Geomorphic river classifications based on different methods coincide in predicting fish assemblage structure

Camila Bañales‐Seguel, Konrad Górski, Alejandra Zurita, Aliro Manosalva et autres

Abstract River classification is a necessary starting point for understanding river ecosystems and developing management guidelines. Using GIS to analyse an Andean river basin, we compare the application of two geomorphic classification methods at the segment scale: The Geomorphic Units Survey Classification …

Trait Composition and Assemblage Structure Analyses of Lacustrine Fishes: Synthesizing a Proposal for Better Fishing Practices

Gustavo Díaz, Evelyn Habit, Roberto Urrutia, Aliro Manosalva et autres

Fish provide ecosystem services and contribute to human well-being through fishing. In Chile, subsistence fishing provides food to local communities, whereas recreational fishing contributes to economic income via tourism. In the Lanalhue coastal lake basin, unregulated subsistence fishing and formal recreational fishing …

Fragmentation Level Drives Local Fish Assemblage Diversity Patterns in Fragmented River Basins

Gustavo Díaz, Konrad Górski, Aliro Manosalva, Bárbara Arias Toledo et autres

Longitudinal connectivity is the main attribute of river ecosystems and is essential for the maintenance of aquatic biota. When longitudinal connectivity decreases in a river network, abundance of some fish species decreases, and local extinctions may occur. Such abundance decreases and extinctions …

Does the loss of diadromy imply the loss of salinity tolerance? A gene expression study with replicate nondiadromous populations of Galaxias maculatus

M. Lisette Delgado, Aliro Manosalva, Mauricio A. Urbina, Anne C. Dalziel et autres

The recurrent colonization of freshwater habitats and subsequent loss of diadromy is a major ecological transition that has been reported in many ancestrally diadromous fishes. Such residency is often accompanied by a loss of tolerance to seawater. The amphidromous Galaxias maculatus has …

Latitudinal and Altitudinal Gradients of Riverine Landscapes in Andean Rivers

Evelyn Habit, Alejandra Zurita, Gustavo Díaz, Aliro Manosalva et autres

Exact knowledge of the physical structures of different river sections that govern their ecological structure and function is essential for the efficient conservation and management of riverine ecosystems. Eleven Andean river basins (Maipo, Rapel, Mataquito, Maule, Itata, Biobío, Toltén, Valdivia, Bueno and …

Genomic basis of the loss of diadromy in Galaxias maculatus : Insights from reciprocal transplant experiments

M. Lisette Delgado, Aliro Manosalva, Mauricio A. Urbina, Evelyn Habit et autres

Diadromy is known for having major effects on the distribution and richness of aquatic species, and so does its loss. The loss of diadromy has led to the diversification of many species, yet research focusing on understanding its molecular basis and consequences …

Human‐induced habitat fragmentation effects on connectivity, diversity, and population persistence of an endemic fish, Percilia irwini, in the Biobío River basin (Chile)

Francisca Valenzuela‐Aguayo, Gregory R. McCracken, Aliro Manosalva, Evelyn Habit et autres

Abstract An understanding of how genetic variability is distributed in space is fundamental for the conservation and maintenance of diversity in spatially fragmented and vulnerable populations. While fragmentation can occur from natural barriers, it can also be exacerbated by anthropogenic activities such …
