Welcome to my website. Below find posts with interesting links or explore the rest of my website to see my teaching and research interest. I am interested in the following topics aquatic ecosystem ecology; invasive species; technology and aquatic ecosystems; biogeochemistry; lake metabolism; human impacts on streams, rivers, and lakes.
This past year, Livi Carlen and Luke Barnell (SUNY New Paltz Graphic Design ’19) worked with my lab to create a short documentary titled “Algal Growth in Freshwater Lakes.” We detail how the synergy of climate change and excess nutrients could be increasing algal blooms in our freshwater lakes. Considering the importance of lakes in providing goods and services to humans, this topic is incredibly important to keeping our lakes healthy. See the short above or linked here.

Heather Wander (Biology ’18) just recently graduated after a long and successful time in my lab. Just to highlight some of her accomplishments, Heather presented her research at multiple national meetings including the Ecological Society of America 2017 meeting in Portland, Oregon, the 2017 Global Lakes Ecological Observatory Network all-hands meeting at the Mohonk Mountain House and the 2018 Global Lakes Ecological Observatory Network all-hands meeting at Rottnest Island just off the coast of Perth, Australia. Heather is also a co-author on three manuscripts stemming from her research (one paper is accepted in the peer-reviewed journal Freshwater Science, one is submitted to the peer-reviewed journal Inland Waters) and the lead author on a manuscript examining the vertical distribution of zooplankton in lakes with differing food webs.
In 2011, two large tropical cyclone passed over northeastern North America. We examined the effects of the large storm systems had on lakes along the storm tracks from the Atlantic coast inland through our region. We collected data on the thermal stratification and ecosystem metabolism. We published these results in a 2012 paper in Environmental Science and Technology (Klug et al. 2012). We have now published the data for anyone to explore or further analyze. It is available through the Environmental Data Initiative at the link below.

Here are two new data publications out of the Mohonk Preserve Daniel Smiley Research Center (DSRC) in collaboration with my lab. The publications came about as a result of the NSF-funded internship I co-hosted along with the DSRC. This internship is part of the Environmental Data Initiative (EDI), a web-based data portal and data infrastructure program that was designed to help support the information produced through environmental research. Our EDI intern, Vanessa Morgan (SUNY NP student), received training on-site at EDI in the beginning of the summer before returning to New Paltz to start working with the DSRC data. Data from the precipitation depths and pH publication are published in Richardson et al. (2018, see Publications).

We recently held our 4th annual NE GLEON meeting at the Cary Institute, Apr 2018. This conference brings together researchers and students from all over northeastern North America to present science, discuss professional development, plan experiments, and more. Three of my SUNY New Paltz research students, Kayla Reid (Biochemistry ’18), Hailee Edwards (Biology ’18), and Heather Wander (Biology ’18) wrote a post about it for the GLEON blog (click here for the post).
Paul Hanson, GLEON co-chair, said “The blog highlights major landmark achievements over its course of three years and share experiences of the juvenile limnologist whom we will see in the near future representing GLEON and managing lake resources in the world. I hope and bet that you’ll enjoy reading the blog written by Hailee Edwards, Heather Wander and Kayla Reid (undergrad students)…”

I am the lead author of a new paper titled “Watershed management and underlying geology in three lakes control divergent responses to decreasing acid precipitation,” which was published in the journal Inland Waters. The paper was a collaborative effort between SUNY New Paltz and the Mohonk Preserve. The manuscript included five SUNY New Paltz undergraduate co-authors, all funded through SUNY New Paltz Research, Scholarship, and Creative Activities (RSCA): David Charifson (Biology ’13), Bobbetta Davis (Biology ’16), Matthew Farragher (Environmental Geochemical Sciences ’16), Bryan Krebs (Biology ’15), and Brian Wilcove (Biology ’16).
We examined patterns of acidity in rain and three Sky Lakes on the Shawangunk Ridge (Lake Minnewaska, Lake Awosting, and Mohonk Lake). We found that rain water is improving over the last 40 years with decreasing acidity. However, the three lakes have had very different responses despite being close together. Lake Awosting is improving slowly – this matches decreasing rain acidity directly. Mohonk Lake has always been close to neutral because of exposed shale under the lake. Lake Minnewaska gone from acidic to almost neutral because of improving rain acidity and eroding shale recreational trails around the lake. In these lakes and around the world, the rate of recovery from acid rain can affect the return of acid-sensitive freshwater organisms.

I was a co-host and co-chair of the planning committee for the 19th meeting of the Global Lake Ecological Observatory Network. ~240 scientists from 31 countries around the world gathered at the Mohonk Mountain House November 2017 to discuss global lake science. See a description of the meeting here:
Led by Dr. Catherine O’Reilly (Illinois State University), a group of collaborators and I published a paper titled “Using large data sets for open-ended inquiry in undergraduate science classrooms” in the journal BioScience. This paper details Project EDDIE (Environmental Data-Drive Inquiry and Exploration), a project aimed at getting large and complex data sets into undergraduate classrooms to give them valuable data-analysis skills through . The collaborators developed a series of free modules that can be adapted or adopted in a range of courses, class sizes, and institutions. The paper abstract can be viewed here and the full article can be viewed here.
