NH Bond Activation of Hydrazine Using Cyclic (alkyl)(amino)carbenes and Boranes

open access: yesChemistryEurope, Volume 4, Issue 7, July 2026.
EtcAAC activates the NH bond of phenyl‐substituted hydrazines, forming EtcAAC(H)(N2HnPh3‐n) (n = 1–2). In contrast, the reaction between EtcAAC and unsubstituted hydrazine (N2H4) undergoes further decomposition. Productive NH activation of N2H4 is achieved by incorporating boranes both inter‐ and intramolecularly, leveraging their distinct binding ...

A review of high nature value farming systems in Europe: Biodiversity, ecosystem services, drivers, innovations and future prospects

open access: yesPeople and Nature, Volume 8, Issue 7, Page 2049-2064, July 2026.
Abstract Farming systems of high natural and cultural value represent approximately 30% of farmlands in the European Union and are associated with a high species and habitat diversity and/or the presence of species of European conservation concern. This study aims to synthesize the existing knowledge on the assessment of biodiversity and ecosystem ...

Extensive but fragmented evidence limits understanding of factors shaping farmers' decisions regarding diversified farming systems: A global evidence map

open access: yesPeople and Nature, Volume 8, Issue 7, Page 2212-2232, July 2026.
Abstract Diversified farming systems are increasingly recognised for their potential to enhance the sustainability and resilience of food systems. Yet it remains unclear whether empirical research adequately captures the drivers and constraints shaping farmers' decisions regarding diversified farming systems across stages of decision‐making ...

Hummingbird interaction niche packing is influenced by species richness and resource availability in the southern tropical Andes

open access: yesFunctional Ecology, Volume 40, Issue 7, Page 2275-2285, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Niche partitioning is often considered an important mechanism promoting species co‐occurrence in species‐rich communities. As species richness increases, niche partitioning may lead to different niche structures, including increased packing of species niches when the ...

Lichen bleaching as a response to long‐term experimental warming in the High Arctic

open access: yesFunctional Ecology, Volume 40, Issue 7, Page 2318-2331, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Lichens are an important component of Arctic ecosystems. Studies have indicated a decline in the abundance of Arctic lichens during recent decades, which is often attributed to competitive pressure from vascular plants.

INTERPRETAREA SINGURĂȚĂȚII CA FENOMEN PSIHOSOCIAL

open access: yesStudia Universitatis Moldaviae: Stiinte ale Educatiei, 2017
În literatura de specialitate nu există o diferențiere clară, care ar permite delimitarea fenomenului singurătății prin atribuirea unei categorii psihologice, proces psihic, pentru a identifica mecanismele singurătății, modalitățile de mani- festare a ...

Prescribed burning shows minor impacts on black pine needle terpenes and pine processionary moth larval survival

open access: yesJournal of Applied Ecology, Volume 63, Issue 7, July 2026.
Our results highlight that prescribed burning in sub‐Mediterranean pine forests does not affect their resistance to PPM in the short term, either positively or negatively, indicating that it can be implemented to reduce wildfire hazard without influencing forest susceptibility to future PPM outbreaks.

Environmental Stress Drives Plasticity in Sexual Bimaturism in the Black Soldier Fly (Hermetia illucens Linnaeus, 1758)

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 736-749, July 2026.
We measured the plasticity in sexual bimaturism (SBM; differences between sexes in the timing of sexual maturity) in the black soldier fly (BSF) by exposing larvae to nutrient availability and humidity stress. Our results show that SBM can range between protandry and protogyny depending on the environmental quality. Additionally, we found the degree of
