Super cool meta-analysis of fluvial reconstructions focused on regional watersheds of the eastern United States, by UA PhD student Ray Lombardi, published in Holocene.
In this paper we use baldcypress to develop a false ring record extending from 1881 to 2014. All 20 of the false-ring events recorded during the instrumental period occurred during years in which greatly increased streamflow occurred late in the growing season. Many of these wet events appear to be the result of rainfall resulting from landfalling tropical cyclones.
In this recent paper we look at inter-annual tree-ring anatomical variability and vessel width in overcup oak (Quercus lyrata) and river flooding at a bottomland hardwood forest site near the confluence of the White and Mississippi Rivers.
Met up with fellow dendro folks Grant Harley from Southern Miss and Clay Tucker from LSU (and others) to core bald cypress on the lower Pascagoula River to study streamflow. We also found a lot of nice overcup oak.
Went down to Bruce, Florida with Civil Eng. colleague G. Tootle as well as a great group of Environmental Science and CE students to core bald cypress trees to support a reconstruction of Choctawhatchee River streamflow. We were updating an earlier collection by D. Stahle as well as collecting some fantastic subfossil samples some of which
Made a quick trip up to eastern Illinois in December to sample bottomland oak at Sielbeck Forest and Beall Woods, both of which have some very nice old growth oak. Sielbeck is just north of Metropolis IL, in the former channel of the Ohio River (8K years ago) and Beall Woods is adjacent to the
Had a great time last week with Matt Meko collecting tree-ring samples in Illinois from sites sampled by D. Duvick in 1980. We were joined at Ferne Clyffe St. Park by Justin Maxwell and his crew and and Kankakee St. Park and Starved Rock St. Park by Emma Bialecki (@emmabialecki). We saw some great old
In addition to sampling live trees, we were able to find a few dead standing snags and downed logs to sample. Hopefully these will help us get farther back in time than the living trees. For more pics see https://plus.google.com/+MatthewTherrell/posts/1yHufupf55b
Had a “great” trip to the WRNWR to sample old overcup oak (Quercus lyrata) along Scrubgrass Bayou, and by great I mean we didn’t perish though I thought we might at times given the lightning and terrible heat, insects, and noxious plants. Matt Meko is shown coring a nice mature overcup. For more pics see https://plus.google.com/+MatthewTherrell/posts/1yHufupf55b
If you are into old plantation houses Lakeport Plantation in eastern Arkansas is one of the finest restored examples in that state. A few years ago Dave Stahle and I used tree-rings to date the construction of the main house. It was built almost entirely of bald cypress, and nearly every log was cut in
The mfecane is thought to be a massive upheaval and devastation of Nguni tribal chiefdoms in the second decade of the 19th century in what is now KwaZulu-Natal and the Eastern Cape of South Africa. We show that pervasive cycles of drought and cold periods in southern Africa are significantly amplified and extended by volcanic
The objective of this study was to determine if a large-scale wind disturbance facilitated the invasion of forest interiors by non-native invasive plant species in the northern portion of LaRue Pine Hills – Otter Pond Research Natural Area in the Shawnee National Forest of southern Illinois. doi: http://dx.doi.org/10.3375/043.033.0309
