The sediments of Tam Pà Ling (TPL), northeastern Laos, have yielded the earliest evidence Homo sapiens in mainland Southeast Asia (∼86 ka; marine isotope stage (MIS) 5 b) with a number skeletal elements having been recovered from sequence attesting to two populations H. present vicinity between 77 ± 9 ka 39 ka. At there has very limited research into environmental conditions that these encountered during MIS 5–4. In this study, we results an analysis higher plant biomarkers (n-alkanes and...
Subterranean ecosystems host highly adapted aquatic invertebrate biota which play a key role in sustaining groundwater ecological functioning and hydrological dynamics. However, functional biodiversity studies environments, the main source of unfrozen freshwater on Earth, are scarce, probably due to cryptic nature systems. To address this, we investigate trophic ecology via stable isotope analysis, employing δ13C δ15N bulk tissues, amino acids. Specimens were collected from shallow calcrete...
Abstract Three samples of moonmilk from high-altitude caves in northeast Italy were analysed for their lipid biomarker content, providing the first organic geochemical investigation into relationship between cave bacterial communities and calcitic speleothems. The results demonstrate a positive association deposits input, which we propose relates to bio-mediation calcite nucleation processes. Comparison stalagmite geographically climatically related suggest that this is at least partially...
Abstract Groundwaters host vital resources playing a key role in the near future. Subterranean fauna and microbes are crucial regulating organic cycles environments characterized by low energy scarce carbon availability. However, our knowledge about functioning of groundwater ecosystems is limited, despite being increasingly exposed to anthropic impacts climate change-related processes. In this work we apply novel biochemical genetic techniques investigate ecological dynamics an Australian...
Abstract Coastal aquifers are vital water sources for humanity. Their quality and the ecosystem services they provide depend on integrity of their subterranean biota. However, current anthropogenic impacts such as climate change effects coastal population growth place enormous pressure sustainability these environments. Despite significance biota to function delivery services, stygofauna—groundwater‐dwelling aquatic animals—have until recently been largely ignored in aquifer monitoring...
Abstract A hundred-year stalagmite lipid biomarker record from Mechara, southeastern Ethiopia, is presented. The has been recovered at a 10-yr temporal resolution, marking the first time this achieved in work and providing opportunity to investigate relationship between records hydrological transport lags, vital issue interpreting palaeoenvironmental signals. Preserved plant-derived n -alkanes -alkanols show clear changes composition over time, relating known land-use area, particularly...
Abstract Groundwaters host highly adapted fauna, known as stygofauna, which play a key role in maintaining the functional integrity of subterranean ecosystems. Stygofaunal niche studies provide insights into ecological dynamics shaping delicate balance between hydrological conditions and community diversity patterns. This work aims to unravel trends calcrete stygofaunal community, with special focus on through Outlying Mean Index analysis (OMI) additional calculation Within Indexes (WitOMI),...
The Hexabathynella genus is the only of family Parabathynellidae that has supposedly a worldwide distribution. Currently, there are 23 species described from five continents. In Australia, two have been named eastern coast, however, few taxa collected Western Australia during stygofauna sampling as part research studies and legislated compliance-based Environmental Impact Assessments. One these areas includes Rottnest Island (Wadjemup), located offshore Perth in Australia. Unpublished data...
Abstract Previous studies on lipid biomarkers preserved in Chinese stalagmites have indicated that ratios of low‐molecular‐weight (LMW) to high‐molecular‐weight (HMW) n ‐alkanes, ‐alkan‐2‐ones, ‐alkanols and ‐alkanoic acids can be used as an index vegetation versus microbial organic matter input the system and, by extension, a marker climatic changes, with increases proportion LMW compounds coinciding colder periods. Here we test whether this hypothesis is equally applicable different...
Abstract Food web dynamics are vital in shaping the functional ecology of ecosystems. However, trophic is still its infancy groundwater ecosystems due to cryptic nature these environments. To unravel interactions between subterranean biota, we applied an interdisciplinary Bayesian mixing model design (multi‐factor BMM) based on integration faunal C and N bulk tissue stable isotope data (δ 13 δ 15 N) with radiocarbon (Δ 14 C), prior information from metagenomic analyses. We further compared...
