Frugivore - Wikipedia, the free encyclopedia A frugivore is an animal that feeds primarily or less commonly exclusively on fruit. As the reproductive means for the plant, the plant species may have may have evolved means to either prevent animals from consuming their fruits, or conversely the fruit may have evolved to be entice frugivores to the plant. Just as plants who work with their attendant frugivores may affect change on the consumer and themselves over time, the deterrent plants can also get into an evolutionary arms race with animals. en.wikipedia.org /wiki/Frugivore   (964 words)

VARIATION IN RESOURCE ABUNDANCE AFFECTS CAPTURE RATES OF BIRDS IN THREE LOWLAND HABITATS IN COSTA RICA   (Site not responding.

Fruit and frugivore abundance.--We examined temporal changes in abundance (capture rates) of frugivores to determine if such changes were influenced by spatial and temporal variation in fruit abundance or simply a reflection of move- ments of individuals unrelated to fruit abun- dance. The lack of positive correlations in seasonal capture rates among trophic groups and the correlation between frugivores and fruit abundance support the view that temporal and spatial variation in bird abundance in tropical bird communities is at least partially in response to variation in resource abundance. elibrary.unm.edu /sora/Auk/v108n01/p0114-p0130.html   (12041 words)

Frugivore Birds, Mammals, and Fish Peccaries, tapir, and toucans are all fruit-eaters, or frugivores, and are part of an astounding range of frugivores that feed on seasonally scarce fruit resources. Weare measuring the seasonal patterns of fruiting plants and identifying the diet of the region's main frugivores. We are studying which species of fruiting plants are key to frugivore survival, revealing the complex interactions that sustain the forest ecosystem. www.earthwatch.org /expeditions/pantanal/fruit-eaters.html   (355 words)

Gut Morphology--Conclusion / Clarifying 'Omnivore' vs 'Faunivore' Note that the frugivore classification above came from using the coefficient of gut differentiation, which is an intermediate result in Chivers and Hladik [1980, 1984], hence presumably less desirable (from a certain analytical viewpoint) than the (faunivore) classification achieved using the end result of Chivers and Hladik [1980, 1984], i.e., the index of gut specialization. Also recall that the term frugivore does not mean or imply that a diet of nearly 100% sweet fruit (as advocated by some fruitarians) is appropriate. Thus the result that humans appeared to be frugivores by one measure and faunivores by another suggests a natural diet for humans that includes both animal foods and fruits. www.beyondveg.com /billings-t/comp-anat/comp-anat-6e.shtml   (3973 words)

Patterns of movement and seed dispersal of a tropical frugivore.   (Site not responding. Last check: 2007-10-22) Patterns of movement and seed dispersal of a tropical frugivore. Because tropical avian frugivores disperse seeds of many plant species, the temporal and spatial patterning of their movement will influence seed distribution within a habitat. Here we consider the movement of an understorey frugivore, the flycatcher Mionectes oleagineus, which is a resident of the understorey in lowland wet tropical forests of the Neotropics. trophort.com /information/data/B01/S39/WES00PAT2491834.html   (297 words)

Human diet (Steve Harris, M.D.) Instead, it appears to be an adaptation from a former frugivore which has undergone quite a bit of additional natural selection. Show me a human with very dark skin with all his excess nutritional calorie storage fat on his butt, where it can sit without giving him heatstroke, and I'll show you somebody adapted for a tropically sunny, hot climate where eating fruit all year around might be possible. I said and implied that it was meat eaters >and frugivores I referred to, rather than grass eaters, because I have >less knowledge about perspiration in grass eaters than I do about meat >eaters and fruit eaters. yarchive.net /med/human_diet.html   (6661 words)

Scientific activities and projects - Pedro Jordano   (Site not responding. Last check: 2007-10-22) One of the two subprojects focuses on plant-animal interactions, supplementing this theoretical approach with an empirical study of landscape patterns of gene flow and the demographic effects of frugivore activity on plant populations. i) the spatial genetic structure of reproductive adults; ii) patterns of habitat use by frugivores; iii) resulting patterns of seed dissemination; and iv) the spatial patterns of seed genotypes and their distance and spatial relation to maternal trees and major landscape features. We consider three groups of evidence to assess evolutionary response to selection by frugivores: effects on fitness variation in wild populations, genetic and demographic effects derived from animal-mediated seed dispersal, and evolutionary (phylogenetic) correlations between plant and frugivore traits. ebd10.ebd.csic.es /mywork/sciactiv.html   (1986 words)

Frugivore   (Site not responding. Last check: 2007-10-22) A frugivore is an animal that feeds on fruit. Thus, many birds eat both fruits, such as wild berries, and insects (examples include the American Robin or the Cedar Waxwing) or seeds (e.

