Pipeline operators, contractors and governments face important challenges when planning, designing, constructing and operating pipelines which connect the hydrocarbon reserves in the Amazonian basin with population and shipping centers on the Pacific coast. These pipelines cross portions of the Amazonian rainforest, the mountain rainforest along the eastern flank of the Andes, the Andean plateau, and the rural and urban low lying desert areas along the Pacific coast. The need for these pipelines will continue and offers a tremendous opportunity to promote sustainable economic development. However, there are several challenges in safeguarding the integrity of the pipeline, environment, local population, and socio-economic fabric of the region. Failure to properly address these risks could have significant financial, engineering, environmental and social, or reputational consequences for operators, contractors, financiers and governments. In this context, companies need to understand the specific challenges present and implement an encompassing project and risk management strategy that entails leadership, team work, effective communication and collaboration in a manner that proactively meets anticipated needs and responds to evolving conditions. During design and construction management, engineers and scientists are challenged by geology, topography, limited or no field data, limited access to the right-of-way (RoW), and socio-environmental aspects. Major training efforts are needed for the construction workforce, in a manner applicable to educational and cultural characteristics. Special road safety measures are required and in many instances the right-of-way will be the only means of transporting construction material. Other special logistical challenges are presented by the rich cultural history of the Andes. During operation, special consideration needs to be given to external natural hazards like landslides, soil creep, seismicity, and river scour. Management needs to maintain good communication with all parties affected by the project and proactively promote broad socio-economic development in the project area. The recognition of these specific challenges and upfront investment will facilitate mutually beneficial project advancement and be of particular benefit in instances of anticipatable but uncontrollable events. This paper describes several of these challenges and provides guidance on how to minimize project specific risks and adverse effects to society and environment.

Short description (Adapted from introductory paragraph):“Since the early 90s of the 20th century, I followed systematically the development of the socio-cultural and ethno-political situation in the Andean region, meaning the countries in West South America, whose territories include the Pacific coast, and extend into the Andes. The main area of my anthropological investigations relates to three countries, namely to Ecuador, Bolivia and Peru. Despite the fundamental differences in economic development and particular political differences that can be observed, these countries have much in common. This allows me to treat this region as a single cultural entity and to compare similarities between processes taking place here…” Translated and adapted by Michal Gilewski

The California milliped genus Xystocheir Cook, occurring along the Pacific Coast and the western slope of the Sierra Nevada, comprises nine species, three being divided into a total of seven subspecies; the species are combined into four species-groups named for the oldest component. Xystocheir dissecta (Wood), abundant around San Francisco – San Pablo and Monterey bays, comprises intergrades, one true subspecies, and two apparent semispecies that are treated as subspecies; additionally, a local population in southern Mendocino County has achieved reproductive isolation and attained species status. Two new combinations, X. reducta (Causey) and X. modestior (Chamberlin), are proposed, along with the following new synonymies: Paimokia Chamberlin under Xystocheir, X. acuta Cook, X. francisca and X. milpitas, both by Chamberlin, and Cheirauxus sapiens Chamberlin under X. d. dissecta, new status; and Delocheir conservata and D. dalea, both by Chamberlin, under X. dissecta taibona Chamberlin, new status. The following new species-group taxa are diagnosed: the subspecies Xystocheir dissecta microrama, Xystocheir modestior haerens, and Xystocheir stolonifera uncinata, and the species X. prolixorama, X. solenofurcata, X. brachymacris, X. stenomacris, X. bistipita, and X. stolonifera.

The Astyanax orthodus species-group includes nine species: Astyanax boliviensis sp. nov., A. bopiensis nom. nov., A. embera sp. nov., A. gandhiae sp. nov., A. moorii comb. nov., A. orthodus, A. superbus, A. villwocki and A. yariguies comb. nov. The group is diagnosed by the presence of a series of pinnate-shaped marks (chevrons) located along the lateral midline, which extends from the humeral region to the caudal peduncle. Astyanax bopiensis nom. nov. is proposed as a substitute name for Astyanacinus multidens, which, along with Astyanax yariguies comb. nov., we reassign to Astyanax.We also propose the synonymy of Astyanacinus with Astyanax. The members of the A. orthodus species-group are distributed in northwestern South America, occurring in the Patia River drainage (A. embera sp. nov.) of the Pacific coast of Colombia, the Atrato River Basin (A. orthodus), the Magdalena River Basin (A. yariguies comb. nov.) of Caribbean Colombia, streams of the southern flank of the Andes of the Orinoco Basin in Venezuela (A. superbus), in the upper Amazon River Basin of Colombia, Ecuador and Peru (A. villwocki, A. gandhiae sp. nov.), from the upper Paraguay River (A. moorii comb. nov.), the Madidi and Mamore Rivers, Bolivia (A. boliviensis sp. nov. and A. bopiensis nom. nov.). All species currently included in Astyanacinus are reassigned to the Astyanax orthodus species-group.

