长期研究一直是种群生态学的支柱。红鸡Lagopus lagopus scoticus是自20世纪50年代以来在该领域做出广泛贡献的物种之一。本文回顾了这些研究的轨迹和深远的影响。红松鸡研究将标记个体的长期研究与广泛地理区域的人口统计学研究以及重复的个体和种群水平的操作相结合。主要关注的是了解红松鸡种群周期的原因,特别是内在的相对重要性。(行为)和外在(气候,食物限制和寄生虫)机制。在不同地区进行的单独研究最初提出,线虫寄生虫细毛圆线虫或秋季雄性攻击性的变化是种群周期的驱动因素。最近的实验表明,寄生虫不是周期的必要原因,强调行为和寄生虫介导的机制是相互关联的。长期实验表明寄生虫和攻击性相互作用。两个突出的问题仍有待实验验证。首先,是什么内在机制导致男性攻击性模式的时间变化?目前受欢迎的机制与亲属结构模式有关,尽管还有其他假设。第二,双重的相互作用机制如何影响种群动态?红鸡的研究对种群生态学领域产生了重要影响,特别是通过强调:(1)寄生虫对种群的影响;(2)内在机制在循环动力学中的作用;(3)需要考虑多种相互作用的机制。
Long‐term studies have been the backbone of population ecology. The red grouseLagopus lagopus scoticusis one species that has contributed widely to this field since the 1950s. This paper reviews the trajectory and profound impact that these studies have had.Red grouse research has combined long‐term studies of marked individuals with demographic studies over wide geographical areas and replicated individual‐ and population‐level manipulations.A main focus has been on understanding the causes of population cycles in red grouse, and in particular the relative importance of intrinsic (behaviour) and extrinsic (climate, food limitation and parasite) mechanisms.Separate studies conducted in different regions initially proposed either the nematode parasiteTrichostrongylus tenuisor changes in male aggressiveness in autumn as drivers of population cycles.More recent experiments suggest that parasites are not a necessary cause for cycles and have highlighted that behavioural and parasite‐mediated mechanisms are interrelated. Long‐term experiments show that parasites and aggressiveness interact.Two outstanding questions remain to be tested experimentally. First, what intrinsic mechanism causes temporal variation in patterns of male aggressiveness? The current favoured mechanism is related to patterns of kin structuring although there are alternative hypotheses. Second, how do the dual, interacting mechanisms, affect population dynamics?Red grouse studies have had an important impact on the field of population ecology, in particular through highlighting: (1) the impact of parasites on populations; (2) the role of intrinsic mechanisms in cyclic dynamics and (3) the need to consider multiple, interacting mechanisms.
