A new analysis of hypoxia tolerance in fishes using a database of critical oxygen level (Pcrit)
Data were compiled from the literature on the critical oxygen level (Pcrit), a hypoxia-tolerance trait, comprising 96 studies covering 151 fish species from 58 families. Salinity, temperature, bodyExpand

Energetic constraints on electric signalling in wave-type weakly electric fishes
SUMMARY Gymnotiform weakly electric fishes generate electric organ discharges (EODs) and sense perturbations of the resulting electric field for purposes of orientation, prey detection andExpand

Energetics of Hypoxia in a Mouth‐Brooding Cichlid: Evidence for Interdemic and Developmental Effects
We used a common‐garden rearing experiment to explore environmentally induced tolerance to hypoxia in the African mouth‐brooding cichlid Pseudocrenilabrus multicolor. F1 fish originating from threeExpand

Hypoxia and life-history traits in a eurytopic African cichlid.
This study quantified variation in key life-history traits of the widespread African mouth-brooding cichlid Pseudocrenilabrus multicolor victoriae. Egg size, number, batch reproductive effort, sizeExpand

Reproductive seasonality in a swamp-locked African cichlid
–  This study quantified the seasonal pattern of reproduction in a swamp-dwelling population of the African cichlid Pseudocrenilabrus multicolor victoriae. In the hypoxic waters of the LwamundaExpand

Critical swim speed and fast-start response in the African cichlid Pseudocrenilabrus multicolor victoriae: convergent performance in divergent oxygen regimes
Dissolved oxygen (DO) can be a strong predictor of intraspecific variation in morphology and physiology in fishes. In the African cichlid Pseudocrenilabrus multicolor victoriae Seegers, 1990, fishExpand

Brood protection at a cost: mouth brooding under hypoxia in an African cichlid
This study quantifies the behavioral response of the widespread mouth brooding African cichlid Pseudocrenilabrus multicolor victoriae to progressive hypoxia. We exposed four gender/stage classes ofExpand

Hypoxia and male behaviour in an African cichlid Pseudocrenilabrus multicolor victoriae.
This study tested the prediction that hypoxia may reduce the frequency of energetically expensive behaviours by quantifying male mating and aggressive displays in the cichlid PseudocrenilabrusExpand

Hypoxia and lost gills: respiratory ecology of a temperate larval damselfly.
Damselfly larvae, important predators and prey in many freshwater communities, may be particularly sensitive to hypoxia because their caudal lamellae (external gills) are frequently lost. In thisExpand
