Higher Early Marine Mortality of Steelhead Associated with Releases of Hatchery Coho Salmon but Not Chinook Salmon

Marine and Coastal Fisheries, Volume 14, Issue 6, December 2022., 2022
Abstract Understanding the drivers of mortality during critical life history periods is an important part of increasing our capacity to rebuild depressed salmonid populations. For threatened steelhead Oncorhynchus mykiss in Puget Sound, Washington, early marine predation has been implicated as a key source of mortality.

Reducing the blue spectrum of artificial light at night minimises insect attraction in a tropical lowland forest

Insect Conservation and Diversity, Volume 14, Issue 2, Page 247-259, March 2021., 2021
Over 15 000 insects (18 orders) were captured across three lamp types emitting different spectra of light in a Peruvian Amazon forest previously naïve to artificial illumination. White 3000 K LED lamps attracted far more insects (morphospecies and individuals), including groups containing important disease vectors, than yellow and amber‐filtered 3000 K
