The conservation of Earth's forest ecosystems is one of the great environmental challenges facing humanity in the 21st century. All of Earth's ecosystems now face the spectre of the accelerated greenhouse effect and rates of change in climatic regimes that have hitherto been unknown. In addition, multiple use forestry – where forests are managed to provide for both a supply of wood and the conservation of biodiversity – can change the floristic composition and vegetation structure of forests with significant implications for wildlife habitat. Wildlife, fire and future climate: a forest ecosystem analysis explores these themes through a landscape-wide study of refugia and future climate in the tall, wet forests of the Central Highlands of Victoria. It represents a model case study for the kind of integrated investigation needed throughout the world in order to deal with the potential response of terrestrial ecological systems to global change. The analyses presented in this book represent one of the few ecosystem studies ever undertaken that has attempted such a complex synthesis of fire, wildlife, vegetation, and climate. Wildlife, fire and future climate: a forest ecosystem analysis is written by an experienced team of leading world experts in fire ecology, modelling, terrain and climate analysis, vegetation and wildlife habitat. Their collaboration on this book represents a unique and exemplary, multi-disciplinary venture.

Abstract This study aims to investigate the spatio-temporal variability and trends in climate and its implications for rainfed agriculture in the Rib watershed, north-western highland Ethiopia from 1986 to 2050. The daily rainfall and temperature records for the period 1986–2017 were used to detect the variability and trends of the current climate using the coefficient of variation, precipitation concentration index, Mann–Kendall test, and Sen's slope estimator. On the other hand, future climate changes (2018–2050) were analyzed based on the Coupled Model Intercomparison Project version 5 (CMIP5) model outputs under under two representative concentration pathway (RCP) scenarios, RCP 4.5 and 8.5. The results showed high inter-seasonal and inter-annual variability of rainfall and temperature in the studied watershed over the last four decades. The annual and Kiremt (June–September) rainfall showed a generally increasing trend, while the Belg (March–May) rainfall exhibited a decreasing trend between 1986 and 2017. Conversely, the minimum, maximum and mean temperature demonstrated increasing trends over the study period although most of the detected trends were statistically insignificant at 5 and 10% level of significance. Future climate analysis results showed an increase in future temperature and annual and Kiremt rainfall while Belg rainfall declined.

Summary1. Caseinolytic and fibrinolytic systems for assay of plasmin in fibrinolytic agents are described which are based upon the determinations of AE/min during the linear portion of the casein-plasmin and fibrin-plasmin reaction curves respectively. A " caseinolytic-rate " unit and “fibrinolytic-rate " unit of ÄE/min × 103 during the linear portion of the respective curves are proposed.2. Data are presented indicating that a reliably linear relationship exists between plasmin concentration and these caseinolytic - and fibrinolytic-rate units.3. Data comparing results obtained with the proposed assay techniques and previously-used casein and fibrinolytic techniques are presented.4. Formulae by which caseinolytic-rate and fibrinolytic-rate units can be roughly converted into Remmert-Cohen type plasmin units are offered.5. The theoretical and practical problems which have influenced development of assays for fibrinolytic components are discussed.6. The advantages of the plasmin “rate unit” techniques vis a vis existing assays are delineated.7. The potential application of the techniques to measurements other than the plasmin content of fibrinolytic agents is discussed.
