The ISES logo aims at encompassing the major fields of study in serpentine ecology and depicting how those fields are related to each other.  The basic shape of the logo, a circle, suggests the global nature of serpentine ecology.  Four points on the perimeter of the circle represent the four cardinal directions, north, south, east, and west, further emphasizing the global or international nature of our organization.  Within the logo, representative subjects of the major fields of study in serpentine ecology are represented including, geology, soils, plants, animals, microorganisms, sea floor, astrobiology, and human interactions.  Geology is represented in layered tones of green and brown and depicts an ophiolite sequence emerging from the sea floor.  Soils are represented by two soil horizons ontop of the ophiolite sequence. The soils with its typical red color consist of a saprolythe layer (bottom) and a limonite layer (on top). Plants are represented by Alyssum bertolonii, the first identified serpentine endemic and nickel hyperaccumulator of Italy.  Animals are represented by Melanotrichus boydii, an insect species endemic to serpentine in California, USA by virtue that its host plant, Streptanthus polygaloides is also a serpentine endemic.  Microorganisms are represented by a ectomycorrhizal fruiting body (mushroom) Cortinus magellanicuswhich is generally restricted to serpentine soils in New Caledonia.  The white tower on the ocean floor represents The Lost City of the Atlantic ocean floor.  The Lost City is composed of calcium carbonate towers produced by serpentinization of oceanic crust.  The meteor represents astrobiology and hints that serpentine ecosystems may represent model habitat for life on other planets and the accumulating evidence that life on earth itself started in serpentine ecosystems.  The letters I-S-E-S occupy the center of the logo with the "I" represented as a stylized human figure to symbolize human interactions with serpentine ecosystems.  The raised arms of the human, combined with the arc of the circle and the head of the human in the center creates an eye, denoting observation or study of these fascinating ecosystems worldwide.
