Anglers in South Florida are catching fewer bonefish. FIU scientists believe answers could be found in Cuba.

Bonefish eggs float in the ocean for two months before they settle in nurseries. Models suggest spawning bonefish in Cuba may supply South Florida’s nurseries with eggs. If true, that means sustainable fisheries here may rely on sustainable fisheries there. Knowing what fisheries look like in underdeveloped areas like Cuba could help guide restoration efforts.

On farms across Africa, a seemingly innocuous brown and beige caterpillar is waging a silent war, devastating rural incomes and posing a major threat to the continent’s food supply. In just two years, the so-called fall armyworm has colonised three-quarters of Africa, according to the British-based Centre for Agriculture and Biosciences International (CABI).

As sharks disappear from key locations, scientists are using environmental DNA to find a small number that may actually be hanging on.

Years of visual surveys have left scientists worried that some species completely disappeared from areas where they were once abundant. An international team of researchers has used a revolutionary technology to retrieve fragments of DNA from shark skin, excretions and blood in the water to determine that somewhere in the area, these missing sharks still reside.
