Four Examples of Nest Predation by Rats (Short)

Black rats were unintentionally introduced to Hawai’i in the late 1800s, most likely as hitchhikers on trading vessels. Since their introduction, they have disrupted native ecosystems by destroying native plants, eating native arthropods, and depredating bird nests. Black rats have contributed to population declines and species extinctions of Hawaiian forest birds, and

Geneticist extracts DNA from samples to detect fungal pathogen

Geneticist, Kylle Roy, extracts DNA from samples to detect Ceratocystis, a fungal pathogen that causes Rapid Ohia Death. Samples have been acquired using aerial spore traps, by collecting wood shavings from ohia trees, or by collecting frass (excrement) of wood-boring beetles.

Resurrection Bay on August 8, 2016. The water appeared calm in the shelter of the inner bay, but closer to the entrance, swells coming in from the Gulf of Alaska were breaking on a small beach where the three boaters had capsized.

Air sampling station on the Hāmākua Coast on the island of Hawai‘i

A trap designed for collecting airborne particulates deployed on the Hāmākua Coast of the island of Hawai‘i. The traps appear to be an effective method for monitoring airborne fungal spores as hundreds of fungal taxa were identified from a handful of samples screened by second generation sequencing.

Wood boring beetle tunnels inside of an ‘ōhi‘a log. Researchers are investigating if the spread of beetle frass (excrement) is a pathway for movement of a fungus that causes Rapid ‘Ōhi‘a Death.
