Bar Harbor, ME, United States

College of the Atlantic , founded in 1969, is a private, liberal-arts college located in Bar Harbor on Mount Desert Island, Maine, United States. It awards bachelors and masters degrees solely in the field of human ecology, an interdisciplinary approach to learning. Focus areas include arts and design, environmental science, humanities, international studies, sustainable food systems, and socially responsible business. The college is small, with approximately 364 students and a full-time faculty of 35, and 15 part-time faculty. Tenets of the pedagogy include field-based or applied learning; small, seminar-style classes; student-directed projects; community involvement; and interdisciplinary learning. COA has a strong commitment to the environment and was the first college to be carbon neutral and one of the first to divest fossil fuel holdings from its endowment. The college appears on most of the top "green school" lists. The campus consists of 37 acres on Frenchman Bay, two organic farms, two off-shore island research stations, and a 100-acre protected area. The farms, Beech Hill Farm and Peggy Rockefeller Farms, are living laboratories for classes and student research. Peggy Rockefeller Farms includes livestock, crops, orchards. Beech Hill Farm provides produce. Both supply the award-winning dining hall with organic produce, eggs, and meat. The off-shore island properties include the Alice Eno Field Research Station on Great Duck Island where students conduct studies on Leach's storm petrels, guillemots, gulls, sparrows and other fields of natural history. The Edward McCormick Blair Research station on Mount Desert Rock is a center for the study of marine mammals and oceanographic issues. Wikipedia.

Cardiopulmonary nematodes of dogs and cats cause parasitic diseases of central relevance in current veterinary practice. In the recent past the distribution of canine and feline heartworms and lungworms has increased in various geographical areas, including Europe. This is true especially for the metastrongyloids Aelurostrongylus abstrusus, Angiostrongylus vasorum and Crenosoma vulpis, the filarioid Dirofilaria immitis and the trichuroid Eucoleus aerophilus (syn. Capillaria aerophila). The reasons of this emergence are little known but many drivers such as global warming, changes in vector epidemiology and movements in animal populations, may be taken into account. The purpose of this article is to review the knowledge of the most important heartworm and lungworm infections of dogs and cats in Europe. In particular recent advances in epidemiology, clinical and control are described and discussed. © 2010 Traversa et al; licensee BioMed Central Ltd. Source

Most mycoinsecticides require a carrier of natural or synthetic oils for them to be effective when sprayed on forest-defoliating caterpillars such as the eastern spruce budworm (Choristoneura fumiferana (Clemens)). Two isolates of Beauveria bassiana conidia were formulated in natural (vegetable) and synthetic (mineral) oils and tested against late instar larvae of the budworm. Topical application showed the ARSEF 1850 isolate to be more effective than a commercially available strain. Additional laboratory spray trials using a hand-held spinning disc sprayer showed that the ARSEF 1850 natural oil formulation significantly increased mortality when compared with controls. The use of oil-formulated B. bassiana conidia should be considered for future budworm management under the integrated pest management of this pest in North America. © 2016, National Research Council of Canada.

This paper discusses statistical modelling for data with a hierarchical structure, and distinguishes in this context between three different meanings of the term hierarchical model: to account for clustering, to investigate variability and separate predictive equations at different hierarchical levels (multi-level analysis), and in a Bayesian framework to involve multiple layers of data or prior information. Within each of these areas, the paper reviews both past developments and the present state, and offers indications of future directions. In a worked example, previously reported data on piglet lameness are reanalyzed with multi-level methodology for survival analysis, leading to new insights into the data structure and predictor effects. In our view, hierarchical models of all three types discussed have much to offer for data analysis in veterinary epidemiology and other disciplines. © 2013 Elsevier B.V. Source

Se-Te alloy nanocrystals (NCs) were synthesized in aqueous micellar phase at 85 °C by using Na2SeO3/Na2TeO 3 as Se/Te source in the presence of different amounts of hydrazine (i.e., 0.1-3.6 M) as reducing agent over the entire mole fraction range of Se (xSe) from xSe = 0 to 1. The shape, structure, and composition of alloy NCs were characterized by scanning electron microscopic (SEM), transmission electron microscopic (TEM), and energy dispersive X-ray spectroscopic (EDS) measurements. Despite many similar characteristic features of elemental Se and Te, a drastic change in the morphology of NCs was observed from xSe = 0 to 1. Amorphous water-soluble Se nanoparticles were obtained at xSe = 1 in the presence of excess of hydrazine, whereas long nanoribbons of several micrometers of Te were produced at xSe = 0. In the intermediate mole fractions, a smooth transition in the morphology from predominantly rhombohedral in the Se rich-region to long nanoribbons in the Te rich-region of the mixtures was observed. At relatively much lower hydrazine concentration, large plate-like morphologies were obtained at xSe = 1, while the morphologies at other mole fractions were slightly distorted with greater effect in the Se rich-region of the mixtures. A careful EDS analysis on each kind of morphology revealed a homogeneous mixing between elemental Se and Te but with a significantly nonideal behavior over the whole mole fraction range. All results were summarized in a phase diagram depicting the relationship between stochiometric amounts of Se and Te with their atomic percent in crystalline phase. NCs were always highly rich in the Te contents even in the Se rich-region of the mixtures and the overall growth was predominantly driven by metalloid (crystalline) nature of Te rather than nonmetallic (amorphous) nature of Se. © 2010 American Chemical Society.

This manuscript was written in honour of Dr. Preben Willeberg to illustrate some tools that may be useful to " make surveillance happen" and to build bridges between science and application in animal health surveillance.The paper illustrates how four elements (science, project management, communication and documentation) may be combined with some tools into a practical framework for Foreign Animal Disease surveillance. Specifically, I will show how the four elements are essential to make surveillance happen and provide a link between science and application in animal health surveillance. The Canadian Notifiable Avian Influenza Surveillance system is used as an example.In surveillance for Foreign Animal Diseases (FAD), with veterinary authorities as the lead and with many stakeholders, . project management can support . science in building evidence (. documentation) that can be delivered (. communicated) to trade negotiators and international trade partners. To bridge the gap between science and application in FAD surveillance I propose that we need people with skills in science, project management, communication and documentation. © 2012. Source
