- I report observations consistent with the interpretation that a Chestnut-collared Longspur (Calcarius ornatus) fledgling from a first brood begged for and received food from its parents at a their second brood nest. All five nestlings in the second brood subsequently died and starvation appeared to be the major factor contributing to their deaths. This is the first reported case of apparent between-brood sibling competition in a passerine species and it fits the criteria of a parent-offspring conflict.

- The value of games as a vehicle for teaching concepts while inspiring students is now well accepted at almost all levels of education. Video games, arcade and computer games are rarely given the same kind of attention. This paper will describe the value of computer games as a motivator and some of the benefits that can be realized by using known computer games as programming applications, even in the first year of a CS program. The use of two such games as assignments in CS1 and CS2 is outlined and some feedback on the experience is offered.

- Road Watch in the Pass is a citizen-science project that engages local citizens in reporting wildlife observations along a 44-km stretch of Highway 3 through Crowsnest Pass in southwestern Alberta, Canada. The numbers of wildlife vehicle collisions and a recent proposal to expand the highway have raised concerns from both human safety and wildlife conservation perspectives. Through the use of a web-based GIS, interested citizens can contribute information that will be instrumental in making final decisions concerning measures to mitigate the effects of highway expansion. Currently, 58 people have contributed over 713 observations to Road Watch. We performed a preliminary comparison of 11...

- The proposed Castle Wilderness (Canada) and the Monarch Butterfly Biosphere Reserve (Mexico) are used to demonstrate the application of a pluridimensional spectrum of governance framework to evaluate the influence of governance on the establishment and management of pro-tected areas. The objectives are to understand (a) the relevant similarities and differences between the two countries, (b) the interactions across governance dimensions, and (c) the factors that influ-ence conservation outcomes. The analysis shows that in both cases protected area governance is affected negatively by weak environmental and economic governance. Public support, funding, and improvements in protected area...

- Before researchers can perform studies using commercial games, they must choose which game or games to study. The manner in which that choice is made and justified is the focus of this paper. Ideally, research informs pedagogy and when looking at game education it is important to be able to justify and defend conclusions drawn from game studies so they can inform best practices in design and development. As the number and sophistication of titles released in a given year continues to rise, it becomes even more important to look more seriously at how we are choosing the games we study, the criteria we use for those studies, how we support our claims about the suitability of the game for...

- Bird collisions with electrical transmission lines are a cause of avian mortality. The exact magnitude of the problem is not known because most avian mortality goes undetected; however, existing mortality estimates make this phenomenon a significant ecological, social and economic concern. Electric utility companies operate thousands of kilometres of transmission line, making it difficult and costly to identify problem sites and prioritize areas for mitigation. Existing research suggests that mortality is not evenly distributed, but spatially clustered in areas with particular combinations of environmental and physical attributes. We used a combination of a geographic information system ...

- Print media is one form of public discourse that provides a means to examine human-coyote interactions. We conducted a content analysis of 453 articles addressing coyote events reported in the Canadian print media between 1998 and 2010. We found 119 articles about human-coyote interactions, of which 32 involved a report of coyote biting (26) or attempting to bite (6) a person. 108 articles were about coyote-dogs and 32 about coyotes-cat interactions. Remaining articles were on topics unrelated to interactions (e.g. culls). Basing our analysis in grounded theory, we identified important descriptive and emotional themes surrounding these events. The most common words describing coyotes were...

- Emerging evidence suggests that ecological heterogeneity across space can influence the genetic structure of populations, including that of long-distance dispersers such as large carnivores. On the central coast of British Columbia, Canada, wolf (Canis lupus L., 1758) dietary niche and parasite prevalence data indicate strong ecological divergence between marine-oriented wolves inhabiting islands and individuals on the coastal mainland that interact primarily with terrestrial prey. Local holders of traditional ecological knowledge, who distinguish between mainland and island wolf forms, also informed our hypothesis that genetic differentiation might occur between wolves from these...

- Many people struggle with the fundamental concepts underlying Mendelian genetics. As soon as we involve more than two traits things get complicated. The classic examples are fine, but additional resources can be helpful. Besides, playing with blood isn't all it's cracked up to be, and rabbits are cuter. Here's a visual way to learn the jargon and the basic principles of Mendelian inheritance while playing a fast-paced card game using rabbit coat color genetics. Coat color in rabbits demonstrates dominance/recessive traits, differences in pheno- vs genotypes, epistatis, and multiple alleles - all of which blend together to form the color we see. Gene Rummy is a variation of Gin Rummy....

