This guide will prove useful to dedicated amateurs for achieving currency in ant taxonomy, and to specialists attempting to expand on current knowledge. This book is a must for entomologists, ecologists, and particularly all who study ants. Praise For Ants of North America: A Guide to the Genera…. Such behavior is presumably due to favorable ecological conditions at middle altitudes. Ants Formicidae: Hymenoptera are important components of forest ecosystems and can be affected by fuel reduction forest management practices.
Ants were identified to species using keys in Coovert 2005 , Fisher and Cover 2007 , and Ellison et al. The relatively colder spring temperatures in coastal areas as compared with inland corresponded with higher physiological cold tolerance in the ants, even though the coastal areas are annually warmer. Bird's Nest Ferns are distributed from east Africa across Asia and down into Australia. Decoupling of canopy and understory vegetation disturbances revealed gap formation as an important short-term driver of ground-dwelling invertebrate community structure and composition. I am now in the process of carrying out experimental invasions of the ferns by a focal species of Diacamma in order to experimentally verify the mechanisms behind the patterns observed. As a result the ferns provide an ideal habitat for a variety of arthropods and other animals.
Our results indicate that some fuel reduction treatments can alter forest ant communities, thus contributing to changing forest ecosystem dynamics. Rank trap-inci- dence curves Fig. It is a joy to browse and read, and will have an important impact on the study of ants. In tropical rain forest they grow at all heights in the canopy, up to 60m in areas where the canopy goes that high. Zoological Journal of the Linnean Society. .
A manipulative experiment was designed to decouple effects of simultaneous disturbances to the forest canopy and ground-level vegetation to understand their individual and combined impacts on ground-dwelling invertebrate communities. Adult workers pierce the integument of their larvae to imbibe haemolymph, earning them the Dracula ant. Spanning across broad altitudinal and latitudinal gradient, selected sites differed greatly for various micro-habitat variables. It is a joy to browse and read, and will have an important impact on the study of ants. Photographs of adults, lateral and ventral aedeagus, and ejaculatory pump, as well as characteristic damage by the agromyzids on host plants were presented.
Information available on species composition, richness and diversity of ant communities of Western Ghats is limited. The coastal spring temperatures also influenced ant phenology so that, in a warm year, the coastal ants began foraging considerably earlier than inland ants, likely due to their lower physiological cold tolerance. We add another 34 species based on newly collected materials, review of museum and personal collections, and online databases. It provides, for the first time, an accessible and lavishly illustrated guide to all the ant genera occurring in the United States and Canada. The fern retains the decomposing leaf litter in its mossy core, which also acts as a sponge for intercepted water.
This concise, easy-to-use, authoritative identification guide introduces the fascinating and diverse ant fauna of the United States and Canada. It features the first illustrated key to North American ant genera, discusses distribution patterns, explores ant ecology and natural history, and includes a list of all currently recognized ant species in this large region. Seit zehn Jahren steigt die Zahl der Landkonflikte in Kambodscha. It will greatly enhance both public interest in ants and scientific investigation of their ecology, behavior and evolution. These fascinating creatures often dominate the environments they inhabit--familiar to virtually everyone, but understood by very few. Because the total diversity of species within a given region γ diversity is influenced by both local diversity α diversity and dissimilarity in community composition β diversity , understanding disturbance effects on both components of diversity is essential, especially if disturbance impacts α and β diversities differently.
The most recent work before this dealing exclusively with the North American fauna was W. Review of Ants of North America A guide to the Genera. These ants mostly nest in soil and are scavengers that will also tend honey- dew-producing Hemiptera, an important food source Fisher and Cover 2007. Creighton's The Ants of North America 1950. It is a joy to browse and read, and will have an important impact on the study of ants. It features the first illustrated key to North American ant genera, discusses distribution patterns, explores ant ecology and natural history, and includes a list of all currently recognized ant species in this large region.
Formation of gaps was the primary driver of changes in invertebrate community structure, increasing activity-abundance and taxonomic richness, while understory removal had smaller effects. We want to explain how the genus colonised Madagascar from Africa and explore where the evolution of its wingless, ergatoid queen occurred. The item Ants of North America : a guide to the genera, Brian L. These impacts may have interacting effects on populations of ground-dwelling invertebrates that regulate ecological processes such as decomposition and nutrient cycling. Dates have been traced for all parts except five, and two of those may have been issued with other parts that have been dated. It will greatly enhance both public interest in ants and scientific investigation of their ecology, behavior and evolution.
It features the first illustrated key to North American ant genera, discusses distribution patterns, explores ant ecology and natural history, and includes a list of all currently recognized ant species in this large region. This concise, easy-to-use, authoritative identification guide introduces the fascinating and diverse ant fauna of the United States and Canada. Illustrated key to the North American ant genera. Each entry includes number of North American species, diagnostic remarks, distribution and ecology, plus one or two color photos with metric guide to indicate size. This makes the ferns ideal for use as microcosms for the study of ant community ecology.
Beta diversity β-diversity was lowest 19% between contiguous sites like Thattekkad Bird Sanctuary and Idukki Wildlife Sanctuary and highest between site Manalar and Periyar Tiger Reserve at 68% suggesting that ant species composition distinctly varied in these sites. We implemented treatments multiple times two mechanical thinnings and four prescribed burns over the course of a 15-yr period. Cover ; illustrated by Ginny Kirsh and Jennifer Kane ; color images created by April Nobile. Our results indicated that only few species were adapted to full spectrum of environmental variation along altitudinal gradient studied and both species richness and diversity peaked at mid-elevations as against higher elevations wherein it underwent rapid decline. A redescription and photographs of S. Melanagromyza splendida Frick 1953 boring stems of Carthamus tinctorius L.
