The sea lamprey, Petromyzon marinus, is a destructive invader in the Laurentian Great Lakes that relies on several complex chemical cues to complete their life cycle. central roles of lamprey reproduction provide opportunities leverage knowledge ecology when developing alternative or supplemental strategies for control. A solid foundation has been laid regarding ecology, with recent advances our understanding migratory pheromone, male sex and alarm broadening fundamental diversity,...
ABSTRACT Migratory fishes are renowned for their ability to home natal streams spawning. Learned olfactory cues play a critical role in homing of Pacific salmon and other fishes, but the underlying chemical signature remains poorly understood after decades study. The molecules that convey stream‐specific odour must differ among sites remain constant over time. Among leading odorant candidates amino acids; however, little research has assessed spatial temporal variability acid profiles...
The role of the C24 sulphate in mating pheromone component, 7α,12α,24-trihydroxy-5α-cholan-3-one 24-sulphate (3kPZS), to specifically induce upstream movement ovulated female sea lampreys Petromyzon marinus was investigated. 7α,12α-dihydroxy-5α-cholan-3-one 24-oic acid (3kACA), a structurally similar bile released by spermiated males, but lacking ester, tested bioassays at concentrations between 10(-11) and 10(-14) molar (M). 3kACA did not females or additional reproductive behaviours. In...
Receiver bias models suggest that a male sexual signal became exaggerated to match pre-existing sensory, perceptual or cognitive disposition of the female. Accordingly, these predict females related taxa possessing ancestral state signalling evolved preference for trait in non-sexual context. We postulated female male-released bile alcohol mating pheromone, 3 keto petromyzonol sulfate (3kPZS), sea lamprey (Petromyzon marinus) as result receiver bias. In particular, we propose migratory...
The sensory trap model of signal evolution suggests that males manipulate females into mating using traits mimic cues used in a nonsexual context. Despite much empirical support for traps, little is known about how evolve response to these deceptive signals. Female sea lamprey (
The pouched lamprey (Geotria australis), one of four Southern Hemisphere species, is New Zealand’s only freshwater representative the agnathans. In contrast to that Northern lampreys, reproductive ecology lampreys poorly understood, with no documented nesting sites or spawning behaviours. present study, we utilized passive integrated transponder tags track migratory adult G. australis locate sites. Across 2 years, six cryptic were discovered, each containing eggs and a single male female...
The sensory trap model of signal evolution hypothesizes that signalers adapt to exploit a cue used by the receiver in another context. Although exploitation biases can result conflict between sexes, deceptive signaling systems are mutually beneficial drive stable communication systems. However, female responses nonsexual and sexual contexts may become uncoupled if costs associated with exhibiting similar response trait both contexts. Male sea lamprey ( Petromyzon marinus ) mating pheromone,...
Animals rely on a mosaic of complex information to find and evaluate mates. Pheromones, often consisting multiple components, are considered be particularly important for species-recognition in many species. Although the evolution species-specific pheromone blends is well described insects, very few vertebrate pheromones have been studied macro-evolutionary context. Here, we report phylogenetic comparison multi-component male odours that guide reproduction lampreys. Chemical profiling...
Two sounds associated with spawning lake trout (Salvelinus namaycush) in lakes Huron and Champlain were characterized by comparing sound recordings behavioral data collected using acoustic telemetry video. These named “growls” “snaps” heard on reefs, but not a nonspawning reef, more common at night than during the day. Growls also occurred often period prespawning period, while trend for snaps was reversed. In laboratory flume, when male displaying behaviors: growls males quivering parallel...
Significance In many animals, males deceive females into mating using traits that mimic cues of food, predators, preferred habitats, or offspring in need care. However, if and how these deceptive signals guide reliable communication without confusing the model remain unclear. We discovered female sea lamprey discriminate a nonsexual cue productive habitat from male sex pheromone mimics it identify antagonist as underlying mechanism. Our results implicate means by which can detect benefit...
Abstract Many migratory fishes are thought to navigate natal streams using olfactory cues learned during early life stages. However, direct evidence for early-life imprinting is largely limited Pacific salmon, and other species suspected imprint show history traits reproductive strategies that raise uncertainty about the generality of salmonid-based conceptual model in fishes. Here, we studied lake sturgeon (Acipenser fulvescens), which have a cycle notably different from but nonetheless...
Pheromones are important sexual signals in most animals, but research into their evolution is largely biased toward insects. Lampreys a jawless fish with relatively well-understood pheromone communication system, and they offer useful opportunity to study vertebrate. Once sexually mature, male sea lamprey (Petromyzon marinus) likely other lampreys produce release bile acids that act as sex pheromones. Spawning males do not feed therefore primarily for communication, whereas larvae the same...
