lakes – envirobites

Algal blooms aren’t a new environmental problem, but is climate change making them worse? In this study scientists use a new method to see how the occurrence and severity of algal blooms has changed in lakes around the world as the climate has been getting warmer.

Pharmaceutical and Personal Care Products Alter Lake Food Webs

July 12, 2019 Brittany Maule 0 Comments algae, emerging contaminants, lakes, water

The pharmaceutical and personal care products we use daily enter aquatic environments. Phytoplankton, or microscopic algae, are important pieces of the aquatic food chain. Phytoplankton exposed to pharmaceutical and personal care products in two Norwegian lakes responded quickly and dramatically – altering their community structure. The effects of these compounds on phytoplankton suggest these compounds have the potential to alter the food webs of entire aquatic ecosystems.

Work smarter and harder: a fieldwork fable involving the investigation of lake greenhouse gas emissions

“Are you sure this is the ramp?” my colleague, Dr. Jake Beaulieu asked the head field researcher, Adam Balz, as we drove up to the site.

The three of us took in the view of the crumbling asphalt inclined plane that disappeared into the lake. According to the map, this was the boat launch. But the usage of the lake had changed from allowing motorized craft to “paddle craft only” several years ago, and now the disused ramp was covered in layers of sandy sediment.

We can apply results from food web studies to understand how land-use and invasive species may force diet shifts in economically important fishes such as walleye.
