Empirical evidence has shown that introduced honeybees, Apis mellifera L., can change the structural organization of ecological networks involving pollinators and flowering plants. In this case, studies have shown that A. mellifera is highly connected within networks (i.e., high interactive role) mainly due to its high abundances, long colony lifet...

Despite increasing knowledge of the ecological interactions between species, the dynamics of anurans in aquatic environments are little explored. Thus, our work aims to assess which factors influence the composition and the ecological interactions of hylid anuran species in oxbow lakes in the middle Purus River, Amazonas state, Brazil. We sampled h...

Ants, an ecologically successful and numerically dominant group of animals, play key ecological roles as soil engineers, predators, nutrient recyclers, and regulators of plant growth and reproduction in most terrestrial ecosystems. Further, ants are widely used as bioindicators of the ecological impact of land use. We gathered information of ant sp...

Full-text available
Trophic specialisation is known to vary across space, but the environmental factors explaining such variation remain elusive. Here we used a global dataset of flower-visitor networks to evaluate how trophic specialisation varies between latitudinal zones (tropical and temperate) and across elevation gradients, while considering the environmental va...

Chapter
Animals and plants are involved in a great number of trophic relationships that are responsible for the origin, maintenance and function of biodiversity. This great number of interactions between animals and plants gives rise to large and complex networks of ecological interactions. In the past few decades, the study of plant-animal interaction net...
Article
1. The factors that drive resource removal by insect predators hold the clue to understanding their role in structuring ecological communities and their evolution. Harvester ants are formidable seed predators and invertebrate carcass feeders. However, the extent to which neutral and niche‐based factors drive the selection and removal of preferred f...
Article
Understanding the impacts of edge effects on ecological interactions plays an integral role in planning ecosystem recovery from human perturbations, as well as conservation of habitats. Edge effects related to forest fragmentation cause changes in species diversity that can disrupt ecological networks. Here, we evaluated how the diversity of, and i...

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropica...

En este articulo hablamos del proceso de polinización, dispersión de semillas y de la crisis mundial de polinizadores.
Article
Full-text available
To reduce herbivory, plants bearing extrafloral nectaries interact with ants and attract them by providing food. As plant bodyguards, ants respond to the resource provision and, using their antennae, detect chemical messages from the host plants that help them to locate herbivores. Ants can also use their vision to explore the environment; however,...
Article
Full-text available
Butterfly species often synchronize their life cycles to seasonality, as increasing temperature and rainfall act as clues of resource availability. Nevertheless, human-made forest edges cause major changes in the microclimatic conditions that may jeopardize the synchrony between insects and favorable conditions for their emergence, conversely to na...

A team of 79 scientists from more than 50 institutions partnered to gather all available information regarding Mexican ants since 1894, the year in which the first geographical record of an ant is known for the country. In this new study, including more than 21,000 records, we showed that there are ~900 species of ants in Mexico, which are distribu...

Biotic interactions are part of all ecosystem attributes and play an important role in the structure and stability of biological communities. In this study, we give a brief account of how the threads of biotic interactions are linked and how we can measure such complexity by focusing on mutualistic interactions. We start by explaining that although...
Article
In tropical forests, twigs are the nesting resources most frequently occupied by ants in the leaf litter. During occupation, this resource may be shared among different arthropods, such as ants or non-ant arthropods, but the mechanisms that promote cohabitation in this context are poorly known. In this study, we examined if twig structure influence...
Preprint
In this data paper, we compiled all the available published and unpublished geographic information (including both incidence and abundance records) about native and exotic ant species recorded within Mexico over 124 years (from 1894–2018). After exhaustive filtering, the updating of information and the curation of synonyms, our data set contains 21...
Article
Full-text available
Mexico is one of the most biodiverse countries in the world, with an important proportion of endemism mainly due to the convergence of the Nearctic and Neotropical biogeographic regions, which generate great diversity and species turnover at different spatial scales. However, most of our knowledge of the Mexican ant biota is limited to a few well‐s...
Article
Full-text available
Social insects utilise a complex spatial orientation system mediated by chemical signals. This study investigated how the foraging behavior of ants (Dorymyrmex thoracicus) varies depending upon the quantity of an available resource using a field experiment. Further, we demonstrated computationally that ant displacement is compatible with a model ba...

1. Harvester ants perform important ecological functions, such as seed predation and redistribution of nutrients in the soil, through a complex of ecological interactions. Most studies are static descriptions of network structure, while their temporal organisations and the factors that modulate it have been neglected. 2. This study describes the te...
Article
Full-text available
Twig cavities are microhabitats that may be used by different ant species for nesting and colony expansion. However, ants do not colonize all twigs available in the leaf litter, pointing to the existence of environmental or twig-related filters. In this study, we analyzed which environmental and twig attributes affected twig occupation by ants. We...
Article
Despite the increasing number of studies dealing with interaction networks in the last few years, there is still a lack of knowledge about how their structural organization are affected by changes in binary or weighted data. To fill this gap, we collected ants foraging on plants with extrafloral nectaries in 10 sites within the Brazilian Amazon to...
Article
Full-text available
The preferences of seed intake by harvester ants (Pogonomyrmex spp.) have been debated for a long time, mainly due the lack of repeatable methods to draw clear conclusions. However, several characteristics of the food resource are well recognized as the drivers of such selective predation. For instance, resource quality (i.e., availability of carbo...
Article
Despite the growing knowledge regarding biotic interactions, the diversity and turnover of species interactions is one of the least understood and explored components in studies dealing with species interaction networks. Since the spatial and temporal distribution of animals and plants is unequal, their pairwise interactions are also expected to va...
Article
Granivory is an important interaction in the arid and semi-arid zones of the world, since seeds form an abundant and nutritious resource in these areas. While species of the genus Pogonomyrmex have been studied in detail as seed predators, their impact on seed abundance in the soil has not yet been explored in sufficient depth. We studied the impac...

Full-text available
In the last years, there were a growing number of studies using the metric H 2' to calculate complementary specialization in host-parasite interaction networks. However, only a few studies have explored the sensitivity of H 2' to network dimensions (i.e. species richness and number of interactions), which consequently could generate studies that ar...
Article
Full-text available
Mainly owing to their high diversity and abundance, ants are formidable as predators and defenders of foliage. Consequently, ants can exclude both invertebrate and vertebrate activity on plants via direct and indirect interactions as already shown in many previous studies. Here we present empirical evidence that objects resembling ant shape on dumm...

Project
We aim to investigate ecological-evolutionary aspects regarding the interactions between Pogonomyrmex species and their food resources (both seeds and invertebrates). Through continental experiment, we will investigate (i) the influence of biotic traits of seeds (e.g., seed density and distance of seeds in relation to ant nests location) and abiotic factors (e.g., elevation and rainfall) on seed removal rates by Pogonomyrmex species and (ii) the organization of the Pogonomyrmex-food resources networks.
Project
We aim to understand the diversity of biopic interactions and which factors explain it, under a proper theoretical and methodological framework.
