Spatiotemporal variability in fire foci detection in the state of Pará, Brazil [PDF]

open access: yesActa Amazonica
In the current climate change scenario, the adoption of actions aimed at reducing wildland fires and, consequently, greenhouse gas emissions is urgent.

Holocene vegetation change and fire–plant diversity shifts in Mediterranean France

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Changes in fire activity are recognized as a major threat to biodiversity and vegetation communities across the Mediterranean Basin. However, long‐term fire–vegetation interactions remain poorly investigated. Here, we combine a high‐resolution charcoal record with pollen data from the “Étang des Aulnes” lake (southern France) to reconstruct ...

‘The most advanced outpost of cultivation’: palynological evidence for cereal agriculture and population resilience in a marginal upland environment

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Upland farming in Europe is frequently assumed to have been limited and precarious, despite relict spade‐dug ridges providing firm evidence of past crop growing. Direct evidence for crop types in post‑Medieval to Modern (~since 1500 CE) uplands is rare; yet, in Ireland, relict spade‐dug ridges that date to this period are commonly interpreted ...

The constraint effect of grassland vegetation on soil wind erosion in Xilin Gol of China

open access: yesEcological Indicators, 2023
As an important part of the natural ecosystem, grassland has great significance to worldwide sustainability. The Xilin Gol grassland is the closest natural grassland to Beijing, the wind and sand conditions there can have a direct impact on Beijing's ...

Linking Ecosystem Risk, Health, Services to Ecological Security Assessment in the Yellow River Basin: Spatiotemporal Dynamics and Nonlinear Driving Characteristics

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT A scientific assessment of ecological security (ES) and its nonlinear mechanism for key driving factors in the Yellow River Basin (YRB) is of great significance for ecological protection and sustainable development. This study proposes an ES assessment framework, which links ecosystem risk (ER), ecosystem health (EH), and ecosystem services ...

Driving Mechanisms of Land Degradation Neutrality at the County Level and Zonal Strategies in the Yellow River's Key Ecological Region (Part II: Post‐Assessment Driver Analysis)

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Achieving land degradation neutrality (LDN) is critical for sustainable socio‐ecological development; however, its practical implementation is often hindered by scale mismatches between assessments and administrative units, coupled with an over‐reliance on static drivers.

The Effects of Temperature, Light Intensity, and Photoperiod on the Organic Carbon Release Rate of Sargassum horneri Seaweed

open access: yesProgress in Fishery Sciences
The ocean is the largest carbon pool on earth and plays an important role in the global carbon cycle. Marine organisms contribute over half of the global carbon fixed by photosynthesis every year.

Intercomparison of carbon‐13 and carbon‐14 tracer approaches for estimating marine calcification and net primary production

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Accurate measurements of phytoplankton net primary production (NPP) and calcification are essential for quantifying marine carbon cycling, yet in situ calcification rates remain poorly constrained. We compared 13C‐ and 14C‐based tracer methods for NPP in laboratory cultures of the diatom Chaetoceros tenuissimus and the coccolithophore ...
