exam 3 (ch 8-12)

what are some predictors/parameters for breeding in reptiles and amphibians (including seasonal, continuous examples)?

amphibians

• rainfall is strong stimulus for breeding in temperate and tropical climate zones

• most in temperate zone are highly seasonal in timing of breeding, most breed in late winter/early spring when rainfall is more predictable (some in mid-summer and others in fall)

• tropical species mostly breed in rainy season, but some species in tropical areas without great changes in temperature or rainfall throughout seasons breed year-round

reptiles

• events leading up to mating include maturation of gonads, development of secondary sexual structures, courtship

explain internal vs. external fertilization in herps

what are common modes of reproduction for different groups of amphibians and reptiles?

define the unique role of reproductive features in herps (e.g. spermatophore, hemipenis, etc.)

what are the different types of eggs?

define sex determination and the different types of temperature dependent sex determination

give some examples of asexual reproduction

how do herps maintain a center of gravity?

what are the different types of levers in herp movement?

what are the various forms of movement for a reptile (e.g. burrowing, terrestrial surface, arboreal, etc…)?

explain wet vs. dry adhesion

what are the different types of locomotion in herps?
