0083731KerfootThe "paradox of the plankton" was postulated in 1961 to emphasize how little we understand about the factors which promote great plankton diversity in apparently featureless pelagic regions. In 1982, the supply ratio hypothesis was presented and served as an important contribution for understanding how species could coexist on limiting nutrients. Recent modeling and experimental results suggest that very short time scale fluctuations, either caused by external forcing factors (nutrient pulses) or internal oscillations (chaos) inherent in nutrient-competition or predator-prey dynamics, may greatly increase diversity at the base of food webs. A series of interdisciplinary workshops and a symposium will gather researchers to examine how temporal and spatial patchiness interacts with food-web oscillations to promote diversity.

“浮游生物悖论”是在1961年提出的，目的是强调我们对促进浮游生物多样性的因素知之甚少。1982年，供应比假说被提出，并为理解物种如何在限制营养条件下共存做出了重要贡献。最近的模型和实验结果表明，由外部强迫因素(营养脉冲)或营养竞争或捕食者-猎物动力学固有的内部振荡(混沌)引起的极短时间尺度波动可能会极大地增加食物网底部的多样性。一系列跨学科研讨会和专题讨论会将召集研究人员研究时间和空间斑块如何与食物网振荡相互作用以促进多样性。
