Northeastern Mediterranean coasts of Turkey host critically endangered Mediterranean monk seal. In this study, the vital parameters of the monk seal colony which have been obtained since 1994 were evaluated by using population viability analysis to evaluate the risk of extinction of the species in the eastern Mediterranean, and their expected chances for recovery. This study also aims to compare the effect of Marine Protected Area established in 1999 on the conservation of the species. Annual survival rate of the colony was estimated as 0.926 and annual fecundity of the colony was estimated as 0.182 pups per adults. With these parameters, risk of extinction of the colony was estimated as 0.5% for next 20 years. Besides, scenarios like “what if the MPA has not been established” and “to what extent MPA has contributed to the conservation of the species” was tested using model parameters estimated for the period before the establishment of MPA (1994-1999) and the following period (2000-2005). With pre-MPA parameter estimates (1994-1999) probability of falling below 2 individuals at least once during the next 20 years is 27.8%. Whereas after MPA the probability is reduced to 0.17% supporting significantly positive effect of the protection.

Demography and population structure of Northeastern Mediterranean monk seal population Kurt, Merve; Gücü, Ali Cemal (2021-01-01) Copyright © 2020 Mediterranean Marine ScienceThe Northeastern Mediterranean coasts that border southern Turkey host one of the last strongholds for the survival of the endangered Mediterranean monk seal (Monachus monachus, 1779). The seal colonies inhabiting south coast of Turkey have been studied since 1994 through various short-term research projects focusing on distinct small populations that were thought to be isolated. In this study, the entire extent of the area was monitored approximately for 3 years...
The Mediterranean monk seal Monachus monachus: status, biology, threats, and conservation priorities Karamanlidis, Alexandros A.; Dendrinos, Panagiotis; De Larrinoa, Pablo Fernandez; Gücü, Ali Cemal; Johnson, William M.; Kirac, Cem O.; Pires, Rosa (2016-04-01) The Mediterranean monk seal Monachus monachus is the most endangered seal species. In this review we summarize the status, ecology, and behaviour of the Mediterranean monk seal, and identify the main threats that currently affect the species and the conservation priorities for securing its survival. Once abundant throughout the Black Sea and Mediterranean, as well as off the Atlantic coasts of northwestern Africa and Macaronesia, the Mediterranean monk seal has recently suffered dramatic declines, both in a...
Recent status and fate of the north-eastern Mediterranean monk seal populations. KURT, MERVE; Ok, Meltem; Gücü, Ali Cemal (2019-12-09) The endangered Mediterranean monk seal (Monachus monachus) is represented by approximately 350-450 individuals in Eastern Mediterranean waters in the form of small, fragmented and isolated groups. The North-eastern Mediterranean coast of Turkey being the host to one of the last continuously breeding populations, has vital importance for the survival of the species. Small populations inhabiting this region have been studied extensively for the last 25 years. The recent surveys showed that fragmented populati...
Will the Mediterranean monk seal (Monachus monachus Hermann, 1779) in the Northeastern Mediterranean become extinct in the future? Ok, Meltem; Gücü, Ali Cemal (2008-03-13) The northeastern Mediterranean coast of Turkey is one of the last remaining refuges where the critically endangered Mediterranean monk seal still survives and reproduces. The monk seal colony in this area has been closely monitored since 1994. In this study, the vital parameters of the monk seal colony, obtained since 1994, were evaluated using population viability analysis to estimate the risk of further decline of this species in the northeastern Mediterranean, and their expected chances of recovery. The ...
Breeding success and reproductive behavior in a white stork (ciconia ciconia) colony in Ankara Göcek, Çağrı; Bilgin, Cemal Can; Department of Biology (2006) White Stork ( Ciconia ciconia, Linnaeus, 1758) is a summer visitor and passage migrant in Turkey. Although being widespread in summer near wetlands of Turkey, except for the eastern and western parts of the Black Sea Region, there has been no research on this species involving regular monitoring of nests. In this study, breeding success and survival of nestlings in a population in Kızılcahamam-Ankara as well as behavioral differences among nests and their probable consequences on breeding success were studi...
