蝠鲼的颅骨内热:生热大脑对进化和生态的影响。
蝠鲼和魔鬼鱼(Mobula spp.)的大脑体积大、新陈代谢旺盛,可能是一种致热器官,代表了鱼类颅内热的独特机理基础,可改善中枢神经系统在寒冷水域中的功能。在炎热的陆地环境中,早期类人猿可能受到热限制而无法进化出更大的大脑,而在寒冷的海洋水域中,鲸目动物和蝠鲼可能受到热驱动而增大了产热大脑。鲸目动物大脑增大可能产生颅内热和认知能力增强的双重结果,这表明其中一种可能是选择另一种机制的进化副产品,并强调了在将大脑大小转化为认知能力时考虑非认知功能的必要性。计算科学成像为解决紧迫的机理和系统发育问题提供了很好的途径,这些问题是评估鳞鳃亚纲动物的颅内温是温度驱动的选择结果这一理论所必需的。

Temporal niche dynamics of spreading native invertebrates underlie doubling of richness in pristine temperate streams. Human disturbance and aridity influence biomass harvesting by leaf-cutting ants with impacts on nutrient dynamics in a Caatinga dry forest. Correction to "Squamate metabolic rates decrease in winter beyond the effect of temperature". Sex-dependent effects of infection on guppy reproductive fitness and offspring parasite resistance. Global warming affects foraging efficiency of fish by influencing mutual interference.
