我们利用系统动力学模型来描述由光照和养分供应控制的藻类生长和由作物丰度和营养质量控制的浮游动物生长,探索最小化浮游动物害虫对商业微藻作物影响的方法。当微藻作物生长最快时,它们的损失最小,相反,当它们在养分枯竭的条件下生长缓慢时,损失也最小。然而,在许多培养系统中,由于密集悬浮液的自遮光而减少的光利用率有利于在营养充足的情况下缓慢生长。这种情况提高了作为猎物的微藻的质量,促进了浮游动物的生长,并导致作物迅速歉收。害虫进入的时机很重要;在为高碳含量(例如用于生物燃料)种植的已建立的、营养枯竭的微藻群落中,作物损失的可能性最小。一个潜在的有用方法是促进低水平的磷胁迫,这不会对微藻的生长产生不利影响,但会产生对浮游动物生长不理想的作物。本文的在线版本(doi:10.1007/s10811-017-1112-8)包含补充资料,仅供授权用户使用。
We explore approaches to minimise impacts of zooplanktonic pests upon commercial microalgal crops using system dynamics models to describe algal growth controlled by light and nutrient availability and zooplankton growth controlled by crop abundance and nutritional quality. Losses of microalgal crops are minimised when their growth is fastest and, in contrast, also when growing slowly under conditions of nutrient exhaustion. In many culture systems, however, dwindling light availability due to self-shading in dense suspensions favours slow growth under nutrient sufficiency. Such a situation improves microalgal quality as prey, enhancing zooplankton growth, and leads to rapid crop collapse. Timing of pest entry is important; crop losses are least likely in established, nutrient-exhausted microalgal communities grown for high C-content (e.g. for biofuels). A potentially useful approach is to promote a low level of P-stress that does not adversely affect microalgal growth but which produces a crop that is suboptimal for zooplankton growth.
