Population dynamics of two Andean Trichomycterus (Siluriformes: Trichomycteridae) species from Bolivia [PDF]

Neotropical Ichthyology
The species of Trichomycterus (Siluriformes: Trichomycteridae) are small catfish distributed throughout South and Central America, from Patagonia to Costa Rica, at elevations ranging from sea level to over 4,000 m.

How does fragmentation by small dams affect stream ichthyofauna in the upper Paraná River basin? [PDF]

Neotropical Ichthyology
Since the seminal publication of the River Continuum Concept (RCC), many studies have shown the importance of habitat and longitudinal changes on fish distribution, including for the Neotropical region.

Hydraulic flow resistance of epigean and hypogean fish of the family Trichomycteridae (Ostariophysi, Siluriformes) [PDF]

Subterranean Biology, 2020
Critical swimming speeds of four trichomycterid fish species from epigean and hypogean environments were analyzed and compared: Trichomycterus itacarambiensis and Ituglanis passensis, both troglobitic from underground rivers; Trichomycterus brasiliensis, from epigean rivers; and Ituglanis sp., an undescribed troglophilic species from an underground ...

Evolutionary history of Middle American Rhamdia (Siluriformes: Heptapteridae) inferred from comparative mitogenomic data: Insights on historical biogeography and cave colonization in the group

Journal of Systematics and Evolution, Volume 63, Issue 6, Page 1501-1518, November 2025.
Investigating the systematics and biogeography of Neotropical catfishes of the genus Rhamdia refined phylogenetic hypotheses, including deep paraphyly of Rhamdia laticauda, supported northward dispersal catalyzed by emergence of the Panamanian Isthmus and imply that cave colonization is widespread, convergent, and recent, with established cave‐dwelling

Selective foraging by non-native rainbow trout on invertebrates in Patagonian streams in Argentina [PDF]

, 2015
Background It is well known that fish predation alters ecosystem processes by top-down effects. Salmonids are described as aggressive, visually and size-selective predators. Thus, prey selection by the non-native rainbow trout was examined on a seasonal

Parasites Are Paramount: Vertical Trophic Positions of Parasitic Catfishes in a Tropical River Food Web

Ecology of Freshwater Fish, Volume 34, Issue 4, October 2025.
ABSTRACT The Neotropical catfish family Trichomycteridae contains parasitic fishes that include scale and mucus feeders (subfamily Stegophilinae) and blood feeders (i.e., ‘candirus’, subfamily Vandelliinae). The influence of parasitic catfishes on food web dynamics is unknown.
