Tiny, symbiotic organisms protect corals from predation and disease

Corals could have some unexpected allies to cope with the multi-faceted threats posed by climate change.

In a new study published today in Proceedings of the Royal Society B, Montano and colleagues show how tiny hydrozoans smaller than 1 mm and commonly found in dense colonies on the surface of hard corals (see above photo) play an important ecological role.

Visually examining ~ 2500 coral colonies in both Maldivian and Saudi Arabian reefs, the scientists searched for signs of predation, temperature-induced stress, and disease. For each colony, they also recorded the presence of symbiotic hydrozoans. They demonstrated that corals living in association with hydrozoans are much less prone to be eaten by corallivorous (i.e., ‘coral-eating’) fish and gastropods than hydrozoan-free corals.

A likely explanation for this pattern could be the deterring action of hydrozoan nematocysts (cells capable of ejecting a venomous organelle, which are the same kinds found in jellyfish tentacles). An individual hydrozoan polyp of less than 1 mm clearly cannot cope with a corallivorous fish that is a billions of times larger, yet hydrozoans can grow at high densities on the surface of corals (sometimes > 50 individuals per cm2). This creates a sort of a continuous, ‘urticating‘ carpet that can discourage fish from foraging. Read the rest of this entry »

Giving a monkey’s about primate conservation

Saving primates is a complicated business. Primates are intelligent, social animals that have complex needs. They come into conflict with humans when they raid rubbish bins and crops, chew power cables, and in some cases become aggressive towards people.

Humans, however, have the upper hand. While 60% of non-human primate species are threatened, humans grow in numbers and power, building roads through forests, hunting and trapping primates, and replacing their habitat with farms and houses.

To help primatologists choose the most effective conservation approaches to resolve these problems, researchers in the Conservation Evidence project teamed up with primate researchers to produce a global database on the effectiveness of primate conservation solutions. This free database, which can also be downloaded as a single pdf, summarizes the evidence for 162 conservation interventions — actions that conservationists might take to conserve primates. The data come from searches of over 170 conservation journals and newsletters, and each study is summarized in a single paragraph in plain English, making it possible for conservationists without access to scientific journals to read the key findings.

Front cover primate synopsisSo what works in primate conservation? Well, the picture is rarely straightforward — partly due to the lack of data — but there are some interesting trends. Reducing hunting is one area where there seem to be a range of potentially effective approaches. Community control of patrolling, banning hunting and removing snares was effective in the three studies in which it was tested, all in African countries.

Further emphasizing the importance of involving local communities, implementing no-hunting community policies or traditional hunting bans also appeared helpful in boosting primate numbers. In other places, a more traditional approach of using rangers to protect primates has proved a winning strategy. Training rangers, providing them with arms, and increasing ranger patrols all worked to protect primates from poachers. Identifying the circumstances in which community led approaches or ranger patrols work will be key to implementing the most appropriate response to each conservation challenge.

Research in Translation

11 12 2017

Do you enjoy the challenge of communicating complex scientific ideas and conservation issues to the general public? Current Conservation is looking for submissions of reader-friendly summaries of recently published research papers in conservation science!

Current Conservation is a quarterly magazine that communicates conservation science in an accessible manner to a wide audience. Our magazine combines art and science to communicate the latest in research concepts and news from both the natural and social science facets of conservation, encompassing ecology, wildlife biology, conservation biology, environmental history, anthropology and sociology, ecological economics, and related fields of research.

Your summary (~ 250-300 words) should be written in a simple jargon-free way that conveys the nuances of the paper, but at the same time is easy and fun to read. You can find some examples here.

Ecologists are gender-biased

16 11 2017


I normally don’t do this, but this is an extra-ordinary circumstance.

As many of you are already aware, Franck Courchamp and I published a paper in Nature Ecology and Evolution on Monday that ranked high-profile ecology papers. I won’t go into any details about the list here, because you can read the paper and the associated blog posts themselves.

The publication caused a bit of a stir among ecologists, evidenced by the rather high and rising Altmetrics score for the paper (driven mainly by a Boaty McBoatface-load of tweets). I haven’t done any social-media analysis, but it appears that most of the tweets were positive, a few were negative, and a non-trivial proportion of them were highly critical of the obvious male-biased nature of the list (in terms of article authors).

On that last point, we couldn’t agree more.

Which is why we have a follow-up analysis specifically addressing this gender bias, but that’s currently in review in Nature Ecology and Evolution.

In the meantime, however, and at the suggestion of possibly one of the coolest, nicest, and most logical editors in the world, Dr Patrick Goymer (Editor-in-Chief of Nature Ecology and Evolution), I’ve just posted a pre-print of our paper entitled “Gender-biased perceptions of important ecology articles” on bioRxiv.

100 papers that every ecologist should read

14 11 2017


If you’re a regular reader of, you’ll be used to my year-end summaries of the influential conservation papers of that calendar year (e.g., 2016, 2015, 2014, 2013), as somewhat subjectively assessed by F1000 Prime experts. You might also recall that I wrote a post with the slightly provocative title Essential papers you’ve probably never read back in 2015 where I talked about papers that I believe at least my own students should read and appreciate by the time they’ve finished the thesis.

But this raised a much broader question — of all the thousands of papers out there that I should have read/be reading, is there a way to limit the scope and identify the really important ones with at least a hint of objectivity? And I’m certainly not referring to the essential methods papers that you have to read and understand in order to implement their recommended analysis into your own work — these are often specific to the paper you happen to be writing at the moment.

The reason this is important is that there is absolutely no way I can keep on top of my scientific reading, and not only because there are now over 1.5 million papers published across the sciences each year. If you have even the slightest interest in working across sub-disciplines or other disciplines, the challenge becomes more insurmountable. Finding the most pertinent and relevant papers to read, especially when introducing students or young researchers to the concepts, is turning into an increasingly nightmarish task. So, how do we sift through the mountain of articles out there?

It was this question that drove the genesis of our paper that came out only today in Nature Ecology and Evolution entitled ‘100 articles every ecologist should read‘. ‘Our’ in this case means me and my very good friend and brilliant colleague, Dr Franck Courchamp of Université Paris-Sud and the CNRS, with whom I spent a 6-month sabbatical back in 2015.
