Realistic nitrate concentrations diminish reproductive indicators in , an endemic species in critical endangered status.

Goodeinae is a subfamily of critically endangered fish native to central Mexico. Populations of , a species belonging to this subfamily, have significantly decreased in the past two decades. A previous study showed that is sensitive to acute nitrate-nitrogen (NO-N) exposure, leading to noticeable changes in both behavioral and histopathological bioindicators.

Environmental Degradation in a Eutrophic Shallow Lake is not Simply Due to Abundance of Non-native Cyprinus carpio.

Non-native species are often major drivers of the deterioration of natural ecosystems. The common carp Cyprinus carpio are known to cause major changes in lentic systems, but may not be solely responsible for large scale changes in these ecosystems. We used data from extensive collection efforts to gain insight into the importance of carp as drivers of ecosystem change in Lake Patzcuaro, Mexico.
