The World of the Tent-Makers/ A natural history of the eastern tent caterpillar. V. G. Dethier. University of Massachusetts Press, Amherst, MA 01002. 1980. 148 pages, 5,95 (paper).
(excerpt)
This book is small in size, but large in stature, a simply eloquent narrative on the encounters of genes; a look at the problems and solutions evolved by the eastern tent caterpillar in getting from one year to the next
Public investments in Croatia
This Occasional Paper occurred as the byproduct of preparations for writing the report by Geoff Dixon, Katarina Ott and Jean-Jacques Dethier “Capital Expenditure by the Government in Croatia: Fiscal Accounts, Budgetary Institutions and Budgeting Process”, The World Bank, Europe and Central Asia Region, Poverty Reduction and Economic Management Unit, June 1998. The authors, Katarina Ott and Anto Bajo (Institute of Public Finance) first published the text in Croatian in the Institute’s journal “Financijska praksa” Volume 23, Number 1, (March 1999). This Occasional Paper is the English language translation of the article published in “Financijska praksa”
Notes on Shifting Distribution Patterns and Survival of Immature \u3ci\u3eDanaus Plexippus\u3c/i\u3e (Lepidoptera: Danaidae) on the Food Plant \u3ci\u3eAsclepias Syriaca\u3c/i\u3e
Abundance and distribution of immature stages of the monarch butterfly, Danaus plexippus, on the food plant Asclepias syriaca were examined at a site in southeastern Wisconsin over one growing season. Estimated mortality for eggs and larvae was substantial (88%). Dispersal of larvae between individual food plants, along with egg and larval mortality factors, may result in low population density. Although the mechanism triggering larval dispersal is unknown, several alternative hypotheses are proposed for further examination
The Comparative Ethology and Evolution of the Sand Wasps. Howard E. Evans. Cambridge: Harvard University Press, 1966. xviii, 526 pp. $15.00.
Excerpt: In one sense, ethology is natural history. In a more restricted sense, it is the description and classification of behavior viewed as a necessary prerequisite to analysis. The analyses that follow become more and more physiological as the tangle of facts unravels so that the ethology of the field inevitably becomes the ethology of the laboratory

First Time Up: An Insider\u27s Guide for New Composition Teachers
First time up?—an insider\u27s friendly question from 1960s counter-culture—perfectly captures the spirit of this book. A short, supportive, practical guide for the first-time college composition instructor, the book is upbeat, wise but friendly, casual but knowledgeable (like the voice that may have introduced you to certain other firsts). With an experiential focus rather than a theoretical one, First Time Up will be a strong addition to the newcomer\u27s professional library, and a great candidate for the TA practicum reading list. Dethier, author of The Composition Instructor\u27s Survival Guide and From Dylan to Donne, directly addresses the common headaches, nightmares, and epiphanies of composition teaching—especially the ones that face the new teacher. And since legions of new college composition teachers are either graduate instructors (TAs) or adjuncts without a formal background in composition studies, he assumes these folks as his primary audience. Dethier\u27s voice is casual, but it conveys concern, humor, experience, and reassurance to the first-timer. He addresses all major areas that graduate instructors or new adjuncts in a writing program are sure to face, from career anxiety to thoughts on grading and keeping good classroom records. Dethier\u27s own eclecticism is well-represented here, but he reviews with considerable deftness the value of contemporary scholarship to first-time writing instructors\u27 many of whom will be impatient with high theory. Throughout the work, he affirms a humane, confident approach to teaching, along with a true affection for college students and for teachers just learning to deal with them.https://digitalcommons.usu.edu/usupress_pubs/1155/thumbnail.jp
Local governance and public goods provision in rural China:
In developing countries, identifying the most effective community-level governance structure is a key issue and, increasingly, empirical evaluation of the effects of democratization on the provision of local public goods is needed. Since the early 1990s, tens of thousands of villages in rural China have held local-government elections, providing a good opportunity to investigate the effect of democratization on the level of public goods provision. Using a recent village survey conducted over a significant period of time, this paper compares governance by elected officials with that of appointed cadres and finds that elected officials tend to tax constituents less and provide them with higher levels of public service.

The composition and resilience of rockpool fish assemblages on the central Hawke's Bay coast New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Ecology at Massey University
Irregular pagination.Fish assemblages in rockpools on two intertidal platforms on the Central Hawke's Bay coast of New Zealand were studied from June 2000 to March 2001. Twenty-four species belonging to 14 families were collected from 226 rockpool censuses. The Tripterygiidae were the most speciose family, represented by 7 species. Fifty-seven percent of the total number of fish captured (n = 6133) belonged to a single species, the robust triplefin Grahamina capito. Common subtidal species contributed significantly to the taxocene, indicating that much of the rockpool fish fauna is an extension of that in the shallow subtidal fringe. However, two specialist intertidal species (Acanthoclinus fuscus and Bellapiscus medius) were relatively abundant in the collections. Significant relationships between rockpool fish assemblage structure, and rockpool habitat structure were discovered. Richness, abundance and biomass were generally greater in large pools with lots of shelter, located close to the low-tide mark. Further analysis revealed that assemblages in these pools contained many partial residents that were uncommon or absent from rockpools higher on the shore. Seasonality in the structure of rockpool fish assemblages was related primarily to recruitment events. During late spring and early summer, the abundance and density of resident species increased markedly as the result of an influx of settling larvae. However, species richness remained stable over the sampling period, probably because transient subtidal species (with the exception of the labrid, Notolabrus celidotus) did not contribute significantly to the rockpool fish community. The rockpool fish community appeared to be resilient: taxocene structure re-established between collection events. However, the level and rate of resilience appeared to be lower than described in other studies, as the effects of sampling were still measurable after 3-months. The recovery of richness, abundance and biomass of fish was seasonally dependent, being slow in winter and spring, but rapid during summer. Specialist intertidal species were generally the best recolonisers, whereas partial resident species were poor recolonisers, and relied mainly on larval recruitment to colonise rockpools
