The Scotsman reported on the recently published findings of a biodiversity research project led by the University of St. Andrews in collaboration with researchers from around the world, including Brian McGill, an associate professor of ecological modeling at the University of Maine. The researchers found that despite fears of a global biodiversity crisis, there has been no consistent drop in the number of species seen locally around the world. The research into 100 communities and a total of 35,000 species found that while there were major changes in species found in any one place, the total number of plants and animals did not significantly change. The findings were published in the journal Science.
WLBZ (Channel 2) spoke with Robert Rice, a professor of wood science and technology at the University of Maine, for a report on the scrutiny surrounding a proposed $25 million Finance Authority of Maine (FAME) loan that would support Cate Street Capital’s Thermogen Project that aims to build a pellet mill in Millinocket that uses new, steam-based technology. Rice, a consultant to FAME on the project, says the new method is a radical change, but is an improvement in technology. He warned Thermogen will need about three times as much biomass to make pellets using steam, which has to be taken into account.
The project, which was led by the University of St. Andrews in collaboration with researchers from around the world — including the University of Maine’s Brian McGill — found that despite fears of a global biodiversity crisis, there has been no consistent drop in the number of species found locally around the world.
The research into 100 communities and a total of 35,000 species — from trees to starfish — found that while there were major changes in species found in any one place, the total number of plants and animals did not significantly change, according to the release.
The researchers, who were surprised by the findings, say the study should not detract from the threat many of the world’s species are under, but that policymakers should focus on changes in biodiversity composition, as well as loss, the release states.
“Conservation scientists will need to shift from just talking about how many species are found in a place to talking about which species are found in a place,” said McGill, an associate professor of ecological modeling. “Put simply, species composition changed more often than species number, and these kinds of changes should be a focus for future study.”

Sandra De Urioste-Stone, assistant professor of nature-based tourism, and John Daigle, associate professor of forest recreation management, have received a $34,499 grant from the Maine Department of Agriculture, Conservation and Forestry for the study: “How Well Are We Serving the Outdoor Recreation Public?” The purpose of this study is to investigate perspectives on outdoor recreation preferences and priorities, and perceptions on tourism development to help the Maine Bureau of Parks and Lands and other outdoor recreation managers to better understand current demand and improve decision-making. An online survey will be used to test conventional wisdom and open up new thinking regarding what the public wants and how they can best be served. In addition, study participants will be asked questions about their attitudes and beliefs about developing sustainable tourism in their communities. Data collected will be used to develop the 2015–20 Maine State Comprehensive Outdoor Recreation Plan (SCORP). The plan requires that an analysis of outdoor recreation demand, supply, trends, and ultimately priorities be documented.
The survey population for this study seeks to entice responses from both the general residents of Maine as well as nonresidents who have recreated in Maine and have paid some type of recreation fee for fishing, hunting, camping reservations, etc.
While the data collected on recreational preferences and behaviors will benefit the Maine Bureau of Parks and Lands, the questions related to sustainable tourism will have new scientific significance. Questions on sustainable tourism will utilize an attempt to revalidate the Sustainable Tourism Attitude Scale, a published psychometric instrument that has not yet been implemented on a statewide scale.
WABI (Channel 5) reported the Black Bear Food Guild, a community-supported agriculture (CSA) program that is organized and managed by students in the University of Maine’s Sustainable Agriculture program, is offering CSA shares for the season. The guild is selling full ($475), half ($300) and quarter ($175) shares. Shareholders can pick up fresh produce each week from mid-June to October at the university’s Rogers Farm.
WVII (Channel 7) spoke with John Jemison, a soil and water quality specialist with the University of Maine Cooperative Extension, and two members of the Black Bear Food Guild for a report about Maine’s high commitment to local foods. Jemison said people want to know what’s in their food and how it’s grown, and he has seen a lot of that interest in Maine. UMaine students and Black Bear Food Guild members Laura Goldshein and Lindy Morgan spoke about their work within the guild. The Black Bear Food Guild is a community-supported agriculture (CSA) program that is organized and managed by sustainable agriculture students and offers CSA shares to community members in an effort to increase accessibility to fresh, seasonal produce.
Phys.org published an article on research conducted by a University of Maine team that found stratification of the North Atlantic Ocean contributed to summer warming and glacial melting in Scotland during the period recognized for abrupt cooling 12,900 to 11,600 years ago in the Northern Hemisphere. Prevailing scientific understanding has been that glaciers advanced in the Northern Hemisphere throughout most of the Younger Dryas Stadial (YDS) — a 1,300-year period of dramatic cooling. However, the researchers determined carbon-dated bog sediment indicates the 9,500-square-kilometer ice cap over Rannoch Moor in Scotland retreated at least 500 years before the end of the YDS.
