摘要

本研究调查了罕见的冬季晒太阳行为(在椴树蝽野生种群中观察到)和冬季变暖(气候模型预测)对椴树蝽越冬存活率和生理机能的影响。昆虫在实验室中暴露于模拟晒太阳和冬季变暖的情景中。部分昆虫在野外半自然条件下暴露于真实的冬季,以进行比较。结果表明,冬季晒太阳有明显的积极作用,这意味着晒太阳行为对蛙蛙的越冬存活至关重要。与此相反,冬季升温对越冬存活率有很大的负面影响,可能对欧洲中部的箭毒蛙种群构成威胁。本研究测量的生理参数(质量、含水量、SCP、能量储备)不能完全解释所有结果。还需要进一步研究,以更好地了解冬季晒太阳的积极影响和冬季变暖对越冬蛙的消极影响背后的机制。

Basking improves but winter warming worsens overwinter survival in the linden bug

The present study investigates the effects of rare winter basking behavior (observed in wild populations of the Linden bug, Pyrrhocoris apterus) and the effects of winter warming (predicted by climate models) on overwinter survival and physiology of P. apterus. The insects were exposed to scenarios simulating basking and winter warming in the laboratory. Part of the insects were exposed to real winters under semi-natural conditions in the field for comparison. The results show a clear positive effect of winter basking, implying that basking behavior is critical for overwinter survival in P. apterus. In contrast, winter warming was found to have a strong negative effect on overwinter survival, potentially representing a threat to central European populations of P. apterus. Physiological parameters (mass, water content, SCP, energy reserves) measured in this study cannot fully explain all the results. Further study is needed to better understand the mechanisms behind the positive effects of winter basking and the negative effects of winter warming on overwintering P. apterus.

期刊介绍: All aspects of insect physiology are published in this journal which will also accept papers on the physiology of other arthropods, if the referees consider the work to be of general interest. The coverage includes endocrinology (in relation to moulting, reproduction and metabolism), pheromones, neurobiology (cellular, integrative and developmental), physiological pharmacology, nutrition (food selection, digestion and absorption), homeostasis, excretion, reproduction and behaviour. Papers covering functional genomics and molecular approaches to physiological problems will also be included. Communications on structure and applied entomology can be published if the subject matter has an explicit bearing on the physiology of arthropods. Review articles and novel method papers are also welcomed.
