[Review of ]. FEBS JOURNAL, 282(21), 4080–4093.

By: G. LeBlanc n  & E. Medlock n

author keywords: doublesex; epigenetic; farnesoic acid O-methyltransferase; NMDA receptor; nutrition; parthenogenesis; photoperiod; sex lethal; temperature; transformer
MeSH headings : Animals; Daphnia / genetics; Daphnia / growth & development; Daphnia / physiology; Environment; Fatty Acids, Unsaturated / physiology; Female; Food; Male; Models, Biological; Neurosecretory Systems / physiology; Parthenogenesis / genetics; Parthenogenesis / physiology; Phenotype; Population Density; Seasons; Sex Determination Processes / genetics; Sex Determination Processes / physiology; Signal Transduction
TL;DR: This review describes the cascade of events beginning with environmental cues and ending with changes in gene expression that dictate male sex determination in daphnids, the initial event in the switch to sexual reproduction. (via Semantic Scholar)

A Transgenerational Endocrine Signaling Pathway in Crustacea

PLoS ONE, 8(4), e61715.

By: G. LeBlanc n , Y. Wang n, C. Holmes n, G. Kwon n & E. Medlock n

Ed(s): B. He

MeSH headings : Amino Acid Sequence; Animals; Cloning, Molecular; Crustacea / drug effects; Crustacea / metabolism; Daphnia / drug effects; Daphnia / physiology; Endocrine System / drug effects; Endocrine System / metabolism; Fatty Acids, Unsaturated / pharmacology; Female; Fertility; Genes, Reporter; Life Cycle Stages / drug effects; Ligands; Luciferases / metabolism; Male; Molecular Sequence Data; Population Density; Pyridines / pharmacology; Sex Determination Processes / drug effects; Sex Ratio; Signal Transduction / drug effects; Transcription Factors / chemistry
TL;DR: Results reveal likely components to a hormone/receptor signaling pathway in a crustacean that orchestrates transgenerational modifications to important population metrics (sex ratios, fecundity of females) and how these signaling processes can facilitate population sustainability under normal conditions or threaten sustainability when perturbed by environmental chemicals.
