We describe the agonistic interaction between the opossum and a bat of the species Artibeus lituratus while they foraged on the same infructescences
of Cecropia glaziovii and C.
were found on dry stems and leaves surrounding infructescences
collected at Ziemupe, Dr E.
Plants growing in CE produced more quaternary shoots than plants in the other two vegetation types (Table 1), and an increased production of quaternary shoot led to higher infructescence
production (Table 2).
In 2006 and 2007, we calculated seed production per plant by weighing all the seeds per infructescence
and multiplying the number of seeds per infructescence
by the average number of infructescences
produced per plant over a 14-year monitoring period across Nebraska sites (Stubbendieck et.
Subacaulescent or with a short stem up to 4 m in height, 22 cm in diameter; leaves up to 7 m long; infructescence
erect to arching horizontally; fruit obovoid, symmetrical--Astrocaryum giganteum
Since the seeds of Pilea pumila are extremely small and their maturation is relatively synchronous, the number of nodes with infructescences
of each individual were counted and then harvested 120 d after planting (8 October 1995) and infructescence
mass was determined.
These measurements were relatively easily done, given the large size of the seeds (3 cm in diameter) and the low and constant number of seeds per infructescence

has the radial symmetry and large fruits typical of Werauhia species (Figure 4).
The number of fruit in each infructescence
was recorded and each leaf subtending the elongating shoot bearing the focal infructescence
was scored for the presence of anthracnose lesions.
We excluded the Araceae (anthuriums) from variables 1 and 2 because it was difficult to estimate fruit numbers for each infructescence
For inflorescences receiving outcrossed pollinations, we did not detect a significant effect of damage on infructescence
