Based on original data gathered from fieldwork during the last years and from previous records from all published accounts, a checklist of the adult nematode parasites of freshwater fishes from Mexico is presented. The checklist is organized as a nematode-host list and comprises taxonomic and geographic distributional information. In total, the checklist includes 70 taxa (50 identified at species level) pertaining to 13 families. These taxa have been collected from 107 freshwater fish taxa in 198 localities along the Mexican Republic. The information we provide herein indicates that sampling effort has been concentrated in Central and South East Mexico, with the Northern region remaining mostly unexplored. The proportion of endemic nematodes is high in the country (74%, i.e., 37 of the 50 taxa identified at species level). The family Rhabdochonidae displays the highest species richness (12 species), and Rhabdochona kidderi is the most widespread nematode species in the country. Cichlids represent the host group with the largest number of samples in Mexico. Finally, we present a list containing new records of larval nematodes from localities in the states of Michoacán, Nayarit, Oaxaca, Tamaulipas and Veracruz.

The confinement of small amounts of toluene demonstrated an enhanced CO2 capture for InOF-1 as a result of a bottleneck effect and synergistic interactions.
