The implications of the regional haze rule on renewable and wind energy development on Native American lands in the west: Working paper series--02-21

A study conducted at Northern Arizona University investigated the barriers and opportunities facing Native American tribes in the west when considering development of their renewable energy resources in order to reduce regional haze. This paper summarizes some of the findings of that work with special attention to wind energy. Background information is presented concerning the regional haze rule and the western regional air partnership, and some of the circumstances surrounding development of tribal energy resources. An assessment of tribal energy issues revealed that many Native American tribes are interested in developing their renewable resources. However, this development should occur within the context of maintaining and strengthening their cultural, social, economic, and political integrity. Furthermore, it is shown that Native American lands possess an abundant wind resource. A list of potential actions in which tribes may participate prior to or during development of their wind or renewable resources is provided

Economic analysis of energy efficiency measures: Tribal case studies with The Confederated Salish and Kootenai Tribes of The Flathead Reservation, The Pascua Yaqui Tribe, and The Yurok Tribe: Working paper series--04-02

The best way to reduce air pollution from the production of electricity is not to produce it in the first place. This paper presents three cases studies explaining how energy efficiency programs can be beneficial to tribes from a purely cost-saving basis, The Yurok, Flathead and Pascua Yaqui Reservations graciously provided an opportunity to investigate energy efficiency for their tribes. In each case the consumption of electricity was reduced such that a positive net present value was present following an initial capital investment. In the case of the irrigation systems on the Flathead Reservation, the savings were substantial even though no explicit savings of water was accounted for. It is estimated that tribes can reduce electricity costs by 10-50% by following energy efficiency programs. Many programs can be very simple involving small upfront capital outlays, such as changing light bulbs or installing motion sensors. The Yurok case showed a return of 7.5% after simply changing bulbs and the Pasqua Yaqui case showed a possible return of 10-80%. Other tribes could make similar investments and realize similar benefits in addition to improved air quality. The strongest recommendation from the Air Pollution Prevention Forum to tribes was to develop an energy plan. These cases show that some fairly simple analysis can make a plan very beneficial

Recommendations for reducing energy consumption and improving air quality through energy efficiency in Indian Country: Working paper series--04-04

The strongest recommendation stemming from the Air Pollution Prevention forum of the Western Regional Air Partnership (WRAP) was for tribes to develop and implement energy plans. This paper provides a discussion of the benefits of any such plan and itemized a variety of components of any said plan. A brief discussion of the WRAP is presented is the framework of improving air quality. Based on the background of Jacobs (2000) and Smith (2000), the primary and secondary benefits of energy efficiency plans are then discussed. Then a series of specific recommendations are itemized. These include tribally sponsored programs, collaborative opportunities, and tribal leadership programs

The ocean sampling day consortium.

Ocean Sampling Day was initiated by the EU-funded Micro B3 (Marine Microbial Biodiversity, Bioinformatics, Biotechnology) project to obtain a snapshot of the marine microbial biodiversity and function of the world's oceans. It is a simultaneous global mega-sequencing campaign aiming to generate the largest standardized microbial data set in a single day. This will be achievable only through the coordinated efforts of an Ocean Sampling Day Consortium, supportive partnerships and networks between sites. This commentary outlines the establishment, function and aims of the Consortium and describes our vision for a sustainable study of marine microbial communities and their embedded functional traits

Accuracy of Using Visual Identification of White Sharks to Estimate Residency Patterns

Determining the residency of an aquatic species is important but challenging and it remains unclear what is the best sampling methodology. Photo-identification has been used extensively to estimate patterns of animals' residency and is arguably the most common approach, but it may not be the most effective approach in marine environments. To examine this, in 2005, we deployed acoustic transmitters on 22 white sharks (Carcharodon carcharias) in Mossel Bay, South Africa to quantify the probability of detecting these tagged sharks by photo-identification and different deployment strategies of acoustic telemetry equipment. Using the data collected by the different sampling approaches (detections from an acoustic listening station deployed under a chumming vessel versus those from visual sightings and photo-identification), we quantified the methodologies' probability of detection and determined if the sampling approaches, also including an acoustic telemetry array, produce comparable results for patterns of residency. Photo-identification had the lowest probability of detection and underestimated residency. The underestimation is driven by various factors primarily that acoustic telemetry monitors a large area and this reduces the occurrence of false negatives. Therefore, we propose that researchers need to use acoustic telemetry and also continue to develop new sampling approaches as photo-identification techniques are inadequate to determine residency. Using the methods presented in this paper will allow researchers to further refine sampling approaches that enable them to collect more accurate data that will result in better research and more informed management efforts and policy decisions

Chromosome-scale genome assembly provides insights into rye biology, evolution and agronomic potential

Rye (Secale cereale L.) is an exceptionally climate-resilient cereal crop, used extensively to produce improved wheat varieties via introgressive hybridization and possessing the entire repertoire of genes necessary to enable hybrid breeding. Rye is allogamous and only recently domesticated, thus giving cultivated ryes access to a diverse and exploitable wild gene pool. To further enhance the agronomic potential of rye, we produced a chromosome-scale annotated assembly of the 7.9-gigabase rye genome and extensively validated its quality by using a suite of molecular genetic resources. We demonstrate applications of this resource with a broad range of investigations. We present findings on cultivated rye's incomplete genetic isolation from wild relatives, mechanisms of genome structural evolution, pathogen resistance, low-temperature tolerance, fertility control systems for hybrid breeding and the yield benefits of rye-wheat introgressions.Peer reviewe

Treatments for people who use anabolic androgenic steroids: a scoping review.

BACKGROUND: A growing body of evidence suggests that anabolic androgenic steroids (AAS) are used globally by a diverse population with varying motivations. Evidence has increased greatly in recent years to support understanding of this form of substance use and the associated health harms, but there remains little evidence regarding interventions to support cessation and treat the consequences of use. In this scoping review, we identify and describe what is known about interventions that aim to support and achieve cessation of AAS, and treat and prevent associated health problems. METHODS: A comprehensive search strategy was developed in four bibliographic databases, supported by an iterative citation searching process to identify eligible studies. Studies of any psychological or medical treatment interventions delivered in response to non-prescribed use of AAS or an associated harm in any setting were eligible. RESULTS: In total, 109 eligible studies were identified, which included case reports representing a diverse range of disciplines and sources. Studies predominantly focussed on treatments for harms associated with AAS use, with scant evidence on interventions to support cessation of AAS use or responding to dependence. The types of conditions requiring treatment included psychiatric, neuroendocrine, hepatic, kidney, cardiovascular, musculoskeletal and infectious. There was limited evidence of engagement with users or delivery of psychosocial interventions as part of treatment for any condition, and of harm reduction interventions initiated alongside, or following, treatment. Findings were limited throughout by the case report study designs and limited information was provided. CONCLUSION: This scoping review indicates that while a range of case reports describe treatments provided to AAS users, there is scarce evidence on treating dependence, managing withdrawal, or initiating behaviour change in users in any settings. Evidence is urgently required to support the development of effective services for users and of evidence-based guidance and interventions to respond to users in a range of healthcare settings. More consistent reporting in articles of whether engagement or assessment relating to AAS was initiated, and publication within broader health- or drug-related journals, will support development of the evidence base
