“…Both within and among species, we found a positive correlation between crop size and removal rate (fruit per day). In this respect, our data are consistent with most (Howe and DeSteven 1979;Howe and Vande Kerckhove 1979;Murray 1987;Gryj and Dominguez 1996), but not all (Bronstein and Hoffman 1987) studies.…”

“…Furthermore, we use these data to assess the effect of various factors on fruit removal. For example, some authors (Howe and DeSteven 1979;Howe and Vande Kerckhove 1979;Murray 1987;Gryj and Dominguez 1996; but see Fleming 1981), report that there is a positive relationship between crop size and number of individual frugivores attracted, resulting in increased fruit removal. Finally, using published information on the dietary requirements of bats, we estimate the number that feed on the ripe fruits of a fig tree and disperse its seeds to assess the relative importance of figs as a keystone resource.…”

“…The "rates-versus-numbers" problem illustrated in this paper is not unique to the study of the maternal component of reproduction, but presumably applies also to some other fields in plant reproductive ecology where rate-based, relative measures have been frequently used (e.g., seed dispersal, seed predation; De Steven 1981, Murray 1987, Herrera 1 9 8 8~) .…”

“…Plants producing large numbers of flowers often receive fewer pollinator visits, and have a lower fruit set, on a per flower basis than conspecifics producing fewer flowers, yet individuals with the largest floral displays are still those producing most seeds (Wyatt 1980, Andersson 1988, Klinkhamer et al 1989. Similarly, in some bird-dispersed plants the proportion of seeds that is dispersed depends on traits like fruit size, crop size, and fruit seediness, yet absolute numbers are often unrelated to individual variation in these traits (Murray 1987, Herrera 1988a, Obeso 1989.…”

“…5B). Several studies show that bird visitation and fruit removal are positively correlated with fruit crop size, both at the habitat level and the individual plant level (Murray 1987;Sargent 1990; but see Davidar and Morton 1986). Del Rio et al (1996) found that avian seed dispersal of mistletoes was strongly dependent on the prevalence of mistletoe on individual plants.…”
