Working Vacation


It’s been a great month for me, here on the westcoast. I’ve been visiting friends, family, cat, car, etc. on Vancouver Island, and doing some canopy sampling while I’m here also. The project, called ABASS (Arboreal Biodiversity Across Spatial Scales), was initiated at the end of my PhD, and this year I went into the field to collect HoBo dataloggers and a few arboreal moss samples. So, it’s a working vacation of sorts. But it’s the kind of work that I love to do. Firstly, the field sites are some of the most spectacular in the world. And secondly, because it’s an area that I have a connection to, as a scientist, and also because it’s home and I have history here.

This year I visited three sites in Clayoquot Sound UNESCO Biosphere Reserve on the west coast of Vancouver Island, just north of Tofino, BC. This is ancient temperate rainforest, and canopy samples are collected from 60m Sitka Spruce trees of coastal estuaries.

Of the three sites (Sydney, Watta, Moyeha), the Sydney is my favourite; mostly for it’s pristine forests, amazing wildlife, and sheer isolation. It’s located 1.5 hours by boat from Tofino, and about 45 minutes north of the village of Ahousat, where the new national chief of the Assembly of First Nations was celebrated just last week. In the Sydney it’s just water, rock, trees and sky as far as you can see.

A typical day in the field started with collecting Blue and Huckleberries from around the camp site before canoeing off to the estuary. This year has been phenomenal for berries all over Vancouver Island, and the Huckleberries were the biggest I’ve ever seen. I work with a professional tree climber (Kev the arbornaut), who has climbed over an estimated 15,000 trees in his career (he stopped counting at 10,000). Our task is to climb 12 Sitka Spruce trees in each of the three watersheds, and collect dataloggers and moss samples for extraction of microarthropods (mainly mites). Climbing big trees, it always amazes me that they are just plants, related to a piece of celery or an African violet, and here I am clumsily climbing up them like an ant crawling up a blade of grass. At the top you can feel them sway in the wind.

Of course, also on a typical day in the field, you need to accept the good with the bad. Good parts were napping and swimming in the estuary, and watching a Humpback whale lunge feed for pilchards in the inlet for 4 hours, while we sat on the rocks, drinking beer and eating oysters. The bad parts were falling down and bashing my knee on the rocks in the dry riverbed, getting stung by a bee and having my whole arm swell-up to the point where I couldn’t bend my fingers, and stabbing myself with my pocket knife.

But, it’s almost time to wrap-up and return to Montreal. I’m anxious to get back into the lab and start some new experiments, play with moss, and see some new mites. We have at least one new addition to our lab starting sometime this fall, so it should be an exciting time in the Gonzalez lab as some people finish up their projects and new ones get underway.

I hope everyone had a great summer, and I’ll see you all soon.

Farewell to Albuquerque

Well, ESA isn't over, but the Gonzalez lab contingent is pulling out this morning, leaving the Friday sessions to hardier folks than we. And while the conference certainly felt like it was winding down tonight, ESA definitely went out with a bang.

Overall the last two days offered fantastic talks, with a particular emphasis on competition (especially among plants). Whole sessions were devoted to long-term data sets like the censused plots of Barro Colorado Island and more experimental set ups like Cedar Creek. While I definitely agree that there is much that can be learned from long-term study sites like BCI and Cedar Creek (indeed, much research would be impossible without them), I wonder as to whether there might also be a problematic side to such awesome resources as these. For example, I went to countless talks over the last two days about tropical forest dynamics, probably 90% of which were conducted on BCI. Now, it's not that BCI isn't an appropriate place to study, it's just that it seems to be the only place that is studied, which may lead us to accept idiosyncratic patterns of BCI as typical universal tropical forest trends. Similarly, it seems that so much of our knowledge on the effects of diversity on ecosystem functioning (representing another big chunk of talks I saw over the last two days) comes from Cedar Creek; and while it is an awesome study site, it seems dangerous to let just one experiment inform us so completely on a topic that is so important.

All that being said, it was one of the talks on BCI that caught my eye today, given by none other than Stephen P. Hubbell, who was at once lucid, clear, concise, and humorous. His talk also had me thinking about the nature of star power in science - as the lecture theatre was packed to the brim. People even took pictures of him. It was off the hook.

And on that note, a farewell to Albuquerque.

Dispatch from Albuqerque

The 94th annual Ecological Society of America meeting kicked off this Sunday with two, count them, two Gonzalez lab members in attendance. The theme for this year's meeting is "Ecological Knowledge and a Global Sustainable Society," and while there is some deal of murmuring that the theme is particularly ironic for a relatively isolated location that happens to be in a desert, the unique setting has inspired some interesting conversations on water issues and other elements of sustainability.

External to the meeting theme there have been some genuinely interesting talks in the desperately over-air-conditioned Albuquerque convention center. In particular over the last two days I have enjoyed an interesting special session calling for the emergence of a fully formed discipline of "warfare ecology" to address the unique and prevalent ecological challenges presented by war, and a symposium looking at interactions of ecological and evolutionary dynamics. Indeed, there have been a few shards of inspiration capable of piercing even my bitter and withered heart.

One thing that strikes me about a lot of the talks is the value of a charismatic study system, by which I simply mean a clear cut relationship to nature. I think it is a weakness of my talks, and indeed of many other theoretical talks, that they fail to sufficiently highlight the organisms involved, treating the model systems as abstractions unworthy of particular merit or attention. The problem strikes me as twofold: on one hand I think that such naturalistic exhibitionism keeps the audience's attention better than sheer theory, but also reminds us of the tendency for nature to act in idiosyncratic and contextual ways.

