World Heritage Species

17 08 2014

horseshoe crabHaving just attended the Baker & Stebbins Legacy Symposium on Invasion Genetics in Pacific Grove, California, I have had a rare bit of leisure time between my book-writing commitments and operating in conference mode. It’s summer here in California, so I’ve taken the opportunity to read a bit of The New Yorker in my accommodation. It is indeed a pleasure to have these micro-moments of ‘leisure’ reading. As it turns out though, work subjects are never far from my mind as I do this.

So it interested me greatly when I read another fantastic article in the ‘Yorker about horseshoe crabs, and their precarious state despite having survived half a billion years on this planet. While I was generally interested in the science, biomedical applications, conservation and systematics of the species, what really caught my eye was the proposal to list them as a ‘World Heritage Species’.

A what? Never heard of that classification, you say? Neither had I. Not to worry though – it doesn’t exist yet. Read the rest of this entry »





A fairer way to rank conservation and ecology journals in 2014

1 08 2014

Normally I just report the Thomson-Reuters ISI Web of Knowledge Impact Factors for conservation-orientated journals each year, with some commentary on the rankings of other journals that also publish conservation-related material from time to time (see my lists of the 2008200920102011 and 2012 Impact Factor rankings).

This year, however, I’m doing something different given the growing negativity towards Thomson-Reuters’ secretive behaviour (which they’ve promised this year to rectify by being more transparent) and the generally poor indication of quality that the Impact Factor represents. Although the 2013 Impact Factors have just been released (very late this year, for some reason), I’m going to compare them to the increasingly reputable Google Scholar Journal Metrics, which intuitively make more sense to me, are transparent and turn a little of the rankings dogma on its ear.

In addition to providing both the Google metric as well as the Impact Factor rankings, I’ve come up with a composite (average) rank from the two systems. I think ranks are potentially more useful than raw corrected citation metrics because you must first explicitly set your set of journals to compare. I also go one step further and modify the average ranking with a penalty term that is essentially the addition of the coefficient of variation of rank disparity between the two systems.

Read on for the results.

Biodiversity Hotspots have nearly burnt out

10 07 2014

dying embersI recently came across a really important paper that might have flown under the radar for many people. For this reason, I’m highlighting it here and will soon write up a F1000 Recommendation. This is news that needs to be heard, understood and appreciated by conservation scientists and environmental policy makers everywhere.

Sean Sloan and colleagues (including conservation guru, Bill Laurance) have just published a paper entitled Remaining natural vegetation in the global biodiversity hotspots in Biological Conservation, and it we are presented with some rather depressing and utterly sobering data.

Unless you’ve been living under a rock for the past 20 years, you’ll have at least heard of the global Biodiversity Hotspots (you can even download GIS layers for them here). From an initial 10, to 25, they increased penultimately to 34; most recently with the addition of the Forests of East Australia, we now have 35 Biodiversity Hotspots across the globe. The idea behind these is to focus conservation attention, investment and intervention in the areas with the most unique species assemblages that are simultaneously experiencing the most human-caused disturbances.

Indeed, today’s 35 Biodiversity Hotspots include 77 % of all mammal, bird, reptile and amphibian species (holy shit!). They also harbour about half of all plant species, and 42 % of endemic (not found anywhere else) terrestrial vertebrates. They also have the dubious honour of hosting 75 % of all endangered terrestrial vertebrates (holy, holy shit!). Interestingly, it’s not just amazing biological diversity that typifies the Hotspots – human cultural diversity is also high within them, with about half of the world’s indigenous languages found therein.

Of course, to qualify as a Biodiversity Hotspot, an area needs to be under threat – and under threat they area. There are now over 2 billion people living within Biodiversity Hotspots, so it comes as no surprise that about 85 % of their area is modified by humans in some way.

A key component of the original delimitation of the Hotspots was the amount of ‘natural intact vegetation’ (mainly undisturbed by humans) within an area. While revolutionary 30 years ago, these estimates were based to a large extent on expert opinions, undocumented assessments and poor satellite data. Other independent estimates have been applied to the Hotspots to estimate their natural intact vegetation, but these have rarely been made specifically for Hotspots, and they have tended to discount non-forest or open-forest vegetation formations (e.g., savannas & shrublands).

