Bouquet of Genes. Watercolor and ink.
Model organisms are used to investigate specific biological problems. These particular species have traits that facilitate studies in ecology, evolution, development, physiology, biomedicine and food production. Many of the common model species in plant sciences are shown here, in an illustration inspired by the article “Field guide to plant model systems” by Chang et al. 2016, Cell.
Species from top to bottom and left to right: sunflower (Helianthus annuus), sorghum (Sorghum bicolor), rice (Oryza sativa), maize (Zea mays), moth orchid (Phalaenopsis sp.), poplar (Populus sp.), seep monkeyflower (Erythranthe guttatus), pea (Pisum sativum), wild strawberry (Fragaria vesca), tomato (Solanum lycopersicum), mouse-ear cress (Arabidopsis thaliana), spreading earthmoss (Physcomitrella patens), spike moss (Selaginella moellendorffii), grape (Vitis vinifera), Algae (Volvox carteri and Chlamydomonas reinhardtii).

The green-bearded helmetcrest (Oxypogon guerinii) and the Frailejón (Espeletia sp) have a mutualistic interaction. The hummingbird builts its nest from fiber collected from the frailejón and in return it pollinates the flowers of the frailejón.

Shakespearean Invaders of North America.
Two of the most invasive species of birds in North America, starlings and house sparrows, where introduced in the late nineteenth century to honor Shakespeare. Most of his plays mention birds, which inspired Shakespeare fans to import them. Some introductions, such as the common cuckoo, were not successful (based on “How Shakespeare Changed Everything” by Stephen Marche).
House sparrow (Passer domesticus, top), Common starling (Sturnus vulgaris, middle), and common cuckoo (Cuculus canorus, bottom).

Two of the most invasive species of birds in North America, starlings and house sparrows, where introduced in the late nineteenth century to honor Shakespeare. Most of his plays mention birds, which inspired Shakespeare fans to import them. Some introductions, such as the common cuckoo, were not successful.
This cover image was created for the special issue ‘The Presidential Symposium at the International Congress of Neuroethology 2022 in Lisbon, Portugal’ (see the editorial by Warrant 2023).
As a bird flies through its environment, the surfaces and objects appear to move across the retina, creating what is known as optic flow. Numerous studies have demonstrated that, in zebra finches (Taeniopygia guttata), two retinal recipient midbrain areas, the nucleus lentiformis mesencephali and the nucleus of the basal optic root (and their homologues in other vertebrates), contain neurons that respond to optic flow stimuli. Both of these nuclei send projections to pre-motor areas in the brainstem and cerebellum. Anatomical and physiological studies reveal how this optic flow information is integrated with other sensory signals and how cerebellar output may be driving different flight behaviors. The image is a mixed media composition by Sylvia Heredia. The background of a eucalyptus forest was drawn with watercolor. The zebra finch was painted in acrylic and based on a high-speed still image of a flying zebra finch recorded by Nicholas Tochor in a forward flight chamber at the University of British Columbia. The see-through brain, bones and muscles were rendered in Adobe Illustrator. Courtesy and copyright of the cover image: Sylvia Heredia, University of British Columbia. Text by Douglas L. Altshuler
