Five Decades of Dispute: A Triptych. E. J. Corey

The Chemical Record, EarlyView.
In his 2004 Priestley Medal address, E. J. Corey stated, “On May 4, 1964, I suggested to my colleague R. B. Woodward a simple explanation involving the symmetry of the perturbed (HOMO) molecular orbitals for the stereoselective cyclobutene/1,3‐butadiene and 1,3,5‐hexatriene/cyclohexadiene conversions that provided the basis for the further development ...

Phytoplankton Tune Local pH to Actively Modulate Circadian Gravitactic Behavior

Advanced Physics Research
Diel vertical migration (DVM) is the daily movement of motile phytoplankton between light‐rich surface waters and deeper nutrient‐rich layers, typically governed by internal clocks. However, many species show irregular patterns that deviate from expected

Four‐dimensional immuno‐mechanobiomaterials: Dynamic material cues that program host response to prevent fibrosis and enable regeneration

VIEW, EarlyView.
Dynamic immuno‐mechanobiomaterials with time‐programmed mechanical adaptation orchestrate host responses through precise mechanotransduction and immune‐stromal regulation. These adaptive biomaterials minimize mechanical mismatch, attenuate the forign dy response and fibrosis, promote angiogenesis and controlled extracellular matrix remodeling, and ...

Uncovering intra-daily intertidal biofilm dynamics in a shorebird foraging hotspot with hourly UAV multispectral imagery acquisitions

International Journal of Applied Earth Observations and Geoinformation
Estuarine mudflats are colonized by biofilm-forming microphytobenthos (MPB), which support primary production, stabilize sediment, and provide critical food for benthic invertebrates and shorebirds.

The influence of sea ice, wind speed and marine mammals on Southern Ocean ambient sound [PDF]

Royal Society Open Science, 2017
This paper describes the natural variability of ambient sound in the Southern Ocean, an acoustically pristine marine mammal habitat. Over a 3-year period, two autonomous recorders were moored along the Greenwich meridian to collect underwater passive ...

Optimising Connectivity in Deep‐Sea MPA Networks for Nephrops norvegicus Recovery in NW Mediterranean Sea [PDF]

Ecol Evol
In the NW Mediterranean, where the Norway lobster (Nephrops norvegicus) is both ecologically and economically important, larval connectivity in an existing network of Fishery No‐Take Zones was estimated using Lagrangian transport simulation informed by species‐specific habitat models.

Linking telemetry data with forage availability maps advances information for moose management

Wildlife Biology, EarlyView.
Evidence‐based forest and wildlife management requires precise estimates of forage availability for spatial planning and conflict mitigation. Recently, novel datasets and associated maps have been developed for use in Swedish forest and wildlife management.

Fishing Activity Affected Odontocete Cetacean Distribution in a Marine Protected Area in the East China Sea

Integrative Zoology, EarlyView.
Spatiotemporal distribution of odontocete cetaceans within China's Jiushan Archipelago National Nature Reserve was investigated. Fishing vessels significantly reduced both cetacean acoustic detections and feeding activity, whereas gillnets selectively suppressed cetacean feeding behavior without affecting overall cetacean detection rates.

Seasonal and diel patterns in Black Sea harbour porpoise acoustic activity in 2020–2022

Ecology and Evolution
The Black Sea is a semi‐enclosed inland sea with an unevenly distributed extensive coastal shelf area and anoxic deep waters. It is inhabited by common and bottlenose dolphins, as well as harbour porpoises, all represented by local subspecies.
