Laboratory research will never be a substitute for fieldwork

A recent opinion piece published in Science (Minteer et al., 2014) titled “Avoiding (Re)extinction” has re-sparked an argument on the collection of specimens to confirm a species’ existence (see press release here). The authors argued that in lieu of killing and collecting the animal, photography, audio recording, and nonlethal sampling methods could be applied without increasing the extinction risk of endangered animals or newly discovered species. Social media discussions on Twitter and Ecolog-L listserve alerted me to two rebuttals which argue that this piece will only fuel anti-collecting sentiments espoused by a subset of people who don’t understand how research, scientific collecting and taxonomy work.

For an extensive view of the many problems with the authors’ argument you can read here and here. For the purpose of brevity suffice it to say that museum collections have a unique value and that the suggested nonlethal sampling methods are rarely possible and/or effective to document and understand species with reasonable confidence and therefore implement successful conservation plans.

If established scientists can make such asinine statements in such a popular journal I wondered if such ignorance and scientific-illiteracy could lends itself to the fieldwork I’m doing. Certainly one of the major impediments to research today is technophilia and a reduction in funding (Bury et al., 2006). I liked Bill Nye’s decision to engage in public debate with the creationist Ken Ham (not because I’m disillusioned that he will change his mind – he won’t) because I also believe it’s more important than ever to have an environmentally literate society.

So, is it really necessary to study animals in their natural environment? Could you not breed animals and study them in the laboratory rather than collecting threatened or endangered individuals from the wild? Certainly the advances in technology have enabled more work to be done in the laboratory than ever before. Sitting at a laboratory bench oblivious to nature outside you could devote an entire career to coral polyps alone and still make great contributions to science. However, this only scratches the surface. The genus sclearactinia is the product of many episodes of microevolution and interactions with other organism in the natural environment and very little at the molecular and cellular level makes sense until it has been placed inside this broader framework.

Certain scientists, like Jeremy Fox, vehemently champion artificial natural systems, like microcosms, because they can reduce the complexity enough to make it easier to solve ecological riddles in a controllable, replicable and cost-effective manner. However, these systems deal with protists which are very, very tiny and can be done in a glass mason jar. To scale this type of experiment up for corals would be very expensive; indeed, field studies are often the cheapest option for PhD students because there is no infrastructure or maintenance costs involved. The corals I study are broadcast spawners and only spawn once a year. That’s not much data, and certainly not enough for a thesis. So I do use a surrogate system in the laboratory (the sea anemone Aiptasia pallida), a somewhat well know species because it can be induced to spawn monthly giving me more data to analyze. However, these organisms are more distantly related systematically and ecologically. So to answer questions about coral definitively the work needs to be on corals and it needs to be geographically representative (McCallum and McCallum, 2006).

It’s important that we study these intriguing animals now because environmental stressors frequently influence life history characteristics early in the stress response (Newman and Unger 2002). It’s important we undertake these studies now in a “healthy” environment to potentially save them before they disappear from the biosphere.

Climate Change and Corals: Laying Siege to the Adaptation Mythos

This is my rebuttal to the recent blog by Jacob Jerome a Graduate Student and Intern at the University of Miami in the RJ Dunlap Marine Conservation Program titled “Climate Change and Corals: is it too late?”

Dear Mr. Jerome,

While I’m envious of your glass half-full outlook on the fate of corals to global warming, I feel that your only helping to propagate a persistent mirage; namely that *all* coral individuals or communities will adaptively respond in time to thermal stress. As will be argued here, this removes the onus of implementing a global strategy that can reduce both local and global stresses and implies that we have more time with respect to the pressures on coral reefs and related ecosystems.

Climate change is a major threat with rising sea surface temperatures and ocean acidification acting as chronic stresses which operate over long timescale. Implications include many adverse effects, bleaching, reduced growth and reproductive outputs, death and loss of biodiversity (Loya et al., 2001; Fabricius, 2005; De’ath et al., 2012). Thermal stress could potentially also increase viral load and corals susceptibility to disease. If we stopped emissions today, much of the warming would persist for centuries after greenhouse gas emissions stopped. If the current rate of emissions holds (business-as-usual), or increases, the ability of corals to respond evolutionarily to the rapid pace of change is doubtful (Dove et al., 2013).

