Climate change coupled with migration of non-native species pose threat to Northwest fish
- Non-Native brown anole lizards and greenhouse frogs have established populations in various locations across Singapore by 2025.
- These species likely arrived through exotic plants imported by nurseries, with brown anoles first recorded in 2012 at Gardens by the Bay.
- Brown anoles are found in urban and artificial habitats such as Marina Bay, while greenhouse frogs have widespread breeding populations including nature reserves.
- Experts noted brown anoles and greenhouse frogs “can spread rapidly” and are “potentially invasive,” but current evidence shows no significant impact on native ecosystems.
- Authorities including NParks monitor these species and encourage public efforts to avoid releasing non-native pets while assessing ecological risks through ongoing research.

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…
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.
