Collaborative Research: T-LEOST (realTime - Larval Environment and Ocean Signal Tracking): An Integrated System for the study of Navigational Cues in the Marine Environment

目前研究鱼类幼体航行的挑战是采样远洋环境中鱼类幼体感知到的信号。为了迎接这一挑战，皮？S计划建立新的生物声学技术和概念验证方法来现场监测幼虫的行为，开发一个集成的实时幼虫环境和海洋信号跟踪系统。几乎对幼虫在幼虫期早期、远海或夜间的取向一无所知。现在已经很清楚，行为可以在浮游幼虫的扩散中发挥关键作用，但涉及幼虫扩散的生物过程在很大程度上仍不清楚。分散的幼虫用来确定它们游泳方向(方向)的线索序列以及它们如何在空间上变化完全是推测的结果。海洋幼虫的方位是理解和模拟沿海生物中上层阶段的一个中心问题。拟议的研究将提供远洋定向之谜的重要部分，这将导致更好地了解幼虫的扩散和种群连通性，并提高对它们进行建模的能力。该项目还将作为一个观察系统平台，对于了解幼虫对全套感官信号的使用至关重要，例如偏振光、水运动的电接收以及其他(磁、热)。我们提议的系统的最大好处之一是能够为现有的海洋观测系统提供对成功招募海底物种有意义的环境信号的记录。更广泛的影响：该项目的更广泛影响在于它有可能对我们理解海洋生物扩散的潜在机制做出有意义的贡献。工作人员将制作一段教育视频，指导高中生和大学生，并在公共论坛上提供游泳幼鱼的视频。

The current challenge in the study of larval fish navigation is to sample signals as they are perceived by fish larvae in the pelagic environment. To meet this challenge, the PI?s plan to build upon novel bio-acoustic technology and proof of concept methods for monitoring larval behavior in situ, to develop an integrated realTime Larval Environment and Ocean Signal Tracking (T-LEOST) system. Almost nothing is known about the orientation of larvae earlier in the larval phase, far offshore, or at night. It is now clear that behavior can play a crucial role in pelagic larval dispersal, but the biological processes involved in larval dispersal remain largely unknown. The sequence of cues that dispersing larvae use to determine their swimming direction (orientation) and how they vary spatially is entirely subject to speculation. The orientation of marine larvae is a central issue in understanding and modeling the pelagic stage of coastal organisms. The proposed research will supply important pieces of the pelagic orientation puzzle, that will lead to a better understanding of larval dispersal and population connectivity, and an improved ability to model them. The project will also serve as an observing system platform that will be vital in understanding larval use of a full suite of sensory cues, such as polarized light, electroreception of water movement, and other (magnetic, thermal). One of the over-arching benefits of our proposed system is the capacity to provide existing ocean observing systems with recording of environmental signals meaningful to the successful recruitment of benthic species.Broader Impacts: The project's broader impact lies in its potential to contribute meaningfully to our understanding of the mechanisms underlying dispersal in marine organisms. Personnel will produce an educational video, mentor high-school and college students and provide videos of swimming larval fish in public forums.
