In recent years, Florida wildlife officials have been concerned the growing population of rhesus macaques living in Silver Springs State Park. They feared the nonnative animals were taking a toll on the region's ecosystem and had the potential to transmit diseases. But a new study by San Diego State University biologists proves otherwise.
In recent days, as temperatures increased in Minnesota and Wisconsin, millions of ladybugs crept out from hidden crevices to plague homeowners. Although these tiny insects were once considered cute, their huge swarms are causing more people to view them as mere pests.
Pathogen-carrying ticks are hitching rides from Central and South America on migratory birds.
A University of Delaware study shows that non-native plants have an impact on the diversity of insect populations. Their study sheds light on how homeowners are impacting local insect communities when planting their gardens and flower beds.
A recent eradication process removed 242 non-native arctic foxes from Chirikof Island in Alaska. The invasive species was originally introduced for fur farming but has since become a nuisance, threatening natural habitats and bird populations.
Africanized honey bees have been expanding northward in California since they were introduced in 1994. Because they are limited to warm temperatures, future climate change could expand their range even more.
Florida has become home to many invasive species that are threatening the Everglades. When non-native species establish themselves, it is harder to remove them. This puts an ecosystem's biodiversity at risk.
A species of wood ants observed in the North York Moors National Park, UK, are thriving in forests where non-native trees have been planted over the past 60 years. This suggests that we could help forest-dependent species rebuild their homes.
