Post-embryonic nerve-associated precursors to adult pigment cells: genetic requirements and dynamics of morphogenesis and differentiation.

open access: yesPLoS Genetics, 2011
The pigment cells of vertebrates serve a variety of functions and generate a stunning variety of patterns. These cells are also implicated in human pathologies including melanoma.

Evolution of danio pigment pattern development [PDF]

open access: yesHeredity, 2006
Pigment patterns of danio fishes are emerging as a useful system for studying the evolution of developmental mechanisms underlying adult form. Different closely related species within the genera Danio and Devario exhibit a range of pigment patterns including horizontal stripes, vertical bars, and others.

The Stiles-Crawford Effect in the Eye of the Blowfly, Calliphora erythrocephala [PDF]

open access: yes, 1985
Stiles-Crawford-like effects (that is, directional sensitivity of the retina) were investigated in the fly’s eye. Intracellular recordings from the visual sense cells were made, and the radiation patterns emerging from the photoreceptors with antidromic ...

Developmental and Cellular Basis of Vertical Bar Color Patterns in the East African Cichlid Fish Haplochromis latifasciatus

open access: yesFrontiers in Cell and Developmental Biology, 2020
The East African adaptive radiations of cichlid fishes are renowned for their diversity in coloration. Yet, the developmental basis of pigment pattern formation remains largely unknown.

Toward identification of larval sailfish (Istiophorus platypterus), white marlin (Tetrapturus albidus), and blue marlin (Makaira nigricans) in the western North Atlantic Ocean* [PDF]

open access: yes, 2005
The identification of larval istiophorid billfishes from the western North Atlantic Ocean has long been problematic. In the present study, a molecular technique was used to positively identify 27 larval white marlin (Tetrapturus albidus), 96 larval blue ...

Dedicated Epithelial Recipient Cells Determine Pigmentation Patterns [PDF]

open access: yesCell, 2007
Mammals generate external coloration via dedicated pigment-producing cells but arrange pigment into patterns through mechanisms largely unknown. Here, using mice as models, we show that patterns ultimately emanate from dedicated pigment-receiving cells. These pigment recipients are epithelial cells that recruit melanocytes to their position in the skin

Development of kelp rockfish, Sebastes atrovirens (Jordan and Gilbert 1880), and brown rockfish, S. auriculatus (Girard 1854), from birth to pelagic juvenile stage, with notes on early larval development of black-and-yellow rockfish, S. chrysomelas (Jordan and Gilbert 1880), reared in the laboratory (Pisces: Sebastidae). [PDF]

open access: yes, 2004
Larval kelp (Sebastes atrovirens), brown (S. auriculatus), and blackand-yellow (S. chrysomelas) rockfish were reared from known adults, to preflexion stage, nine days after birth for S. chrysomelas, to late postflexion stage for S.
