Female fish in the Bahamas have developed ways of showing males that "No means no."
As snowpack levels decline with the warming climate, many streams will experience less water flow, especially during summer months, potentially exposing more fish to predation by birds and other animals.
Pond snails are able to sense chemicals released by their predators whilst they are still embryos in the egg and alter their behaviour accordingly, according to new research.
Fishing vessels have a far bigger ecological footprint than previously thought, according to research which tracked the movement and behaviour of seabirds using GPS devices.
(Phys.org) —Fish waste left on beaches by recreational fishers could harm shore-nesting birds by attracting native crows that eat the birds' eggs, a UNSW-led study shows.
Florida won't be repeating a public hunt meant to reduce the population of invasive Burmese pythons in the Everglades.
Research published in the Royal Society Journal, Interface, has demonstrated that predatory fish sneak up on lightning-fast prey by disguising water disturbances as they approach.
(Phys.org) —"Blend in" appears to be the mantra for male Bahamas mosquitofish that live near predators. After all, fish with brighter, more colorful fins or patches are more conspicuous – and standing out with predators ...
(Phys.org) —When predators lurk nearby, male Bahamas mosquitofish (Gambusia hubbsi) change mating strategies, rejecting elaborate courting rituals for more frequent and sometimes forceful encounters with females.
The weakly electric fish, so named because it generates a weak electric field, can do some very cool things. Using sensors located all over its body, for example, it can detect prey or predators that interrupt its surrounding ...