ABSTRACTStudies of Native South American genetic diversity have helped to shed light on the peopling and differentiation of the continent, but available data are sparse for the major ecogeographic domains. These include the Pacific Coast, a potential early migration route; the Andes, home to the most expansive complex societies and to one of the most spoken indigenous language families of the continent (Quechua); and Amazonia, with its understudied population structure and rich cultural diversity. Here we explore the genetic structure of 177 individuals from these three domains, genotyped with the Affymetrix Human Origins array. We infer multiple sources of ancestry within the Native American ancestry component; one with clear predominance on the Coast and in the Andes, and at least two distinct substrates in neighboring Amazonia, with a previously undetected ancestry characteristic of northern Ecuador and Colombia. Amazonian populations are also involved in recent gene-flow with each other and across ecogeographic domains, which does not accord with the traditional view of small, isolated groups. Long distance genetic connections between speakers of the same language family suggest that languages had spread not by cultural contact alone. Finally, Native American populations admixed with post-Columbian European and African sources at different times, with few cases of prolonged isolation. With our results we emphasize the importance of including under-studied regions of the continent in high-resolution genetic studies, and we illustrate the potential of SNP chip arrays for informative regional scale analysis.

Abstract Camisea Pipeline Transportation System (PTS) in Peru, owned by Transportadora de Gas del Perú (TGP) and operated by Compañía Operadora de Gas (COGA), begins in the Amazon rainforest, crosses the Andes Mountains (4850msnm) and finally descends towards the Pacific coast. The PTS has been operating for more than 10 years and it has Natural Gas (NG) and Natural Gas Liquids (NGL) transportation pipelines. The NG pipeline is 888km long which includes two Loops (105km and 18km in the coast and mountain sectors, respectively). NGL pipeline is 557km long. From the beginning (0 km) to 210 km, the Right of Way (RoW) is located in the geotechnical context of the Amazon rainforest. Then, between km 210 and km 420, the PTS crosses the mountain chain of the Andes. Finally, between km 420 and Km 730 the RoW is located on the Peruvian Pacific coast. TGP’s operation of the PTS identifies, analyzes and controls the different types of threats that can affect the integrity of the pipelines. The operation is developed according to international standards defined in the Pipeline Integrity Management (PIM) of the operation. Consequently, hazards such as Third Party Damage (TPD), geohazard, external and internal corrosion, among others, are analyzed. However, associated to the economic growth and development of Peru, there have been some cases where the intervention of a person, community or industrial activity in the surroundings of the RoW has resulted in the level of geohazards are spontaneously modified and activated. Consequently, the degree of stability of the RoW is necessary to analyze the integrity of the NG and NGL pipelines. This article describes the occurrence of some practical cases where there was a change in the stability of the RoW of the TGP’s PTS triggered by activities related to TPD. It is highlighted that the identification, analysis, definition and execution of mitigation actions are carried out in a transversal way which involves the participation of different operational areas such as: Integral Maintenance, Geotechnics, Integrity, Social Management, among others. All the activities are done with the approach of keeping the balance between community, environment and infrastructure. Some of the cases considered are: Flood and scour of the RoW triggered by the failure of a water tank in an industrial area, scour of channels due the obstructions and an unstable slope process generated by constructions near the RoW. Today, the operation develops activities in order to mitigate geohazards generated by TPD. Some of these activities are, among others: Social awareness, technical talks, agreements with industrial and local administration entities, geotechnical maintenance and monitoring. In addition, it is highlighted that all the mentioned mitigation actions are carried out in a transversal manner between different operational areas. Afterward, the collected information is properly saved in the Geographic Information System database.

A redescription of Pagurus albus (Benedict, 1892) is presented together with a description of a new species of hermit crab, Pagurus pseudoalbus sp. n., from the Pacific coast of Costa Rica. Pagurus pseudoalbus sp. n. differs from P. albus and P. perlatus by the length of antennal acicles, which do not exceed the distal margin of the 4th antennal segment, whereas in the latter two species, the antennal acicles exceed the 4th antennal segment; the antennular peduncle is proportionally longer than the ocular peduncle in the new species compared to P. perlatus, but shorter than in P. albus; the palm of the right cheliped in P. pseudoalbus sp. n. is 1.3 times as long as broad, while in P. albus and P. perlatus it is 1.0 and 1.4 times as long as broad, respectively. Including the new species, the genus Pagurus in the Eastern Tropical Pacific currently includes 16 species.

The term control used to be central to the scholarship on modern water management. More recently, however, scholars have remarked that the world is too unstable and capricious for control to ever fully succeed. They propose that technologically facilitating water to flow depends instead on care. Building on this, we here propose that holding on to a single catch-all theoretical concept, even if it is ‘care’, does not suffice. Instead, analytical terms are better adapted – and re-adapted to local specificities. To exemplify this, we here present the case of the Huallabamba, a canal that makes horticulture possible in the arid valley of Motupe on the Pacific coast of northern Peru. In this case, while ‘control’ was hard to find, ‘care’ took different forms: the tinkering that compensates for the not-quite-modern character of the infrastructures; the adaptive managerial style necessary given the absence of information; the watchful, hands-on cuidar of the men who walk along the canal high up in the Andes, repairing what is broken, cautious lest they anger the spirits; the listening to and singing for water in the catchment area; and the activism that resists the invasion of mining companies. This open-ended list is not meant to travel as a theoretical grid, but rather to inspire others to propose locally salient analytical terms to explore the sites and situations in which they are involved.

The success of Balfour, Guthrie and Company in mobilizing British and American capital for productive investment contributed importantly to the economic development of the Pacific-coast region of the United States. The changing economic patterns of that region emerge through Professor Rothstein's analysis of the firm and its managers' actions and responses, from which a broader understanding of the problems and direction of foreign investment in the American West is possible.
