This project will address functional morphological aspects of sponge aquiferous systems in an integrative and comparative approach. Sponge leucon-type canal systems show a higher complexity of architectural patterns than previously assumed. In this context the present model of flow in sponges is regarded to be to simplified. As sponges are sessile filter feeding organisms all major physiological processes are dependent of the water processed within the canal system. Most of these processes are diffusion limited (e.g. oxygen transport). Therefore, a interdependence of specific canal system architectural patterns and growth form in sponges is expected. By means of analyzing morphometric parameters, the interdependence of canal system architecture and sponge growth form will be studied. In combining morphological data, experimentally determined flow velocity data and computational fluid dynamic results, the present theoretical standard model of flow in sponges will be refined and expanded to fit our deeper knowledge on the higher complexity of canal system architectures. Following a modeling approach the project will bring forth information on the distribution of nutrients and gas in sponges. The overall resulting expanded knowledge on sponge canal system functional morphology will lead to a deeper understanding of sponge physiology in general and thus support still ongoing efforts to establish sponge cultivation methods which are an important prerequisite for marine biotechnology and applied natural product research on sponges.

本项目将以综合和比较的方法探讨海绵含水系统的功能形态方面。海绵隐孢子虫型运河系统显示出比以前假设的更高的建筑模式的复杂性。在这种情况下，目前的海绵流动模型被认为是简化的。由于海绵是固着滤食生物，所有主要的生理过程都依赖于运河系统内处理的水。这些过程中的大多数都是扩散限制的（例如氧运输）。因此，预计海绵中特定的运河系统结构模式和生长形式的相互依赖性。通过对形态参数的分析，研究了海绵生长形态与渠系结构的相互关系。在结合形态学数据，实验确定的流速数据和计算流体动力学结果，目前的理论标准模型的海绵流量将被细化和扩展，以适应我们更深入的了解更高的复杂性运河系统架构。该项目将采用建模方法，提供海绵中营养物质和气体分布的信息。由此产生的关于海绵管道系统功能形态学的全面扩展知识将导致更深入地了解海绵生理学，从而支持仍在进行的建立海绵养殖方法的努力，这是海洋生物技术和海绵应用天然产品研究的重要先决条件。
