nestling-growth-app 0.1.4

An interactive Dash app to analyze nestling growth using biological models

🐣 Nestling Growth App

The Nestling Growth App is a web-based tool designed for ornithologists, ecologists, and researchers working on nestling development. It allows users to visualize and model growth metrics such as weight, wing, and tarsus length using classic biological growth functions.

• Logistic
• Gompertz
• Richards
• Von Bertalanffy
• Extreme Value Function (EVF)

This app is ideal for ecologists, ornithologists, and conservation biologists looking to model nestling growth patterns, compare model performance using AIC/BIC, and export results seamlessly.

✨ Features

✔ Upload CSV files with growth data
✔ Select variables dynamically (e.g., weight, wing, tarsus)
✔ Automatically fit multiple growth models and visualize the best fit
✔ Export graphs and model results in CSV and PNG formats
✔ Interactive UI powered by Dash and Plotly
✔ Dual-tab layout:

• Weight Analysis
• Wing & Tarsus Analysis

Input Format

The uploaded CSV should contain at least: A day column (e.g., Day, Age, Month) At least one of:

• Weight
• Wing
• Tarsus

Output

Graphs with observed and fitted curves A table comparing models by:

• PNG graphs ready for publishing 300dpi
• AIC/BIC
• Parameters
• Growth rate k
• Inflection point T
• ΔAIC

Examples

You can access to the folder: data In order to have some previous data to test and learn from.

📦 Installation

You can install the app globally via pip:

pip install nestling-growth-app

Once installed, run it with:

nestling-app

✅ Option 2: One-Line Install (recommended)

Just open your terminal (or Anaconda Prompt) and run:

pip install git+https://github.com/jorgelizarazo94/NestlingGrowthApp.git

Then launch the app with:

nestling-app

It will open on: http://localhost:8050

Option 3: Install in a Conda Environment (clean setup)

conda create -n nestlings python=3.9 -y
conda activate nestlings
pip install git+https://github.com/jorgelizarazo94/NestlingGrowthApp.git
nestling-app

Option 4: Clone the Repo and Run (for development)

git clone https://github.com/jorgelizarazo94/NestlingGrowthApp.git
cd NestlingGrowthApp
pip install -e .
nestling-app
