Technical Bulletins
Bioblitzes have become a popular approach to involve scientists and the public in studying biodiversity. They reinforce the idea that natural areas are resources of scientific and educational value and are a way of engaging the public in experiencing the natural world. A bioblitz is typically conducted over a 24-hour period in a targeted area, with the goal of documenting the presence of as many species as possible. Scientists and “weekend naturalists,” along with other individuals who enjoy being in the field, are asked to attend bioblitzes as volunteers to help in finding and identifying as many species as possible. …

Tb199: Ant–Homopteran Relationships: Relevance To An Ant Invasion In Maine, Katherine E. Mcphee, Eleanor Groden, Francis A. Drummond
Technical Bulletins
The richness and diversity of native ant species on Mt. Desert Island, Maine, have been reduced in areas infested with Myrica rubra (European red ant). In general, the success of invasive ant species has been attributed to interference and exploitative competition coupled with the ants’ opportunistic diets. In field experiments on Mount Desert Island, Maine, M. rubra discovered and recruited to baits faster than native ants. This study also showed that M. rubra displaced most native ant species from food resources (Garnas 2005). This, together with M. rubra’s aggressive defense of invaded territories, has led to fewer native ants in …

This publication reviews and synthesizes the results of many research studies designed to elucidate the ecological effects of the herbicide glyphosate used in forested landscapes. We have not intended our review to be an exhaustive review of all published studies (both laboratory and field investigations) concerned with faunal and floral glyphosate interactions and the environmental fate of glyphosate. We particularly focused on studies that had relevance to north temperate forest ecosystems and selected published investigations to incorporate into our review that cover a wide range of faunal and floral taxa that might be exposed to herbicides during applications.
Tb191: Conservation And Management Of Native Bees In Cranberry, Jennifer L. Loose, Francis A. Drummond, Constance Stubbs, Stephen Woods
Tb191: Conservation And Management Of Native Bees In Cranberry, Jennifer L. Loose, Francis A. Drummond, Constance Stubbs, Stephen Woods
Technical Bulletins
Threats to agriculturally important pollinators have serious implications for human beings. A loss of bees translates to less successful crop pollination, thus reduced yield and poorer quality fruits. Native bees have the potential to serve as commercial pollinators. A diverse pollinator complex comprised of both honey bees and native bees should result in stable pollination levels and should be resistant to threats such as disease, fluctuating honey and crop prices, and honey bee transportation costs. Adding the goal of native bee conservation to land management increases the ecological integrity of an ecosystem by conserving a unique biological interaction that is …

Tb113: A Field Test Of Mating-Suppression Using The Spruce Budworm Sex Pheromone, J. B. Dimond, D. G. Mott, W. P. Kemp, J. H. Krall
Technical Bulletins
Spruce budworm sex pheromone was dispersed from aircraft over forest land in Maine in late June, 1980. A major goal was to sample pheromone concentrations in air to determine whether the formulation would provide the steady, sustained release of chemical believed required for interfering with the mating process of the moths. Since pheromone was going to be applied for purposes of analyses of air, we believed we should also study some behavioral effects on spruce budworm populations. The principal body of data involved the ability of male budworm moths to orient to point sources of pheromone in pheromone-treated and untreated …
