Data from: The effect of initial vortex asymmetric structure on tropical cyclone intensity change in response to an imposed environmental vertical wind shear
<p>Previous studies have investigated how the environmental vertical wind shear (VWS) may trigger the asymmetric structure in an initially axisymmetric tropical cyclone (TC) vortex and how TC intensity changes in response. In this study, the possible effect of the initial vortex asymmetric structure on the TC intensity change in response to an imposed environmental VWS is investigated based on idealized full-physics model simulations. Results show that the effect of the asymmetric structure in the initial TC vortex can either enhance or suppress the initial weakening of the TC in response to the imposed environmental VWS. When the initial asymmetric structure is in phase of the VWS-induced asymmetric structure, the TC weakening will be enhanced and vice versa. Our finding calls for realistic representation of initial TC asymmetric structure in numerical weather prediction models and observations to better resolve the asymmetric structure in TCs.</p>

Mating patterns influence vulnerability to the extinction vortex
<p class="THESIS">Earth's biodiversity is undergoing mass extinction due to anthropogenic compounding of environmental, demographic and genetic stresses. These different stresses can trap populations within a reinforcing feedback loop known as the extinction vortex, in which synergistic pressures build upon one another through time, driving down population viability. Sexual selection, the widespread evolutionary force arising from competition, choice and reproductive variance within animal mating patterns, could have vital consequences for population viability and the extinction vortex: 1) if sexual selection reinforces natural selection to fix 'good genes' and purge 'bad genes', then mating patterns encouraging competition and choice may help protect populations from extinction; 2) by contrast, if mating patterns create load through evolutionary or ecological conflict, then population viability could be further reduced by sexual selection. We test between these opposing theories using replicate populations of the model insect <i>Tribolium castaneum</i> exposed to over ten years of experimental evolution under monogamous versus polyandrous mating patterns. After a 95-generation history of divergence in sexual selection, we compared fitness and extinction of monogamous versus polyandrous populations through an experimental extinction vortex comprising 15 generations of cycling environmental and genetic stresses. Results showed that lineages from monogamous evolutionary backgrounds, with limited opportunities for sexual selection, showed rapid declines in fitness and complete extinction through the vortex. By contrast, fitness of populations from the history of polyandry, with stronger opportunities for sexual selection, declined slowly, with 60% of populations surviving by the study end. The three vortex stresses of i) nutritional deprivation, ii) thermal stress and iii) genetic bottlenecking had similar impacts on fitness declines and extinction risk, with an overall sigmoid decline in survival through time. We therefore reveal sexual selection as an important force behind lineages facing extinction threats, identifying the relevance of natural mating patterns for conservation management.</p>

Flow Measurement Dataset: Kármán Vortex Street Measured by Pressure-Sensitive Paint Technique
<p>This dataset is a pressure distribution induced by a Kármán vortex street behind a square cylinder measured by the pressure-sensitive paint (PSP) technique. This data was obtained at the small low-turbulence wind tunnel at the Institute of Fluid Science, Tohoku University. A mean velocity was set to 50 m/s. The width, length, and height of the square cylinder were 40 mm, 40 mm, and 100 mm, respectively. Then, the Reynolds number based on the width of the square cylinder was 1.1×10^5.</p>

Data from: Plasticity drives extreme cold tolerance of emerald ash borer (Agrilus planipennis) during a polar vortex
<p>Invasive species must often survive combinations of environmental conditions that differ considerably from their native range; however, for a given species it is unclear whether improved tolerance is the result of phenotypic plasticity or genetic adaptation (or both).</p> <p><em>Agrilus planipennis</em> (Coleoptera: Buprestidae; the emerald ash borer) is an invasive pest of <em>Fraxinus</em> trees in North America and Europe. Previous studies in southwestern Ontario, Canada, showed that <em>A. planipennis</em> is freeze avoidant, preventing internal ice formation by accumulating molar concentrations of glycerol in its hemolymph and depressing its supercooling point (SCP, the temperature at which it freezes). The cold tolerance of these southwestern Ontario animals was used to predict potential distribution, revealing that some Canadian cities should be too cold to allow populations to persist. However, a small population of <em>A. planipennis</em> has persisted in Winnipeg, Manitoba, Canada, through several severe 'polar vortex' events.</p> <p>In 2018/19, we collected <em>A. planipennis</em> larvae and prepupae from Winnipeg, Manitoba and Southern Ontario, and found that individuals from Winnipeg were extremely cold tolerant – with SCPs as low as -52 °C in prepupae (compared to 32 °C in Southern Ontario), and survival of unfrozen individuals exposed to -50 °C for one hour. This cold tolerance was accompanied by higher hemolymph osmolality and glycerol concentration than in the SW Ontario individuals. To distinguish between phenotypic plasticity and local adaptation, in 2020/21 we overwintered Winnipeg-sourced individuals either outdoors in southwestern Ontario or in a simulated Winnipeg winter. Simulated Winnipeg winter individuals had cold tolerance similar to those overwintered in Winnipeg, while southwestern Ontario overwintered individuals had cold tolerance similar to those collected previously in the region. The simulated winter individuals had higher hemolymph glycerol concentrations than southwestern Ontario overwintered animals, at least in part due to greater dehydration. Thus, <em>A. planipennis</em> are cold-tolerant enough to survive some of the harshest winters where their host trees can grow, and most likely attain this cold tolerance via phenotypic plasticity. These findings raise the importance of delineating sensitivity of conclusions to unexpected phenotypic plasticity when predicting potential distributions of new invasives or responses to climate change.</p> <p>The data in this dataset are the SCPs and treatment data for the experimental animals used in these cold tolerance experiments. </p>
