A Hiatus of Sorts

There was a time when I aspired to post weekly, and then bi-weekly, maybe once a month, and now. . . very little.

That’s not to say I haven’t been busy.  I’ve moved a lot of content over to a research website at http://goring.org, with a nice picture of the Wicked Witch of the East (that ought to be properly credited, I’ll fix that. . . ).

I’ve also moved my social advocacy stuff to either Twitter, or institutionally within EarthCube, where I’m now a member of the Leadership Council & head of the Engagement Committee.

It all comes down to time.  I find that it takes me a lot of time to write a blog post, and my time seems to be stretched thinner than it was before.  Something needed to give, and, in the end it was either my sanity & work-life balance, or this blog (and a couple other things).

I stand by all my old posts, I think they’re all equally fantastic, but please check out my website for more current information on what I’m up to.  Thanks for stopping by.

Who is a Scientist – Reflections on #AAG2016

This is the first time I’ve really been to the American Association of Geographers meeting. Last year it was held in Chicago, which is really close to Madison, and I was invited to speak at a session called “The View from the Anthropocene” organized by two great Geographers from the University of Connecticut, Kate Johnson and Megan Hill, but I had the kids & really only spent the morning there.  I’m pretty sure there was another reason as well, but I can’t remember what it was.

It was great to see Kate & Megan again this year, both of them are doing really cool stuff (check out their web pages), and it was really great to see that the momentum behind the original idea was enough to re-tool the session into the Symposium on Physical Geography at this year’s AAG meeting in San Francisco, with Anne Chin of UC-Denver on the organizing committee, and a host of fantastic speakers.

My own presentation in the session focused on the Anthropocene, and its role as both a boundary (whether you want to define it as an Epoch sensu stricto or as a philosophical concept – I think that Stanley Finney & Lucy Edward’s article in GSA Today nicely lays out the arguments) and a lens.  The second part of that equation (the lens) is a more diffuse point, but my argument is that the major changes we see in the earth system can impact our ability to build models of the past using modern analogues, whether those be climatic, or biological.  I show this using pollen and vegetation records from the Midwest, and make the connection to future projections with the example laid out in Matthes et al. (2015), where we show that the pre-industrial climate niche of plant functional types used in GCMs as part of the CMIP5 intercomparison are not better than random when compared to actual “pre-settlement” vegetation in the northeastern United States.

But I really want to talk about a single slide in my talk.  In the early part of my talk I use this slide:


This is Margaret Davis, one of the most important paleoecologists in North America, past-president of the ESA [PDF], and, importantly, a scientists who thought deeply about our past, our present and our future.  There’s no doubt she should be on the slide.  She is a critical piece of our cultural heritage as scientists, an because of her research, is uniquely well suited to show up in a slide focusing on the Anthropocene.

But it’s political too.  I put Margaret Davis up there because she’s an important scientist, but I also chose her because she’s an important female scientist. People specifically commented on the fact that I chose a female scientist, because it’s political.  It shouldn’t be.  There should be no need for me to pick someone because of their gender, and there should be no reason to comment on the fact that she was a female scientist.  It should just “be”.

Personal actions should be the manifestation of one’s political beliefs, but so much of our day to day life passes by without contemplation.  Susanne Moser, later in my session, talked about the psychological change necessary to bring society  around to the task of reducing CO2, of turning around the Anthropocene, or surviving it, and I think that the un-examined life is a critical part of the problem.  If we fail to take account of how our choices affect others, or affect society then we are going to confront an ugly future.

Everything is a choice, and the choices we make should reflect the world we want for ourselves and for the next generations. If our choices go un-examined then we wind up with the status quo.  We wind up with unbalanced panels, continued declines in under-represented minority participation in the physical sciences, and an erosion of our public institutions.

This post is maybe self-serving, but it shouldn’t have to be.  We shouldn’t have to look to people like DN Lee, the authors of Tenure She Wrote, Chanda Prescod-WeinsteinTerry McGlynn, Margaret Kosmala, Oliver Keyes, Jacquelyn Gill and so many others who advocate for change within the academic system, often penalizing themselves in the process.  We should be able to look to ourselves.

