Impacts of global climate change on terrestrial ecosystems are imperfectly constrained by ecosystem models and direct observations. Pervasive transformations occurred in response to warming associated climatic changes during the last glacial-to-interglacial transition, which was comparable magnitude projected for next century under high-emission scenarios. We reviewed 594 published paleoecological records examine compositional structural vegetation since glacial period project magnitudes...
A robust understanding of Antarctic Ice Sheet deglacial history since the Last Glacial Maximum is important in order to constrain ice sheet and glacial-isostatic adjustment models, explore forcing mechanisms responsible for retreat. Such can be derived from a broad range geological glaciological datasets recent decades have seen an upsurge such data gathering around continent Sub-Antarctic islands. Here, we report new synthesis those datasets, based on accompanying series reviews data,...
Abstract It is widely recognised that the acquisition of high‐resolution palaeoclimate records from southern mid‐latitude sites essential for establishing a coherent picture inter‐hemispheric climate change and better understanding role Antarctic dynamics in global system. New Zealand considered to be sensitive monitor because it one few sizeable landmasses Southern Hemisphere westerly circulation zone, critical transition zone between subtropical influences. has mountainous axial ranges...
Humans have altered natural patterns of fire for millennia, but the impact human-set fires is thought to been slight in wet closed-canopy forests. In South Island New Zealand, Polynesians (Māori), who arrived 700-800 calibrated years (cal y) ago, and then Europeans, settled ∼150 cal y used as a tool forest clearance, structure environmental consequences these are poorly understood. High-resolution charcoal pollen records from 16 lakes were analyzed reconstruct vegetation history last 1,000...
In olden times our islands were covered with forest growth; the only open spaces sterile places whereon nothing would grow. When Kupe and other early immigrants arrived here they lit fires at all whereat landed, so much was destroyed, also moa perished in those fires. Maori tradition related to Best (1942:2).
Aim To evaluate competing views on the origin and distribution of New Zealand flora by testing hypothesis that geographical species is unrelated to ecological traits such as habitat requirements dispersal capabilities. Location The archipelago. Methods An analysis factors correlated with endemism for alpine plants within Zealand, biota a whole. Results Woody are highly endemic; nonendemic tend be herbaceous concentrated among dispersible ferns fern allies, orchids wetland plants. These...
Soil nitrogen and phosphorus pools shift strongly along soil chronosequences worldwide, but variation in plant nutrient resorption these sequences is poorly understood. We quantified leaf litter concentrations 28 woody species the Franz Josef chronosequence, New Zealand, a strong fertility gradient temperate rain forest, to address two questions: How do vary chronosequence? And are community-level responses driven by compositional differences among fertile infertile sites, or consistent...
Abstract Aim The increased incidence of large fires around much the world in recent decades raises questions about human and non‐human drivers fire likelihood activity future. purpose this paper is to outline a conceptual framework for examining where human‐set feedbacks are likely be most pronounced temperate forests world‐wide establish test methodology evaluating using palaeoecological records.

This paper is the maritime and sub–Antarctic contribution to Scientific Committee for Antarctic Research (SCAR) Past Ice Sheet Dynamics (PAIS) community reconstruction. The overarching aim all sectors of Antarctica was reconstruct Last Glacial Maximum (LGM) ice sheet extent thickness, map subsequent deglaciation in a series 5000 year time slices. However, our review literature found surprisingly few high quality chronological constraints on changing glacier extents these timescales sector....
Anthropogenic activity is now recognised as having profoundly and permanently altered the Earth system, suggesting we have entered a human-dominated geological epoch, 'Anthropocene'. To formally define onset of Anthropocene, synchronous global signature within geological-forming materials required. Here report series precisely-dated tree-ring records from Campbell Island (Southern Ocean) that capture peak atmospheric radiocarbon (14C) resulting Northern Hemisphere-dominated thermonuclear...
