Reproduction in plants often requires animal vectors. Fruit and flower colors are traditionally viewed as an adaptation to facilitate detection for pollinators and seed dispersers. This longstanding hypothesis predicts that fruits are easier to detect against their own leaves compared with those of different species. We tested this hypothesis by analyzing… (More)
Fundamental concepts about the diversity and evolution of signals have been developed mainly in the context of sexual selection. Here, we review the functional ecology of signals in a different context, that of plant–animal interactions. The visual signals of fruits and flowers are relatively constant and clear in the message that they convey. Thus, plant… (More)
Although many studies have been published on avian fruit selection, few have addressed the effects of fruit scarcity on the patterns of fruit choice. Here, we compared the consumption of seven bird species for six simultaneously present maturation stages of Goupia glabra fruits. Ripe G. glabra fruits contain more lipids, carbohydrates and energy, and fewer… (More)
In a survey of particulate fallout in homes it was found that there is a relation between pollution inside and outside a home. The level inside the home also depends on the location of the home (urban, suburban, or rural). Bathrooms and kitchens show heavier particle fallout than living rooms or bedrooms.
When relatively clean country air is exposed to the saturated vapor of iodine or turpentine, very large numbers of condensation nuclei develop. It is believed that such air contains clusters of molecules that are polymerized by the vapor of turpentine or iodine to form nuclei.
