İKLİM DEĞİŞİKLİĞİ VE TÜRKİYE HERPETOFAUNASI: BİBLİYOMETRİK BİR DERLEME (2000–2025)

Öz

Bu çalışma, Türkiye herpetofaunasının (amfibi ve sürüngenler) iklim değişikliğiyle kesişimindeki literatürü sistematik biçimde derleyip haritalamaktadır. Web of Science Core Collection taraması (Article; 2000–2025; İngilizce) 125 kayıt vermiş; PRISMA süreciyle 61 çalışma analize alınmıştır. Dâhil edilen çalışmalar taksonomik grup, coğrafi ölçek, iklim sürücüsü, etki türü ve yöntemsel yaklaşım açısından kodlanmış; ayrıca anahtar kelime ortak-görünüm ağı (VOSviewer Online; thr = 3) ve özetler üzerinden LDA konu modellemesi (k = 10, keşifsel katman) ile incelenmiştir. Yayın sayısı 2016'dan sonra belirgin biçimde artmış, 2021–2022'de en yüksek düzeye ulaşmıştır. İncelenen çalışmalar sürüngenlerde yoğunlaşmaktadır (deniz kaplumbağaları dâhil %73,8; Reptilia %41 ve deniz kaplumbağaları %33); deniz kaplumbağaları ayrı ve güçlü bir küme oluşturmaktadır. Çalışmaların çoğu birden fazla iklim değişkenini birlikte ele almakta (çoklu/diğer, %64); tek bir birincil sürücü atanabildiğinde sıcaklık öne çıkmakta (%31), yağış ve kuraklık ise birincil sürücü olarak ender görülmektedir. Tematik olarak dağılım/habitat uygunluğu ve ekolojik niş modellemesi en yaygın hattır (%49); bunu fenoloji (%18) ve deniz kaplumbağalarında yuvalama–inkübasyon sıcaklığı–TSD/cinsiyet oranı (%16) izler. Fizyoloji, demografi ve davranış gibi süreç-odaklı başlıklar birincil odak olarak ender ya da yoktur. Üç analitik merceğin (manuel kodlama, ortak-görünüm ağı ve konu modeli) aynı tematik dengesizliğe işaret etmesi bu örüntüyü güçlü biçimde desteklemektedir. Ancak üç yöntem de aynı metin girdisinden beslendiğinden, bu yakınsama bağımsız bir doğrulama değil, tutarlılık göstergesi olarak okunmalıdır. Bu boşlukları kapatmak için mekanizma-temelli uzun dönem izleme ve deneysel çalışmalara, su rejimi sürücülerini birincil olarak ele alan araştırmalara ve Türkçe/WoS-dışı literatürü de kapsayan ulusal ölçekli sentezlere öncelik verilmelidir.

Climate Change and Turkish Herpetofauna: A Bibliometric Review (2000–2025)

Öz

This study systematically compiles and maps the literature at the intersection of Turkey's herpetofauna (amphibians and reptiles) and climate change. A search of the Web of Science Core Collection (Article; 2000–2025; English) returned 125 records, of which 61 studies were retained for analysis after PRISMA screening. The included studies were coded for taxonomic group, geographic scale, climate driver, impact type, and methodological approach; they were further examined through a keyword co-occurrence network (VOSviewer Online; threshold = 3) and an LDA topic model of the abstracts (k = 10, treated as an exploratory layer). The number of publications rose markedly after 2016 and peaked in 2021–2022. The corpus is concentrated in reptiles (73.8% including sea turtles; Reptilia 41% and sea turtles 33%), with sea turtles forming a distinct and strongly connected cluster. Most studies address several climate variables simultaneously (multiple/other, 64%); where a single primary driver can be assigned, temperature predominates (31%), whereas precipitation and drought are rarely the primary driver. Thematically, distribution/habitat suitability and ecological niche modelling is the most common line of work (49%), followed by phenology (18%) and, in sea turtles, the nesting–incubation temperature–TSD/sex-ratio axis (16%). Process-oriented topics such as physiology, demography, and behaviour are rare as a primary focus, if present at all. The convergence of three analytical lenses (manual coding, the co-occurrence network, and the topic model) on the same thematic imbalance strongly supports this pattern; however, because all three methods draw on the same textual input, this convergence should be read as an indication of consistency rather than independent confirmation. Three areas stand out as priority gaps: mechanism-based studies supported by long-term monitoring and experimental designs, research treating water-regime drivers as the primary focus, and national-scale assessments that also incorporate Turkish/non-WoS sources.
