Geniotrigona thoracica is a stingless bee bred in Kebun Buah Kandi. Stingless bee productivity is depending on various natural resources. Hence, the higher frequency and density of natural reources, the more honey produced. This research had been conducted in March 2021 at Kebun Buah Kandi, Sawahlunto City. The purposes of this study were to analyze the distribution of natural resources th…
Heterotrigona itama is a species of stingless bee that is mostly kept by local beekeepers, especially in the Kandi orchards of Sawahlunto City. The productivity of stingless bees in producing honey and propolis is determined by the activities of the worker bees. The more active these worker bees fly, the more honey and propolis are collected in the hive. This research was conducted in March…
Fiddler crab is a burrowing fauna that have important ecological role in the intertidal ecosystem, such as keystone biota and ecosystem engineer. The diverse characteristics and conditions of the intertidal flats are thought to cause differences in distribution and microhabitats preference of fiddler crabs species. Bengkalis Islands have different habitat characteristic and conditions of in…
Fiddelr crab is one of the fauna that inhabits the intertidal environment of Bengkalis Island, precisely in the Selat Baru Village area. Characteristics and conditions of the intertidal environment which are quite diverse have the potential to affect the shape of the burrow and the bioturbation activity. This study aims to reveal what species of fiddler crabs were found, burrows type, biotu…
