A METHOD FOR DEDUCING BRANCHING SEQUENCES IN PHYLOGENY
With the advent of relatively objective classifications, such as the phenetic classifications produced by the operational techniques of numerical taxonomy (Sokal and Sneath, 1963), it was inevitable
Nest Parasitism, Productivity, and Clutch Size in Purple Martins
TLDR
Modal brood size for parasitized and unparasitized martins was four, but there was a significant trend toward production of brood of five by mite-free birds, and of broods of three by parasitized parents, which suggests a potentially important role for nest parasitism in the determination of clutch size in martins and other birds.

Haemogregarines in snakes: the incidence and identity of the erythrocytic stages.
TLDR
Examination of zoo specimens for parasites may be expected to be quite rewarding; seldom are conditions contributing to high parasite concentrations combined with the ready availability of hosts from all over the world that a zoo offers.
NATURAL SELECTION IN MIDDLE ISLAND WATER SNAKES (NATRIX SIPEDON L.)
TLDR
The distribution of pattern types of Middle Island adults and those of the litters and the adult and litter frequencies were compared statistically using the ultraconservative test outlined by Calhoun, and the previous assumption that litter size and pattern frequency are independent was supported.
Cloacaridae, a new family of Cheyletoid mites from the cloaca of aquatic turtles (Acari: Acariformes: Eleutherengona).
A new family (Cloacaridae), a new genus ( Cloacarus ) and two new species ( C. faini and C. beeri ) of parasitic cheyletoid mites are described from the cloaca of two species of North American
Natural Selection in Water Snakes (Natrix sipedon L.) on Islands in Lake Erie
TLDR
The present study analyzes all available data on color pattern variation in the water snakes of the Lake Erie islands to illustrate a situation in which migration and strong selection pressure combine to give a relatively clear-cut picture of differential elimination of color pattern types from a population.
Climbing behavior and host-finding larval rabbit ticks (Haemaphysalis leporispalustris).
TLDR
Experiments using glass rod models to represent vegetation showed that ticks selected a position which had greatest substrate curvature and was at rabbit body height, which restricts the tick's host spectrum to rabbits and ground-dwelling or feeding birds.
