Botulism in waterbirds: Mortality rates and new insights into how it spreads

Botulism in waterbirds: Mortality rates and new insights into how it spreads

Outbreaks of botulism killed large percentages of waterbirds inhabiting a wetland in Spain. During one season, more than 80 percent of gadwalls and black-winged stilts died. The botulinum toxin’s spread may have been abetted by an invasive species of water snail which frequently carries the toxin-producing bacterium, Clostridium botulinum, and which is well adapted to […]

Glynnis Hood, professor of environmental science at Augustana Campus, lives near Lake Miquelon and guides students’ research in the wetlands of the Beaver Hills area. An ecologically rich area of Alberta that is home to a University of Alberta research station and fertile ground for dozens of researchers over the years has won international recognition. […]

Gene blocking lettuce germination also regulates flowering time

Gene blocking lettuce germination also regulates flowering time

Kent Bradford, left, and Alfred Huo, seen here with a flowering lettuce plant, found that lettuce could be prevented from flowering by increasing the expression of a specific microRNA in the plants. The high levels of this microRNA prevent the plant from transitioning to adulthood and flowering, and the plant continues to make numerous baby […]

Songbirds ‘teach chicks before they hatch’

Songbirds ‘teach chicks before they hatch’

Red-backed Fairy-wren females behave just like their relatives, the Superb Fairy-wren, ornithology experts at Flinders have found. Many birds learn their songs from their parents, but what if they could get a head start? A new paper, published in The Auk: Ornithological Advances, expands Flinders University research into how Australian fairy-wrens start learning to imitate […]

Antarctic birds recognize individual humans

New bacteria from anammox wastewater treatment

New bacteria from anammox wastewater treatment

Removal of nitrogen from wastewater is crucial to maintain water quality. A novel wastewater treatment technology based on «anammox» bacteria, capable of removal of nitrogen compounds anaerobically, has greatly improved this process. After a decade of operation of a full scale anammox reactor, researchers of the Radboud University and BE-Basic have studied the microorganisms in […]

Restoring the American chestnut

Restoring the American chestnut

Tissue-cultured American chestnut shoots are shown in a post-rooting medium containing activated charcoal. Experiments showed that activated charcoal enhanced root growth but slightly decreased shoot tip survival. Credit: Allison Oakes. The American chestnut was once a mainstay in hardwood forests as far north as Maine and as far south as Georgia and Mississippi. A massive […]
