Defense in the aeolidoidean genus phyllodesmium (gastropoda).
We report results of the first chemical investigation of P. briareum, as well as a re-investigation of P. longicirrum and P. magnum. Briarane diterpenes were isolated from P. briareum, and their origin could be traced to its prey organism Briareum sp. (Octocorallia). Considerable enrichment of the s...
Ambient has Become Strained. Identification of Acacia dealbata Link Volatiles Interfering with Germination and Early Growth of Native Specie...
We hypothesized that volatile organic compounds (VOCs) released from flowers, leaves, litter, or a mixture of treatments exert inhibitory effects on the natives Trifolium subterraneum, Lolium multiflorum, Medicago sativa, and also on its own seeds. We reported that VOCs from flowers significantly re...
The effect of caste and reproductive state on the chemistry of the cephalic labial glands secretion of Bombus terrestris.
We present chemical analyses of their secretion in queens and workers of Bombus terrestris under various social conditions. The secretion revealed a context-dependent composition with sterile females possessing large amounts of fatty acid dodecyl esters, ranging from dodecyl hexanoate to dodecyl ole...
Proteomic analyses of courtship pheromones in the redback salamander, Plethodon cinereus.
The evolutionary success of plethodontid salamanders for ~100 MY is due partly to the use of courtship pheromones that regulate female receptivity. In ~90 % of plethodontid species, males deliver pheromones by "scratching" a female's dorsum, where pheromones diffuse transdermally into the bloodstrea...
The evolution of ethylene signaling in plant chemical ecology.
We provide a synthesis of the role of ethylene in the context of plant ecology and evolution, and a prospectus for future research in this area. We focus on the regulatory function of ethylene in multi-organismal interactions. In general, plant interactions with different types of organisms lead to...
Symptomless endophytic fungi suppress endogenous levels of salicylic acid and interact with the jasmonate-dependent indirect defense traits ...
We used wild Lima bean (Phaseolus lunatus) plants that were experimentally colonized with one of three strains of natural endophytes (Bartalinia pondoensis, Fusarium sp., or Cochliobolus lunatus) to investigate the effects of fungal colonization on the endogenous levels of salicylic acid (SA) and ja...
Identification and biosynthesis of novel male specific esters in the wings of the tropical butterfly, Bicyclus martius sanaos.
We report the identification and biosynthetic pathways of several novel esters from the wings of male B. martius sanaos. We found that the volatile compounds in this male butterfly were similar to female-produced moth sex pheromones. Components associated with the male wing androconial areas were id...
The inverted phantom giant.
Nectar minerals as regulators of flower visitation in stingless bees and nectar hoarding wasps.
Various nectar components have a repellent effect on flower visitors, and their adaptive advantages for the plant are not well understood. Persea americana (avocado) is an example of a plant that secretes nectar with repellent components. It was demonstrated that the mineral constituents of this nec...
Involvement of a specific chemosensory protein from Bactrocera dorsalis in perceiving host plant volatiles.
Insects have evolved many physiological and behavioral adaptations to recognize external complex chemicals. Olfaction plays an important role in perceiving volatile chemicals, utilizing them to locate host sites, conspecifics, and enemies. Chemosensory proteins (CSPs) are present in high concentrati...
