Aristolochia adalica (Aristolochiaceae), a New Species from Anatolia, Turkey

Aristolochia adalica Tosunoglu & Malyer sp. nova (Aristolochiaceae) is described and illustrated from southwest Anatolia, Turkey. It is morphologically close to the East Aegean endemic A. hirta; however, these species differ in some important characteristics, such as the perianth and leaf shapes and sizes, indumentum of the limb, and seed and pollen morphology. The taxonomic relationships are discussed.

Atmospheric pollen spectrum in Stone City, Mardin; the northern border of Mesopotamia/SE-Turkey

Airborne pollen distribution in Mardin city was measured volumetrically during three consecutive years, 2014–2016. Three thousand eight hundred fifty-seven pollen grains as a mean value belonging to 44 taxa were recorded annually during the study period, and pollen grains from woody plant taxa had the more substantial atmospheric contribution with 62.66% and with 23 taxa. Despite the differences between years, the highest pollen concentration was recorded in April. The main pollen producers of the pollen spectrum were Cupressaceae (27.79%), Poaceae (21.21%), Platanus (10.29%), Morus (6.19%), Olea europaea (5.01%), Quercus (4.91%), Pinus (3.84%), and Amaranthaceae (3.73%) and almost all dominant pollen types in the city atmosphere were previously stated to be allergic. The atmospheric sampling data was characterized by the high presence of woody plants in spring, as well as the high presentation of herbaceous plants in late spring to early winter. The main pollen season (MPS) and durations of dominated pollen types were analyzed and mostly found a little bit earlier or parallel with similar studies in Mediterranean basin, but found earlier than the east. Statistical analyses were performed to compare years with each other and for correlating daily pollen concentrations of dominated pollen types concurrent with the data of meteorological parameters; a number of significant correlations were found.

Aeropalynological spectrum of Hatay, Turkey, the eastern coast of the Mediterranean Sea

An aeropalynological study during the years 2014–2015 was performed in Hatay, which is a unique sociocultural and phytogeographical area located on the border of Turkey and Syria on the eastern coast of the Mediterranean. The sampling was performed by a Hirst-type volumetric sampler (Lanzoni VPPS 2000), and pollen grains of 54 taxa were identified, of which 83.21% of the annual sum belonged to woody taxa. The highest pollen concentration was recorded in February, of which a large amount came from the Cupressaceae/Taxaceae families. The diversity of the pollen reflected the vegetation of the area and plantations of the city center, but pollen grains from Euro-Siberian elements specific to Mount Amanos could not be recorded. Pollen types found at more than 3% of the annual pollen index and considered dominant pollen types were as follows: Cupressaceae/Taxaceae (50.86%), Olea europaea (12.67%), Moraceae (7.20%), Poaceae (5.99%), Quercus (5.35%), Urticaceae (3.79%) and Pinus (3.70%); almost all dominant pollen types in the city atmosphere were previously stated to be allergic. The main pollen season starting dates of common pollen types found were one or two weeks earlier than those of the surroundings. Many statistically significant correlations were found between daily pollen concentrations and daily meteorological parameters, e.g., Cupressaceae/Taxaceae Poaceae and Urticaceae pollen correlated negatively with mean temperature in both years, and in the hindermost two families daily pollen amounts significantly correlated with wind speed in the second year. Daily Olea europaea pollen concentration showed a significant negative correlation with the amount of total daily rainfall in the second year.
