1. Thermal adaptation along a latitudinal gradient in damselflies
Sammanfattning : Understanding how temperature affects biological systems is a central question in ecology and evolutionary biology. Anthropogenic climate change adds urgency to this topic, as the demise or success of species under climate change is expected to depend on how temperature affects important aspects of organismal performance, such as growth, development, survival and reproduction.

2. Avian thermoregulation across age and seasons
Sammanfattning : Animals constantly need to relate to prevailing environmental conditions and regulate their body temperature accordingly. Body temperature regulation in birds and mammals is inherently linked to energy expenditure and, thus, thermoregulation is a physiological mechanism that could trade-off with other costly processes, with potential long-term fitness consequences.

3. Winter behaviour of stream salmonids: effects of temperature, light, and ice cover
Sammanfattning : In boreal streams, stream salmonids typically face low water temperatures and variable ice conditions during winter, and thus stream salmonids are expected to use different behavioural strategies to cope with these environmental conditions. The studies presented in this thesis explore how temperature, light intensity, and surface ice affect salmonid behaviour, with focus on drift-feeding and ventilation rates. LÄS MER
4. Fair Enough? : Ecologically Unequal Exchange, International Trade, and Environmental Justice
Sammanfattning : The theory of ecologically unequal exchange (EUE) posits that contemporary international trade facilitates a net flow of resources from the peripheral global South to feed industrial processes and capital accumulation in the core North. This situation, it is argued, imperils the development of the South. LÄS MER
5. Crossing the river by feeling the stones : Approaches to Sustainable Urban Development in China
Sammanfattning : China already has the highest numbe of,and largest cities in its history. According to recent statistics, Chinese cities were home to 52.6% of China’s total population at the end of 2012. LÄS MER
