Elevational Gradients Shape Bee Network Structure and Community Composition Across Tropical Lowland to Montane Forests in Costa Rica
Mutualistic networks, such as those between plants and pollinators, play a crucial role in ecosystem stability and resilience. Previous theoretical work has posited that mutualistic networks with higher diversity, connectance, nestedness, interaction diversity and more generalist species are more …

Network structure and stability criteria for complex ecological systems
… influenced by the structure of the interaction networks. In the case of mutualistic networks, the nested structure often found in nature, has been shown to make the system less locally stable. Here, we consider two different ecological models. The first is a model of evolution in a mutualistic …

Fruits and frugivory in neotropical primates and in Amazonian flooded and unflooded forests
… Of particular interest in this regard are the mutualistic networks between fruiting plants and vertebrate frugivores, whose interdependent relationship is fundamental to the functioning of tropical forests. This thesis examined these fruitfrugivore interactions at two contrasting scales, and …

Understanding the role and impact of introduced honey bees in a submontane indigenous forest ecosystem
… analysis highlighted structural differences in networks between high and low hive density sites in terms of connectance, nestedness, and species-level indices. High and low hive density sites had a similar number of species that were native and non-native, but high hive density sites had more …
