Reduced genetic diversity and the success of the invasive peacock bass (Cichliformes: Cichlidae).
TLDR
Overlapping morphological data and similar coloration patterns prevented their identification using the taxonomic keys to species identification, but Bayesian and maximum likelihood from sequencing data demonstrated the occurrence of a single species, Cichla kelberi.
Changes in ecosystem functions generated by fish populations after the introduction of a non-native predator (Cichla kelberi) (Perciformes: Cichlidae)
TLDR
Evidence is provided that community disassembly associated with the invasion of C. kelberi translated to the decline of several ecosystem functions, affecting energy mobilization and transference, suggesting that the loss of taxa and biomass drove observed changes in ecosystem functions.

Neotropical freshwater ecosystems are experiencing a great expansion in the number of invasive species, which is especially alarming since this region harbours 30% of the world’s fish biodiversity
Fish fauna destruction after the introduction of a non-native predator (Cichla kelberi) in a Neotropical reservoir
TLDR
Results from this natural experiment provided evidence supporting the collapse of fish assemblages soon after the introduction of C. kelberi, revealing an important homogenizing force behind this predator and stresses the need for control measures that prevent new transferences among South American basins.
Predicting impact of freshwater exotic species on native biodiversity: Challenges in spatial scaling
TLDR
This work addresses the issue of management of freshwater exotic species on lakes or drainages that are both vulnerable to colonization by an exotic, and that harbour endemic species, with different spatial scales of experiments testing the impact of two predators on native snail assemblages.
Food web changes associated with drought and invasive species in a tropical semiarid reservoir
TLDR
A typical reservoir in a Brazilian semiarid region is modeled using an ecosystem approach to compare the role of native and non-native invasive species (NIS) in the food web, between dry and wet periods, and under the influence of an extreme drought period, simulating the variation in fish biomasses due to decreasing consumption.
Ecological impacts of an invasive predator explained and predicted by comparative functional responses
TLDR
Comparative functional responses of recent and ecologically damaging invader Hemimysis anomala merit further exploration as a methodology for predicting severe community-level impacts of current and future invasive species and could be entered into risk assessment protocols.
Tropical fish community does not recover 45 years after predator introduction.
TLDR
Comparisons with historical data revealed that the peacock bass remains the most abundant predator in Lake Gatun, Panama, and the collapse of the littoral prey community observed immediately following the invasion has been sustained over the past 45 years.
The largemouth bass Micropterus salmoides (Lacepède, 1802): impacts of a powerful freshwater fish predator outside of its native range
TLDR
A systematic review of the literature using the ISI Web of Science and Scopus databases to synthesize the existing knowledge concerning introductions of M. salmoides and their ecological impacts highlights major trends and gaps related to spatiotemporal patterns of the publications, research methods and ecological impacts.
Dammed rivers: impoundments facilitate fish invasions
TLDR
A global meta-analysis of fish communities, comparing species richness, abundance and proportion of alien species between dammed and undammed rivers, suggests that the conversion of lotic waterbodies into lentic habitats result in the extirpation of species unable to withstand a drastic change in environmental conditions, but the loss is compensated by colonising lacustrine or eurytopic species.
Species Introduction in a Tropical Lake
TLDR
It will be some time before it can evaluate the permanence or transience of the many changes produced in the trophic levels by the introduction of a single, top-level predator to this lake system.
