Eukaryota Tree of Life (Bauldauf 2003)
four divisions in two kingdoms
What are Macroalgae?
![Page 3: Janet Sullivan and Chris Neefus University of New Hampshire](https://reader035.fdocuments.net/reader035/viewer/2022062323/568152b0550346895dc0d374/html5/thumbnails/3.jpg)
What are Macroalgae?
Rhodophyta (Red Algae) - 6,300 species in 10 orders
Chlorophyta (Green Algae) - 4,300 species in 15 orders
Charophyta - 3,500 species in 8 orders
Phaeophyta (Brown Algae) - 2,000 species in 18 orders

How are they important?• Foundation of aquatic ecosystems – provide food, shelter and
substrate for other organisms
• Maintain nutrient balance in aquatic ecosystem and produce oxygen
• $7.4 billion industry as human food, phycocolloids, pharmaceuticals
• Sensitive indicator of environmental changes in aquatic ecosystems

What is the Macroalgal Herbarium Consortium?
• 49 institutions in 26 states and U.S. possessions
• 1.2 million specimens in collections ranging from 100 to 200,000
• Project goal is to digitize (image, database, georeference) all of them

Workflow – Step 1
• Any pre-digitization curation
• Barcode placement
Step 1 – Any pre-
digitization curation
accomplished
Step 2 – Specimen is
barcoded and skeletal label data captured in an Excel file
(or .csv)
Step 3 - High resolution
image captured
Step 4 - Image and label data uploaded to MHC Portal
Step 5 – Additional label data
transcribed from within the portal
Step 6 – Specimens
georeferenced from within the portal

Workflow – Step 3High-Resolution Image Captured
• Lightbox/copystand• 21 to 36 megapixel camera• Camera Control Software• Adobe Lightroom (white balance, tone
curve adjustment, .jpg & .dng export)
