Tools for Organismal Research
Our goal is to create open-access tools that enable researchers to investigate a range of molecular, organismal, and evolutionary biology questions while maintaining a firm commitment to biological diversity in research organisms.
Behavior
Short heading goes here
We developed a Course Undergraduate Research Experience (CURE) utilizing Caenorhabditis elegans chemotaxis assays to test how natural products are detected by heterospecific nervous systems. These experiments focus on ant-derived compounds and can be conducted in an undergraduate laboratory course, where new insights into interspecies interactions can be generated through genuine research experiences in a classroom setting. This assay is used in BIO161: Organismal Biology Lab and has resulted in several peer-reviewed publications with all students as co-authors. PMIDs: 38596360, 37008729, 32550506 Protocol
Home Security Cameras for Ectotherm Behavior
Reliably capturing transient animal behavior in the field and laboratory remains a logistical and financial challenge, especially for small ectotherms. Here, we present a camera system that is affordable, accessible, and suitable to monitor small, cold-blooded animals historically overlooked by commercial camera traps, such as small amphibians.
This setup was published by Goolsby et al, Home security cameras as a tool for behavior observations and science equity. Preprint DOI: 10.1101/2023.04.17.537238
You can find instructions for the setup in multiple languages on our GitHub and instructions on adjusting the focus of Wyze cameras in this protocol.
A Simple Phototaxis Assay for Aquatic Larvae
Phototaxis assays are utilized throughout neuroscience research to measure exploratory behaviors and visual capabilities. Here, we detail a simple and low-cost phototaxis assay for aquatic larvae. This assay is useful for behavior assays in laboratory settings and undergraduate teaching laboratories where students can gather data in real-time in a relatively high throughput manner.
This assay is published in Butler JM, et al. 2024. Tadpoles rely on mechanosensory stimuli for communication when visual capabilities are poor. PMID: 38851558
This assay was used in a Course Undergraduate Research Experience (CURE) and published with all undergraduate students as co-authors in Adebogun GT, et al. 2023. PMID: 36824381.
Poison Frog Tadpole Ethogram
Tadpoles display a rich array of behaviors. This ethogram was developed and illustrated by Dr. Julie Butler and is available as supplementary materials in Butler JM, et al. 2024. Tadpoles rely on mechanosensory stimuli for communication when visual capabilities are poor. PMID: 38851558

Tissue-Specific Expression of Plasmid DNA
Expressing exogenous genes with temporal and spatial specificity is a challenge with unusual research organisms. Here, we detail how to express exogenous genes from the electroporation of plasmids into the brain and muscle of poison frog tadpoles. This protocol is useful for expressing fluorescent reporters and other genes of interest.
This protocol is published in Delia, et al. 2023. Tissue-specific in vivo transformation of plasmid DNA in Neotropical tadpoles using electroporation. PMID: 37590232.
Using Morpholinos to Knockdown Proteins
Knocking down the abundance of proteins of interest is important for functionally testing their role in biological processes. Here, we detail how to use morpholinos to knock down protein abundance in tadpole brain tissue. We also present a relatively inexpensive semi-quantitive dot blot method for assessing protein knockdown. This manuscript is currently in revision, but the protocol is already available on protocols.io. Ludington SC, Butler JM, Golde C, O'Connell LA. 2023.
