The commercial interest in honeydew honey is increasing because of its higher therapeutic properties than most flower-based honeys. Marchalina hellenica Gennadius (Hemiptera: Marchalinidae) is one of the important scale insects to produce of honeydew honey and its honeydew in large quantities is collected by honeybees and used in pine honey in Turkey. The aim of this study was to survey and identify honeydew producing insects’ habitats that source of honeydew honey in pure fir forest in Bolu, spruce forests in Giresun (Black Sea region), oaks forest in Kırklareli (Thracian region) and cedar forest in Antalya (Mediterranean region). In accordance with these results, we found 20 honeydew producers and among of them are Cinara cedri Mimeur on Cedrus libani, Marchalina caucasica Hadzibejli on Abies nordmanniana subsp nordmanniana, and Picea orientalis; Nemolecanium abietis Borchsenius, Physokermes hellenicus Kozẚr & Gounari and Schizolachnus pineti on Abies bornmuelleriana; Lachnus roboris Linnaeus and Parthenolecanium rufulum (Cockerell) on Quercus spp. and Castanea sativa; Metcalfa pruinosa Say (Hemiptera: Flatidae) and Ricania simulans (Walker) (Hemiptera: Ricaniidae) on different host plants. All these insects produce large amount of honeydew depending on their population size. The article discusses the potential for these insects to produce honeydew honey. Keywords: Picea orientalis, Abies nordmanniana, Ricania simulans, Eulecanium sericeum Metcalfa pruinosa, Marchalina caucasica

This study aimed to estimate leaf litter decomposition rates in eastern beech (Fagus orientalis Lipsky) and sweet chestnut (Castanea sativa Mill.) mixed stands in Düzce-Akçakoca, located in the Western Black Sea Region of Turkey. The sampling areas represent four different elevations and two aspects at each elevation. Amounts of annual beech and chestnut litter fall were estimated as 5.19 Mg ha-1 and 4.61 Mg ha-1, respectively. Litter decomposition was examined over five time periods (0.25, 0.50, 1.25, 2.25, and 4.25 years) by using the litter bag method. The amount of remaining beech leaf litter mass was found to be 1.1, 1.2, 1.2, 1.4, and 1.3 times greater than the amount of chestnut leaf litter, respectively. However, estimated values for the decomposition rate-constant (k) of chestnut for all time periods were found to be approximately 1.5 times greater than those of beech leaf litter. Litter in beech stands decomposed more rapidly at higher elevations during the first year, but at lower elevations in the second year, likely due to increased temperature and precipitation for the corresponding years. Leaf litter in chestnut stands decomposed more rapidly at lower elevations in the second and fourth year, reflecting higher precipitation of those years.

A survey conducted in inshore waters along the Romanian coast of the Black Sea from 1994 to 2000, yielded 24 polychaete species belonging to 10 families as follows: Polynoidae (2), Phyllodocidae (2), Syllidae (3), Nereididae (5), Spionidae (5), Capitellidae (3), Nerillidae (1), Sabellidae (1), Serpulidae (1), and Spirorbidae (1). Polydora websteri (Hartman, 1943) is a new record for the Mediterranean and Black Sea region. P. cornuta (Bose, 1802) is first recorded in the Black Sea. Additionally, two other species, namely Harmothoe imbricata (Linnaeus, 1767) and Typosyllis hyalina (Grube, 1863), are new to the Romanian fauna. The systematic position of some species is discussed. The information on geographical distribution within the Mediterranean region of species found is also provided.

AbstractObservations on the taxonomy, distribution and host-plants of scale insects of several taxa in the Middle East are reported. A lectotype is designated for Bodenheimera rachelae (Bodenh.). Coccus capparidis (Green) is recorded for the first time from Israel and the Mediterranean region. C. arens Hodgson is a new synonym of C. capparidis. C. pseudo-magnoliarum (Kuw.) is recorded from Israel and France. The genus Paralecanopsis is regarded as a subjective synonym of Lecanopsis. Archaspis is synonymised with Quadraspidiotus and Archaspis ephedrae Bodenh. with Quadraspidiotus cecconii (Leonardi). The identity of Diaspis capparidis Bodenh. is established, the species is transferred to Rungaspis, and R. trabuti Balachowsky synonymised with it. R. macrolobis Kaussari is redescribed and a lectoype designated; it is recorded from Israel. A key is given to the three species of Rungaspis, and Sinaidiaspis is synonymised with this. Pseudococcus lindingeri Bodenh. is transferred to Planococcus, and Planococcus variabilis (Hall) synonymised with it. Trionymus internodii (Hall) is recorded for the first time from pineapple and from Israel.

AbstractBased on proxy records from western Black Sea cores, we provide a comprehensive study of climate change during the last glacial maximum and late-glacial period in the Black Sea region. For the first time we present a record of relative changes in precipitation for NW Anatolia based on variations in the terrigenous supply expressed as detrital carbonate concentration. The good correspondence between reconstructed rainfall intensity in NW Anatolia and past western Mediterranean sea surface temperatures (SSTs) implies that during the glacial period the precipitation variability was controlled, like today, by Mediterranean cyclonic disturbances. Periods of reduced precipitation correlate well with low SSTs in the Mediterranean related to Heinrich events H1 and H2. Stable oxygen isotopes and lithological and mineralogical data point to a significant modification in the dominant freshwater/sediment source concomitant to the meltwater inflow after 16.4 cal ka BP. This change implies intensification of the northern sediment source and with other records from the Mediterranean region, consistently suggests a reorganization of the atmospheric circulation pattern affecting the hydrology of the European continent. The early deglacial northward retreat of both atmospheric and oceanic polar fronts was responsible for the warming in the Mediterranean region, leading simultaneously to more humid conditions in central and northern Europe.
