Coyotes that fatally attacked a Canadian woman in 2009 were forced to rely on moose instead of smaller mammals for the bulk of their diet, and as a result of adapting to that unusually large food source, perceived a lone hiker as potential prey, a new study finds.
Article title: Mitochondrial adaptations to inactivity in diaphragm muscle fibers Authors: Alyssa D. Brown, Matthew J. Fogarty, Leah A. Davis, Debanjali Dasgupta, Carlos B. Mantilla, Gary C. Sieck From the authors: “Type I and IIa [diaphragm muscle] fibers were far…
Roughly half of all flowering plants are polyploid, meaning that they have more than two sets of chromosomes. Scientists believe polyploidy drives adaptation by giving organisms more genetic diversity. This research compared tetraploid (four copies) and octoploid (eight copies) varieties of switchgrass, and found that octoploid switchgrasses are generalists, able to tolerate a broad range of environmental conditions and expand their range into new areas.
Crows and ravens are well known for their black color and the harsh “caw” sound they make. They are intelligent birds that use tools, solve complex abstract problems and speak a volume of words. But what is less well appreciated is how diverse they are. Their diversity is accompanied by their ability to live all over the world in a variety of habitats.
The open oceans are harsh and hostile environments where insects might not be expected to thrive. In fact, only one insect group, ocean skaters, or water striders, has adapted to life on the open seas.
How these insects evolved to conquer the high seas, however, was not known.
Now, a study of the genetics of skaters by scientists from the National University of Singapore (NUS) and Scripps Institution of Oceanography at UC San Diego provides a clue. The answer has to do with when major currents in the eastern Pacific Ocean came into existence with each species of skater evolving to match the unique conditions of those currents.
Research from Wellesley College shows that despite being a clonal insect species, weevils use gene regulation to adapt to new food sources and pass down epigenetic changes to future generations.
A study led by Michael Moore at Washington University in St. Louis finds that dragonfly males have consistently evolved less breeding coloration in regions with hotter climates. The work reveals that mating-related traits can be just as important to how organisms adapt to their climates as survival-related traits.
Scientists have confirmed the species and origin of a colony of wild African vervet monkeys that landed in Dania Beach more than 70 years ago. They escaped from the Dania Chimpanzee Farm in 1948 and settled in a thick mangrove forest near the Fort Lauderdale-Hollywood International Airport in South Florida. The facility acted as a zoo and also provided primates imported from Africa as research subjects in the development of the polio vaccine and other medical research.
It’s well understood that a difficult childhood can increase the likelihood of mental illness, but according to new research from the University of South Australia, a happy and secure childhood does not always protect a child from developing a mental illness later in life.
New Brunswick, N.J. (Jan. 12, 2021) – Rutgers University–New Brunswick professors Robert E. Kopp and Pamela McElwee are available for interviews on how President-elect Joe Biden and his incoming administration could strengthen efforts to address climate change and protect the environment. Kopp, a professor in…
How the larvae of colorful clownfish that live among coral reefs in the Philippines are dispersed varies widely, depending on the year and seasons – a Rutgers-led finding that could help scientists improve conservation of species. Right after most coral reef fish hatch, they join a swirling sea of plankton as tiny, transparent larvae. Then currents, winds and waves disperse them, frequently to different reefs.
With restaurants and supply chains disrupted due to the global coronavirus pandemic, two-fifths of commercial fishermen surveyed from Maine through North Carolina did not go fishing earlier this year, according to a Rutgers study that also documented their resilience and adaptation. Of those who kept fishing, nearly all reported a decline in income compared with previous years, according to the survey of 258 fishers in the Northeast published in the journal PLOS ONE.
New Brunswick, N.J. (Oct. 23, 2020) – Rutgers Professor Pamela McElwee, an expert on Vietnam environmental issues, is available for interviews on the devastating flooding in that country this month and the flood threat posed by Typhoon Saudel. McElwee, who has done research…
New Brunswick, N.J. (Oct. 14, 2020) – Rutgers coastal expert Vanessa Dornisch is available for interviews on 10 steps residents can take to prepare for sea-level rise and adapt to increased coastal flooding. Dornisch, coastal training program coordinator at the…
New Brunswick, N.J. (Aug. 3, 2020) – Rutgers University–New Brunswick Professor Robert E. Kopp is available to discuss a major study released today on the global consequences of climate change on death rates. The study by the Climate Impact Lab,…
With a one-year National Science Foundation grant, David Ray and Diana Moreno Santillán are investigating how bats adapted to the virus.
University of Washington researchers have launched the King County COVID-19 Community Study — or KC3S — to gather data through April 19 on how individuals and communities throughout King County are coping with the measures put in place to combat the spread of the COVID-19 virus.
New Brunswick, N.J. (Dec. 4, 2019) – With sea-level rise threatening hundreds of millions of people, researchers must do a better job engaging communities and other stakeholders so they can make the best-informed decisions on how to adapt in the…
You’d think that losing 25 percent of your genes would be a big problem for survival. But not for red algae, including the seaweed used to wrap sushi. An ancestor of red algae lost about a quarter of its genes roughly one billion years ago, but the algae still became dominant in near-shore coastal areas around the world, according to Rutgers University–New Brunswick Professor Debashish Bhattacharya, who co-authored a study in the journal Nature Communications.
Hurricane Dorian is the latest example of a frightening trend. Extreme weather events are becoming more frequent, more severe and more widespread as a consequence of climate change. New research from Washington University in St. Louis provides important new insights into how different species may fare under this new normal. Faced with unprecedented change, animals and plants are scrambling to catch up — with mixed results.
New Brunswick, N.J. (Sept. 25, 2019) – Rutgers University–New Brunswick Professor Malin Pinsky and Rutgers coastal expert Lisa Auermuller are available to comment on a new United Nations report on climate change and ocean, coastal, polar and mountain ecosystems. More than…
Invasive mosquitoes at the northern limit of their current range are surviving conditions that are colder than those in their native territory. This new evidence of rapid local adaptation could have implications for efforts to control the spread of this invasive species.
