In Advances in Entomopathogenic Nematode Taxonomy and Phylogeny the numerous species of Steinernema and Heterorhabditis described since the previous volume, published in 2007, are evaluated and discussed. Valid species proposed from 2007-2015 are covered in detail, each taxon having an illustrated diagnostic description and additional data on molecular characterisation, distribution and biology, etc. An addendum gives brief details of species proposed during 2016. An overview of the taxonomy of the two families provides an up-to-date list of species for both genera, including new synonyms and detailed commentary on specific status where appropriate. Tabular keys to all valid species of Steinernema and Heterorhabditis assist in diagnostics. A chapter on phylogeny and phylogeography completes the book.

Pristionchus pacificus

A Nematode Model for Comparative and Evolutionary Biology

Series:

Edited by Ralf J. Sommer

This edited volume on the nematode model Pristionchus pacificus describes an integrative approach to evolutionary biology. It aims for a merger of evolutionary and comparative biology with mechanistic approaches based on genetics and molecular biology.
Insight into the function of biological systems obtained from laboratory studies when complemented with ecology, natural variation and natural history of an organism, can provide detailed knowledge of the proximate and ultimate causations of species.
Ralf J. Sommer developed P. pacificus as model system for integrative evolutionary biology with case studies in evo-devo and population genetics on La Réunion Island. Similarly, ecological interactions with scarab beetles revealed examples for the evolution of novelty at the morphological and behavioural level and their underlying molecular mechanisms.

Contributors include Paul W. Sternberg, Ralf J. Sommer, Jagan Srinivasan, Christian Rödelsperger, Frank C. Schroeder, Robin M. Giblin-Davis,
Natsumi Kanzaki, Matthias Herrmann, Angela McGaughran, Katy Morgan, Akira Ogawa, Federico D. Brown, Ray E. Hong, Robbie Rae,

The sheath nematodes belonging to the superfamily Hemicycliophoroidea are unique amongst all plant parasitic nematodes known to man due to the presence of an extra cuticular covering or sheath over the inner cuticle and body of all juvenile and adult life stages. These plant-parasitic nematodes include species of agricultural and quarantine importance.
In Systematics of the Sheath Nematodes of the Superfamily Hemicycliophoroidea John Chitambar and Sergei Subbotin provide a detailed review of the taxonomy and diagnosis of the superfamily, its member genera and 153 related species based on their morphological and molecular analyses, as well as a further understanding of the relationships within the superfamily using molecular phylogenetics. In addition, Chitambar and Subbotin also give detailed information on the global distribution, biology, host-parasite relationships and ecology of sheath nematodes.

The Evolutionary History of Nematodes

As revealed in stone, amber and mummies

Series:

George O. Poinar Jr.

Nematodes are one of the most abundant groups of invertebrates on the face of the earth. Their numbers are estimated to range from 1000 per cm2 in the sand-covered hydrogen sulphide ‘black zone’ beneath the ocean floors to 1.2 billion in a single hectare of soil. Estimates for their species diversity range from 100 000 to 10 million. The past history of nematodes is a mystery, since very few fossils have been discovered. This book establishes a solid base in palaeonematology with descriptions of 66 new fossil species and accounts of all previous fossil and subfossil nematodes from sedimentary deposits, coprolites, amber and mummies. It shows how nematode fossils can be used to establish lineages at various locations and time periods in the earth’s history and when nematodes entered into symbiotic and parasitic associations with plants and animals.

Volume 8 in the series, appearing in two parts, A and B, deals with the systematics of cyst nematodes of the subfamily Heteroderinae. Cyst nematodes are important pathogens causing extensive damage and significant yield loss to many crops in both temperate and tropical regions. Part A presents summarised information on various aspects of morphology, biology, ecology, pathology, biogeography, control measures and diagnostics of these nematodes. Molecular diagnostic tables and comprehensive tabular and dichotomous keys for species identification, together with descriptions of protocols for extraction, light and electron microscopy studies, and molecular diagnostics are also included. The taxonomic section of part A provides diagnoses for six genera, viz., Globodera, Punctodera, Cactodera, Dolichodera, Betulodera and Paradolichodera, and includes descriptions and morphometrics of 30 valid species. The work is illustrated by 101 drawings and photos. The genus Heterodera is mainly covered in part B, complete descriptions and morphometrics of the 80 known valid species being provided and the species illustrated by 159 line drawings and photos. Identification of the species using morphological and molecular techniques is also covered. Each part includes an extensive bibliography.

This is the first and so far the one and only treatise on the morphology of the Tylenchs. Tylenchs are economically important Nematodes that live in huge numbers in the soil. They are microscopic and they show a constant number of cells, a characteristic in Nematodes. The cell count in Tylenchs, undertaken here for the first time, resulted in an estimate of fewer than a thousand cells. All the different cell types are described in great detail, and some of them are rather unusual in the Animal Kingdom. The internal pressure system (typical for Nematodes) in conjunction with the presence of a hollow stylet (typical for Tylenchs), results in rigorous but functional relations among the several body parts. Throughout the book functional morphology is a key topic and an entire chapter is devoted to it. The book is amply illustrated with line drawings that are based on microscopic and sub-microscopic observations.
