Brazilian Archives of Biology and Technology, 2006 The present study was conducted to determine if parasite induced mortality existed in a "puyen" population in Moreno Lake, southern Argentina. Data on both parasite abundance and degree of aggregation of parasite frequency distribution showed the absence

Fishing‐Induced Regulation of Diadromous Fish Subsidies in Stream Communities
Freshwater Biology, Volume 71, Issue 1, January 2026.ABSTRACT Seasonal migrations of diadromous fish transport marine‐derived nutrients into freshwater ecosystems, enriching communities and restructuring food‐web dynamics. By diminishing these migrations, fishing pressure could disrupt cross‐ecosystem connectivity, thereby altering predator–prey interactions and community size structure.

Diversity and Distributions, Volume 31, Issue 11, November 2025.ABSTRACT Aim Invasive species can affect native species detrimentally, causing localised population declines, range contractions and extinctions. Given the costs and difficulties of controlling invasive species, sound knowledge of the potential benefits to native species is essential.
