Land birds on atolls: diversity, origin, and function
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

ABSTRACT Introduction The prevalence of bioprosthetic aortic valve failure is increasing due to the broader use of bioprosthetic valves, both surgical and transcatheter, and an ageing population. Registry data indicate a higher risk of coronary obstruction and elevated gradients following valve‐in‐valve transcatheter aortic valve implantation (TAVI ...

As suggested by the titles of the two short stories analyzed in this article, Caroline Gordon cannot dissociate Southern places from several perceptions of Time which can be cyclical, linear, historical, or “uneventful”—a denial of the passing of time ...

The role of Rho GTPases in facial morphogenesis
The role of small GTPases, RHOA, RAC1, and CDC42 and pathway mediators is reviewed in the context of embryonic facial development. Lip fusion requires cytoskeletal remodeling during morphogenesis of the facial processes and during lip fusion. Fnm, frontonasal mass; lnp, lateral nasal process; mnp, medial nasal process; mxp, maxillary process; np, nasal

Abstract Background Elp1, a subunit of the Elongator complex, is essential for tRNA modification and neuronal development. Mutations in ELP1 underlie familial dysautonomia (FD), a disorder marked by sensory and autonomic neuropathy. While loss of Elp1 disrupts trigeminal ganglion formation and survival, the downstream molecular consequences remain ...

Abstract The olfactory placode (OP) generates a broad array of chemosensory neurons in the nasal region, including olfactory sensory neurons, vomeronasal sensory neurons, neurons of the septal organ, and Grueneberg ganglion. During invagination, the OP also generates migratory neuronal populations, including gonadotropin‐releasing hormone‐1 (GnRH‐1 ...

Abstract Background Developmental control of jaw size is crucial to prevent birth defects and facilitate evolutionary adaptation. We have shown that jaw size is established by neural crest mesenchyme (NCM), which are progenitor cells that migrate into the mandibular primordia and produce the jaws.

Predator–prey interactions are vital to ecosystem functioning but may be disrupted by climate change. We investigated a food‐web network involving three owl species over 24 years in a semi‐arid ecosystem at Bosque Fray Jorge National Park, Chile.

Understanding how global change reshapes mountain plant communities is essential for predicting biodiversity and ecosystem function in a warming world. Using resurvey data from over 1400 non‐forest vegetation plots across the European Alps, we show that community‐weighted means of key functional traits capturing important dimensions of plant ecological
