COASTAL VULNERABILITY ASSESSMENT FOR MERSIN AND İSKENDERUN BAYS, NORTHEASTERN MEDITERRANEAN
Aykut, Fahri; Tezcan, Devrim; Department of Oceanography (2021-2)
Coasts are sensitive and dynamic areas against natural influences such as waves, winds, currents, and tides. Pressure of human activities also accelerate the change of coasts. Climate change and global sea level rise are o...

The response of Tufted Ghost Crab, Ocypode cursor, populations to recreational activities in an urbanized coast with small-scale protected zones
Bal, Melisa; Cagri Yapan, Batuhan; Özkan, Korhan (2021-01-01)
Tufted Ghost Crabs (Ocypode cursor) experience local population declines and also range contractions at larger spatial scales due to increasing anthropogenic pressures on coastal ecosystems. Therefore, the environmental dr...
Spatial variation of larval ascaridoid nematode (Nematoda: Chromadorea: Ascaridoidea) infections in the Black Sea anchovy (Engraulis encrasicolus)
Akkuş, Gizem; Gücü, Ali Cemal (2021-01-01)
This study evaluates the Black Sea anchovy population infected by parasitic Ascaridoid Nematode larva in the Southern Black Sea. It assesses the larva's effect on fish body condition, energy stored in the body, and anchovy...
Seasonal and long-term trends in the spatial heterogeneity of lake phytoplankton communities over two decades of restoration and climate change

Mitochondrial and nuclear dna phylogeographies for two botryllid ascidian species from the north-eastern mediterranean sea
Öztürk, Esra; Karahan, Arzu; Department of Marine Biology and Fisheries (2020-10-22)
With approximately 3000 species, ascidians are the largest tunicate group in the world seas. Botrylloides belongs to the genera of the worldwide spread Botryllid ascidians. In the Eastern Mediterranean coasts, a total of s...
