Waters Lab

Laboratory Standard Operating Procedures

In this lab, we believe that science is real, love is love, Black Lives Matter, feminism is for everyone, trans rights are human rights, ants and flies are cool, and everyone is welcome here.

Cities power evolutionary divergence by accelerating metabolic rate and locomotor performance.

NSF Grant to support new Drosophila epigenetics-to-metabolism research

With funding from the NSF EPSCOR program and in collaboration with colleagues across the country, we’re embarking on a 4-year mission to investigate epigenetic mechanisms of thermal adaptation in Drosophila

Thermolimit respirometry analysis steps

Sample script for analyzing thermolimit respirometry data. Thermolimit respirometry analysis steps This page is designed to be a guide for members of our lab doing thermolimit respirometry. We have a protocol (see document on our lab Google Drive) for conducting the experiment and this is meant to help complete the analysis. So I’m assuming you’ve exported a drift-corrected .csv file from the main Expedata recording. We’ll get started by importing this file.

Interactive ggplot allometry with plotly in R

Plotting metabolic rate scaling data in an interactive way. Insect metabolic allometry data In a paper published in 2007, Steven Chown and colleagues compiled a large database of insect metabolic rates. The data demonstrated that insect metabolic rates scale hypometrically with their mass (larger insects have higher metabolic rates than smaller insects, but not proportionally as high; on a mass-specific or gram for gram larger insects are using a lot less energy than their smaller counterparts, both within and across species).

Respirometry notes 3/20/2021

Notes on setting up to do thermolimit respirometry. New aluminum chambers We had these respirometry chambers made by the ASU machine shop, based on the similar ones designed by Sable to use with their peltier-effect heating/cooling plate. The chambers are made from aluminum, have barbed fittings to attach tubing, there is a path through the top so that the incurrent air can thermally equilibrate, a cylindrical cavity to hold the insect, and two threaded caps which tighten onto an O-ring and which have glass windows to allow insertion of a pair of infrared emitter and detector.

Allometry with R and ggplot2

A simple guide to plotting a metabolic allometry figure with example scaling data and R code. This web page was created based on using the blogdown and Hugo packages to publish an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com. In the text below, you should be able to copy all of the code in the gray code chunks and paste it into a script file to replicate the results and figures in R on your own computer.
