First record of the genus Pseudopilolabus Legalov, 2003 (Coleoptera: Attelabidae) in Dominican amber

Creator:: Poinar, George O., Jr., Brown, A. E., and Legalov, A. A.
Abstract:: A new weevil species (urn:lsid:zoobank.org: act:2D5E9E4A-A250-4D0A-AF69-CF4753436686), Pseudopilolabus othnius Poinar, Brown and Legalov, sp. nov. (Coleoptera: Attelabidae), is described from Dominican amber. The new species is close to the extant P. viridanus (Gyllenhal, 1839) and P. splendens (Gyllenhal, 1839) but differs by having a bronzed body, narrower and more convex elytral...

GRACE storage-streamflow hystereses reveal the dynamics of regional watersheds

Creator:: Sproles, E. A., Leibowitz, S. G., Reager, J. T., Wigington, P. J. Jr., Famiglietti, J. S., and Patil, S. D.
Abstract:: We characterize how regional watersheds function as simple, dynamic systems through a series of hysteresis loops. These loops illustrate the temporal relationship between runoff and terrestrial water storage using measurements from NASA's Gravity Recovery and Climate Experiment (GRACE) satellites in three regional-scale watersheds (>150 000 km² ) of the Columbia...

Tapeworm Eggs in a 270 Million-Year-Old Shark Coprolite

Creator:: Dentzien-Dias, Paula C., Poinar, George, Jr., de Figueiredo, Ana Emilia Q., Pacheco, Ana Carolina L., Horn, Bruno L. D., and Schultz, Cesar L.
Abstract:: Remains of parasites in vertebrates are rare from the Mesozoic and Paleozoic. Once most parasites that live in - or pass through - the gastrointestinal tract of vertebrates, fossil feces (coprolites) or even intestinal contents (enterolites) can eventually preserve their remains. Here we announce the discovery of a spiral shark...

Eocene and not Cretaceous origin of spider wasps: Fossil evidence from amber

Creator:: Rodriguez, Juanita, Waichert, Cecilia, von Dohlen, Carol D., Poinar, George, Jr., and Pitts, James P.
Abstract:: Spider wasps had long been proposed to originate in the mid-Cretaceous based on the Burmese amber fossil Bryopompilus interfector Engel and Grimaldi, 2006. We performed a morphological examination of this fossil and determined it does not belong to Pompilidae or any other described hymenopteran family. Instead, we place it in...

Post-fire tree establishment and early cohort development in conifer forests of the western Cascades of Oregon, USA

Creator:: Tepley, Alan J., Swanson, Frederick J., and Spies, Thomas A.
Abstract:: Early‐seral ecosystems make important contributions to regional biodiversity by supporting high abundance and diversity of many plant and animal species that are otherwise rare or absent from closed‐canopy forests. Therefore, the period of post‐fire tree establishment is a key stage in forest stand and ecosystem development that can be viewed...

Nested scales of spatial heterogeneity in juvenile walleye pollock Theragra chalcogramma in the southeastern Bering Sea

Creator:: Benoit-Bird, Kelly J., McIntosh, Neal E., and Heppell, Scott A.
Abstract:: We sought to characterize the distribution of juvenile walleye pollock Theragra chalcogramma in an area of intense predator-prey interactions and to describe habitat features that lead to their observed distributions. The distribution of juvenile walleye pollock around the Pribilof Islands in the southeastern Bering Sea in 2008 and 2009 was...

Mutualistic Co-evolution of Type III Effector Genes in Sinorhizobium fredii and Bradyrhizobium japonicum

Creator:: Kimbrel, Jeffrey A., Thomas, William J., Jiang, Yuan, Creason, Allison L., Thireault, Caitlin A., Sachs, Joel L., and Chang, Jeff H.
Abstract:: Two diametric paradigms have been proposed to model the molecular co-evolution of microbial mutualists and their eukaryotic hosts. In one, mutualist and host exhibit an antagonistic arms race and each partner evolves rapidly to maximize their own fitness from the interaction at potential expense of the other. In the opposing...

A first chronology for the North Greenland Eemian Ice Drilling (NEEM) ice core

Creator:: Rasmussen, S. O., Abbott, P. M., Blunier, T., Bourne, A. J., Brook, Edward J., Buchardt, S. L., Buizert, Christo, Chappellaz, J., Clausen, H. B., Cook, E., Dahl-Jensen, D., Davies, S.

Abstract:: A stratigraphy-based chronology for the North Greenland Eemian Ice Drilling (NEEM) ice core has been derived by transferring the annual layer counted Greenland Ice Core Chronology 2005 (GICC05) and its model extension (GICC05modelext) from the NGRIP core to the NEEM core using 787 match points of mainly volcanic origin identified...

The plant phenology monitoring design for The National Ecological Observatory Network

Abstract:: Phenology is an integrative science that comprises the study of recurring biological activities or events. In an era of rapidly changing climate, the relationship between the timing of those events and environmental cues such as temperature, snowmelt, water availability, or day length are of particular interest. This article provides an...
