Playground tree diversity: A driver of well‐being in preschool children

open access: yesPeople and Nature, Volume 8, Issue 2, Page 486-503, February 2026.
Abstract Urban greenspaces benefit mental health in adults, with increasing evidence that biodiversity might also play a role. However, we know very little about the impact of urban biodiversity on preschool children's well‐being, despite the critical importance of the formative years.

Registration of ‘Renovation’ White Clover

open access: yesJournal of Plant Registrations, 2017
‘Renovation’ (Reg. No. CV‐9, PI 680615), is a large‐leaved, synthetic intermediate type white clover (Trifolium repens f. hollandicum Erith ex Jav. & Soo) cultivar derived after hybridizing (i.e., population crosses) random, individual plants from a naturalized ecotype population from Oklahoma with those from the ‘Regal’, ‘Patriot’, ‘Tillman’, and ‘

N2O emission from grass-clover swards is largely unaffected by recently fixed N2 [PDF]

open access: yes, 2004
The contribution of biologically fixed dinitrogen (N2) to the nitrous oxide (N2O) production in grasslands is unknown. To assess the contribution of recently fixed N2 as a source of N2O and the transfer of fixed N from clover to companion grass, mixtures

Agricultural System Resilience of Industrial Hemp: An Exploratory Value Web Analysis in the Swabian Alb

open access: yesGCB Bioenergy, Volume 18, Issue 2, February 2026.
This study assessed the industrial hemp value web resilience in the Swabian Alb, Southern Germany, where regional implementation remains limited despite hemp's bioeconomy potential. Using an indicator framework and stakeholder interviews, the research found the small, fluctuating cultivation area (e.g., 25 ha in 2024) focuses on hemp seed valorisation;

The effects of nitrate nitrogen and phosphate on the nodulation and nitrogen fixation of white cliver (Trifolium repens L.): a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science at Massey University [PDF]

open access: yes, 1974
It is a well established fact that the presence of nitrate ions can depress nodule development on legume roots, but recent studies in Queensland (Gates, 1970) have shown that this sensitivity can be ameliorated if phosphate levels are maintained at a ...

Antireflux Surgery for Barrett's Esophagus: Where Do We Stand in Preventing Esophageal Adenocarcinoma?

open access: yesAnnals of the New York Academy of Sciences, Volume 1556, Issue 1, February 2026.
Esophageal adenocarcinoma (EAC) often develops from gastroesophageal reflux disease (GERD), with Barrett's esophagus (BE) as its main precursor. While proton pump inhibitors manage GERD symptoms, their preventive role in EAC remains unclear. This review summarizes advances in diagnosing BE and evaluates anti‐reflux surgery for its potential to prevent ...
