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 ...

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 ...

Comparing species accumulation within taxonomically well‐ and poorly resolved insect groups over 37 years

open access: yesInsect Conservation and Diversity, EarlyView.
Here, we used a unique 37‐year (1969–2006) freshwater macroinvertebrate time‐series, collected over seven sites in central Germany, to study biodiversity patterns and species accumulation over time. Accumulation curves of Diptera diversity have not reached a plateau in 37 years of sampling.

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

open access: yesResearch
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 ...

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.

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.

Oral Soft Tissue Biopsy in Patients Receiving Direct Oral Anticoagulants: A Prospective Cohort Study on Bleeding Outcomes

open access: yesOral Diseases, EarlyView.
ABSTRACT Background Direct oral anticoagulants (DOACs) are the first‐line therapy for stroke prevention in non‐valvular atrial fibrillation and venous thromboembolism. While evidence supports their continuation during routine dental procedures such as tooth extractions, data on oral soft tissue biopsies remain limited.

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.

No need to seed: restoring species‐rich grassland on former arable fields by natural regeneration

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Over the last century, agricultural intensification has caused substantial losses of semi‐natural species‐rich grasslands. One means of restoring grassland habitat is to abandon farmed land, followed by mowing and/or grazing of the established vegetation to facilitate meadow diversification. Objectives This study investigated post‐

Utopia Remembers: The Soviet Past in the Imagined Communist Future

open access: yesThe Russian Review, EarlyView.
Abstract After a twenty‐five‐year hiatus, the reappearance of utopian literature in 1957 prompted Soviet literary watchdogs to corral the subgenre into an ideologically‐acceptable mold. A key requirement was for future generations to be depicted as reverently commemorating the past.
