In our laboratory, we are actively conducting efforts to maintain and expand the culture of model Collembolan species for ecological health assessments.
The following are the model species currently being cultured and maintained.
1. Allonychiurus kimi (PNUCOL001)
1. Allonychiurus kimi (PNUCOL001)
Alternative collembolan species for assessment of soil quality (ISO 11267)
Geographic distribution and ecology: Distributed Korea, China, and Japan common in paddy fields in Korea, Euedaphic
Morphology: Elongated, body length 2 mm to 3 mm , eyeless and unpigmented (white), Sex ratio (% of females): 70,6 %
2. Yuukianura szeptyckii (PNUCOL002)
2. Yuukianura szeptyckii (PNUCOL002)
Alternative collembolan species for assessment of soil quality (ISO 11267)
Geographic distribution and ecology: Distributed Korea, China, and Japan common on a soil surface near a stream, Hemiedaphic
Morphology: Elongated, body length 1,5 mm to 1,7 mm, eyeless and pigmented (rose or orange colour), Sex ratio (% of females): 88 % at 15 °C to 30 °C
3. Tomocerus sp. (PNUCOL003)
3. Tomocerus sp. (PNUCOL003)
4. Bionychiurus tamilensis (PNUCOL004)
4. Bionychiurus tamilensis (PNUCOL004)
Bionychiurus tamilensis (Thunnisa & Sumithra, 2021)
Current Status: New record in South Korea. Full mitochondrial genome sequencing completed (Manuscript submitted).
Geographic distribution and ecology:
Distribution: Originally recorded from the Nilgiri Hills, India. Recently discovered at Mt. Seunghaksan, Busan, South Korea, expanding its known geographic range to East Asia.
Ecology: Found in humus-rich soils and grasslands. Unlike some hemiedaphic species, this species shows typical euedaphic (deep soil-dwelling) traits.
Morphology:
Body Form: Elongated body, typical of the family Onychiuridae.
Body Length: Approximately 0.96 mm to 1.21 mm.
Coloration: No pigment (White in alcohol/living state).
Visual Organs: No ocelli (eyeless).
