Field and microstructural observations from the Proterozoic Grizzly Creek Shear Zone suggest that crustal-scale fabric anisotropy exerted a significant control on earthquake rupture propagation during deformation at mid-crustal depths. The shear zone developed in amphibolite-facies supracrustal gneisses and granitoids, and consists of a 0.4-0.7 km-wide zone of high-strain rocks with foliation transposed to 256°/51°NW and top-to-the-south kinematics. The shear zone is overprinted by hundreds of veins of pseudotachylyte, mylonitic pseudotachylyte and ultramylonite. Field observations and whole-rock geochemical data suggest that pseudotachylyte fault veins formed as a result of first-generation rupture through intact rock. Pseudotachylytes are preferentially localized in as many as nine decametre-scale rupture zones dispersed across the width of the shear zone, concordant to foliation. We present a conceptual model for the asymmetric development of anisotropic fabric in a thrust-related fault zone in crystalline metamorphic rocks. Progressive tectonic exhumation of hanging wall rocks during thrusting results in the development of a crustal-scale anisotropic fabric that provides a preferentially weakened zone that could accommodate the propagation of earthquake ruptures from the seismogenic zone into the middle crust. © The Geological Society of London 2011.

A new species of a non-marine microconchid (Tentaculita) tubeworm, Microconchus hintonensis, from the Lower Carboniferous (Upper Mississippian, Chesterian) of West Virginia, USA, is described. Non-marine microconchids occur abundantly in the deposits of the Bluefield, lower Hinton, Princeton and Bluestone Formations of the Mauch Chunk Group, where they are either associated with land plant remains and bivalve shells, or are preserved loose in the host sediment. The specimens attached to plant remains and bivalve shells, are poorly preserved, but those occurring loose in the deposits are well-preserved in three dimensions. The interpretation presented here, is that the loose specimens of Microconchus hintonensis sp. nov. also originally encrusted plants (land plants, algae) and bivalve shells, but became detached after substrate degradation and dissolution. The association of land plant remains, charophyte gyrogonites, bivalves, ostracodes, conchostracans, and fish teeth and scales, and the concomitant lack of strictly marine fossils indicate that the microconchid-bearing deposits of the lower Hinton, Princeton and Bluestone Formations were deposited in fresh-water environments. Microconchus hintonensis sp. nov. is regarded as a highly fecund, opportunistic species that in large numbers colonized every available substrate in its habitat. Its abundance in the deposits investigated indicates that the species was welladapted to the environments it occupied, even during episodes of higher sedimentation rates and/or competition with other soft-bodied encrusters. During such episodes, microconchids were able to grow vertically by uncoiling and elevating their tubes, in order to escape potential burial and/or overgrowth by other encrusters. Source

Identification of positional behavior adaptation in the pelvis of primates is complicated by possible confounding effects of body size and phylogeny. Previous work on primate pelvic allometry has focused primarily on sexual dimorphism and its relationship to obstetric constraints in species with large fetal size relative to maternal size. This study investigates patterns of pelvic scaling with a specific aim to understand how pelvic scaling relates to locomotor function. Patterns of scaling of nine pelvic dimensions were examined in a broad comparative sample of 40 species of primates, covering both haplorhines and strepsirrhines, while accounting for phylogenetic nonindependence. Phylogenetic reduced major axis regressions on pelvic scaling patterns suggest that primate-wide patterns are reflected in haplorhine- and strepsirrhine-specific analyses. Many measures scale isometrically with pelvis size, but notably, features of the ilium tend to scale allometrically. As predicted, ilium width and lower ilium cross-sectional area scale with positive allometry, while lower iliac height scales with negative allometry. Further regression analyses by locomotor group suggest that these ilium measures, as well as pubic symphysis and ischium lengths, differ in their scaling patterns according to locomotor mode. These results suggest that scaling differences within primates, when present, are related to functional differences in locomotor behavior and mechanics. This study supports recent work that identifies adaptations to locomotor loading in the ilium and highlights the need for a better understanding of the relationship between pelvic structural mechanics and the mechanical requirements of primate locomotion.

