Unlocking fruit dimensions: Quantification of functional traits driving plant–frugivore interactions

Applications in Plant Sciences, EarlyView.
Abstract Fleshy fruits attract animals to ingest fruit, swallow the seeds, and release them in the landscape, thus facilitating seed dispersal and plant regeneration. Attraction of animal dispersers is achieved via attractants such as color or scent, and rewards like sugars, lipids, and micronutrients.

Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

The Anatomical Record, EarlyView.
We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

Produção e predação de frutos em Aniba rosaeodora Ducke var. amazonica Ducke (Lauraceae) em sistema de plantio sob floresta de terra firme na Amazônia Central Harvesting and fruit predation of a Aniba rosaeodora Ducke var. amazonica Ducke (Lauraceae) ex situ tree population in a central Amazonian upland forest

Acta Botânica Brasílica, 2004
O pau-rosa (Aniba rosaeodora) vem sendo usado desde o século passado para extração de linalol, produto usado como fixador de perfumes. Por causa do extrativismo houve redução drástica em suas populações naturais.

Sugar composition of wild fruits in Hong Kong, China [PDF]

, 1998
Soluble carbohydrates are the major nutritional reward in the pulp of most vertebrate dispersed fruits (Corlett 1996, Herrera 1987, Johnson et al. 1985, Jordano 1995). However, although detailed analyses have been made of the carbohydrate content of many

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Gut microbiomes of wild great apes fluctuate seasonally in response to diet

Nature Communications, 2018
Microbiota composition fluctuates in response to changes in environmental and lifestyle factors. Here, Hicks et al. show that the faecal microbiota of wild gorillas and chimpanzees is temporally dynamic, with shifts that correlate with seasonal rainfall ...

Padrões de interações mutualísticas entre espécies arbóreas e aves frugívoras em uma comunidade de Restinga no Parque Estadual de Itapuã, RS, Brasil Patterns of mutualistic interactions between tree species and frugivorous birds in a restinga community at Itapuã State Park, Rio Grande do Sul, Brazil

Acta Botânica Brasílica, 2007
Padrões de interação entre aves frugívoras e espécies arbóreas, com suas variações sazonais, foram determinados em uma mata de Restinga. Foram feitas observações visuais e capturas da avifauna, ao longo de um ano, estimando-se a conectância do sistema ...

Stable isotope ratios indicate that body condition in migrating passerines is influenced by winter habitat [PDF]

, 2004
Although predicted some time ago, there has been little success in demonstrating that the overall fitness of migratory birds depends on the combined influences of their experiences over all seasons.

The scaling of seed‐dispersal specialization in interaction networks across levels of organization

Ecography, EarlyView.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.
