Other Vocabulary:

  • Apothecia: [a-poth-EH-cee-ah] concave cup formations on lichen that bear the spores; asocarp
  • Bilateral Gynandromorph: an organism that contains both male and female characteristics that can be distinguished through sexual dimorphism. Usually seen in moths, butterflies, other insects and birds.
  • Cilia: outgrowths on the thallus of lichen that look like eyelashes or tentacles
  • Crown Shyness: gaps in the canopy between trees in the forest that allow for sunlight to get through, and help the trees “social distance” to help neighboring trees to avoid infections and infestations.
  • Fasciation: also known as cresting, a relatively rare condition of abnormal growth in vascular plants in which the growing tip which normally is concentrated around a single point and produces approximately cylindrical tissue, instead becomes elongated perpendicularly to the direction of growth, thus producing flattened, ribbon-like, crested (or “cristate”), or elaborately contorted, tissue.
  • Inquiline: an animal exploiting the living space of another, e.g. an insect that lays its eggs in a gall produced by another (not the same as parasite because they don’t necessarily adversely affect the host.)
  • Intergrade: There are two types of intergradation: Primary intergradation: Occurs in cases were two subspecies are connected via one or more intermediate populations, each of which are in turn intermediate to their adjacent populations and exhibit more or less the same amount of variability as any other population within the species. Adjacent populations and subspecies are subject to cline intergradation, and in these situations it is usually taken for granted that the clines are causally related to environmental gradients. Secondary intergradation: When contact between a geographically isolated subspecies is reestablished with the main body of the species or with another isolate subspecies, interbreeding takes place as long as the isolate has not yet evolved an effective set of isolating mechanisms. Consequently, a relatively distinct zone or belt of hybridization will develop depending on the degree of genetic and phenotypic difference that was achieved by the previously isolated subspecies.
  • Isidia: [EYE-sid-ee-ah] ; small outgrowths of the thallus, from about 50 micrometres to a millimetre or so in length. They contain both fungal hyphae and photobiont cells and vary in shape, depending on species, from bulbous to cylindrical or branched, sometimes even coralloid .
  • Osmeteria: the “horns” on the head of swallowtail caterpillars. “…The everted organ resembles a fleshy forked tongue (not unlike a snake tongue)… [and emits] a foul, disagreeable odor which serves to repel ants, small spiders, and mantids…”
  • Soredia: [SORE-dee-ah] powdery grainy-looking balls composed of fungal hyphae wrapped around cyanobacteria or green algae on lichen; asexual reproduction
  • Teneral: of, relating to, or constituting a state of the imago of an insect immediately after molting during which it is soft and immature in coloring.
  • Thanatosis: “death drop” insect use to evade capture. Feigning death is a technique used by lots of different critters, including the opossum.
  • Thigmotropism: the turning or bending of a plant or other organism in response to a touch stimulus (what causes a vine to wrap around a tree, for example)
