On the Potential for Bioenergy and Biofuels from Hydrothermal Vent Microbes [PDF]

open access: yesOceanography, 2012
The discovery of deep-sea hydrothermal vents caused scientists to reconsider their notions about life in the deep sea. In these seemingly inhospitable environments, free-living microbes, as well as microbial-animal symbioses, thrive in the warm waters ...

The singing phenology of Bachman's sparrow: implications for monitoring programs

open access: yesWildlife Society Bulletin, EarlyView.
We used automated recording units, weather data, and multiple logistic regression with generalized estimating equations to determine the annual singing period and influences on singing behavior of Bachman's sparrow in Texas, USA, surveying daily for 2 years.

Pulsated Global Hydrogen and Methane Flux at Mid‐Ocean Ridges Driven by Pangea Breakup

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Molecular hydrogen production occurs through the serpentinization of mantle peridotite exhumed at mid‐ocean ridges. Hydrogen is considered essential to sustain microbial life in the subsurface; however, estimates of hydrogen flux through geological time ...

Deep blueprint: A literature review and guide to automated image classification for ecologists

open access: yesJournal of Animal Ecology, EarlyView.
A practical, literature‐grounded review that gives ecologists a clear, modular workflow for deep learning image classification. With code, GUIs and a novel deep sea case study (automated deep sea biotope classification) it lowers technical barriers and provides a usable blueprint for accelerating, standardising, and scaling ecological image analysis ...

Partial Melting of Lower Oceanic Crust Gabbro: Constraints From Poikilitic Clinopyroxene Primocrysts

open access: yesFrontiers in Earth Science, 2018
Successive magma batches underplate, ascend, stall and erupt along spreading ridges, building the oceanic crust. It is therefore important to understand the processes and conditions under which magma differentiates at mid ocean ridges.

Not all Temperature Shocks are Alike: Disentangling Heat and High Temperature Shocks and Their Effects on Inflation in Australia

open access: yesEconomic Record, EarlyView.
We study the effects of heat and high temperature shocks on inflation in Australia using monthly, state‐level temperature anomaly data via two stages. In the first stage, we decompose temperature anomalies into orthogonal components using a structural vector autoregression with long‐run restrictions.

Diffuse Flow On and Around Hydrothermal Vents at Mid-Ocean Ridges [PDF]

open access: yesOceanography, 2012
Black smokers are the dramatic result of seawater being heated to high temperatures (generally 250° to 350°C) by magmatic systems, then discharging at the seafloor.

Water Use Behavior of Individual Birds: Ring Ouzels in an Arid High‐Mountain Ecosystem

open access: yesIntegrative Zoology, EarlyView.
Water is a limiting resource for birds in arid ecosystems. Individual birds differ strongly in how they use shared water sources, with drinking behavior increasing with temperature. Behavioral differences, hierarchy, and social context ultimately shape unequal access to water within the population. ABSTRACT Water availability strongly constrains animal

Between the Indian Ocean and the Gulf: Ceramics From Ḥattā Oasis in the Emirate of Dubai

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT This study presents the ceramic finds from archaeological investigations conducted in 2024 at two settlements: ‘Islamic Village' and Suhaila 2, one of a number of mountain villages of the Late Islamic period within the Ḥattā Oasis: a high‐altitude exclave in the Emirate of Dubai. The sites are located on the northeastern slopes of Jabal Qallāt

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

open access: yesBoreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...
