A Phylogenetic Approach to the Neotropical Social Wasp Genus Leipomeles Möbius, 1856 (Vespidae: Epiponini), with a New Identification Key


Book Description

Leipomeles Möbius, 1856, is a neotropical genus of swarm-founding wasps extending from Costa Rica to the middle of Brazil, with four species described. A combined phylogenetic analysis using female and male morphology, and nest architecture was performed with the program TNT. Leipomeles is supported as monophyletic with the following relationships among species: (L. pusilla + L. albogrisea) + (L. spilogaster + L. dorsata). A new identification key for the genus is also presented.







Total-evidence Phylogeny of the New World Polistes Lepeletier, 1836, Paper Wasps (Vespidae, Polistinae, Polistini)


Book Description

The genus Polistes is one of the most species-rich and widely distributed groups of social wasps and a model taxon for studies of social behavior. Almost half the Polistes world fauna occurs in the New World, but their classification has been unstable due in part to the scarcity of phylogenetic studies. We investigated the phylogeny of the New World Polistes by combining a previously existing molecular dataset with a new morphological and behavioral matrix for 90 of the 93 New World species. All analyses support a single origin for the New World Polistes. All five traditionally defined New World subgenera (Aphanilopterus, Epicnemius, Fuscopolistes, Onerarius, and Palisotius) were monophyletic, but the relationships among them varied across datasets. Our results, with an expanded phenotypic dataset, improved taxonomic sampling, and enhanced clade support relative to previous studies, strongly support a classification based on five subgenera, which are all diagnosable groups supported by clear morphological synapomorphies. Hence, we propose the revalidation of previously proposed subgenera; we provide a taxonomic account of each subgenus and an identification key to all species of New World Polistes.







The Phylogeny of the Species of the Genus Agelaia Lepeletier, 1836, One of the Basalmost Groups of Epiponini, with Notes on Male Genitalia (Hymenoptera: Vespidae; Polistinae)


Book Description

A cladistic analysis of the species of the Neotropical social wasp genus Agelaia Lepeletier, 1836, was performed employing female morphology and nest architecture data. Analysis resulted in a single cladogram with length 339, consistency index 0.22, and retention index 0.60, supporting Agelaia as monophyletic. Agelaia bequaerti and A. anceps are raised to specific rank. Male genitalia of A. angulata, A. areata, A. cajennensis, A. centralis, A. flavipennis, A. fulvofasciata, A. multipicta, A. ornata, A. pallipes, A. panamaenis, A. testacea, A. timida, A. vicina, and A. yepocapa are depicted and described, including comparative remarks. A revised identification key is provided.




Tyrannosaurid Paleobiology


Book Description

Drawn from a 2005 international symposium, these essays explore current tyrannosaurid current research and discoveries regarding Tyrannosaurus rex. The opening of an exhibit focused on “Jane,” a beautifully preserved tyrannosaur collected by the Burpee Museum of Natural History, was the occasion for an international symposium on tyrannosaur paleobiology. This volume, drawn from the symposium, includes studies of the tyrannosaurids Chingkankousaurus fragilis and “Sir William” and the generic status of Nanotyrannus; theropod teeth, pedal proportions, brain size, and craniocervical function; soft tissue reconstruction, including that of “Jane”; paleopathology and tyrannosaurid claws; dating the “Jane” site; and tyrannosaur feeding and hunting strategies. Tyrannosaurid Paleobiology highlights the far ranging and vital state of current tyrannosaurid dinosaur research and discovery. “Despite being discovered over 100 years ago, Tyrannosaurus rex and its kin still inspire researchers to ask fundamental questions about what the best known dinosaur was like as a living, breathing animal. Tyrannosaurid Paleobiology present a series of wide-ranging and innovative studies that cover diverse topics such as how tyrannosaurs attacked and dismembered prey, the shapes and sizes of feet and brains, and what sorts of injuries individuals sustained and lived with. There are also examinations of the diversity of tyrannosaurs, determinations of exactly when different kinds lived and died, and what goes into making a museum exhibit featuring tyrannosaurs. This volume clearly shows that there is much more to the study of dinosaurs than just digging up and cataloguing old bones.” —Donald M. Henderson, Royal Tyrrell Museum of Palaeontology




Handbook of Agricultural Entomology


Book Description

Handbook of Agricultural Entomology by Helmut van Emden is a landmark publication for students and practitioners of entomology applied to agriculture and horticulture. It can be used as a reference and as a general textbook. The book opens with a general introduction to entomology and includes coverage of the major insects (and mites) that cause harm to crops, livestock and humans. The important beneficial species are also included. Organisms are described in a classification of insect Orders and Families. The emphasis is on morphological characters of major taxonomic divisions, “spot characters” for the recognition of Families, and the life histories, damage symptoms and economic importance of the various pest species. The book is beautifully illustrated in full colour with more than 400 figures showing both the organisms and the damage caused to plants with diagnostic characters indicated by arrows. Coverage is world-wide and includes much material stemming from the vast personal experience of the author. A companion website with additional resources is available at www.wiley.com/go/vanemden/agriculturalentomology




Phylogenetics and Ecology


Book Description

The relationship between systematics and ecology has recently been invigorated, and developed a long way from the "old" field of comparative biology. This change has been two-fold. Advances in phylogenetic research have allowed explicit phylogenetic hypotheses to be constructed for a range of different groups of organisms, and ecologists are now more aware that organism traits are influenced by the interaction of past and present. This volume discusses the impact of these modern phylogenetic methods on ecology, especially those using comparative methods. Although unification of these areas has proved difficult, a number of conclusions can be drawn from the text. These include the need for a "working" bridge between evolutionary biologists using logic-based cladistic methods and those using probability-based statistical methods, for care in the selection of tree types for comparative studies and for systematists to attempt to analyse ecologically important groups. Comparative ecologists and systematists need to come together to develop these ideas further, but this volume presents a very useful starting point for all those interested in systematics and ecology.







Natural History and Evolution of Paper-wasps


Book Description

The diversity of social behaviour among birds and primates is surpassed only by members of the Hymenopteran insects (bees, ants, and wasps). The paper-wasps are a large and varied group, and have been studied extensively by a wide range of biologists interested in the evolution of sociality. This book is unusual in combining synthetic reviews and new, unpublished data with original ideas.
