Global glacier volume projections under high-end climate change scenarios

Shannon, Sarah ; Smith, Robin ; Wiltshire, Andy ; Payne, Tony ; Huss, Matthias ; Betts, Richard ; Caesar, John ; Koutroulis, Aris ; Jones, Darren ; Harrison, Stephan

In: The Cryosphere, 2019, vol. 13, no. 1, p. 325–350

The Paris agreement aims to hold global warming to well below 2 ∘C and to pursue efforts to limit it to 1.5 ∘C relative to the pre-industrial period. Recent estimates based on population growth and intended carbon emissions from participant countries suggest global warming may exceed this ambitious target. Here we present glacier volume projections for the end of this century, under a...

Towards a Holarctic synthesis of peatland testate amoeba ecology : Development of a new continental-scale palaeohydrological transfer function for North America and comparison to European data

Amesbury, Matthew J ; Booth, Robert K ; Roland, Thomas P ; Bunbury, Joan ; Clifford, Michael J ; Charman, Dan J ; Elliot, Suzanne ; Finkelstein, Sarah ; Garneau, Michelle ; Hughes, Paul D.M ; Lamarre, Alexandre ; Loisel, Julie ; Mackay, Helen ; Magnan, Gabriel ; Markel, Erin R ; Mitchell, Edward A.D ; Payne, Richard J ; Pelletier, Nicolas ; Roe, Helen ; Sullivan, Maura E ; Swindles, Graeme T ; Talbot, Julie ; van Bellen, Simon ; Warner, Barry G

Fossil testate amoeba assemblages have been used to reconstruct peatland palaeohydrology for more than two decades. While transfer function training sets are typically of local-to regional-scale in extent, combining those data to cover broad ecohydrological gradients, from the regional-to continental- and hemispheric-scales, is useful to assess if ecological optima of species vary geographically...

Benthic foraminifera in a deep-sea high-energy environment: the Moira Mounds (Porcupine Seabight, SW of Ireland)

Fentimen, Robin ; Rüggeberg, Andres ; Lim, Aaron ; El Kateb, Akram ; Foubert, Anneleen ; Wheeler, Andrew J. ; Spezzaferri, Silvia

In: Swiss Journal of Geosciences, 2018, vol. 111, no. 3, p. 561–572

Cold-water coral ecosystems represent unique and exceptionally diverse environments in the deep-sea. They are well developed along the Irish margin, varying broadly in shape and size. The Moira Mounds, numerous small-sized mounds, are nestled in the Belgica Mound Province (Porcupine Seabight, North-East Atlantic). The investigation of living (Rose Bengal stained) and dead benthic...

Post-metamorphic ontogeny of Zoroaster fulgens Thomson, 1873 (Asteroidea, Forcipulatacea)

Fau, Marine ; Villier, Loïc

In: Journal of Anatomy, 2018, vol. 233, no. 5, p. 644–665

The complete ontogenetic development of an asteroid skeleton has never been described formally for any species. Here, we describe in detail the post-metamorphic ontogeny of Zoroaster fulgens Thomson, 1873. The major novelty of our work is the description of patterns of plate addition, the ontogeny of the internal ossicles, as well as the variability of ossicles according to their position...
