Commentary: The missing sabertooth baculum—At what point might the absence of evidence reasonably be considered evidence of absence?

open access: yesThe Anatomical Record, EarlyView.
Abstract Most carnivorans and all modern felids have ossified bacula; however, no machairodont baculum has ever been identified. This is true despite the many fairly complete skeletons found around the world of several sabertooth taxa. Although the bacula of modern felids are much smaller than those of canoids (even the least weasel's baculum is longer

Climate change–induced terrestrial matter runoff may decrease food web production in coastal ecosystems

open access: yesLimnology and Oceanography, EarlyView.
Abstract Climate change is projected to cause elevated precipitation in northern Europe, leading to increased runoff of terrestrial matter to coastal areas. The consequences for food web production and ecosystem function remain unclear. A mesocosm experiment was performed to investigate the impacts of elevated terrestrial matter input, using a natural ...

Production and fate of macroalgal carbon in the ocean: How much do macroalgal organics matter?

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract Global carbon sequestration by macroalgae is hypothesized to rival rates in other blue carbon ecosystems. However, quantifying macroalgal carbon sequestration is challenging as it is hypothesized to occur outside macroalgal ecosystems, with 73% of sequestration occurring when dissolved organic carbon (DOC) is exported to deep ocean waters.

Evaluation of a modified sequential P extraction protocol: Quantification of Fe(II)‐P as a separate phase in seven different freshwater sediments

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Sequential phosphorus (P) extraction (SPE) is a well‐established and widely applied method for quantitatively and qualitatively determining the critical nutrient P in freshwater sediments. It allows the estimation of P bioavailability and facilitates the evaluation of the long‐term effects of eutrophication mitigation measures.

Improvement of water absorption behavior and mechanical properties of woven jute fiber‐reinforced epoxy composites with waste eggshell filler

open access: yesPolymer International, EarlyView.
This study investigates the influence of waste eggshell powder on the water absorption and mechanical properties of jute fiber‐reinforced epoxy composites. Optimal eggshell filler content (2 wt%) significantly enhances composite performance by reducing water absorption and improving mechanical properties.

Optical properties and compositions of dissolved organic matter (DOM) along trophic gradients: Implications for a COD proxy in urban lakes

open access: yesRiver, EarlyView.
Abstract Aiming to control lake eutrophication, proposed methods for convenient and faithworthy lake water quality evaluation are warranted. Optical measurement of dissolved organic matter (DOM) demonstrates great potential for estimating organic matter (OM) composition, and can thus serve as a proxy for conventional chemical oxygen demand (CODMn ...

A path towards appropriate degradation experiments for assessing carbon sequestration potential of macroalgae

open access: yesJournal of Ecology, EarlyView.
We systematically reviewed literature on macroalgal degradation. To date, most degradation experiments are carried out in aquaria or shallow environments, span short timescales or rarely incorporate environmental gradients driving degradation. Degradation rates were higher in intertidal versus subtidal habitats, for pre‐treated algal tissue compared to

Comparison of Two Methods for Determination of Rhenium and Platinum‐Group Elements in Meteorites Using On‐Line and Off‐Line Matrix Separation Modes

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points PEEK tubing has been observed to adsorb Pd and Pt ions, resulting in significantly reduced recoveries of Pd and Pt elements. HPA‐S provides a more effective dissolution for meteorite samples than Carius tube digestion, resulting in higher mass fractions for PGE.
