“…The Glossopteris flora occurs in the Southern Hemisphere Dfa-Dfb to Dfc zones and is interpreted to be deciduous. The southernmost part of Gondwana was interpreted to be a tundra ecosystem by Rees et al (2002), but modelled temperature using a dynamic ocean-atmosphere model produces conditions more favourable for forest growth (kiehl & Shields 2005;Roscher et al 2011). Ohashi et al 2009;Offermann et al 2011;Roden & Farquhar 2012), and to complement dendrochronology-based dendroclimatology studies (Wilson & Grinstead 1977;Schleser et al 1999;Poussart et al 2004;Treydte et al 2006;Hafner et al 2011;Au & Tardif 2012).…”

Abstract:The leaf longevity of trees, deciduous or evergreen, plays an important role in climate feedbacks and plant ecology. in modern forests of the high latitudes, evergreen trees dominate; however, the fossil record indicates that deciduous vegetation dominated during some previous warm intervals. We show, through an integration of palaeobotanical techniques and isotope geochemistry of trees in one of the earliest polar forests (Late Permian, c. 260 Ma, Antarctica), that the arborescent glossopterid taxa were both deciduous and evergreen, with a greater abundance of evergreen trees occurring in the studied forests. These new findings suggest the possibility that deciduousness was a plastic trait in ancient polar plants, and that deciduous plants, migrating poleward from lower latitudes, were probably better adapted to high-disturbance areas in environments that were light-limited.

“…This model is being employed to reconstruct historic climates (Grosfeld et al, 2007), to determine the younger history of the Andean uplift (Garreaud et al, 2010), to analyse the effect of mountains on the ocean circulation (Schmittner et al, 2011), and to evaluate biogeophysical feedbacks (Dekker et al, 2010). Furthermore, it enables investigations of climates very different from recent Earth conditions as shown in applications for Mars with and without ice (Stenzel et al, 2007), the Neoproterozoic snowball Earth (Micheels and Montenari, 2008), and the Permian climates (Roscher et al, 2011).

PLASIM-ENTSem v1.0: a spatio-temporal emulator of future climate change for impacts assessment

Abstract. Many applications in the evaluation of climate impacts and environmental policy require detailed spatiotemporal projections of future climate. To capture feedbacks from impacted natural or socio-economic systems requires interactive two-way coupling, but this is generally computationally infeasible with even moderately complex general circulation models (GCMs). Dimension reduction using emulation is one solution to this problem, demonstrated here with the GCM PLASIM-ENTS (Planet Simulator coupled with the efficient numerical terrestrial scheme). Our approach generates temporally evolving spatial patterns of climate variables, considering multiple modes of variability in order to capture non-linear feedbacks. The emulator provides a 188-member ensemble of decadally and spatially resolved (∼ 5 • resolution) seasonal climate data in response to an arbitrary future CO 2 concentration and non-CO 2 radiative forcing scenario. We present the PLASIM-ENTS coupled model, the construction of its emulator from an ensemble of transient future simulations, an application of the emulator methodology to produce heating and cooling degree-day projections, the validation of the simulator (with respect to empirical data) and the validation of the emulator (with respect to highcomplexity models). We also demonstrate the application to estimates of sea-level rise and associated uncertainty.

“…Climate has been suggested as the main controlling factor of biogeographic and phytogeographic distributions under this continental configuration (Ziegler, 1990;Rees et al, 2002;Sidor et al, 2005), and long-and short-term climate changes have been investigated for this interval using fossil floras, climate-sensitive rocks, and modelling (Cuneo, 1996;Fluteau et al, 2001;Rees, 2002;Rees et al, 2002;Roscher et al, 2008Roscher et al, , 2011Wopfner and Jin, 2009;Schneebeli-Hermann, 2012).…”

Keywords:Tetrapoda flora phytoprovinces plant-insect interactions climate endemism latitudinal diversity gradient A B S T R A C TThe late Palaeozoic is a pivotal period for the evolution of terrestrial ecosystems. Generalised warming and aridification trends resulted in profound floral and faunal turnover as well as increased levels of endemism. The patchiness of well-preserved, late Permian terrestrial ecosystems, however, complicates attempts to reconstruct a coherent, global scenario. In this paper, we provide a new reconstruction of the Bletterbach Biota (Southern Alps, NE Italy), which constitutes a unique, low-latitude record of Lopingian life on land. We also integrate floral, faunal (from skeletal and footprint studies), and plant-insect interaction data, as well as global climatic interpretations, to compare the composition of the 14 best-known late Permian ecosystems. The results of this ecosystem-scale analysis provide evidence for a strong correlation between the distribution of the principal clades of tetrapod herbivores (dicynodonts, pareiasaurs, captorhinids), phytoprovinces and climatic latitudinal zonation. We show that terrestrial ecosystems were structured and provincialised at high taxonomic levels by climate regions, and that latitudinal distribution is a key predictor of ecosystem compositional affinity. A latitudinal diversity gradient characterised by decreasing richness towards higher latitudes is apparent: mid-to lowlatitude ecosystems had the greatest amount of high-level taxonomic diversity, whereas those from high latitudes were dominated by small numbers of higher taxa. The high diversities of tropical ecosystems stem from their inclusion of a mixture of late-occurring holdovers from the early Permian, early members of clades that come to prominence in the Triassic, and contemporary taxa that are also represented in higher latitude assemblages. A variety of evidence suggests that the Permian tropics acted as both a cradle (an area with high origination rates) and museum (an area with low extinction rates) for biodiversity.
