Humanity faces a major global challenge in achieving wellbeing for all, while simultaneously ensuring that the biophysical processes and ecosystem services underpin are exploited within scientifically informed boundaries of sustainability. We propose framework defining safe just operating space humanity integrates social into original planetary concept (Rockström et al., 2009a,b) application at regional scales. argue such can: (1) increase policy impact as most governance takes place rather...
A comprehensive database of paleoclimate records is needed to place recent warming into the longer-term context natural climate variability. We present a global compilation quality-controlled, published, temperature-sensitive proxy extending back 12,000 years through Holocene. Data were compiled from 679 sites where time series cover at least 4000 years, are resolved sub-millennial scale (median spacing 400 or finer) and have one age control point every 3000 with cut-off values slackened in...
Plant macrofossil data have been used to identify the successive mire communities occupying both central and marginal locations in Walton Moss peatland complex, during last 10 500 years. The reconstructed pathways of development indicate that early-Holocene fen fen-carr were succeeded by species indicative deep water tables oligotrophic conditions. character fen/bog transition (FBT) is compared with similar records from Britain Scandinavia independent climate for early Holocene....
In China, and elsewhere, long-term economic development poverty alleviation need to be balanced against the likelihood of ecological failure. Here, we show how paleoenvironmental records can provide important multidecadal perspectives on ecosystem services (ES). More than 50 different proxy mapped a wide range ES categories subcategories. Lake sediments are particularly suitable for reconstructing regulating services, such as soil stability, sediment regulation, water purification, which...
Understanding social-ecological system dynamics is a major research priority for sustainable management of landscapes, ecosystems and resources. But the lack multi-decadal records represents an important gap in information that hinders development agenda. Without improved on long-term complex interactions between causal factors responses, it will be difficult to answer key questions about trends, rates change, tipping points, safe operating spaces pre-impact conditions. Where available...
Significance We combine indicators from lake sediments with archaeological records that identify an earlier and incremental arrival of humans in East Polynesia than indicated by current models. use to reconstruct a quantitative, multiproxy hydroclimate sequences Vanuatu, Samoa, the Southern Cook Islands these published data show timing human migration into coincided prolonged drought. postulate this regional drought was significant contributory factor eastward exploration subsequent...
Summary 1. Total phosphorus (TP) and chlorophyll a (Chl ) chironomid inference models ( Brodersen & Lindegaard, 1999 ; Brooks, Bennion Birks, 2001 were used in an attempt to reconstruct changes nutrients from three very different lake types. Both training sets expanded, particularly at the low end of nutrient gradient, using contemporary assemblages environmental parameters 12 British lakes, although this had little improvement on model performances. 2. Dissimilarity analyses showed that...
Summary 1. Palaeolimnology and contemporary ecology are complementary disciplines but rarely combined. By reviewing the literature using a case study, we show how linking timescales of these approaches affords powerful means understanding ecological change in shallow lakes. 2. Recently, palaeolimnology has largely been pre‐occupied with developing transfer functions which use surface sediment‐lake environment datasets to reconstruct single environmental variable. Such models ignore complex...
Summary 1. To correctly interpret chironomid faunas for palaeoenvironmental reconstruction, it is essential that we improve our understanding of the relative influence ecosystem variables, biotic as well physicochemical, on larvae. address this, analysed surface sediments from 39 shallow lakes (29 Norfolk, U.K., 10 Denmark) head capsules, and 70 taxa (including Chaoborus ) were identified. 2. The selected over large environmental gradients aquatic macrophytes, total phosphorus (TP) fish...
1. Body size is highly correlated with physiological traits, fitness, and trophic interactions. These traits are subject to change if there widespread reductions of body warming temperatures, which suggested as one the ‘universal’ ecological responses climate change. However, general patterns response temperature in insects have not yet emerged. 2. To address this knowledge gap, we paired wing length (as a proxy for size) 5331 museum specimens 14 species British Odonata historical data....
Abstract The mid to late‐Holocene climates of most Scotland have been reconstructed from seven peat bogs located across north–south and east–west geographical climatological gradients. main techniques used for palaeoclimatic reconstruction were plant macrofossil, colorimetric humification, testate amoebae analyses, which supported by a radiocarbon‐based chronology, aided markers such as tephra isochrons recent rises in pine pollen spheroidal carbonaceous particles (SCPs). Field stratigraphy...
