The Population Structure Of Mesobuthus Gibbosus (Scorpiones: Buthidae) On Koufonisi Island (Central Aegean Archipelago, Greece), Dimitris Kaltsas, Moysis Mylonas

Euscorpius

The population structure of Mesobuthus gibbosus was studied over 261 night-hours of sampling during 29 consecutive nights on Koufonisi Island (central Aegean Archipelago, Greece) using the capture-recapture method. The studied population proved to be the densest of all studied scorpion populations in chaparral or intertidal habitats of Mediterranean type ecosystems and even comparable to some populations of desert scorpion species. The negative influence of moon phase on the general activity of the species and synchronization in parturition were the main factors that caused the fluctuations in population density and therefore in the percentage of active scorpions.

Identification Of Root-Knot Nematodes (Meloidogyne Spp.) Fromgreenhouses In The Middle Black Sea Region Of Turkey, Gökhan Aydinli, Sevi̇lhan Mennan

Turkish Journal of Zoology

Root-knot nematodes are among the main important pests causing serious yield losses in greenhouses worldwide, including Turkey. Accurate identification of these pests is essential for determining appropriate control strategies. Identification of Meloidogyne species based on perineal pattern morphology alone is not viable or reliable due to overlaps and high variability among the species. Therefore, our objective was to overcome the difficulties in identifying 90 populations of root-knot nematodes collected from different greenhouses in the Middle Black Sea Region (Samsun, Tokat, Amasya, Çorum, Ordu, and Sinop provinces), using not only morphological (perineal pattern morphology) but also biochemical (esterase phenotype) and molecular …
