TRY plant trait database – enhanced coverage and open accessNARA Subscribed
Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research spanning from evolutionary biology, community and functional ecology, to biodivers...
The dimensionality of ecological networksNARA Subscribed
How many dimensions (trait‐axes) are required to predict whether two species interact? This unanswered question originated with the idea of ecological niches, and yet bears relevance today for understanding what determines network structure. Here, we analyse a set of 200 ecological networks, including food webs, antagonistic and mutualistic networks, and find that the number of dimensions needed to completely explain all inter...
Stepping in Elton’s footprints: a general scaling model for body masses and trophic levels across ecosystemsNARA Subscribed
Ecology Letters (2011) 14: 169–178 Abstract Despite growing awareness of the significance of body‐size and predator–prey body‐mass ratios for the stability of ecological networks, our understanding of their distribution within ecosystems is incomplete. Here, we study the relationships between predator and prey size, body‐mass ratios and predator trophic levels using body‐mass estimates of 1313 predators (invertebrates, ectothe...
