摘      要：The introduction of species is a leading cause of biodiversity loss and habitat *** species have invaded Mexican freshwater ecosystems,adversely affecting native ***,in the Amacuzac River of the Balsas Basin(Central Mexico),at least four non-native cichlids have been recorded:tilapia Oreochromis sp.,convict cichlid Amatitlania nigrofasciata,spotcheek cichlid Thorichthys maculipinnis,and green terror Andinoacara *** species co-occur with the Mexican mojarra Amphilophus istlanus,the only native cichlid in the *** cichlids compete for resources such as shelter and food,and prey on offspring of the Mexican *** the presence of invasive cichlids,the costs and risks of foraging and finding available shelter increase for the native *** pressure from invasive cichlid fishes on the Mexican mojarra increases the time invested by parents in caring for offspring and their stress levels,potentially contributing to Mexican mojarra population ***,we gathered the best evidence available to discuss some mechanisms and consequences of such co-occurrences in relation to reproductive behaviors,parental care,competition for resources,and dominance hierarchy,and how the four invasive cichlids have negatively affected the Mexican mojarra.
