对爱尔兰斯莱戈郡一个小湖的沉积物剖面进行的高分辨率孢粉和地球化学分析表明，新石器时代的人类发展受到了明显的气候振荡的影响。在公元前3810年榆树衰落的同时，环湖的原始林地经历了相当大的变化。随后夏季气温的升高和降雨量的减少有利于在该湖的集水区种植小麦，这一做法已有大约140年的历史。在公元前3650年至3560年之间，随着异常干燥的条件的建立，发生了向田园农业的转变，当时湖泊水位和异地物质的流入明显较低。新石器时代早期向中期过渡时开始的凉湿条件可能导致了该地区人类活动的最初下降。新石器时代中期和晚期早期降雨量特别大的时期促成了第一批农民放弃该地区。研究地点的代理记录与爱尔兰的其他孢粉学和考古学记录的比较表明，十年至百年尺度的气候变化代表了新石器时代耕作做法的性质和持续时间的主要控制。版权所有©2012 John Wiley&Sons，Ltd.
High‐resolution pollen and geochemical analyses conducted on a sediment profile from a small lake in County Sligo, Ireland, revealed that human development during the Neolithic was influenced by pronounced climatic oscillations. The primeval woodland around the lake experienced a considerable transformation coinciding with the elm decline at 3810 BC. The subsequent increase in summer temperatures and decrease in precipitation favoured wheat cultivation in the lake's catchment area, which was practised for approximately 140 years. A shift towards pastoral farming took place with the establishment of exceptionally dry conditions between 3650 and 3560 BC, when lake level and influx of allochthonous material were notably low. The onset of cool and wet conditions at the transition from the Early to Middle Neolithic possibly caused the initial decline of human activity in the area. Periods of particularly high precipitation during the Middle and early Late Neolithic contributed to the abandonment of the area by the first farmers. Comparison of the proxy record from the study site with other palynological and archaeological records from Ireland suggests that climatic variability on the decadal to centennial scale represented a primary control on the nature and duration of farming practices during the Neolithic.