Okay, enough soap-boxing. Change yourselves.

See you at #AGU2015

I’m heading to AGU early this year, part of the Neotoma Annual Meeting at Berkeley.  We’ve recently been awarded an NSF EarthCube Integrated Activities award to harmonize Neotoma and the Paleobiology Database (and other allied paleobiological archives), but we’ve also made some big gains in working with allied Plio-Pleistocene databases and researchers across the globe in adding to Neotoma’s already considerable data holdings.

I’m looking forward to the upcoming Neotoma meeting. One very exciting development is our partnership with the University of Wisconsin’s Library System.  We’ve been working toward providing data contributors with persistent Digital Object Identifiers (DOIs) for their contributions.  Our work with the UW Library System has seen a new contract established between the UW Libraries and DataCite, which gives us access not only to DOI minting, but also new connections to a set of established metadata standards and a robust API for minting DOIs, editing metadata and searching for contributions.

My own poster [GC11E-1065] goes up on Monday Morning (so get registered early!) as part of the Dating the Anthropocene session.  There was a great paper in Eos in the last issue (What is the Anthropocene? by L. Edwards) that lays out some options for ways in which geoscientists might treat the Anthropocene.  My work in the Upper Midwestern United States leads me to believe that there is a clear and persistent signal of human agency on the landscape, but it’s time transgressive, and it varies.  It was nice to see Edwards point to some of the pioneering work by the great Canadian palynologist Jock McAndrews, but the signal of EuroAmerican settlement is so broad it clearly represents a state change (see our pre-print here, now in review), as opposed to the signal of earlier human land use, nicely reviewed in Munoz et al (2014).  If you want to talk about it, come find me on Monday!

Jack Williams will be presenting some of the work we’ve been doing with Neotoma with his poster on Tuesday afternoon in the poster session [IN23B-1731] for Facilitating Open Science and Data through Scientist Engagement and Evolving Technology.


Alan Ashworth is also talking about Neotoma in another presentation on Tuesday from 9:15 – 9:30 in the Agile Curation, Data Access and Infrastructure, and Data Layers session.  This, incidentally, is a session that I am convening, along with Denise Hills of the Alabama Geological Survey and Marjorie Chan of the University of Utah, the two chairs of the EarthCube Engagement Team.  I am also convening the Facilitating Open Science through Engagement and Evolving Technology poster session on Tuesday afternoon.  Some great opportunities to find out about both EarthCube sponsored open data initiatives & the broad range of data and science platforms that are being developed.

So, once again, a very busy AGU for me, and I haven’t even mentioned Kevin Burke’s great poster on Monday morning.  Having finished his M.Sc Kevin is on to more great work modeling the influence of changing wind fields on our ability to reconstruct past vegetation from pollen data.

Hope to see you at AGU, I’ll be there from Friday to Wednesday, so if you’d like to get in touch, let me know!

The interdisciplinary study of organic walled microfossils: A ramble.

It’s no secret to members of the Canadian Association of Palynologists (join now!) that the study of organic-walled microfossils is the most interesting branch of science, but it may come as a surprise to some of our colleagues. The thing is, our colleagues all have their own opinions. If they’re in biology departments they probably like bears; geology, they probably like different kinds of gravel; geography, obviously they like the names of rivers and knowing where towns and cities are.  The reality of being a palynologist is that you’re often working in a department that specializes in something that isn’t palynology. From time to time this can be a curse, but it’s also a very exciting opportunity.

This year I had the pleasure of attending both the Ecological Society of America meeting and the Geological Society Meeting, both of which were held in Baltimore, Maryland (39.2833° N, 76.6167°W for the Geographers).  At both meetings I co-chaired a session titled “Paleoecological patterns, ecological processes, modeled scenarios: crossing temporal scales to understand an uncertain future”. The sessions highlighted the applications of paleoecology to understanding the processes of ecological and geophysical change across decadal to millennial time scales.

