About

We help organizations understand biological systems.

We do this through data and decision analysis, database design and software development.

What’s in a name?

Poisson is the French word for fish and the name of a statistical distribution of fundamental importance in population ecology.

Land Acknowledgement

We are grateful to live and work on the ancestral territories of the Blackfoot Confederacy (Siksika, Kainai, Piikani Nations) and the Tsuut’ina, Stoney Nakoda, Sinixt, Syilx, and Ktunaxa Nations as well as the ancestral unceeded territories of the Haida, Musqueam, Squamish and Tsleil-Waututh Nations and the homelands of the Metis Nation.

Shiny Upload App User Guide

We have created a document to guide users through the steps for submitting their data to Poisson via the shiny upload app. You can find the user guide at Shiny Upload App User Guide.

Shiny Upload App

We are pleased to announce that we can now efficiently deploy user-friendly web interfaces for clients to upload different types of data including punched excel workbooks, scanned field cards, photographs, logger downloads and GPS tracks.

Species Sensitivity Distributions App

The Species Sensitivity Distributions shiny app is a webpage for interactively fitting species sensitivity distributions to concentration data. The user is able to select more than one distribution and plot the individual fits.

Yield per Recruit App

The Yield per Recruit shiny app is a webpage for interactively exploring the effect of various fish population parameters on the schedule, stock-recruitment relationship and yield. The calculations are performed by the ypr R package, which also generates the plots and table.

Tidal Predictions App

The Tide Predictions shiny app is a webpage for visualizing and downloading tide height data. The tide heights are calculated using the rtide R package. Currently, predictions are available for 637 US stations.
