El retamo espinoso (Ulex europaeus L.), una planta europea altamente agresiva en Colombia, afecta los páramos y desplaza especies nativas, generando preocupación ecológica. Este estudio investiga su biología, abarcando banco de semillas (113 semillas/m² a 5 cm), acumulación de biomasa (0,006732 g/día en 481 días), fenología en estado juvenil durante 378 días sin floración, y resultados preliminares del uso de herbicidas en los tallos. Estos datos iniciales son cruciales para desarrollar métodos de control, abordando disciplinas como ecología, fenología, hábitat, herbicidas, malezas, biodiversidad y bioseguridad.


Mp: 766 Roadside Rights-Of-Way As Pollinator Habitat: A Literature Review, Brianne Du Clos Jun 2023

Mp: 766 Roadside Rights-Of-Way As Pollinator Habitat: A Literature Review, Brianne Du Clos

Miscellaneous Publications

Pollination of crops and naturally-occurring flowering plants is a critical ecosystem service provided by managed and unmanaged animal pollinators. Insects are the most studied pollinators, particularly managed honey bees, unmanaged wild bees, and butterflies. Bees and butterflies thrive in early-successional habitat featuring grasses, exposed soil, wildflowers, and shrubs, which is consistently found within transportation and utility rights-of-way (ROW). However, intensive management of ROW can reduce the amount of high-quality pollinator habitat; such practices include frequent mowing, broadcast herbicide use, and planting non-native cool season grasses. Here, we review peer-reviewed academic and non-peer reviewed gray literature describing ROW management practices and …


A Monographic Revision Of The Jewel Scarabs Genus Chrysina From Panama, Colombia, And Ecuador (Coleoptera: Scarabaeidae: Rutelinae: Rutelini), Manuel D. Barria Feb 2023

A Monographic Revision Of The Jewel Scarabs Genus Chrysina From Panama, Colombia, And Ecuador (Coleoptera: Scarabaeidae: Rutelinae: Rutelini), Manuel D. Barria

Zea E-Books Collection

The work is a taxonomic revision of 28 species of the genus Chrysina Kirby (Scarabaeidae: Rutelinae: Rutelini) found in Panama (25), Colombia (2), and Ecuador (3). Chrysina tricolor (Ohaus), Chrysina chalcothea (Bates), and Chrysina cupreomarginata (F. Bates) are new re­cords for Panama. A new country record from northern Colombia is confirmed for Chrys­ina mercedesae Barria. Chrysina gaitalica Curoe and Hawks and Chrysina galbina Hawks are discovered at new localities in Panama; females of both species are discovered and described. Chrysina aurora (Bates) known from other localities in the west of the country, is rediscov­ered in Veraguas province 147 years after …

Monteverde: Ecology And Conservation Of A Tropical Cloud Forest - 2014 Updated Chapters, Nalini M. Nadkarni, Nathaniel T. Wheelwright Jan 2014

Monteverde: Ecology And Conservation Of A Tropical Cloud Forest - 2014 Updated Chapters, Nalini M. Nadkarni, Nathaniel T. Wheelwright

Bowdoin Scholars' Bookshelf

The Monteverde Cloud Forest Reserve has captured the worldwide attention of biologists, conservationists, and ecologists and has been the setting for extensive investigation over the past 40 years. Roughly 40,000 ecotourists visit the Cloud Forest each year, and it is often considered the archetypal high-altitude rain forest. “Monteverde: Ecology and Conservation of a Tropical Cloud Forest”, edited by Nalini Nadkarni and Nathaniel T. Wheelwright (Oxford University Press, 2000 and Bowdoin’s Scholar’s Bookshelf. Book 1 ), features synthetic chapters and specific accounts written by more than 100 biologist and local residents, presenting in a single volume everything known in 2000 about …


Tb206: Biodiversity Of The Schoodic Peninsula: Results Of The Insect And Arachnid Bioblitzes At The Schoodic District Of Acadia National Park, Maine, Donald S. Chandler, David Manski, Charlene Donahue, Andrei Alyokhin Sep 2012

Tb206: Biodiversity Of The Schoodic Peninsula: Results Of The Insect And Arachnid Bioblitzes At The Schoodic District Of Acadia National Park, Maine, Donald S. Chandler, David Manski, Charlene Donahue, Andrei Alyokhin

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. …


Tb192: The Use Of Glyphosate Herbicides In Managed Forest Ecosystems And Their Effects On Non-Target Organisms With Particular Reference To Ants As Bioindicators, Kerry F.L. Guiseppe, Francis A. Drummond, Constance Stubbs, Stephen Woods Jan 2006

Tb192: The Use Of Glyphosate Herbicides In Managed Forest Ecosystems And Their Effects On Non-Target Organisms With Particular Reference To Ants As Bioindicators, Kerry F.L. Guiseppe, Francis A. Drummond, Constance Stubbs, Stephen Woods

Technical Bulletins

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 Sep 2005

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 …


Tb190: Spider Predation In Agroecosystems: Can Spiders Effectively Control Pest Populations., Darlene Maloney, Francis A. Drummond, Randy Alford Aug 2003

Tb190: Spider Predation In Agroecosystems: Can Spiders Effectively Control Pest Populations., Darlene Maloney, Francis A. Drummond, Randy Alford

Technical Bulletins

Recent trends in agriculture towards reduced pesticide use and ecological sustainability have lead to increased interest in spiders as potential biological control agents. Although the Chinese have augmented spider populations in field crops as a pest management strategy for centuries, much debate remains as to whether spiders will effectively control pest populations in U.S. agricultural ecosystems. This technical bulletin reviews the literature to describe the reduction of insect pest densities by spiders and the effects of pesticides on spiders. In addition to addressing the question of whether spiders can be effective biocontrol agents, the authors outline techniques to conserve and …
