  • International project provides roadmap of Earth’s largest mass extinction

    MEDIA RELEASE: 5 November 2020 – R0169

    The most extensive mass extinction in Earth’s history took place about 252 million years ago when 90 per cent of ocean life and 70 per cent of life on land perished.

    In a study recently published in the journal Nature Geoscience, an international team of Earth scientists, including Brock University Professor Uwe Brand, provide a conclusive roadmap of the geochemical processes that led to this massive biotic extinction.

    “What we learned is the event occurred in pulses, with each pulse constricting the hospitable environment further and further, cascading down to the extinction event over a short geological timeline,” Brand said.

    The team, including members from Canada, Germany and Italy, determined that a combination of ocean pH changes and the release of immense quantities of carbon dioxide during volcanism events in what is now Siberia caused ocean acidification and global warming.

    Ocean acidification restricted livable parameters for marine life, while warming increased temperature and rainfall globally. These pulses caused weathering and overloaded oceans with nutrients, which depleted their dissolved oxygen.

    “A key to the discovery was found in the shells of brachiopod fossils, which stored the geochemical signals we needed to understand the process,” Brand said.

    “The team from Italy of Renato Posenato, Lucia Angiolini and Claudio Garbelli was instrumental in locating fossils that recorded the events before and during parts of the extinction,” Brand said. “They know the best localities, geography and fossil sites.”

    The German team — including Hana Jurikova, Marcus Gutjahr, Klaus Wallmann, Sascha Flögel, Volker Liebetrau, Michael Wiedenbeck and Anton Eisenhauer — had the equipment and expertise necessary to analyze the isotopes found in the fossils and to model the processes.

    The team’s research presents evidence that the fossil brachiopod tests demonstrate ocean pH declined significantly causing detrimental harm to ocean life. In addition, the team’s geochemical model shows how the mass release of carbon dioxide and global warming effects further damaged the environment where life could survive.

    The study was conducted within the framework of the European Union-funded Innovative Training Networks project called BASE-LiNE Earth, which received funding to train 15 PhD students and led to the research being presented.

    “The study’s conclusive findings are the result of an excellent collaboration between Brand and the talented teams from Germany and Italy,” said Ejaz Ahmed, Dean of Brock’s Faculty of Mathematics and Sciences. “We are proud of their work on this global partnership.”

  • Fall Preview to virtually provide students with a taste of Brock life

    MEDIA RELEASE: 4 November 2020 – R0168

    Instead of bringing prospective students and their families to campus for Fall Preview next week, Brock University will bring the campus to them.

    The University has planned an action-packed online event Monday, Nov. 9 in place of the traditional one-day affair that typically draws thousands of Badger hopefuls looking to learn more about Brock’s offerings.

    Virtual Fall Preview — for students considering joining Brock in January or September — will include more than 20 live sessions detailing various programs and aspects of academic and student life, as well as student panels, mock lectures, a live chat and live campus tours that can be enjoyed from the comfort of home.

    In addition to guided tours of the main campus, which run every 30 minutes throughout the day, viewers have the opportunity to participate in specialized tours of the Goodman School of Business and Marilyn I. Walker School of Fine and Performing Arts. Student ambassadors, who lead the tours, will share their personal Brock experiences and field questions from viewers.

    “It has been pretty rewarding to see so many members of the University community — faculty, staff and community partners — come together to contribute to Fall Preview,” said Carly Dugo, Recruitment Officer, Campus Initiatives. “It’s a prime example of the sense of community and collaborative environment that we’re always cultivating at Brock.

    “These may be challenging times, but we’ve made the most of it,” Dugo said in reference to the ongoing COVID-19 pandemic, which resulted in the cancellation of in-person tours and major recruitment events such as the Ontario Universities’ Fair. “Thanks to the collaboration we’ve experienced, we’re still offering just as much, and in some ways, even more than we have in the past to ensure prospective students can make an informed decision as they plan for the future.”

    Fall Preview will include a number of opportunities for students and their families to ask questions and interact with department heads, faculty members, staff and existing Brock students.

    “We’re trying to provide as much virtual face-to-face interaction as we can,” Dugo said. “And by having Fall Preview online, we’re hoping to connect with students and their family members who otherwise may not have been able to make it to a all-day campus event.”

    In addition to Fall Preview, Brock’s Recruitment team has been offering virtual tours and one-on-one chats on an ongoing basis, and delivering hundreds of presentations to high school students not only during the day but also on evenings and weekends to accommodate various schedules.

    “We’ve had a lot of students engage with us. They’re asking a ton of great questions and are really excited,” said Dugo. “We’re trying to give them every possible way to connect with us and we’ve been seeing a lot of success so far.”

    Since virtual tours were relaunched at the beginning of September, the number of attendees is up more than 50 per cent, said Matt Melnyk, Director of Student Recruitment. Surveys from the tours, he added, have shown the personal experience being offered is helping to boost interest in applying to Brock.

    With the secondary school system undergoing changes this year due to COVID-19, it has taken students a bit of time to adjust before turning their focus to the next steps in their educational journey, he said. As a result, Brock is now seeing a “big spike in activity” from prospective students wanting to learn more about their options.

    “We know the fall semester has been challenging for them,” Melnyk said, “so we’re making ourselves accessible and trying to reach out to them in every way possible.”

    What makes Brock stand out, he said, is the strength of its community and its commitment to supporting students, which has led to the University ranking No. 1 for the third consecutive year for mental health supports for students in the annual Maclean’s University Rankings.

    “We’re demonstrating through our actions that we’re available to help students through this process.”

    Lynn Wells, Provost and Vice-President, Academic, praised the University community for coming together to make Fall Preview and other recruitment initiatives possible.

    “Fall Preview is an important day on the calendar, providing an opportunity to celebrate the academic and student experience Brock offers and to share it with a new group of prospective students,” she said.

    “While we would much rather be hosting this year’s event in person, students, staff, faculty members and librarians from around the University have put significant effort into showcasing the best of Brock. I want to thank them all for their hard work and service to the University in this exceptional year.”

    Fall Preview content will go live Monday, Nov. 9 at 8:30 a.m. and will remain available throughout the fall, allowing students and their families to watch sessions at their own convenience.
