Abstract

P. canaliculata (Gastropoda: Ampullariidae) is a water snail that can be found in Indonesia. P. canaliculata is of concern to the community since it can become a pest in the agricultural sector and harm the community. This study aimed to determine the daily behaviour of P. canaliculata, which is located in Lake SDGs IPB University. The observations used the scan sampling method on 10 adult snails for 24 hours with three times repetitions. The results of this study indicate that P. canaliculata has four dominant behaviours: exploration, social interaction, immobile (fixed), and immobile (loose). In addition, P. canaliculata exhibits other behaviours such as siphoning out, feeding, mating, spawning, burying, exploration, and floating. Water temperature changes also influenced active and inactive behaviours. The observed activity of P. canaliculata snails was mostly carried out in water. P. canaliculata was more active in the dark phase (18.00-06.00) with water temperatures ranging from 29 to 32°C and more inactive in the light phase with water temperatures ranging from 28 to 29°C.

Abstract

Apis dorsata Fabricius is a giant forest honey bee with a wide distribution that includes Indonesia. South Sumatra, Belitung, and West Kalimantan exhibit distinct geographic and ecological characteristics that may influence the morphometric variations of this species. This study aimed to analyze the similarities and differences across various morphometric parameters of A. dorsata colonies from these three regions. A traditional morphometric approach was conducted to measure 23 morphometric parameters. A total of 120 individuals from 12 A. dorsata colonies originating from South Sumatra, Belitung, and West Kalimantan were examined. The results indicated that 12 of the 23 parameters (52.2%) differed significantly among populations. Populations from South Sumatra generally exhibited larger structural dimensions across several head, thorax, and wing parameters, whereas the Belitung populations demonstrated higher values for proboscis length and antennal socket distance. Multivariate analysis (NMDS and ANOSIM) revealed statistically significant, albeit weak, differentiation among the populations. Overall, these findings indicate the presence of localized morphometric variations across the islands, although the degree of morphological differentiation remains relatively low.
