| dc.description.abstract | THE SOUTHERN HUMBOLDT CURRENT ECOSYSTEM IS AN IMPORTANT TOPIC AMONG RESEARCHERS WORKING ON THE DRIVERS OF PELAGIC SPECIES BIOLOGICAL INDICATORS. WHILE SEA SURFACE TEMPERATURE IS BELIEVED TO BE A MAJOR DRIVER IN ANCHOVIES (ENGRAULIS RINGENS) REPRODUCTIVE AND BODY CONDITION INDICATORS, THIS PAPER SHOWS THAT REGIONAL DRIVERS SUCH AS PACIFIC DECADAL OSCILLATION ANOMALIES ALSO INFLUENCE THESE BIOLOGICAL PROCESSES. IN ADDITION, A WARM CONDITION COULD TRIGGER INCREASED GONAD DEVELOPMENT OF ANCHOVIES AND SYNCHRONIZATION OF BODY CONDITION DYNAMICS WITH LOCAL ENVIRONMENTAL CONDITIONS STEMMING FROM SEA TURBULENCE AND EKMAN TRANSPORT. TO TEST THE STATISTICAL SIGNIFICANCE OF CAUSALITY BETWEEN TWO TIME SERIES AND DETERMINE THE DIRECTION OF CAUSALITY, THE FREQUENCY-DOMAIN GRANGER-CAUSALITY METHOD IS CONSIDERED. THEREFORE, THIS STUDY PROVIDES ADDITIONAL PREDICTIVE INFORMATION, DERIVED FROM PAST DATA ON ANCHOVY REPRODUCTIVE AND FEEDING ACTIVITIES. THE STUDY COULD BE USEFUL FOR RESEARCHERS WORKING ON RELATIONSHIPS OF ENVIRONMENTAL CONDITIONS AND PELAGIC SPECIES TO PREDICT BIOLOGICAL PROCESSES MAXIMUM AND MINIMUM PEAK MOVEMENTS AND ANCHOVY ABUNDANCE IN THE SOUTHERN HUMBOLDT CURRENT ECOSYSTEM. | |
