A diploblastic radiate animal at the dawn of cambrian diversification with a simple body plan: distinct from Cnidaria? [PDF]
PLoS ONE, 2013 Microfossils of the genus Punctatus include developmental stages such as blastula, gastrula, and hatchlings, and represent the most complete developmental sequence of animals available from the earliest Cambrian.

Maternal and Embryonic Stress Influence Offspring Behavior in the Cuttlefish Sepia officinalis
Frontiers in Physiology, 2017 Stress experienced during prenatal development—either applied to reproducing females (maternal stress), directly to developing offspring (embryonic stress) or in combination—is associated with a range of post-natal behavioral effects in numerous ...

Coordination of limb bud development : the role of SHH in PD limb bud patterning [PDF]
, 2012 The limb bud serves as an excellent model to investigate the signals involved in diverse processes during embryonic development. Limb bud development is controlled by complex regulatory networks that instruct coordinated patterning and proliferation of ...

ERK1/2 is an ancestral organising signal in spiral cleavage
Nature Communications, 2022 How invertebrates with spiral cleavage establish their body plans is unclear. Here the authors show that, like molluscs, a basal annelid uses ERK1/2 to instruct body patterning, suggesting that this is a deep ancestral trait in animal embryogenesis.

Frontiers in Cell and Developmental Biology, 2022 Specification and elaboration of proximo-distal (P-D) axes for structures or tissues within a body occurs secondarily from that of the main axes of the body. Our understanding of the mechanism(s) that pattern P-D axes is limited to a few examples such as

Frontiers in Physiology, 2021 The speed of adaptive body patterning in coleoid cephalopods is unmatched in the natural world. While the literature frequently reports their remarkable ability to change coloration significantly faster than other species, there is limited research on ...

Anterior-posterior gene expression differences in three Lake Malawi cichlid fishes with variation in body stripe orientation [PDF]
PeerJ, 2017 Morphological differentiation among closely related species provides opportunities to study mechanisms shaping natural phenotypic variation. Here, we address variation in the orientation of melanin-colored body stripes in three cichlid species of the ...

Prediction of total body water in infants and children [PDF]
, 2005 Background: In paediatric clinical practice treatment is often adjusted in relation to body size, for example the calculation of pharmacological and dialysis dosages. In addition to use of body weight, for some purposes total body water (TBW) and surface
