Form, science, and narrative in the anthropocene [PDF]

open access: yes, 2019
A significant strand of contemporary fiction engages with scientific models that highlight a constitutive interdependency between humanity and material realities such as the climate or the geological history of our planet.

Patterning with clocks and genetic cascades: Segmentation and regionalization of vertebrate versus insect body plans.

open access: yesPLoS Genetics, 2021
Oscillatory and sequential processes have been implicated in the spatial patterning of many embryonic tissues. For example, molecular clocks delimit segmental boundaries in vertebrates and insects and mediate lateral root formation in plants, whereas ...

Octopus body language: body patterns of Abdopus capricornicus during social interactions.

open access: yesMarine Biology, 2023
Abstract Octopus are well known for their rapidly changing and diverse body patterning achieved through combinations of chromatic, textural and postural components. The function of octopus body patterns includes camouflage for prey ambush and predator avoidance, aposematic display to startle intruders and predators and potentially intraspecific

Sequential pattern formation governed by signaling gradients

open access: yes, 2016
Rhythmic and sequential segmentation of the embryonic body plan is a vital developmental patterning process in all vertebrate species. However, a theoretical framework capturing the emergence of dynamic patterns of gene expression from the interplay of ...

Cell polarity and patterning by PIN trafficking through early endosomal compartments in Arabidopsis thaliana [PDF]

open access: yes, 2013
PIN-FORMED (PIN) proteins localize asymmetrically at the plasma membrane and mediate intercellular polar transport of the plant hormone auxin that is crucial for a multitude of developmental processes in plants.

Callose homeostasis at plasmodesmata: molecular regulators and developmental relevance [PDF]

open access: yes, 2014
Plasmodesmata are membrane-lined channels that are located in the plant cell wall and that physically interconnect the cytoplasm and the endoplasmic reticulum (ER) of adjacent cells.

Patterns of Diversity in Soft-Bodied Meiofauna: Dispersal Ability and Body Size Matter [PDF]

open access: yesPLoS ONE, 2012
Biogeographical and macroecological principles are derived from patterns of distribution in large organisms, whereas microscopic ones have often been considered uninteresting, because of their supposed wide distribution. Here, after reporting the results of an intensive faunistic survey of marine microscopic animals (meiofauna) in Northern Sardinia, we

Spatial pattern formation in chemical and biological systems [PDF]

open access: yes, 1997
One of the central issues in developmental biology is the formation of spatial pattern in the embryo. A number of theories have been proposed to account for this phenomenon.

Drosophila Ge-1 promotes P body formation and oskar mRNA localization. [PDF]

open access: yesPLoS ONE, 2011
mRNA localization coupled with translational control is a widespread and conserved strategy that allows the localized production of proteins within eukaryotic cells.

The Origin And Loss Of Periodic Patterning In The Turtle Shell [PDF]

open access: yes, 2014
The origin of the turtle shell over 200 million years ago greatly modified the amniote body plan, and the morphological plasticity of the shell has promoted the adaptive radiation of turtles. The shell, comprising a dorsal carapace and a ventral plastron,
