Comparison of methods for evaluating the suitability of Vertisols for Gossypium hirsutum (Bt cotton) in two contrasting agro-ecological regions
(Taylor and Francis (Routledge), 2018)Cotton (Gossypium sp.) is a major crop grown under rainfed conditions in Vertisols and associated soils in semi-arid tropical (SAT) regions of Peninsular India. In recent years, cotton productivity has declined due to ... -
Mobile worlds: Choice at the intersection of demographic and environmental change
(Annual Reviews, 2018-10-17)Research on environmental change has often focused on changes in population as a significant driver of unsustainability and environmental degradation. Demographic pessimism and limited engagement with demographic realities ... -
Contrasting interannual atmospheric CO2 variabilities and their terrestrial mechanisms for two types of El Niños
(European Geosciences Union (EGU) / Copernicus Publications, 2018-07-19)El Niño has two different flavors, eastern Pacific (EP) and central Pacific (CP) El Niños, with different global teleconnections. However, their different impacts on the interannual carbon cycle variability remain unclear. ... -
Natural vs anthropogenic streams in Europe: History, ecology and implications for restoration, river-rewilding and riverine ecosystem services
(Elsevier, 2018-02-21)In Europe and North America the prevailing model of “natural” lowland streams is incised-meandering channels with silt-clay floodplains, and this is the typical template for stream restoration. Using both published and new ... -
Evaluating tephrochronology in the permafrost peatlands of Northern Sweden
(Elsevier, 2018)Tephrochronology is an increasingly important tool for the dating of sediment and peat profiles for palaeoecological, palaeoclimatic and archaeological research. However, although much work has been done on tephra in ... -
Sensitivity of peatland litter decomposition to changes in temperature and rainfall
(Elsevier, 2018-06-23)Changes to climate are projected over the next 50 years for many peatland areas. As decomposition of peat-forming vegetation is likely to be intrinsically linked to these changes in climate, a clear understanding of ... -
ENSO Drives interannual variation of forest woody growth across the tropics
(Royal Society, 2018-10-08)Meteorological extreme events such as El Niño events are expected to affect tropical forest net primary production (NPP) and woody growth, but there has been no large-scale empirical validation of this expectation. We ... -
Short-term effects of drought on tropical forest do not fully predict impacts of repeated or long-term drought: gas exchange versus growth
(Royal Society, 2018-10-08)Are short-term responses by tropical rainforest to drought (e.g. during El Niño) sufficient to predict changes over the long-term, or from repeated drought? Using the world's only long-term (16-year) drought experiment in ... -
Distribution of Salt-Marsh Foraminifera in Two South African Estuaries and the Application as Sea-Level Indicators
(Coastal Education and Research Foundation (CERF), 2017-05-01)The global mean sea level is rising as a result of climate change and is likely to affect millions of people. It is essential to understand and quantify regional relative sea-level variability to be able to predict future ... -
Late Holocene sea-level changes in eastern Québec and potential drivers (dataset)
(University of Exeter, 2018-11-13)This is the dataset used for the Barnett et al. (2018) article "Late Holocene sea-level changes in eastern Québec and potential drivers" published in the journal of Quaternary Science Reviews. -
Late Holocene sea-level changes in eastern Québec and potential drivers (article)
(Elsevier, 2018)Late Holocene sea-level changes can be reconstructed from salt-marsh sediments with decimetre-scale precision and decadal-scale resolution. These records of relative sea-level changes comprise the net sea-level ... -
Holocene evolution of Portus Pisanus, the lost harbour of Pisa
(Springer Nature, 2018-08-23)The ancient harbour of Pisa, Portus Pisanus, was one of Italy's most influential seaports for many centuries. Nonetheless, very little is known about its oldest harbour and the relationships between environmental evolution ... -
Disentangling regional and local tree diversity in the Amazon
(Wiley for Oikos Editorial Office, 2009-04-03)We analyzed the most extensive data set of tree inventory plots spread over the complete Amazon basin and Guiana shield. We aimed to separate the regional and local tree alpha‐diversity to investigate the drivers of diversity ... -
Pan-tropical prediction of forest structure from the largest trees
(Wiley, 2018-10-10)Aim: Large tropical trees form the interface between ground and airborne observations, offering a unique opportunity to capture forest properties remotely and to investigate their variations on broad scales. However, despite ... -
A very public cull – The anatomy of an online issue public
(Elsevier, 2018-10-30)Geographers and other social scientists have for some time been interested in how scientific and environmental controversies emerge and become public or collective issues. Social media are now key platforms through which ... -
Floristics and biogeography of vegetation in seasonally dry tropical regions
(Commonwealth Forestry Association, 2015-08-01)To provide an inter-continental overview of the floristics and biogeography of drought-adapted tropical vegetation formations, we compiled a dataset of inventory plots in South America (n=93), Africa (n=84), and Asia (n=92) ... -
Enhanced global primary production by biogenic aerosol via diffuse radiation fertilization
(Springer Nature, 2018-08-20)Terrestrial vegetation releases large quantities of plant volatiles into the atmosphere that can then oxidize to form secondary organic aerosol. These particles affect plant productivity through the diffuse radiation ... -
Exploring uncertainty of Amazon dieback in a perturbed parameter Earth system ensemble
(Wiley, 2017-04-27)The future of the Amazon rainforest is unknown due to uncertainties in projected climate change and the response of the forest to this change (forest resiliency). Here, we explore the effect of some uncertainties in climate ... -
Virtual learning environment engagement and learning outcomes at a ‘bricks-and-mortar’ university
(Elsevier, 2018-06-02)In this study, we analyse the relationship between engagement in a virtual learning environment (VLE) and module grades at a ‘bricks-and-mortar’ university in the United Kingdom. We measure VLE activity for students enrolled ... -
Large uncertainty in carbon uptake potential of land-based climate-change mitigation efforts
(Wiley, 2018-03-23)Most climate mitigation scenarios involve negative emissions, especially those that aim to limit global temperature increase to 2°C or less. However, the carbon uptake potential in land-based climate change mitigation ...
