Avian influenza update, Alaska

Several years ago, Dan Gibson and I published a paper on Asian birds coming to North America through Alaska entitled “The Asia-to-America Influx of Avian Influenza Wild Bird Hosts Is Large.”  In this paper we reversed the conclusions of a popular model of the global spread of highly pathogenic avian influenza (HPAI). We suggested that wild birds are a greater risk than domestic poultry for bringing HPAI into North America. Since then, our model proved the more accurate, presaging the arrival in North America in fall 2014 of a pure Asian strain of H5N2. Wild birds were implicated, and we inferred passage through Alaska. This strain of HPAI went on to cause the worst poultry disease outbreak in U.S. history, resulting in billions of dollars in economic losses.

Migratory birds bring avian influenza to North America via Beringia

Our paper is out this month in the Journal of Virology pointing to the importance of Beringia in the intercontinental spread of avian influenza.

Trends in positions in research collections

In the research museum business, especially in the biological sciences, we’ve long been seeing declines in the number of positions being filled. This is something to be worried about because a) we have a lot to learn about biodiversity still, b) we’re losing said biodiversity at an unprecedented rate, and c) collections need to continue growing because they document so many important aspects of the environments we humans depend on. It’s not like other disciplines in research museums are getting fat at the expense of those disciplines losing positions; it seems to be an industry-wide phenomenon. Vicki Funk of the Smithsonian Institution recently posted an article outlining the dire situation in botany at a global scale.

On the other hand, the rising U.S. economy seems to have opened up a number of new vacancies, leading Michael Ivie of Montana State University to write an email to TAXACOM entitled “What A Great Time to be a Young Systematist”, using his observations of openings in entomology. I agree with Mike from an ornithological perspective: there are a relatively high number of positions opening up this year. Mike’s message has generated a long discussion, however, probably because we recognize that the numbers, while relatively high, are still very small in relation to the magnitude of the issues. In short, a long-declining trend is showing a brief halt and upward bump — and we all hope that collectively at least we see the decline stop and that perhaps we even regain some of those historic losses. There certainly is plenty of work to do, both in traditional biodiversity pursuits and in the new ways that collections are being used to study changes in diseases, contaminants, populations, and environmental and climatic changes.


Super Pato shows advantages of whole-organism sampling

Increasing the scientific bang for every research dollar spent is important, especially in museums, where funding levels are perennially low. When we do get into the field and get our hands on a bird, it costs about the same to bring it home with us as it would to return with just a few drops of blood or a couple of feathers. While there is little difference in the initial cost, there is a huge difference in the scientific potential of the effort’s product: many more scientists can do a lot more things with a whole bird preserved as a specimen than with only a tiny sample likely to be quickly depleted. And the vast majority of bird populations can easily withstand the relatively small amounts of scientific collecting that are done these days.

(Re)affirming the specimen gold standard

A recent opinion paper in Science by a group of authors more concerned with human ethics than with science and biodiversity used a rather broad brush to paint scientific collecting in a negative light. Perhaps through their lack of intimate familiarity with biodiversity science, they made a number of errors in their effort to urge field biologists to stop collecting voucher specimens. Setting aside the issue of why a prestigious journal like Science would publish what is a rather weak contribution, the appearance of this piece does provide an opportunity to again help people understand why scientific collecting is important, why it does not pose a threat to populations of wild organisms, and why in a time of global change adding specimens to collections is now more important than ever. There is a substantial body of peer-reviewed literature on this topic; I will just summarize some of the main points here.

An avian Jonah experiment

The UAM Bird Collection is used for a lot of interesting research, and we always enjoy the resulting products, especially when researchers push back the frontiers of human ignorance in new and important directions. In this case, some researchers (see Haynes et al. 2013) arrived on the scene at the bitter end (for the birds) of what we might call an avian Jonah experiment. Yes, birds were swallowed by a whale. We were sorry to learn that, unlike Jonah, the birds did not live through the experience, but instead emerged later, much the worse for wear, from the wrong end of the whale.
