Capuchino Seedeater Diversity

Final plate showing diversity among South American Capuchino Seedeater species to accompany paper by Dr. Leo Campagna published in Plos One this month. The recent Capuchino Seedeater biological radiation from the genus Sporophila, is a highly diversified group that evolved during the Pleistocene in Neotropical grasslands. It was really fun painting the different color combinations.
 

Maps for Living Bird Summer 2018 Issue

The summer issue of Living Bird magazine is out! I did the graphics for some interesting stories ranging from loons and lead fishing tackle to the amazing migration of the Amur Falcon. Also a feature on keeping hope alive for the Hawaii Iiwi. 

First shot is the conservation department article on the severely retracted range of the Iiwi and my map showing current range vs range in the 1800s. 

Second, a map showing the migration route of the Amur Falcon from breeding grounds in eastern Asia to wintering grounds in southern Africa. They fly 2,400 miles and to fuel up for this journey they stop in Nagaland to eat trillions of termites that erupt from underground colonies.

Firefly Infographic for New York Conservation Magazine

I designed and illustrated an infographic for New York Conservationist magazine's June 2018 issue, in collaboration with Cornell entomologist Cole Gilbert. This centrefold visualizes distinctive flash patterns of different species in New York.

Flashes serve as a dialogue between males and females, with the males doing the flying. Interestingly, the color of the flashes depends on the time of activity- with late flyers producing a green flash and early evening flyers making a yellow flash. For the online issue click here

Beachcomber book hits shelves

I created over 50 watercolor spots for the new Beachcomber's Companion Guide to Collecting and Identifying Beach Treasures written by Anna Marlis Burgard. This was such a fun project and collaboration. I was able to work largely from specimens that Anna sent from her collection. It's a great read, here's a quick synopsis from Chronicle's website below:

coverBeachcomber_JillianDitner.jpg
Breezy, inviting, and delightful—just like a day at the beach— The Beachcomber's Companion is a charming illustrated guide to collecting and identifying shells and other coastal treasures. Each of the entries includes fascinating descriptions, fun tidbits, and detailed artwork that makes it easy for readers to identify their own beach discoveries. A handy resource section offers tips on how to prepare before setting out on a shoreline adventure: from the beachcomber's commandments to must-have items for every beachcombing toolkit and advice on preserving shells. Awash with information and gorgeous watercolor illustrations, this is an essential companion for all who love the ocean's shore.

RGD Designer's Field Guide

Illustrations used for A Designer's Field Guide, a guide to RGD Membership, with a handy notebook for thoughts, ideas and general observations. The 64-page booklet describes the various aspects of being part of the Association, including information on the Certification Exam, all Programs, volunteer opportunities and benefits of Membership.

RGD Members receive a copy of RGD's 2017 Designer's Field Guide, designed by Forge Media + Design with printing sponsored by RGD Print Partner Flash Reprodutions and Paper Sponsor Huge Paper. Professional RGD Members that attended DesignThinkers received their copies at the Conference.

Weather and Climate Textbook Illustrations

I contributed the illustrations to the technical art program for Sheila Loudon Ross' Second Edition of the Weather and Climate Textbook, published by Oxford University Press. Released earlier this year, this introductory text features coverage of current climate change issues and new discussions of important topics to give students greater insight and understanding into processes that affect weather and climate worldwide.

Diagrams were illustrated using a combination of Adobe Illustrator and Photoshop.

Smithsonian Institution, Department of Entomology

For my internship term at CSUMB, I worked with staff illustrator Taina Litwak in the Entomology Department at the National Museum of Natural History in Washington, DC. During my time I created insect specimen illustrations for Entomologists conducting research on newly described species. 

Using the compound and dissecting microscopes, camera lucida and Photoshop painting techniques, each specimen was accurately depicted by working closely with scientists to ensure correct anatomy. This experience was key to expanding my knowledge of complex entomological anatomy. My illustrations will be included in a wonderful collection describing flea beetles of the Caribbean along with many other talented illustrators.

Interpretive Panel Design

Inspired by a documentary The Almendro Tree of Life, which can be viewed here, I wanted to create an interpretive panel to reveal the important link between these amazing trees and a species that relies on it - the Great Green Macaw.
