Crumble (Live Performance)
<p>This piece captures the mind splitting apart in attempts to reconcile abuse spiritually and intellectually. The overwhelming anxiety and self-blame give the impression of swimming through memories and fragments of the brain, unable to find a solid footing to concentrate. Some lines are emotionally charged; others intellectualise the experience to neutralise the emotional content. A final layer is taken from a Somatic Experiencing exercise, a trauma-informed therapy developed by Peter Levine. This text is a reconciliation and reaffirming text to reintegrate and own body, mind, and space for the damaged person. The text works through the different states and layers of thought that can arise following sexual trauma. This work was inspired by Laetitia Sonami’s <em>Dreams of Control, Dreams of Chaos </em>(2014) keynote presentation at NIME2014.</p> <p>Individual lines of audio are played through different speakers. Audience members may walk around the space as the performer adds other live text layers. Every text layer is kept in place for the folio submission and added to the final output. In the performance, the player walks around the space delivering a monologue relating to the speaker most audible to them. The monologue is captured and distorted through granular synthesis (grabbing, spatialising, and releasing text). As the piece progresses, it becomes more textually complex. The live monologue most frequently dealt with the nature of reality, gaslighting and manipulation tactics used by abusers, sexual abuse and harassment statistics, therapy processes, and the process of turning these thoughts into a recursive work.</p> <p>There is a confessional undertone, a voyeuristic experience into the inner workings of one’s mind. Authentic moments of pain were captured from discussions, used in this work, and layered with research conducted while attempting to cope through prolonged investigations. The ugly story is more authentic, sometimes than the aesthetically beautiful, so attempting to be elegant in the ugliness of the story and true to the feeling of hopefulness and being overwhelmed and trying to hold on by holding on to the rational and not the emotional.</p> <p>Music and choreography by Sophie Rose</p> <p>Audio by Sophie Rose and Cloud Unknowing</p> <p>Videography and Video Editing by Sam L'Huillier</p>

Cost of living squeeze
<p><span>Climate warming can induce a ‘cost-of-living squeeze’ in ectotherms by increasing energetic expenditures while reducing foraging gains. We used biophysical models (validated by 2,685 field observations) to test this hypothesis for ten ecologically diverse lizards in African and Australian deserts. Historical warming (1950-2020) has been more intense in Africa than in Australia, translating to an energetic ‘squeeze’ for African diurnal species, no net impact on Australian diurnal species, but generating an energetic ‘relief’ (by increasing foraging time) for nocturnal species. Future warming impacts will be more severe in Africa than in Australia, especially in summer, requiring increased rates of food intake (+10% per hour active for diurnal species). The effects of climate warming on energy budgets of desert lizards will be species-specific but predictable.</span></p>

<p><strong>Impact of Content and Emotion Congruency on Tipping: Evidence from Live Streaming</strong></p>
Data from: A phylogenetic and morphologic context for the radiation of an endemic fauna in a long-lived lake: Corbulidae (Bivalvia; Myoida) in the Miocene Pebas Formation of western Amazonia
The Corbulidae are one of a handful of a primarily marine bivalve clades that exhibit a remarkable radiation, marked by increased species richness and divergent morphologies, within a long-lived lake. For corbulids, this diversification occurred within the lower to middle Miocene Pebas Formation of western Amazonia. Only one taxon associated with this radiation (Anticorbula) remains extant. We conducted a series of phylogenetic analyses to characterize diversification of Corbulidae within the Pebas Formation and relate that diversification to geologically older freshwater corbulids from the Paleocene Fort Union Formation of the northern Great Plains (United States). We used these results, as well as a quantitative examination of morphospace occupation, to infer whether Pebasian corbulids represent a true species flock, and whether the lacustrine system represented by the Pebas Formation represents a cradle of, or reservoir for, freshwater corbulid diversity. We conducted two sets of phylogenetic analyses using shell morphology characters. A genus-level data set incorporated type species of freshwater corbulid genera, any Paleocene representatives of these genera, and selected brackish and marine corbulid genera. A species-level analysis added all described freshwater corbulid taxa to the genus-level matrix. Our results were highly resolved (few most-parsimonious trees), but not particularly robust (low branch support). For the genus-level matrix, we used a taxon jackknife procedure to explore the effects of taxon sampling on tree stability and topology. Jackknife results recover a subclade of freshwater taxa (including both Anticorbula and Pachydon species and the Paleocene Ostomya sp.) in 92.4% of trees, although placement of this subclade across the ingroup varies, as do the topologic positions of other freshwater species. Freshwater and marine corbulids also are morphologically distinct from each other, a factor that likely reduced the robustness of our phylogenetic results. By combining these results with paleoecologic, stratigraphic, and morphologic data, we infer that freshwater corbulids arose once within the family, prior to the Cenozoic, with three distinct freshwater lineages present at their first appearance in the late Paleocene of North America. Within the Miocene Pebas system of South America, we reconstruct supralimital morphologic evolution within three lineages as freshwater taxa became variously adapted to the fluid, dysoxic muds characterizing lake-bottom facies representative of the Pebas lacustrine system. In addition, corbulids apparently successfully coped with high predation pressures from co-occurring shellcrushing predators. Finally, we consider that freshwater Corbulidae were primarily fluvial taxa throughout their geologic history, with a relatively ephemeral radiation within the Pebasian lake system, thus making the Pebasian system a cradle of diversity for several corbulid lineages.
