A fine‐scale phylogenetic assessment of digenean trematodes in central Alberta reveals we have yet to uncover their total diversity

open access: yesEcology and Evolution, Volume 9, Issue 6, Page 3153-3238, March 2019., 2019
This manuscript represents a large, single, collective examination of larval trematodes from snail hosts, using molecular markers and phylogenetic methods. We contribute 1,091 mitochondrial sequences (cox1 and nad1) that represent 79 species from 23 genera and eight families.

Metacercarial Infection of Wild Nile Tilapia (Oreochromis niloticus) from Brazil

open access: yesThe Scientific World Journal, Volume 2014, Issue 1, 2014., 2014
Fingerlings of Oreochromis niloticus collected in an artificial urban lake from Belo Horizonte, Minas Gerais, Brazil, were evaluated for natural infection with trematodes. Morphological taxonomic identification of four fluke species was performed in O. niloticus examined, and the total prevalence of metacercariae was 60.7% (37/61).

Ecological Gradients Influencing Waterbird Communities in Black Water Lakes in the Anavilhanas Archipelago, Central Amazonia

open access: yesInternational Journal of Ecology, Volume 2012, Issue 1, 2012., 2012
For the first time, and in a large spatial scale, the influence of ecological properties on the aquatic bird community of black water lakes in Brazilian Amazonia is evaluated. Bird surveys were conducted in 45 lakes. A total of 3626 individuals in 48 bird species were recorded; of these, 31 are aquatic, and 18 of these are primarily piscivorous.

Integrating curimba culture during the grow‐out phase of tambaqui affects overall productivity, water quality, and fish health

open access: yesJournal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.
Abstract The efficiency of feed use in aquaculture may be improved by integrating the culture of extractive species into fed‐species systems. This study assessed the impact of including curimba (Prochilodus lineatus) in tambaqui (Colossoma macropomum) production during the grow‐out phase in earthen ponds.
