ISB 201 1st Edition Lecture 5 Outline of Last Lecture I. Why Eat InsectsA. We already eat insectsB. Problems with meat production II. The Story of Stuff VideoA. Material economy stem crisisB. LimitationsOutline of Current Lecture III. How do we measure success of insects?IV. Symmetry in Animals V. Binomial nomenclature VI. Success of insects Current LectureIII. How do we measure success of insects?A. 5 criteria1. Ability to reproduce2. Abundance 3. Ability to live in several locations4. How long they have been around5. Ability to adapt and evolve 6. **diversity of form and functionB. Examples 1. Alligators: fulfill 1,2,4 and do not fulfill 3,5,62. Dragonflies: are very successful and check all categories C. Taxonomy field of study that involves defining organisms based on shared characteristics 1. Shared characteristics of insects: exoskeleton, 3 body parts, 6 jointed legs, l pair of antennae, wings (adult)IV. Symmetry in Animals A. A symmetrical no symmetry eg. Sponges B. Radial all parts radiating from center are identical eg. Starfish These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.C. Bilateral two identical halves eg. Insects, humans (outside not inside)V. Binomial nomenclature assigning scientific names to taxonomic groups (2 name, namegiving) A. “King Phillip Came Over For Great Sex”1. Kingdom= Animalia2. Phylum= arthropoda (joint feet)a. exoskeleton hard protective covering around the outside of the bodyb. segmented body allows movementc. jointed limbs and mouthparts allow extensive specializationd. bilateral symmetry two equal halvese. ventral nerve chord as opposed to a vertebrae nerve chord (dorsal)f. dorsal blood vessel3. Class= hexapoda (6 feet)1. Arachnids= 8 legs2. Chilopods= 1 pair of legs per body segment3. Diplopoda= 2 pair of legs per body segment4. Crustacea= 2 pair of antennae 4. Ordera. Lepidoptera= (mouths/butterflies) scale wingb. Coleopteran= (beetles) sheath wingc. Ephemeroptera= (mayflies) short lived wing; tempd. Odononta= (dragonfly/damselfly) toothede. Diptera= (flies) 2 wings5. genus 6. species a taxonomic group of organisms that are capable of breeding and producing offspring that can also reproduce in nature. Ex: two turtlesB. hybrid offspring resulting from the breeding of two different species ex: ligerC. new species created when hybrids reproduce together and ISOLATE to form their own populationVI.Success of insects D. Dominant taxonomic groupE. 80-95% of all animal speciesF. Nearly 1 million species describedG. Potentially 30 million species of insects1. Fogging trees to discover new species2. Medical use; dronesH. Insects are highly adapted to mult. Habitats1. Habitat where organisms live (address)2. Aquatic, desert, forest, alpine, tundra, islands, NOT marineI. Mult. Ecological niches1. Niche how an organism obtains energy (job)2. Plant feeding, predatory, decomposers,
