Of the following sets of species, state which species definition (morphological, phylogenetic, or biological) best applies
a. Species boundaries in many tiny organisms, such as Oligotrich ciliates that live in the ocean, are determined using features that are visible under a light microscope.
b. Two wild relatives of lettuce, Lactuca canadensis and Lactuca graminifolia, produce flowers at different times â L. canadensisflowers in summer and L. graminifolia flowers in early spring.
c. As their names suggest, spring field crickets (Gryllus veletis) mature and become reproductively active in the spring, while fall field crickets (Gryllus pennsylvanicus) mature and reproduce in the fall.
d. Several closely-related (and very similar-looking) species of fungus in the genus Wallemia were identified using an evolutionary tree based on DNA sequences from several genes.
e. The breeding season for the red-legged frog (Rana aurora) occurs between January and March, while the breeding season of its close relative (Rana boylii) lasts from March through May.
f. Analysis of evolutionary relationships among several species of crayfish in the genus Pacifastacus were used to distinguish species from one another, and to identify species of possible conservation concern.
