Vitellogenin in the European cave salamander, Proteus anguinus: Its characterization and dynamics in a captive female as a basis for non-destructive sex identification

Differential proteomics between unhatched male and female egg yolks reveal the molecular mechanisms of sex-allocation and sex-determination in chicken

“…Loligo -microseminoproteins were synthesized in female reproductive exocrine glands and embed protein in the outer tunic of egg capsules, which were regarded as pheromone to attract male fighting with nearby males ( Cummins et al, 2011 ). Vitellogenin (precursor protein of egg yolk) has been reported as a promising molecular marker (female-specific protein) for sex identification in P. anguinus and geoducks ( Kim et al, 2018 ; Gredar et al, 2019 ).…”

Behavioral observations of the olm (Proteus anguinus) in a karst spring via direct observations and camera trapping

“…Further, the application of environmental DNA approaches facilitated the detection of olm presence and supplemented its previously known geographical distribution (Gorički et al 2017;Vörös et al 2017). Significant progress in olm's developmental biology, essential for sustainable captive breeding has been made in the last years (Gredar et al 2019), and even sanctuaries for injured animals and individuals washed-out from their subterranean habitat were established (Aljančič et al 2014;Lewarne 2018). Finally, deciphering the olm's genome is underway, promising great potential for further progress in olm conservation (Kostanjšek et al 2022).…”
