Abstract Phenotypic plasticity, such as morphological and behavioral changes in response to predators, is common in larval anurans. Less is known about inducible defenses in the embryonic stages of development. We investigated the predation risk imposed by crayfish (Procambarus nigrocinctus) on southern leopard frog (Rana sphenocephala) eggs and whether crayfish presence induces a change in the timing of hatching of R. sphenocephala eggs. We found that crayfish significantly reduce the hatching… 

Flatworms (Schmidtea nova) prey upon embryos of the common frog (Rana temporaria) and induce minor developmental acceleration

The detected trend suggests that direct and indirect cues from flatworms, rarely considered as anuran predators, might induce a developmental response in R. temporariaearly developmental stages.

HATCHING PLASTICITY OF WOOD FROG ( RANA SYLVATICA ) EGGS IN RESPONSE TO MOSQUITOFISH ( GAMBUSIA AFFINIS ) CUES

It is suggested that Wood Frogs can accelerate hatching in the presence of cues from Mosquitofish, andEmbryos in no barrier treatments hatched significantly faster than embryos in the barrier treatments, which hatched significantly earlier than babies in the control treatments.

To hatch and hatch not: similar selective trade-offs but different responses to egg predators in two closely related, syntopic treefrogs

It is found that A. spurrelli embryos showed a stronger hatching response to submergence underwater than to snake attacks even though submergence is a less frequent risk, which suggests they have a greater capacity for early hatching than is expressed in the context of snake attacks, but have much lower sensitivity to snake cues than to flooding cues.

08. Non-consumptive effects of predatory three-spined sticklebacks ( Gasterosteus aculeatus ) on great crested newt ( Triturus cristatus ) embryos

The results suggest the potential for negative non-consumptive impacts of predatory sticklebacks on great crested newts during the embryonic stage and suggest the presence of predators during embryonic development may elicit adaptive responses in emerging larvae.

Hatching plasticity in two temperate anurans: responses to a pathogen and predation cues

Testing the ability of two species of North American anurans with different breeding phenologies to alter their hatching timing in response to three indicators of environmental risk found that hatching occurs through enzymatic egg capsule degradation combined with ciliary movement, not through behavior.

Avoiding Predation: The Importance of Chemical and Visual Cues in Poison Frog Reproductive Behaviour

It is suggested that the invertebrate predators mask their chemical cues, forcing the frogs to use other senses to detect them, and that the parent frogs avoid conspecific ­cannibalistic tadpoles and damselfly larvae of the species Microstigma rotundatum.

Developmental windows and origins of the chemical cues mediating hatching responses to injured conspecific eggs in the common frog (Rana temporaria)

Common frog eggs exposed at Gosner stage 2, 16, or 20 to chemical cues simulating predation on whole eggs, jelly envelopes, or embryos appeared unaffected by the nature of the treatment, but the embryonic treatments strongly affected the morphology of hatchlings.

Hatching responses of four newt species to predatory fish chemical cues

Exposure to predator cues did not affect the timing of hatching, but led to an earlier development stage at hatching and smaller hatchling size, which might represent non-adaptive developmental costs associated with the presence of predators.

Female guppies shorten brood retention in response to predator cues

It is suggested that the conditions experienced by gestating females can generate significant variation in the timing of offspring development with potentially important implications for offspring fitness.

Effects of ontogenetic stage and density on the ecological role of the signal crayfish (Pacifastacus leniusculus) in a coastal Pacific stream

The composition of the cobble-bottom invertebrate community was not significantly affected by the presence of crayfish, regardless of density or ontogenetic stage, and the leaf-pack invertebrates community composition and abundance were negatively affected by cray fish presence, but these results were independent ofcrayfish ontogenetics stage and total biomass.

Predator‐induced life history changes in amphibians: egg predation induces hatching

It is documented that both treefrogs and Cascades frogs show plasticity in hatching characteristics in response to the threat of egg predation, which may reduce predation in populations that experience high variability in predation pressure between years.

Delayed hatching as a response of streamside salamander eggs to chemical cues from predatory sunfish

The effects of chemical cues from green sunfish on the timing of hatching for streamside salamander eggs were examined and it was predicted that eggs should delay hatching in response to the presence of sunfish.

Delayed Hatching of Salamander Eggs in Response to Enhanced Larval Predation Risk

This article presents the first test of the hypothesis that variation in size-dependent predation risk on hatchings can cause adaptive shifts in the timing of egg hatching and thus on the size and developmental stage of new hatchlings, and indicates flatworms and flatworm chemicals induced eggs to delay their hatching to a later time and thus a larger size and more advanced developmental stage.

Pond tadpoles with generalized morphology: is it time to reconsider their functional roles in aquatic communities?

It is suggested that predation risk is greater in temporary ponds than in more permanent ponds for many organisms that are vulnerable to predation by tadpoles, and a conditional model based upon interactions that are species- specific, life-stage-specific, and context-dependent may better explain community organization along hydrological gradients than models which assume that temporary ponds have few or no predators.

The advertisement call of Rana arathooni is unusually complex and invariant and call structure is unique in that amplitude and frequency are inversely correlated.

Early hatching as an antipredator defence of red-eyed treefrog embryos, Agalychnis callidryas, in response to egg predation by social wasps is studied, finding plasticity in hatching stage allows embryos to balance risks from stage-specific egg and larval predators.

Specific induced responses to different predator species in anuran larvae

The evolutionary maintenance of specialized responses to multiple predators may be possible because adaptive responses do not conflict and the predators themselves do not interact strongly, which would facilitate evolution of adaptive behavioural responses.

Predator-induced morphological changes in an amphibian: predation by dragonflies affects tadpole shape and color

By exposing tadpoles to tail damage and the non-lethal presence of starved and fed dragonflies, it is determined that these phenotypic differences are induced by non-contact cues present when dragonflies prey on Hyla.

EGG‐KILLING FUNGUS INDUCES EARLY HATCHING OF RED‐EYED TREEFROG EGGS

It is indicated that pathogens can influence the timing of life history transitions, as do other stage-specific risks, and embryos hatched earlier from both naturally infected and inoculated clutches than from fungus-free control clutches.