Although evolutionary history is complicated by cyclical climate changes over geologic time (Vernon, 2000), coral reef system have changed as a result of climate change with few contemporary reefs existing in a “pristine” state. Most long-term studies show declines of around 50% since the early 1980’s. During this period coral composition has changed with the dominance of species being altered as well. By comparing recent events of decline to those of the past indicate that current rates of changes are orders of magnitude higher than they have been for tens of millions of years. You mentioned in your article that according to the Status of Coral Reefs of the World: 2008, 15 percent are seriously threatened. However, more recent studies looking across the world’s coral reefs, 75% are threatened (Burke et al., 2011). I’m not of the “coral reefs are doomed” prophecy point of view but I do believe that the situation is dire and that returning reefs to a pristine condition is not a realistic goal. Although I’m not suggesting we abandon all hope and toss in the towel (after all I’m not entirely a curmudgeon because then why would I even bother with the work I do?), I just think we need to be careful, and to tread lightly, when communicating as major funding agencies are often evaluating whether or not to continue funding coral reef management and management-related research.

Studies documenting recovery have yielded mixed conclusions. Some authors have proposed that individuals, or indeed communities, can adaptively respond to thermal stress (Logan et al., 2014). However; the broader scientific community has concerns as to whether Scleractinian (reef building species) will survive global warming and ocean acidification (Baker et al., 2008; Vernon et al., 2009; Hoegh-Guldberg, 2014). I think this is especially important for blog posts which are aimed at the broader public. We need to be clear about internal disagreement within the ivory towers for such contentious, and politically sensitive topics such as climate change. This has played out vividly in the past in such instances as “climategate”. As scientists we should leave ample room in our communications to highlight the dissent and nuances to complex topics in a way that the general public will recognize and think critically about.

I felt that you spun a one-sided story, in that you only included the exceptions to the rule rather than covering the wider accepted literature on reef resilience and adaptability. Most studies incorrectly extend the evidence which is necessary but not sufficient to support the conclusions that coral reefs will survive due to their ability to acclimatise, adapt and/or migrate to the current rapid environmental changes (Hoegh-Guldberg, 2014).

A couple of points I would like to address critically are as followed:

  • You mentioned the study by Raina and colleagues (2013) and suggested that this was evidence that this is a “fight” against temperature shifts? I fail to see how you can jump to such conclusions when juvenile corals were only exposed to elevated temperatures for 12 days. Moreover, adult colonies of A. millepora exposed to 32°C for 10 days had an 84% reduction in their Symbiodinium. To me, there findings only suggest a stress response which likely plays some role as an anti-oxidant in cellular processes. The loss of biodiversity in coral and symbiodinium following bleaching, added to increased probability of consecutive bleaching would suggest a loss in reef cover and diversity if current trends continue (Stat et al., 2006). The authors posit that release of DMS, as a result of bacterial conversion of DMSP, could be a major source of cloud condensation nuclei. However, I feel that your readiness to extrapolate and say that it would offer some sort of adaptive advantage is a far-reach by any estimate. Especially since the authors acknowledge that the declining trend in coral cover due to anthropogenic stressors can further destabilize local climate regulation.
  • Second, you mention the Cayman island recovery in 7 years as investigated by Manfrino et al. (2013). While I appreciate seeing findings which are contrary to common assumptions I think we need to take them with a large grain of salt. I would be the first to point out that in Samoa corals can thrive in 35°C water for a few hours each day, a “fact that they’re there means they’ve adapted to survive says Steve Palumbi. However, I believe this is an isolated case, and therefore not representative of the coral reefs by-and-large. Similar statistics have engendered debates about the value of marine protected areas (Huntington et al., 2011). We need to be honest by not omitting inconvenient truths, this is what it means to be a scientist, instead of say a lobbyist or philosopher. Johnson and Saunders (2014) suggest that demographic and economic factors influence the psychology of human decision to such a degree that it has a major impact on local ecology. The work they did in Curacao and Bonaire showed that socio-cultural-economic backgrounds influence marine resource management approaches which likely has an effect on the local ecosystems resilience and recovery. Curacao’s economy primarily relies on fishing (making money by exploiting resources), whereas Bonaire’s economy relies more heavily on revenue from tourism (making money by preserving resources). The Cayman Islands are therefore not representative of the vast majority of countries which harbor coral reefs (and rely on a subsistence economy) and it is unlikely that this study is representative of the broader global coral reef ecosystem.
  • Thirdly, you believe that “new scientific research indicates that not all corals are quite ready to give up”. I agree with you to the extent that this is true as in the case of Samoan corals or Dubai in the Arabian Gulf. Nonetheless, at what cost to the ecosystem if only a few corals, or communities, can survive? Massive plating and encrusting morphologies have been shown to be less susceptible than branching morphologies in a broad range of habitats, biogeographic regions and sea warming events (Loya et al., 2001). It has been shown that the rugosity of the substratum is positively correlated with observed fish species richness in most reports (Gratwicke & Speight, 2005) so a loss of substrate complexity could be bad news in a warming world.