It really is a testament to palynologists (and paleoecologists more broadly) that neither session felt out of place in either ESA or GSA. The nature of the problems we address through our research rely on the integration of ecological knowledge and geophysical process.  Both sessions had impressive contributions from early-career researchers and established researchers, and both sessions pointed to new and unexplored avenues of research. Both sessions also showcased a bit of the flavor of the meetings themselves.  The ESA talks focused more on ecological processes, the accumulation of carbon in ecosystems, forest cover change and regional dynamics, and change within ecological systems.  At the GSA meeting there was a much heavier imprint of climate and deeper time scales.

In recent years paleoecology has become more visible to ecologists as they have begun to tackle the complex problems of predicting community change under various climate change scenarios.  At the same time, questions of carbon dynamics, vegetation-atmosphere feedbacks, and other large scale questions of relevance to geoscientists have increasingly drawn from the knowledge of paleoecologists and palynologists.  Of course, there is a long tradition of paleoecologists contributing significantly to interdisciplinary sciences. Palynologists have been using their unique view of the earth system over long time scales to help frame our understanding of the Earth’s past as far back as von Post (see Conway’s overview of von Post’s work in the New Phytologist).

Palynology is great precisely because the people studying it continue to pursue innovative and exciting research that borrows strongly from our history as a deeply interdisciplinary discipline.  It is this interdisciplinary history that allows us to present our work to Foresters, Ecologists, Geologists, Climatologists, or Oceanographers. We have to be a little bit of all of these in order to make sense of the microscopic organic-walled microfossils that we see dancing under the microscope. [note: if they really are dancing you should cut down on the silicone oil]

People, climate, fire. The Future meets the Past, and decides it wants to do its own thing.

I’ve been very lucky to work with great co-authors over the past few years, and this year is no exception. Along with a raft of papers we are about to submit I just got notified that a paper we submitted a few months ago is now online in the Annals of the Association of American Geographers (journal title chosen in the pre-Twitter age, obv.).

This paper, with Megan Walsh, Jenn Marlon, Dan Gavin and Kendrick Brown (and also me!) is a great look at fire records from the Pacific Northwest (PNW) over the last 5000 years. This time period is particularly critical to understanding human-climate-fire relationships. Human populations over the last 5000 years were increasing in the region, and climate was shifting, gradually cooling and becoming more moist following the early Holocene xerothermic period.

The challenge is that the PNW is an incredibly heterogeneous region. You can hike nine kilometers and shift from dry valley bottom to an alpine peak. Most of the climatic gradients are more homogeneous on the NS axis than they are on the EW axis.  The more critical problem is that, in a more general sense, human activity, on a landscape scale, is very difficult to detect or attribute prior to widespread EuroAmerican colonization (see Sam Munoz‘s excellent paper here).

Our paper comes out at a particularly important time.  We’ve seen an incredible fire season in the Pacific Northwest this year, driven in part by very dry conditions, both during the summer, but, more importantly by low snow packs in the winter.  Knowing that past fire regimes in the region increased, even as temperatures cooled through the late Holocene, has serious implications for the future.  Biomass stocks in the PNW remain high (even following widespread logging), and the open fire-dominated forests that were adapted to warmer drier conditions of the early Holocene (mostly Douglas fir-dominated) are no longer established in the region.

We may be burning ourselves to a new ecological baseline.

Amy Hessl, who was a co-convener on our fantastic ESA session this year (link), has a nice paper in Ecological Applications from 2004 linking the Pacific Decadal Oscillation to fire activity in the PNW interior (here) based on a set of fire scar data, so changing the intensity and frequency of these climatic systems is certainly going to shift our frequency and intensity.  Wimberly and Liu (2014) support the idea that management focused on reducing biomass on the landscape (prescribed burning and thinning) will help counter increasing fire severity and frequency, suggesting that management may be the key in transitioning to a warmer, drier future, and the key to understanding what these future forests might look like.

