Citizens meet coral gardening

12 10 2021

It is possible to cultivate corals in the sea like growing a nursery of trees to restore a burned forest. Cultivated corals grow faster than wild corals and can be outplanted to increase the healthy area of damaged reefs. Incorporated in projects of citizen science and ecotourism, this activity promotes environmental awareness about coral reefs, the marine ecosystem that is both the most biodiverse and the most threatened by global change.


When I finished by undergraduate studies in the 1980s, I met several top Spanish marine biologists to prospect my first job ever in academia. In all one-to-one interviews I had, I was asked what my interests were. And when I described that I wanted to study ways of modifying impacted marine ecosystems to restore their biodiversity, a well-known professor judged that my proposition was an inviable form of jardinería marina (marine gardening) ― those words made me feel embarrassed and have remained vivid in my professional imagination since. Neither the expert nor the young researcher knew at the time that we were actually talking about ecological restoration, a discipline that was being formalised exactly then by botanists in their pledge to recover pre-European conditions for North American grasslands (1).

Aspects of coral gardening. The photos show (top) a diver scraping off (with the aid of a toothbrush) algae, sponges and parasites that compete for light and nutrients with the coral fragments under cultivation along suspended ropes (Cousin Island, Seychelles), (middle) coral outplantings in the Gulf of Eliat (Red Sea) hosting a diverse community of fish that clean off the biofouling for free (21), and (bottom) a donor colony farmed off Onna (Okinawa, Japan) (12).

Today, the term coral gardening encompasses the suite of methods to cultivate corals (tiny colonial jellyfish with an external skeleton and a carnivorous diet) and to outplant them into the wild to boost the growth of coral reefs following perturbations (2). In the face of the decline of coral reefs globally, due to the combination of climate change, pollution, and overfishing (3), this type of mariculture has gathered momentum in the last three decades and is currently being applied to more than 100 coral species in all the main reefs of our seas and oceans (4-6).

Smoothing over content issues with co-author agreements

7 10 2021

I’ve written before about guidelines for co-authorship that I’ve formulated after years of accrued hit-and-miss experiences. Here, ‘hits’ refer to positive experiences (thankfully, the majority), and the ‘misses’ obviously refer to those times where co-authorship had become a contentious issue. While guidelines can go a long way to reducing the probability of nasty in-fighting occurring, there is never a water-tight approach that can avoid all problems.

However, the more I delve into multidisciplinary research that covers potentially controversial subjects, the more preparation for combatting future points of contention becomes necessary. What do you do when different specialists contribute material to a paper with which some other co-authors don’t necessarily agree?

Yes, this conundrum is real, and potentially flies in the face of the standard statement (and their variants) needed for most journal submissions these days:

All authors contributed to the article and approved the submitted version

Note, however, that the statement almost always includes the word ‘approved’ rather than ‘agreed with’. A subtle difference, I know, but it’s an important one.

This is where a pre-submission ‘Co-Author Agreement’ comes into play. Until quite recently, I have only ever prepared one such a document before, and that one was not terribly comprehensive.

But I’ve recently been working with a large, multidisciplinary group of specialists for which an official Co-Author Agreement made a lot of sense.

What is a Co-Author Agreement? It’s essentially a contract that prospective co-authors sign prior to submission of the manuscript to a journal so that potential disagreements can be dealt with more officiously down the track.

I looked for templates online and found a few that were suitable, and then modified it to our specific conditions.

I thought it might be a good idea to pass along a generalised template for a good Co-Author Agreement that you can modify according to your needs. I’ve broken down the content into sections:

Avoiding a ghastly future — The Science Show

1 10 2021

Just thought I’d share the audio of an interview I did with the famous Robyn Williams of ABC Radio National‘s The Science Show.

I’d be surprised if any Australians with even a passing interest in science could claim not to have listened to the Science Show before, and I suspect a fair mob of people overseas would be in the same boat.

It was a real privilege to talk with Robyn about our work on the ghastly future, and as always, the production value is outstanding.

Thank you, Robyn and the ABC.

Listen below, or link to the interview directly.
