When Density Matters: Hydraulic and Salinity Evolution in Groundwater‐Fed Pit Lakes in Semiarid and Arid Climates

open access: yesGroundwater, EarlyView.
Pit lakes in semiarid and arid regions are often assumed to be terminal sinks for groundwater following mine closure. Using synthetic numerical modeling, we demonstrate that evaporation‐driven density gradients can reverse this behavior, transforming pit lakes into throughflow systems and potentially increasing salinity in adjacent aquifers.

Diversity of meiofauna at deep-sea hydrothermal vents and cold seeps with particular reference to nematodes

open access: yes, 2007
Deep-sea hydrothermal vents and cold seeps are remarkable for their spectacular megaandmacrofauna, many of which appear to have a high level of endemism to these chemosyntheticenvironments.

Simulating the Impacts of Deep Geothermal Development on Shallow Hydrothermal Resources in a Rocky Mountain Rift Valley

open access: yesGroundwater, EarlyView.
Abstract Numerical modeling has been widely used to assess the feasibility of geothermal energy development at sites across the world, but modeling applications simulating the potential impacts on shallow hydrothermal resources and surface water are relatively scarce. In this study, we apply the MODFLOW 6 groundwater energy (GWE) code to simulate fully

Meiofauna and nematodes in cold seep surface sediments collected during Maria S. Merian cruise MSM13 to the Eastern Mediterranean area

open access: yes, 2014
In this study the importance of spatial scales on nematode species distribution and patterns of biodiversity and turnover in cold seeps was investigated.

Reconnaissance‐Scale Methods for the Identification of Groundwater Discharge to Streams

open access: yesGroundwater Monitoring &Remediation, EarlyView.
Abstract Identifying groundwater discharge locations is critical for understanding and monitoring groundwater contributions to streams in terms of water quantity and quality. Streams and rivers are under increasing strain from factors, including increased urbanization, agricultural land use, groundwater extraction, and climate change, which can alter ...

Thermogenesis‐derived spatiotemporal microclimates guide pollinator movement to ensure pollination

open access: yesJournal of Integrative Plant Biology, EarlyView.
Alocasia odora's microclimatic heterogeneity guides Colocasiomyia fly movement within its inflorescence. During the female stage, midday heat in the upper spadix pushes flies down to the cooler female zone. During the male stage, nocturnal warmth in the upper part pulls flies upward and spathe constriction closes the lower female chamber.

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

open access: yesCommunications 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 ...

Understanding marine biodiversity patterns and drivers: The fall of Icarus

open access: yesMarine 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.

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

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 ...

Mapping of Fire Blight Resistance QTL in the European Pear (Pyrus communis L.) Cultivar ‘Petersbirne’

open access: yesPlant Breeding, EarlyView.
ABSTRACT The breeding of pear (Pyrus communis) cultivars that meet market requirements and are at the same time resistant to fire blight is a challenging task beacuse appropriate resistance donors are scarce. To identify valuable resistance sources, phenotypic screening and genetic characterization are indispensable.
