Morphological variation, phylogenetic relationships, and geographic distribution of the Baenidae (Testudines), based on new specimens from the Uinta Formation (Uinta Basin), Utah (USA)

abstract: We described newly discovered baenid specimens from the Uintan North American Land Mammal Age (NALMA), in the Uinta Formation, Uinta Basin, Utah. These specimens include a partial skull and several previously undescribed postcranial elements of Baena arenosa, and numerous well-preserved shells of B. arenosa and Chisternon undatum. Baenids from the Uintan NALMA (46.5–40 Ma) are critical in that they provide valuable insight into the morphology and evolution of the diverse and speciose baenid family near the end of its extensive radiation, just prior to the disappearance of this clade from the fossil record. These Uintan specimens greatly increase the known variation in these late-surviving taxa and indicate that several characters thought to define these species should be reassessed. The partial cranium of B. arenosa, including portions of the basicranium, neurocranium, face, and lower jaw, was recently recovered from Uinta B sediments. While its morphology is consistent with known specimens of B. arenosa, we observed several distinct differences: a crescent-shaped condylus occipitalis that is concave dorsally, tuberculum basioccipitale that flare out laterally, and a distinct frontal-nasal suture. The current sample of plastral and carapacial morphology considerably expands the documented variation in the hypodigms of B. arenosa and C. undatum. Novel shell characters observed include sigmoidal extragular-humeral sulci, and small, subtriangular gular scutes. Subadult specimens reveal ontogenetic processes in both taxa, and demonstrate that diagnostic morphological differences between them were present from an early developmental age.The article is published at http://journals.plos.org/plosone/article?id=10.1371/journal.pone.018057

Soft-Shelled Turtles (Trionychidae) from the Cenomanian of Uzbekistan

Localities from the Cenomanian of Uzbekistan are the oldest in Middle Asia and Kazakhstan to preserve two broadly sympatric species of trionychid turtle. Material described here comes from multiple Cenomanian formations from the Itemir locality, and from multiple localities in the Cenomanian Khodzhakul Formation. The first taxon from the locality, "Trionyx" cf. kyrgyzensis, has multiple morphological similarities with the older, Early Cretaceous "Trionyx" kyrgyzensis. In contrast, the second taxon, "Trionyx" dissolutus, has multiple similarities with "Trionyx" kansaiensis, one of two species of trionychid found in younger Late Cretaceous localities. "Trionyx" dissolutus bears some superficial resemblance to other trionychid taxa within the clade Plastomenidae because of its highly ossified plastron with a hyoplastral lappet and an epiplastral notch. However, Plastomenidae is diagnosed primarily through characters that are absent or cannot be observed in the available material of "T." dissolutus, and other shared features are plesiomorphic. In addition, "T" dissolutus shares other synapomorphies with Trionychinae. A heavily ossified plastron may be more homoplastric within Trionychidae than has been previously recognized. Finally, we provide an improved understanding of the subtle similarities and differences between several closely related Cretaceous turtle assemblages of Middle Asia and Kazakhstan.

CIVIC COMMUNITY APPROACHES TO RURAL DEVELOPMENT IN THE SOUTH: ECONOMIC GROWTH WITH PROSPERITY

The free market-based policies of the corporate community model have skewed economic development across the South. For many small, rural communities, the consequences of global capitalism have resulted in declining real wages, high underemployment, and increasing rates of income inequality. Backed by recent scholarship and grassroots movements that suggest both civic engagement and the presence of smaller-scale, locally controlled enerprises can help determine whether communities prosper or decline, this paper explores the links between social structure and rural development in the South. The goal is to expand our understanding of civic community theory as an alternative to the neoclassical economic model of development. Using a local problem-solving framework, we suggest that a departure from the traditional, neoclassical path of development is in order. We conclude that rural policy makers must establish a role for civic community in the rural development process if they wish to protect the welfare of workers and communities, while increasing the prospects of economic growth with prosperity.civic community, economic growth, rural development, social capital, Southern United States, Community/Rural/Urban Development, R11, O21, R58,

Soft-Shelled Turtles (Trionychidae) from the Bissekty formation (Upper Cretaceous: Turonian) of Uzbekistan: Skull-Based Taxa and Probable Skull-Shell Associations

In this paper we describe previously unpublished trionychid turtle material, consisting of skull fragments, from the Late Cretaceous (late Turonian) Bissekty Formation of the Dzharakuduk locality in Uzbekistan. This material is assigned to two taxa: the skull-based Khunnuchelys kizylkumensis Brinkman et al. (1993, Can. J. Earth Sci. 30, 2214-2223) and Trionychini indet. Two specimens which cannot be confidently attributed to these two taxa are considered Trionychidae indet. In addition to these trionychid taxa known from skulls, the Dzharakuduk turtle assemblage includes at least two shell-based taxa, Aspideretoides cf. A. riabinini and "Trionyx" cf. "T." kansaiensis. For this and other Late Cretaceous localities of Middle Asia and Kazakhstan, we suggest the probable skull-shell associations of Khunnuchelys spp. with "Trionyx" kansaiensis-like forms and Trionychini indet. with Aspideretoides-like forms.