- Management of recreational access on public forest lands is a complex issue of growing global importance. The provision of public recreation opportunities is part of the suite of ecological goods and services that must be considered by many forest managers. Effective access management is predicated on understanding the attitudes and perceptions of recreation users in order to predict and influence visitor behaviour and gauge the acceptance of new management strategies. Potential access management strategies vary given the nature of recreation activities and include: restricting the amount, type, and spatial distribution of use, visitor education, temporal restrictions and enhancing site...

- Videogames are interactive by nature - people proceed in games by doing things, and this experiential quality lies at the very core of game design. Without interaction, it isn’t a game. Videogames are popular precisely because of the experience - games designed for learning can do no less. However, to be feasible for use in formal educational settings, they must do more, and while we are making progress studying games in classrooms, there remain few structured approaches to analysing games that do not include classroom testing. This paper outlines the author’s Four Pillars of Game-Based Learning (4PEG) which can be used to perform a structured analysis of both COTS and serious games to...

- Across the foot sole, there are vibration and monofilament sensory differences despite an alleged even distribution of cutaneous afferents. Mechanical property differences across foot sole sites have been proposed to account for these differences. Vibration (VPT; 3 Hz, 40 Hz, 250 Hz), and monofilament (MF) perception threshold measurements were compared with skin hardness, epidermal thickness, and stretch response across five foot sole locations in young healthy adults (n = 22). Perceptual thresholds were expected to correlate with all mechanical property measurements to help address sensitivity differences between sites. Following this hypothesis, the MedArch was consistently found to be...

- Perceptual thresholds are known to vary across the foot sole, despite a reported even distribution in cutaneous afferents. Skin mechanical properties have been proposed to account for these differences; however, a direct relationship between foot sole afferent firing, perceptual threshold, and skin mechanical properties has not been previously investigated. Using the technique of microneurography, we recorded the monofilament firing thresholds of cutaneous afferents and associated perceptual thresholds across the foot sole. In addition, receptive field hardness measurements were taken to investigate the influence of skin hardness on these threshold measures. Afferents were identified as...

- Steady-state tilt has no effect on cerebrovascular reactivity to increases in the partial pressure of end-tidal carbon dioxide (PETCO2). However, the anterior and posterior cerebral circulations may respond differently to a variety of stimuli that alter central blood volume, including lower body negative pressure (LBNP). Little is known about the superimposed effects of head-up tilt (HUT; decreased central blood volume and intracranial pressure) and headdown tilt (HDT; increased central blood volume and intracranial pressure), and LBNP on cerebral blood flow (CBF) responses. We hypothesized that (a) cerebral blood velocity (CBV; an index of CBF) responses during LBNP would not change with...

- Creating a textbook involves ensuring that the content, text, and visual diagrams explain concepts well and as accurately as possible. This includes breaking the text into “bite-sized” palatable chunks that give the students the opportunity to pause, reflect on, and apply what they have learned from each section. The visuals are often just as important as the text; realistic, vibrantly-coloured three-dimensional art is integral for student learning in this subject as it helps to teach the concepts through visualization in addition to theory. The figures must teach well not only on the page, but also when projected on a classroom screen or when viewed on a mobile device. Having a...

- The Crown of the Continent Ecosystem (CCE) encompasses a 72,000 sq. km area of the Rocky Mountains in southwestern Alberta, southeastern British Columbia, and northwestern Montana. Known for its biodiversity, including a full compliment of mammalian carnivores, managing this ecosystem across many jurisdictional boundaries is challenging. With many stakeholders involved in the Crown of Continent Ecosystem, tracking the research being conducted in this area is essential. This publication includes an annotated bibliography of more than 250 research documents published between between 2000-2015 and makes recommendations as to which areas and topics require further study within the Crown of...

- Stimulation of high threshold mechanical nociceptors on the skin can modulate efferent sympathetic outflow. Whether low threshold mechanoreceptors from glabrous skin are similarly capable of modulating autonomic outflow is unclear. Therefore, the purpose of this study was to examine the effects of cutaneous afferent feedback from the hand palm and foot sole on efferent muscle sympathetic nerve activity (MSNA). Fifteen healthy young participants (9 male; 25 ± 3 years [range: 22-29]) underwent microneurographic recording of multi-unit MSNA from the right fibular nerve during 2 minutes of baseline and 2 minutes of mechanical vibration (150Hz, 220μm peak-to-peak) applied to the left hand or...

- Migrations of large ungulates are globally threatened in environments affected by increasing human disturbance, rising large carnivore predation, deteriorating habitat quality, and changing climate. Animals migrating outside of protected areas can be exposed to greater human pressure, and this effect can be stronger when humans are perceived to be a predation risk, such as during hunting seasons. Using four consecutive years of satellite telemetry data (n = 138 migration events), we compared habitat selection, movement, and behavior of a large partially migratory herbivore while migrating through a heterogeneous landscape in spring and fall. We tested the hypothesis that fall hunting...
