Reed Boats and Experimental Archaeology on Lake Titicaca
Paul Harmon tests the capabilities of the local totora reed boats. In the past few decades, hollow-hulled wooden boats of European design have largely replaced totora reed boats among the Aymara and Uru-Chipaya peoples of the region. Reed Boats and Experimental Archaeology on lake titicaca by alexei vranich, s much as archaeologists grumble about the scientific merit of Thor Heyerdahl’s paul harmon, and Kon Tiki journey from Peru to Polynesia, one thing is certain: he started a trend. On chris knutson the positive side, archaeologists began experimenting with a variety of ancient n o m technologies as a means to understand r a H l the past. On the negative side, a generation of adventurers u a P d A n decided that the best way to prove their ideas was to build a a h c i raft and set it adrift. Since the famous Kon Tiki, at least 40 sim- n a r V i ilar expeditions have generated adventure by inventing more e x e l and more improbable ways to get from one place to another. A 20 volume 47, number 2 expedition Boats made of everything from popsicle sticks to wine corks have been spotted all over the world, including a reed boat seen recently cruising down the Amazon River en route to Africa using powerful outboard motors! As we spent three months assembling nearly two million totora reeds into a giant bundle 13,000 feet above sea level on the edge of Lake Titicaca in South America, we wondered in which group we belonged, the archaeologists or the adventurers? TIWANAKU AND ITS MONOLITHS Around AD 500, one of the small villages along the shores of Lake Titicaca grew into the largest city that had ever existed in the Andes. -

This study investigated the levels of Cd, Cu, Mn, Ni, Pb, and Zn in water and whole fish. We sampled 40 juvenile silversides Odontesthes regia and 41 juvenile puye Galaxias maculatus from the Valdivia River estuary, adjacent to the urban area in southern South America (Chile). Samples were analyzed using a flame atomic absorption spectrophotometer. In water samples, metals except Zn were mostly below the detection limits and all metals were below the maximum levels established by local guidelines in this estuary. In whole fish samples, concentrations of Cu, Zn, Pb, Mn, and Cd were significantly higher in puyes than in silversides. Additionally, Zn, Pb, and Mn were correlated to body length and weight in puyes, whereas Cd was correlated to body length in silversides. The mean concentration of heavy metals in silverside and puyes were higher than those reported in the literature. -

The phylogeny is calibrated with six carefully chosen fossil taxa to pro- vide an explicit timeframe for the diversification of this group. Our results support the subdivision of Keywords: Atheriniformes into two suborders (Atherinopsoidei and Atherinoidei), the nesting of Notocheirinae Silverside fishes within Atherinopsidae, and the monophyly of tribe Menidiini, among others. We propose taxonomic Marine to freshwater transitions Marine dispersal changes for Atherinopsoidei, but a few weakly supported nodes in our phylogeny suggests that further Molecular markers study is necessary to support a revised taxonomy of Atherinoidei. -

Early Settlement Ofrapa Nui (Easter Island)
Early Settlement ofRapa Nui (Easter Island) HELENE MARTINSSON-WALLIN AND SUSAN J. CROCKFORD RAPA NUl, THE SMALL REMOTE ISLAND that constitutes the easternmost corner of the Polynesian triangle, was found and populated long before the Europeans "discovered" this part ofthe world in 1722. The long-standing questions concern ing this remarkable island are: who were the first to populate the island, at what time was it populated, and did the Rapa Nui population and development on the island result from a single voyage? Over the years there has been much discussion, speculation, and new scientific results concerning these questions. This has resulted in several conferences and numerous scientific and popular papers and monographs. The aim ofthis paper is to present the contemporary views on these issues, drawn from the results of the last 45 years of archaeological research on the island (Fig. 1), and to describe recent fieldwork that Martinsson-Wallin completed on Rapa Nui. Results from the Norwegian Archaeological Expedition to Rapa Nui in 1955 1956 suggest that the island was populated as early as c. A.D. 400 (Heyerdahl and Ferdon 1961: 395). This conclusion was drawn from a single radiocarbon date. This dated carbon sample (K-502) was found in association with the so-called Poike ditch on the east side of the island. The sample derived from a carbon con centration on the natural surface, which had been covered by soil when the ditch was dug. The investigator writes the following: There is no evidence to indicate that the fire from which the carbon was derived actually burned at the spot where the charcoal occurred, but it is clear that it was on the surface of the ground at the time the first loads of earth were carried out of the ditch and deposited over it. -

Department The University of British Columbia 1956 Main Mall Vancouver, Canada V6T 1Y3 Date DE-6(3/81) ABSTRACT The purpose of this thesis is to evaluate whether the Territorial Use- Rights in Fishing (TURFs) of Lake Titieaca, Peru, are effective in overcoming the common property problem of typical fisheries and therefore whether TURFs may prove valuable as part of a more formal management system. It has recently been argued that TURFs should be incorporated into small-scale fisheries management schemes since they should be effective in controlling fishing effort, in promoting a more equitable distribution of the benefits from fishing and in reducing administrative inefficiencies. -

Relación Fenética De Especies Del Orden Poales De Interés Económico En La Laguna El Paraíso, Huacho, 2017
Relación fenética de especies del orden Poales de interés económico en la laguna El Paraíso, Huacho, 2017 Phenetic relationship of Poales species of economic interest in the El Paraíso lagoon, Huacho, 2017 Hermila B. Díaz Pillasca1, Zoila Honorio Durand2, Carmen Rojas Zenozain1, Miguel A. Durand Meza1 RESUMEN Objetivo: Estimar la relación fenética de las especies del orden Poales de interés económico de la laguna El Paraíso, Huacho – 2017. Métodos: Para lo cual se aplicó el diseño de una sola casilla; donde la población estuvo constituida por todos los individuos de las especies seleccionadas; de la cual se extrajo una muestra de 43 individuos, mediante un diseño aleatorio estratificado; eligiéndose 34 caracteres cualitativos y 13 cuantitativos; utilizados para estimar variabilidad y distancia fenética dentro y entre especies, mediante estadística descriptiva, inferencial (ANVA y Tukey) y Taxonomía Numérica, a través del programa Past 3.0. Resultados: Los caracteres cuantitativos de interés económico (longitud de culmo) muestran una baja variabilidad fenotípica (CV < 12%) intra e interespecífica, presumiblemente por influencia ambiental; la distancia fenética intraespecífica es estrecha en las tres especies evaluadas, siendo T. dominguensis, la que muestra mayor número de formas fenotípicas; y, C. laevigatus tiene una mayor distancia fenética con respecto a S. californicus y T. dominguensis; las mismas que son iguales entre sí. Conclusiones: El humedad es una comunidad compleja pero poco estable. Palabras clave: Relación fenética, Poales,
