Use of native and exotic garden plants by suburban nectarivorous
The flowers are very popular among animals--ranging from nectarivorous
bats, perching birds and hummingbirds to wasps, bees and hawkmoths--making the sexual reproduction usually very successful.
Bats from a variety of species, including insectivorous, nectarivorous
, frugivorous, and hematophagous bats, were included in this study for the purpose of obtaining a diverse array of potential exposures.
The 2 experimental values of the body surface area-related GFRs (Table 5) were compared with published values for birds, (17-20) Bennett and Hughes (19) divided data according to the diet of birds as herbivorous, nectarivorous
, carnivorous, and omnivorous (Fig 2).
Kunz and his colleagues describe dietary preferences, foraging behaviors, adaptations and phylogenetic histories of insectivorous, frugivorous and nectarivorous
bats worldwide in the context of their respective ecosystem services.
Students manipulate the nutritive gain available from flowers to test the hypothesis that the foraging behavior of nectarivorous
insects maximizes energy gain rate.
Choeronycteris mexicana), they represent the primary nectarivorous
Effects of forest fragmentation on frugivorous and nectarivorous
bats in French Guiana.
Nectar's value as a dietary source of energy has been well established for nectarivorous
insects, such as bees and butterflies; and predaceous arthropods other than spiders have been shown to survive periods of prey deprivation by feeding on plant nectars (Yokoyama 1978; Hagen 1987; van Rijn & Tanigoshi 1999; Limburg & Rosenheim 2001).
Donald Franklin and Dr Richard Noske from the CRC for the Sustainable Development of Tropical Savannas, and the Northern Territory University, looked at the bill length and body weight of certain nectarivorous
birds (including lorikeets and honeyeaters), and the flower structure of plant species on which the birds fed, to see if bird and flower morphology (structure) were linked.
Although studies from temperate upland forests have shown that urbanization tends to select for omnivorous, granivorous, and cavity nesting bird species (Chace and Walsh 2006), studies from tropical and subtropical areas have recorded a noteworthy predominance of frugivorous, insectivorous, and nectarivorous
species in urban areas (Ortega-Alvarez and MacGregor-Fors 2011).