One more thing to consider is symbiodinium clade changes, as algal symbionts are thought to play a key role in coral resistance and resilience. At the risk of not keeping my rebuttal germane (I know you never mentioned this, likely for the obvious reasons I’m about to bring up) I should mention another contentious issue as it relates to adaptation. Its alluring to think that hosts may switch/shuffle symbionts (Buddemeier & Fautin, 1993) for ones that may be more tolerant to the changing environmental conditions; this would overcome the slow pace of coral host evolution (a consequence of long generation times and low population diversity due to asexual reproduction). However, Lewis and Coffroth (2004) have shown that the octocoral Briareum only takes up symbionts that are found in normal conditions which does not represent the uptake of completely new symbionts to that host species. This suggest that the adaptive potential of corals may be limited to the existing types of symbionts present in the host. A number of authors have presented convincing data which suggests that few hosts have more than one type of symbiont (Baird et al., 2007), generalist corals such as Acropora and Pocillopora have a high flexibility, while specifist corals such as Porites have a low flexibility to symbionts diversity. Moreover, corals which harbor clade D are more thermo-tolerant, but the coral fitness may suffer energetic costs such as a reduction of growth and reproduction (Jones & Berkelmans, 2011). I think the paucity of evidence of propitious effects such as coevolution in the literature requires further investigation.

Due to the large policy implications I feel that your post should set a higher standard of demonstrating results beyond a reasonable doubt, or at the very least recognizing that scientists are split over this issue. I’m worried that certain subsets of the public will cherry pick results and trumpet “scientists prove reef extinction is not occurring”. After all there are those with a vested interest who will pervert fact and take things out of context. Others, such are media reporting may just skim right over this and not do background research on the actual papers referenced. In my own humble opinion the belief that somehow corals will magically evolve into a resilience state and alter the current trajectory of coral reef ecosystems under rapid anthropogenic climate change is a dangerous pipe-dream indeed.

Inside a coral nursery

Tanks
Here is a behind the scenes look at coral propagation at the Husbandry Center of Taiwan’s National Museum of Marine Biology and Aquarium (NMMBA). This facility is used for a wide variety of purposes including culturing of live foods, isolation of new animals, breeding area, nursery environment for animals born here, medical care for animals that may need it as well as the propagation of corals – the latter will be focused on in this post.  You could call this a coral farm, parent colonies are maintained and continue to grow in this facility, and the branches of these colonies are propagated by fragmentation – similar to the way new plants are grown from cuttings of existing plants.

The fragments -or ‘frags’- are affixed to a base, soft corals are sewn onto terracotta tiles (15 x 15 cm), on the rugose side as they prefer surface irregularity. As the frags grow, they will attach themselves and encrust onto the base structure and start to develop several branches.
Coral_Spats

After reaching a larger size they can be put into tanks inside of plastic planter pots.

Hard coral frags on the other hand are suspended in tanks by monofilament lines. When they are big enough they can be epoxied to a hard substrate.hard_smallHard_Large

Why should we grow corals when wild-harvested corals are available right out the front door of the Museum?  It’s our social responsibility to reduce the pressure on the world’s coral reefs.  Every coral fragment we can grow in the facility is one less taken from a natural reef.

At NMMBA coral propagation is used for Aquarium as well as the natural products research they do here. Around 2008 they did a study to see if they should undertake restoration efforts; however, they found that recruitment was high enough that they did not need to. Unfortunately, this is not the case globally and a number of agencies in various other countries are involved in these operations. Frags are attached onto natural live rocks using cyanacrylate glues, which will eventually, naturally, establish their foothold on the live rocks.  Restoration efforts began in the 1970s-1980s (Maragos 1974, Harriot and Fisk 1988) and have been increasingly implemented in the Caribbean targeting threatened staghorn coral, Acropora cervicornis (Lamarck, 1816) and elkhorn coral, Acropora palmate (Lamarck, 1816), which were once the dominant reef-building taxa in the region.  Due to the combination of biological and human induced stressors, Acropora has suffered significant degradation with estimated population declines of up to 95% in some areas (Porter and Meier 1992) leading to their listing as threatened in the US under the Endangered Species Act in 2006 and as critically endangered in the International Union for Conservation of Nature (IUCN) Red List of Threatened Species in 2008.