Of course, the talks are only half the conference. Come nightfall there are always interesting people to talk to, and you really never know who you'll end up eating with. Never have I talked to so many people from so many countries.

Albuquerque out.

Summertime

Here in the northern hemisphere summer is in full swing, and for people of my age that means one thing: weddings. This past weekend a science-friend and I attended the wedding of a mutual friend, who is a rising star in the world of acarology, so naturally we ended up seated at the table with a bunch of other scientists. What ensued bore some resemblance to a mini-conference, with light banter about our research, and how we knew Wayne. Nautrally this entailed a trip down memory lane to my undergrad (Wayne and I were labmates during my honours project), when summer meant something very different - it meant field season.



Back in my younger days field season was a big part of science for me. In my undergrad I made massive collecting trips across Alberta, Saskatchewan, and the North West Territories (camping out on some collecting trips, and jumping out of helicopters on others), and during my masters I visited many lakes to gather inocula for my outdoor mesocosm experiment. Aside from providing the chance to be outdoors, an element of field work that I think we all like, this active field involvement also allowed my data to have at least a sheen of ecological realism. Both of these reasons make the call of the field beguiling, almost irresistable. The trade-off, however (there's always a trade-off...), was that it can be incredibly hard to assign any kind of mechanistic explanation to the complicated, ecologically-relevant systems that we often study in the field.



As a result I now spend less time outdoors, less time invested in ecologically relevant systems, and more time with 125 mL erlenmeyer flasks and two species diatom systems. In terms of data, things are lost (like the realism), but things are also gained (explanatory power and control). The same is true on a personal level: I've lost the sheer fun of playing in the mud and paddling madly to get off a lake before the thunderstorm hits, but I've gained the ability to engage in journal clubs, concerts, and movies during the soft summer evenings. And, who could forget, weddings.

Turbo Eco-jargon

Language is fluid and ever-changing, and the creation of new scientific terms can be useful if it makes the language more precise, but it also makes our work less accessible for those unfamiliar with specific literature and to the general public. When we start using overly specialised words as a substitute for more commonplace words, it becomes “turbo eco-jargon”.

An example of eco-jargon that works is the term ‘biodiversity’. It shortens ‘biological diversity’ to one word and still retains its meaning. However, most times we create and use terms that are not intuitive and/or not well defined. This can be especially problematic when terms have a common use, but a very specific scientific use, which may also differ among disciplines. Some examples are: stability, productivity, resilience, traits, and function(ing).

I am probably one of the worst in our lab for using eco-jargon (I was actually scolded by an editor once for my use of ‘turbo eco-jargon’ – his exact words!). But I like creating and using highly specialised words because I think they are fun.

Here are a list of some of my long-term favourite turbo eco-terms; how many do you know? (see comments for definitions)

• cursorial
• vagile / vagility
• phoretic / phoresy
• inquilinism / inquiline
• corticolous
• detrital

Currently I'm working on a manuscript to coin a new eco-term. I'll keep you posted!













Thanks to Biodude for feedback on this post. I look forward to your comments.

rockpool europa


At first glance it is not obvious what this is a picture of. I struggle with my poor photographic skills almost as much as I struggle with biodiversity, and yet these are still the kinds of pictures I take. I won't call it a metaphor.

The fact is this is a picture of a pool of freshwater on a rock face along the Finish coast, and it was teeming with cladocerans - tiny crustaceans that feed on pretty much whatever they can filter from the water column. Rock pools just like this one were made pseudo-famous (at least in the ecological world) decades ago by Ilkka Hanski and other researchers as textbook examples of metapopulations (spatially discrete populations of organisms that are linked by dispersal between the populations). When you pause to think about it, the concept is really cool. The pool is very isolated, may or may not be ephemeral, and yet it is packed with organisms. How did they get there? I occasionally remember that if we cut through all the technical jibber-jabber of spatial ecology, metapopulation ecology, and metacommunity ecology we are left with just such a curious question that could have been posed by anyone and interests everyone.

Many members of the Gonzalez lab, like myself, research nature in a fairly abstract way, tackling theoretical systems or heavily simplified model systems. There are all kinds of advantages to such approaches, but a minor tragedy that results from such minimalist science is a loss of the sheer wonder that you might experience 'out there' were to you stumble upon one of these pools on a morning's walk. The question is rhetorical, but how do we deal with the desire to pin down mechanisms that drive ecological processes, with the sheer wonder (and a skeptic might say incomprehensibility) of reality?

happy canada day all!

The littlest HOBO

“An hour in the field is a week in the lab” was the warning I was given as an M.Sc. student. Which means that Jon and I have enough samples to process for a year.

It has been a highly productive week. I can tell because I’m tired and sore all over. The snow has almost melted, and I escaped before the mosquitoes became too fierce. For the past week we have had a neighbourhood puppy follow us into the bush each day. We call her Georgia – she is very cute. She chases squirrels and takes naps while we measure nitrogen fixation.



P.S. The title of this post is somewhat of an inside joke, as we use HOBO dataloggers to record temperature & relative humidity year-round at the experimental site.  "The littlest Hobo" is also a mainstay of Canadian family television from the 1980s, featuring a wandering dog who helps everyone he happens to meet during his wandering.  Thanks for the company, Georgia.
