  • Logged Tropical Rainforests Still Support Biodiversity Even When the Heat Is On

    Tropical rainforests continue to buffer wildlife from extreme temperatures even after logging, a new study has revealed.

  • University of Toronto biologists discover an epigenetic key to unlock behavioural change in fruit flies

    When it comes to behaviour, researchers have moved beyond the “nature versus nurture” debate. It’s understood that genes and environment both play a role. However, how they interact at a molecular level to shape behaviour is still unclear.

    A new study led by scientists at the University of Toronto sheds valuable light on this relationship. The paper, published in  Proceedings of the National Academy of Sciences of the United States of America, reveals how epigenetics – changes in gene expression that do not change DNA – interact with genes to shape different feeding behaviours in fruit flies. This research unlocks the molecular mechanism that leads “rover” flies to forage for food more than “sitter” flies.

  • Scientists Map Monogamy, Jealousy in the Monkey Mind

    It’s perhaps one of the most common emotions to feel in a relationship, but one that’s virtually untouched when it comes to studying relationships in monogamous primate species. What scientists have recently discovered about jealousy in pair-bonded titi monkeys at the California National Primate Research Center (CNPRC) offers insight into human emotions and their consequences.

  • A New Butterflyfish— A Rare, Surprise Find— Is Described from the Philippine “Twilight Zone” and Academy Exhibit

    A newly described species of brown-and-white Philippine butterflyfish—the charismatic Roa rumsfeldi—made a fantastic, 7,000-mile journey before surprising scientists with its unknown status. Live specimens collected from 360 feet beneath the ocean’s surface in the Philippine’s Verde Island Passage escaped special notice until a single black fin spine tipped off aquarium biologists back in San Francisco. Deep-diving researchers from the California Academy of Sciences’ Hope for Reefs team—with genetic sequencing help from a parent–son team—share their discovery of a fifth species of Roa this week in ZooKeys.

  • Illinois Sportfish Recovery a Result of 1972 Clean Water Act, Scientists Report

    Populations of largemouth bass, bluegill, catfish and other sportfish are at the highest levels recorded in more than a century in the Illinois River, according to a new report. Their dramatic recovery, from populations close to zero near Chicago throughout much of the 20th century, began just after implementation of the Clean Water Act, the researchers say.

  • DNA Tests on Albatross Poo Reveal Secret Diet of Top Predator

    A study that used DNA tests to analyse the scats of one of the world’s most numerous albatrosses has revealed surprising results about the top predator’s diet.

  • How Bees Find Their Way Home

    How can a bee fly straight home in the middle of the night after a complicated route through thick vegetation in search of food? For the first time, researchers have been able to show what happens in the brain of the bee.

  • Beyond Biodiversity: A New Way of Looking at How Species Interconnect

    In 1966, an ecologist at the University of Washington named Robert Paine removed all the ochre starfish from a short stretch of Pacific shoreline on Washington’s Olympic Peninsula. The absence of the predator had a dramatic effect on its ecosystem. In less than a year, a diverse tidal environment collapsed into a monoculture of mussels because the starfish was no longer around to eat them.

  • Bycatch Responsible for Decline of New Zealand Sea Lion

    Getting caught in fishing nets is a major cause of death for the increasingly endangered New Zealand sea lion, according to new research from the University of Otago, Massey University and the University of Toronto.

  • Best way to save the caribou? Look at white-tailed deer and moose

    The most effective way to save North America’s dwindling caribou herds is to keep numbers of invading prey animals—like deer and moose—low, according to a new UAlberta research study.

    “Prey like moose and deer are expanding in numbers and range because of logging and climate change,” said Robert Serrouya, a postdoctoral fellow in biological sciences professor Stan Boutin’s lab.