Although a number of projects are now getting significant funding, using considerable technical expertise and field efforts to establish coral nurseries, and plant out small colonies, the success is varied. While there is a lot of news about how well corals do in the nursery there is little evidence of long-term success once planted out. However, the University of Miami researchers report 92% survival of all outplanted corals since 2007.  Frame1frame2

Other critics of these efforts mention that selection of “resistant” corals are ones that survive in the nursery. The coral reef restoration project Dr Sarah Frias-Torres is running in the Seychelles is a bit different. During the 1998 massive El Nino, which coincided with the Indian Ocean Dipole (the “Indian El Nino”), about 97% of the shallow coral reefs in the tinner granitic island died. This project uses frag from the 3% that survived the massive coral bleaching. This means, they are not growing corals that survive in the open ocean nurseries, but are growing fragments of the corals that survived a major warming event. There is hope that the restored coral reef will have a better chance of survival this time.

Indeed, some doubt that such efforts will be successful, for example these so called “artificial reefs” are often displaced by hurricanes and typhoons (Vize, personal communication). Wave heights can exceed 10m and can move steel frame boxes (average height 5m) lashed together with steel cable that are attached to steel beams and concrete bridge pilings functioning as anchors can be displaced up to 1200m (Turpin and Bortone, 2002). However, it depends on how these structures are installed. Reef Balls is a non-profit and international environmental NGO that has deployed over 1/2 million artificial reefs, which have been noted to have not been displaced by Hurricane Georges in 1993 (Harris, 1998).
ReefBall

In the past 5 years coral nurseries have expanded to ecologically meaningful levels and are beginning to have a considerable impact on the localized recovery of coral reefs (RinkevichForrester et al., 2014). I’m aware the pie of conservation dollars is small and we don’t want to see any slices going into ill-conceived projects that promise restoration with no solid scientific support. Nonetheless, I think we can make the pie bigger, involve public and private sources of funding while working at the same time in science-based conservation and science-based restoration.

Curmudgeons are quick to point out that this is only a local approach (and costly at that) and will not be an effective long-term solution. Sadly, they may be right. As long energy production continues to release C02, oceans will continue to suffer. Nonetheless, in many coral tourism and coral aquaculture areas, including the Maldives, Thailand, Indonesia, Philippines and some Pacific Island States, etc, there are many sound commercial reasons why resort companies and other commercial ventures should and do support local coral nursery and plant-out projects, and personally I support this type activity.

Investigating Circadian and Circalunar Systems in Cnidarians

578764-coral-spawning-at-ningaloo-reefOur lab is particularly interested in how broadcast-spawning in corals is temporally regulated, and how solar and lunar illumination control the time at which spawning occurs.  Perhaps the most well known synchronized spawning event is the mass spawning behavior of corals on the Great Barrier Reef where over a hundred species spawn within a few hours after sunset on the nights surrounding the full moon once a year.  The time (hour and minutes) of gamete release is directly controlled by sunset time and not an entrained clock (Brady et al., 2009; Levitan et al., 2011).  However, it has been suggested that the level of lunar irradiance could provide a cue to synchronize the night of spawning in cnidarians (Vize et al., 2012).

Circadian clocks allow organisms to anticipate environmental changes with seasonal cycles of day and night.  There are many similarities between the bilaterian and the cnidarian clocks suggesting that molecular components of the endogenous clock are highly conserved (Reitzel et al., 2013).  The potential that lunar illumination may interact with the circadian clock to set the date of spawning is still open to question. To address this issue we will exploit environmental, pharmacological and genetic means to test the interdependence of circadian and circalunar timekeeping.

Corals detect light via photoreceptors that alter signal transduction pathways, controlling the levels of second messenger calcium, which is responsible for entraining light-driven circadian rhythms. When Hilton et al. (2012) treated coral larvae kept in the dark with thapsigargin, a compound that raise the level of cytoplasmic calcium, patterns of proteins shifted to a day pattern. Melatonin has been found in all multicellular animals, including the cnidarians (Anctil et al., 1991),where a circadian pattern of production was observed (Peres et al. SICB 2012). My working hypothesis is that light induced calcium inhibits melatonin production, and that low levels of melatonin production in response to the full moon set the spawning date, which occurs as night time illumination tapers off. Pharmacologically altering night time melatonin levels in coral and anemones should generate the same responses as the phase of the moon.

The field of cnidarian circadian biology provides an opportunity to test the hypothesis on roles of circadian clocks regulating physiology as well as the evolutionary conservation of circadian regulatory pathways. Spawning synchrony is a complex phenomenon dependent upon the physiological response to several environmental cues which vary both spatially and temporally. By experimentally manipulating cycles of lunar illumination and molecular pathways (using thapsigargin and melatonin) will allow us to determine whether corals display circalunar transcription cycles or if circadian cycles intersect with lunar illumination in some other fashion.  If our results demonstrate circadian and circalunar rhythms are responsible for setting the spawn date, management during lunar cycles prior to spawning will be essential. Findings could potentially encourage researchers to focus on the development of mitigation measures in areas of high risk. This may include monitoring and limiting run-off and human activities such as artificial illumination during period prior to spawning.

