Camera trap arrays improve detection probability of wildlife: Investigating study design considerations using an empirical dataset.

Camera trapping is a standard tool in ecological research and wildlife conservation. Study designs, particularly for small-bodied or cryptic wildlife species often attempt to boost low detection probabilities by using non-random camera placement or baited cameras, which may bias data, or incorrectly estimate detection and occupancy. We investigated the ability of non-baited, multi-camera arrays to increase detection probabilities of wildlife. Study design components were evaluated for their influence on wildlife detectability by iteratively parsing an empirical dataset (1) by different sizes of camera arrays deployed (1-10 cameras), and (2) by total season length (1-365 days). Four species from our dataset that represented a range of body sizes and differing degrees of presumed detectability based on life history traits were investigated: white-tailed deer (Odocoileus virginianus), bobcat (Lynx rufus), raccoon (Procyon lotor), and Virginia opossum (Didelphis virginiana). For all species, increasing from a single camera to a multi-camera array significantly improved detection probability across the range of season lengths and number of study sites evaluated. The use of a two camera array increased survey detection an average of 80% (range 40-128%) from the detection probability of a single camera across the four species. Species that were detected infrequently benefited most from a multiple-camera array, where the addition of up to eight cameras produced significant increases in detectability. However, for species detected at high frequencies, single cameras produced a season-long (i.e, the length of time over which cameras are deployed and actively monitored) detectability greater than 0.75. These results highlight the need for researchers to be critical about camera trap study designs based on their intended target species, as detectability for each focal species responded differently to array size and season length. We suggest that researchers a priori identify target species for which inference will be made, and then design camera trapping studies around the most difficult to detect of those species

Long Term Benefits for Women in a Science, Technology, Engineering, and Mathematics Living-Learning Community

Science, technology, engineering and math (STEM) degrees provide opportunities for economic mobility. Yet women, underrepresented minority (URM), and first-generation college students remain disproportionately underrepresented in STEM fields. This study examined the effectiveness of a living-learning community (LLC) for URM and first-generation first-year women interested in STEM. The authors utilized a matched sample post-hoc analysis to examine undergraduate and graduate degree attainment in science related fields for women who participated in the Women in Science Residence Program (WISERP) LLC compared to matched controls. The control group was matched on twelve characteristics that are associated with retention in STEM. First-generation college students in the LLC were significantly more likely to receive an undergraduate degree in science; URM students were more likely to receive an undergraduate degree in a science related field, nearly three times as likely to receive a master’s degree in science and more than three times as likely to receive a graduate degree in science compared to their matched controls. The results indicate that a one-year intervention can meaningfully impact persistence of at-risk populations in attaining STEM bachelor’s degrees and in enrolling in STEM graduate programs and invite further investigation into the factors contributing to the beneficial impact of LLCs

Structural Optimization and Thermal Modeling of Flux Switching Machine

The point of this study was to model a lumped parameter thermal network for flux switching machine. The model could be utilized to outline new cooling systems and as a developer for this sort of machines. The model developed is a thermal framework having segments essentially focused around existing literature. The losses in various machine sections were thought to have already found from the electromagnetic model. The elemental model can then be utilized to carry out simulations regarding cyclic loading as well as transient activities. The thermal model examined here is partitioned into different sectors, thereby empowering analysis of this machine. The model under investigation has been acknowledged by utilizing a COMSOL Multi-physics simulator and Matlab ® programming software. The heat exchange coefficients are characterized from information gathered from the comparative kind of machines. The developed framework also considers sensitivity analysis in terms of parametric effects on the behavior of the machine thermally. The developed model needs no substantial computing and can simply be run on a personal computer. The model can later be modified and connected to diverse machine developments. Structural topology optimization approach is adopted to find the optimal geometry. As a basic study, two optimization techniques i.e., genetic and simulated annealing algorithms have been adopted with the former based on the process of natural selection and the latter on the process of annealing (heating and cooling of metals). The design goal is to minimize the total dissipated losses to improve the overall efficiency and hence to achieve optimal design results

The Effect of Insecticide Synergists on the Response of Scabies Mites to Pyrethroid Acaricides

Synergists are commonly used in combination with pesticides to suppress metabolism-based resistance and increase the efficacy of the agents. They are also useful as tools for laboratory investigation of specific resistance mechanisms based on their ability to inhibit specific metabolic pathways. To determine the role of metabolic degradation as a mechanism for acaricide resistance in human scabies, PBO (piperonyl butoxide), DEF (S,S,S-tributyl phosphorotrithioate) and DEM (diethyl maleate) were used with permethrin as synergists in a bioassay of mite killing. A statistically significant difference in survival time of permethrin-resistant Sarcoptes scabiei variety canis was noted when any of the three synergists were used in combination with permethrin compared to survival time of mites exposed to permethrin alone (p<0.0001). These results indicate the potential utility of synergists in reversing tolerance to pyrethroid-based acaricides (i.e. the addition of synergists to permethrin-containing topical acaricide cream commonly used to treat scabies). To further verify specific metabolic pathways being inhibited by these synergists, enzyme assays were developed to measure esterase, glutathione S-transferase (GST) and cytochrome P450 monooxygenase activity in scabies mites. Results of in vitro enzyme inhibition experiments showed lower levels of esterase activity with DEF; lower levels of GST activity with DEM and lower levels of cytochrome monooxygenase activity with PBO. These findings indicate a metabolic mechanism as mediating pyrethroid resistance in scabies mites

A late 19th-Century British perspective on modern foreign language learning, teaching, and reform: the legacy of Prendergast’s “Mastery System”

The late 19th century saw a great rise in private foreign language learning and increasing provision of Modern foreign language teaching in schools. Evidence is presented to document the uptake of innovations in Thomas Prendergast’s (1807–1886) “Mastery System” by both individual language learners and educationalists. Although it has previously been suggested that Prendergast’s method failed to have much impact, this study clearly demonstrates the major influence he had on approaches to language learning and teaching in Britain and around the world both with his contemporaries and long after his death. This detailed case study illuminates the landscape of modern language pedagogy in Victorian Britain

Differential genomic targeting of the transcription factor TAL1 in alternate haematopoietic lineages

Expression of the basic helix-loop-helix transcription factor TAL1/SCL is required for erythrocyte differentiation; aberrant expression in lymphoid cells leads to oncogenic transformation. Here, global analysis of TAL1 binding in erythroid and malignant T cells identifies cell type specific functional interaction with the transcription factors RUNX and ETS1
