In hot water due to climate change, many ocean fish are moving to higher latitudes or deeper waters to find the conditions they need to survive.

These include lobster, black bass, and Atlantic cod, all of which have supported iconic fisheries along the Eastern seaboard of the United States. “Ocean animals are moving ten times faster than animals fleeing climate change on land,” says Rutgers University marine biologist Malin Pinsky, whose Rutgers OceanAdapt website enables visitors to explore changes in marine species distributions over recent decades. These range shifts are causing headaches for fishing fleets, which are forced to head farther out to sea or hundreds of miles further from...

Man’s best friend is being enlisted in efforts to detect the soil-born pathogen responsible for sudden oak death and other rapidly spreading plant and tree diseases.

Phytophthora is difficult to detect in nurseries, plant materials, and planting sites until it has done its damage. To develop early-detection options, H.T. Harvey and Associates are training a female cattle dog/border collie mix named Bolt to sniff out Phytophthora. Part of the Harvey Dog ecological-scent detection program, Bolt has accurately identified four species of Phytophthora in the lab. If her training in a natural setting is successful, Bolt could get to work helping minimize the spread of Phytophthora. Potential beneficiaries...

Options for Orphan Species

Off a bustling Delta highway, next door to a branch of the California Aqueduct, sprawls a tidy collection of shipping containers, humming pumps, and cylindrical tanks. Paved in cracked asphalt and encircled by chain link fencing, it resembles any number of light industrial sites at the margins of many communities. In fact, this resolutely artificial site is devoted to preserving a disappearing piece of natural California: the Delta smelt. “Our fish are a refuge population,” says Tien-Chieh Hung. Director of...
