Abstract

Self-assemblage is a form of social behavior observed in some earthworm species, where individuals spontaneously group with conspecifics. This behavior has been previously documented in Eisenia fetida, an epigeic species widely used in vermiculture. However, the presence of similar behavior in E. eugeniae, another commonly used vermicomposting species, remains untested. This study aimed to investigate the self-assemblage behavior of E. eugeniae through a Y-tube choice test, evaluating individual preferences for conspecific presence. The experiment was conducted under controlled laboratory conditions using 30 replicates for both main (with conspecifics) and control (without conspecifics) treatments. Results showed a significant preference for the conspecific group in the main test (χ² = 6.5, p = 0.01), while no directional bias was observed in the control. However, decision-making time did not differ significantly between treatments (p = 0.63). These findings indicate that E. eugeniae displays active self-assemblage behavior. Further research is needed to identify the mechanisms underlying this behavior and its implications for applied soil ecology.

Abstract

Macrobrachium lanchesteri merupakan udang air tawar yang menyebar luas di perairan Indonesia dan berpotensi mengganggu ekosistem lokal. Penelitian ini bertujuan mengkaji aspek ekologi M. lanchesteri di Danau Telaga Inspirasi, Kampus IPB Dramaga. Pengambilan sampel dilakukan pada delapan titik menggunakan perangkap berumpan usus ayam selama 48 jam, disertai pengukuran kualitas air (pH, suhu, DO). Hasil menunjukkan kelimpahan individu tertinggi pada titik dengan substrat berlumpur dan vegetasi tepi, khususnya titik 1 dan 4. Suhu dan pH perairan berkisar antara 29,2–30,8 °C dan 6,5–6,8, sedangkan DO berada pada 5,6–6,3 mg/L. Kondisi optimum bagi kelimpahan udang teridentifikasi pada suhu 29–29,5 °C, pH netral (6,5–6,6), dan DO >6 mg/L. Penurunan drastis kelimpahan pada pengulangan kedua diindikasikan akibat kualitas umpan yang menurun. Temuan ini mengonfirmasi preferensi habitat M. lanchesteri pada area bervegetasi dan menunjukkan potensi invasi serta dominansi ekologis yang perlu dimonitor secara berkelanjutan
