We live in the chihuahuan desert
Classification of a species is organized by:
Taxonomy is the practice and science of classification of living things.
THe desert food chain starts with nitrogen fixation
Nitrogen fixing plants: take nitrogen from the atmosphere and store it in nodules in the roots
c3, c4, cam plants
plants communicate through a fungal network
Mycorrhizae: a fungus that grows in association with the roots of a plant in a symbiotic or mildly pathogenic relationship
Mycorrhiza: is a symbiotic association between a fungus and the roots of a vascular host plant, although 29% are non-mycorrhizal plant species.
The term mycorrhiza refers to the role of the fungi in the plants' rhizosphere, its root system.
A phylogenetic tree or evolutionary tree is a branching diagram or "tree" showing the evolutionary relationships among various biological species or other entities—their
Phylogeny—based upon similarities and differences in their physical or genetic characteristics.
Bacteria- a type of biological cell. They constitute a large domain of prokaryotic microorganisms. Shapes, ranging from spheres to rods and spirals.
Archaea- a domain of single-celled microorganisms, prokaryotes, meaning they have no cell nucleus, found inside plankton and in extreme environments like volcanic sites
Eukarya- includes eukaryotic organisms. These are organisms with cells that contain a nucleus as well as membrane-bound organelles.
Etymology. The word arthropod comes from the Greek ἄρθρον árthron, "joint", and πούς pous (gen. podos), i.e. "foot" or "leg", which together mean "jointed leg".
Orthoptera: ortho- straight, ptera-wing, grasshoppers, locusts and crickets
Hymenoptera: is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones.
Etymology: Hymenoptera comes from the Greek words Greek words hymen meaning membrane and ptera, which means wings. This refers to their filmy, or membranous, wings.
Lepidoptera: Members of this order include: butterflies and moths. Etymology: Lepidoptera comes from the Greek words lepido, which means scale, and ptera, which means wings.
Coleoptera: Beetles Etymology: Coleoptera comes from the Greek words koleos, which means sheath, and ptera, which means wings. This refers to the hardened forewings, which are known as elytra in beetles.
Roly Polies, pill bugs
Desert shrimp: eggs can stay dormant for 30 years
Found in ditches, ponds, pools and other ephemeral freshwater habitats in northern Mexico and parts of the southern and southwestern United States, west of the Mississippi River.
9:40 sun spider, 11:30 giant desert hairy scorpion, 14:00 long nosed snake, 17:30 spadefoot toad, 18:30 rattlesnake
hawk wasp: State insect of New Mexico
Parasitic Hawk Wasp will paralyze tarantula and lay an egg in them then drag the tarantula to a burrow where the egg(s), usually a single egg, hatch and eat the semi paralyzed tarantula

Opuntia: commonly called prickly pear, is a genus in the cactus family, Cactaceae. Prickly pears are also known as tuna, sabra, nopal from the Nahuatl word nōpalli for the pads, or nostle, from the Nahuatl word nōchtli for the fruit; or paddle cactus.
Nahuatl: a member of a group of peoples native to southern Mexico and Central America, including the Aztecs. Current native speakers: over 1.7 million
Varieties: divided by type of spines, flower colors, size of pads
web site on Opuntia varieties: http://eol.org/pages/37701/overview
Noticeable traits: -flat paddle-shaped stem segments called cladodes
-tiny, easily detached spines called glochids that
look soft and fuzzy but spine you up
-formidable spines in addition to the glochids
-flowers are typically yellow, sometimes pink, and rarely white
Uses: can be eaten, some animals can chew up the spines,
you can roast them, peel, or eat the red fruit
Who is in there? road runners nest in there
Ecology: Does not like soggy soil, naturally grows throughout North and South America from as far north as Canada, through the Caribbean, and down into Argentina.
Our desert used to be more of grassland than a shrubland but cows changed that
Entire plant is edible including the tasty black seeds. Nutrients: protein, vitamins C and B6, riboflavin, thiamin, folate, pantothenic acid, magnesium, phosphorous, potassium, iron, and calcium.
Red varieties are used by Hopi communities as red dye.
Desert cacti can be eaten in an emergency, but it is nice to let it live and thrive
