Molecular systematics provides increasing evidence for the backbone topology of what we call the New Heterobranchia tree. This radically reorganizes roughly 40,000 morphologically and ecologically diverse species, including opisthobranch and pulmonate snails and slugs. However, exact relationships, anatomy and evolution of many major traditional clades,, especially of lower heterobranchs, remained unresolved. In the first period of the present project we have examined representatives of most major heterobranch lineages, adding detailed microanatomical information from serial semithin histological sections of entire individuals. We have also provided multi-locus data and first hypotheses on the origin and evolution of several of the most enigmatic and aberrant major heterobranch clades, such as Rhodopemorpha, Murchisonellidae, Ringiculidae, and some Acteonoidea-related groups. In the prolongation period applied for herein we want to 1) take the chance and examine in 3D microanatomical detail unique material of minute, extremely elusive representatives of Cimidae, Graphidae and Tjaernoeeidae, the last 3 lower heterobranch families without any microanatomical knowledge. In particular, we want to 2) complete our multi-locus data sets, perform state of the art phylogenetic analyses, and reconstruct the evolution of heterobranchs comprehensively. Integrating molecular and morphological evidences will allow for re-evaluating homology and function of organs and their evolution across heterobranchs, leading to a new understanding of this large and important group.

分子系统学提供了越来越多的证据，证明了我们所说的新异叉树的主干拓扑结构。这从根本上重组了大约40,000个形态和生态上不同的物种，包括脊椎动物和肺类蜗牛和鼻涕。然而，许多主要的传统支系，特别是较低的杂枝分支的确切关系、解剖和进化仍未解决。在本项目的第一阶段，我们研究了大多数主要异枝血统的代表，添加了来自整个个体的连续半薄组织切片的详细显微解剖信息。我们还提供了几个最神秘和最异常的主要杂枝分支的起源和进化的多基因座数据和第一个假设，如红形目、小蜂科、环形科和一些与Acteonoidae相关的类群。在本文申请的延长期内，我们想要1)抓住机会，在没有任何显微解剖知识的情况下，对后三个低等异种科的独特材料进行微小的、极其难以捉摸的代表的研究。特别是，我们希望2)完成我们的多基因座数据集，进行最先进的系统发育分析，并全面重建异种分支的进化。结合分子和形态证据将允许重新评估器官的同源性和功能及其跨异分支的进化，导致对这一庞大而重要的群体的新理解。
