Frugivory and Seed Dispersal by Lizards: A Global Review

open access: yesFrontiers in Ecology and Evolution, 2019
Birds and mammals are the only vertebrates which receive comprehensive attention in studies of dispersal of fleshy-fruited plant species. However, recently the importance of fleshy fruit in the diet of lizards (order Squamata: suborder Sauria), and their

Phylogenomics and analysis of shared genes suggest a single transition to mutualism in Wolbachia of nematodes [PDF]

open access: yes, 2013
Wolbachia, endosymbiotic bacteria of the order Rickettsiales, are widespread in arthropods but also present in nematodes. In arthropods, A and B supergroup Wolbachia are generally associated with distortion of host reproduction.

The joint influence of competition and mutualism on the biodiversity of mutualistic ecosystems [PDF]

open access: yes, 2017
Relations among species in ecosystems can be represented by complex networks where both negative (competition) and positive (mutualism) interactions are concurrently present.

Phylogenetic and Functional Diversity of Fleshy-Fruited Plants Are Positively Associated with Seedling Diversity in a Tropical Montane Forest

open access: yesFrontiers in Ecology and Evolution, 2017
Mutualistic interactions between plants and animals can affect both plant and animal communities, and potentially leave imprints on plant demography. Yet, no study has simultaneously tested how trait variation in plant resources shapes the diversity of ...

Gut microbiota as a trigger of accelerated directional adaptive evolution. Acquisition of herbivory in the context of extracellular vesicles, microRNAs and inter-kingdom crosstalk [PDF]

open access: yes, 2017
According to a traditional view, the specific diet in vertebrates is one of the key factors structuring the composition of the gut microbiota. In this interpretation, the microbiota assumes a subordinate position, where the larger host shapes, through ...

Ant-plant interaction in a tropical savanna: may the network structure vary over time and influence on the outcomes of associations? [PDF]

open access: yesPLoS ONE, 2014
Plant-animal interactions occur in a community context of dynamic and complex ecological interactive networks. The understanding of who interacts with whom is a basic information, but the outcomes of interactions among associates are fundamental to draw ...

Reconciling cooperation, biodiversity and stability in complex ecological communities [PDF]

open access: yes, 2018
Empirical observations show that ecological communities can have a huge number of coexisting species, also with few or limited number of resources. These ecosystems are characterized by multiple type of interactions, in particular displaying cooperative ...

The olfactory basis of orchid pollination by mosquitoes. [PDF]

open access: yes, 2020
Mosquitoes are important vectors of disease and require sources of carbohydrates for reproduction and survival. Unlike host-related behaviors of mosquitoes, comparatively less is understood about the mechanisms involved in nectar-feeding decisions, or ...

Emergence of structural and dynamical properties of ecological mutualistic networks

open access: yes, 2013
Mutualistic networks are formed when the interactions between two classes of species are mutually beneficial. They are important examples of cooperation shaped by evolution.

Complementary Effects of Species Abundances and Ecological Neighborhood on the Occurrence of Fruit-Frugivore Interactions

open access: yesFrontiers in Ecology and Evolution, 2017
Species interactions are traditionally seen as the outcome of both ecological and evolutionary mechanisms. Among them, the two most frequently studied are the neutral role of species abundances in determining encounter probability and the deterministic ...
