    Systematic relationships of gray wolves (Canis lupus) in southwestern North America

    Get PDF
    We examined specimens of five subspecies of gray wolves from southwestern North America and assessed their systematic affinities using both univariate and multivariate statistical procedures. Because wolves exhibit considerable sexual dimorphism the sexes were separated for the analyses. Principal components analyses revealed considerable overlap among the individuals, but tended to separate the Mexican wolf (C. l. baileyi) from northern wolves (C. l. youngi). Specimens from other subspecies were intermediate to these two. Discriminant function analyses using various groupings of wolves supported these results. Within the southwestern part of North America, we recognize only three subspecies: C. l. baileyi, C. l. youngi, and C. l. nubilus. Wolves formerly assigned to C. l. mogollonensis and C. l. monstrabilis are referred to C. l. baileyi. As an adjunct to our study, we compared recently collected specimens and captive animals with target groups from the southwest. Recent specimens show clear affinities with C. l. baileyi. Captives, although closest to baileyi, show some tendencies. toward dogs, but whether these tendencies are from hybridization or from the effects of captivity is unknown

    How Accurate Is Students’ Self Assessment Of Computer Skills?

    Self-evaluation by students is commonly used as a key element in program and course assessment plans. Such instruments are intended to provide crucial feedback for program improvement and thus play a significant role in closing our assessment loop. For many of the program outcomes, self-assessment by current students and graduates augments other, more objective measures. However, for some outcomes there are no practical means of obtaining objective assessment and we must rely on self-assessment. The heavy reliance on this metric begs the question “How accurate is student self-assessment?” This paper provides data from a second-semester engineering course in which students develop proficiency using computer tools to solve typical engineering problems. Students’ self-assessments in several areas are compared with the instructor’s assessment of these students. Some work reported in the literature addresses the accuracy of student self-assessment in specific academic areas. In the medical field, literature exists which addresses medical students’ selfassessment of specific skills. Other comparisons have been published to compare students’ expected grades with actual results. Little was found that is relevant to engineering student and in particular to their assessment of professional skills. The work reported here relates to the assessment of ABET’s program outcome k: “an ability to use the techniques, skills and modern engineering tools necessary for engineering practice. Methods of Engineering Analysis is a course taken by all engineering majors during their second semester at the University of New Haven. In this course, students are introduced to engineering topics and a variety of numerical methods for solving these problems. The current platform used is a spreadsheet with Visual Basic for Applications programming. Students complete a 30- question survey the first day of class in which they rate their expertise in three broad categories: basic spread-sheet usage, advanced spread-sheet usage and programming. The same survey is completed at the end of the class, thus providing a pre and post view from the students perspective. Quizzes given throughout the course and the final exam were structured to enable instructors to assess student performance in these same areas with composite measures. Data is presented to compare the instructor assessment of performance with students’ self-assessment at the individual level

    The Current Generation of Integrated Engineering Curriculum

    Get PDF
    In September of 2004 our university adopted the Multidisciplinary Engineering Foundation Spiral Curriculum as the basis for disciplinary engineering programs in Chemical, Civil, Electrical, Mechanical and General Engineering. The curriculum includes a sequence of first and second year engineering courses, matched closely with the development of students’ mathematical sophistication and analytical capabilities and integrated with course work in the sciences. Students develop a conceptual understanding of engineering basics in this series of courses which stress practical applications of these principles. The new curriculum was designed to provide students with a multidisciplinary perspective while developing basic engineering skills and fostering an understanding of basic engineering concepts. Each of the ten courses in the program were developed and are taught by faculty from several disciplines. Course materials are intended to make students keenly aware of the highly integrated nature of the current practice of engineering. It was also expected that the novel program would prove to be attractive to a broader range of students than those drawn to traditional disciplinary programs. Finally, student retention was expected to be enhanced by the new courses. Students who entered as freshmen in 2004 are currently juniors, taking courses in their disciplinary major. This study attempts to provide early data on the success of the program through the following measures: ‱ Impact of the new curriculum on student recruiting through a survey of newly matriculated students ‱ Impact on student retention from first to second and second to third years ‱ Comparison of student performance in early disciplinary courses with that of students in previous years ‱ Impact of program implementation on faculty attitude

    Taxonomic status of Myotis occultus

    Get PDF
    The taxonomic status of the Arizona myotis (Myotis occultus) is uncertain. Although the taxon was described as a distinct species and currently is regarded as such by some authors, others have noted what they interpreted as intergradation with the little brown bat (M. lucifugus carissima) near the Colorado-New Mexico state line. In this study, we used protein electrophoresis to compare bats of these nominal taxa. We examined 20 loci from 142 specimens referable to M. occultus and M. lucifugus from New Mexico, Colorado, and Wyoming. Nine of the 20 loci were polymorphic. Results show that there were high similarities among samples, no fixed alleles, and minor divergence from Hardy-Weinberg equilibrium. Our results suggest that the two nominal taxa represent only one species and that M. occultus should be regarded as a subspecies of M. lucifugus

    Stable Hydrogen Isotope Analysis of Bat Hair as Evidence for Seasonal Molt and Long-Distance Migration

