  abstract = {{I}dentifying ecological thresholds, which are critical points at which ecosystems undergo abrupt shifts in structure and function, has become a cornerstone of conservation and management strategies. {T}his study introduces a novel framework, the "ecological threshold spectrum", by integrating exploration, inference, and validation approaches, to address the limitations of existing methods. {T}he effectiveness of this analytical framework is demonstrated through a case study on fish communities in shallow eutrophic lakes located in the middle and lower reaches of the {Y}angtze {R}iver. {W}e analyzed phosphorus loading as a key driver of fish community and identified three critical ranges of total phosphorus ({TP}) using {G}radient {F}orest, {T}hreshold {I}ndicator {T}axa {A}nalysis and {B}oosted {R}egression {T}rees. {T}he first range, {TP} < 0.08 mg {L}-1, is characterized by submerged macrophyte dominance and high fish biodiversity. {T}he second range, {TP} between 0.08 and 0.12 mg {L}-1, represents a transitional phase with significant species and diversity loss. {T}he third range, {TP} between 0.12 and 0.17 mg {L}-1, is dominated by pollution-tolerant species and associated with severe turbidity. {W}e illustrate how the different analytical methods complement one another by capturing both species-specific and community-level responses to environmental gradients, thereby enabling more robust threshold identifications based on multiple response variables. {O}ur framework addresses uncertainties in ecological threshold detection by combining the strengths of multiple methods while accounting for data quality, noise, and species-specific masking effects. {T}he findings emphasize the importance of {TP} control in maintaining ecological stability and inform targeted restoration strategies at different eutrophication stages. {O}verall, the ecological threshold spectrum framework offers new insights into state transitions and provides a robust, practical approach to sustainable management.},
