Abstract:

Uppsatsen gör en jämförelse av Växjö kommuns tidigare direktlevererande posthanteringsprocess och samordnad posthanteringsprocess som nu används på vissa områden på utbildningsförvaltningen i Växjö kommun. Genom att kartlägga de båda processerna har en jämförelse kunnat göras. Lokala, centrala och en extern respondent har intervjuats angående rättssäkerhet, arbetsmiljö, klimatpåverkan och kostnader. Genom att analysera data som samlades in tillsammans med teori om aspekterna kunde författarna komma fram till bland annat följande skillnader: Delvis försämrad arbetsmiljö Förbättrad rättssäkerhet

Abstract:

Modern tools, nontraditional datasets and a better understanding of the interaction between climate and ecohydrology are continuously being developed as today's society is in critical need for improving water management, predicting hydrometeorological hazards and forecasting future climate. In particular, the study of the intra- and inter-annual variations in grass productivity and evapotranspiration caused by variations in precipitation/soil moisture and other biophysical factors is of great significance due to their relation to future climatic changes. The research presented here falls in th

Abstract:

Rice (Oryza sativa) is the most important crop for human direct consumption, but its yield and production are strongly affected by biotic and abiotic stresses. Rice is the most salt-sensitive cereal and in addition, salinity is a rising problem around the world reinforced by the climate change effects such as rise of the sea level, soil degradation and water scarcity. Regarding biotic stresses, the apple snail (Pomacea sp.) is one of the worst introduced pest that affects rice production. It has been detected for first time in Europe in Spain, in 2009 in Ebro River Delta, destroying rice field

Abstract:

Throughout the Holocene, bison have always been more abundant east of the Rocky Mountains with considerably fewer bison found west of the Rocky Mountains. It is likely that drought frequency and snowfall characteristics have influenced the pattern of historical bison occurrence across the northwest United States. Using monthly average snow and precipitation data from the past several decades, average April snow water equivalent (SWE) and summertime drought frequency were analyzed at sites across the northwest United States. A climatic stress index (CSI) was developed by combining average SWE a

Abstract:

The Mediterranean Basin is a climate-change hotspot of the world. Predicted reductions in annual precipitation, increases in mean temperature, and increases in the variability and occurrence of extreme droughts and heat waves are likely to affect species abundance and distribution. The existence of sympatric plants with different morphological and phenological strategies raises the question how they will respond to novel climate conditions. There is a strong need to improve the mechanistic understanding of key foliar ecophysiological parameters in response to abiotic stressors on a small scale

Abstract:

Dimethylsulphoniopropionate (DMSP) and dimethylsulphoxide (DMSO) (collectively DMSP/O) are produced by marine algae, including symbiotic algae within corals. These sulphur compounds are important not only in sulphur cycle dynamics but also in potentially mediating atmospheric conditions, alleviating the effects of climate change and contributing to reef health. Most research has focused on the production of DMSP and its major degradation product, the climatically active gas, dimethylsulphide (DMS) by Acropora corals in the Great Barrier Reef. However, mechanisms for the production and release

Chapter 1: Antarctic fishes are extremely cold adapted. Despite their inability to upregulate heat shock proteins, recent studies have demonstrated a capacity for heat response in these animals. A cDNA microarray study looked at the Notothenioid fish Trematomus bernacchii and revealed heat sensitivities for hundreds of genes, two of which code for members of the CCAAT/Enhancer-binding protein (C/EBP) family of transcription factors. These molecular switches are best known for their roles in apoptosis, inflammation and cell cycle arrest. This dissertation further elucidates the role of C/EBP-de

Abstract:

Changes in temperature and precipitation due to climate change are expected to increase stream water temperature and reduce their discharge. Consequently, more streams might face temporality, experiencing flow intermittency or complete streambed drying. The general aim of this thesis was to determine how climate-induced changes in stream hydrology (drought) and water temperature (warming) influence resource- consumer trophic interactions. Our results showed that although highly reliant on nutrient-poor allochthonous organic matter, most consumers in a forested Mediterranean stream complemen

Abstract:

Marine and coastal ecosystems are subject to diverse and increasingly intensive anthropogenic activities, making understanding cumulative effects critically important. However, accurately accounting for the cumulative effects of human impacts can be difficult, with the possibility of multiple stressors interacting and having greater impacts than expected, compounding direct and indirect effects on individuals, populations, communities and ecosystems. Assessment of multiple stressors therefore requires extensive scientific research that directly tests how single or multiple ecological component

Abstract:

Maize (Zea mays L.) is an important crop in the world; however, its yield is compromised by new production challenges leading to poor yield in sub-Saharan Africa. This calls for a need to enhance maize adaptation to changing climate and challenging environments. The new maize varieties should be richly endowed with high frequency of genes that confer high yield under stress and non-stress conditions. Currently, such maize is not available, prompting research into development of new germplasm lines for use in developing new hybrids. The objective of the study was to determine i) the level of ge
