Öğe Determined aphid-host plant relations from Eastern Black Sea regions of Turkey(Artvin Çoruh Üniversitesi, 2019) Görür, Gazi; Akyıldırım Beğen, Hayal; Özhan, ŞenolAphid-host plant relationship has fascinated scientist for a long time as they had some tight interactions. There is considerable amount of mountainous land area in Far Eastern Black Sea Region of Turkey which is almost 27% and about 165 aphid species have been determined. There has been no study conducted either to detect aphid fauna of region or aphid-host plant interaction up to last decades. Compared with determined aphid species diversity with floristic richness of region and each province, number of the aphid species recorded does not reflect real aphid composition of study area. According to proposed model related with aphid-host plant diversity around the world, both heavy rainfall and mix of higher vegetation biodiversity especially underbrush plant richness might explain unexpected lower aphid species diversity compared with higher plant diversity. Recent studies carried out clearly indicated that aphid-host plant relations should be studied in detail as these relations are become much more dynamic as a result of recent climatic changes.Öğe Effect of cow manure on growth and bioactive components of Gynura pseudochina (Asteraceae)(Artvin Çoruh Üniversitesi, 2019) Perkasa, Achmad Yozar; Sagala, Danner; Mulyana, Erik; Taufıka, Rahmi; Delyanı, Rista; SagalaThe objective of this study is to determine the effect of different amounts of cow manure on growth and leaf content of Gynura pseudochina, a medicinal plant. The experiment was arranged in a randomized block design. The first factor was the dose of cow manure with three levels (0 g polybag1 (control), 500 g polybag-1 and 1000 g of polybag-1). Each experiment was repeated as 4 times. The data were analyzed with variance analysis by SAS 9.1.3 programme, significant differences at 5% were also analyzed by Duncan's Multiple Range Test. As a result of the studies, it was observed that the fertilization treatment with different doses of cow manure did not provide a significant difference in growth after 3 weeks after planting, but the leaf width was the highest after 4 weeks. In this study, it was determined that cow feces and fertilization did not increase the content of bioactive compounds of the leaf of Gynura pseudochina and the growth of canopies and tubers. The high rate of caterpillar infestations that occurred two weeks after planting disrupted the growth of Gynura pseudochina and the production of bioactive compounds. The results of the study clearly showed that cow manure did not properly increase the growth of canopies, tubers and the content of bioactive compounds of Gynura pseudochina.Öğe New locality record of Ablepharus budaki (Squamata: Scincidae) in Turkey(Artvin Çoruh Üniversitesi, 2019) Özkan, Hatice; Bülbül, Ufuk; Koç, HalimeThe Budak’s snake-eyed skink (Ablepharus budaki) is recorded from Sütçüler District of Isparta province in Turkey. The metric and meristic characters of the specimens were found similar to the specimens of A. budaki reported in the literature. Surprisingly, the new locality in the present study coincides exactly among to the distribution areas of A. kitaibelii, A. budaki and the mixed clade specified in the literatureÖğe New locality record of Lacerta agilis (Squamata: Lacertidae) in Turkey(Artvin Çoruh Üniversitesi, 2019) Bülbül, Ufuk; Koç, Halime; Özkan, Hatice; Öztürk, İhsan; Kutrup, BilalIn this study, it was given the locality record of the sand lizard (Lacerta agilis) from Yeşilköy Village, Pazar District of Rize Province of Turkey. This new record revealed the second locality for L. agilis from the eastern Black Sea coast of Anatolia. The metric and meristic features of the adult, subadult and juvenile specimens were compared to the features of the specimens of the species, L. agilis in the literature.Öğe Artvin Kent Ormanı ve halkın beklentileri(Artvin Çoruh Üniversitesi, 2019) İnanç, SevimBu çalışma ile Artvin’de yaşayan halkın kent ormanına bakışı, kent ormanından beklentileri ve kent ormanı algısı incelenmiştir. Çalışma sonucunda 100 kişiyle yapılan anket sonuçlarına göre Artvin’de yaşayan halkın Artvin Kent Ormanı’nı öncelikli olarak piknik, temiz hava, gidilecek başka bir yerin olmaması, fiziksel ve psikolojik rahatlama ve sportif faaliyetler nedeniyle kullandığı belirlenmiştir. Ayrıca Artvin Kent Ormanı’ndaki en büyük eksiklikler ise çevre kirliliği, yolların bakımsız olması ve bilgilendirme eksikliği olarak görülmektedir. Yeme içme olanaklarının kısıtlı olması da yine kent ormanını kullanan kişiler tarafından büyük bir sorun olarak ifade edilmektedir. Kent ormanından daha fazla fayda sağlamak için ulaşım olanaklarının iyileştirilmesi, yolların bakımlarının daha iyi yapılması ve alanın tanıtımının daha iyi bir şekilde yapılması gerekmektedir.
