WNK1 regulates uterine homeostasis and its ability to support pregnancy
JCI Insight, 2020 WNK1 (with no lysine [K] kinase 1) is an atypical kinase protein ubiquitously expressed in humans and mice. A mutation in its encoding gene causes hypertension in humans, which is associated with abnormal ion homeostasis.

A single-cell atlas of the myometrium in human parturition
JCI Insight, 2022 Parturition is a well-orchestrated process characterized by increased uterine contractility, cervical ripening, and activation of the chorioamniotic membranes; yet, the transition from a quiescent to a contractile myometrium heralds the onset of labor ...

Notes on the Reproductive Biology of the Alabama Red Hills Salamander (Phaeognathus hubrichti ) [PDF]
, 2003 Living Amphibia exhibit two major life history modes, possession of an aquatic larval stage or direct development, with the latter assumed to be the derived evolutionary condition (Duellman and Trueb 1986, Wake 1989).

Implications of fisheries during the spawning season for the sustainable management and recovery of depleted fish stocks: a conceptual framework [PDF]
, 2009 Fishing during the spawning season may negatively affects the reproductive potential and reproductive dynamics of exploited fish stocks due to a variety of mechanisms such as the disturbance of the natural spawning behaviour, effects on the age, size and
