A multi‐scale assessment of interior Douglas‐fir tree mortality for hazard and risk assessments

open access: yesEcosphere, Volume 17, Issue 1, January 2026.
Abstract Land managers use hazard (susceptibility) and risk rating systems to guide the application of forest management treatments that aim to reduce future damages to forests. Rating systems are typically designed for individual damage agents, but tree mortality often results from multiple agents without a clear proximate cause.

Operational sex ratio bias due to sex‐specific cohort splitting in response to predation

open access: yesEcosphere, Volume 17, Issue 1, January 2026.
Abstract The operational sex ratio (OSR), that is, the local ratio of fertilizable females to sexually active males at any given time, is of key importance for the strength of sexual selection and the reproduction of populations. We hypothesize that sex‐specific cohort splitting, that is, when one sex mostly metamorphoses while the other mostly enters ...

Bioactive Compounds From Agri‐Food By‐Products: Advancements in Environmental Sustainability and Bioeconomic Progress

open access: yesEngineering Reports, Volume 8, Issue 1, January 2026.
Agri‐food by‐products are sustainably transformed into high‐value bioactive compounds through advanced green extraction technologies. This valorization supports circular economy goals and promotes environmental and bioeconomic progress. ABSTRACT The rapid growth of agri‐food industries has led to an alarming increase in waste generation, posing ...

Reproductive flexibility in a single‐brooded migrant: can the European roller Coracias garrulus adapt to extreme weather events?

open access: yesJournal of Avian Biology, Volume 2026, Issue 1, January 2026.
Global climate change has intensified extreme weather events, including short‐duration but intense rainfall, which can significantly impact avian reproduction. This study examines the effects of extreme rainfall on the reproductive phenology and performance of the European roller Coracias garrulus, a single‐brooded migratory bird, in a semiarid ...

Waiting for the rains: An attempt to evaluate the efficiency of the large Roman cistern at Barbariga Stancija (Casematte, Istria, Croatia)

open access: yesJournal of Quaternary Science, Volume 41, Issue 1, Page 99-117, January 2026.
ABSTRACT Access to freshwater has always been a critical factor in sustaining human settlements, especially in regions with limited water resources. In the Mediterranean region, where dry summers and karst landscapes limit water availability, ancient societies developed advanced methods for collecting and storing rainwater. Among these, cisterns played

Analysis of triacylglycerol and phospholipid sn‐positional isomers by liquid chromatographic and mass spectrometric methodologies

open access: yesMass Spectrometry Reviews, Volume 45, Issue 1, Page 4-36, January/February 2026.
Abstract Analysis of triacylglycerol (TG) and phospholipid sn‐positional isomers can be divided into two main categories: (a) direct separation by chromatography or other means such as ion mobility mass spectrometry and (b) quantification of regioisomer ratios by structurally informative fragment ions with mass spectrometric methods.
