In July 2017 members of the DTES community started meeting as a collective at the Hives for Humanity Bee Space to have conversation about how to ensure that community ethics are a respected part of the process of cultural production. We define cultural production as being: any time an entity comes into a community to make a product from its culture. ie. individuals and/or organisations of journalists, film makers, photographers, students, researchers, tourists or volunteers. We define community ethics as being: a set of principles to guide behaviour, based in lived experience, acknowledging the interconnectedness of our humanity, fostering relationships of respect, responsibility, reciprocity and return. We have produced a resource card and a manifesto out of these meetings which we are launching at our event on March 7th 2019, 7pm-9pm at SFU Woodwards. Copies of the card and manifesto will be available for all to take out into the community, and will be open sourced after the event. The evening included a short panel discussion with members of the collective sharing their experiences of cultural production – the good, the bad and the ugly!

Critical theorist Alberto Toscano joins Am Johal in conversation about his work and writings, as he joins SFU as a visiting faculty member with the Digital Democracies Institute in SFU’s School of Communication. In this episode, they discuss Alberto’s writing on the philosophy of fanaticism, and conflicting discourse and counter-histories around the figure of the fanatic, which historically takes many forms, from abolitionist leaders to peasant revolutionaries. Alberto and Am also dive into global and historical trends of authoritarianism, racial capitalism and the notion of ‘late fascism.’ Alberto speaks to expanding our concept of fascism, to recognize iterations outside of what could be thought of as European fascism. They also talk about neoliberal tendencies in post-secondary administration, and the workings of mechanisms that maintain or fortify power structures within institutions.

Understanding how anthropogenic disturbance affects animal behavior is challenging because observational studies often involve co-occurring disturbances (e.g., noise, lighting, and roadways), and laboratory experiments often lack ecological validity. During the 2016 and 2017 avian breeding seasons, we investigated the effects of anthropogenic noise and light on the singing and spatial behavior of wild birds by independently manipulating the presence of each type of disturbance at 89 sites in an otherwise undisturbed boreal forest in Labrador, Canada. Each treatment was surrounded by an 8-channel microphone array that recorded and localized avian vocalizations throughout the manipulation. We analyzed the effects of noise and light on the timing of the first vocalizations of each species at each array during the dawn chorus, and on the proximity of the vocalizing birds to the disturbance when those songs were produced. We analyzed all species combined, and then conducted separate analyses for the six most common species: Boreal Chickadee, Dark-eyed Junco, Ruby-crowned Kinglet, Swainson’s Thrush, White-throated Sparrow, and Yellow-rumped Warbler. When all species were analyzed together, we found that traffic noise attracted vocalizing birds. There was some evidence that light repelled birds, but this evidence was inconsistent. In our species-specific analyses, Yellow-rumped Warbler sang earlier in response to noise; Swainson's Thrush was attracted to noise and the combination of noise and light, but repelled by light alone. Our study provides some of the first experimental evidence of the independent and combined effects of traffic noise and light on the vocal and spatial behavior of wild birds, and suggests that breeding birds may be attracted to noisy roads where they could be exposed to additional forms of disturbance.

There is currently conflict in the literature on the taxonomic status of the reportedly cosmopolitan species Neosiphonia harveyi, a common red alga along the coast of Atlantic Canada and New England, USA. Neosiphonia harveyi sensu lato was assessed using three molecular markers: COI-5P, ITS and rbcL. All three markers clearly delimited three genetic species groups within N. harveyi sensu lato in this region, which we identified as N. harveyi, N. japonica and Polysiphonia akkeshiensis (here resurrected from synonymy with N. japonica). Although Neosiphonia harveyi is considered by some authors to be introduced to the Atlantic from the western Pacific, it was only confirmed from the North Atlantic suggesting it is native to this area. In contrast, Neosiphonia japonica was collected from only two sites in Rhode Island, USA, as well as from its reported native range in Asia (South Korea), which when combined with data in GenBank indicates that this species was introduced to the Northwest Atlantic. The GenBank data further indicate that N. japonica was also introduced to North Carolina, Spain, Australia and New Zealand. Despite the fact that all three markers clearly delimited N. harveyi and N. japonica as distinct genetic species groups, the ITS sequences for some N. harveyi individuals displayed mixed patterns and additivity indicating introgression of nuclear DNA from N. japonica into N. harveyi in the Northwest Atlantic. Introgression of DNA from an introduced species to a native species (i.e. “genetic pollution”) is one of the possible consequences of species introductions, and we believe this is the first documented evidence for this phenomenon in red algae.

The physiological mechanisms underlying local adaptation in natural populations of animals, and whether the same mechanisms contribute to adaptation and acclimation, are largely unknown. Therefore, we tested for evolutionary divergence in aerobic exercise physiology in laboratory bred, size-matched crosses of ancestral, benthic, normal Lake Whitefish (Coregonus clupeaformis) and derived, limnetic, more actively-swimming ‘dwarf’ ecotypes. We acclimated fish to constant swimming (emulating limnetic foraging) and control conditions (emulating normal activity levels) to simultaneously study phenotypic plasticity. We found extensive divergence between ecotypes: dwarf fish generally had constitutively higher values of traits related to oxygen transport (ventricle size) and use by skeletal muscle (percent oxidative muscle, mitochondrial content), and also evolved differential plasticity of mitochondrial function (Complex I activity and flux through Complexes I-IV and IV). The effects of swim-training were less pronounced than differences among ecotypes and the traits which had a significant training effect (ventricle protein content, ventricle MDH activity and muscle Complex V activity) did not differ among ecotypes. Only one trait, ventricle mass, varied in a similar manner with acclimation and adaptation and followed a pattern consistent with genetic accommodation. Overall, the physiological and biochemical mechanisms underlying acclimation and adaptation to swimming activity in Lake Whitefish generally differ.

The performance of courtship signals provides information about the behavioural state and quality of the signaller, and females can use such information for social decision-making (e.g. mate choice). However, relatively little is known about the degree to which the perception of and preference for differences in motor performance are shaped by developmental experiences. Furthermore, the neural substrates that development could act upon to influence the processing of performance features remains largely unknown. In songbirds, females use song to identify males and select mates. Moreover, female songbirds are often sensitive to variation in male song performance. Consequently, we investigated how developmental exposure to adult male song affected behavioural and neural responses to song in a small, gregarious songbird, the zebra finch. Zebra finch males modulate their song performance when courting females, and previous work has shown that females prefer the high-performance, female-directed courtship song. However, unlike females allowed to hear and interact with an adult male during development, females reared without developmental song exposure did not demonstrate behavioural preferences for high-performance courtship songs. Additionally, auditory responses to courtship and non-courtship song were altered in adult females raised without developmental song exposure. These data highlight the critical role of developmental auditory experience in shaping the perception and processing of song performance.
