Endangered Basra Reed-Warbler (Acrocephalus Griseldis) Recorded For The First Time In Turkey (Aves: Acrocephalidae), Montague H. C. Neate-Clegg, Juan Ramírez Román, Berkan Demi̇r, Çağan Hakki Şekerci̇oğlu

Turkish Journal of Zoology

The Basra Reed-warbler (Acrocephalus griseldis) is an endangered songbird that breeds in the reed beds of southern Mesopotamia. Hydrological projects, war, and drought have greatly reduced the breeding habitat of this species, making its future uncertain. The first Basra Reed-warbler for Turkey was caught in a mist net on 22 May 2018 at the Aras River Ornithological Research Station, between the provinces of Kars and Iğdır. This represents one of only a few vagrant records in the eastern Mediterranean, and the northernmost record to date. It is likely that this bird was an overshooting spring migrant, but the existence of …

Morphological And Leaf Anatomical Variability Of Crocus Cf. Heuffelianus Herb. (Iridaceae) Populations From The Different Habitats Of The Balkan Peninsula, Irena Raca, Milica Jovanovic, Irena Ljubisavljevic, Marina Juskovic, Vladimir Randelovic

Turkish Journal of Botany

Crocus cf. heuffelianus Herb. belongs to the series Verni Mathew and presents one of the most complex and critical taxa within the whole genus Crocus L. Depending on different authors, C. cf. heuffelianus is sometimes split into different taxa (e.g., C. scepusiensis (Rehmer & Wol.) Borbás ex Kulcz., C. vittatus Schloss. & Vuk., nom. illeg.). In order to disentangle the complicated taxonomical status of this species and to determine the degree of its morphoanatomical variability in the different environmental conditions, a comparative investigation of plant morphology and leaf anatomy of seven populations from the Balkan Peninsula was carried out. Morphometric …

The Epiphytic Bryophyte Vegetation Of Kamilet Valley (Artvin, Turkey), Mevlüt Alataş, Nevzat Batan, Tülay Ezer

Turkish Journal of Botany

In this study, the vegetation of epiphytic bryophytes in the Kamilet Valley and its surroundings (Arhavi, Artvin) was investigated. The study area is located within the borders of the Eastern Black Sea Mountains and is one of the 122 important plant areas in Turkey. The investigation of epiphytic bryophyte communities was carried out in 2016 during different vegetation periods according to Braun-Blanquet?s phytosociological methodology. Phytosociological data obtained from 65 relevés were ordinated using detrended correspondence analysis (DECORANA) and classified using two-way indicator species analysis (TWINSPAN). Consequently, six epiphytic bryophyte communities new to Turkey were determined with TWINSPAN and DECORANA: Leucobryo-Tetraphidetum …

Turkish Journal of Zoology

Within its range, the Caspian green lizard, Lacerta strigata, occurs in the Elburz Mountains (northern Iran) at elevations from below sea level to approximately 2700 m a.s.l. To determine the environmental factors affecting the distribution of this lizard, we used an ensemble approach to model the distribution of the Caspian green lizard (Lacerta strigata) in Iran using four algorithms (generalized boosted model, maximum entropy, generalized linear model, random forest). Results revealed that low-elevation habitats between the Elburz Mountains and the Caspian Sea are the most suitable habitats for the species. The normalized difference vegetation index (NDVI), annual precipitation (both with …

Ecological Surveys On The Parthenogenetic Artemia Populations In The Hypersaline Lakes Of Anatolia, Turkey, Armi̇n Eskandari̇, Yasemi̇n Saygi

Turkish Journal of Zoology

The objective of this study is to provide information on the parthenogenetic Artemia populations in some hypersaline lakes of Anatolia (Tuz, Bolluk, Tersakan, and Acıgöl). Sampling studies were performed for abiotic factors and population parameters between November 2009 and October 2010. During the survey we focused on the local Artemia populations to investigate population dynamics, reproduction, brood size, and cyst and naupliar biometrics. Generally, the Artemia habitats in Anatolia were relatively shallow, and thus they were subject to major seasonal fluctuations. Dramatic declines in population size in Tuz and Acıgöl Lakes were found during this study. All Artemia populations were …
