What’s driving changes in cod spawning grounds: climate or fishing?

Northeast Arctic Cod perform seasonal migrations from their feeding grounds to their spawning grounds. Recent evidence suggests that the distribution of cod between spawning grounds is changing. Two hypotheses have been proposed to explain why fish spawning grounds are changing: climate and fishing pressure. In order to determine which of these hypotheses may be the driving force in changing Northeast Arctic Cod populations, a team of scientist from Europe investigated fishery data from 2008-2016. Their results suggests that climate is driving changes in the distribution of Northeast Arctic cod spawning grounds.

Burning Desire to Forage

During the fall of 2018, California had some of the worst and deadliest fires to date, with devastating costs to human communities. Communities of plants and animals are also greatly impacted by fires. But how does wildlife respond to wildfires? Burns alter the environment and open up new habitats allowing smaller shrubs to recolonize in areas that were dominated by tall trees. A recent study in Oregon suggests that elk utilize a wide array of habitats and that burned forests are critical areas for food for many herbivores.

Soil in the Succotash Marsh, Rhode Island: Coring for clues to past coastal storms

When you think of a saltmarsh, what comes to mind? Maybe a place that smells bad and you prefer to avoid? A place to fish? Turns out, salt marshes hold clues to the past. Scientists along the East Coast of the United States, for example, can use the information in salt marsh soils to reconstruct past storms and determine the past sea levels. As scientists in Rhode Island, we were able to easily try and replicate the findings of a previously published study from the Succotash Marsh also located in Rhode Island.

Climate change could make your beer dear

Apart from being popular beverages in the world, do you know what the common link between beer and coffee is? Both may be affected by climate change. While we already know that climate change will impact coffee, a new study published in Nature Plants has established that beer is also under threat. Rising temperature and drought due to climate change can hit the beer supply hard all over the world and make beer more expensive.

Timing is Everything: Sockeye Salmon Migration on the Skeena River

For most salmon to complete their life cycle, juveniles must migrate out to the ocean as “smolts”. They are then able to grow quickly by taking advantage of marine food sources, before they return as adults to spawn in the river where they were born. With climate change affecting environmental cues and conditions, the timing of their migration might not match up to the availability of crucial food resources, which could reduce smolt survival. Will this phenomenon affect the Skeena River populations of Sockeye Salmon? Read on to learn more!

Nature vs. Nature or Engineering? The Case of Coastal Resilience

Coastal flooding has been a problem for as long as civilization has settled along the coast. During that same time civilization has been impacting natural features that would otherwise help mitigate this problem. There are two schools of thought in combating coastal flooding today: installing conventional engineering solutions and bringing back natural barriers. There are pros and cons to both strategies, but it really boils down to cost, space, and unintended consequences. In our opinion, nature should be used to fight nature. Read the article and decide for yourself!

The resilience of coastal wetlands – an optimistic look to the future

Loss estimates for coastal wetlands by the end of the century are severe. Coastal communities depend on these critical systems for the services they provide. With rising sea levels and encroaching human populations, the fate of coastal wetlands remains uncertain. However, a new study suggests that there is hope for these habitats even if the direst rates of sea-level rise occur. As long as coastal wetlands are given space to build upwards and migrate inland, we could preserve these habitats and the benefits they provide.
