Llano Estacado

April 13, 2008

Canyons that look like gentle hills when flying 35,000 feet overhead are, in fact, beautiful when seen up close while camping and hiking. These scenes are in the Llano Escatado of west Texas, April 2008.

Signs of Spring

Lime green leaves emerge and more plants begin to bloom….a few images as winters dies out and spring emerges, moving about 25 – 30 miles per day from south to north (so they say)…

No effusive commentary here…just random images I shot from the north side of Spring Creek recently.

Left to Right: reflection from Spring Creek, bark beetle tunnels, sunset, poison ivy on hackberry tree, fossil-bearing strata along the creek, raccoon tracks.

More Trout Lilies

March 1, 2007

These images of Trout Lilies (Erythronium albidum) were taken on private property from Feb. 24-Feb. 28, a undisclosed location north of Spring Creek Preserve. The rich woodland habitat for these beauties needs to be saved for future generation from development as well as invasive species located not too far from them. Alien species such as japanese honeysuckle, japanese privet, english ivy, nandina, and monkey grass threaten woodland habitat as well as native plants and animals.

Winter Afternoon Light

February 21, 2007

This time of year the late afternoon sun shines unimpeded through a leafless forest onto a vertical stream bank and backlights the current with a golden reflection …. (Canon Powershot A-80)

Trout Lilies and Ants…

Trout lily seeds contain a structure on the outside of the seed coat called an elaiosome that

acts like catnip for various species of ants. About a third of our woodland wildflowers are

dispersed by ants.

Art Guppy, an Erythronium expert and close observer of ants, thinks that ants may not actually

get much out of the exchange when they disperse trout lily seed. He thinks the elaisome produces

a volatile pheromone that triggers something called the “dead corpse response.”

He observed that ants excitedly grab fresh trout lily seeds and carry them away. But, before they

get to their nests, they loose interest in the seed and drop it. Other ants pass by and pay it no

attention.

According to Guppy’s thinking, this chemical signal tricks the ant into moving the seed away from

the parent plant, but not to take it as far as the nest where conditions might be less favorable

for its germination and subsequent development.
