Observers believe both came here by “piggybacking” on exotic plants brought in by the horticultural sector. Read more at straitstimes.com.

Experts raise concerns after observing unprecedented change in species: 'It shouldn't be here'

Rising global temperatures have contributed to unpredictable weather events, but one constant is that wildlife is doing its best to adapt to the changing climate. Songbirds that used to migrate to warmer climates during winter have been spotted in Maine year-round, as the state experiences shorter and milder winters, Maine Public reported.  What's happening? Over half of the more than 650 breeding bird species of North America are migratory, acc…

2 aggressive invasive fish are both living in a Maine river. Scientists don’t know what will happen.

The newcomers are making it difficult for the native species to use the river for their traditional feeding grounds.

Lake ice is melting exceptionally early this spring. For many fish species, the long open water season can be problematic.

Climate change coupled with migration of non-native species pose threat to Northwest fish

(Photo by Jonny Armstrong, courtesy of Oregon State University)Some already threatened cold-water fish species in the Northwest will not only face shrinking habitat from climate change but will face growing pressure from invasive fish species fleeing their own warming and dwindling waters, according to modeling from researchers at Oregon State University. The findings were part of a study pu…

Water Year Impacts Assessment shows relief from drought, help for migrating salmon

Unexpected relief for the Pacific Northwest's drought has come from short-term cooler, wetter conditions, which also helped migrating salmon, according to the just-release Pacific Northwest Water Year Impacts Assessment.
