Many Hands Make a Mitey Webpage

I would like to announce the completion of a massive update of the UBC Biodiversity Research Center Mites and Microarthropods Webpage.

The major task of the update was adding 158 new microarthropod species to the database that were identified as part of my Masters research and the research of Youhua Chen and Jiichiro Yoshimoto. This task involved drawing and photographing all of these species in 3 views (dorsal, ventral and side), as well as deciding what menu or grouping of similar looking arthropods they should fit into. The website looks amazing thanks to the drawing and photographing talents of Pamela Matute, Dorota Niewczas and Michael Millar. There are a few of my drawings and photos featured as well.

In addition to adding the new species, a major re-organization took place in which new groups or categories of mites were created and others dissolved. Some of the pages were also re-designed. All the changes sought to make the webpage simpler to update, the mites easier to find, and the categories more taxonomically relevant. With the help of web programming wizard Kelvin Kou we also brought the webpage into the 2010’s by updating the code to CSS format. He incorporated many changes into the code that will allow the page to be viewed on a smart phone and by blind users.

This was a commendable effort to all who helped in process. I think the result is beautiful. The page still heavily reflects Derek Tan’s original design, to whom I am greatly indebted for making a great page to start with and showing me pointers along the way for how to take photos, edit the picture menus in photoshop, and update the codes in dreamweaver. Many thanks to all. I hope you enjoy using the site!Image

Mite drawings for the webpage

We have been working to update the lab mite webpage (http://www.zoology.ubc.ca/~srivast/mites/index.html) with the new morphospecies we found over the last year. I thought I would share some of the beautiful mite and springtail drawings that were done my work-learn student, Pamela Matute.

Beautiful Soil Mites

I recently finished sorting the samples for my Masters experiment! The project is investigating how dispersal rate and synchronicity of disturbance across the landscape influence biodiversity and community resilience to disturbance. This is a photo of the experimental landscapes I established with different levels of connectivity and different disturbance regimes:

It took five months to sort the 120 samples. We counted 29,912 microarthropods (mites and springtails) in total. I will post more information on how many species we found as I analyze the data. I would like to thank Rebecca Taves and Pamela Matute for all their help sorting the samples and Youhua Chen and Jiichiro Yoshimoto for their help with the field aspects of the study.

In celebration of this accomplishment, I would like to share a video I created with my friend Gabriel Collins that showcases some of the mites and springtails I was working with. It is an abstract piece set to a soundscape we generated using objects around the house. I think it captures the beauty of these mysterious creatures and the great expansiveness of the time I spent admiring them under the microscope.

New Year, New Species for the library

In time for the New Year, we have completed sorting the mite samples for our collaborative experiment on regional biodiversity and resilience. This means that we can start getting some answers by data analysis! It also means I can start sorting the samples from my Masters research! This is all very exciting news. To celebrate this change of focus with the New Year, I would like to share some photos of some interesting new species that we have added to our mite library through the collaborative experiment. Please enjoy.

Completed Experiment!-

I completed my 6-month long experiment this week and figured this accomplishment deserves a blog entry!

The moss was collected in May and carved out into two-patch metacommunities with different levels of connectivity.

In May and August we subjected select patches to Tulgren funnel extraction (which removes a bunch of the mites and collembolans) for  synchronous and asynchronous disturbance treatments.

Finally, in November we sampled all 168 patches by putting them through Tulgren funnel extraction. Now, just another 6 months sorting mites under the microscope and I will have my data for my Masters thesis!

Many thanks to all the people that have helped make this experiment possible. I was on crutches when setting up, so it literally would not have been possible to start this experiment when I did without many of the following people’s assistance:

– Olga Lansdorp – official driver and field hand extraordinaire

– Jiichiro Yoshimoto – field and lab helper, moss waterer

– Youhua Chen – field and lab helper, through set-up and all 3 extractions

– Seane Trehearne – Totem field contact

– Rebecca Taves – helper for final extraction and take-down, skilled mite sorter

– Pamela Matute – helper in final extraction and take-down, mite sorting whiz

Finally, much thanks to Diane Srivastava for guidance and for providing me with so much help!
