An expanded series of morphological characters developed for a cladistic analysis of extant decapods has yielded a new hypothesis for the phylogeny of the group. Application of this database to selected fossil genera produces some interesting results and demonstrates the feasibility of treating fossils as full and equal partners in the study of decapod phylogenetic relationships. In addition, it seems clear that rigorous cladistic methods can be used to evaluate the phylogenetic positions of fossils, rather than ad hoc speculation.

Contributions to Zoology solicits high-quality papers in all systematics-related branches of comparative zoology (including paleozoology). Preference will be given to manuscripts dealing with conceptual issues and to integrative papers (e.g., ecology
and biodiversity, morphology
and character state evolution, phylogeny
and historical biogeography, systematics
and bioinformatics, bioinformatics
and biodiversity, habitat disturbance
and biogeography, etc.). Reviews and alpha-taxonomic contributions are considered for publication, but acceptance will depend on their high quality and exceptional nature. Volumes 1-66 have been published under the name of

Behaviour is interested in all aspects of animal (including human) behaviour, from ecology and physiology to learning, cognition, and neuroscience. Evolutionary approaches, which concern themselves with the advantages of behaviour or capacities for the organism and its reproduction, receive much attention both at a theoretical level and as it relates to specific behaviour.
Behaviour has its roots in ethology and behavioural biology (see historical note), in which the emphasis is not so much on how animals compare with humans under strictly controlled conditions (as in comparative psychology), but more on tracing the phylogeny and evolution of natural behaviour as shown under naturalistic or natural conditions. Specialized cognition and communication are part of this approach. Well-controlled laboratory experiments are needed and welcome, but by no means the only approach.
Behaviour has a long tradition of publishing systematic observations of spontaneous behaviour.
Behaviour covers the whole animal kingdom, from invertebrates to fish, and from frogs to primates. The study of animal behaviour remains vibrant and keeps attracting young, talented scientists, who will find
Behaviour a journal with a quick turn-around time (we strive for first reviews within a month) read by a wide range of students and researchers of animal behaviour.
Behaviour was founded by Nobel Prize winner Niko Tinbergen together with W. H. Thorpe, in 1948. In a classical 1963 paper—dedicated to the 60th birthday of that other animal behaviour Nobelist, Konrad Lorenz—Tinbergen proposed that questions relating to why an animal behaves in a particular way can be viewed through four prisms. At the proximate level, we have 1) the causation of behaviour (its underlying motivation, cognition, and emotions), and 2) the behaviour's ontogeny, such as how it develops or is acquired. At the ultimate level, we have 3) the behavior's survival value, and 4) its evolution and phylogeny.
Behaviour seeks to cover all four prisms equally.

pointed, distally angular in Mesochelidura . Steinmann (1993 ) synonymized the genus back with Chelidura . Molecular phylogeny reconstruction strongly supports the monophyly of the clade and associates those species with protruding pygidia sensu Chelidurella in Verhoeff´s view.
Myriapods are the only major zoological group for which a modern encyclopedic treatment has never been produced. In particular, this was the single major gap in the largest zoological treatise of the XIX century (Grassé’s Traité de Zoologie), whose publication has recently been stopped. The two volumes of “The Myriapoda” fill that gap with an updated treatment in the English language.
Volume I opens with an introductory treatment of myriapod affinities and phylogeny. The following chapters are mostly devoted to the Chilopoda or centipedes, extensively treated from the point of view of external and internal morphology, physiology, reproduction, development, distribution, ecology, phylogeny and taxonomy. All currently recognized suprageneric and generic taxa are considered. Additional chapters deal with the two smaller myriapod classes, the Symphyla and the Pauropoda.
Volume II deals with the Diplopoda or millipedes. As in the previous volume, the treatment is articulated in chapters dealing with external and internal morphology, physiology, reproduction, development, distribution, ecology, phylogeny and taxonomy. All currently recognized suprageneric taxa and a very large selection of the genera are considered.
All groups and features are extensively illustrated by line drawings and micrographs and living specimens of representative species of the main groups are presented in color photographs.
, Ecphyadophorinae and Tylodorinae. On the other hand, De Ley and Blaxter (2002), using molecular data to revise Nematoda phylogeny, did not recognise lower taxonomic levels under Tylenchidae ( sensu De Ley & Blaxter, 2002). This omission underscores the need for further molecular studies to resolve relationships
The “Baeturia and related genera complex”, as defined earlier (De Boer, 1990) by shared aedeagal characters, is identified as the tribe Chlorocystini (sensu stricto). The Prasiini (sensu stricto) are identified as the sister group of the Chlorocystini (sensu stricto), while the genus Muda is recognized as the nearest outgroup. The phylogeny and biogeography of the sister group and outgroup is briefly discussed. Baeturia kuroiwae Matsumura is transferred to the genus Muda. A phylogenetic reconstruction of all 147 species of the Chlorocystini (sensu stricto) is presented, based on 154 characters and 409 character states. The computer program PAUP 3.1.1 (Swofford, 1993) was used for analysing the data; the genera Prasia and Muda were used as outgroups in this analysis. The results obtained from the computer analysis were slightly modified a posteriori, favouring some presumably phylogenetically important characters over strongly fluctuating ones. These final modifications were carried out with the aid of the computer program MacClade 3.0 (Maddison & Maddison, 1992). A complete data matrix and a list of characters and character states are given in an appendix; for descriptions and illustrations of these characters one is referred to previous publications.
This paper addresses the use of eye structure and optics in the construction of crustacean phylogenies and presents an hypothesis for the evolution of superposition eyes in the Decapoda, based on the distribution of eye types in extant decapod families. It is suggested that reflecting superposition optics are symplesiomorphic for the Decapoda, having evolved only once, probably in the Devonian. Subsequent loss of reflecting superposition optics has occurred following the adoption of a new habitat (e.g. Aristeidae, Aeglidae) or by progenetic paedomorphosis (Paguroidea, Eubrachyura).