So with horribly out-of-date vegetation assessments fraught with error and uncertainty, Sloan and colleagues set out to estimate what’s really going on vegetation-wise in the world’s 35 Biodiversity Hotspots. What they found is frightening, to say the least.

Don’t torture your readers III

23 06 2014

TortureIt has been quite some time since I did one of these kinds of posts (see Don’t torture your readers and Don’t torture your readers II). However, given how popular they seem to be, I have decided to do a follow-up post on grammar problems that I tend to see far too often in science writing.

COMPOUND ADJECTIVES: This is a particularly abused component of scientific writing. Although it’s fairly straightforward, I’m amazed just how many people get it wrong. Most people appear to understand that when an adjective (that’s a qualifier for a noun, just in case you are a grammarling) is composed of more than one word, there is normally a hyphen that connects them:

  • e.g., ’10-m fence’, ‘high-ranking journal’, ‘population-level metric’, ‘cost-effective policy’

If two or more adjectives are given in a row, but none modifies the meaning of the others, then it is simply a case of separating them with commas:

  • e.g., ‘a long, high fence’, ‘an old, respected journal’, ‘an effective, enduring policy’

However, if the compound adjective is composed of a leading adverb (that’s a qualifier for a verb), then there is NO hyphenation:

  • e.g., ‘an extremely long fence’, ‘a closely associated phenomenon’, ‘a legally mandated policy’

There are other instances when no hyphenation is required, such as when the qualifiers are proper nouns (e.g., ‘a Shark Bay jetty’), from another language such as Latin (e.g., an ‘ab initio course’) or enclosed in quotation marks (e.g., ‘a “do it yourself” guide). Note in the last example, without the quotations, it would become ‘a do-it-yourself guide’).

A quick way to recognise whether a compound adjective should be hyphenated is to examine the terminal letters of the leading word; if the leading component ends in ‘ly’, then it is likely an adverb, and so the compound should not be hyphenated (although watch for sneaky exceptions like ‘early-career researcher’!).

South Australia’s tattered environmental remains

State budget percentage expenditures for health, education and environment

South Australia State budget percentage expenditures for health, education and environment

Yesterday I gave the second keynote address at the South Australia Natural Resource Management (NRM) Science Conference at the University of Adelaide (see also a brief synopsis of Day 1 here). Unfortunately, I’m missing today’s talks because of an acute case of man cold, but at least I can stay at home and work while sipping cups of hot tea.

Many people came up afterwards and congratulated me for “being brave enough to tell the truth”, which both encouraged and distressed me – I am encouraged by the positive feedback, but distressed by the lack of action on the part of our natural resource management leaders.

The simple truth is that South Australia’s biodiversity and ecosystems are in shambles, yet few seem to appreciate this.

So for the benefit of those who couldn’t attend, I’ve uploaded the podcast of my slideshow for general viewing here. I’ve also highlighted some key points from the talk below: Read the rest of this entry »





Alliance of Leading Environmental Researchers and Thinkers

11 03 2014

ALERTIf you’ve been following this blog or my Twitter feed over the last few weeks, you’ve surely noticed a few references to A.L.E.R.T. – the Alliance of Leading Environmental Researchers and Thinkers. You might also have asked yourself, what exactly is ALERT, and is it something I should pay attention to?

Today’s post attempts to explain this new organisation, and hopefully convince you that the answer to the second question is ‘yes’.

Several months ago, a slightly cryptic e-mail from eminent conservation biologist, Bill Laurance, arrived in my inbox. It asked – what do you think of this logo (see associated image)? A few e-mails later and a couple of minor tweaks, and we ended up with what I thought was a pretty cool logo for this new ‘ALERT’ thing. It wasn’t until quite some time later that I finally understood what Bill was attempting to create.

Is ALERT a news aggregator, a blog, an advocacy group, a science-communication resource or a science-policy interface? Why, yes it is!
