The edible sea urchin Loxechinus albus (Molina, 1782) is a keystone species in the littoral benthic systems of the Pacific coast of South America. The international demand for high-quality gonads of this echinoderm has led to an extensive exploitation and decline of its natural populations. Consequently, a more thorough understanding of L. albus gonad development and gametogenesis could provide...
Robustness to mutations is a general principle of biological systems that allows for the accumulation of cryptic variation. However, little is known about robustness and cryptic variation in core developmental pathways. Here we show through gonad-ablation screens in natural isolates of Pristionchus pacificus cryptic variation in nematode vulva development. This variation is mainly caused by cis...
BACKGROUND In humans, the adrenal glands and gonads undergo distinct biological events between 6-10 weeks post conception (wpc), such as testis determination, the onset of steroidogenesis and primordial germ cell development. However, relatively little is currently known about the genetic mechanisms underlying these processes. We therefore aimed to generate a detailed genomic atlas of adrenal a...

Introduction Black (H. cracherodii) and white abalone sorenseni) are federally listed as endangered species in the United States. Conservation efforts include captive breeding programs; however, determination of reproductive state individual is notoriously difficult using traditional visual assessments. Ultrasonography a well-recognized technology used to assess gonad condition accurately nonle...
