Female insect pheromone blends induce robust tracking responses in males and direct them into traps. In vertebrates, pheromones that strong precise natural habitats have rarely been described. Here, we show the sea lamprey ( Petromyzon marinus ), a vertebrate invader of Laurential Great Lakes, synthesized component male mating pheromone, 7α, 12α, 24-trihydroxy-5α-cholan-3-one 24-sulfate (3kPZS), when released stream to reach concentrations 10 −14 , −13 −12 −11 or −10 M, triggers upstream...
Similar to many freshwater ecosystems, the Laurentian Great Lakes of North America have undergone numerous anthropogenic stressors resulting in considerable loss biodiversity and habitat. Among fishes, coregonine sub-family has endured most extensive declines, including extinction several species ( Coregonus johannae, C. alpenae, kiyi orientalis) at least 10 instances local extirpations other nigripinnis, reighardi, zenithicus, hoyi, artedi) across all 5 lakes, much which occurred prior...
A sulphate-conjugated bile alcohol, 3,12-diketo-4,6-petromyzonene-24-sulfate (DKPES), was identified using bioassay-guided fractionation from water conditioned with sexually mature male sea lamprey (Petromyzon marinus). The structure and relative stereochemistry of DKPES established spectroscopic data. electro-olfactogram (EOG) response threshold 10−7 Molar (M) that 3-keto petromyzonol sulfate (3 KPZS; a known component the sex pheromone) 10−10 M. Behavioural studies indicated can be...
Significance Anadromous fishes are those that migrate from the ocean into freshwater to reproduce and need orient toward a suitable spawning stream or risk leaving no offspring. These migrants known use olfactory cues guide selection, but cues’ identities not known. Incidentally, it is well-known stream-dwelling larval sea lampreys emit pheromone guides conspecific adults ascending streams. We identified this as fatty-acid derivative attracts migratory baited channel in natural stream....
Canada and the United States share Great Lakes and, for most of region's history, cross-border collaboration over fishery was nonexistent, resulting in serious economic ecological harm. This paper, which covers time span late 1800s to 1955, traces efforts during that period establish a binational treaty govern fishery. We explore circumstances fishers found themselves at dawn last century, chaos caused when multiple jurisdictions would not cooperate (called "divided governance" problem),...
Abstract Background In vertebrates, bile salts are primarily synthesized in the liver and secreted into intestine where they aid absorption of dietary fats. Small amounts that not reabsorbed enterohepatic circulation excreted with waste. sexually mature male sea lamprey ( Petromyzon marinus L.) a salt is released large across gill epithelia water it functions as pheromone. We postulate release this pheromone associated dramatic increase its biosynthesis transport to gills upon sexual...
Sea lampreys (Petromyzon marinus) invaded the Great Lakes in early twentieth century and caused considerable economic ecological harm. People who fished suffered crippling losses successfully lobbied elected officials Canada United States to create a sea lamprey control program which Fishery Commission implements under 1954 Convention on Fisheries. The relies two primary methods: chemical lampricides physical barriers. has been tremendous success; although urgency act is apparent certain...
We developed an assay for measuring 7α,12α,24-trihydroxy-5a-cholan-3-one-24-sulfate (3kPZS), a mating pheromone released by male sea lampreys (Petromyzon marinus), at low picomolar concentrations in natural waters to assess the presence of invasive populations. 3kPZS was extracted from streamwater rate recovery up 90% using single cation-exchange and reversed-phase mixed-mode cartridge, along with [(2)H(5)]3kPZS as internal standard, quantified ultrahigh performance liquid...
(+)- and (−)-Petromyroxol [(+)-1 (−)-1, respectively], two novel tetrahydrofuran (THF)-diol fatty acid enantiomers, were isolated from water conditioned with larval sea lamprey. We herein describe their isolation subsequent resolution using chiral chromatography. The absolute configuration of each enantiomer was determined by a combination Mosher ester analysis comparison related natural synthetic products. Electro-olfactogram (EOG) assays indicated that (+)-petromyroxol (1) possesses potent...
