Floral neighborhood and pollination success in four hummingbird-pollinated cloud forest plant species.
In a cloud forest at Monteverde, Costa Rica, we examined pollen loads received by self-compatible flowers of two pairs of plant species pollinated by hummingbirds: Hansteinia ble- pharorachis and… Expand
THE IMPACT OF FLORAL PARASITISM IN TWO NEOTROPICAL HUMMINGBIRD‐POLLINATED PLANT SPECIES
Many angiosperm flowers produce substances (e.g., nectar, pollen, lipids) which serve as rewards for animals which are morphologically and behaviorally adapted to effect pollination by transferring… Expand
POLLINATION, FECUNDITY, AND THE DISTRIBUTION OF MOTH-FLOWERED PLANTS.
The upper altitudinal limits of moth-pollinated plants are correlated with temperatures that restrict the activity of their crepuscular pollinators. The activity of hawkmoths decreases with… Expand
Evaluation of Character Displacement Among Plants in Two Tropical Pollination Guilds
In cloud forest at Monteverde, Costa Rica, two guilds of bird-pollinated plants exist; one guild pollinated by long-billed hummingbirds, primarily the Green Hermit (Phaethornis guy), and one guild… Expand
Regeneration by fragmentation in tropical montane forest shrubs.

- 1 December 1990
both the net number of leaves and total stem length declined initially. Mortality was concentrated in a 10-month period (that included the first dry season), in which 35% of the fragments (average by… Expand
Disturbance and Predictability of Flowering Patterns in Bird-Pollinated Cloud Forest Plants.
The distribution and flowering patterns of hummingbird-pollinated plants were compared from July 1981 to June 1983 in three patch types in cloud forest at Monteverde, Costa Rica. Study plots were:… Expand
The impact of a herbivore upon Mirabilis hirsuta, a fugitive prairie plant
SummaryWe determined the effects of a host-specific moth, Heliodines nyctaginella (Lepidoptera: Heliodinidae), upon growth and seed production in Mirabilis hirsuta (Nyctaginaceae), by comparing in… Expand
Modeling the growth of individuals in plant populations: local density variation in a strand population of Xanthium strumarium (Asteraceae).
We studied the growth of individual Xanthium strumarium plants growing at four naturally occurring local densities on a beach in Maine: (1) isolated plants, (2) pairs of plants ≤1 cm apart, (3) four… Expand
