A CTCF-dependent mechanism underlies the Hox timer relation to a segmented body plan

During gastrulation, Hox genes are activated in a timesequence that follows the order of the genes along their clusters. This property, which is observed in all animals that develop following a progressive rostral-to-caudal morphogenesis, is associated wit ...

Gene expression of Pocillopora damicornis coral larvae in response to acidification and ocean warming

Nils Rädecker, Hui Huang

Objectives The endosymbiosis with Symbiodiniaceae is key to the ecological success of reef-building corals. However, climate change is threatening to destabilize this symbiosis on a global scale. Most studies looking into the response of corals to heat str ...

Home, with what remains: A sorting-house as a form of occupancy right

Hervé Laurendeau

North of La Rochelle, the Baie de l'Aiguillon bears witness to a structurally invasive past, partially camouflaged in its shallow waters. 400 hectares of abandoned oyster beds locally known as crassats, remnants of the shellfish industry, lie in the intert ...

Hunting for the wavefront: investigation of somite boundary positioning in zebrafish

Arianne Bercowsky Rama

Somitogenesis is the rhythmic and sequential formation of somites, which are tissue blocks that give rise to segmented adult body structures including the vertebrae and associated muscle. Somite formation is controlled by the segmentation clock, a populati ...

High light quantity suppresses locomotion in symbiotic Aiptasia

Anders Meibom, Nils Rädecker, Claudia Isabella Pogoreutz

Many cnidarians engage in endosymbioses with microalgae of the family Symbiodiniaceae. In this association, the fitness of the cnidarian host is closely linked to the photosynthetic performance of its microalgal symbionts. Phototaxis may enable semi-sessil ...

Inter-embryo gene expression variability recapitulates the hourglass pattern of evo-devo

Bart Deplancke, Vincent Roland Julien Gardeux, Michael Vincent Frochaux

Background The evolution of embryological development has long been characterized by deep conservation. In animal development, the phylotypic stage in mid-embryogenesis is more conserved than either early or late stages among species within the same phylum ...

Assessment of abundance and community composition of benthic macroinvertebrates: recommendations for improved sampling, fixation and extraction of oligochaetes

Benoît Jean Dominique Ferrari, Régis Lionel Vivien

For several decades, the abundance and community structure of benthic macroinvertebrates have been studied to assess the biological quality of aquatic ecosystems. Procedures aiming at studying the whole of macroinvertebrate communities were mainly designed ...

On the Evaluation and Real-World Usage Scenarios of Deep Vessel Segmentation for Funduscopy

André Anjos

We identify and address three research gaps in the field of vessel segmentation for funduscopy. The first focuses on the task of inference on high-resolution fundus images for which only a limited set of ground-truth data is publicly available. Notably, we ...

Diet modulates cecum bacterial diversity and physiological phenotypes across the BXD mouse genetic reference population

Johan Auwerx, Evan Graehl Williams

The BXD family has become one of the preeminent genetic reference populations to understand the genetic and environmental control of phenotypic variation. Here we evaluate the responses to different levels of fat in the diet using both chow diet (CD, 13-18 ...

Life-history trade-offs and limitations associated with phenotypic adaptation under future ocean warming and elevated salinity

Emma Mary Gibbin, Félix Christen

Little is known about the life-history trade-offs and limitations, and the physiological mechanisms that are associated with phenotypic adaptation to future ocean conditions. To address this knowledge gap, we investigated the within-and trans-generation li ...
