Recommender Thermometer for Measuring the Preparedness for Flood Resilience Management
A range of various thermometers and similar scales are employed in different human and resilience management activities: Distress Thermometer, Panic Thermometer, Fear Thermometer, fire danger rating, hurricane scales, earthquake scales (Richter
Magnitude Scale, Mercalli Scale), Anxiety Thermometer, Help Thermometer, Problem Thermometer, Emotion Thermometer, Depression Thermometer, the Torino scale (assessing asteroid/comet impact prediction), Excessive Heat Watch, etc. Extensive financing of the preparedness for flood resilience management with overheated full-scale resilience management might be compared to someone ill running a fever of 41°C. As the financial crisis hits and resilience management financing cools down it reminds a sick person whose body temperature is too low. The degree indicated by the Recommender Thermometer for Measuring the Preparedness for Flood Resilience Management with a scale between Tmin=34,0° and Tmax=42,0° shows either cool or overheated preparedness for flood resilience management. The formalized presentation of this research shows how
changes in the micro, meso and macro environment of resilience management and the extent to which the goals pursued by various interested parties are met cause corresponding changes in the âtemperatureâ of the preparedness for resilience
management. Global innovative aspects of the Recommender Thermometer developed by the authors of this paper are, primarily, its capacity to measure the âtemperatureâ of the preparedness for flood resilience management automatically, to
compile multiple alternative recommendations (preparedness for floods, including preparing your home for floods, taking precautions against a threat of floods, retrofitting for flood-prone areas, checking your house insurance; preparedness for bushfires, preparedness for cyclones, preparedness for severe storms, preparedness for heat waves, etc.) customised for a specific
user, to perform multiple criteria analysis of the recommendations, and to select the ten most rational ones for that user. Across the world, no other system offers these functions yet. The Recommender Thermometer was developed and fine-tuned in the course of the Android (Academic Network for Disaster Resilience to Optimise educational Development) project
Cities are hotspots for threatened species
Aim Although urbanization impacts many species, there is little information on the patterns of occurrences of threatened species in urban relative to nonâurban areas. By assessing the extent of the distribution of threatened species across all Australian cities, we aim to investigate the currently underâutilized opportunity that cities present for national biodiversity conservation. Location Australian mainland, Tasmania and offshore islands. Methods Distributions of Australia's 1643 legally protected terrestrial species (hereafter âthreatened speciesâ) were compiled. We assessed the extent to which they overlapped with 99 cities (ofâmore than 10,000 people), with all nonâurban areas, and with simulated âdummyâ cities which covered the same area and bioregion as the true cities but were nonâurban. We analysed differences between animals and plants, and examined variability within these groups using species accumulation modelling. Threatened species richness of true versus dummy cities was analysed using generalized linear mixedâeffects models. Results Australian cities support substantially more nationally threatened animal and plant species than all other nonâurban areas on a unitâarea basis. Thirty per cent of threatened species were found to occur in cities. Distribution patterns differed between plants and animals: individual threatened plant species were generally found in fewer cities than threatened animal species, yet plants were more likely to have a greater proportion of their distribution in urban areas than animals. Individual cities tended to contain unique suites of threatened species, especially threatened plants. The analysis of true versus dummy cities demonstrated that, even after accounting for factors such as net primary productivity and distance to the coast, cities still consistently supported a greater number of threatened species. Main conclusions This research highlights that Australian cities are important for the conservation of threatened species, and that the species assemblages of individual cities are relatively distinct. National conservation policy should recognize that cities play an integral role when planning for and managing threatened species
Geographical variation in the standard physiology of brushtail possums (Trichosurus): Implications for conservation translocations
Identifying spatial patterns in the variation of physiological traits that occur within and between species is a fundamental goal of comparative physiology. There has been a focus on identifying and explaining this variation at broad taxonomic scales, but more recently attention has shifted to examining patterns of intra-specific physiological variation. Here we examine geographic variation in the physiology of brushtail possums (Trichosurus), widely distributed Australian marsupials, and discuss how pertinent intra-specific variation may be to conservation physiology. We found significant geographical patterns in metabolism, body temperature, evaporative water loss and relative water economy. These patterns suggest that possums from warmer, drier habitats have more frugal energy and water use and increased capacity for heat loss at high ambient temperatures. Our results are consistent with environmental correlates for broad-scale macro-physiological studies, and most intra-generic and intra-specific studies of marsupials and other mammals. Most translocations of brushtail possums occur into Australia's arid zone, where the distribution and abundance of possums and other native mammals have declined since European settlement, leading to reintroduction programmes aiming to re-establish functional mammal communities. We suggest that the sub-species T. vulpecula hypoleucus from Western Australia would be the most physiologically appropriate for translocation to these arid habitats, having physiological traits most favourable for the extreme Ta, low and variable water availability and low productivity that characterize arid environments. Our findings demonstrate that geographically widespread populations can differ physiologically, and as a consequence some populations are more suitable for translocation to particular habitats than others. Consideration of these differences will likely improve the success and welfare outcomes of translocation, reintroduction and management programmes

Characterization and environmental studies on anaerobic digestion of municipal solid wastes: Pompano Beach plant. Final report
The purpose of this program is to evaluate and verify the technical and economical feasibiilty of the solid waste to methane fermentation process. Since anaerobic fermentation of solid waste materials has not been demonstrated on a large scale, there is a definite risk factor that the system will not perform as current research suggests. The proof of concept plant was built on an existing shredding and landfill site at Pompano Beach, Florida. Two digesters were built with a total capacity of 90 Mg/day of solid waste. Municipal solid wastes contain numerous substances of potential environmental concern. While some understanding of the composition of raw municipal waste and its leachate products is available, no information regarding characteristics of solid, liquid and gaseous outputs from anaerobic digestion exists. The areas of environmental concerns identified were: output gas quality, leachate (filter cake and filtrate) to groundwater system, wash water streams, filter cake, and filtrate. In order to characterize the effluent streams, the following sampling sites were chosen: air classified heavy fraction, air classified light fraction, digested slurry, output gas, filter cake, filtrate, wash water input, and wash water effluent. The technical approach consisted of physical, chemical, and biological characterization of all outputs at the plant. Analyses for major, minor and trace compounds of potential environmental concern were conducted. Relevant regulatory standards were recognized and searches for compounds on EPA priority pollutant list and carciongen list were conducted. The ultimate aim was to quantitatively relate contaminant potential with plant operating parameters. Some mutagenic studies were conducted. A significant part of the technical approach relates to the development of predictive criterion for pollutant migration by leaching and modeling studies
