The Forest Project
Examining the relationship between forest fragmentation -
resulting in a variety of different kinds of landscape patches - and species survival.
In support of the preservation of mature, intact forests,
by drawing attention to the beauty and intricacies of the minute within the grand,
and the interdependent, reciprocal relationships within these interwoven communities.

Class: Musci
Subclass: Bryidae Family: Mniaceae Genus: Plagiomnium Growth Form: Acrocarpus Identifying Features This moss, with vegetative stems trailing along the ground and capsule-bearing stems standing upright, intertwines to form loose, dark green tufts 3-6 cm tall. Leaves are 5-8 mm long, shiny green to yellow green, tongue-shaped, with rounded apex. Their midrib extends to a point beyond the leaf tip. Sharp teeth run from tip to base along margins having a faint border. Leaf corners extend down onto the stem, alternating in a growth pattern of two neat rows. Leaves cluster into rosettes only on the tops of upright stems. |
Habitat
This moss species grows in various locations within the forest: on soil, rotting logs, tree bases, rocks in shady swamp areas, and along streams. Growing on soil or rotting logs, you may discover Aphaenogaster picea wandering within.
Ecology
Interestingly, these two species are not not in competition for water. While water is all-important to the moss, this ant species regularly refuses liquids.

When finalized, this study will become one in a series of illustrations & natural history artworks that together tell a story of reciprocity
within a healthy forest community. The habitat scene and infographic below will also be included in this series.

“Trillium grandiflorum Seed Dispersal by Aphaenogaster picea Ants”
in Plagiomnium ciliare & Ctenidium molluscum forest floor mosses
During late summer/early autumn, in the ground mosses of mature, intact Beech-Maple forests of ne NA, Aphaenogaster picea worker ants are busy carrying Trillium grandiflorum diaspores back to their nest. When their larvae young feed on the elaiosomes they leave the seeds behind, undamaged. After feeding, the workers discard the seeds by casting them out of the nest or carrying them to underground middens.
|
Myrmecochory is seed dispersal by ants. Myrmecochorous plants produce diaspores, seeds with elaiosomes or external appendages, also known as “food bodies”, rich in lipids, amino acids and various other nutrients. These food bodies attract ants.
Myrmecochory represents a reciprocal or mutually beneficial relationship. While the ant larvae benefit from the rich food produced by the plants, the plants benefit by having their seeds carried farther away than they themselves can drop them, to a microsite that is made rich in nutrients by the ants and provides protection from predators. Here, a new plant colony is born! |

This scientific illustration was produced first with a crowquill pen and ink on Strathmore Bristol smooth 400 series paper, then scanned and overlaid with digital watercolour in Photoshop CS6 using a Wacom tablet & stylus. Also in Photoshop, labels and text were added, for the complete infographic presentation below.

The Forest Project . . . a work of indefinite boundary
Being the youngest organisms on this life-giving planet, we humans have much to learn from the interactions of all who came before. My intent is to continue gathering lessons of healthy community living and to translate them into visual story form. Through this means I hope to encourage deeper understanding as well as practical action, toward "a different relationship, in which people and land are good medicine for each other."
