“…Niah Cave is located on an isolated limestone outcrop (Bukit Berkajang) and contains 13 species of bats and 3 species of Aerodramus spp. (cave swiftlets), with bat and bird cave fauna persisting for at least 48,000 years (Stimpson 2012(Stimpson , 2013. Gomantong caves are located on Gomantong hill on an isolated limestone outcrop on the flood plain of the Menugai River (Lundberg and McFarlane 2012).…”

The biogeochemistry of insectivorous cave guano: a case study from insular Southeast Asia

et al. 2015

Cave guano derived from insectivorous bats and birds contain unique geochemical and mineralogical signatures. We investigated the mineralogy, pH, C, N and metal abundance patterns of cave guano spatially and temporally (with depth) along a W-E transect in Malaysia and Palawan from five remote cave sites, each housing large populations of bats and Aerodramus spp.(cave swiftlets). Guano deposits were rich in phosphate and/or sulphate minerals (e.g., gypsum, bassanite) with leucophosphite, spheniscidite, and variscite present in most profiles. Metal abundances measured from modern and ancient bat guano revealed high concentrations of transition metals relative to the local environment. Highly enriched metals, however, were associated with phosphate rather than sulphate minerals. Copper and Zn were enriched in all profiles, whereas other metals were associated with specific caves consistent with known local mineral resources. For example, Sn, Pb, and Rb were particularly enriched in Batu Cave, located in the Peninsular Malaysian granitic tin belt, whereas Ni and Cr were high in regions associated with ultramafic ophiolites and Ni-laterites found on Palawan.

“…In contrast, avian subfossil remains are more robust materials for 14 C dating and have been widely used in ecological geology. For example, based on radiocarbon analyses of bone samples, the histories of the last 50 ka of penguins in the Ross Sea, Antarctica, and of cave swiftlets in north-western Borneo were reconstructed (Emslie et al, 2007;Stimpson, 2013). Fortunately, the Xisha Islands were once an important seabird habitat, and a large number of avian relics in sediment layers were recovered during our field investigations (Xu, 2015), enabling potential use of them to precisely trace the islands' history.…”

Reef islands of the Xisha Islands, South China Sea, were formed during the mid–late Holocene. However, the vertical accretion of ornithogenic sediments of the islands is not well understood owing to a lack of precise dating. Here we present an analysis of seven of the Xisha Islands, and reconstruct their accumulation history based on radiocarbon analysis of seabird subfossils. From Clam‐based age–depth models, a universal development mode of the Xisha Islands is hypothesized. The mean accumulation rate of guano sediments on the Xisha Islands in the late Holocene was 1.02 ± 0.42 mm a−1. The sum of the deposition rate of coral sands and the rate of ornithogenic accumulation is lower than or close to the current rate of sea level rise in the Xisha Islands, implying a potential threat to the islands’ safety. This study also provides robust evidence for a sequence of island development associated with seabirds.
