Decreasing Sociality With Body Size in All‐Male Groups of Sperm Whales (Physeter macrocephalus)
ABSTRACT The costs and benefits of group living can influence animal group size and social relationships, and these balance points may shift as animals mature. Young male sperm whales (Physeter macrocephalus) appear to form stable all‐male groups unrelated to direct defense of females or territories, but quantitative data on how sociality changes with ...

Long‐read whole‐genome sequencing revealed extensive chromosomal rearrangements and aneuploidy in a widely used Chlamydomonas reinhardtii stt7‐1 mutant. The STT7 gene (shown in red) was found to be split between two rearranged chromosomes, providing a molecular explanation for the long‐standing failure of this mutant in genetic crosses.

Tip Quantification enables quantitative analyses over versatile selections of regions of interest. Summary Cell polarity and tip growth rely on the dynamic spatial organization of signaling and structural components. Quantitative characterization of these spatiotemporal dynamics is critical for understanding polarized cell growth, yet manual ...

SUMMARY CYP73 and CYP98 are two cytochrome P450 monooxygenase families present in bryophytes and tracheophytes, and they play key roles in the formation of phenolic compounds containing a caffeic acid moiety and more complex phenolic compounds. CYP73 encodes the second enzyme in the core phenylpropanoid pathway and is the first enzyme family in this ...

Humanin ameliorates diabetes‐induced testicular damage in a streptozotocin‐induced mouse model
Abstract Diabetes mellitus is a major metabolic disorder closely associated with oxidative stress and male reproductive dysfunction. Humanin, a mitochondria‐derived peptide, has been reported to exert cytoprotective, anti‐apoptotic and antioxidant effects in various disease models; however, its role in diabetes‐induced testicular damage remains unclear.

Psychological and Physiological Adaptations to Sperm Competition in Humans [PDF]
Postcopulatory competition between males, in the form of sperm competition, is a widespread phenomenon in many animal species. The extent to which sperm competition has been an important selective pressure during human evolution remains controversial ...

Sperm competition and ejaculate economics
Sperm competition was identified in 1970 as a pervasive selective force in post‐copulatory sexual selection that occurs when the ejaculates of different males compete to fertilise a given set of ova. Since then, sperm competition has been much studied both empirically and theoretically.
