Multi-Season Integrated Field Documentation of a Large Felid in the Western Tien Shan: Chronological Evidence from Oqtosh and Pskem River Basin (June 2025 – February 2026)

Abstract This preliminary field report presents a multi-modal dataset documenting repeated observations of a large unidentified felid in the Western Tien Shan region (Oqtosh–Soyliq and Pskem sectors) between 2025 and 2026. The dataset includes high-zoom visual recordings (Samsung S24 Ultra), acoustic material, and metric track measurements (notably 13 × 11 cm and 11 × 8 cm impressions recorded under documented substrate conditions). Behavioral observations include resting posture, tactical repositioning following visual detection, tail curvature, and periodic eye closure while maintaining auditory vigilance. The material does not permit definitive taxonomic identification at this stage. Historical sources (e.g., Baburnama, 1530) and classical zoogeographical literature (Heptner, 1972) are referenced solely for regional context. The present report emphasizes primary field documentation and encourages independent verification through systematic camera-trap deployment, genetic sampling, and spectrographic acoustic analysis. All materials are archived with DOI registration to ensure transparency and reproducibility. Annotatsiya Ushbu dastlabki dala hisoboti 2025 va 2026-yillar oralig‘ida G‘arbiy Tyan-Shan mintaqasida (Oqtosh–Soyliq va Pskem sektorlari) yirik noma’lum mushuksimon (felid) ustida olib borilgan ko‘p marta kuzatuvlarning multimodal ma’lumotlar to‘plamini taqdim etadi. Ma’lumotlar to‘plami yuqori zoomli vizual yozuvlar (Samsung S24 Ultra), akustik materiallar va metrik iz o‘lchovlarini (xususan, hujjatlashtirilgan substrat sharoitida qayd etilgan 13 × 11 sm va 11 × 8 sm o‘lchamdagi izlar) o‘z ichiga oladi. Xulq-atvor kuzatuvlariga dam olish holati, vizual aniqlangandan keyingi taktik pozitsiyani o‘zgartirish, dum egilishi va akustik hushyorlikni saqlagan holda vaqti-vaqti bilan ko‘zlarni yumish (aloqa signali) kiradi. Mavjud materiallar ushbu bosqichda yakuniy taksonomik identifikatsiyani amalga oshirishga imkon bermaydi. Tarixiy manbalar (masalan, Boburnoma, 1530) va klassik zoogeografik adabiyotlar (Geptner, 1972) faqat mintaqaviy kontekst uchun havola qilingan. Ushbu hisobot birlamchi dala hujjatlariga urg‘u beradi va tizimli fotoqopqonlar o‘rnatish, genetik namunalar olish hamda akustik spektrografik tahlillar orqali mustaqil tekshiruv o‘tkazishni rag‘batlantiradi. Barcha materiallar shaffoflik va takrorlanuvchanlikni ta'minlash uchun DOI ro‘yxatidan o‘tkazilgan holda arxivlangan.
