Overview
The Extech ExStick Chlorine Meter features a unique flat surface electrode that conducts direct total chlorine readings. The range is 0.01ppm to 10ppm, and the measurements are unaffected by the color or turbidity of the sample. The memory stores, tags, and recalls up to 15 readings and calibrations. The 2000 count LCD simultaneously displays ppm of total chlorine and temperature plus analog bargraph indicator.

The Birds and the Bees: Understanding the Diversity of Pollinators
Pollinators of all shapes and sizes are vital to ecosystems around the world. From the wide array of food people eat to the diversity of life around the planet, life would be very different without them. Pollinators are organisms that help carry pollen from one plant to another, and over 350,000 species can be found worldwide, according to The California Department of Fish and Wildlife . With the strong relationship between plants and pollinators, losing either would have detrimental impacts on ecosystems. 
 
 Over millions of years, both plants and pollinators have evolved alongside each other and formed unique adaptations that allow them to work together, expediting and enhancing the process of pollination.

The eight main Hawaiian Islands are made up of 15 volcanoes, six of which are active as of 2023 . Many locals live on or near an active volcano, making the monitoring and understanding of volcanic activity a core issue of public safety on the islands. Organizations like the Hawaiian Volcano Observatory (HVO) have spent decades monitoring the islands’ volcanoes to protect the public, develop a deeper understanding of the islands’ volcanos and forecast eruptions whenever possible. 
 
Even those who live away from edifices like Mauna Loa often have connections to the people living near the volcano.

From crystal clear alpine lakes to muddy rivers and boggy swamps, water transparency is an easily observable water quality parameter to anyone who takes a few moments to peer into the (sometimes) murky depths. Water transparency varies dramatically based on the location of bodies of water among different watershed environments, but it can also change quickly due to a variety of internal and external factors. 
 
 At Miami University (OH), the Global Change Limnology Lab explores the many ways that water transparency impacts aquatic ecosystems. Operational for nearly 20 years, the lab trains undergraduate and graduate students and has conducted work from the midwest Great Lakes to Alaska, South America and New Zealand. 
 
 The Global Change Limnology Lab, headed by Dr.