A new hexahydrophenanthrene sulfate was identified from water conditioned with sea lamprey larvae (Petromyzon marinus) and named petromyzonin. Its structure unequivocally elucidated on the basis of spectroscopic analyses including comparison spectra known compounds. The absolute configuration determined by electronic circular dichroism. Petromyzonin may function as a chemical signal, it elicited responses in electro-olfactogram recording dynamic concentration–response relationship detection...
Organisms continuously acquire and process information from surrounding cues. While some cues complement one another in delivering more reliable information, others may provide conflicting information. How organisms extract use a multitude of is largely unknown. We examined movement decisions sea lampreys (Petromyzon marinus L.) exposed to conspecific an environmental cue during pre-spawning migration. Specifically, we predicted that the mature male-released sex pheromone 3-keto petromyzonol...
Cisco ( Coregonus artedi Lesueur, 1818) in the Laurentian Great Lakes declined throughout 19th and 20th centuries. Managers are attempting to restore cisco other coregonines using multiple approaches, including stocking. A potential obstacle these efforts is that artificially reared can display deformities morphological differences compared wild fish, but impacts of artificial rearing on morphology not well understood. We morphologies their offspring, one family was exposed three temperature...
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,...
Lampreys (Petromyzontiformes) are a key component of freshwater ecosystems throughout temperate parts the world. Of 44 described species lamprey, sea lamprey (Petromyzon marinus) is certainly most commonly recognized. This has expanded its range from Atlantic Ocean basin where it conservation concern in North America and Europe into Laurentian Great Lakes subject to large-scale international control program. Many other imperiled require management intervention ensure their persistence. These...
Unique mixtures of pheromone components are commonly identified in insects, and have been shown to increase attractiveness towards conspecifics when reconstructed at the natural ratio released by signaler. In previous field studies pheromones that attract female sea lamprey (Petromyzon marinus, L.), putative male-released mating included newly described bile alcohol 3,12-diketo-4,6-petromyzonene-24-sulfate (DkPES) well characterized 3-keto petromyzonol sulfate (3kPZS). Here, we show chemical...
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...
SUMMARY Secondary sexual characters in animals are exaggerated ornaments or weapons for intrasexual competition. Unexpectedly, we found that a male secondary character sea lamprey (Petromyzon marinus) is thermogenic adipose tissue instantly increases its heat production during encounters. This character, developed front of the anterior dorsal fin mature males, swollen ridge known as ‘rope’ tissue. It contains nerve bundles, multivacuolar adipocytes and interstitial cells packed with small...
Two novel sulfated bile salt-like dienones, featuring either a unique, rearranged side chain or rare cis-11,12-diol on the steroidal C-ring, herein named petromyzene A (1) and B (2), respectively, were isolated from water conditioned with spawning male sea lamprey (Petromyzon marinus; jawless vertebrate animal). The structures of these natural products elucidated by mass spectrometry NMR spectroscopy. Petromyzenes exhibited high olfactory potency for adult strong behavioral attraction females.
Biliary atresia is a rare disease of infancy, with an estimated 1 in 15,000 frequency the southeast United States, but more common East Asian countries, reported 5,000 Taiwan. Although much known about management biliary atresia, its pathogenesis still elusive. The sea lamprey (Petromyzon marinus) provides unique opportunity to examine mechanism and progression degeneration. Sea develop through three distinct life stages: larval, parasitic, adult. During transition from larvae parasitic...
An enantiomeric pair of new fatty acid-derived hydroxylated tetrahydrofurans, here named iso-petromyroxols, were isolated from sea lamprey larvae-conditioned water. The relative configuration iso-petromyroxol was elucidated with 1D and 2D NMR spectroscopic analyses. ratio enantiomers (er) in the natural sample measured by chiral-HPLC-MS/MS to be ca. 3:1 (–)- (+)-antipodes.
