WASSMER ET AL.: SOUTH-CENTRAL FLORIDA BOBCAT ECOLOGY 219

 The data suggest the following trends in marking behavior related to the
reproductive cycle of the adult female: (1) Resident adult females with nursing
kittens tend to bury their feces in the vicinity of the den site or elsewhere in
their range but continue spray- and squat-urinating within the interior of their
ranges and along range boundaries. Young kittens probably also bury feces
near the dens. (2) Females and mobile juveniles 4-7 months old bury feces at
common, frequently-used sites near rest areas within the female's home range
and squat- and spray-urinate along travel routes. (3) At about 5-6 months of
age, juveniles begin leaving feces exposed in scrapes and probably begin to
urine-scrape as well as squat- and spray-urinate. (4) As juveniles continue to
move about the mother's range and along its boundaries, they increasingly
leave more feces exposed and make more urine and fecal scrapes. (5) About
the time juveniles are ready to disperse (which often coincides with the
breeding season of the mother), they are marking at their highest rate, as are
adults. (6) After breeding and the dispersal of their young, resident adult
females gradually decrease their rate of leaving feces exposed and increase
their rate of burying scats so that by the time new litters are born fecal marking
is minimal. (7) Intensity of adult male marking behavior parallels that of adult
females and may be at least partly a response to the marking activities of the
female and young.
 The patterns of marking behavior of Florida females and young generally
 parallel those observed by Bailey (1972, 1979) in Idaho. Ontogenetic changes
 in marking behavior of the lynx are apparently generally similar to those in
 bobcats. Lindemann (1955) reported that European lynxes began to return to
 depositories to bury urine or feces at 100-120 days of age and initiated marking
 of ranges with exposed excrement at ages of 210-220 days. Saunders (1961)
 also noted that juveniles in North America switched from burying feces to
 leaving them exposed as they grew older and thus began marking like adults.
 Few comparative data are available on seasonality of marking behavior in
 other bobcat populations, and quantitative information is limited to frequency
 of scat deposits. In northeastern Florida, Conner (1982) recorded greatest
 frequency of scats along roads, trails, and firelanes during winter and spring
 and the lowest incidence in summer and fall. In Virginia, 57% of scats
 observed along trails over a 1-year period occurred from mid-September
 through mid-March and 43% during the balance of the year (Progulske 1952).
 Frequencies of scats on Louisiana study sites were higher in winter and spring
 and lower in summer and fall (Hall 1973). Miller (1980) stated that scat
 deposition by bobcats in Alabama was more frequent in winter and early spring
 and less obvious in other parts of the year. In contrast to this and other
 southeastern studies, no seasonal pattern was evident in monthly scat
 collections made by Kight (1962) in South Carolina. Scat deposition in
 southwestern populations also showed seasonal variation. Percentages of scats
 recorded by Jones (1977) in Arizona in different months from October through