Does Monsanto have the Midas Touch: “Golden Rice” a golden opportunity or false hope?

Monsanto’s newest GM crop, golden rice, masquerades as a philanthropic venture -to alleviate vitamin A deficiency in third world children- and is paraded as a “silver bullet” technology.   It has the backing of the Bill and Melinda Gates Foundation, Helen Keller International, the Rockefeller Foundation and the U.S. agency for International Development. 

Who could possibly object to such a “good” cause.? 

I was outraged to read UKs environment Secretary Owen Paterson’s rhetorical campaign claiming that opponents of third world GM crops are “wicked” and “disgusting”.  Like other hysterically unqualified defenses of rationality, this carries a worrying whiff of fundamentalism.  His recent comments have raised a unanimous ire from the environmental movement community such as: Greenpeace, Friends of the Earth, ActionAid and other non-government organizations.   The fact that he went so far as to claim that “these protests will be condemning millions of people to a premature death” is nothing short of spin doctoring.  Even more concerning is the editorial that the journal Science published makes a series of highly dubious claims and that some of its authors have links to GM companies – of course this conflict of interest was not stated in the editorial.  There not alone, the globe and mail is also spreading misinformation.

Sure, Monsanto WILL be helping children but at the end of the day they are an agricultural/biotech company so the interest lies, not in sound science or sick children but, in the bottom line.  The best way to make money is control the market and before you can do that you need to convince people that there’s something else at stake. Sarojeni Rengam, executive director of Pesticide Action Network Asia, has said: “Golden rice is really a “Trojan horse”; a public relations stunt pulled by the agribusiness corporations to garner the acceptance of GE crops and food.  The whole idea of GE seeds is to make money.”

GM Bt cotton and seed monopoly has a created a context for debt, suicides and agrarian distress which is driving the farmers’ suicide epidemic in India; one farmer every 30 minutes commits suicide.  Farmers must borrow large sums of money to invest in GM technology. They do so based on promises that yields will increase and profits will soar. But when the promises fail to pan out and farmers are unable to keep paying for the expensive pesticides, they typically end up losing everything, including access to reusable heirloom seeds. So, many end up killing themselves because they literally have nothing left.  Through patents on GM products Monsanto sues farmers and traps them in debt, while the PR machinery spins tales of improving farmer’s welfare, and the deception that GMOs feed the world (the real issue here is global population; a contentious issue that no one seems to want to talk about).  Monsanto’s talk of “technology” tries to hide its real objectives of ownership and control over seed where genetic engineering is just a means to control seed and the food system through patents and intellectual property rights.

Let me tell you a little story about a product that Monsanto made over 50 years ago: Agent Orange.  Sure it was never marketed to save children -in fact quite the opposite, if they had advertisements it would have been like this– but I bring this up for one reason, and one reason only: accountability.  Although Agent Orange was only used for a decade its effects persists to this day.  That is, three generations of exposed Vietnamese families and American veterans suffering from horrific birth defects and disabilities.  Monsanto and Dow contaminated the land of Vietnam, destroyed the forests, killed, maimed, and crippled millions of people, but never admitted responsibility or paid a cent in compensation to the victims and their families.  As Baron Thurlow once said about corporations “[they] have no soul to save, no body to incarcerate”, we saw this with the financial-crisis where virtually every major bank and financial company on Wall Street destroyed trillions of dollars of the world’s wealth and nobody went to jail.  If golden rice gets the go-ahead Monsanto stands to gain immensely, they will happily reap profits and if anything went wrong people it will be PEOPLE paying for it for untold generations and… nobody goes to jail.  I’m sure positive Monsanto would get off the hook and little, if any, reparations would ever be made.

I believe the most moderate, ethical and scientific view in SUPPORT of golden rice is that of Professor Huw Jones, research group leader at the Center for Crop Genetic Improvement at Rothamsted: “There are three key issues: Is it safe? Is it effective? And will there be informed choice in the grower/consumer communities?  If the answer to all is yes, then it is a no-brainer that golden rice should be part of the solution to malnourishment in Asia.  The field trials must be done and let’s let the local communities decide.”  Clearly here, the greatest assets are skepticism and democracy.  We need to use due diligence to investigate this before we go ahead.  In the meantime, furthermore instances of power-play (like Mr. Paterson’s) specifically designed to evaporate people’s normal critical faculties is a kind of extremism that airbrushes out alternatives and attempts to deny the space not only for discussion, but even for imagination.
