生活在季节性环境中的生物体在其生命周期中从一个生命阶段过渡到下一个生命阶段时暴露于不同的环境条件。不同的生命阶段如何对这些不同的条件作出反应,以及不同生命阶段之间的联系程度,是有机体生态学的基本组成部分。然而,非生物和生物因素对生物生命周期不同部分的影响往往没有被考虑在内,这限制了我们对环境变化的生态后果的理解。我们调查了气候条件、食物供应和7种野生熊蜂物种组合中先前生命阶段丰度的相对重要性,并提出以下问题:这三个因素是如何直接影响到生命各个阶段的丰度的?为此,我们使用了一个为期7年的数据集,在美国科罗拉多落基山脉的一个季节性很强的亚高山生态系统中,我们监测了气候条件、花卉资源和蜜蜂在每个生命阶段的丰度。蜜蜂在不同生命阶段的丰度对非生物和生物条件的反应在7个物种中大致一致:生命周期的生存和补充阶段(越冬蜂王)对较长的冬季呈负相关;生长阶段(工蜂)对花卉资源的可用性呈正相关;生殖阶段(雄蜂)与前一生命阶段(工蜂)的丰度呈正相关。大多数物种也表现出一些特异性反应。我们对一年生熊蜂的长期研究揭示了每个生命阶段对气候条件、花卉资源可用性和先前生命阶段的丰富度的一般反应。在不同物种中,这三个因素都直接影响不同的生命阶段,说明它们的相对重要性如何在整个生命周期中发生变化。我们采用的生命周期方法强调,如果不考虑生命阶段的具体反应,人口统计学的重要细节可能会被忽视。最终,正是这些特定于生命阶段的反应塑造了种群的结果,不仅对于动物传粉者,而且对于生活在季节性环境中的许多生物体。
Organisms living in seasonal environments are exposed to different environmental conditions as they transition from one life stage to the next across their life cycle. How different life stages respond to these varying conditions, and the extent to which different life stages are linked, are fundamental components of the ecology of an organism. Nevertheless, the influence of abiotic and biotic factors on different parts of an organism's life cycle is often not accounted for, which limits our understanding of the ecological consequences of environmental change.We investigated the relative importance of climate conditions, food availability, and previous life‐stage abundance in an assemblage of seven wild bumble bee species, asking: how do these three factors directly influence bee abundance at each life stage? To do so, we used a 7‐year dataset where we monitored climate conditions, floral resources, and abundances of bees in each life stage across the active colony life cycle in a highly seasonal subalpine ecosystem in the Colorado Rocky Mountains, USA.Bee abundance at different life stages responded to abiotic and biotic conditions in a broadly consistent manner across the seven species: the survival and recruitment stage of the life cycle (overwintered queens) responded negatively to longer winters; the growth stage (workers) responded positively to floral resource availability; and the reproductive stage (males) was positively related to the abundance of the previous life stage (workers). Most species also exhibited some idiosyncratic responses.Our long‐term examination of annual bumble bees reveals a general set of responses in the abundance of each life stage to climate conditions, floral resource availability, and previous life stage. Across species, these three factors each directly influenced a distinct life stage, illustrating how their relative importance can shift throughout the life cycle. The life‐cycle approach that we have taken highlights that important details about demography can be overlooked without considering life‐stage‐specific responses. Ultimately, it is these life‐stage‐specific responses that shape population outcomes, not only for animal pollinators but also for many organisms living in seasonal environments.
