Anthropogenic activities are the main cause of habitat loss and fragmentation, which directly affects biodiversity. Disruption in landscape connectivity among populations may affect complex interactions between species and ecosystem functions, such as pollination and seed dispersal, and ultimately result in secondary extinctions. Urbanization, one of the most intense forms of landscapes changes, has been reported to negatively affect bird and plant diversity. Still, little is known about the eff...

One of the major challenges in ecology is to understand the relative importance of neutral- and niche-based processes structuring species interactions within communities. The concept of neutral-based processes posits that network structure is a result of interactions between species based on their abundance. On the other hand, niche-based processes presume that network structure is shaped by constraints to interactions. Here, we evaluated the relative importance of neutral-based process, represe...

ABSTRACTDespite alleged advantages of organic over conventional farming, management effects on biodiversity are still little known. We related the diversity of herbs and flower visitors to management indicators in avocado orchards and hypothesized that inputs, practices, and context influence diversity of herbs and flower visitors. Using basic classification units, matrix correlation, and multivariate analysis of variance, we found that low-toxicity insecticides, infrequent herb cutting, and pre...

The system consisting of the plant Passiflora caerulea , the ants that visit its extrafloral nectaries and the larvae of the Gulf fritillary butterfly ( Agraulis vanillae ) that feed on the plant provides an opportunity to explore the effect of one ecological interaction on another. The objective of this work was to study the effect of the mutualism between the ants and the plant on the antagonism between the butterfly larvae and the plant. The general hypothesis tested was that ants protect the...

En las comunidades ecologicas, las especies pueden participar de forma simultanea en interacciones interespecificas de distinto tipo (e.g., depredacion, polinizacion y dispersion), lo que implica que la ocurrencia de una interaccion pueda afectar el resultado de otra. Una oportunidad para explorar el efecto de una interaccion ecologica sobre otra la brinda el sistema formado por la planta Passiflora caerulea , las hormigas que visitan sus nectarios extraflorales y las larvas de la mariposa Espej...

Seasonal turnover in plant and floral visitor communities changes the structure of the network of interactions they are involved in. Despite the dynamic nature of plant–visitor networks, a usual procedure is to pool year-round interaction data into a single network which may result in a biased depiction of the real structure of the interaction network. The annual temporal dynamics and the effect of merging monthly data have previously been described for qualitative data (i.e. describing the occu...

Summary 1. The ongoing biodiversity crisis entails the concomitant loss of species and the ecological services they provide. Global defaunation, and particularly the loss of frugivores, may negatively affect the seed dispersal of fleshy-fruited plant species, with predictable stronger impacts in simplified communities such as those on oceanic islands. However, logistical difficulties have hindered the experimental and theoretical need to disentangle the roles of species identity, richness (i.e. ...

Geographical gradients are useful tools for studying how changing environmental conditions affect communities’ structure and function, and any perceived general pattern can be tested by examining the response of different populations of a given species widely distributed along the focal gradient. We studied populations of the perennial, putatively entomophilous plant Discaria chacaye located along a strong east–west rainfall gradient in the north-west of Patagonia, Argentina, where a significant...
