Sayo-Art Prints and Gifts

Walking Octopus

Scientists recently observed the coconut octopus walking along the sea floor. Researchers are unsure why, but suspect it might be a stealthier way to move unnoticed. Digitally rendered for the National Science Foundation.

Vole Animal Behavior

Prairie Voles males are devoted fathers, compared to the similar Montane voles who have no loyalty to their mates or family. Researchers found that random changes altering the length of microsatellite DNA near the gene for the vasopressin receptor affect social behavior in male voles. A longer microsatellite region resulted in more bonding and care giving. Digitally rendered for the National Science Foundation.

Dinosaur Extinction

An unfortunate dinosaur watches the impending asteroid impact. Drawn for the cover of Earth magazine about the many extinction events throughout Earth's history.

Majungatholus Dinosaur

The Majungatholus atopus dinosaur was related to T. rex. Teeth marks on some bones indicate that they were likely cannibals. Digitally drawn for the National Science Foundation.

Redwood Flower Beetles

This watercolor painting shows Fauna and Flora of the Redwood Forest Floor: Longhorn Flower beetles enjoy the sorrel and violets growing among the litter of redwood trees.

Frog Fungus and Warming Earth

Recent studies show the warming climate is contributing to the increase of chytrid disease, a fungus infection that is responsible for the extinction of many tropical frog species. The fungus, Batrachochytrium dendrobatidis, infects tadpoles and eventually attacks the skin of adults and kills them. Scientists know the spore stage can swim through water to infect other frogs, but there is still much to know about how the disease spreads, and if it can survive in other animals. This illustration was drawn for the National Science Foundation.

Carnivore Skulls of the American West

Carnivore Skulls of the American West: Skulls of cougar (Felis concolor), grey wolf (Canis lupus), grizzly bear (Ursus arctos horribilis)). Painted with acrylics.

Plant Immune Response

Bee social roles change as they age. This digital drawing was created for the National Science Foundation for their web site on FIBR grants, encouraging cross-discipline research. This particular research combines genomics, behavioral research, mathematics and computer science.

Singing Fish

Some fish sing to attract mates. Digitally rendered for the National Science Foundation.

Swallowtail and Blue Azure Butterfly

Comparison of two butterflies (not to scale), of a swallowtail and a blue azure butterfly. Swallowtail painted in watercolor and the blue azure butterfly drawn in color pencil. Personal art.

Dragonfly

This acrylic painting of a dragonfly was created for the National Science Foundation for a special report highlighting science using sensor technology to follow the movement of different animals. Scientists have created tracking devices small enough and light enough to sit on a flying dragonflies back.

Ugly African Animals

Unaesthetically unappreciated Animals of Africa drawn with color pencils. Including the vulture, wild dog, marabou stork, ostrich, warthog and hyena.

Arctic Iceberg Oasis

Counter to what one might expect, large icebergs in the Arctic ocean are beacons for life. Digitally rendered for the National Science Foundation.

Elk

Painted in acrylic for the National Science Foundation.

Singing Green-Eyed Tree-Frog

Green-eyed frogs in Australia recognize potential mates by the pitch and note rate of males songs. Geographic isolation has allowed the songs of different subpopulations to change to the point that they no longer recognize one another, even though their offspring are viable. Color pencil and digital rendering for the National Science Foundation.

Plesiosaur Mother and Baby

Scientists in Antarctica found the fossil remains of a baby plesiosaur, killed and preserved by a volcanic eruption. The fossils date to the late cretaceous age (70 million years ago), when ancient reptiles like this roamed the seas. Painted in Acrylic and digitally composed for the National Science Foundation.

Diving Penguin

Penguins may look awkward on land, but they´re adaptations allow them to dive to far greater depths than humans (even with scuba gear). Digitally rendered for the National Science Foundation.

Ocelot Hunting the Agouti

In Panama scientists are studying the intricate relationship between prey and predator. Painted in Acrylic for the National Science Foundation.

Hydrothermal Sea Vent Communities

Strange creatures live off the energy from sea vents, deep beneath the ocean. Digitally rendered for the National Science Foundation.
