What does this research mean for the field?

Anthropogenic changes, including river dam construction, agricultural water demand, and groundwater depletion, have fundamentally reshaped the flow regime of Southern Great Plains rivers, leading to a decline in native fish assemblages and an increase in invasive species. Novelty: ClaimNovelty.SYNTHESIS. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Synthesize the ecological impacts of anthropogenic disruptions, including dam construction and groundwater depletion, on Southern Great Plains river systems and propose targeted conservation strategies.

Implication

Ecological review reveals severe riverine biodiversity loss and habitat fragmentation in the Southern Great Plains, highlighting the urgent need for flow restoration and conservation.

Key Points

Synthesize the ecological impacts of anthropogenic disruptions, including dam construction and groundwater depletion, on Southern Great Plains river systems and propose targeted conservation strategies.
Narrative review synthesizing regional hydrological and ecological literature across the Southern Great Plains.
Evaluated historical flow variability and evolutionary adaptations of endemic aquatic species alongside contemporary human-driven habitat modifications.
Dam construction, intensive agricultural water extraction, and groundwater depletion fundamentally altered regional flow regimes.
Human-driven alterations modified sediment transport, reduced microhabitat diversity, altered channel morphology, and increased habitat fragmentation.
Degraded riverine conditions precipitated widespread declines in native fish assemblages while promoting the proliferation of invasive species.
