Data from: Simulated winter warming negatively impacts survival of Antarctica's only endemic insect
<p>Antarctic winters are challenging for terrestrial invertebrates, and species that live there have specialized adaptations to conserve energy and protect against cold injury in the winter. However, rapidly occurring climate change in these regions will increase the unpredictability of winter conditions, and there is currently a dearth of knowledge on how the highly adapted invertebrates of Antarctica will respond to changes in winter temperatures.</p> <p>We evaluated the response of larvae of the Antarctic midge, <em>Belgica antarctica</em>, to simulated winters at three ecologically relevant mean temperature scenarios: Warm (-1 °C), Normal (-3 °C) and Cold (-5 °C). Within each scenario, larvae were placed into three distinct habitat types in which they are commonly observed (decaying organic matter, living moss, and <em>Prasiola crispa algae</em>). Following the simulated overwintering period, a range of physiological outcomes were measured, namely survival, locomotor activity, tissue damage, energy store levels and molecular stress responses.</p> <p>Survival, energy stores and locomotor activity were significantly lower following the Warm overwintering environment than at lower temperatures, but tissue damage and heat shock protein expression (a proxy for protein damage) did not significantly differ between the three temperatures. Survival was also significantly lower in larvae overwintered in <em>Prasiola crispa</em> algae, although the underlying mechanism is unclear. Heat shock proteins were expressed least in larvae overwintering in living moss, suggesting it is less stressful to overwinter in this substrate, perhaps due to a more defined structure affording less direct contact with ice.</p> <p>Our results demonstrate that a realistic 2 °C increase in winter microhabitat temperature reduces survival and causes energy deficits that have implications for subsequent development and reproduction. While our Warm winter scenario was close to the range of observed overwintering temperatures for this species, warmer winters are expected to become more common in response to climate change. Conversely, if climate change reduces the length of winter, some of the negative consequences of winter warming may be attenuated, so it will be important to consider this factor in future studies. Nonetheless, our results indicate that winter warming could negatively impact cold-adapted insects like the Antarctic midge.</p>

500-yr Projections of Thwaites Glacier, Antarctica, with MALI, including glacial isostatic adjustment: no elastic displacement
<p>This archive contains a subset of results reproducing the material presented in the manuscript "Stabilizing effect of bedrock uplift on retreat of Thwaites Glacier, Antarctica, at centennial timescales" by Cameron Book, et al. This archive only includes results for the simulations with elastic displacement in the GIA model disabled. These results are briefly discussed in the first paragraph of section 'Factors controlling feedbacks between glacier retreat and bedrock uplift'. The main results from the manuscript are in a separate archive. Questions should be directed to Matt Hoffman (mhoffman@lanl.gov).</p> <p>This archive contains the following directories:</p> <p>|-- N1_no_elastic<br> |-- N2_no_elastic<br> |-- N3_no_elastic<br> `-- N4_no_elastic</p> <p>The individual runs have the following corresponence to the manuscript, but<br> with the elastic displacement disabled:<br> N1=TYP<br> N2=BEST2<br> N3=VLV-THIN<br> N4=VLV</p> <p>Within each run directory, are the following model output files:<br> globalStats.nc: MALI global, scalar time-series<br> output_*.nc: MALI spatial output fields, separated by century</p>

Data from: Brachiopods from the Byrd Group (Cambrian Series 2, Stage 4), Central Transantarctic Mountains, East Antarctica
Brachiopods from Cambrian Series 2, Stage 4 carbonate strata of the Byrd Group in the Central Transantarctic Mountains, East Antarctica, are described for the first time. These include six lingulate, one paterinate, and one rhynchonelliform taxa, including the new lingulate brachiopod <i>Plicarmus wildi</i> gen. et sp. nov. The assemblage correlates closely to the brachiopods recently reported from the Xinji Formation (Shuiyu section) in North China, as well as brachiopods recovered from the <i>Dailyatia odyssei</i> Zone across the Arrowie Basin of South Australia. The first unambiguous example of the acrotretid brachiopod <i>Eohadrotreta zhenbaensis</i> Li and Holmer 2004 outside South China is also identified in the context of its ontogenetic stages. Well preserved specimens of the acrotheloid <i>Schizopholis yorkensis</i> (Holmer and Ushatinskaya in Gravestock et al., 2001) facilitates a new reconstruction of its musculature and visceral region. This data is synthesised into a new cladistic analysis that resolves Acrotheloidea as a well-supported monophyletic clade and supports previous notions of a morphocline in acrotheloid evolution.
