He is best known for his work on Hymenoptera, on vertebrate bones from caves, and on non-marine Mollusca especially the genus Pisidium.
The lowland leopard frog, North American river otter, beaver, muskrat, Arizona toad, and spiny-spotted turtle are among the major aquatic vertebrates found in or near the water.
The idea of a "new" vertebrate head was proposed originally by American vertebrate morphologists Carl Gans and Glenn Northcutt in 1983.
Anterior-posterior patterning by Cerberus is accomplished by acting as an antagonist to nodal, bmp, and wnt signaling molecules in the anterior region of the vertebrate embryo during gastrulation.
Superior colliculus, a paired structure that forms a major component of the vertebrate midbrain

A disc protrusion is a disease condition which can occur in some vertebrates, including humans, in which the outermost layers of the annulus fibrosus of the intervertebral discs of the spine are intact, but bulge when one or more of the discs are under pressure.

In addition, Ets factors, e.g. the vertebrate Etv1 and the invertebrate Ast-1, have been shown to be important players in the specification and differentiation of dopaminergic neurons in both C. elegans and olfactory bulbs of mice.
Based on the collections made by Philipp Franz von Siebold (who edited the text) and his successor Heinrich Bürger in Japan, Fauna Japonica’s vertebrate volumes were authored by the Leyden Museum naturalists Coenraad Jacob Temminck and Hermann Schlegel.
Teaming up with Stuart Schreiber from Harvard University, they began to study the calcium-calcineurin-NFAT pathway essential to function of the immune system and vertebrate development including neural and heart development.
He was the author of two major books on vertebrates: "Fauna der Wirbelthiere Deutschlands" (1857), and "Die wirbelthiere Europa's" (Vertebrates of Europe, with Alexander Keyserling, 1840).
He was a long-time collector from the Wealden cliffs of the Isle of Wight, and his work on vertebrate palaeontology included studies of Iguanodon and Hypsilophodon from the Wealden (Lower Cretaceous).

Jefferson's ground sloth has a special place in modern paleontology, for Thomas Jefferson's letter on Megalonyx, read before the American Philosophical Society of Philadelphia, in August 1796, marked the beginning of vertebrate paleontology in North America.
Glenn Northcutt, leader in comparative vertebrate neurobiology and evolutionary neuroscience
Omega-atracotoxin is an insect-specific neurotoxin of Blue mountains funnel-web spiders whose phylogenetic specificity derives from its ability to antagonise insect, but not vertebrate, voltage-gated calcium channels.
A professor of vertebrate paleontology and of veterinary anatomy at the University of Pennsylvania, Dodson has also taught courses in geology, history, history and sociology of science, and religious studies.
The rde-1 gene locus was first characterized in C. elegans mutants resistant to RNAi, and is a member of a highly conserved Piwi gene family that includes plant, Drosophila, and vertebrate homologs.
A Pentaceratops skeleton with a skull 3.1 meters high, the largest known of a land vertebrate.
The famous American vertebrate paleontologist Alfred Romer recognized in 1939 that the fossil amphibians described as Leptorophus levis are the larvae of Sclerocephalus.
Sonic hedgehog, an important protein during vertebrate organogenesis
Sinosaurus was described and named by Chung Chien Young, who is known as the 'Father of Chinese Vertebrate Paleontology', in 1948.
His main areas of study are late Paleozoic, Mesozoic and early Cenozoic vertebrate fossils, stratigraphy, and continental deposits, particularly in the American Southwest.
Suminia had grasping hands, which has led researchers to conclude that it was a tree-climbing animal, the earliest known such vertebrate species found thus far.
The basic form of the vertebrate foot has five toes, however some animals will have evolved fewer than this, and some early tetrapods had more; Acanthostega had eight toes.
Meszoely of the Center for Vertebrate Studies at Northeastern University in Boston, Massachusetts.
Vitreous humour, a clear gel that fills the space between the lens and the retina in vertebrate eyes
In 1983 Gehring and his collaborators (William McGinnis, Michael S. Levine, Ernst Hafen, Richard Garber, Atsushi Kuroiwa, Johannes Wirz), discovered the homeobox, a DNA segment characteristic for homeotic genes which is not only present in arthropods and their ancestors, but also in vertebrates including man.
It is not clear that lower flows in rivers adversely affect populations of aquatic species, but the Organisation for Economic Co-operation and Development (OECD) has analyzed the status of species in Chile and report that 41 of 44 vertebrate freshwater species are encountering conservation problems.
An example would be a vertebrate with an alcohol-preserved skin and viscera, a cleared and stained head, the post-cranial dried skeleton, histological, glass slides of various organs, and frozen tissue samples.
