In the 2011 census of India, more than 2500 settlements have been newly inducted into the category of ‘census towns’ – the lowest size-class of urban settlements in India. This is a staggering figure in light of the observation that a comparable number constituted the total number of all urban settlements recorded since 1900. Furthermore, it has been revealed through aerial images, that a vast maj
Genetic characterisation (SSU rRNA genotyping) and Scanning Electron Microscope (SEM) imaging of individual tests were used in tandem to determine the modern species richness of the foraminiferal family Elphidiidae (Elphidium, Haynesina and related genera) across the Northeast Atlantic shelf biomes. Specimens were collected at 25 locations from the High Arctic to Iberia, and a total of 1013 indivi
This introduction to the biology of standing waters integrates the effects of abiotic constraints and biotic interactions at both the population and community level, and examines how the distribution and success of different organisms in this freshwater habitat can be explained and predicted
The PREDICTS project—Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)—has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional s
How and why do institutional architectures, and the roles of private institutions therein, differ across separate areas of climate governance? Here, institutional complexity is explained in terms of the problem-structural characteristics of an issue area and the associated demand for, and supply of, private authority. These characteristics can help explain the degree of centrality of intergovernme
The evolution of industrial-era warming across the continents and oceans provides a context for future climate change and is important for determining climate sensitivity and the processes that control regional warming. Here we use post-ad 1500 palaeoclimate records to show that sustained industrial-era warming of the tropical oceans first developed during the mid-nineteenth century and was nearly
Popular Abstract in Swedish Allt liv kräver energi. Energin kan komma från olika källor, såsom nedrytning av organiska eller oorganiska föreningar, värme eller ljus. Fysikens lagar säger oss att energi inte kan nyskapas eller förbrukas, bara omvandlas mellan olika former. På så sätt tillgodogör vi oss energin i mat när vi omvandlar kemiskt bunden energi till värme, då den förbränns i kroppens muskThe xanthophyll cycle is a mechanism for short term adaptation of plants to varying light intensities. It involves a reversible conversion of violaxanthin to zeaxanthin, via the intermediate antheraxanthin, upon high light intensities. This conversion is catalyzed by violaxanthin de-epoxidase (VDE) and the product after de-epoxidation, zeaxanthin, is involved in non-photochemical quenching of exce
The Sun and the solar magnetic activity is responsible for a variety of effects in space and on the Earth. High energy radiation and charged particles are constantly being emitted from the solar atmosphere interacting with our atmosphere and technological systems in space and on the ground. The research papers included in this thesis cover analysis of solar magnetic activity, solar indices, solar
