Globally, temperature and precipitation patterns are predicted to change markedly as a result of climate change. Particularly, the regions with cold or hot semi-arid Mediterranean zone expected be strongly affected.1IPCCParry M.L. Canzian O.F. Palutikof J.P. van der Linden P.J. Hanson C.E.

Summary 1. Recent experimental and field studies on temperate shallow lakes indicate that nitrogen may play a greater role in their functioning than previously thought. Several document abundance richness of submerged macrophytes, both central lake ecology, decrease with increasing loading, especially at high phosphorus levels. However, the warm fluctuating water regimes remains to be described detail. 2. The effect nitrate phosphate concentrations macrophyte growth was examined 3‐month...
The Konya Closed Basin (KCB) in Turkey has a cold semiarid to warm Mediterranean climate and hosts the largest Turkish freshwater lake, Lake Beyşehir, iconic saline Tuz. Using published as well our own ground-truth remote sensing data, we provide (1) brief description of paleoenvironmental changes KCB; followed by (2) detailed land use, crop farming, groundwater surface water levels, climate; (3) associated lake area salinity waterbird fish communities during past 40 years. KCB is...
Global warming and altered precipitation patterns are predicted to intensify the water loss in semi-arid arid regions, such regions Turkey will be particularly affected. Moreover, abstraction, not least for irrigation purposes, is expected increase markedly, posing major threats balance of lakes thus their biodiversity. Among closed basins Turkey, Burdur Closed Basin (BCB), located southwest most The BCB includes several types aquatic ecosystems which support high biodiversity, including one...
A two-decade (1989–2008) time series of lake phyto- and zooplankton, water characteristics climate in 17 Danish lakes was analysed to examine the long term changes effects restoration efforts. The analyses pair-wise correlations across revealed a strong synchrony climatic variables among lakes. significant, but weak increase air temperature observed resulted corresponding surface only summer. Lake physico-chemical had weaker than variables. Synchrony stratification stronger chemistry as...
Groups of organisms often have congruent patterns diversity or community structure due to similar environmental requirements. However, ecological interactions across trophic levels may also promote congruence independent drivers through selective predation, niche partitioning, facilitation. We examined between phytoplankton and zooplankton communities using 20 years monitoring data from 17 Danish lakes, most which were subject external nutrient loading reduction after a period...
Eutrophication continues to be the most important problem preventing a favorable environmental state and detrimentally impacting ecosystem services of lakes. The current study describes results analyses 20 year monitoring data from two interconnected Anatolian lakes, Lakes Mogan Eymir, receiving sewage effluents undergoing restoration. first step restoration in both lakes was effluent diversion. Additionally, hypertrophic Lake biomanipulation conducted, involving removal benthi-planktivorous...
Summary Environmental species sorting and dispersal are seen as key factors in community assembly, but their relative importance scale dependence remain uncertain, the extent to which communities consistently assembled throughout biomes. To address these issues, we analysed bird metacommunity structure a 1200‐km 2 forested landscape (Istranca Forests) Turkish Thrace at margin of Western Palaearctic ( WP ) temperate‐forest biome. First, used spatial regressions Mantel tests assess...
Summary Climate warming in (sub)arctic regions is expected to increase freshwater fish overwinter survival and dispersal, potentially with strong implications for macroinvertebrate assemblage composition ecosystem processes. Several studies worldwide have shown large effects of top predators (usually fish) on macroinvertebrates streams. However, the influence trophic diversity, range food resources exploited niche redundancy less well studied, particularly cold regions. Using stable isotopes...
Climate warming threatens the structure and function of shallow lakes, not least those in Mediterranean climate. We used a space-for-time substitution approach to assess response trophic community structures as well richness evenness multiple levels temperature, hydrological, nutrient constraints. selected 41 lakes covering wide climatic, gradients within short distance for reducing effect biogeographical factors western Anatolian plateau Turkey.

Abstract Water level and submerged macrophytes are critical players for the functioning of shallow lake ecosystems; understanding how waterbird communities respond to changes in both can have important implications conservation management. Here, we evaluated effects water macrophyte status on wintering community size, functional group abundances, diversity (FD), assembly by using a dataset compiled over 50 years. We built generalised linear models evaluate above‐listed attributes mid‐winter...
Climate change is affecting freshwater ecosystems globally, particularly those in semi-arid and arid regions. The Central Anatolian Ecoregion (CAE) Türkiye has a climate home to numerous endemic fish species. We used species distribution modelling elucidate the of sixteen CAE predicted their potential distributions for 2041–2060 2081–2100 based on CMIP6 model. Half are experience significant loss climatically suitable areas. Anatolichthys fontinalis, Gobio gymnostethus, hettitorum,...
Summary To help improve our understanding of the nitrogen cycle in lakes, particularly context climate change, we analysed total ( TN ) and nitrate ‐N) data from six mesocosm experiments (in Denmark, U.K., China Turkey) covering different climatic regions. We assessed effects (N) phosphorus (P) loading, temperature, salinity water level on N processing. Water column loss (defined as processed lost units net amount per unit area time, or relative terms percentage pool 2 weeks) was sensitive...
Abstract Understanding how the causal feedback between phytoplankton and environmental drivers controlling chlorophyll a (Chl , as proxy of biomass)–nutrient relationships are modulated under different ecosystem conditions is major challenge in aquatic ecology. Using an empirical dynamic model (convergent cross mapping) on 20‐yr dataset 20 Danish lakes, we quantified hypothesized networks for each lake related them to system properties (e.g., mean water depth, nutrient concentrations extent...
