Friends in Low Places: Responses of a Benthic Stream Fish to Intra-Guild Alarm Cues
<p>Many aquatic species produce chemical alarm cues that serve as a warning to nearby conspecifics. In mixed-species aggregations, individuals may also benefit by “eavesdropping” on the chemical alarm cues of other species that are in the same prey-guild. Rainbow Darters (Etheostoma caeruleum) are …

The Influence of Tail Autotomy on Avoidance of Chemical Alarm Cues in Northern Zigzag Salamanders, Plethodon dorsalis
… predator avoidance. Salamanders detect chemical alarm cues via the vomeronasal organ and their avoidance of the chemical cues is based upon the apparent associated risk. The objective of this study was to better understand predator avoidance by means of chemical alarm cues in northern zigzag …

Behavioral and Metabolic Responses of Juvenile Spotted Salamanders (Ambystoma Maculatum) to Alarm Cues from Damaged Skin and Predator Diet
… maculatum, to assess predation risk via chemical alarm cues and substrate markings from predators fed different diets. In the alarm-cue experiment, salamanders avoided substrates marked with alarm cues but not from noninjured conspecifics or alarm stimuli from heterospecifics. Snakes that had …

The role of embryonic risk cues on the life history, morphology and behaviour of the wood frog Lithobates sylvaticus
… their environment. Chemical information, such as alarm cues and disturbance cues, are known to play an important role in risk assessment for aquatic species and stimulates phenotypic plasticity. Alarm cues are chemicals released by a prey that have been attacked by a predator, while disturbance …

EARLY-LIFE DEVELOPMENT OF ANTIPREDATOR BEHAVIOUR OF JUVENILE NORTHERN CRAYFISH (FAXONIUS VIRILIS)
… environments, prey frequently rely on chemical cues, such as conspecific alarm cues, to assess predation risk and guide antipredator responses. Early exposure to risk-related cues can influence the development of antipredator strategies, including generalized responses to novelty (neophobia) and …

Predator Recognition Learning in Rainbow Darters (Etheostoma Caeruleum)
… (Etheostoma caeruleum) could learn to associate cues from an unfamiliar predator with a known fright stimulus (darter alarm cues) through the process of classical conditioning. Darters in the experimental group (n=32) were trained using their alarm cues paired with cues from larval ringed …

The impact of carbon dioxide on freshwater fish behaviors
… following exposure to conspecific skin extracts (alarm cues). In fathead minnows, their response to conspecific skin extracts were significantly impaired following exposure to elevated CO2 levels for at least 96 h, while silver carp behaviors were unaltered. However, fathead minnow behaviors did …

Predator recognition and anti-predator behavior in juvenile Asian carp
… fishes. Chemical, social, and similar predator cues may all inform an individual of a possible impending predatory threat. Bighead (Hypophthalmichthys nobilis) and silver carp (H. molitrix) widespread invasive fishes, and can be vulnerable to predation during their first year. Because they now …

An Investigation of the Effect of Malathion on Adaptive Plasticity of Pseudacris sierra
… biotic and abiotic factors. Tadpoles detect alarm cues released from tadpoles being eaten and kairomones that are released by predators. Tadpoles respond to these signals by changing tail and body shape along with a reduction of activity level, which enables tadpoles to escape predators more …