    Get PDF
    Although hoary bats (Lasiurus cinereus) are presumed to be migratory and capable of long-distance dispersal, traditional marking techniques have failed to provide direct evidence of migratory movements by individuals. We measured the stable hydrogen isotope ratios of bat hair (∂Dh) and determined how these values relate to stable hydrogen isotope ratios of precipitation (∂Dp). Our results indicate that the major assumptions of stable isotope migration studies hold true for hoary bats and that the methodology provides a viable means of determining their migratory movements. We present evidence that a single annual molt occurs in L. cinereus prior to migration and that there is a strong relationship between ∂Dh and ∂Dp during the molt period. This presumably reflects the incorporation of local ∂Dp into newly grown hair. Furthermore, we present evidence that individual hoary bats are capable of traveling distances in excess of 2,000 km and that hair is grown at a wide range of latitudes and elevations. Stable hydrogen isotope analysis offers a promising new tool for the study of bat migration

    Seasonality and predictability shape temporal species diversity

    Get PDF
    Temporal environmental fluctuations, such as seasonality, exert strong controls on biodiversity. While the effects of seasonality are well known, the predictability of fluctuations across years may influence seasonality in ways that are less well understood. The ability of a habitat to support unique, non‐nested assemblages of species at different times of the year should depend on both seasonality (occurrence of events at specific periods of the year) and predictability (the reliability of event recurrence) of characteristic ecological conditions. Drawing on tools from wavelet analysis and information theory, we developed a framework for quantifying both seasonality and predictability of habitats, and applied this using global long‐term rainfall data. Our analysis predicted that temporal beta diversity should be maximized in highly predictable and highly seasonal climates, and that low degrees of seasonality, predictability, or both would lower diversity in characteristic ways. Using stream invertebrate communities as a case study, we demonstrated that temporal species diversity, as exhibited by community turnover, was determined by a balance between temporal environmental variability (seasonality) and the reliability of this variability (predictability). Communities in highly seasonal mediterranean environments exhibited strong oscillations in community structure, with turnover from one unique community type to another across seasons, whereas communities in aseasonal New Zealand environments fluctuated randomly. Understanding the influence of seasonal and other temporal scales of environmental oscillations on diversity is not complete without a clear understanding of their predictability, and our framework provides tools for examining these trends at a variety of temporal scales, seasonal and beyond. Given the uncertainty of future climates, seasonality and predictability are critical considerations for both basic science and management of ecosystems (e.g., dam operations, bioassessment) spanning gradients of climatic variability

    A Synoptical Classification of the Bivalvia (Mollusca)

    Get PDF
    The following classification summarizes the suprageneric taxono-my of the Bivalvia for the upcoming revision of the Bivalvia volumes of the Treatise on Invertebrate Paleontology, Part N. The development of this classification began with Carter (1990a), Campbell, Hoeks-tra, and Carter (1995, 1998), Campbell (2000, 2003), and Carter, Campbell, and Campbell (2000, 2006), who, with assistance from the United States National Science Foundation, conducted large-scale morphological phylogenetic analyses of mostly Paleozoic bivalves, as well as molecular phylogenetic analyses of living bivalves. Dur-ing the past several years, their initial phylogenetic framework has been revised and greatly expanded through collaboration with many students of bivalve biology and paleontology, many of whom are coauthors. During this process, all available sources of phylogenetic information, including molecular, anatomical, shell morphological, shell microstructural, bio- and paleobiogeographic as well as strati-graphic, have been integrated into the classification. The more recent sources of phylogenetic information include, but are not limited to, Carter (1990a), Malchus (1990), J. Schneider (1995, 1998a, 1998b, 2002), T. Waller (1998), Hautmann (1999, 2001a, 2001b), Giribet and Wheeler (2002), Giribet and Distel (2003), Dreyer, Steiner, and Harper (2003), Matsumoto (2003), Harper, Dreyer, and Steiner (2006), Kappner and Bieler (2006), Mikkelsen and others (2006), Neulinger and others (2006), Taylor and Glover (2006), KĆ™Ă­ĆŸ (2007), B. Morton (2007), Taylor, Williams, and Glover (2007), Taylor and others (2007), Giribet (2008), and Kirkendale (2009). This work has also benefited from the nomenclator of bivalve families by Bouchet and Rocroi (2010) and its accompanying classification by Bieler, Carter, and Coan (2010).This classification strives to indicate the most likely phylogenetic position for each taxon. Uncertainty is indicated by a question mark before the name of the taxon. Many of the higher taxa continue to undergo major taxonomic revision. This is especially true for the superfamilies Sphaerioidea and Veneroidea, and the orders Pectinida and Unionida. Because of this state of flux, some parts of the clas-sification represent a compromise between opposing points of view. Placement of the Trigonioidoidea is especially problematic. This Mesozoic superfamily has traditionally been placed in the order Unionida, as a possible derivative of the superfamily Unionoidea (see Cox, 1952; Sha, 1992, 1993; Gu, 1998; Guo, 1998; Bieler, Carter, & Coan, 2010). However, Chen Jin-hua (2009) summarized evi-dence that Trigonioidoidea was derived instead from the superfamily Trigonioidea. Arguments for these alternatives appear equally strong, so we presently list the Trigonioidoidea, with question, under both the Trigoniida and Unionida, with the contents of the superfamily indicated under the Trigoniida.Fil: Carter, Joseph G..
