A Molecular‐Scale Understanding of Misorientation Toughening in Corals and Seashells

Advanced Materials, Volume 35, Issue 28, July 13, 2023., 2023
Coral skeletons and nacre (left and right, respectively) have distinct structures, but they share slight misorientation of adjacent crystals, as displayed in these maps where color represents crystal orientation, and as measured in the histogram (center bottom).

A possible home for a bizarre Carboniferous animal: is Typhloesus a pelagic gastropod? [PDF]

, 2022
By contrast to many previously enigmatic Palaeozoic fossils, the Carboniferous metazoan Typhloesus has defied phylogenetic placement. Here, we document new features, including possible phosphatized muscle tissues and a hitherto unrecognized feeding ...

A guide to area‐restricted search: a foundational foraging behaviour

Biological Reviews, Volume 97, Issue 6, Page 2076-2089, December 2022., 2022
ABSTRACT Area‐restricted search is the capacity to change search effort adaptively in response to resource encounters or expectations, from directional exploration (global, extensive search) to focused exploitation (local, intensive search). This search pattern is used by numerous organisms, from worms and insects to humans, to find various targets ...

Association between shell morphology of micro-land snails (genus Plectostoma) and their predator’s predatory behaviour [PDF]

, 2014
Predator–prey interactions are among the main ecological interactions that shape the diversity of biological form. In many cases, the evolution of the mollusc shell form is presumably driven by predation.

Late Quaternary mud‐dominated, basin‐floor sedimentation of the Gulf of Corinth, Greece: Implications for deep‐water depositional processes and controls on syn‐rift sedimentation

Basin Research, Volume 34, Issue 5, Page 1567-1600, October 2022., 2022
Late Quaternary syn‐rift basinal deposits in the Gulf of Corinth, Greece, are analysed using IODP Expedition 381 boreholes. Stratigraphic packages of mud‐dominated deposits record distinct hydrological conditions related to global sea‐level interacting with highs at the ends of the rift, highlight rift segment boundaries as controls on stratigraphy in ...

Biomineralized Materials as Model Systems for Structural Composites: 3D Architecture

Advanced Materials, Volume 34, Issue 20, May 19, 2022., 2022
Biomineralized load‐bearing materials are intrinsically 3D composites and are widely used as model systems for developing novel structural materials with improved mechanical performance. This review presents recent progress in understanding the 3D architectural design of biomineralized composites.

Luminescence dating of sand wedges constrains the Late Wisconsin (MIS 2) permafrost interval in the upper Midwest, USA

Boreas, Volume 51, Issue 2, Page 385-401, April 2022., 2022
Large parts of the upper Midwest, USA were impacted by permafrost during the Last Glacial Maximum (LGM). Even though permafrost persisted as the Laurentide Ice Sheet began to recede, direct age control of this interval is largely lacking. To better temporally constrain the permafrost interval in western Wisconsin, we identified two sites, outside the ...
