REDUCING THE DIMENSIONALITY OF SPECIES DIVERSITY WITH FLOW RESPONSE GUILDS AND GENETIC TRAIT SYNDROMES
Biologists revel in the biodiversity of the world, but biodiversity can be a headache for management. How do we manage ecosystems that contain a diverse array of species, potentially with conflicting management needs? This study explores how traits can simplify diverse communities into groups that respond similarly to river flows and groups that have characteristic landscape genetic patterns. Flow-response traits were used to simplify diverse riparian plant communities into five guilds, and vegetation response was modeled under a variety of flow management scenarios. The model predicted high diversity and healthy community structure under natural flow regime, but loss of diversity with increasing drought or flood removal. To explore traits and genetic structure, landscape genetic patterns were characterized for three aquatic insects that spanned a diversity of ecohydrologic trait states. The three species had distinct landscape genetic patterns including nearly-complete isolation, to isolation-by-distance, and total panmixia. These distinct genetic trait syndromes lead logically to different management practices, with spatial connectivity benefitting some species but potentially harming others.