This project will examine how an authentic, multi-year research experience embedded within a 5-course sequence impacts the progressive professional preparation of undergraduate geoscience students. Multiple evidence-based studies published in the STEM education literature continue to affirm that participation in undergraduate research results in numerous cognitive, personal, and professional gains among STEM students. Recently emerging results suggest that longer-term experiences increase these benefits and are needed for more sophisticated skills to mature. It is challenging, however, to offer long-term experiences to large numbers of students via commonly used approaches. For example, curriculum-embedded research is typically short term, and longer-term independent study projects are often too resource intensive to reach beyond a select number of students. The investigators will test a more scalable model that provides a long-term unified experience while simultaneously reaching a broader cross section of students. The project team will immerse all geoscience majors in a thematic multi-year research project embedded within the core curriculum, including a summer geology field course. The investigators will examine the development of (1) research skills such as data acquisition and analysis, (2) personal gains such as student confidence and the ability to think like a scientist, and (3) communication skills to both scientists and the general public. The latter addresses both oral and written communication as well as the emerging use of social media for science communication. By carefully following student progress over 2 years, the team expects to capture when and how these skills develop and mature and what aspects of the experience are key to this development.
The authentic research experience focuses on (1) the rupture dynamics of earthquakes in and the longer-term rheological evolution of an exhumed Proterozoic age shear zone in the Colorado Rockies, and (2) the petrology of the rocks which host the shear zone. The field area is studied during an existing summer field course. Students will begin a project in their first sophomore-level geoscience course and continue with the same research project for 5 consecutive courses culminating at the summer field course. The student projects will advance the understanding of physical and chemical processes associated with earthquake rupture at the multi-kilometer scale near the base of the seismogenic zone where large earthquakes nucleate. This project will be based at a primarily undergraduate institution with an unusually large percentage of first-generation and low-income students in rural Appalachia. This will allow the study of outcomes achieved by an underserved population of students and compare them to national studies with different student demographics. Since the curriculum incorporates the development of communication skills, additional impacts include preparing the next generation of scientists to effectively convey science to the general public through face-to-face outreach and the use of social media.

The interest for organic crop production is in the increase due to a strong demand for organic food from consumers and an attractive income potential for farmers. Weeds pose one of the major problems in crop production and are responsible for significant crop yield reduction. The problem of controlling weeds without synthetic herbicides under the rules of organic agriculture is challenging. The increase in the number of herbicide-resistant. weeds, the increase in herbicide cost, and the movement of herbicides into surface and ground water have sparked public awareness and restrictions on herbicide use. For these reasons, weed scientists are considering alternative and integrated weed management practices to reduce herbicide inputs and impacts. The use of propane for flame weeding can be adopted as one of the alternatives to chemical weed control, as it eliminates concerns over direct residual effects on soil, water, and food quality and can lessen the reliance on herbicides, hand weeding, and/or mechanical cultivation. Flame weeding is an acceptable weed control option in both organic and conventional production systems. A greater knowledge on the development of dose-response curves for determining the appropriate propane dose for effective weed control in major agronomic crops is needed to improve flame-weeding strategies. The dose-response curves for weeds and crops are important so that the lowest effective dose of propane can be applied for weed control in agronomic crops, which saves energy and reduces production costs. Depending on the desired level of weed control or tolerable crop injury level, a propane dose could be selected to either control the weed, or reduce its competitive ability against the crop. In this chapter, we will provide an overview of the findings from the flaming research that has been conducted for the last six years at the University of Nebraska, USA, or reported in pertinent newest literature. This chapter will improve our existing knowledge about flame weeding and will present better general guidelines for both organic and conventional crop producers interested in flaming techniques for weed control. © 2013 Elsevier Inc.
