Do frugivorous mice choose where or what to feed on?

Author(s): Fedriani, José M.
Description: Exhaustive analyses of plant–frugivore systems have revealed that few, if any, of these plant–animal interactions are tightly coevolved. Such lack of coevolutionary evidence could be related to frugivores selecting plants based on environmental cues, rather than on plant phenotypic traits. To evalua...

Dispersión de semillas por mamíferos en Doñana: beneficios del mutualismo y consecuencias para la conservación de Parque Nacional

Description: Debido a que la dispersión de semillas por animales vincula el final del ciclo reproductor de las plantas con el establecimiento de su descendencia, se le atribuyen profundos efectos sobre la sucesión, regeneración y conservación de los hábitats. En el Parque Nacional de Doñana abundan varias especi...

Predator trophic guild assignment: The importance of the method of diet quantification

Description: We quantitatively assessed the effect of three Methods of Diet Quantification (MDQ) (based on frequency of occurrence of prey, dry weight of prey remains, or estimation of fresh biomass ingested) on guild classification of three carnivores species based on five data sets. Diet dissimilarity matrices...

Functional diversity in fruit-frugivore interactions: a field experiment with Mediterranean mammals

Description: Using field seed sowings, we assessed how four mammal species (Meles meles, Vulpes vulpes, Sus scrofa, and Oryctolagus cuniculus) influenced seed germination in three fleshy-fruited Mediterranean shrubs (Corema album, Pyrus bourgaeana, and Rubus ulmifolius). We predicted that gut passage and remov...

Seed Dispersal in the Iberian Pear, Pyrus bourgaeana: A Role for Infrequent Mutualists

Description: Seed dispersal by animals is a key interaction, with effects on the population ecology and evolution of many plant lineages. Despite the fact that infrequent seed dispersers can potentially provide important services to plant populations, little attention has been paid so far to scarce mutualists. W...

Pre- and postdispersal seed predation by rodents: balance of food and safety

Description: Seed presentation and availability for seed predators change during every plant reproductive cycle. We know very little about how those changes impinge on both the ability of seed predators to impact plant populations and the foraging costs associated with seed consumption. Therefore, we conducted...

Genotyping faeces links individuals to their diet

Description: The detection of individual variation in foraging behaviour within wild mammal populations requires large sample sizes and relies on the multifold re-sampling of individuals. However, limits for observational studies are posed by the rarity and nocturnal or otherwise elusive habits...

Foraging by fearful frugivores: combined effect of fruit ripening and predation risk

Description: 1. Plant defensive compounds and predation risk are main determinants of herbivore foraging, though empirical studies have seldom measured the combined effects of these two factors. By considering the interaction between the herb Helleborus foetidus and its main fruit and seed predator, the Wood M...

Dangerous liaisons disperse the Mediterranean dwarf palm: fleshy-pulp defensive role against seed predators

Description: We chose the interaction between the Mediterranean dwarf palm (Chamaerops humilis) and its major seed disperser, the Eurasian badger (Meles meles), to evaluate the hypothesis that endozoochory is characterized by a mixture of conflicting and overlapping interests, with the capacity of bei...
