Analysis and Assembling of Network Structure in Mutualistic Systems [PDF]

, 2007
It has been observed that mutualistic bipartite networks have a nested structure of interactions. In addition, the degree distributions associated with the two guilds involved in such networks (e.g.

Evolution of Plant–Animal Interactions [PDF]

, 2010
The evolution of plant–animal interactions goes back to the Early Archean, when the first signals of photosynthesis may have been detected in the Isua Peninsula in Greenland, a phenomenon that is related to the isotopic anomalies of carbon.

Population structure, aggregation, and dispersal of Euterpe edulis Mart. at two sites of interior atlantic forest

Anais da Academia Brasileira de Ciências, 2023
Habitat destruction and fragmentation can change environmental conditions and disrupt mutualistic interactions, leading to impacts on natural populations. Here we checked how plant population structure responds to environmental degradation by quantifying

Shrubs indirectly increase desert seedbanks through facilitation of the plant community [PDF]

, 2019
The mechanisms supporting positive ecological interactions are important. Foundation species can structure desert biodiversity by facilitating seedbanks of annual plants, but the direct and indirect mechanisms of shrub effects on seedbank have not been ...

Highland barley grain and soil surveys reveal the widespread deficiency of dietary selenium intake of Tibetan adults living along Yalung Zangpo River

Frontiers in Sustainable Food Systems, 2022
ObjectiveIn order to assess selenium (Se) flux through the soil-plant-human chain in Tibet plateau and explore the reason why local Tibetan adult residents from large scale agricultural production areas in Tibet lacked daily Se intake.MethodsA total of ...

The restoration of ecological interactions: plant-pollinator networks on ancient and restored heathlands [PDF]

, 2008
1. Attempts to restore damaged ecosystems usually emphasize structural aspects of biodiversity, such as species richness and abundance. An alternative is to emphasize functional aspects, such as patterns of interaction between species.

The woodrat gut microbiota as an experimental system for understanding microbial metabolism of dietary toxins

Frontiers in Microbiology, 2016
The microbial communities inhabiting the alimentary tracts of mammals, particularly those of herbivores, are estimated to be one of the densest microbial reservoirs on Earth.

Arboreal twig-nesting ants form dominance hierarchies over nesting resources. [PDF]

, 2019
Interspecific dominance hierarchies have been widely reported across animal systems. High-ranking species are expected to monopolize more resources than low-ranking species via resource monopolization. In some ant species, dominance hierarchies have been

Ruminal microbiota–host interaction and its effect on nutrient metabolism

Animal Nutrition, 2021
Rumen microbiota has a close and intensive interaction with the ruminants. Microbiota residing in the rumen digests and ferments plant organic matters into nutrients that are subsequently utilized by the host, making ruminants a unique group of animals ...

Geographic patterns in plant-pollinator mutualistic networks [PDF]

, 2002
. Recent reviews of plant–pollinator mutualistic networks showed that gen- eralization is a common pattern in this type of interaction. Here we examine the ecological correlates of generalization patterns in plant–pollinator networks, especially how ...
