A deep‐sea sulfate‐reducing bacterium generates zero‐valent sulfur via metabolizing thiosulfate

open access: yesmLife, 2022
Zero‐valent sulfur (ZVS) is a crucial intermediate in the sulfur geobiochemical circulation and is widespread in deep‐sea cold seeps. Sulfur‐oxidizing bacteria are thought to be the major contributors to the formation of ZVS.

a low-activity cold seep in the Larsen B area, western Weddell Sea, Antarctica [PDF]

open access: yes, 2008
First videographic indication of an Antarctic cold seep ecosystem was recently obtained from the collapsed Larsen B ice shelf, western Weddell Sea (Domack et al., 2005).

The 9+ month marathon: How pregnancy may have shaped human endurance capacities

open access: yesThe Anatomical Record, EarlyView.
Abstract Anthropology has long considered the evolution of our uniquely human endurance capacities to be the result of selection upon anatomical and physiological features imposed by the demands of thermoregulation and resource acquisition, particularly during the demands of persistence hunting. Research has focused on the anatomical changes present in

Tubular carbonate concretions as hydrocarbon migration pathways? Examples from North Island, New Zealand [PDF]

open access: yes, 2006
Cold seep carbonate deposits are associated with the development on the sea floor of distinctive chemosyn¬thetic animal communities and carbonate minerali¬sation as a consequence of microbially mediated anaerobic oxidation of methane.

Community Characteristics and Genetic Diversity of Macrobenthos in Haima Cold Seep

open access: yesFrontiers in Marine Science, 2022
Knowledge about community structure and genetic diversity can help assess the potential for change in the loss and restoration of biodiversity, thereby facilitating effective management and ecosystem protection.

The fossil record stays silent: Confusions and conundrums for hominin pelvis evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The evolution of the hominin pelvis is commonly modeled as a series of stages driven largely by the requirements of bipedal locomotion, reproduction, thermoregulation, and pelvic floor muscular support. These patterns are complicated by variation in canal dimensions in relationship with different changes in overall pelvic breadths. To quantify

New nematode species and genera (Nematoda: Chromadorea) from cold seeps on Hikurangi Margin, New Zealand

open access: yesEuropean Journal of Taxonomy, 2023
Relatively little is known about the taxonomy and ecology of deep-sea nematode species inhabiting cold seep habitats. The available data show that cold seep nematode communities are typically characterized by low diversity and are often dominated by a ...

Note on paramoudra-like carbonate concretions in the Urenui Formation, North Taranaki: possible plumbing system for a Late Miocene methane seep field [PDF]

open access: yes, 2004
A reconnaissance study of calcitic and dolomitic tubular concretions in upper slope mudstone of the Late Miocene Urenui Formation exposed along the north Taranaki coastline indicates that they have a complex diagenetic history involving different phases ...

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Characterisation of the nematode community of a low-activity cold seep in the recently ice-shelf free Larsen B area, Eastern Antarctic Peninsula. [PDF]

open access: yesPLoS ONE, 2011
BACKGROUND: Recent climate-induced ice-shelf disintegration in the Larsen A (1995) and B (2002) areas along the Eastern Antarctic Peninsula formed a unique opportunity to assess sub-ice-shelf benthic community structure and led to the discovery of ...
