Yellow-bellied marmots discriminate between the alarm calls of individuals and are more responsive to calls from juveniles
Unlike individually distinctive territorial calls, contact calls, or calls that aid in the recognition of young by their parents, the function or functions of individually distinctive alarm calls (vocalizations produced in response to predators) is not immediately apparent. Yellow-bellied marmots, Marmota flaviventris, grounddwelling sciurid rodents, produce individually distinctive alarm calls...
متن کاملChemical Alarm Cues Are Conserved within the Coral Reef Fish Family Pomacentridae
Fishes are known to use chemical alarm cues from both conspecifics and heterospecifics to assess local predation risks and enhance predator detection. Yet it is unknown how recognition of heterospecific cues arises for coral reef fishes. Here, we test if naïve juvenile fish have an innate recognition of heterospecific alarm cues. We also examine if there is a relationship between the intensity ...
متن کاملSensitivity of northern redbelly dace, Phoxinus eos, to chemical alarm cues
The northern redbelly dace, Phoxinus eos (Cope, 1862), is subject to predation by brook trout, Salvelinus fontinalis (Mitchill, 1814), in Canadian Shield lakes, particularly when individuals migrate to the pelagic zone at sunset to feed on zooplankton and fish shoals break up into single individuals. The objectives of the present study were to (i) determine whether northern redbelly dace react ...
متن کاملGrowth-altering microbial interactions are responsive to chemical context
Microbial interactions are ubiquitous in nature, and are equally as relevant to human wellbeing as the identities of the interacting microbes. However, microbial interactions are difficult to measure and characterize. Furthermore, there is growing evidence that they are not fixed, but dependent on environmental context. We present a novel workflow for inferring microbial interactions that integ...
