Aquatic Dicotyledons of North America
Author: Donald H. Les
Publisher: CRC Press
ISBN: 1351644408
Category : Nature
Languages : en
Pages : 3174
Book Description
Aquatic Dicotyledons of North America: Ecology, Life History, and Systematics brings together a wealth of information on the natural history, ecology, and systematics of North American aquatic plants. Most books on aquatic plants have a taxonomic focus and are intended primarily for identification. Instead, this book provides a comprehensive overview of the biology of major aquatic species by compiling information from numerous sources that lie scattered among the primary literature, herbarium databases, and other reference materials. Included dicotyledon species are those having an obligate (OBL) wetland status, a designation used in the USACE National Wetland Plant List. Recent phylogenetic analyses are incorporated and rationale is provided for interpreting this information with respect to species relationships. This diverse assemblage of information will be useful to a wide range of interests including academic researchers, wildlife managers, students, and virtually anyone interested in the natural history of aquatic and wetland plants. Although focusing specifically on North America, the cosmopolitan distribution of many aquatic plants should make this an attractive text to people working virtually anywhere outside of the region as well. This book is an essential resource for assisting with wetland delineation.

The oil-collecting bees of Centris (Paracentris) (Hymenoptera: Apidae)
Author: Felipe Vivallo
Publisher: Felipe Vivallo
ISBN: 6500491785
Category : Science
Languages : en
Pages : 379
Book Description
Centris (Paracentris) Cameron is one of the most specious and morphologically diverse subgenera of the bee genus Centris Fabricius. These two features, along with the lack of modern taxonomic revisions make this group one of the lineages with the greatest taxonomic problems within Centridini. Partial revisions of groups of species from North and South America have been published, but none comprehensively studying all species described. In this book are studied all species of Centris (Paracentris) for the first time, providing diagnoses and redescriptions of both sexes. The following twenty one species are described as new: C. aenigmatica sp. nov., C. agyniax sp. nov., C. areequipensis sp. nov., C. aymara sp. nov., C. bagualis sp. nov., C. caribensis sp. nov., C. comonoxa sp. nov., C. diaguita sp. nov., C. euctenoda sp. nov., C. hexirrhina sp. nov., C. inca sp. nov., C. mexicanaides sp. nov., C. milluni sp. nov., C. multistriata sp. nov., C. niveiceps sp. nov., C. rasmusseni sp. nov., C. rozeni sp. nov., C. sacsayhuaman sp. nov., C. tayabamba sp. nov., C. xenopoda sp. nov., and C. yawar sp. nov., mainly from the South American Andes, including the first species recorded from the Caribbean. Centris satana Snelling is proposed as new junior synonym of C. laevibullata Snelling. In addition, the male of C. cisnerosi (Cockerell) and the female of C. euphenax Cockrell are described for the first time. An identification key, figures, maps, new distribution records, floral hosts, and an updated catalog for all species of the subgenus are also provided.

Sunflowers
Author: Stephen A. Harris
Publisher: Reaktion Books
ISBN: 1780239661
Category : Nature
Languages : en
Pages : 201
Book Description
From iconic paintings by Vincent van Gogh to their much-spat seeds at baseball games, the massive, golden blossoms of sunflowers have become a part of our literary and visual cultures and daily lives, inspiring artists and poets and used by advertisers to promote countless products. But sunflowers are only the most recognizable members of the world’s largest family of plants, Asteraceae, which includes lettuce, chrysanthemums, asters, dahlias, and weeds. And in this book, Stephen A. Harris unearths the extraordinary history of this entire sunflower bouquet. Unraveling the interplay between human cultures and the biology of these spectacular blooms over the last six thousand years, Sunflowers explores our persistent fascination with this family and how our uses of the plants have changed over millennia. Found in almost all habitats, from the driest deserts and tallest mountains to grasslands and urban wastelands, the sunflower family includes more than 32,000 species. It produces hugely popular and economically valuable ornamental flowers, as well as familiar flavorings such as tarragon and artemesia, and its members are also used in the production of antimalarial drugs, artificial sweeteners, insecticide, and fish poisons. Illustrated with many rarely seen images of the sunflower family, this beautiful volume sheds surprising new light on these familiar, sunniest of flowers.
