  This important article provides insights into the neural centers and hormonal modulations underlying seasonal changes associated with photoperiod-induced life-history states in birds. The physiological and transcriptomic analyses of the mediobasal hypothalamus and pituitary gland offer convincing evidence for a timing mechanism for measuring day length, which is relevant for the field of seasonal biology. The study's experiments and findings have the potential to captivate the attention of molecular and organismal endocrinologists and chronobiologists.

  This Research Advance provides compelling evidence connecting the ancient Egyptian trade of baboons with the ancient port city of Adulis. Combining ancient DNA methods from a single mummified baboon with historical accounts, this work fundamentally advances our understanding of the ancient baboon trade in the Red Sea. Some additional reporting of DNA contamination will make the evidence provided even stronger.

Sensory conflict disrupts circadian rhythms in the sea anemone Nematostella vectensis

  eLife assessment

  Understanding the integration and contribution of different combinations of environmental cues to the synchronization of the daily oscillator is important, because it provides insight into how organisms might be able to distinguish (and weight) between irregular (or in the tidal zone highly complex) versus regular individual daily changes of light and temperature. The study, which is thoroughly conducted and provides an impressive amount of experimental and analytical work, dissects the effects of sensory conflict on behavior and gene expression rhythms.

  Evaluation Summary:

  The hypoxia inducible factor (Hif) pathway was defined based on its role in cellular adaptation to hypoxia. In this paper, the authors examine the function of the pathway under 'physiological' normoxia in highly aerobic locust flight muscle. They find that a muscle-specific variant, Hif-1alpha2, is induced extensively by flying. By integrating bioinformatic analyses, measurements of gene expression and regulation, metabolites as well as redox regulation and flight assays, it is shown that Hif-1alpha2 plays an important role in sustaining prolonged flight by promoting glucose oxidation and upregulating a reactive oxygen species quencher (DJ-1). This study demonstrates the physiological requirement for two Hif-1a variants in a highly aerobic tissue in migratory locusts, a species that is both physiologically fascinating and a major agricultural pest. The work will be of interest to colleagues studying the physiology of muscles and flight.

Roosting ecology and the evolution of bat landing maneuvers

• Curated by eLife

  Evaluation Summary:

  Bat landings are remarkable because they are typically inverted and can involve two, three or four limbs securing the substrate, ranging from cave ceilings to leaves. How different bat species accomplish landing in such a remarkable dynamic fashion and how this ability may have evolved is a mystery. Boersma and Swartz resolved this question by studying how a wide range of bat species land in a unique biomechanics field study conducted across the world, which they complemented with a phylogenetic analysis that provides new insights into how bat landing behavior may have evolved in relation to substrate mechanics. The new evolutionary insight into how bat landing style relates to peak substrate contact force will be of interest to comparative biomechanists, movement ecologists and evolutionary biologists alike. Finally, the markedly different landing strategies for complex natural surfaces may inspire roboticists to design more effective landing and grasping solutions for complex surfaces.
