Development of microsatellite markers for Hoplias malabaricus (Erythrinidae).

open access: yesGenetics and molecular research : GMR, 2010
We identified 14 microsatellite loci for the wolf fish, Hoplias malabaricus (Erythrinidae), from a genomic shotgun library. Twenty-five primers were designed, and 48 individuals of H. malabaricus from four localities of northwest Goiás, in central Brazil, were genotyped to characterize the polymorphism at each locus.

Larger Fish Upstream: Testing the Drivers of Fish Longitudinal Size Distribution in a Stream

open access: yesFreshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT The “larger fish upstream pattern” (LFUP), where fish size increases from river mouths toward headwaters, is widely documented, but the drivers remain unclear. Here, we tested whether LFUP is related to species reproductive strategies or environmental factors (differential growth, predation, competition). Using historical data (1994–1998) from
