1. Climate warming in (sub) arctic regions is expected to increase freshwater fish overwinter survival and dispersal, potentially with strong implications for macroinvertebrate assemblage composition and ecosystem processes. Several studies worldwide have shown large effects of top predators (usually fish) on macroinvertebrates in streams. However, the influence of top predators on trophic diversity, the range of food resources exploited and trophic niche redundancy is less well studied, particularly in cold regions.

Ecological impacts of global warming and water abstraction on lakes and reservoirs due to changes in water level and related changes in salinity Jeppesen, Erik; Brucet, Sandra; Naselli-Flores, Luigi; Papastergiadou, Eva; Stefanidis, Kostas; Noges, Tiina; Noges, Peeter; Attayde, Jose Luiz; Zohary, Tamar; Coppens, Jan; Bucak, Tuba; Menezes, Rosemberg Fernandes; Sousa Freitas, Francisco Rafael; Kernan, Martin; Sondergaard, Martin; Beklioğlu, Meryem (2015-05-01) According to the Intergovernmental Panel on Climate Change report released in September 2014, unprecedented changes in temperature and precipitation patterns have been recorded globally in recent decades and further change is predicted to occur in the near future, mainly as the result of human activity. In particular, projections show that the Mediterranean climate zone will be markedly affected with significant implications for lake water levels and salinity. This may be exacerbated by increased demands fo...
Impacts of climate change on water resources on eastern mountainous region of Turkey Güventürk, Abdülkadir; Yücel, İsmail; Department of Civil Engineering (2013) Temperature and precipitation are the most important indicators of climate change. Especially for the basins fed by snow, the shifts of melting to earlier times, affects the streamflow. Increase in temperature causes to shifts of melting of snow to shift to earlier times so that hydrologic regime of the river system changes, and leads to changes in climatic conditions of the region. In this study the shifts of snow melting times are analyzed for the selected 15 streamflow stations located in Euphrates, Tigr...
Assessing the impact of climate change on Mogan and Eymir Lakes' levels in Central Turkey Yagbasan, Ozlem; Yazıcıgil, Hasan (2012-05-01) Global warming is likely to have significant effect on the hydrological cycle. Some parts of the world may see significant reductions in precipitation or major alterations in the timing of wet and dry seasons. Climate change is one of the serious pressures facing water resources and their management over the next few years and decades. As part of the southern belt of Mediterranean Europe, Turkey is highly vulnerable to anticipated climate change impacts. The changes in global climate will seriously affect i...
Prioritization and selection of climate change adaptation measures: a review of the literature Dogulu, Nilay; Kentel Erdoğan, Elçin (2015-07-03) Adaptation to climate change is key to reduce associated risks and develop climate resilient communities. Adaptation measures should be designed for both current and future impacts of climate change. Nevertheless, the inherent uncertainty in climate change and its impacts, and also the intrinsic complexity in climate change adaptation process present challenges in developing, planning, and effective implementation of appropriate adaptation strategies in many countries. Despite the improvements, it is due to...
Assessment of changes in climate indices of the mediterranean climate region of Turkey Çetinkaya , İzem; Yücel, İsmail; Department of Civil Engineering (2020-10-28) As a consequence of climate change, frequency and intensity changes in extreme weather events have occurred. One of the most vulnerable regions of the world that is affected by the climate change is the Mediterranean region. Turkey as a Mediterranean country has a great importance to investigate the changes in climate behavior. 57 stations from Mediterranean climate region of Turkey have been selected as the study area for this thesis. This study aims to assess the climate indices that carry the valua...
