Using Long‐Term Monitoring Data to Assess Temporal Patterns in Fish Community Assemblages in Florida Lakes

Fisheries Management and Ecology, EarlyView.
ABSTRACT In an effort to increase the relevancy of fish community data for management, we used fish community data to conduct a statewide assessment of Florida's freshwater fisheries resources and compare the relationships between environmental factors and freshwater fish communities over time.

Bony fish genomes: Status and gaps

Journal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

Rapid generation of ecologically relevant behavioral novelty in experimental cichlid hybrids

Ecology and Evolution, 2020
The East African cichlid radiations are characterized by repeated and rapid diversification into many distinct species with different ecological specializations and by a history of hybridization events between nonsister species.

High trophic niche overlap between sympatric peacock basses (Cichliformes: Cichlidae: Cichla): Concordant findings from three dietary analysis methods

Journal of Fish Biology, EarlyView.
Abstract Dietary analysis has contributed to our understanding of animal niches, interspecific interactions, community structure and the flow of matter and energy in food webs. We employed three methods of dietary analysis to estimate trophic niche overlap between two peacock bass species, Cichla cataractae and Cichla ocellaris, across sympatric ...

On the occurrence of three non-native cichlid species including the first record of a feral population of Pelmatolapia (Tilapia) mariae (Boulenger, 1899) in Europe [PDF]

Royal Society Open Science, 2017
Thermally influenced freshwater systems provide suitable conditions for non-native species of tropical and subtropical origin to survive and form proliferating populations beyond their native ranges.

Take my breath away: Defining the oxygen saturation threshold for fish cortisol stress response

Journal of Fish Biology, EarlyView.
Abstract Human activities are affecting the number, size and severity of hypoxic zones in aquatic ecosystems. As oxygen is one of the most important abiotic factors affecting fish biology, exposure to low levels of dissolved oxygen may lead to a reduction in fitness.

Ontogenetic diet shifts of Oreochromis niloticus and Tilapia rendalli of the Barra Bonita reservoir (Tietê river, São Paulo State, Brazil)=Mudanças ontogenéticas na dieta de Oreochromis niloticus and Tilapia rendalli da represa de Barra Bonita (rio Tietê, Estado de São Paulo, Brasil) [PDF]

Acta Scientiarum: Biological Sciences, 2012
The Nile Tilapia, Oreochromis niloticus, and the Congo Tilapia, Tilapia rendalli, are important members of the African cichlids, and have been introduced to many Brazilian lakes and reservoirs.

Impacts of predator odours and conspecific disturbance cues on minnow thermal tolerance

Journal of Fish Biology, EarlyView.
Abstract Warming waters can affect fish community dynamics, potentially exacerbating predator–prey asymmetries in behavioural and physiological metrics of thermal tolerance. Further, differing responses of prey fish species to concurrent predation risk and warming highlight the need to understand these impacts in various contexts, especially with at ...

Taxonomic inflation in fish systematics: A critical review with illustrative evidence assessment and integrative case study of the Salmo trutta Complex

Journal of Fish Biology, EarlyView.
Abstract Fish species are being described at an accelerating rate, but a substantial fraction of recent descriptions rests on evidentiary standards too weak to distinguish genuine species‐level discontinuities from intraspecific variation, local adaptation and the artefacts of single‐marker analyses, a pattern of taxonomic inflation with documented ...
