Introduction: Over 24 subspecies or “geographic races” of honeybees in the world appear to have diversified following isolation during the Pleistocene glaciations. Research on their differences in morphology, biogeography, behavior and genetics suggest that Turkish races belong mostly to the same lineage, but evolved in extremely different habitats. Foraging strategies, honey storage, production of young, overwintering success, swarming behavior or aggression show differences between races. Such traits might be influenced during the adaptation process by habitat-specific features like daily temperature, abundance and phenology of nectar flow, length and severity of winter, or predator pressure. Method: This study includes a survey of potentially adaptive traits that belong to different genetic components identified by STRUCTURE analysis which was based on a microsatellite marker assay. Relationship between climatic conditions and potentially adaptive traits were also explored. To overcome restrictions of limited sampling, we used ecological niche modeling to estimate distributional ranges and identify possible climatic drivers of adaptation for four subspecies and one ecotype. Results and Conclusion: Although the sample sizes were low, niche models produced ranges for each of the subspecies and ecotypes that roughly correspond to particular ecoregions in Turkey. Precipitation in the warmest or coldest quarter, precipitation and temperature seasonality, mean temperature of the wettest quarter and annual mean temperature explained ranges produced by models more than other variables. Due to our survey, a number of life history traits, morphologies and behavior could be related to certain climatic features. We discuss adaptive values of the traits belonging to different honeybee subspecies and ecotypes and suggest hypotheses to test these associations within the context of queen and colony trades.

Genetic structure – geography relations of honeybee subspecies in Turkey: a survey and a test of niche overlap
Kükrer, Mert; Turak, Ayşe; Bilgin, Cemal Can (null; 2019-08-01)
Subspecies or “geographic races” of honeybees (Apis mellifera) differ in morphology, biogeography and behavior and appear to have diversified following reproductive isolation during the Pleistocene glaciation. Habitat-specific features such as daily temperature, abundance and phenology of nectar flow, length and severity of winter, or predator pressure are expected to influence morphology, foraging strategy, honey storage, production of young, overwintering success, swarming behavior or aggression in differ...

A coupled plankton-anchovy population dynamics model assessing nonlinear controls of anchovy and gelatinous biomass in the Black Sea
OĞUZ, Temel; Salihoğlu, Barış; Fach Salihoğlu, Bettina Andrea (2008-01-01)
A coupled model of lower trophic levels and anchovy Engraulis encrasicolus ponticus population dynamics was developed to analyze the mechanisms controlling sharp anchovy and gelatinous zooplankton biomass transitions from the 1960s to the 1980s in the Black Sea. An increase in anchovy stocks from estimated low (similar to 300 kt) to moderate (similar to 700 kt) in the late 1960s was related to weakening piscivore predation pressure, slight nutrient enrichment of the basin during an early eutrophication phas...
An indicator-based evaluation of Black Sea food web dynamics during 1960-2000
Akoğlu, Ekin; Salihoğlu, Barış; SOLİDORO, Cosimo (2014-06-01)
Four Ecopath mass-balance models were implemented for evaluating the structure and function of the Black Sea ecosystem using several ecological indicators during four distinctive periods (1960s, 1980-1987,1988-1994 and 1995-2000). The results exemplify how the Black Sea ecosystem structure started to change after the 1960s as a result of a series of trophic transformations, i.e., shifts in the energy flow pathways through the food web. These transformations were initiated by anthropogenic factors, such as e...
A study on cobalt adaptation and memory retention of freshwater bacteria isolates
Çıtır, Gözde; Gözen, Ayşe Gül; Department of Biology (2010)
The mucus-dwelling bacteria previously isolated from the surface of a freshwater fish species (Alburnus alburnus from Lake Mogan, Ankara), were studied to discover their cobalt resistance. The minimum inhibitory concentrations (MIC) were determined for a total of thirty six bacterial isolates. The results of the resistance studies led us to design experiments on adaptation to cobalt and subsequent memory retention. Three selected isolates were exposed to an inhibitory cobalt concentration as a mixed culture...
