Pulmonary development in Squamata: Insights from embryonic studies using micro‐CT

Developmental Dynamics, EarlyView.
Abstract Background Pulmonary development in tetrapods is a complex process, especially within squamates, where single‐chambered, transitional, and multi‐chambered lungs can be found in adult animals. While the embryological development of the respiratory system of lizards and snakes was studied in a number of species between the 1830s and 1940s, the ...

Tracing the origins and evolution of nymphalid butterflies (Lepidoptera) in the Atlantic Forest

Ecography, EarlyView.
Understanding the relative roles of diversification and dispersal is key to explaining large‐scale biogeographical patterns. Although both processes are known to shape biodiversity, their relative contributions remain understudied for many organisms. Here, we examine how these processes have jointly contributed to the exceptional diversity and endemism

Ground‐ and Excited‐State Mixed Valency in a 4,4′‐Bipyridine‐Bridged Bimetallic Di‐Ruthenium Complex

European Journal of Inorganic Chemistry, EarlyView.
Photoinduced mixed‐valence interactions across a 4,4′‐bpy bridge were studied. MLCT excited states in the bimetallic complex are longer‐lived than in the monometallic reference, thanks to metal–metal electronic coupling and hole delocalization, but are still shorter than the nanosecond timescale relevant for diffusional reactivity.

Phenolate‐ and Alcoholate‐Based Chromium N‐Heterocyclic Carbene Complexes: Structural Peculiarities, Magnetometric and Electron Paramagnetic Resonance Study, and Catalytic Ethylene Oligomerization

European Journal of Inorganic Chemistry, EarlyView.
The first low‐oxidation (I/III) state chromium‐complex bearing a O‐chelating NHC ligand has been synthesized and structurally characterized by single‐crystal X‐ray analysis. The formation of the mixed‐valence species was further supported by SQUID magnetometry and high‐field electron paramagnetic resonance (EPR) spectroscopy.