Data from: Phylogeny and biogeography of the American live oaks (Quercus subsection Virentes): a genomic and population genetics approach
The nature and timing of evolution of niche differentiation among closely related species remains an important question in ecology and evolution. The American live oak clade, Virentes, which spans the unglaciated temperate and tropical regions of North America and Mesoamerica, provides an instructive system in which to examine speciation and niche evolution. We generated a fossil-calibrated phylogeny of Virentes using RADseq data to estimate divergence times and used nuclear microsatellites, chloroplast sequences and an intron region of nitrate reductase (NIA-i3) to examine genetic diversity within species, rates of gene flow among species and ancestral population size of disjunct sister species. Transitions in functional and morphological traits associated with ecological and climatic niche axes were examined across the phylogeny. We found the Virentes to be monophyletic with three subclades, including a southwest clade, a southeastern US clade and a Central American/Cuban clade. Despite high leaf morphological variation within species and transpecific chloroplast haplotypes, RADseq and nuclear SSR data showed genetic coherence of species. We estimated a crown date for Virentes of 11 Ma and implicated the formation of the Sea of Cortés in a speciation event ~5 Ma. Tree height at maturity, associated with fire tolerance, differs among the sympatric species, while freezing tolerance appears to have diverged repeatedly across the tropical–temperate divide. Sympatric species thus show evidence of ecological niche differentiation but share climatic niches, while allopatric and parapatric species conserve ecological niches, but diverge in climatic niches. The mode of speciation and/or degree of co-occurrence may thus influence which niche axis plants diverge along.
Data from: Genomic analysis reveals depression due to both individual and maternal inbreeding in a free-living mammal population
There is ample evidence for inbreeding depression manifested as a reduction in fitness or fitness-related traits in the focal individual. In many organisms, fitness is not only affected by genes carried by the individual, but also by genes carried by their parents, for example if receiving parental care. While maternal effects have been described in many systems, the extent to which inbreeding affects fitness directly through the focal individual, or indirectly through the inbreeding coefficients of its parents, has rarely been examined jointly. The Soay sheep study population is an excellent system in which to test for both effects, as lambs receive extended maternal care. Here, we tested for both maternal and individual inbreeding depression in three fitness-related traits (birthweight and weight and hindleg length at 4 months of age) and three fitness components (first-year survival, adult annual survival and annual breeding success), using either pedigree-derived inbreeding or genomic estimators calculated using ~37 000 SNP markers. We found evidence for inbreeding depression in 4-month hindleg and weight, first-year survival in males, and annual survival and breeding success in adults. Maternal inbreeding was found to depress both birthweight and 4-month weight. We detected more instances of significant inbreeding depression using genomic estimators than the pedigree, which is partly explained through the increased sample sizes available. In conclusion, our results highlight that cross-generational inbreeding effects warrant further exploration in species with parental care and that modern genomic tools can be used successfully instead of, or alongside, pedigrees in natural populations.
