Connecting Resource Tracking by Frugivores to Temporal Variation in Seed Dispersal Networks

open access: yesFrontiers in Ecology and Evolution, 2017
Mutualistic interactions between species are crucial for the maintenance and functioning of the community. Current research has shown the importance of not only understanding the structure of these mutualistic interaction networks but also their temporal

Automated FRAP microscopy for high‐throughput analysis of protein dynamics in chromatin organization and transcription

open access: yesFEBS Open Bio, EarlyView.
RoboMic is an automated confocal microscopy pipeline for high‐throughput functional imaging in living cells. Demonstrated with fluorescence recovery after photobleaching (FRAP), it integrates AI‐driven nuclear segmentation, ROI selection, bleaching, and analysis.

Temporal variation of iodine in Danish groundwater

open access: yes, 2023
Iodine is an essential element for human health, and both high and low iodine intake could have negative health outcomes. The spatial variation of iodine in Danish groundwater has been studied before, but to the author’s knowledge, this is the first time

LA SITUATION DES ÉCREVISSES EN FRANCE RÉSULTATS DES ENQUÊTES NATIONALES RÉALISÉES ENTRE 1977 ET 2006 PAR LE CONSEIL SUPÉRIEUR DE LA PÊCHE

open access: yesKnowledge and Management of Aquatic Ecosystems, 2007
Depuis la fin du XIX° siècle, la distribution des écrevisses en France a connu de profonds bouleversements, et l’introduction d’écrevisses allochtones en provenance essentiellement du continent nord-américain, a irrémédiablement modifié le paysage ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Terrestrial water storage change from temporal gravity variation

open access: yes, 2009
Recent progress in accurately monitoring temporal gravity variations by means of superconducting gravimeters and satellite geodesy provides unprecedented opportunities in closing the water balance.

Age-Specific Fitness Components and Their Temporal Variation in the Barn Owl

open access: yes, 2007
Theory predicts that temporal variability plays an important role in the evolution of life histories, but empirical studies evaluating this prediction are rare.

Spatio-temporal malaria transmission patterns in Navrongo demographic surveillance site, northern Ghana [PDF]

open access: yes, 2013
The relationship between entomological measures of malaria transmission intensity and mortality remains uncertain. This is partly because transmission is heterogeneous even within small geographical areas.

Strategy and Metrological Support for Indoor Radon Measurements Using Popular Low-Cost Active Monitors with High and Low Sensitivity

open access: yesSensors
Traditionally, for indoor radon testing, predominantly passive measurements have been used, typically applying the solid-state alpha track-etch method for long-term and the charcoal method for short-term measurements.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...
