Thermal preference, tolerance, and thermal aerobic scope in clownfish Amphiprion ocellaris (Cuvier, 1830) predict its aquaculture potential across tropical regions

open access: yesInternational Aquatic Research, 2019
The clownfish Amphiprion ocellaris is widely distributed in the coral reef ecosystems of tropical and subtropical regions of the West Indo Pacific, an area that hosts economically valuable species, and, thus, a suitable candidate for warm water ...

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

open access: yesMolecular Ecology, Volume 32, Issue 9, Page 2219-2233, May 2023., 2023
Abstract 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.

Exploring metapopulation‐scale suppression alternatives for a global invader in a river network experiencing climate change

open access: yesConservation Biology, Volume 37, Issue 1, February 2023., 2023
Abstract Invasive species can dramatically alter ecosystems, but eradication is difficult, and suppression is expensive once they are established. Uncertainties in the potential for expansion and impacts by an invader can lead to delayed and inadequate suppression, allowing for establishment.

Influence of water quality on the macroinvertebrate community in a tropical estuary (Buenaventura Bay)

open access: yesIntegrated Environmental Assessment and Management, Volume 18, Issue 3, Page 796-812, May 2022., 2022
Abstract The anthropogenic discharges of inorganic nutrients impact water quality, affecting the macroinvertebrate assemblage and food safety. The main objective of this study was to examine the seawater quality and macroinvertebrate dynamics in muddy habitats of Buenaventura Bay, Colombian Pacific.

Effects of human footprint and biophysical factors on the body‐size structure of fished marine species

open access: yesConservation Biology, Volume 36, Issue 2, April 2022., 2022
Abstract Marine fisheries in coastal ecosystems in many areas of the world have historically removed large‐bodied individuals, potentially impairing ecosystem functioning and the long‐term sustainability of fish populations. Reporting on size‐based indicators that link to food‐web structure can contribute to ecosystem‐based management, but the ...

INVENTARIO DE LARVAS DE PECES REGISTRADAS PARA EL CARIBE COLOMBIANO

open access: yesBulletin of Marine and Coastal Research, 2016
A taxonomic checklist of larval stages of fish species recorded in the Colombian Caribbean is presented, as a product of an extensive literature review of studies on the topic. Eighty five family records included in 21 orders, with a total of 129 species were found. In terms of composition, the order Perciformes has shown the highest number of families

Amazonian fish migration as a social–cultural–ecological process

open access: yesPeople and Nature, Volume 7, Issue 12, Page 3297-3312, December 2025.
Abstract In this study, we highlight the rich perspectives and explanations of fish migration held by Indigenous groups across the Amazon. We present the aspects of Indigenous cosmological stories, drawing from our exploratory review of cultural ethnographies and grey literature, as well as the authors' own experiences. We ask, how do Amazonian peoples