Fire in the early Holocene resulted in forests on the north shore of Vancouver with much higher proportions of Douglas fir pollen than are found in many modern day sites (see Marion Lake on the Neotoma Explorer – here, and check out the “Diagram” tab).  Douglas fir is not a heavy pollen producer, and yet it reached almost 20% of the pollen sum, along with higher proportions of Alder and Bracken fern, a fire-adapted fern.  Currently these taxa are found in low proportions throughout the PNW, except in regions with very low rainfall, and historically low fire return intervals, and proportions of Douglas fir over 20% are almost entirely restricted to southern Vancouver Island in British Columbia, although there may be higher proportions in the US.

Are we heading to a new, old baseline?

It’s unlikely that we’ll see fire return intervals as high as we’ve seen in the past.  Active fire management will certainly keep fire activity lower than in the Holocene record because we put so much effort into countering large-scale fire.  The interesting thing to me is the idea that we’ll be managing these landscapes for fire, so we’ll have aspects of forest structure that map onto historical forests well: more open canopies, lower biomass, fire tolerant species, but, because of political volatility of prescribed burning, we are likely to see some fire tolerant species absent from the landscape, particularly understory species that we are unlikely to manage.  This might lead to novel species assemblages, with fire tolerant canopy species, and less tolerant understory species.  The result of a “fire adapted” landscape that has arisen as the result of active management in the absence of fire.  Planting, thinning, and continued management, without the presence of fire.

This maps well to what we’ve seen in the Georgia Basin, the encroachment of Scotch Broom into what has historically been Garry Oak Savanna.  We have open canopies, a shrub layer of highly flammable, introduced and invasive species, but still the structural attributes of a savanna landscape, minus grasses, so, uh, well, not exactly savanna.  But that’s fine, because I said there was no real analogue, so QED.  This post is too long anyway 🙂

ESA 2015 – On the way to a new century!

I’m involved in a Plenary Workshop this year, organized by some great folks at UNC-Chapel Hill.  I’m privileged to have been asked by these students, al of whom are currently Ph.D candidates.  They’ve taken a great idea and turned it into something that will be an excellent Plenary Session, with some (hopefully) long lasting impact.  Given the subject (the future of interdisciplinary ecology) it’s also perfectly well suited to the centennial ESA meeting.  They’ve just posted this to ECOLOG so I wanted to share it here, since many of my readers are likely involved in interdisciplinary research themselves.

Dear members and friends of the Ecological Society of America (ESA): This survey is relevant to all ecologists, especially those engaged in interdisciplinary research. In celebration of the Centennial of ESA, a team of doctoral students at UNC Chapel Hill are conducting a study to assess the state of interdisciplinary research and scholarship inside and outside of the academy (IRB #15-0821). The results of this study will be shared at an upcoming workshop convened as part of the 100th Meeting of the Ecological Society of America. Results are intended to help workshop organizers identify the challenges and rewards that interdisciplinary ecologists encounter. Click here for more information about this ESA Plenary Workshop and how you can still register (Aug 8th @ 306 Baltimore Convention Center). We welcome participation from ecological researchers at all career levels.

This online survey will take 15 minutes to complete. The survey link will remain active until July 15, 2015. Your participation is completely voluntary and confidential. Keep in mind that no compensation is provided. Your confidential feedback will be used for a peer-reviewed publication and shared widely with the global community of ecologists. Research methods are in full compliance with IRB policies regarding confidentiality and research ethics of the University of North Carolina at Chapel Hill. Please contact Principal Investigator Clare Fieseler for further questions or comments about the survey (link to Ecolog post with contact information)

The long tail of under-representation

I am by no means an expert on the subject of under-representation in the sciences.  There are some excellent academic bloggers who have done some great work in discussing issues around race and gender in academia (including DNLee, the tweeters at and using #BlackandSTEM – EDIT: this is an amazing post by Dr. Chanda Prescod-Weinstein over at medium.com).  This post is intended to highlight what I’ve observed and experienced over the past year or so, with a specific observation surrounding the EarthCube Early Career Travel Grant.

