中文摘要
Rankin 9800767之前关于环境如何影响觅食资源分配的研究依赖于研究人员正确地对有机体的行为进行分类的能力。这些研究还依赖于这样一种假设,即热量输出和时间分配提供的资源的粗略测量是限制营养分配的准确测量。通过利用陷阱合成有机体,PI可以明确地将投资归类为觅食。此外,基于我对网络营养生态的最新进展,PI现在知道,网络的一些组件限制了需要单个有机体根据其环境进行预算的基本营养。令人欣慰的是,初步结果表明,像分配有限资源这样的重要功能可能在同一种群中不同个体的雌性后代中有所不同。只有通过更广泛的测试,使用更多女性的后代,才能证明或反驳家庭x治疗相互作用的可能性。
英文摘要
Rankin 9800767 Previous research into how environment influences resource allocation to foraging rely on the ability of the researcher to correctly classify an organism's behavior. These studies also rely on the assumption that rough measures of resources provided by caloric output and time allocation are accurate measures of allocation of limiting nutrients. By utilizing a trap-synthesizing organism, the PI can unambiguously classify the investment into foraging. Furthermore, based upon recent advances in my understanding of the nutritional ecology of the web, the PI now knows that some components of the web are limiting essential nutrients requiring budgeting by the individual organism in response to its environment. It is tantilizing that preliminary results indicate that such a vital function as allocation of a limiting resource might vary among the offpring of different individual females from a single population. Only by a more extensive test, using the offspring of many more females, can the possibility of a family x treatment interaction be proven or disproven.
