Hurricanes are major disturbances that alter dramatically stream ecosystems. Here we looked at the stability and resilience trajectories of two small tropical streams following major hurricane impacts.

Alisotrichia (Hydroptilidae: Trichoptera) - a curious microcaddisfly that, as a larva, does not build a case until it is ready to pupate. Almost all Hydroptilidae make silken cases, but Alisotrichia has a free-living larva and inhabits fast flowing habitats.
This specimen is from Puerto Rico.

The Erie Canal, opened 200 years ago, transformed trade and the United States – and also ecology. It cut freight costs by 90% but also introduced invasive species like sea lampreys to the Great Lakes, devastating fisheries.
