LI-COR PAR sensors detect light waves to aid aquatic ecosystem research

Understanding how the sun’s rays fuel phytoplankton or plant growth may prove valuable to understanding an aquatic ecosystem. A pair of sensors from LI-COR can help researchers studying algal blooms and aquatic vegetation by measuring how much light enters underwater environments. Sitting below the surface, the LI-192 flat-lensed photosynthetically active radiation sensor and the LI-193 spherical PAR sensor measure light waves striking their silicon photovoltaic detectors.  They sense light wavelengths between 400 and 700 nanometers, which is the ideal range for photosynthesis. Dave Johnson, a LI-COR product manager for the LI-190 series, said the sensors’ individual designs make them ideal for different applications.

Ohio State greenhouse nurtures 'fruit fly of the plant world'

The Arabidopsis Biological Resource Center at Ohio State University was established in 1991 with funding from the National Science Foundation. Part of the center’s job is to meet demand for seed of the arabidopsis plant, which is widely used for genetic modeling. “A lot of the plants we’re growing are for seed production,†said Joan Leonard, greenhouse coordinator. “Arabidopsis is a good example. We call it the ‘fruit fly of the plant world,’ and it takes about six to eight weeks to go from seed to plant.†Arabidopsis is one of the many plants that will benefit from a new LI-COR PAR sensor being installed on campus. It will help manage light schedules for greenhouse plants.

Acidification May Ease Struggle to Survive for Herring Larvae

Survival in the ocean is no easy task, especially for ichthyoplankton, the eggs and larvae of fish. For most, including herring larvae, once they're released into the water, they're on their own, with survival as their sole goal. Climate change is making that goal more difficult to obtain for many species, but the changes to the marine atmosphere that come along with a warming climate are complex, and they affect various species in different ways. Scientists are still trying to research what some of those differences might look like. Struggle for survival Ichthyoplankton are vulnerable to predators, of course, but they are also highly sensitive to their environment. This means changes in dissolved oxygen levels, temperature, and pH can all be dangerous to fish eggs and larvae.
