Response and resilience of karst subterranean estuary communities to precipitation impacts [PDF]

Ecology and Evolution, 2023
The impact of meteorological phenomena on ecosystem communities of karst subterranean estuaries (KSEs) remains unknown. KSEs are characterized by vertically stratified groundwater separated by a halocline and host endemic aquatic cave‐adapted fauna ...

Spatial Partitioning of Microbial Functional Potential Suggests Complex Nitrogen Cycling in a Subterranean Estuary. [PDF]

Environ Microbiol
Microbial communities in a Mediterranean subterranean estuary show spatially structured nitrogen‐cycling potential across hydrochemical zones. Microbial properties, more than environmental variables, predict NO2− and NH4+ concentrations, highlighting their key role in controlling nitrogen transformations prior to submarine groundwater discharge ...

Vertical Stratification of Sediment Microbial Communities Along Geochemical Gradients of a Subterranean Estuary Located at the Gloucester Beach of Virginia, United States [PDF]

Frontiers in Microbiology, 2019
Subterranean estuaries (STEs) have been recognized as important ecosystems for the exchange of materials between the land and sea, but the microbial players of biogeochemical processes have not been well examined.

Subterranean environments contribute to three-quarters of classified ecosystem services. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Methane- and dissolved organic carbon-fueled microbial loop supports a tropical subterranean estuary ecosystem [PDF]

Nature Communications, 2017
It remains unclear how oligotrophic habitats in subterranean estuaries sustain complex ecosystems. Here, using stable isotopic evidence from organic matter and pelagic shrimp, the authors show that a microbial loop fuelled by methane and dissolved ...

Stratified microbial communities in Australia’s only anchialine cave are taxonomically novel and drive chemotrophic energy production via coupled nitrogen-sulphur cycling [PDF]

Microbiome, 2023
Background Anchialine environments, in which oceanic water mixes with freshwater in coastal aquifers, are characterised by stratified water columns with complex physicochemical profiles.

Hydrological and Thermal Dynamics of a Supra‐Permafrost Subterranean Estuary

Water Resources Research
Subterranean estuaries (STEs), where groundwater interacts with seawater, influence surface and subsurface coastal ecology and biogeochemistry. In Arctic‐STEs overlying permafrost, groundwater flow and heat transport determine the fate of organic matter.

Seawater intrusion regulates microbial community structure and functional potential in subterranean estuaries of the Yangtze River [PDF]

Frontiers in Microbiology
Subterranean estuaries (STE) regulate coastal biogeochemistry through microbial activity. However, responses of microbial community structure and function to seawater intrusion in STE under climate change remain unclear.

Coastal rest during the COVID-19 pandemic enhances microbial community stability and metabolic potential in a subterranean estuary [PDF]

npj Biofilms and Microbiomes
This study examines a subterranean estuary seepage face in China’s Sanggou Bay by comparing environmental parameters and microbiome data before and after the COVID-19 lockdown, in order to reveal the regulatory mechanisms of coastal resting on microbial ...

Urban-Wild Interface Diversity: A Comprehensive Checklist of Herpetofauna of Guayaquil, Ecuador. [PDF]

Ecol Evol
Amphibians and reptiles in Guayaquil comprise multiple taxonomic orders and occur across conservation areas, forest remnants, and urban parks, including several endemic species and numerous taxa with type localities in the city. Although most species are globally classified as Least Concern, discrepancies between global and national threat assessments ...
