Density‐driven bottlenecks constrain restoration of macroalgal forests

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
This single‐species and single‐site experiment provides evidence that high‐density restoration strategies accelerate mortality, suppress growth and delay reproduction, whereas low‐density approaches promote faster demographic progression and resilience. Under the conditions tested here, focusing on growth and reproductive output, rather than maximising

Obtaining accurate radial velocities for Cepheid companions using the STIS echelles

EPJ Web of Conferences, 2017
We discuss the high dispersion echelle observations of the hot binary companions of six Cepheids with known radial-velocity orbits that we have obtained with the STIS FUV E140H mode on board the Hubble Space Telescope, with the goal of determining the ...

Geological processes shaping freshwater biodiversity: a synthesis of global evidence

Biological Reviews, Volume 101, Issue 3, Page 1568-1581, June 2026.
ABSTRACT Recent genomic data highlight the key roles of geological processes in shaping the diversification and biogeography of freshwater lineages. Specifically, physical processes such as tectonic uplift, erosion, glaciation, lake formation, and sea‐level fluctuation contribute extensively to the evolution of biotic diversity within and among ...

L’agriculture à grande échelle

Revue d'anthropologie des connaissances
In the 20th and 21st centuries, agriculture underwent a process of industrialisation that profoundly transformed farms, leading to the development of huge agro-industrial complexes. This article analyses this dynamic as a change of scale, and to this end

Human brain pericytes protect the blood–brain barrier from triple‐negative breast cancer cells while promoting tumor aggressiveness

Journal of Cell Communication and Signaling, Volume 20, Issue 2, June 2026.
Abstract The majority of breast cancer‐related deaths result from metastatic progression, especially brain metastasis, associated with the poorest prognosis. Patients with triple‐negative breast cancer (TNBC) are particularly prone to developing brain metastases.

Phylogenetic and Environmental Insights Into the Biogeography of the Western Blacknose Dace, Rhinichthys obtusus

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Pleistocene glaciations have shaped freshwater fish evolution and distribution patterns across North America. This study investigated the phylogeographical history of the Western Blacknose Dace (Rhinichthys obtusus) using mitochondrial genomic data, revealing three major clades that diverged 2–1.5 million years ago during Pleistocene glaciations when ...
