Annual–Perennial Forage Mixtures Improve Forage Productivity and Soil Quality in Patchily Degraded Cultivated Pastures Under Grazing Management

open access: yesLand Degradation &Development, Volume 37, Issue 15, Page 11036-11047, September 2026.
ABSTRACT Patchy degradation of cultivated pastures under long‐term grazing is a serious issue limiting grassland productivity. The use of annual and perennial legume–grass mixtures, which offer complementary functional advantages, may provide a practical reseeding‐based approach for improving patchily degraded cultivated pastures; however, limited ...

A Decade of Biogeochemical Monitoring in the Tropical Urban Saigon‐Dong Nai River‐Estuary Continuum, Vietnam

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Tropical Southeast Asian estuaries remain underrepresented in global water quality archives, limiting regional comparisons and the development of predictive biogeochemical models for monsoon‐driven coastal systems. To address this observational gap, this paper presents a quality‐controlled, 10‐year (2015–2025) biogeochemical data set for the ...

Temperature, but not acidification, influences the growth and lipid profile of juvenile sand whiting, Sillago ciliata (Cuvier 1829)

open access: yesJournal of Fish Biology, Volume 109, Issue 3, Page 1507-1516, September 2026.
Abstract Seafood provides an essential source of macro‐ and micronutrients for coastal communities worldwide. Climate change is a key threat to seafood security, altering the sizes, abundances, distributions, physiology and ecological interactions of fisheries species, and increasingly, there is evidence of impacts to seafood nutritional quality.

Zagros Restoration: Smart Choices for Oak Forests

open access: yesLand Degradation &Development, Volume 37, Issue 14, Page 10284-10307, 30 August 2026.
ABSTRACT Widespread forest degradation across the northern Zagros region of Iran driven by both human activity and natural processes has created an urgent need for targeted afforestation and forest enrichment strategies. Hence, the aim of this study was identifying the most suitable native tree and shrub species for restoring degraded forest areas in ...
