关于荷尔蒙皮质酮（CORT）如何介导繁殖期间的能量消耗，人们提出了不同的假设。基线皮质酮（CORTb）的升高可能会支持每日能量消耗（DEE），促进繁殖努力，或降低低质量个体在面临静力超载时的代价高昂的行为。我们研究了 CORTb、时间活动预算（TABs）、DEE 和潜水行为之间的关系，这些关系跨越了两年时间和小赤麻鸭（Alle alle）的群落，小赤麻鸭是一种北极海鸟，面对气候变化，提高 DEE 可能有助于其繁殖。我们还探讨了汞（Hg）污染是否会通过影响下丘脑-垂体-肾上腺（HPA）轴和CORT的产生来抑制DEE。此外，我们还对繁殖海鸟物种进行了系统发育控制分析，以更广泛地了解 CORT 与 DEE 的关系。在东格陵兰岛寒冷的一年中，CORTb与小赤麻鸭的活动、DEE和潜水持续时间呈正相关，当时小赤麻鸭种群中的CORTb升高，但在温暖的一年中或在斯瓦尔巴群岛，CORTb与小赤麻鸭的活动、DEE和潜水持续时间不呈正相关。CORTb不能预测雏鸟的供给量，汞也不能抑制CORTb。在所有繁殖海鸟物种中，CORTb与DEE不相关。相反，与预测相反，在低纬度繁殖的物种CORTb更高。种内分析结果表明，CORTb、行为和DEE之间的关系取决于环境，这对理解CORTb在适应气候变化中的作用具有重要意义。种间分析表明，在繁殖过程中，CORTb和DEE之间不存在相关选择，而且引起CORTb变化的DEE阈值可能因物种而异。在期刊博客上免费阅读本文的通俗摘要。

Trapping trichomes, a common trait found in protogynous trap flowers, are thought to enable interaction with pollinators, promoting both pollen removal and fruit set. However, this hypothesis has yet to be empirically confirmed. In this study, we experimentally tested whether trapping trichomes favour male and female functions in trap flowers. Using protogynous South American Aristolochia esperanzae trap flowers, we observed the temporal variation in both sexual functions and associated them with the wilting of the flower and trapping trichomes. Next, we described the trapping trichomes features associated with the capture, entrapment and release of pollinators. Finally, we used manipulative experiments involving trapping trichome removal to quantify their influence on pollinator entrapment, pollen removal and fruit set. While flowers wilted after the end of the female phase, the trapping trichomes only wilted some hours after pollen presentation, promoting a delay in the exit of pollinators, so they carried pollen. Trapping trichomes features, such as a density gradient towards the interior of the tube, unidirectional orientation and epicuticular waxes, may be important in the capture and entrapment of pollinators. Trapping trichome removal decreased drastically the probability of pollinator entrapment and pollen removal, leading to no fruit set. These results indicate that the evolution and maintenance of trapping trichomes in trap flowers probably occurred through selective pressures from both sexual functions and highlight their role in the functioning of this highly phenotypically specialized pollination system.

植物竞争不仅会受到植物功能特性的影响，还会受到土壤微生物介导的适应性差异的影响。干旱等气候条件会进一步影响植物竞争。然而，人们对土壤微生物和干旱如何与具有不同根系特征的植物物种相互作用以及如何影响植物竞争结果知之甚少。我们在中国温带草原上种植了三种共生植物（Stipa krylovii、Artemisia frigida、Agropyron cristatum），将其单株或混种，并将植物组合置于五种土壤接种体（S. krylovii、A. frigida、A. cristatum 的根相关土壤、三种根区土壤的等量混合物和灭菌土壤）以及干旱处理中。这三个物种在竞争能力上表现出明显的差异，A. cristatum > S. krylovii > A. frigida，土壤接种剂或干旱处理并没有改变顺序。植株的相对产量（RY）受土壤接种物、干旱和植株排列的影响。最强的竞争者 A. cristatum 具有较高的根系总长度、根系表面积和根系体积，经历了更多的生物负反馈，而干旱加剧了这些负效应的程度。相反，最弱的竞争者 A. frigida 具有较高的比根长度，往往具有中性或积极的生物反馈，而干旱则没有影响。此外，三个物种的 RY 和适应性差异（反映为混合物中的竞争能力）受根系性状和植物-土壤反馈的影响不同。A.cristatum的RY可以通过混合物中的反馈效应预测，而适应性差异主要与根系性状有关。A. frigida（最弱的竞争者）的有效年限和适应性差异都可以通过根系性状差异和反馈效应预测。我们的研究表明，共存物种的竞争结果取决于根系性状和混合物中特定物种的 PSF 效应。未来的工作应该研究植物竞争和土壤微生物异质性如何与气候变化共同影响植物共存的机制。
