Life History Strategies of Non-Indigenous Por’s Goatfish (Upeneus pori) and Confamilial Red Mullet (Mullus barbatus) in The Northeastern Mediterranean

In this study, allocation of energy and time for growth and reproduction of M. barbatus and U. pori were investigated to understand life history strategies adapted by a native and non-indigenous confamilial species based on multidisciplinary survey data collected in three successive years in the NE Mediterranean. The results indicated that the species seem to fulfill their biological activities within a short period of time when the highest productivity is reached in the area. The native fish exhibits fast growth, early maturation and short reproduction season while its counterpart spawns during two different time period (dual spawning) on the bathymetric slot (upper thermocline) that M. barbatus abandons during summer.


Zooplankton of the Black Sea and the Eastern Mediterranean Similarities and dissimilarities
Kovalev, Av; Mazzocchı, Mg; Sıokoufrangou, I.; Kıdeyş, Ahmet Erkan (2001-01-01)
A synthesis of data on abundance and biomass of zooplankton in the Eastern Mediterranean (EMED) and the Black Sea shows major differences in the composition and structure of pelagic communities in the two basins. Few Mediterranean planktonic animals have invaded in the Black Sea. The great bulk of Black Sea species is represented by coastal inhabitants that spread throughout the whole basin. This process has been called “neritization” of the Black Sea fauna. Peculiarities in zooplankton assemblages of the B...
Genetic and physiology of cold and drought resistance in Turkish red pine (Pinus brutia, Ten.) populations from southern Turkey
Kandemir, Gaye Eren; Kaya, Zeki; Önde, Sertaç; Department of Biology (2002)
The purpose of the study was to determine the pattern of genetic variation in morphological and physiological traits associated with cold and drought stress using seedling from over-exploited and natural populations of Pinus brutia Ten. (Turkish red pine) from southern Turkey. To determine the pattern of genetic variation existing in over-exploited and natural populations, seedlings from 6 populations each with 40 families were raised in Ankara forest nursery from 1998-2000. Three of the populations (Yaylaa...
Zooplankton adaptation strategies against fish predation in Turkish shallow lakes
Yazgan Tavşanoğlu, Ülkü Nihan; Beklioğlu, Meryem; Jeppesen, Erik; Department of Biology (2012)
In this study, the factors influencing zooplankton community structure in Turkish shallow lakes were elucidated with four main approaches: (i) space-for-time substitution for shallow lakes using snap-shot sampling in 31 lakes along a latitudinal gradient; (ii) in-situ mesocosm experiments in eleven lakes along a latitudinal gradient using three sets of artificial plants systems; (iii)‘Habitat Choice’ laboratory experiments mimicking a ‘shallow littoral’ zone with plants and a ‘deeper pelagic’ zone with sedi...
Genetic structure of modern and ancient swordfish populations from coasts of Turkey
Yüncü, Eren; Togan, İnci Zehra; Department of Biology (2017)
In this study, partial mitochondrial DNA (mtDNA) and 8 microsatellite loci of swordfish collected from Northern Levantine Sea and Northern Aegean Sea were analyzed. Also same mtDNA region of ancient swordfish samples unearthed from Yenikapı excavation were sequenced. Obtained sequences were evaluated comparatively with the sequences from Balearic Sea, Ligurian Sea, Ionian Sea and Southern Aegean Sea, available in databases. Analysis of the molecular variance revealed a significant differentiation between We...
Population dynamics and ecology of the invasive veined rapa whelk, Rapana venosa in the southern Black Sea
MUTLU, ERHAN; Kıdeyş, Ahmet Erkan; Şahin, Fatih; Erik, Gökhan; Aksu, Hakan; Erdem, Ercan; Karayücel, Sedat; Bat, Levent (2022-05-05)
© 2022 Elsevier LtdSpatial and temporal changes in some ecological characteristics (i.e. biomass, abundance, morphometrics, sex-composition, growth parameters and population dynamics) of the invasive veined rapa whelk (Rapana venosa) were studied off Sinop Bay, in the southern Black Sea. The whelk specimens were sampled from three depths (15 m, 25 m and 35 m) at monthly intervals between November 2005 and October 2007. Custom-made pots were deployed for the capture of R. venosa individuals. Monthly distribu...
