Barking up the Same Tree: a Comparison of Ethnomedicine and Canine Ethnoveterinary Medicine Among the Aguaruna Kevin a Jernigan

Abstract Background: This work focuses on plant-based preparations that the Aguaruna Jivaro of Peru give to hunting dogs. Many plants are considered to improve dogs' sense of smell or stimulate them to hunt better, while others treat common illnesses that prevent dogs from hunting. This work places canine ethnoveterinary medicine within the larger context of Aguaruna ethnomedicine, by testing the following hypotheses: H1 -- Plants that the Aguaruna use to treat dogs will be the same plants that they use to treat people and H2 -- Plants that are used to treat both people and dogs will be used for the same illnesses in both cases. Methods: Structured interviews with nine key informants were carried out in 2007, in Aguaruna communities in the Peruvian department of Amazonas. -

F06108 Nice cedex 02, France * Corresponding author: [email protected] With 5 figures in the text and an electronic supplement Abstract: Green algae (Chlorophyta) are an important group of microalgae whose diversity and ecological importance in marine systems has been little studied. In this review, we first present an overview of Chlorophyta taxonomy and detail the most important groups from the marine environment. Then, using public 18S rRNA Chlorophyta sequences from culture and natural samples retrieved from the annotated Protist Ribosomal Reference (PR²) database, we illustrate the distribution of different green algal lineages in the oceans. The largest group of sequences belongs to the class Mamiellophyceae and in particular to the three genera Micromonas, Bathycoccus and Ostreococcus. These sequences originate mostly from coastal regions. Other groups with a large number of sequences include the Trebouxiophyceae, Chlorophyceae, Chlorodendrophyceae and Pyramimonadales. Some groups, such as the undescribed prasinophytes clades VII and IX, are mostly composed of environmental sequences. The 18S rRNA sequence database we assembled and validated should be useful for the analysis of metabarcode datasets acquired using next generation sequencing. -

PERMIAN BASIN PROVINCE (044) by Mahlon M
PERMIAN BASIN PROVINCE (044) By Mahlon M. Ball INTRODUCTION The Permian Basin is one of the largest structural basins in North America. It encompasses a surface area in excess of 86,000 sq mi and includes all or parts of 52 counties located in West Texas and southeast New Mexico. Structurally, the Permian Basin is bounded on the south by the Marathon-Ouachita Fold Belt, on the west by the Diablo Platform and Pedernal Uplift, on the north by the Matador Arch, and on the east by the Eastern Shelf of the Permian (Midland) Basin and west flank of the Bend Arch. The basin is about 260 mi by 300 mi in area and is separated into eastern and western halves by a north-south trending Central Basin Platform. In cross section, the basin is an asymmetrical feature; the western half contains a thicker and more structurally deformed sequence of sedimentary rock. The Permian Basin has been characterized as a large structural depression formed as a result of downwarp in the Precambrian basement surface located at the southern margin of the North American craton. The basin was filled with Paleozoic and, to a much lesser extent, younger sediments. It acquired its present structural form by Early Permian time. The overall basin is divisible into several distinct structural and tectonic elements. They are the Central Basin Platform and the Ozona Arch, which separate the Delaware and Val Verde Basins on the south and west from the Midland Basin on the north and east, the Northwestern Shelf on the southern extremity of the Pedernal Uplift and Matador Arch, and the Eastern Shelf on the western periphery of the Bend Arch. -

These AstaPs are classified as a novel family of carotenoprotein and are useful for providing valuable astaxanthin in water-soluble form; however, the distribution of AstaP orthologs in other microalgae remains unknown. Here, we exam- ined the distribution of AstaP orthologs in the family Scenedesmaceae with two model microalgae, Chlamydomonas reinhardtii and Chlorella variabilis.

Aqueous orange proteins produced by Scenedesmaceae strains were shown to bind astaxanthin. -

Four ChR families are currently known. Green algal 3–5 and cryptophyte 6 cation-conducting ChRs (CCRs), cryptophyte anion-conducting ChRs (ACRs) 7, and the MerMAID ChRs 8. Here we 25 report the discovery of a new family of phylogenetically distinct ChRs encoded by marine giant viruses and acquired from their unicellular green algal prasinophyte hosts.
