Knauss in Aberdeen – Biodiversity in the Best and Worst of Times


The World Conference on Marine Biodiversity is well underway in Scotland and Knauss fellows have been feasting on the wealth of knowledge and information shared by researchers and resource managers from all over the globe.  As the hub for fishing and shipping activities and the oil and gas capital of the United Kingdom, Aberdeen (affectionately termed the Granite City) is an appropriate venue to hold discussions about the importance of conserving marine biodiversity.  Aside from the classic principles of biodiversity being essential to ecosystem resilience and our very existence, experts are presenting on the impacts of climate change, coral genetics, economics, the role of Marine Protected Areas, and recent changes in policy and law.  One of the cornerstones of this conference is no doubt the recent successes and next steps of the ten year effort known as the Census for Marine Life (in case you missed the memo, they discovered a modest 20,000 new species!).  This and other themes has reminded me of the real immergence of interdisciplinary and international conservation work, which is often the most difficult yet most important to undertake for the marine environment. 

Aberdeen City Center
As can be expected, no meeting of biodiversity scientists and aficionados would be complete without those passionate for plankton and benthic invertebrates.  While sitting in one of these presentations on ocean productivity and biodiversity hotspots, I was reminded of the power of bottom-up trophic effects.  As it turns out, a research group in the UK has used biodiversity indices and ocean fronts to model coastal areas that are important for animals such as seabirds, sharks, and marine mammals (similar to our TOPP program).  Where there is more benthic invertebrate diversity and productivity, there are more forage fish, and therefore greater megafauna diversity and abundance. This model was confirmed by satellite tagging studies, where you can see how the foraging and migration paths of these large animals follow the formation of currents along continental shelves on a relatively short time scale.  This information can then be used to more quickly inform spatial planning or renewable energy development projects such as offshore wind farms.  This concept is complicated by the seasonal and variable nature of these ocean fronts, which the author cited as proof for the need for more flexible protected areas.  Talk about interdisciplinary!

Benthic foraminifera
One of highlights so far was a very inspiring plenary presentation by Jeff Ardon, director of the Marine Conservation Biology Institute.  By speaking very charismatically on the challenges in marine conservation in what Ardon refers to as the best and worst of times, he reminded us that local innovation and creativity must be applied at the global scale to minimize cheating.  Strong incentives to ignore the rules are crushing positive contributions of science-based management around the world.  Whether neglecting to report bycatch, releasing more than your fair share of greenhouse gases, or ignoring international protocols, cheating is rampant and dangerous.  Ardon reminded us that despite the great technological feats of our time, we still suffer billions of dollars in damages from Illegal, Unreported, and Unregulated fishing.  While local conservation triumphs are worthy of praise, it is daunting to step back and recognize the existing gaps in international management capacity. 
 
These thoughts have been an interesting start to a conference where scientists must lift their heads from the details of benthic microfauna genetics to ensure that we act more wisely by admitting what we don’t know yet not ignoring what we already do know. 

Tune back in for more updates as this conference proceeds!