This article outlines the benefits of urban agriculture with regard to nutrition, food security, exercise, mental health, and social and physical urban environments. Potential risks are reviewed. Practical recommendations for health professionals to increase the positive benefits of urban agriculture are provided

Epiplastral and geographic variation in Echmatemys, a geoemydid turtle from the Eocene of North America: A multi-tiered analysis of epiplastral shape complexity

Numerous geoemydid turtle fossils from the extinct genus Echmatemys have been recovered from the middle Eocene Uinta Formation, Uinta Basin, Utah over the past several decades. Here, we tested whether co-occurring Uintan species Echmatemys callopyge and E. uintensis can be reliably differentiated based on epiplastral morphology, and whether their geospatial distributions overlapped significantly. The geographic spatial and stratigraphic distributions of Uinta Basin E. callopyge and E. uintensis specimens were compared using ArcGIS and analysis of variance (ANOVA). The analysis revealed overlapping geographic distributions of these two species, and no significant differences in stratigraphic dispersal. This finding of extensive geospatial overlap between the two Uintan Echmatemys species highlights the need for accurate taxonomic identification, such as the gular scale morphology validated here. In addition, we sought to address a methodological question regarding the relative efficacy of data complexity in this context. Using epiplastra from three additional Eocene species of Echmatemys, we employed hierarchical analyses of increasing data complexity, from standard linear dimensions to 2D geometric morphometrics to 3D laser scans, to determine the degree to which data complexity contributes to taxonomic assessments within this genus. Uintan species E. callopyge and E. uintensis were found to differ significantly in epiplastral shape as captured by all three categories of data. These findings verify that these two co-occurring species can be differentiated consistently using the shape of the gular scale, and that the use of geometric morphometrics can improve identification of fragmentary specimens. Among the non-Uintan species, dorsal and ventral 2D landmark data reliably differentiated among species, but the linear dimensions were less useful

Food value chain development in Central New York: CNY bounty

Includes bibliographical references (pages 139-141).In the past 10 years, demand for locally grown food has increased dramatically. Concomitantly, small, commercial farms have declined disproportionately to small and large farms. The decline may be due to the lack of appropriately scaled marketing and distribution resulting from changing markets. This article presents a case study of a component of a food value chain started in 2007, Central New York (CNY) Bounty. CNY Bounty markets and distributes products produced by 119 small, commercial farms and processors to individual households, restaurants, natural food stores, and universities. In the past four years, CNY Bounty has experienced mixed success in terms of its economic viability, which can offer some important lessons for practitioners and contributions for food value chain research

The Multifunctional Attributes of Northeastern Agriculture: A Research Agenda

In the United States' Northeastern region, there is an increasing interest in the public benefits from agriculture. These benefits are frequently referred to as multifunctional attributes. The policy challenge is to find an effective way to reflect these public demands so that multifunctional agriculture can be profitable. There is a significant research agenda that accompanies this challenge. Research topics include assessing and understanding consumer demand for multifunctional attributes, estimating the long-run returns to those production systems which supply these attributes, and designing and evaluating institutional arrangements to supply them.Research Methods/ Statistical Methods,

Agriculture of the Middle Participation in State Branding Campaigns: The Case of Kentucky

In the past decade, statewide agricultural branding campaigns have blossomed. Examining the case of the Kentucky Proud™ (KyP) program, this paper investigates the potential benefit of a state-level marketing strategy for the declining class of midsize farms, referred to as Agriculture of the Middle (AOTM). First, we discuss why AOTM farms are important to maintaining a viable agriculture structure. Second, we introduce the context of state branding and explain how KyP developed as part of the transition from highly tobacco-dependent agriculture. Using recent agricultural census data and a survey of KyP members, we compare the key characteristics between three sets of pairs: (a) U.S. AOTM farmers and Kentucky AOTM farmers, (b) Kentucky AOTM farmers and KyP-member AOTM farmers, and (c) KyP AOTM farmers and other KyP-member farmers. The findings indicate that Kentucky\u27s AOTM farmers are unique compared to U.S. AOTM farmers, and that the KyP program benefits particularly those AOTM farmers transitioning from tobacco-dependent agriculture. We also found that the logo of the state branding campaign helps member farmers differentiate their products, and that the program helps most members gain knowledge and skills for marketing their products. Overall, findings suggest that state branding campaigns designed to incentivize agricultural marketing of local foods have the potential to help farmers of the middle. Further research needs to be done in order to track the long-term impact of different agricultural branding campaigns
