The scalloped hammerhead (Sphyrna lewini) is the shark most frequently landed in Guatemalan artisanal fisheries. From 2017 to 2023, fishery-dependent monitoring recorded 10,000 individuals across three fishing communities. Neonates represented the largest proportion (n = 5860), followed by young of the year (YOY, n = 3929) and significantly fewer juveniles (n = 183) and adults (n = 28). Seasonal patterns were evident, with neonates (84%) and YOY (67.5%) peaking between May and August. The data suggest that neonates and YOY are prevalent seasonally and annually in the three coastal areas.

Rice stripe virus disease is one of the most devastating diseases of rice () in East Asia. The causal virus, Rice stripe virus (RSV), is persistently transmitted by the small brown planthopper (, SBPH). Since there is no effective treatment once rice plants are infected with RSV, it is crucial to prevent RSV infection in rice to minimize the damage.

Copper (Cu) stamp mill mining in North America from the early 1900s produced a pulverized ore by-product now known as stamp sands (SS). In a mining operation near the city of Gay (Michigan, USA), SS were originally deposited near a Lake Superior beach, but erosion and wave action have moved many SS into beaches and reefs that are critical spawning and nursery areas for native fish (e.g.
