    • Ambient Temperature Effects on the Spring and Autumn Somatic Growth Trajectory Show Plasticity in the Photoneuroendocrine Response Pathway in the Tundra Vole 

      van Dalum, Mattis Jayme; van Rosmalen, Laura; Appenroth, Daniel; Cazarez Marquez, Fernando; Roodenrijs, Renzo T. M.; de Wit, Lauren; Hut, Roelof A.; Hazlerigg, David Grey (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-11)
      Seasonal mammals register photoperiodic changes through the photoneuroendocrine system enabling them to time seasonal changes in growth, metabolism, and reproduction. To a varying extent, proximate environmental factors like ambient temperature (Ta) modulate timing of seasonal changes in physiology, conferring adaptive flexibility. While the molecular photoneuroendocrine pathway governing the seasonal ...

    • Biological timekeeping in polar environments: lessons from terrestrial vertebrates 

      Hazlerigg, David Grey; Mizumo Tomotani, Barbara; West, Alexander Christopher; Appenroth, Daniel; Wood, Shona Hiedi (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-30)
      The polar regions receive less solar energy than anywhere else on Earth, with the greatest year-round variation in daily light exposure; this produces highly seasonal environments, with short summers and long, cold winters. Polar environments are also characterised by a reduced daily amplitude of solar illumination. This is obvious around the solstices, when the Sun remains continuously above (polar ...

    • Gerald Lincoln: A man for all seasons 

      Ebling, Francis J.P.; Fletcher, John; Hazlerigg, David Grey; Loudon, Andrew S.I. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-04)
      Gerald Anthony Lincoln died after a short illness on 15 July 2020 at the age of 75 years. Gerald was Emeritus Professor of Biological Timing at Edinburgh University and a Fellow of the Royal Society of Edinburgh. He was an outstanding scientist and naturalist who was a seminal figure in developing our understanding of the neuroendocrine mechanisms underlying seasonal rhythmicity. This review considers ...

    • Mechanisms of temperature modulation in mammalian seasonal timing 

      van Rosmalen, Laura; van Dalum, Mattis Jayme; Appenroth, Daniel; Roodenrijs, Renzo T. M.; de Wit, Lauren; Hazlerigg, David Grey; Hut, Roelof A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-29)
      Global warming is predicted to have major effects on the annual time windows during which species may successfully reproduce. At the organismal level, climatic shifts engage with the control mechanism for reproductive seasonality. In mammals, laboratory studies on neuroendocrine mechanism emphasize photoperiod as a predictive cue, but this is based on a restricted group of species. In contrast, ...
