Rare study showing that #microplastics in #benthic sediments affect the relationship with 🦪Macomona liliana & impair the deep-burrowing behaviour of 🪱Macroclymenella stewartensis, likely influencing key ecosystem functions such as benthic O2 fluxes & nitrogen cycling.

Why the Shape of Continents Mattered Across 500 Million Years of Climate Change New fossil evidence shows how geography influenced who survived Earth’s climate shifts

Extinction isn’t random.

Range size matters. Temperature tolerance matters. Climate change matters.

But there’s another piece we’ve long suspected: geography.

For 500 million years, the shape of continents helped shape survival.

Banerjee et al. propose that the underlying structure of positive feedbacks in an ecosystem may determine the tipping-evasion mechanism relevant to that particular system.

New behavioral #paleontology paper out today about tyrannosaur predation! The authors (Wyenberg-Henzler & Scannella) contend that the find is "consistent with a bite inflicted during an attempt to control the struggling Edmontosaurus or deliver a killing blow followed by carcass consumption". Nice!

Mapping tipping risks from Antarctic ice basins under global warming - Nature Climate Change Climate change threatens the future of the Antarctic Ice Sheet. Here the authors show that individual drainage basins have different thresholds and loss patterns, suggesting the need to consider the d...

Antarctica isn’t one big tipping point.

New research maps 18 separate ice basins, each with its own threshold. Some in West Antarctica may tip at just ~1–2C warming (i.e close to today’s levels).

Porpoises 'buzz' less when boats and ships are nearby.

Researchers studying a narrow strait called the Little Belt in Denmark found buzzes reduced by up to 45% during the busiest vessel traffic periods.

Hydrostatic pressure induces strong leakage of dissolved organic matter from “marine snow” particles Particles sinking into the deep ocean come under pressure and leak dissolved organic matter, which affects marine carbon cycling.

Not all marine snow—oceanic dandruff made of fecal flakes, dead phytoplankton, and more—makes it to the seafloor.

Researchers in #ScienceAdvances describe the deep-sea squeeze that causes carbon from these particles to leak into seawater before reaching the ocean’s bottom. https://scim.ag/3Zh1kCU

Increasing bottom marine heatwaves pose a critical risk to Mediterranean benthic species Konsta et al. assess the exposure of Mediterranean benthic species to projected marine heatwaves occurring at the seafloor. Their analysis reveals that current and future habitats of these species will experience long-lasting, intensifying bottom marine heatwaves. This reflects a basin-wide pattern where, by the end of the century, extreme bottom marine heatwaves are expected year-round. Their findings underscore the necessity for targeted conservation strategies to mitigate heatwave impacts on Mediterranean benthic species.

Species shift their ranges in response to climate change, but many can't keep up. The resulting "community-climate disequilibrium" can impair ecosystem function and cause counterintuitive dynamics, like short-term gain but long-term loss onlinelibrary.wiley.com/doi/10.1111/...

Revealing the hidden patterns of shark and ray diversity over the past 145 million years Gardiner et al. reconstruct the diversity of sharks and rays across the past 145 million years using deep learning and an extensive dataset. Their results unveil previously hidden patterns, including ...

Our new paper is online! We found that 1) today's shark & ray diversity was already reached ~100Ma; 2) that the K/Pg extinction was not catastrophic; 3) that the max diversity was reached ~50Ma; and 4) that today's diversity is depleted compared to the past.

This is figure 2, which shows scaled bottom-up emissions and comparison with top-down and bottom-up estimates.

Microplastic emissions into the air from land sources are estimated to be about six hundred quadrillion particles per year, which is more than 20 times larger than emissions from the oceans, according to an analysis in Nature. go.nature.com/4jWQCei
