This tree diagram shows the relationships between several groups of organisms.

The root of the current tree connects the organisms featured in this tree to their containing group and the rest of the Tree of Life. The basal branching point in the tree represents the ancestor of the other groups in the tree. This ancestor diversified over time into several descendent subgroups, which are represented as internal nodes and terminal taxa to the right.

Containing group: Sericostomatoidea

Introduction

This small family, established by Wallengren (1891), is comprised of 7 genera and about 50 species. It reaches its greatest diversity in the western Palearctic region, where 5 genera occur (Beraea Stephens, Beraeamyia Mosely, Ernodes Wallengren, Beraeodes Eaton, and Beraeodina Mosely, the latter 2 monotypic). The genus Beraea also occurs in eastern North America, where 3 species are known. A single genus, Notoernodes, with 2 species, occurs in Tanzania. Elsewhere the family is found only in Japan, where it is represented by the genus, Nippoberaea Botosaneanu, Nozaki, & Kagaya, containing a single species, N. gracilis (Nozaki & Kagaya). Gut contents of Beraea gorteba Ross in southeastern North America included small pieces of vascular plants, fungal mycelia, and other organic material, but no animal parts (Hamilton 1985), foodstuffs probably typical of most species in the family. From Holzenthal et al. (2007).

Characteristics

Most beraeid larvae build slightly to strongly tapered cases of small sand grains and live in springs, seeps, and small streams, usually among aquatic mosses, leaf litter deposits, roots of emergent plants, and other dense, marginal vegetation or in the marginal organic sediments (Hamilton 1985). From Holzenthal et al. (2007).

This page is a Tree of Life Branch Page.

Each ToL branch page provides a synopsis of the characteristics of a group of organisms representing a branch of the Tree of Life. The major distinction between a branch and a leaf of the Tree of Life is that each branch can be further subdivided into descendent branches, that is, subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
