Integrating ecological feedbacks across scales and levels of organization
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

LA PROTECTION JURIDIQUE INTERNATIONALE DE LA BIODIVERSITE MARINE
Il s’agit d’un article sur le droit international de l’environnement relatif à la protection des ressources biologiques des océans. Il a été conçu pour traiter de l’importance des impacts environnementaux lors de l’utilisation de la biodiversité marine comme matière première de la production industrielle, en analysant les instruments juridiques ...

Anticipating cosmetic emulsion stability using a novel multi‐analytical approach
A novel combination of granulometry, turbidimetry and rheology enables early detection of cosmetic emulsion instability—reducing assessment time from 30 to 8 days. This rapid method distinguishes stable from unstable emulsions under identical conditions, offering a powerful tool for formulation screening and industrial quality control.

The material has no significant difference in captures (non‐shiny cotton‐polyester screens vs. the shiny polyethylene screens), but the vertical screen attracted significantly more G. tachinoides for each type of material. Full white horizontal screen was significantly lower than the reference WATT.

Beyond species means – the intraspecific contribution to global wood density variation
Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from

Random walk with heavy tail and negative drift conditioned by its minimum and final values
We consider random walks with finite second moment which drifts to $-\infty$ and have heavy tail. We focus on the events when the minimum and the final value of this walk belong to some compact set. We first specify the associated probability.

ABSTRACT The European perch Perca fluviatilis and pikeperch Sander lucioperca can co‐occur, potentially competing for food resources. However, few studies have addressed the potential feeding competition between these species. We used carbon and nitrogen stable isotope analysis to assess the potential trophic competition between these species in two ...
