Article
Full-text available
Seed dispersal by vertebrates is one of the most common and important plant-animal mutualisms, involving an enormous diversity of fruiting plants and frugivorous animals. Even though plant reproduction depends largely on seed dispersal, evolutionary ecologists have been unable to link co-occurring traits in fruits with differences in behavior, phys...
Article
Full-text available
The Dispersal Syndrome hypothesis remains contentious, stating that apparently nonrandom associations of fruit characteristics result from selection by seed dispersers. We examine a key assumption under this hypothesis, i.e. that fruit traits can be used as reliable signals by frugivores. We first test this assumption by looking at whether fruit co...
Article
Full-text available
Recent studies of plant-animal mutualistic networks have assumed that interaction frequency between mutualists predicts species impacts (population-level effects), and that field estimates of interaction strength (per-interaction effects) are unnecessary. Although existing evidence supports this assumption for the effect of animals on plants, no st...
Article
According to diet‐regulation hypotheses, animals select food to regulate the intake of macronutrients or maximise energy feeding efficiency. Specifically, the nutrient balance model proposes that foraging is primarily a process of balancing multiple nutrients to achieve a nutritional intake target, while the energy maximisation model proposes that...
Article
Switching plant species visited by pollinators (partner flexibility), has been proposed as a behavioural mechanism able to attenuate the negative impacts of shifts in plant communities on pollination. However, it is unclear if the magnitude of such response is generalizable or depends on the environmental context. Moreover, the ability of pollinato...
Preprint
As the scientific environment is hierarchical and meritocratic, greater dedication will lead to higher performance. Consequently, scientists with caregiving responsibilities will suffer downfalls in performance. Caregivers are mainly women so their career is more affected than their male counterparts’. Based on a self-perception survey among Argent...
Article
Full-text available
Morphology and phenology influence plant–pollinator network structure, but whether they generate more stable pairwise interactions with higher pollination success remains unknown. Here we evaluate the importance of morphological trait matching, phenological overlap and specialisation for the spatio‐temporal stability (measured as variability) of pl...
Article
Full-text available
Plant performance is based on the relationship between resource acquisition and allocation to complete essential functions. Herbivory causes compromises in resource allocation that impact at the plant and within-plant (sub-individual) levels. This impacts fruit display traits which in turn affect reproductive success and seed dispersal. Because lea...
Article
Full-text available
Dioecy allows separation of female and male functions and therefore facilitates separate co-evolutionary pathways with pollinators and seed dispersers. In monoecious figs, pollinators’ offspring develop inside the syconium by consuming some of the seeds. Flower-stage syconia must attract pollinators, then ripen and attract seed dispersers. In dioec...
Article
Full-text available
Water availability may affect plant productivity because it limits a plant’s ability to reproduce and defend itself. In this field study, we studied the effect of water increment in relation to: a) flower production, b) fruit production and c) herbivory, focusing on Fuchsia boliviana (Onagraceae) in the Yungas forest of Northwestern Argentina. We s...

Article
Full-text available
Mutualistic interactions are at the core of community dynamics, determining dispersal, colonization, and differential survival and reproduction among individuals and species. Mutualistic interactions therefore affect the fitness of interaction partners, hence modifying their respective evolutionary trajectories reciprocally, potentially leading to...
Article
Full-text available
Tolerance to extreme temperatures, thermal limits, and the mechanisms of thermoregulation are related to internal functions of insects and partly define their ecological niche. We study the association between daily activity of dung beetles from the Monte Desert in Argentina and their tolerance to high temperatures. Results indicate that for all th...
Article
Full-text available
In visually-driven seed dispersal mutualisms, natural selection should promote plant strategies that maximize fruit visibility to dispersers. Plants might increase seed dispersal profitability by increasing conspicuousness of fruit display, understood as a plant strategy to maximize fruit detectability by seed dispersers. The role of different pla...
Article
Full-text available
The ability of a plant’s propagule to reach microhabitats with the adequate conditions for seed germination and sapling establishment will have a direct effect on the plant’s fitness. In the case of fleshyfruited plants, the seeds are dispersed by frugivorous animals. One part of the seed dispersal process is the removal of the fruits, which contai...
Article
La habilidad del propágulo de una planta para alcanzar un sitio con las condiciones adecuadas para la germinación de la semilla y el establecimiento del renoval tendrá un efecto directo en la aptitud (“fitness”) de la planta. En el caso de plantas con frutos carnosos, las semillas son dispersadas por animales frugívoros. Una parte del proceso de di...
Article
Full-text available
Previous studies have examined separately how pollinator generalization and abundance influence plant reproductive success, but none so far has evaluated simultaneously the relative importance of these pollinator attributes. Here we evaluated the extent to which pollinator generalization and abundance influence plant reproductive success per visit...
Article
Full-text available
How many dimensions (trait-axes) are required to predict whether two species interact? This unanswered question originated with the idea of ecological niches, and yet bears relevance today for understanding what determines network structure. Here, we analyse a set of 200 ecological networks, including food webs, antagonistic and mutualistic network...
Article
1. The study of plant-pollinator interactions in a network context is receiving increasing attention. This approach has helped to identify several emerging network patterns such as nestedness and modularity. However, most studies are based only on qualitative information, and some ecosystems, such as deserts and tropical forests, are underrepresent...
Article
Full-text available
We studied the consequences of nest-site choice on nesting success under differing disturbance levels for the Rufous-bellied Thrush (Turdus rufiventris). We compared nest-site choice and nest success between a disturbed site and an undisturbed site in a montane subtropical forest in northwestern Argentina. We found no overall difference in daily pr...
Article
The life history of figs (Ficus, Moraceae) involves pollination by specialized insects and seed dispersal by vertebrate frugivores. This three-way interaction raises the possibility of conflict between pollinators and seed dispersers over fig resources. The conflict might be mediated in dioecious figs by the segregation of inflorescences with speci...
Article
Full-text available
The influence of seed dispersers on the evolution of fruit traits remains controversial, largely because most studies have failed to account for phylogeny and or have focused on conservative taxonomic levels. Under the hypothesis that fruit traits have evolved in response to different sets of selective pressures by disparate types of seed disperser...
Article
Full-text available
Predators that live in environments with variable prey availability should be capable of modifying their behaviour in order to maximize their consumption rate. Sit-and-wait predators that use passive traps should modify trap architecture depending on the local conditions of prey availability. We quantified the short-term behavioural response of Myr...

Mediante un enfoque integral de las distintas etapas reproductivas de las plantas, y de las interacciones mutualistas y antagonistas en las que participa, intento entender el rol de las interacciones en el fitness de plantas de un bosque subtropical. Through a wholistic approach of the different reproductive stages of plants, and the mutualistic and antagonistic interactions in which plants are involved, I seek to understand the role of interactions plant fitness in a subtropical forest.
