Many animals heavily invest in parental care but still reject at least some of their offspring. Although seemingly paradoxical, selection can favor parents to neglect offspring of particularly low reproductive value, for example, because of small sur

We provide histological details of the development of oocytes in the cyprinodontid flagfish, Jordanella floridae. There are six stages of oogenesis: Oogonial proliferation, chromatin nucleolus, primary growth (previtellogenesis [PG]), secondary growt

Understanding the environmental risks of pharmaceuticals and personal care products (PPCPs) has become very important in the field of aquatic toxicology. Hydroxylpropyl-β-cyclodextrin (HPβCD) is an amphiphilic, toroidal shaped molecule with the abi

In an 8-month mesocosm experiment, we examined how a simulated Everglades aquatic community of small native fishes, snails, and shrimp changed with the addition of either a native predator (dollar sunfish Lepomis marginatus) or a non-native predator

We hypothesized that fishes in short-hydroperiod wetlands display pulses in activity tied to seasonal flooding and drying, with relatively low activity during intervening periods. To evaluate this hypothesis, sampling devices that funnel fish into tr

This study evaluated the effects of Chilean pulp mill effluent extracts (untreated, primary and secondary treated pulp mill effluents), along with steroid standards (testosterone and 17β-estradiol) and a wood extractive standard (beta-sitosterol) on

Operational sex ratio (OSR, the ratio of sexually active males to fertilizable females at a given time and location) affected male behaviour in the flagfish Jordanella floridae. When OSR was male biased, males spent (1) more time at their nests and (

Parents should adjust parental care if the costs and benefits of that care vary. Traditionally, the benefit of care has been assumed to be increased offspring fitness, yet increasing evidence indicates that care can also increase mating success. We e
