Towards deciphering variations of heart regeneration in fish

Jaźwińska, Anna ; Blanchoud, Simon

In: Current Opinion in Physiology, 2020, vol. 14, p. 21–26

Among adult vertebrates, the zebrafish presents the rather exceptional capacity to efficiently regenerate its heart after injury. This bony fish has thus become a leading genetic model organism to elucidate the natural mechanisms of successful cardiac restoration. Given its potential biomedical significance, parallel analyses between zebrafish and mammals are aiming at the identification of...

Ecological constraints coupled with deep-time habitat dynamics predict the latitudinal diversity gradient in reef fishes

Gaboriau, Théo ; Albouy, Camille ; Descombes, Patrice ; Mouillot, David ; Pellissier, Loïc ; Leprieur, Fabien

In: Proceedings of the Royal Society B: Biological Sciences, 2019, vol. 286, no. 1911, p. 20191506

We develop a spatially explicit model of diversification based on palaeohabitat to explore the predictions of four major hypotheses potentially explaining the latitudinal diversity gradient (LDG), namely, the ‘time-area’, ‘tropical niche conservatism’, ‘ecological limits’ and ‘evolutionary speed’ hypotheses. We compare simulation outputs to observed diversity gradients in the...

Upper Domination : Towards a Dichotomy Through Boundary Properties

AbouEisha, Hassan ; Shahid, Hussain ; Lozin, Vadim ; Monnot, Jérôme ; Ries, Bernard ; Zamaraev, Viktor

In: Algorithmica, 2018, vol. 80, no. 10, p. 2799-2817

Anupper dominating set in a graph is a minimal dominating set of maximum cardinality. The problem of finding an upper dominating set is generally NP-hard.We study the complexity of this problem in finitely defined classes of graphs and conjecture that the problem admits a complexity dichotomy in this family. A helpful tool to study the complexity of an algorithmic problem is the notion of...

Enhancing scientific communication skills: a real-world simulation in a tertiary-level life science class using e-learning technology in biomedical literature perception, reflective review writing on a clinical issue, and self and peer assessments

Eppler, Elisabeth ; Meyer, Jan ; Serowy, Steffen ; Link, Karl ; Pauk, Barbara ; Filgueira, Luis

In: Research in Science Education, 2018, p. -

This educational study aimed to explore the feasibility and acceptance of a literacy exercise adopted from the realworld of scientific publishing in a cell and tissue biology course. For that purpose, a tertiary-level multimodality science course, which integrated a blended learning faculty and student lectures, journal club, and wet laboratory sessions including a research project as well as...
