Cold tolerance of laboratory-reared Asian longhorned beetles
<p>Low winter temperatures in temperate climates can limit the success of non-native species. The Asian longhorned beetle, <i>Anoplophora glabripennis</i>, is an invasive wood-boring pest of hardwood trees in North America and Europe. Native<em> </em><i><em>A. gl</em>abripennis </i>populations are spread across several climate zones in China and the Korean Peninsula and are likely to encounter low temperatures in at least some of this range. Understanding the lethal limits of the overwintering life stages of <i>A. glabripennis</i> is essential for accurately modeling the risk that invasive populations pose to non-native environments. In this study, we provide the first systematic characterization of the cold tolerance strategy and lower lethal limits of <i>A. glabripennis </i>eggs, larvae, and pupae. In diapausing larvae, the most common overwintering stage in this species, we measure hemolymph glycerol and osmolality and identify the effects of prolonged low temperature exposure. In developing pupae, we identify sublethal effects caused by low temperature exposure before freezing. Eggs and larvae were the most cold-tolerant life stages; eggs were freeze-avoidant with an average supercooling point of -25.8 °C and larvae were freeze tolerant with an LT<sub>90</sub> of -25 °C. Hemolymph osmolality of freeze-tolerant larvae, on average, increased to 811 mOsm during chilling. This increase was primarily driven by a concurrent, average increase of 232 mM hemolymph glycerol. Pupae died upon exposure to freezing temperatures, but accumulate strong sublethal effects prior to freezing, indicating that they are chill susceptible. Taken together, these data will be useful to inform species distribution modeling in <i>A. glabripennis</i>.</p>
Survey data from: Can community laboratory facilities increase access and inclusivity in geoscience?
<p>Geochronology and geochemistry are critical tools in geoscience research and research training, but students and faculty at many institutions have little or no access to the specialized and expensive facilities needed for sample preparation and analysis. Here, we assess whether community laboratories, dedicated to hosting visitors, can help address these inequities by increasing access to cutting-edge methods and the resulting data. We report the first three years of outcomes from such a community laboratory, the goal of which is to improve access, equity, and diversity in geoscience by making an increasingly important analytical technique more widely available. Although the community sample preparation facility we describe here focuses on the cosmogenic nuclides <sup>10</sup>Be and <sup>26</sup>Al, the model we present is viable across the geosciences. Three years of development, assessment, and refinement demonstrate that the community laboratory model shows promise for including a greater diversity of users and applications. However, challenges to fostering a diverse community still exist; the costs of supplies, isotopic analysis, and travel to the community facility are roadblocks to diversification. Our experience suggests that supporting more community laboratory facilities could be an important and efficient way to further diversify the geosciences, both in terms of the people involved and the types of research performed.</p>

Integrating laboratory experiments and biogeographic modelling approaches to understand sensitivity to ocean warming in rare and common marine annelids
<p><span>Among ectotherms, rare species are expected to have a narrower thermal niche breadth and reduced acclimation capacity and thus be more vulnerable to global warming than their common relatives. To assess these hypotheses, we experimentally quantified the thermal sensitivity of seven common, uncommon, and rare species of temperate marine annelids of the genus <em>Ophryotrocha</em> to assess those species' vulnerability to ocean warming. We measured the upper and lower limits of physiological thermal tolerance, survival, and reproductive performance of each species along a temperature gradient (18, 24, and 30 °C). We then combined this information to produce curves of each species' fundamental thermal niche by including trait plasticity. Each thermal curve was then</span> <span>expressed as a habitat suitability index (HSI) and projected for the Mediterranean Sea and temperate Atlantic Ocean under a present day (1970-2000), mid- (2050-2059) and late- (2090-2099) 21st Century scenario for two climate change scenarios (RCP2.6 and RCP8.5). Rare and uncommon species showed a reduced upper thermal tolerance compared to common species, and the niche breadth and acclimation capacity were comparable among groups. The simulations predicted an overall increase in the HSI for all species and identified potential hotspots of HSI decline for uncommon and rare species</span> <span>along the warm boundaries of their potential distribution, though they failed to project the higher sensitivity of these species into a greater vulnerability to ocean warming. In the discussion, we provide elements and caveats on the implications of our results for conservation efforts.</span></p>
