Read the free Plain Language Summary for this article on the Journal blog. Abstract Studies have shown that organisms may adjust metabolic rates in response to thermal variability, highlighting metabolic plasticity as a key adaptive mechanism. Understanding the extent of metabolic plasticity of an organism is key to predicting its adaptation to climate

短尾秀体溞(Diaphanosoma brachyurum)是东湖6—9月的优势种群。作者在实验室恒温条件下,观察了它的发育与生长。这种溢的卵与胚胎发育时间随温度升高而缩短。卵与胚胎发育时间(D)与温度(T)间的迥归方程为: logD=2.0195-1.3784logT 短尾秀体溞的生长速度随龄数而变化,一般可分为3个时期:幼龄为高速生长期,成龄前期为中速生长期,后期则为缓慢生长期。在25℃时有4个幼龄,10个成龄;而在30、35℃时有3个幼龄,12或11个成龄。幼龄的脱皮频率远大于成龄 ...

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...
