Haptic Perception via the Dynamics of a Flexible Body Inspired by an Ostrich's Neck

Advanced Intelligent Systems, EarlyView.
Inspired by avian anatomy, this study uses a flexible robotic neck to investigate haptic perception driven by musculoskeletal dynamics. By applying physical reservoir computing, the robot encodes external force interactions into its body dynamics, allowing effective object classification.

Zwitterionic Heavier Pnictinidenes in Redox Catalysis

Angewandte Chemie, EarlyView.
Zwitterionic pnictinidenes: A new class of zwitterionic heavier pnictogen species stabilized by bis(N‐heterocyclic carbene)borate ligands is reported, enabling the isolation of Sb and Bi in multiple oxidation states. These thoroughly characterized systems exhibit cationic character and engage in redox catalysis, facilitating catalytic ...

Extreme fire severity interacts with seed traits to moderate post‐fire species assemblages

American Journal of Botany, EarlyView.
Abstract Premise Climate change is globally pushing fire regimes to new extremes, with unprecedented large‐scale severe fires. Persistent soil seed banks are a key mechanism for plant species recovery after fires, but extreme fire severity may generate soil temperatures beyond thresholds seeds are adapted to.

C(sp2)─H Bond Activation with a Heterometallic Nickel–Aluminium Complex

Angewandte Chemie, EarlyView.
Despite the prevalence of Ni/Al catalysts for pyridine C─H functionalization, mechanistic details of such systems remain scarce. Herein, we present the discovery of PCy3‐catalyzed bond‐breaking and making processes that occur in the coordination sphere of a novel Ni─Al heterometallic complex.

Modeling seasonal vegetation phenology from hydroclimatic drivers for contrasting plant functional groups within drylands of the Southwestern USA

Environmental Research: Ecology, 2023
In dryland ecosystems, vegetation within different plant functional groups exhibits distinct seasonal phenologies that are affected by the prevailing hydroclimatic forcing.

Stomatal distribution and post‐fire recovery: Intra‐ and interspecific variation in plants of the pyrogenic Florida scrub

American Journal of Botany, EarlyView.
Abstract Premise Amphistomy, the presence of stomata on both leaf surfaces, can increase photosynthesis yet is uncommon across vascular plants. The relative infrequency of amphistomy is often attributed to high costs, such as transpirational water loss.

Toward a macroevolutionary understanding of live‐leaf flammability in plant species of fire‐prone forests

American Journal of Botany, EarlyView.
Abstract Premise The flammability of live leaves in canopies varies considerably among plant species. Identifying macroevolutionary processes that shape variation in leaf flammability contributes to an understanding of the phylogenetic underpinnings of wildfire dynamics.
