Good beech-mast crop is important not only for beech forest regeneration but it stimulates population abundances of granivorous animals. Abundant beech-mast crop was observed in autumn 2011 in Beskydy Mts. Mean mass of healthy beech-mast on Kněhyně Mts complex was 92 g.m−2 which represents 390 pieces (pc)/m2. That was why diet supply for granivorous forest rodents, in means of current biomass of beech-mast, was ascertained in 5 beech stands. At each locality, beech stands were chosen to represent Kněhyně Mt. beech forests and differ in age structure and the elevation. Biomass of beech-mast crop collected from the lowest elevation (5th vegetation tier) was higher (as to number of beechnuts/m2) and heavier (g/m2) compared to the highest elevation one (8th vegetation tier). The beech forests from the lower altitude may have a better condition for the beech seeds production. As the granivorous species are peeling the beechnuts, so the peeled diet supply of beech-mast was also stated. This should be considered if calculating diet consumption of particular rodent species.

The state and silvicultural demands in beech forests of northeast Serbia were studied in the economic regions of Severni Kucaj, Timok and Juzni Kucaj, and in the region of the National Park Djerdap. The detailed analysis of state forests was performed: representation of beech forests according to silvicultural form, origin, age structure, stand state and productivity Average volume in high beech forests of 218 m3 x ha?1 is for about 5% lower than the average in Serbia (207.2 m3 x ha?1), and it amounts to 87% of the optimal volume of beech forests in Serbia. Volume increment of 4.5 m3?ha?1 is approximate to the average increment of high beech forests in Serbia, and it amounts to 75% of the optimal value. The average volume of coppice beech forests of 150 m3?ha?1 is 60% of the optimal volume of beech forests in Serbia The age structure is unfavourable, because the percentage of well conserved mature stands is only about 8%. Unplanned regeneration has started on about 15% of the area. Middle-aged and maturing stands account for more than 3/4 of the total area (80%). Stand state of beech forests in this region can be assessed as close to unsatisfactory, if the criteria are conservation, origin, vitality, and also the health state Based on the above state, the concrete silvicultural demands for each silvicultural situation were determined and the silvicultural measures were proposed aiming at their rational utilisation and improvement of forest state: measures aiming at the establishment of new, quality stands and measures aiming at the improvement of the state of existing forests.

Age structure of the eastern spadefoot toad, Pelobates syriacus from the Kızılırmak Delta (Turkey) were assessed using phalangeal skeletochronology. Snout-vent length (SVL) ranged from 42.05 to 86.63 mm in males and 34.03 to 53.27 mm in females. Age of adults ranged from 2 to 8 years in males and 3 to 5 years in females. For both sexes, SVL was significantly correlated with age. Males and females of the toads reached maturity at 2 years of age.
