Invasive species with charisma have it easier
on April 6, 2020 at 3:25 pm
It's the outside that counts: Their charisma has an impact on the introduction and image of alien species and can even hinder their control. An international research team have investigated the influence of charisma on the management of invasive species.
Scientists discover legacy of past weather in stories of prairie plant restoration
on April 6, 2020 at 2:08 pm
Scientists have investigated fields of data going back 20 years to find out why some replanted prairies are healthier than others.
Tiny fly from Los Angeles has a taste for crushed invasive snails
on April 1, 2020 at 5:07 pm
Scientists are discovering plenty of minute insects that are new to science, but they are still only guessing what the lifestyles of some of these species are. Scientists have now found out that one particular species of tiny phorid fly has an unusual taste for smashed invasive snails.
Plant disease primarily spreads via roadsides
on April 1, 2020 at 3:17 pm
A precise statistical analysis reveals that on the Åland Islands a powdery mildew fungus that is a common parasite of the ribwort plantain primarily spreads via roadsides because traffic raises the spores found on roadsides efficiently into the air.
Bison in northern Yellowstone proving to be too much of a good thing
on March 31, 2020 at 1:31 pm
Increasing numbers of bison in Yellowstone National Park in recent years have become a barrier to ecosystem recovery in the iconic Lamar Valley in the northern part of the park.
How forests are changing in response to global warming
on March 30, 2020 at 10:16 pm
As the climate is changing, so too are the world's forests. From the misty redwoods in the west to the Blue Ridge forest of Appalachia, many sylvan ecosystems are adapting to drier conditions.
Where lions roam: West African big cats show no preference between national parks, hunting zones
on March 30, 2020 at 1:34 pm
West African lions are a critically endangered subpopulation, with an estimated 400 remaining and strong evidence of ongoing declines.
Animals keep viruses in the sea in balance
on March 27, 2020 at 3:36 pm
A variety of sea animals can take up virus particles while filtering seawater for oxygen and food. Sponges are particularly efficient.
New framework will help decide which trees are best in the fight against air pollution
on March 26, 2020 at 12:08 pm
A study has provided a comprehensive guide on which tree species are best for combating air pollution that originates from our roads -- along with suggestions for how to plant these green barriers to get the best results.
Plants and animals aren't so different when it comes to climate
on March 25, 2020 at 12:20 am
A new study reveals that plants and animals are remarkably similar in their responses to changing environmental conditions across the globe, which may help explain how they are distributed today and how they will respond to climate change in the future.
Is Niagara Falls a barrier against fish movement?
on March 24, 2020 at 1:00 pm
New research shows that fishes on either side of Niagara Falls -- one of the most powerful waterfalls in the world -- are unlikely to breed with one another. Knowing how well the falls serves as a barrier to fish movement is essential to conservation efforts to stop the spread of invasive aquatic species causing ecological destruction in the Great Lakes.
Pablo Escobar's hippos may help counteract a legacy of extinctions
on March 24, 2020 at 1:00 pm
When cocaine kingpin Pablo Escobar was shot dead in 1993, the four hippos in his private zoo in Colombia were left behind. Since then, their numbers have grown to an estimated 80-100 in the country's rivers. Scientists and the public alike have viewed the hippos as invasive pests that should not run wild in South America. Now a new study by an international group of researchers challenges this view.
Most bird feed contains troublesome weed seeds
on March 20, 2020 at 5:22 pm
Many millions of homeowners use feeders to attract birds. But a two-year study suggests there may be one unintended consequence to this popular hobby. Bird feed mixtures may be helping to spread troublesome weeds that threaten agricultural crops.
Sea otters, opossums and the surprising ways pathogens move from land to sea
on March 19, 2020 at 4:52 pm
A parasite known only to be hosted in North America by the Virginia opossum is infecting sea otters along the West Coast. A new study elucidates the sometimes surprising and complex pathways infectious pathogens can move from land to sea to sea otter.
Shedding light on how much carbon tropical forests can absorb
on March 19, 2020 at 1:02 pm
Tropical forest ecosystems are an important part of the global carbon cycle as they take up and store large amounts of CO2. It is however uncertain how much these forests' ability to take up and store carbon differ between forests with high versus low species richness. New research sheds light on this question aiming to enhance our ability to predict tropical ecosystems' strength as global carbon sinks.
Crop diversity can buffer the effects of climate change
on March 18, 2020 at 6:37 pm
Researchers found that farms with diverse crops planted together provide more secure, stable habitats for wildlife and are more resilient to climate change than the single-crop standard that dominates today's agriculture industry.
Beetles changed their diet during the Cretaceous period
on March 18, 2020 at 6:36 pm
Like a snapshot, amber preserves bygone worlds. Paleontologists have now described four new beetle species in fossilized tree resin from Myanmar, which belong to the Kateretidae family. As well as the about 99 million years old insects, the amber also includes pollen. It seems that the beetles helped the flowering plants to victory, because they contributed to their propagation.
Unraveling the puzzle of Madagascar's forest cats
on March 16, 2020 at 6:14 pm
Biologists have long wondered where Madagascar's mysterious wild cats came from. Now, new genetic evidence delivers an answer.
The naming of the shrew
on March 11, 2020 at 5:10 pm
Researchers have discovered a new species of shrew, which they have named the hairy-tailed shrew, or Crocidura caudipilosa.
Soldier ants reveal that evolution can go in reverse
on March 9, 2020 at 8:52 pm
Turtle ant soldiers and their oddly-shaped heads suggest that evolution is not always a one-way street toward increasing specialization.
