Randomized trial investigates population traits and reproductive patterns in symbiotic species, indicating ecological adaptations.
Key Points
To investigate the population dynamics and reproductive traits of the pea crab and its ghost shrimp host, focusing on their interactions and environmental influences.
Monthly collections conducted over 1 year at Cinelândia Beach, Aracaju, Sergipe
Size-frequency distributions and sex ratios analyzed
Reproductive periods correlated with environmental factors
A. aidae showed continuous seasonal reproduction with peaks in June-August and April, influenced by precipitation
C. corruptus exhibited seasonal reproduction peaking in February, correlated with higher temperatures
A significant negative correlation was found between ovigerous female percentages of both species, indicating reproductive asynchrony
