Assessing and Modelling the Influence of Household Characteristics on Per Capita Water Consumption

Publication ID: pub.1048329076

Publication date: 26/04/2016

Keywords: Built-up Area; Duhok; Evolutionary Polynomial Regression; Household Characteristics; Income; Iraq; STEPWISE Regression; Water End-use

Sustainable urban water supply management requires, ideally, accurate evidence based estimations on per capita consumption and a good understanding of the factors influencing the consumption. The information can then be used to achieve improved water demand forecasts. Water consumption patterns in the developed countries have been extensively investigated. However, very little is known for the […]

Greening of the Earth and its drivers

Publication ID: pub.1045576258

Publication date: 25/04/2016

Keywords: Climate Change; CO2 Fertilization; Cropland and Pastures; Earth System; Ecosystem Models; Ecosystem Services; Environmental Change; Global; Greening; Land Cover Change (LCC); Leaf Area Index (LAI); Nitrogen Deposition; Phosphorus Availability; Regional Management Intensities; Vegetation

Satellite records combined with global ecosystem models show a persistent and widespread greening over 25–50% of the global vegetated area; less than 4% of the globe is browning. CO2 fertilization explains 70% of the observed greening trend.

Sexual Nature? (Re)presenting Sexuality and Science in the Museum

Publication ID: pub.1020837813

Publication date: 15/04/2016

Keywords: Animal Studies; London; Museums; Natural History; Natural History Museum; Science in Public; Sex; Sexuality; UK

The past 15 years have seen dramatic changes in social norms around sex and sexuality in the UK and worldwide. In 2011, the London Natural History Museum (NHM) contributed to these debates by opening the temporary exhibition Sexual Nature, which aimed to provide ‘a candid exploration of sex in the natural world’ whilst also drawing […]

Multiscale structure of meanders

Publication ID: pub.1014869906

Publication date: 05/04/2016

Keywords: Bends; Brazil; Global; Indonesia; Kapuas River; Mahakam River; Meanders; Multiple Loops; Purus River; Red River; Scale Space Tree; US; Valley Cuvature; Wavelets

River meander planforms can be described based on wavelet analysis, but an objective method to identify the main characteristics of a meander planform over all spatial scales is yet to be found. Here we show how a set of simple metrics representing meander shape can be retrieved from a continuous wavelet transform of a planform […]

Millennial-scale vegetation changes in the tropical Andes using ecological grouping and ordination methods

Publication ID: pub.1072665884

Publication date: 21/03/2016

Keywords: Climatic and Environmental Change; Ecological Grouping; Greenland Interstadials (GI); Heinrich Stadials (HS); Lake Level Fluctuations; Millenial-scale Climate Variability; Moisture Availability; Ordination Methods; Pleistocene-Holocene Transition; Pollen Records; Tropical Andes; Tropical Vegetation; Upper Forest Line (UFL) Migrations

Abstract. We compare eight pollen records reflecting climatic and environmental change from northern and southern sites in the tropical Andes. Our analysis focuses on the last 30 000 years, with particular emphasis on the Pleistocene to Holocene transition. We explore ecological grouping and downcore ordination results as two approaches for extracting environmental variability from pollen records. […]

The terrestrial biosphere as a net source of greenhouse gases to the atmosphere

Publication ID: pub.1033054259

Publication date: 09/03/2016

Keywords: Agriculture; Asia; Atmosphere; Carbon Dioxide; Ecosystem; Global; Global Warming; Greenhouse Effect; Human Activities; Methane; Nitrous Oxide

The net balance of terrestrial biogenic greenhouse gases produced as a result of human activities and the climatic impact of this balance are uncertain; here the net cumulative impact of the three greenhouse gases, methane, nitrous oxide and carbon dioxide, on the planetary energy budget from 2001 to 2010 is a warming of the planet.