Ecology: Frugivore-mediated selection on fruit and seed size: birds and St. Lucie's cherry, Prunus mahaleb Despite relatively high fruit removal by frugivores in the two study years ([greater than]75% of the initial fruit crop), the activity of legitimate seed dispersers limited successful seed dispersal, as only half of the ripe fruit crop was consumed by this type of frugivore. Variance in seed dispersal efficiency is high, but subject to ample between-year variation due to changes in composition of the frugivore assemblage (Jordano 1994), leading to a minor contribution of individual plant effects ([less than]15%) to explain either fruit removal or seed dispersal efficiency (see also Willson and Whelan 1993). Frequently, frugivores might exert at best weak, statistically insignificant, selection on maternal fruit size and seed mass in wild populations, where plant fecundity differences usually obscure the influences of mutualists in 'rate processes' that marginally contribute to fitness differences (see, e.g., Herrera 1988, 1991, 1993, Jordano 1989, Campbell 1991, Johnston 1991, Mitchell 1994). www.findarticles.com /p/articles/mi_m2120/is_n8_v76/ai_17848349/pg_5   (1200 words)

Auk, The: Importance of seed ingestion to an avian frugivore: An experimental approach to fruit choice based on seed ... However, there are three major costs of fruit consumption to avian frugivores, each of which relates to the ballast load in the gut created by consumption of indigestible seeds (Levey and Grajal 1991, Witmer 1998). Frugivorous birds can potentially reduce the cost of processing seeds by discarding them, selecting fruit that have a low seed load, or choosing fruit in which seeds are packaged in a way that allows the frugivore's gut to process them more rapidly. However, the majority of avian frugivores in Howe and Vande Kerckhove's (1981) study regurgitated seeds fairly rapidly, which would reduce the cost of the ballast load to the birds anyway. www.findarticles.com /p/articles/mi_qa3793/is_200201/ai_n9070452   (1438 words)

EPA: ORD: NCER: Fellowships This study investigates the relative significance of dispersers on the initial phase of forest organization, the seed rain. Most tropical plants produce fleshy fruits, and vertebrate frugivores act as their primary dispersal vectors. I am currently examining: 1) to what degree fruiting trees act as dispersal foci in closed canopy forests, 2) differential seed shadows generated by avian and primate frugivores for six focal tree species, 3) if seed rain patterns produced by the frugivore community result in predictable associations among tree species in the adult forest structure. es.epa.gov /ncer/fellow/progress/99/clarkco00.html   (397 words)

Anthropogenic edges, treefall gaps, and fruit-frugivore interactions in a neotropical montane forest.   (Site not responding. Last check: 2007-10-22) Fruit-sampling plots (50 msuperscript 2 plots) at each of the 4 distances were classified into gap and intact forest. Fruit abundance and frugivore capture rates varied from edge to forest interior, but such changes depended on edge age. At new edges, the total number of fruits was higher at the forest edge than at the forest interior, whereas bird captures showed the opposite trend. trophort.com /information/data/B01/S48/RES99ANT6682666.html   (236 words)

Positive Health Magazine   (Site not responding. Last check: 2007-10-22) Man, a frugivorous species (living on fruit, nuts and succulent vegetables), became a flesh eater when his original habitat was destroyed during the Ice Ages. But very few people realize that for a frugivore to eat like an omnivore or a carnivore is as big a departure from the natural order as for a herbivore to eat like a carnivore. Naturalists and comparative anatomists, such as Linnaeus, Cuvier, Haeckel and TH Huxley, have long agreed that Man should be classed as a frugivore. www.positivehealth.com /test/articles.asp?i=1004   (885 words)

ESA 2004   (Site not responding. Last check: 2007-10-22) To understand the variation in plant-frugivore mutualism, we examined Vaccinium membranaceum and its frugivores in a mosaic of primary and secondary succession at Mount St. Helens. We conducted experiments to investigate the species interactions affecting fruit crop size, and to test whether frugivores choose to forage at a particular plant on the basis of the total amount of energy available (fruit crop size hypothesis). We found that differences in plant interactions with pollinators and herbivores resulted in a 51.5% reduction in fruit set in primary compared to secondary succession. abstracts.co.allenpress.com /pweb/esa2004/document?ID=37723   (187 words)

FOOD CACHING IN THE TROPICAL FRUGIVORE, MACGREGOR'S BOWERBIRD (AMBLYORNIS MACGREGORIAE) Observations of marked males in 1980 indicated that they spent an av- erage of 54% (range = 20-75%) of daylight hours within a 20-m radius of the bower, and this core area was aggressively defended. macgregoriae was primarily frugivorous; 95% of its diet consisted of medium to large drupes and, to a lesser degree, arillate fruits. In this paper we describe food-storing be- havior in MacGregor's Bowerbird (Amblyornis macgregoriae), a frugivorous species found in montane rain forest in New Guinea. elibrary.unm.edu /sora/Auk/v102n02/p0334-p0341.html   (8192 words)
