Is a Changing Environment Bringing Baby Bull Sharks to North Carolina?

Marine environments are typically considered more open than those on land when it comes to animal movement. On land, the range of a species can be limited by geographic features like mountain ranges, canyons, rivers, and anything else that might get in the way. In the ocean, however, actively swimming animals like, say, large sharks have few physical barriers and may instead be restricted by their own environmental preferences. This is why in unusually warm summers you might see tropical fishes in southern New England. Because of this, one of the anticipated consequences of warming ocean temperatures is shifting distributions of mobile and highly migratory species. Basically, changes in temperature are likely to allow marine animals to move into places they haven’t before, and if those temperature changes become consistent, these species might make regular visits or even just start staying there.

This kind of change is already happening and has been documented across a variety of marine species. Now, findings from a new paper in Scientific Reports by me and co-authors from the North Carolina Division of Marine Fisheries, Simon Fraser University, and East Carolina University show an apex predator may be joining the northward shift.

Nature Publishes Top 100 List for Ecology Papers. Here’s Why It’s Wrong.

This morning, I sat down at my desk to clear out my morning emails, make my to-do list, and go about my day. Through several of these channels, I was pointed to a new article in Nature detailing the top 100 articles every ecologist should read. There were already critiques of it flowing through social media, mainly about the representativeness of the list. Depending on which kind of professional hat I’m wearing at the moment, I tend to agree with these assessments. While I recognize – and have read – most of the papers on the list in my early ecological education, I think it misses the mark on defining ecology. Read More

The Worlds First Empirical ‘How-To’ Get Into Graduate School Book

Many years ago as a graduate student at the College of William & Mary, Virginia Institute of Marine Science, my former officemate (Noelle Relles) and I came up with a novel idea: take all the disparate information out there about strategies for getting into graduate school in the natural sciences and coalesce them into a single concise yet comprehensive text. Essentially develop a How-To book about graduate school. But we wanted the book to be more than just instructional anecdotes. We were scientist, and thought it would be useful to add a level of empiricism to the book. We wanted to write a How-To book where the conclusion were driven by results from a national survey of graduate admissions offices in the USA. At the time, writing a book based on a national survey of graduate programs seemed like quite a long-shot as we were both a number of years removed from getting our PhDs, and the most pressing issues in our lives at that time were graduating and finding free food and alcohol.

Scientific literature needs discipline – an example from a killer whale life expectancy study

If you let a puppy piddle on the carpet without discipline, it will keep doing it. It will grow into a big dog that destroys your carpeting and rugs and makes your whole house stink.

So it is with scientific literature.


We all know bad papers are out there. When you read them, you’re left scratching your head and wondering, “How on earth did these pass peer-review?” Worse still, there are “ugly” science articles, where the scientific method goes by the wayside and data are cherry-picked, misinterpreted or manipulated to justify a political or ideological agenda or to undermine science that interferes with that agenda.

Title is the new abstract

There are an increasing number of scientific articles being produced and posted at a frantic rate. How can you make your paper stand out and be memorable amongst this plethora of publications? Moreover, if your work is conservation-related, how do you ensure that the people who matter see and remember your work?

The one part of your paper all readers see and read is the title. From my own experience as an editor of scientific journals, as well as from the page-view statistics I have seen, the percentage of people that go on to read your abstract is less than a tenth of those that read the title. The percentage that read beyond the abstract to look at the whole article is a tenth of that again.

This why I have entitled this blog “Title is the new abstract“. You want to maximize the amount of information in the title of your paper.

The decline and fall of the literature review

I’m currently doing an annual review of environmental impacts on whales and dolphins for the International Whaling Commission, which involves assessing, reading and potentially summarizing almost everything that’s published on cetacean conservation. Every year this exercise gives me an ulcer because: (a) climate change and pollution threats are accelerating; (b) reiterated recommendations from scientists from many, many previous years have yet again gone unheeded; and (c) some endangered species get closer and closer to extinction, yet most of the funding goes to research questions whose answers we really already know rather than to practical conservation. It’s all rather depressing …

So you’ve been asked to review a manuscript? – Tips for the novice reviewer

Review a manuscript

Any scientist who is trying to publish relies upon the generosity of other scientists to peer-review their work. As any scientist will tell you, this has pros and cons – constructive advice can greatly improve a manuscript and fix flaws, but on the cons side every scientist has stories about the infamous “reviewer #3” who makes every scientist’s life hell at some time or other. As you start to build a name for yourself, you’ll be asked to review manuscripts, and you should! Reviewing manuscripts is an essential task for any academic and is an integral part of academic life – it is basically an obligation. But there is generally no class on “how to review manuscripts” despite it being a critical part of an academic’s job, and the reviewer has a huge responsibility: your review could potentially make, or seriously hamper, someone’s career. Moreover, doing a poor job reviewing could let bad, unscientific research get published, or even prevent important research getting accepted. To help navigate the minefield of reviewing, here are some tips and suggestions for the novice reviewer…
