动物聚集在生境斑块上可以产生营养“热点”，促进生物地球化学循环和初级生产，但这种热点在连续珊瑚礁生境中出现的条件尚不清楚。本研究旨在确定不同规模的珊瑚礁结构复杂性如何调节鱼类来源的营养供应和相关的底栖生物富集。我们在美国佛罗里达群岛的六个珊瑚礁景观（每个约2500平方米）进行了鱼类调查和高分辨率摄影测量。在25 m2尺度上，我们利用矢量崎岖度（VRM）量化了大尺度垂直起伏和精细尺度复杂性，利用鱼类生物能量学模型估算了氮(N)和磷(P)供应，并测量了大藻组织%N和%P。我们发现，鱼类来源的营养供应随着珊瑚礁垂直起伏的增加而增加，超过2.8 m，供应率达到饱和。VRM与养分供应呈正相关，特别是在低洼地区，表明规模依赖效应。大藻养分含量与供给量呈非线性关系，吸收稳定在~250 mg N - m-2 d -1和~35 mg P - m-2 d -1以上。非线性模式是由高起伏热点驱动的，那里的营养供应是周围珊瑚礁的几倍。这些发现表明，中尺度栖息地的复杂性在不同尺度上相互作用，形成消费者驱动的营养供应和底栖生物的丰富。确定救济和VRM的阈值为养分热点何时何地形成提供了新的见解，并为针对最有可能提高生产力的珊瑚礁特征进行修复提供了实用指导。

Research Highlight: MacLeod, K., Bouffet-Halle, A., Wapstra, E., Uller, T., While, G. (2025). Maternal glucocorticoids have persistent effects on offspring social phenotype irrespective of opportunity for social buffering. Journal of Animal Ecology, https://doi.org/10.1111/1365-2656.70121. Maternal effects can have wide-ranging effects on offspring phenotypes. Understanding if there are ways to ameliorate negative effects of poor early lives including maternal stress is a critical outstanding question. For example, the social buffering hypothesis predicts that individuals can reduce the negative effects of poor early lives with positive later life social environments. MacLeod et al. (2025) tested this hypothesis in a facultatively social lizard, Liopholis whitii, with a full-sibling split brood breeding design. They found evidence for social buffering of postnatal activity, but not for size, growth or social interactions. Instead, prenatal glucocorticoid exposure is a strong predictor of increased social interactions as well as decreased size and growth. Their results suggest that for many phenotypes, a poor early start can lead to lifelong effects, but for others, positive social environments could ameliorate negative early lives. Future work is needed to build a framework to predict which phenotypes have propensities for longer term social buffering to assess agents of selection and pathways for interventions.
研究亮点：MacLeod， K., Bouffet-Halle， A., Wapstra， E., Uller， T., While， G.（2025）。母亲的糖皮质激素对后代的社会表型有持续的影响，而不考虑社会缓冲的机会。动物生态学杂志，https://doi.org/10.1111/1365-2656.70121。母系效应可以对后代的表型产生广泛的影响。了解是否有办法改善早期生活不良的负面影响，包括母亲的压力，是一个关键的悬而未决的问题。例如，社会缓冲假说预测，个人可以通过积极的晚年社会环境来减少早期生活不良的负面影响。MacLeod et al.（2025）在一种兼性社会性蜥蜴Liopholis whititii中验证了这一假设，该蜥蜴采用全兄弟姐妹分离的繁殖设计。他们发现了产后活动存在社会缓冲的证据，但没有发现大小、成长或社会互动的证据。相反，产前糖皮质激素暴露是社会互动增加以及体型和生长减少的一个强有力的预测因素。他们的研究结果表明，对许多表现型来说，糟糕的早期开始可能会导致终生影响，但对其他表现型来说，积极的社会环境可以改善消极的早期生活。未来的工作需要建立一个框架来预测哪些表型具有长期社会缓冲的倾向，以评估选择因子和干预途径。
