 75% of colonies decreasing or declining. Although in some locales, melting ice has increased potential Adelie habitat. Chinstrap colonies have been reported to be in decline as well, despite this being a more open water species, that was previously being thought of as potential benefactors from melting sea ice – penguin nest occupation on Deception Island declined by more than third between 2002/2003 and 2009/10. These chinstrap penguins are likely being impacted by declining krill stocks, as will their Adelie penguin cousins, in addition to ice loss which so affects this latter species. Overall, across the Antarctic Pennisula, there has been a decline in both Adelie and chinstrap penguin numbers.

Many scientists, conservationists and fishermen support our trophy fishing paper recommendations

Last month, a team of marine scientists (which included Andrew and I) published a paper pointing out that intentionally killing the largest and most fecund members of IUCN Red List Threatened species is not a good thing and could be easily stopped (by stopping record awards entirely for these species or moving to a catch and release model)

Our recommendations were not universally supported by scientists, and we received criticism from respected colleagues largely in the form of “this isn’t a particularly big problem, no serious people care about it.” There was also an official response from the IGFA to this effect, which we issued an official response to. Sure. It isn’t the biggest problem in the world, but it is a problem. And you’d be hard-pressed to find a conservation problem that’s easier to solve.

A petition created by the Blue Planet Society based on our recommendations has, as of this writing, surpassed 6,000 signatures from all over the world, including many from scientists, fisherman and professional conservation activists. The paper has also been widely discussed on social media

Presented here are some quotes from scientists, fishermen and conservationists supporting our recommendations. While this support does not inherently mean that the issues we raise are important, it certainly shows that lots of serious people care about it.

Sizing Sizing Ocean Giants: Patterns of #scicomm outreach in a marine megapaper

Blogging, Conservation, Science

Last week, Craig McClain and many friends published Sizing Ocean Giants: patterns of intraspecific size variation in marine megafauna, a research paper that would better be described as a monograph. The response to the paper has been overwhelming.

Since it’s publication last Tuesday, Sizing Ocean Giants has been viewed almost 44,000 times by 38,000 people and downloaded 1200 times. If this seems like a lot for what is essentially a natural history monograph, you are correct. According to Altmetric, a service that measures the non-citation impact of scientific papers, Sizing Ocean Giants is the most discussed and shared article in the history of PeerJ. With a score of 546 (most papers average a score of 5, PeerJ papers average about 20), our paper has climbed into the 99th percentile of all articles ever tracked.

We’ve been covered in the Washington Post, Newsweek, National Geographic, and Scientific American, as well as numerous non-English media outlets from Mexico to Greece. Opa! We’ve seen a small attention spike on twitter and tons of shares (almost 12,000) via Facebook.

So how do we account for the huge success of this massive paper?

Six things I learned about Giant Isopods while Sizing Ocean Giants

Today, Craig McClain, along with a massive team of ocean scientists (including me!) published our monumental paper: Sizing ocean giants: patterns of intraspecific size variation in marine megafauna. This massive monograph investigates patterns of size among 25 ocean giants, the biggest, most massive members of their respective taxa. You can probably guess which species I had a hand in reviewing.

Along the way, I learned quite a few cool things about the magnificent giants of the deep sea.

An open letter to new Discovery Channel President Rich Ross from a shark scientist

Dear Rich Ross, new President of the Discovery Channel,

I was excited to learn about your commitment to no longer show fake documentaries on the Discovery Channel. These shows have been incredibly damaging not only to Discovery’s goals of being the “number one non-fiction media company in the world” by”telling compelling and accurate stories,” but to public understanding of science and conservation. In recent years, the Discovery Channel has tried hard to actively muddle the fact that these documentaries were fake, including hiding vague disclaimers at the very end. I’ve spoken to hundreds of schoolchildren about sharks, and every time someone asks me about megalodon or mermaids. Viewers believed that they were real, and your channel actively bragged about the fact that people believed that they were real.

By claiming that megalodon isn’t extinct and mermaids are real but the government is covering this up, these shows resulted in scientists receiving threats and harassment, and resulted in important government agencies getting so many angry phone calls that they had to issue public statements. Producers for some of these shows intentionally lied to scientists to convince them to appear onscreen, intentionally lied to journalists about the facts behind them, and intentionally caused a real-life public panic. They actually showed a documentary about a legendary (read as “fake”) shark called Hitler. In short, I will be glad to see Shark Week and the Discovery Channel return to your roots of fact-based programming.

However, while “we won’t actively lie to viewers anymore” is an important step that I applaud, Shark Week and other Discovery Communications programs have many other problems that should be addressed. Shark Week 2014’s “Zombie Sharks” glorified wildlife harassment for no reason, as the entire stated goal of the show was for a non-scientist with a history of wildlife harassment to try to answer a question that scientists have known the answer to for decades. This problem is not limited to Zombie Sharks, but pervades Discovery Communications shows.

Snowy Owls and Goliath Groupers: Why I co-authored “Trophy fishing for species threatened with extinction.”

In both my professional and private life, I am a man who wears many hats. I am a deep-sea ecologist, a science writer, a goatherd, a geneticist, a conservation advocate, a grill master, and many others. When David asked me to join him in co-authoring “Trophy fishing for species threatened with extinction: A way forward building on a history of conservation” I did so not in my capacity as a marine science Ph.D., but as a recreational fisherman who cares deeply about the survival of his sport. Without fish, there is no fishing.

I was, at first, skeptical, but over the course of a summer, I came to appreciate what David was trying to accomplish.

I wrote most of my thesis on this boat, with a rod in the water.

Before I talk about fish, I need to talk about birds.

The era of the million-dollar tuna is over.

For the last several years, we’ve been following the first-of-the-year Tsukiji Tuna Auction. In the past, this auction has served as a (often questionable) benchmark for the demand for Bluefin Tuna. At its peak, the price of Bluefin Tuna broke the scales at nearly $1,800,000. As the price continued to inflate, last year we even released an early warning to journalists covering the auction, cautioning them against drawing too many conclusions about the expectedly massive auction price. We we’re all caught off guard when the price of the first fish barely topped $70,000 dollars, kilo-for-kilo not even the most expensive fish sold that day.

Today, the numbers are in, and the first Bluefin of the year sold for a measly $37,500, barely enough to cover the cost to fuel for a fishing boat.

The era of the million-dollar tuna is over.

In a cave in the Lonely Mountain there lived a dragon. Not a gnarly, goblin-stuffed, slimy cave, filled with the bowels of orcs and fishy creepers, nor yet an empty, granite, echo-less cave with nothing in it to lie down on or horde: it was a dragon-cave, and that meant gold. At least it did, until a nasty band of poachers found Lonesome Smaug, the last of his species, alone, asleep, threatening none, and smote his genus from the red ledger, stripping Middle Earth of critical biodiversity.

The ecologists of Carsondell would say, of the age of war that followed, that the men and dwarves and elves and hobbits brought the darkness upon themselves. Indeed, as the Dark Lord raised his army, denuded the forests, and belched carbon from the factories of Mordor, Gandalf the Grey, one of the more powerful, though among the least conservation-minded, of the wizards would remark: “It has been said that dragon-fire could melt and consume the Rings of Power, but there is not now any dragon left on earth in which the old fire is hot enough.”
