Crustal Mercury Addition Into the Giant Jinchuan Ni‐Cu Sulfide Deposit, China, and Its Geological Implications

open access: yesGeochemistry, Geophysics, Geosystems, 2022
Mercury (Hg) isotopes have shown their power of tracing Hg pollution sources in ecosystems, but their potentials for petrogenetic tracing are yet to be explored.

Heinrich event 4 characterized by terrestrial proxies in southwestern Europe [PDF]

open access: yesClimate of the Past, 2013
Heinrich event 4 (H4) is well documented in the North Atlantic Ocean as a cooling event that occurred between 39 and 40 Ka. Deep-sea cores around the Iberian Peninsula coastline have been analysed to characterize the H4 event, but there are no data on ...

The evolution of parental care in salamanders

open access: yesScientific Reports, 2022
Complex parenting has been proposed to contribute to the evolutionary success of vertebrates. However, the evolutionary routes to complex parenting and the role of parenting in vertebrate diversity are still contentious.

Thin terrestrial sediment deposits on intertidal sandflats: effects on pore-water solutes and juvenile bivalve burial behaviour [PDF]

open access: yesBiogeosciences, 2014
Nearshore zones experience increased sedimentation due to coastal development and enhanced loads of fine terrestrial sediment (hereafter, TS) in river waters. Deposition of TS can alter seabed biogeochemical processes but the effects on benthic ecosystem

TERRESTRIAL MOLLUSKS OF NEOGENIC DEPOSITS Of UKRAINE [PDF]

open access: yesGeological Journal, 2020
For the first time, we present the most complete list of the terrestrial mollusks from Neogenic deposits of Ukraine (more than 166 species that belong to 43 genera from 30 families). In the future, after the completion of a revision, this list will be significantly supplemented. By the systematic composition and considering the age-related, ecological,

A newly recognized theropod assemblage from the Lewisville Formation (Woodbine Group; Cenomanian) and its implications for understanding Late Cretaceous Appalachian terrestrial ecosystems [PDF]

open access: yesPeerJ, 2022
While the terrestrial fossil record of the mid-Cretaceous interval (Aptian to Cenomanian) in North America has been poorly studied, the recent focus on fossil localities from the western United States has offered a more detailed picture of vertebrate ...

The Mosquito

open access: yesEDIS, 2011
Mosquitoes are some of the most versatile organisms on earth. They can reproduce in virtually any natural or man-made deposit of water and have been found in mines deep below the surface, in mountain peaks, in highly polluted water bodies, in snow pools,

Evidence for fungi and gold redox interaction under Earth surface conditions

open access: yesNature Communications, 2019
The role of fungi in the biogeochemical cycling of gold remains unclear. Here the authors show that fungi can initiate gold oxidation under supergene conditions, thereby impacting gold mobilisation and secondary deposit formation in terrestrial ...

Food manipulation and selection in the omnivorous grapsoid crab Neohelice granulata (Decapoda: Varunidae)

open access: yesScientia Marina, 2014
Neohelice granulata is an omnivorous, semi-terrestrial burrowing crab endemic to southwestern Atlantic saltmarshes that behaves as a herbivore when it inhabits vegetated saltmarsh areas or a deposit feeder on bare mudflats. In order to gain insights into

Lamination and Its Impact on the Physical and Mechanical Properties of the Permian and Triassic Terrestrial Sandstones

open access: yesResources, 2021
The sandstones with a laminated structure are common building materials. Lamination is macroscopically expressed as colour and grain size variations observed both in the deposit and within individual beds; therefore, the properties of such sandstones are
