人类(渔业)初级生产和消费的全球分布是有据可查的，但我们没有将食物网内消费的中心生态过程与温度和其他生态驱动因素联系起来的地图。使用横跨四大洲105°纬度的标准化分析，我们表明浅海生态系统中通用性捕食者的诱饵消耗率与温度和消费者群体的组成密切相关。出乎意料的是，在北半球和南半球的海草和非植物沉积物生境中，消耗率都在中纬度(25°至35°)达到峰值。这种模式与陆地系统形成对比，据报道，陆地系统中的生物相互作用在远离赤道的地方减弱，但它与海洋生物多样性中正在出现的亚热带高峰模式相平行。中纬度地区的高消费与现有消费者的类型密切相关，这更好地解释了消费率高于消费者密度、生物量、物种多样性或栖息地。事实上，温度对消费的明显影响主要是由消费者群体组成中与温度相关的周转推动的。我们的发现加强了气候变暖对物种组成变化的关键影响，并强调了它对地球生态系统功能的影响。
The global distribution of primary production and consumption by humans (fisheries) is well-documented, but we have no map linking the central ecological process of consumption within food webs to temperature and other ecological drivers. Using standardized assays that span 105° of latitude on four continents, we show that rates of bait consumption by generalist predators in shallow marine ecosystems are tightly linked to both temperature and the composition of consumer assemblages. Unexpectedly, rates of consumption peaked at midlatitudes (25 to 35°) in both Northern and Southern Hemispheres across both seagrass and unvegetated sediment habitats. This pattern contrasts with terrestrial systems, where biotic interactions reportedly weaken away from the equator, but it parallels an emerging pattern of a subtropical peak in marine biodiversity. The higher consumption at midlatitudes was closely related to the type of consumers present, which explained rates of consumption better than consumer density, biomass, species diversity, or habitat. Indeed, the apparent effect of temperature on consumption was mostly driven by temperature-associated turnover in consumer community composition. Our findings reinforce the key influence of climate warming on altered species composition and highlight its implications for the functioning of Earth’s ecosystems.
