These files (.ply format) are surface meshes for the mandible and parasphenoid of the Permian fish Brazilichthys macrognathus. They were used to make comparisons with other Paleozoic fishes. These meshes can be opened in several programs (e.g., MeshLab; https://www.meshlab.net/).

GnRH Neuron Excitability and Action Potential Properties Change with Development But Are Not Affected by Prenatal Androgen Exposure. Jennifer Jaime, Suzanne M. Moenter eNeuro 29 November 2022, 9 (6) ENEURO.0362-22.2022; DOI: 10.1523/ENEURO.0362-22.2022
Data were collected to test theories advanced during a Contested Case Hearing to expand treatment capacity of the City of Brighton wastewater treatment facility. The lake historically developed nuisance blooms of cyanobacteria associated with excessive phosphorus and nitrogen limitation. The new wastewater treatment facility reduced phosphate discharge and provided increased concentrations of nitrate. A case study narrative describes the scientific and legal aspects of the case. Data collection and analysis pointed to the presence of a cryptic source of phosphorus income other than from the influent streams, possibly from undocumented septic waste discharges.
Archives at the Institute for Fisheries Research (IFR) hold records of thousands of lake surveys from the University of Michigan and Michigan Department of Natural Resources. The records contained in this dataset are jpeg images of the index card records from the IFR surveys. Images include the front of the card and when available, the back of a card. and Management Proposals Cards contain information for a lake and proposals for management strategies. Information includes present designation and change in designation, present game species, stocking suggestions, predator control, food increase suggestions, vegetation, shelters, spawning facilities, water level regulation, and other recommendations.

Images include the front of the card and when available, the back of a card. and Management Record cards show recommendations of management actions for each lake and then the record of actual management practices and results. Each action includes a date. Examples of management recommendations and actions include stocking, habitat management, regulation, and eradication.

Bottom Food Summary Cards report the samples from the bottom of the lake taken to look for possible food sources for fishes. This information includes the station number, area sampled, depth sampled, bottom substrate type, vegetation, and the organisms per sample. Organisms include round worms, flat worms, gastropods, molluscs, amphipods, water mites, and macroinvertebrates.
