The phylum Nematomorpha contains approximately 350 species in 19 extant genera. The genus Gordionus contains 56species, four of which occur in the contiguous United States of America. Here we describe two new Gordionus speciesfrom the southern Rocky Mountains. Worms were collected at three sites in the Santa Fe National Forest in northern NewMexico in the southernmost tip of the Rocky Mountains. Sites consisted of first order streams above 3120m in aspen/pinewoodland. Gordionus lokaaus n. sp. has flat, polygonal or roundish, areoles covering all parts of the body. The male cloa-cal opening is surrounded by broad bristles with stout apexes forming a unique tube-like opening. Adhesive warts aresmall and postcloacal spines are thin and triangular-shaped. Gordionus bilaus n. sp. also has flat polygonal or roundshaped areoles, but has indistinct interareolar furrows making neighboring areoles appear fused. The male cloacal openingis surrounded by stout, finger-like bristles in 2‒3 rows. Adhesive warts are larger and postcloacal spines are broad andmound-shaped. These species double the number known from the state of New Mexico and are the first gordiids described from the southern part of the Rocky Mountains.

Few traveling between Santa Fe, New Mexico, and the Rio Grande valley realize that they are traversing one of the most significant American Indian migration and settlement corridors in the Southwest, a well-watered and fertile floodplain that served to link peoples of the southern Rocky Mountains and the San Juan River to those of the Jemez range and Sangre de Cristo Mountains, and the Rio Grande, across some 300 miles. This chapter gives an overview of Pueblo (Tiwa, Tewa, Towa, Keres, Hopi, and Zuni), Apache, Navajo, and O’odham histories, and reveals a dual process of migration and place making across a millennium. The Southwest has a high variability in seasonal precipitation, and its peoples have demonstrated creative and adaptable cultures that allowed for movement to new locations and the creation of new homelands as a crucial aspect of their survival.

AbstractEvidence from aerial photographs, maps, and field checks indicates that 319 glaciers lie in cirques of the Rocky Mountains, south of the United States-Canadian border. On a subcontinental scale, the distribution of glaciers is highly clustered, with larger and denser clusters located in the northern Rocky Mountains. Lesser concentrations of small glaciers occur in the southern Rocky Mountains. The total area of glaciers in the Rocky Mountains of the U.S.A. is 78.9 km2.

A Review of: Hobbs, K., & Klare, D. (2016). Are we there yet?: A longitudinal look at e-books through students’ eyes. Journal of Electronic Resources Librarianship, 28(1), 9-24. http://dx.doi.org/10.1080/1941126X.2016.1130451 Abstract Objective – To determine undergraduate students’ opinions of, use of, and facility with e-books. Design – A qualitative study that incorporated annual interview and usability sessions over a period of four years. The protocol was informed by interview techniques used in prior studies at Wesleyan University. To supplement the body of qualitative data, the 2014 Measuring Information Service Outcomes (MISO) survey was distributed; the researchers built five campus-specific e-book questions into the survey. Setting – A small university in the Northeastern United States of America. Subjects – 28 undergraduate students (7 per year) who attended summer session between the years of 2011-2014 recruited for interview and usability sessions; 700 full-time undergraduate students recruited for the 2014 MISO survey. Methods – The method was designed by a library consortium in the Northeastern United States of America. The study itself was conducted by two librarians based at the single university. To recruit students for interview and usability sessions, librarians sent invitations via email to a random list of students enrolled in the university’s summer sessions. Recruitment for the 2014 MISO survey was also conducted via email; the survey was sent to a stratified, random sample of undergraduate students in February 2014. Interview sessions were structured around five open-ended questions that examined students’ familiarity with e-books and whether the format supports academic work. These sessions were followed by the students’ evaluation of specific book titles available on MyiLibrary and ebrary, platforms accessible to all libraries in the CTW Consortium. Participants were asked to locate e-books on given topics, answer two research questions using preselected e-books, explain their research process using the above mentioned platforms, and comment on the overall usability experience. Instead of taking notes during interview and usability sessions, the researchers recorded interviews and captured screen activity. Following sessions, they watched recordings, took notes independently, and compared notes to ensure salient points were captured. Due to concerns that a small pool of interview and usability candidates might not capture the overall attitude of students towards e-books, the researchers distributed the 2014 MISO survey between the third and fourth interview years. Five additional campus-specific e-book questions were included. The final response rate was 33%. Main Results – The results of the interviews, usability studies, and MISO survey suggest that although students use print and electronic formats for complementary functions, 86% would still select print if they had to choose between the formats. Findings indicate that e-books promote discovery and convenient access to information, but print supports established and successful study habits, such as adding sticky notes to pages or creating annotations in margins. With that being said, most students do not attempt to locate one specific format over another. Rather, their two central concerns are that content is relevant to search terms and the full-text is readily available. Study findings also suggest that students approach content through the lens of a particular assignment. Regardless of format, they want to get in, locate specific information, and move on to the next source. Also, students want all sources – regardless of format – readily at hand and arranged in personal organization systems. PDF files were the preferred electronic format because they best support this research behaviour; content can be arranged in filing systems on personal devices or printed when necessary. Because of these research habits, digital rights management (DRM) restrictions created extreme frustration and were said to impede work. In some cases, students created workarounds for the purpose of accessing information in a usable form. This included visiting file sharing sites like Pirate Bay in order to locate DRM free content. Findings demonstrated a significant increase in student e-book use over the course of four years. However, this trend did not correspond to increased levels of sophistication in e-book use or facility with build-in functions on e-book platforms. The researchers discovered that students create workarounds instead of seeking out menu options that save time in the long run. This behaviour was consistent across the study group regardless of individual levels of experience working with e-books. Students commented that additional features slow down work rather than creating efficiency. For instance, when keyboard shortcuts used to copy and paste text did not function, students preferred to type out a passage rather than spend time searching for copy functions available on the e-book platform. Conclusion – Academic e-books continue to evolve in a fluid and dynamic environment. While the researchers saw improvements over the course of four years (e.g., fewer DRM restrictions) access barriers remain, such as required authentication to access platform content. They also identified areas where training sessions lead by librarians could demonstrate how e-books support student research and learning activities. The researchers also found that user experiences are local in nature and specific to campus cultures and expectations. They concluded that knowledge of local user communities should drive book format selection. Whenever possible, libraries should provide access to multiple formats to support a variety of learning needs and research behaviours.

D. H. Lawrence’s essays ‘The Spinner and the Monks’ of 1913 and ‘The Hopi Snake Dance’ of 1924 offer evocative textual considerations of aesthetic mediation through acts of the body. In these essays, readers can understand ‘traditional’ aesthetic acts to be those that are not contrivances of modernity; through such acts, history is invoked in the now, as if unchanged. This chapter identifies Lawrence’s engagements with traditional aesthetics as unique experiences of the human sensorium. The examples this chapter examines – the first from Lawrence’s earliest trip outside England (Italy), and the second from New Mexico (in the Southwestern United States) – show how Lawrence progressively experienced and then wrote about ‘traditional’ aesthetic acts as having a unique capacity to engage with community, history and truth. They thus have broad implications concerning Lawrence’s movement toward a refined articulation of aesthetic difference and viscerally mediated relationships. Lawrence’s accounts of Hopi dance and Italian handiwork reveal an openness to the viscerally-mediating capacity of aesthetic experience. As a result of his multi-sensorial engagements, Lawrence experiences and textually records ‘traditional’ aesthetic performances or outputs as both meditating and transformational.