Data from: Regulation of thermal acclimation varies between generations of the short-lived mosquitofish (Gambusia holbrooki) that developed in different environmental conditions
1. Environmental variability and perturbations can influence population persistence. It is therefore important to understand whether and how animals can compensate for environmental variability, and thereby increase resilience of natural populations. Evolutionary theory predicts that in fluctuating environments selection should favour developmental modifiers that reduce phenotypic expression of genetic variation. The expected result is that phenotypes are buffered from environmental variation across generations. 2. Our aim was to determine whether phenotypes of mosquitofish (Gambusia holbrooki) remain stable across generations in which individuals were born into different thermal environments. We predicted that the spring generation (cool environment) would acclimate by increasing the concentration of regulatory transcription factor mRNA and activities of rate-limiting enzymes (hierarchical regulation) to compensate for the negative thermodynamic effects of lower temperatures on metabolic and locomotor performance. In contrast, the summer-born generation (warm environment) would show less capacity for acclimation and hierarchical regulation. 4. We show that fish from both generations acclimated, but that there were significant differences in the phenotypic consequences of acclimation. The overall result was that sprint performance, metabolic scope, and the activities of cyctochrome c oxidase and lactate dehydrogenase were buffered from environmental change, and did not differ between spring and summer fish at their natural water temperatures of 15oC and 25oC, respectively. However, there were differences between generations in sustained swimming performance and citrate synthase activity. 5. We used metabolic control analysis to show that modes of regulation of metabolic scope and locomotor performance differed between generations. Spring fish showed primarily hierarchical regulation, but regulation in summer fish relied to a lesser extent on rate-limiting enzymes and transcription factors. 6. We suggest that developmental modifiers are favoured in fluctuating environments to maximise phenotypic fitness of each generation. We show that the interaction between developmental and reversible acclimation can render physiological performance of a natural population independent from climate variation.
Data from: Long live the alien: is high genetic diversity a pivotal aspect of crested porcupine (Hystrix cristata) long-lasting and successful invasion?
Studying the evolutionary dynamics of an alien species surviving and continuing to expand after several generations can provide fundamental information on the relevant features of clearly successful invasions. Here, we tackle this task by investigating the dynamics of the genetic diversity in invasive crested porcupine (Hystrix cristata) populations, introduced to Italy about 1500 years ago, which are still growing in size, distribution range and ecological niche. Using genome-wide RAD markers, we describe the structure of the genetic diversity and the demographic dynamics of the H. cristata invasive populations and compare their genetic diversity with that of native African populations of both H. cristata and its sister species, H. africaeaustralis. First, we demonstrate that genetic diversity is lower in both the invasive Italian and the North Africa source range relative to other native populations from sub-Saharan and South Africa. Second, we find evidence of multiple introduction events in the invasive range followed by very limited gene flow. Through coalescence-based demographic reconstructions, we also show that the bottleneck at introduction was mild and did not affect the introduced genetic diversity. Finally, we reveal that the current spatial expansion at the northern boundary of the range is following a leading-edge model characterized by a general reduction of genetic diversity towards the edge of the expanding range. We conclude that the level of genome-wide diversity of H. cristata invasive populations is less important in explaining its successful invasion than species-specific life-history traits or the phylogeographic history in the native source range.
Data from: Free-living bacterial communities associated with tubeworm (Ridgeia piscesae) aggregations in contrasting diffuse flow hydrothermal vent habitats at the Main Endeavour Field, Juan de Fuca Ridge
We systematically studied free-living bacterial diversity within aggregations of the vestimentiferan tubeworm Ridgeia piscesae sampled from two contrasting flow regimes (High Flow and Low Flow) in the Endeavour Hydrothermal Vents Marine Protected Area (MPA) on the Juan de Fuca Ridge (Northeast Pacific). Eight samples of particulate detritus were recovered from paired tubeworm grabs from four vent sites. Most sequences (454 tag and Sanger methods) were affiliated to the Epsilonproteobacteria, and the sulfur-oxidizing genus Sulfurovum was dominant in all samples. Gammaproteobacteria were also detected, mainly in Low Flow sequence libraries, and were affiliated with known methanotrophs and decomposers. The cooccurrence of sulfur reducers from the Deltaproteobac- teria and the Epsilonproteobacteria suggests internal sulfur cycling within these habitats. Other phyla detected included Bacteroidetes, Actinobacteria, Chloroflexi, Firmicutes, Planctomycetes, Verrucomicrobia, and Deinococcus–Thermus. Statisti- cally significant relationships between sequence library composition and habitat type suggest a predictable pattern for High Flow and Low Flow environments. Most sequences significantly more represented in High Flow libraries were related to sulfur and hydrogen oxidizers, while mainly heterotrophic groups were more represented in Low Flow libraries. Differences in temperature, avail- able energy for metabolism, and stability between High Flow and Low Flow habitats potentially explain their distinct bacterial communities.