Crisanne Blackie, the University of Maine’s health and legal professions career specialist, spoke to the Portland Press Herald for an article about a report that states Maine is likely to suffer a shortage of medical professionals unless the industry boosts student enrollment at health care-related schools and recruits more workers from outside Maine. The report was published by the Maine Department of Labor’s Center for Workforce Research and Information. Blackie said UMaine is trying to maintain an adequate number of doctors in the state by taking part in the Maine Track Program. The program is a partnership among Tufts University School of Medicine in Boston, Maine Medical Center in Portland and Maine colleges and universities that allows pre-med students in Maine to compete for fast-tracked enrollment at Tufts University’s medical school.
The Black Bear Food Guild, a community-supported agriculture (CSA) program that is organized and managed by students in the University of Maine’s Sustainable Agriculture program, is offering CSA shares for the season.
In an effort to increase accessibility to fresh, seasonal produce for all members of the community, the Black Bear Food Guild is offering full, half and quarter shares. The 2014 season marks the first time the guild will be offering quarter shares, which are recommended for one person and an ideal choice for students. Quarter shares cost $175. Full shares are $475 and will feed four people, and half shares are $300 and will feed two people.
Shareholders can pick up produce each week at the university’s Rogers Farm. The guild’s season runs from mid-June through early October.
A limited number of shares are available on a first-come, first-served basis. Those interested in purchasing a share for the 2014 season should email the Black Bear Food Guild at firstname.lastname@example.org.
Since 1994, students have farmed two acres of MOFGA-certified organic vegetables and cut flowers on Rogers Farm. The farmers for the 2014 Black Bear Food Guild are Laura Goldshein, Lindy Morgan and Abby Buckland.
A University of Maine research team says stratification of the North Atlantic Ocean contributed to summer warming and glacial melting in Scotland during the period recognized for abrupt cooling 12,900 to 11,600 years ago in the Northern Hemisphere.
Prevailing scientific understanding has been that glaciers advanced in the Northern Hemisphere throughout most of the Younger Dryas Stadial (YDS) — a 1,300-year period of dramatic cooling.
But carbon-dated bog sediment indicates the 9,500-square-kilometer ice cap over Rannoch Moor in Scotland retreated at least 500 years before the end of the YDS, says Gordon Bromley, a postdoctoral associate with UMaine’s Climate Change Institute (CCI).
“Our new record, showing warming summers during what traditionally was believed to have been an intensely cold period, adds an exciting new layer of complexity to our understanding of abrupt events and highlights the fact that there is much yet to learn about how our climate can behave,” Bromley says.
“This is an issue that is becoming ever more pressing in the face of global warming, since we really need to know what Earth’s climate system is capable of. But first we have to understand the full nature of abrupt climate events, how they are manifest ‘on the ground.’ And so we were compelled to investigate the terrestrial record of the Younger Dryas, which really is the poster child for abrupt climate change.”
Glaciers, says Bromley, respond to sea surface temperatures and Scotland is immediately downwind of the North Atlantic Ocean.
“Scotland was the natural choice as it lies within the North Atlantic Ocean — widely believed to be a driver of climatic upheaval — and thus would give us a robust idea of what really transpired during that critical period,” he says.
What the team found was that amplified seasonality driven by greatly expanding sea ice resulted in severe winters and warm summers.
While sea ice formation prevented ocean to atmosphere heat transfer during winters, melting of sea ice during summers created a stratified warmer freshwater cap on the ocean surface, he says. The increased summer sea surface temperature and downwind air temperature melted the glaciers.
Bromley says this research highlights the still-incomplete understanding of abrupt climate changes throughout Earth’s history.
“Ever since the existence of abrupt climate change was first recognized in ice-core and marine records, we’ve been wrestling with the problem of why these tumultuous events occur, and how,” he says.
Kurt Rademaker, Brenda Hall, Sean Birkel and Harold W. Borns, all from UMaine’s Climate Change Institute and School of Earth and Climate Sciences, are part of the research team. So too is Aaron Putnam, previously from CCI and now with Lamont-Doherty Earth Observatory at Columbia University/Earth Institute. Joerg Schaefer and Gisela Winckler are also with Lamont-Doherty Earth Observatory and Thomas Lowell is with the University of Cincinnati.
The team’s research paper, Younger Dryas deglaciation of Scotland driven by warming summers, was published April 14 on the “Proceedings of the National Academy of Sciences” website.