The issue of diversity is tricky in academia, because diversity means different things to different people.  In a phone interview I once asked what sort of supports the department had to increase diversity and was told that they had a number of women on faculty. Period.  Um . . . I guess that’s one aspect of diversity, but if that’s the end of it, then there are some problems that need to be addressed.

The National Sciences Foundation has specifically addressed diversity in the Geosciences with a number of initiatives, for example the “Opportunities for Enhancing Diversity in the Geosciences (OEDG) Program” which (as far as I know) lapsed in 2012, and the subsequent report “Strategic Framework for Education and Diversity, Facilities, International Activities, and Data and Informatics in the Geosciences” (PDF).  Among disciplines supported through the NSF the geosciences is one of the least diverse, and this problem needs to be addressed.

As part of the EarthCube Engagement Team I drafted the EarthCube Early Researcher Travel Grant along with my Team colleagues, who are all fantastic and engaging people and great scientists (you should join our team, check out the link).  In providing a larger pool of money for EC researchers from under-represented backgrounds we are recognizing that the causes of underrepresentation are not always overt, but are often structural, related to a lack of funding for travel (in this case), and, correlated to that, a lack of visibility for the research products that these researchers might be developing.

This brings up the secondary issue: Who is part of an under-represented group in the geosciences?

It should be clear that the NSF Geo does value diversity, and has explicitly laid out the groups it considers underrepresented:

“women, minorities (African-Americans, Hispanics, Native Americans, Alaska Natives, Native Hawaiians and other Pacific Islanders), and persons with disabilities”

But this is not an exhaustive list.  If you’ve read Tenure She Wrote with any regularity you’ll have come across some of the posts by the author dualitea (see here, and here for some examples).  For me many of these posts have been eye-opening, and indicate the much broader set of individuals that are not well represented in the sciences, let alone the geosciences.  Along with trans academics we can include the broader LGBT community, potentially invisible, but also underrepresented.  In addition acclimatrix and sarcozona have posted about economic background and academia (respectively here and here).  There are obviously many groups of under-represented scholars that lie outside the defined bounds.  Even thinking about Terry McGlynn’s work on Small Pond Science (e.g., here and here), we could potentially include students from smaller universities.  Limited by lack of funding and opportunity, and in need of greater, and more flexible support from non-traditional sources (such as the EarthCube funding).

So, I bring this all up in an effort to answer a question we received about the Early Career Travel Grants: “What is an under-represented group”?

In our proposal we specifically phrased this portion of the text to read:

Individuals that self-identify as part of an underrepresented group within the geosciences may apply for a $1000 travel grant.

In response to the question as posed we have added further text to the grant:

Applicants are asked to self-report if they constitute as an underrepresented minority. This is to allow for a greater breadth in determining what constitutes diversity within the geosciences, but also to allow applicants to empower themselves by clarifying how this proposal and funding will help further the goals of a broad and diverse geosciences discipline.

I think this does two things.  It leaves self-definition open, and provides an opportunity for people to use their own voice to define the challenges they face in a non-judgemental way.  We’ve pointed to resources individuals can use to help define what it means to be under-represented in the geosciences, and, hopefully, provided a way to develop a voice around their place in academia and the geosciences.

Does this approach open the possibility that the grant will be abused by people who try to justify ‘under-representation’ that doesn’t exist: “White left-handed males” (my particular group)?  Maybe, but I’d rather see people get the money to break down barriers, than generate another barrier to access for people who really need it.

This is a long post, but I thought that it might be interesting for people, and I’m genuinely curious how people feel about this, so please chime in in the comments.

If you know anyone who might be interested in this grant, please forward the link on to them, and if you know of any networks we can use to advertise this and future funding opportunities more widely please let us know!
