Where water meets rock: Ecological niches and diversity hotspots of hygropetric beetles in the Neotropics

Ecological Entomology, EarlyView.
First continental‐scale synthesis of hygropetric beetle diversity and distribution across Neotropical highlands. Climatic and topographic gradients structure regional assemblages and niche overlap. Ecological convergence suggests adaptation to similar conditions across disjunct regions.

Deep sea cold seeps are a sink for mercury and source for methylmercury

Communications Earth & Environment
The effect of seafloor cold seeps on the biogeochemical cycling of mercury (Hg) remains enigmatic. Here we demonstrate substantial enrichments of mercury and methylmercury, along with the presence of microbes capable of metabolizing mercury in sediments ...

Calcification is not the Achilles' heel of cold-water corals in an acidifying ocean. [PDF]

, 2015
Ocean acidification is thought to be a major threat to coral reefs: laboratory evidence and CO2 seep research has shown adverse effects on many coral species, although a few are resilient.

PFAS from a Discrete‐Event Terrestrial Source Migrates with Groundwater to Intertidal Seepages

Groundwater, EarlyView.
PFAS is conveyed to the coastal intertidal zone from sources across the terrestrial landscape. Discharge of PFAS into the coastal ecosystem is complicated in space and time by the ongoing bi‐directional exchange of terrestrial groundwater and ocean water driven by tidal pumping within discharge areas.

Lignin Unlocks Stealth Carbon Sinks in Cold Seeps via Microbial Enzymatic Gatekeeping

Research
Cold seep ecosystems serve as critical hubs in marine carbon cycling through methane emissions and organic matter processing. While terrestrial lignin constitutes a major fraction of persistent organic carbon in cold seep sediments, its microbial ...

Lithium isotope geochemistry of marine pore waters: Insights from cold seep fluids [PDF]

, 2010
Lithium concentration and isotope data (δ7Li) are reported for pore fluids from 18 cold seep locations together with reference fluids from shallow marine environments, a sediment-hosted hydrothermal system and two Mediterranean brine basins.

Cold comfort for change: Stream mats as biological indicators of ecosystem processes in the McMurdo Dry Valleys, Antarctica

Journal of Phycology, EarlyView.
Abstract Glacier‐fed streams (GFSs) make ideal systems for studying climate‐related changes. Some of the best‐studied GFSs are found in the McMurdo Dry Valleys (MDVs) of Antarctica, one of the Earth's coldest and driest deserts. Despite their harsh and isolated nature, MDV GFSs represent an oasis of life in a landscape visually devoid of it, with ...

Population genetic structure in Sabatieria (Nematoda) reveals intermediary gene flow and admixture between distant cold seeps from the Mediterranean Sea [PDF]

, 2017
BackgroundThere is a general lack of information on the dispersal and genetic structuring for populations of small-sized deep-water taxa, including free-living nematodes which inhabit and dominate the seafloor sediments.

Ecological succession of a Jurassic shallow-water ichthyosaur fall. [PDF]

, 2014
After the discovery of whale fall communities in modern oceans, it has been hypothesized that during the Mesozoic the carcasses of marine reptiles created similar habitats supporting long-lived and specialized animal communities.

Understanding marine biodiversity patterns and drivers: The fall of Icarus

Marine Ecology, EarlyView.
Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.
