Ingestion Rate, Prey Selectivity, and Growth of Larval Vieja zonata (Teleostei: Cichlidae) Co‐Fed Rotifers with Cladocerans [PDF]

open access: yesAquaculture Nutrition, Volume 2024, Issue 1, 2024.
The study of fish larval nutrition is important as dietary requirements change significantly with growth. Vieja zonata is a cichlid species that is endemic to Mexico. In this study, we investigated the ingestion rate, prey selectivity, and growth of V. zonata larvae that were fed on prey cultured with and without probiotics.

Competition from sea to mountain: Interactions and aggregation in low‐diversity monogenean and endohelminth communities in twospot livebearer Pseudoxiphophorus bimaculatus (Teleostei: Poeciliidae) populations in a neotropical river [PDF]

open access: yesEcology and Evolution, Volume 10, Issue 17, Page 9115-9131, September 2020., 2020
The results of this work suggest that interspecific competition can occur in species‐poor, nonsaturated communities among specialist dominant species. Our analyses suggest also that aggregation is an important factor to determine local richness of parasites in fish populations and that intraspecific aggregation allows the coexistence of species in the ...

The effects of temperature and flooding duration on the structure and magnitude of a floodplain prey subsidy

open access: yesFreshwater Biology, Volume 68, Issue 9, Page 1518-1529, September 2023., 2023
Abstract Riverine floodplains serve as an important link between terrestrial and aquatic systems, as the rising and falling of water drive spatial food web subsidies that are critical to the functioning and stability of ecosystems. As these systems are increasingly impacted by hydrological alterations and climate change, it is important to understand ...

The role of refuges in biological invasions: A systematic review

open access: yesGlobal Ecology and Biogeography, Volume 32, Issue 8, Page 1244-1271, August 2023., 2023
Abstract Aim Ecological refuges buffer organisms against stressors and mediate a range of species interactions. However, their role in the context of biological invasions has yet to be synthesized, despite the increasing prevalence and impact of non‐native species.

BioLake: A first assessment of lake temperature‐derived bioclimatic predictors for aquatic invasive species

open access: yesEcosphere, Volume 14, Issue 7, July 2023., 2023
Abstract Aquatic invasive species (AIS) present major ecological and economic challenges globally, endangering ecosystems and human livelihoods. Managers and policy makers thus need tools to predict invasion risk and prioritize species and areas of concern, and they often use native range climate matching to determine whether a species could persist in

Trophic ecology of co‐occurring fishes in the Sundays River Valley irrigation ponds, assessed using stable isotope and gut content analyses

open access: yesJournal of Fish Biology, Volume 102, Issue 5, Page 1191-1205, May 2023., 2023
Abstract The analysis of food web structures has increased the understanding of the dynamics of organisms belonging to different trophic levels. In this study, the diet of two native species, Glossogobius callidus and Gilchristella aestuaria, was assessed in the presence of two non‐native species, Oreochromis mossambicus and Gambusia affinis, in ...

A global review of problematic and pathogenic parasites of farmed tilapia

open access: yesReviews in Aquaculture, Volume 15, Issue S1, Page 92-153, February 2023., 2023
Abstract Over the past 80 years, tilapia have been translocated globally for aquaculture; active production is recorded in >124 countries. Of 7 million tonnes of tilapia produced in aquaculture, 79% is from 79 countries outside the natural range of tilapia.

Life history strategies differentiate established from failed non‐native freshwater fish in peninsular Florida

open access: yesDiversity and Distributions, Volume 28, Issue 1, Page 160-172, January 2022., 2022
Abstract Aim Non‐native fishes threaten native biodiversity worldwide. Life history traits have been used to predict the risk of establishment for non‐native fish in several regions of the world and parts of the United States, but not yet for Florida despite the elevated risk of establishment in the state due to many invasion pathways and favourable ...

Signal from the noise: model‐based interpretation of variable correspondence between active and passive samplers

open access: yesEcosphere, Volume 10, Issue 9, September 2019., 2019
Abstract Combining information from active and passive sampling of mobile animals is challenging because active‐sampling data are affected by limited detection of rare or sparse taxa, while passive‐sampling data reflect both density and movement. We propose that a model‐based analysis allows information to be combined between these methods to interpret

Knocking back invasions: variable resistance and resilience to multiple cold spells in native vs. nonnative fishes

open access: yesEcosphere, Volume 7, Issue 6, June 2016., 2016
Abstract Extreme climate events can interact synergistically with invasions to dramatically alter ecosystem structure, function, and services. Yet, the effects of extreme climate events on species invasions remain unresolved. Extreme climate events may increase resources and decrease biotic resistance by causing physiological stress and/or mortality of
