Nitrogen can present a dilemma for farmers and land managers.

Latest satellite images reveal a new 100-square-mile iceberg emerging from Antarctica’s Pine Island Glacier. The calving event did not come as a complete surprise, but is a troubling sign with regards to future sea level rise.

Certain marine species will fare much worse than others as they become more vulnerable to the effects of climate change, a new UBC study has found.

Researchers have found that three common species of Vibrio bacteria in Chesapeake Bay could increase with changing climate conditions by the end of this century, resulting in significant economic and healthcare costs from illnesses caused by exposure to contaminated water and consumption of contaminated shellfish.

Unusually warm ocean conditions off the Pacific Northwest in the last few years led anchovies, sardines and hake to begin spawning in Northwest waters much earlier in the year and, for anchovy, longer than biologists have ever recorded before, new research has found.

Reducing tourist consumption of reef fish is critical for Palau’s ocean sustainability, finds a new UBC study that suggests other small island nations might also consider adopting this strategy.

Climate change is expected to lead to sharp declines in Palau’s reefs, and this new research suggests that the best tourism management strategy includes a more than 70 per cent reduction in the amount of reef fish eaten by visitors. These findings are relevant for sustainable development for other small island developing states that are likely to feel a significant impact from changes to the ocean.

A deadly amphibian disease called severe Perkinsea infections, or SPI, is the cause of many large-scale frog die-offs in the United States, according to a new study by the U.S. Geological Survey.

Frogs and salamanders are currently among the most threatened groups of animals on the planet. The two most common frog diseases, chytridiomycosis and ranavirus infection, are linked to frog population declines worldwide. The new study suggests that that SPI is the third most common infectious disease of frogs.

Researchers have discovered a new class of enzymes in hundreds of bacterial species, including some that cause disease in humans and animals. The discovery provides new insights into how bacteria invade their hosts. The research appears this week in Nature Communications.

Human activities could trigger an altered pattern of evolution similar to what occurred 66 million years ago, when a giant asteroid wiped out the dinosaurs, leaving birds as their only descendants. 

To find out what works best for reestablishing tropical dry forests, the researchers planted seedlings of 32 native tree species in degraded soil or degraded soil amended with sand, rice hulls, rice hull ash or hydrogel.
