Three new species of toads have been discovered living in Nevada's Great Basin in an expansive survey of the 190,000 square mile ancient lake bottom, report investigators.
Citizen science has revealed the spread of the invasive giant slug Limax maximus and its potential native predator in Japan, providing new insights into predator-prey dynamics between introduced prey and native predators.
Vast swaths of Pennsylvania forests were clear-cut circa 1900 and regrowth has largely been from local native plant communities, but a team of researchers has found that invasive, non-native plants are making significant inroads with unconventional natural gas development.
A study in fruit flies suggests that existing approaches to gene drives using CRISPR/Cas9, which aim to spread new genes within a natural population, will be derailed by the development of mutations that give resistance to the drive.
Mercury is a ubiquitous environmental contaminant that affects the health of birds and other wild animals.
A new study finds that tallgrass prairie restoration at a large Illinois preserve is working at a foundational level -- in the soil. Bacteria in the soil are recolonizing and recovering on their own to resemble soil found in remnant prairies. The study shows that a carefully managed restoration can produce successes even beyond easily-recognized plant and animal biodiversity.
Fish that migrate between freshwater and sea ecosystems play a multitude of ecological roles. In the centuries since Europeans first colonized the Americas, damming and other disruptions to river connectivity have greatly decreased the migration opportunities of these species. A new article outlines the effects of lost habitat and river connectivity for these crucial fish.
A new global analysis of forest habitat loss and wildlife extinction risk shows that species most at risk live in areas just beginning to see the impacts of human activities such as hunting, mining, logging and ranching.
Bornean orangutans living in forests impacted by human commerce seek areas of denser canopy enclosure, taller trees, and sections with trees of uniform height, according to new research. These orangutans are critically endangered, and despite intense conservation efforts, their numbers continue to decline. Additional habitat management strategies that account for their presence in forests affected by logging and other human activity are needed to ensure the species' survival.
Invasive plant species like seaweed can provide vital ecosystem functions in coastal areas where native habitats such as salt marshes and oyster reefs have severely declined. A new study finds that invasive species could be used to offset the loss of native habitats that provide storm protection, food production and other benefits to billions of people.
Researchers have improved their method of tracking species by using the biological material those organisms leave behind known as environmental DNA (eDNA).
Old World Sahara mustard is spreading rapidly through southwestern US deserts, smothering the native wildflowers that draw tourists to the region and disrupting the desert ecosystem. A new study is investigating when the invasion originated and what enabled Sahara mustard to adapt so successfully, to gain insight into how to stop it.
New biological information gleaned from the red vizcacha rat, a native species of Argentina, demonstrates how genomes can rapidly change in size. Researchers set out to study this particular species because its genome, or its complete set of DNA, is the largest of all mammals, and appears to have increased in size very rapidly.
Hundreds of potentially new species of fungi have been discovered in the deep coral ecosystem in the 'Au'au channel off Maui, Hawai'i. These mesophotic coral ecosystems are generally found at depths between 130 - 500 feet and possess abundant plant (algal) life as well as new fish species.
Ships play an unknowing but dominant role in introducing and dispersing tough-shelled non-indigenous organisms into new environments, suggest researchers.
A campaign to cut government rules is being conducted largely out of public view, often by hires with potential conflicts, an investigation has found.
In the first such global evaluation, biologists found more than 30 percent of all vertebrates have declining populations. They call for curbs on the basic drivers of these losses.
Scientists now know more than ever about the flies that attack monarch butterfly caterpillars, thanks to citizen science. Since 1999, volunteers participating in the Monarch Larva Monitoring Project have collected and raised more than 20,000 monarch eggs and caterpillars, and they've recorded incidents of those specimens being parasitized by fly larvae.
Oil spills not only have a direct impact on species and habitats, but may also set off a cascade of perturbations that affect the entire food web, new research finds.
The presence of the carp, a freshwater invasive species spread worldwide, is alarmingly reducing the populations of diving ducks and waterbirds, according to a study.
