Fungi that produce mushrooms have a unique life cycle with two haploid nuclei, instead of a diploid nucleus, this allows additional matings and selection at the level of the nucleus, even with a fitness trade-off.
The tooth replacement pattern of early-diverging ceratopsians helps to understand the origin of the specialized dental system of ceratopsids and provides new insights to feeding strategy transition.
Evidence for a largely unexplored radiation of squamates (lizards, snakes, and amphisbaenians) in the Middle to Late Jurassic is revealed by analyses of morphospace expansion, disparity, and evolutionary rates.
Delineating Episyrphus balteatus transregional movements and pollination networks advance a deep understanding of its migration ecology and facilitate the design of targeted strategies to conserve and enhance its ecosystem services.
New digital restorations indicate that the structure and function of the shoulder joint were highly variable among Early Cretaceous birds, with such key features as the configuration of the triosseal canal and the nature of scapula-coracoid articulation showing considerable diversity.

Acetylation of nuclear basket components, following their interaction with accumulating extrachromosomal DNA circles, drives the reorganization of nuclear pore complexes and the loss of cellular viability associated with replicative ageing.

Wings achieve plasticity in size while maintaining robust pattern via ecdysone, which elicits graded responses for growth rates and threshold responses for patterning rates, in the fruit fly Drosophila melanogaster.
The fate of duplicated transcription factors within budding yeast is described, providing insights into the mechanisms that shape transcriptional networks during evolution.

Lifelong continuous reproduction, late-life investment into female sexuals, a short phase of senescence, and reproductive death characterize the life history of Cardiocondyla obscurior ant queens.
