Dominance hierarchy on palm resource partitioning among Neotropical frugivorous mammals
(2020-05-22)
In tropical forests, the diets of many frugivorous mammals overlap, yet how hyper-diverse assemblages of consumers exploit resources and coexist remains poorly understood. We evaluated competitive interactions among three ...
A question of size and fear: Competition and predation risk perception among frugivores and predators
(2020-05-22)
Mammalian spatial and temporal activity patterns can vary depending on foraging behavior or the perception of predation or competition risk among species. These behaviors may in turn be altered by human influences such as ...
Loss of mammalian species from the South American Gran Chaco: Empty savanna syndrome?
(Wiley Blackwell Publishing, Inc, 2015-01)
The Gran Chaco in central South America is a major savanna woodland ecosystem. Accelerated changes in land use within it have resulted in a complex matrix of areas with varying capabilities for sustaining wildlife. ...
Small vertebrates are key elements in the frugivory networks of a hyperdiverse tropical forest
(2020-12-01)
The local, global or functional extinction of species or populations of animals, known as defaunation, can erode important ecological services in tropical forests. Many mutualistic interactions, such as seed dispersal of ...
Combining plant-frugivore networks for describing the structure of neotropical communities
(Wiley-Blackwell, 2018-02-01)
Frugivory and seed dispersal are key processes for the maintenance of biodiversity. This is particularly true in the Neotropics, where most plant species depend on animals to disperse their seeds and most birds and mammals ...
Impact of wild boars on the feeding behavior of smaller frugivorous mammals
(2019-07-01)
We examined the interspecific relationships among wild boars, raccoon dogs, and badgers with regard to the consumption of fallen fruits to assess how the presence of the largest mammal, the boar, affects the frugivory ...
Germination response of Lithraea molleoides seeds is similar after passage through the guts of several avian and a single mammalian disperser
(Canadian Science Publishing, 2018-04-05)
Seed dispersal by vertebrate frugivores plays an important role in plant population dynamics and community structure. The gut treatment may modify the germination response of seeds; often the specific effects of seed ...
Paleoenvironments and paleoecology of the Santa Cruz Formation (early-middle Miocene) along the Río Santa Cruz, Patagonia (Argentina)
(Pergamon-Elsevier Science Ltd, 2021-08)
The continental early-middle Miocene Santa Cruz Formation (SCF) in Austral Patagonia contains the best record of South American mammalian faunas prior to the Great American Biotic Interchange (GABI) and is of particular ...
Bat frugivory in two subtropical rain forests of Northern Argentina: Testing hypotheses of fruit selection in the Neotropics
(Elsevier Gmbh, 2012-01)
Phyllostomid bats are prominent components of mammalian assemblages in the Neotropics. With many species specialized in frugivory, phyllostomids represent major partners of fleshy-fruited plants in the mutualism of seed ...
Pleistocene megafaunal extinctions and the functional loss of long-distance seed-dispersal services
(Wiley-Blackwell, 2018-01-01)
Pleistocene extinctions affected mainly large-bodied animals, determining the loss or changes in numerous ecological functions. Evidence points to a central role of many extinct megafauna herbivores as seed dispersers. An ...
