Literature on riparian ecosystems

Wednesday, November 30th, 2011

December 2011 article (early view): “Threats to Riparian Ecosystems in Western North America: An Analysis of Existing Literature,” by Boris Poff, Karen A. Koestner, Daniel G. Neary, and Victoria Henderson

This literature review does more than simply list publications. Judging from topics of papers, it looks at how threats to riparian ecosystems have been perceived in the literature.

A total of 453 journal articles, reports, books, and book chapters addressing threats to riparian ecosystems in western North America were analyzed to identify, quantify, and qualify the major threats to these ecosystems as represented in the existing literature. Publications were identified either as research, policy, literature review, historical comparison, or management papers. While the types of threats vary on spatial and temporal scales, some persist through decades in western North America. This analysis shows that grazing has been perceived as a dominant threat since the 1980s, but has been diminishing in the past decade, while invasive species, dams and, in recent years, climate change are increasingly represented in the literature as threats to riparian ecosystems in western North America.

A Small Interruption

Wednesday, November 30th, 2011

If you’ve wondered why this blog has been a little quieter than usual, this photo explains why. I have been out in Oak Park, Illinois with James, our first grandchild. James was born November 7th, and is a delight. Just had to brag!

I can work on the road, but there are a lot of distractions. I’m back home now. A whole bunch of stuff has accumulated in my queue, which I will deal with starting tomorrow.

Talks/Posters -> Papers

Thursday, November 17th, 2011

So far, I’ve sent out over 60 emails encouraging presenters of talks or posters to consider developing them into JAWRA papers. I personally reviewed all the posters and sat in on many of the talks. For others, since I couldn’t be everywhere at once, I conferred with an Associate Editor or others who attended. Only as a last resort did I simply invite a promising title. I’m even looking into a Featured Collection on one topic. The Associate Editors and I will be contacting additional potential authors in the future.

Don’t feel bad if we didn’t contact you! Not all interesting talks lend themselves to JAWRA papers. Many are very critical for practitioners but are not candidates for a research journal. Similarly, panel discussions often give up-to-date insights into agency procedures or regulations but do not provide materials for JAWRA.

If you think we inadvertently passed over inviting a potential paper, please still feel free to submit it via our ScholarOne Manuscripts system.

Stationarity of streamflow records

Monday, November 14th, 2011

December 2011 article (early view):Stationarity of Streamflow Records and Their Influence on Bankfull Regional Curves,” by Jessica Haucke and Katherine A. Clancy.

This study is a good reminder that nonstationarity is a fact, whether the cause is climate change or simply anthropological changes in the watershed itself.

The authors examined the assumption of stationarity in determining bankfull regional curves in the Driftless Area of southwestern Wisconsin where agricultural soil retention practices have changed, and precipitation has increased since the 1970s. Their research suggests that land conservation practices may have a larger impact on gaging station stationarity than annual precipitation changes do.

With changes in land use or climate, the gage’s period of record should be analyzed for significant differences in Q1.5 values. Often rivers with long periods of record (>30 years) are preferable for regional curves, but early peak flow data may not reflect the current hydrologic regime. In some cases, it may be better to truncate datasets so as to reduce the influence of older data.

Report from Albuquerque

Friday, November 11th, 2011

AWRA held a great annual conference. There were lots of fantastic talks and posters. The Associate Editors and I will be contacting many of the authors, to scout out potential JAWRA papers.

It’s always hard to get together in person, but the Associate Editors’ Luncheon was well attended. Brian Caruso came all the way from New Zealand. Steve Preston, Joe Delfino, and Venki Uddameri also made it, along with AWRA’s current and future Presidents. An airline delay caused Linda Prokopy to miss the luncheon, but we met her later; she gave some great presentations.

Albuquerque

Tuesday, November 1st, 2011

Just so you know, I will be at the AWRA 2011 Annual Water Resources Conference in Albuquerque, November 7-10. If you haven’t already made your reservations, there’s still time. It promises to be a great meeting.

I’ll be the one walking around with the “JAWRA Editor” ribbon.
