Forest ecosystems have an important role in carbon cycle at both regional and global scales as an important carbon sink. Forest degradation and land cover changes, caused by deforestation and conversion to non-forest area, have a strong impact on carbon storage. The carbon storage of forest biomass and its changes over time in the Hartlap planning unit of the southeastern part of Turkey have been estimated using the biomass expansion factor method based on field measurements of forests plots with forest inventory data between 1991 and 2002. The amount of carbon storage associated with land use and land cover changes were also analyzed. The results showed that the total forested area of the Hartlap planning unit slightly increased by 2.1%, from 27,978.7 ha to 28,282.6 ha during the 11-year period, and carbon storage increased by 9.6%, from 390,367.6 to 427,826.9 tons. Carbon storage of conifer and mixed forests accounted for about 70.6% of carbon storage in 1991, and 67.8% in 2002 which increased by 14,274.6 tons. Land use change and increasing forest area have a strong influence on increasing biomass and carbon storage.

This study determined the distribution and some diagnostic characteristics of Capoeta damascina, which belongs to the Cyprinidae family, in the Ceyhan and Seyhan River basins. C. damascina individuals were detected in 21 of 25 Ceyhan River Basin stations and 12 out of 15 in the Seyhan River Basin stations. C. damascina show a wide distribution in the Ceyhan and Seyhan River basinss. It has been determined that C. damascina lives at altitudes between 125 m (Hemite Stream) and 1620 m (Söğütlü Stream) in the Ceyhan River basins, and in streams at altitudes ranging from 165 m (Çakıt stream) to 1758 m (Sarız Stream) in the Seyhan River basins. The average total length of C. damascina individuals (n: 217) caught in the Ceyhan River Basin is 14.72 cm, and their average weight is 40.12 g. In the Seyhan River Basin, the average total length of C. damascina individuals (n: 74) was found to be 17.31 cm, and their average weight was 72.24 g. The mean number of line lateral scales was 71, the number of gill rakers was 23, and the number of pharyngeal teeth was 4:3:2-2:3:4.

yillari arasindaki arazi kullanimi/arazi örtüsü değişiminde meydana gelen zamansal değişimler irdelenmiştir. Bu amaçla, orman amenajman planlari, sayisal meşcere haritalari ve ArcGIS 10.5 TM yazilim programi kullanilarak zamansal değişim haritalari oluşturulmuştur. Gerçekleştirilen bindirme (overlay) analizi yardimiyla geçiş (transition) matrisleri üretilerek değişimler ortaya konulmuştur. Araştirma alaninda otuz bir yillik periyotta toplam ormanlik alan miktarinda 57,8 (%0,7) hektar ve verimli orman alaninda 400 (%5) hektarlik bir artiş belirlenmiştir. Orman ekosistemindeki değişikliklerin izlenmesi yapilacak müdahalelerde karar vericiler açisindan son derece yararli olacaktir. Ayrica sürdürülebilir orman işletmeciliğine uygun olarak orman kaynaklarinin planlanmasi bakimindan, orman ekosistemlerinde meydana gelen zamansal değişimler ile bunlari etkileyen etmenlerin belirlenmesi önemlidir.
