- 应用了网络分析指标,包括模块化,专业化和嵌套性.
- 网络中的宿主和寄生虫角色被分类 (例如,超外围,外围,省级枢纽).
主要成果:
- 一个由80种线虫小哺乳动物记录组成的网络是由52个文章构建的,其中24种与Didelphimorphia和56种与Rodentia相关.
- 该网络显示出显著的模块化,但缺乏整体专业化和嵌套性,尽管在模块内和整个网络中观察到嵌套模式.

Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...

Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...
