The oxygen‐sensing FixLJ represses nitrogen fixation in Rhodopseudomonas palustris in response to oxygen

open access: yesmLife, EarlyView.
Abstract Biological nitrogen fixation in symbiotic diazotrophs is subject to oxygen regulation by an oxygen‐sensing FixLJ two‐component system under micro‐oxic conditions. However, it remains unclear whether this mechanism is conserved in free‐living diazotrophs.

Exploitation of Rabbits at the Dawn of the Holocene: Evidence From the Font Voltada Site (Northeastern Iberia) Using Comparative Neotaphonomic Models

open access: yesInternational Journal of Osteoarchaeology, EarlyView.
ABSTRACT During the transition from the Pleistocene to the Holocene, hunter‐gatherer societies in the northeastern Iberian Peninsula increased the number of settlements and broadened their subsistence strategies. This period is marked by the appearance of terrestrial snail accumulations attributable to human harvesting, the expansion of specialized ...

Deep silicon etching: STiGer vs. BOSCH

open access: yes, 2016
International audienceSilicon deep etching is widely used in microelectronics and micro-electro-mechanical systems (MEMS). To achieve deep etching, cryogenic and Bosch processes are commonly used.

Connecting the distribution and diversification of marine plants

open access: yesOikos, EarlyView.
Integration of the evolutionary history with distribution of extant species is necessary to explain present‐day diversity, particularly for ‘foundation' species, such as seagrasses, which create habitats of socioecological relevance. Here, we resolved if varying evolutionary history of seagrass families has imprinted the distribution ranges of extant ...

When wolves aren't enough: revisiting trophic cascades in northern Wisconsin

open access: yesOikos, EarlyView.
Elimination of top predators has allowed large herbivores to flourish in many terrestrial ecosystems, transforming food webs and ecosystem functions. Restoration of large predator communities is hoped to reverse negative effects of this trophic downgrading, but evidence for such effects is elusive.

Examining the multi‐disciplinary origins of biophobia towards threatening and non‐threatening wildlife in a highly urbanised city in China

open access: yesPeople and Nature, EarlyView.
Abstract Urbanisation is reshaping how people experience wildlife, reducing our shared spaces with local biodiversity. Fewer opportunities for human–wildlife interactions weaken our emotional attachments to nature and precipitate a loss of species knowledge and familiarity.

Genetic analysis of primary lung interdigitating dendritic cell sarcomas

open access: yesThe Journal of Pathology, EarlyView.
Abstract Interdigitating dendritic cell sarcomas (IDCSs) are rare tumors that commonly arise in the hematopoietic system and rarely outside. The genetic drivers of IDCS carcinogenesis are unknown; therefore, therapeutic options are limited. We investigated somatic gene mutations and copy‐number alterations (CNAs) in nine IDCSs arising in the lung by ...
