Little Ice Age cooling promoted peat initiation and permafrost development at the southern permafrost margin. Rapid carbon accumulation was sustained by permafrost‐suppressed decay and high photosynthetically active radiation, but recent warming‐driven drying is reducing carbon accumulation and increasing carbon‐loss risk.

The aim of the study was to propose a so called dynamic curve for identification of hydrological conditions of peatland formation. This method facilitates interpretation of accumulation processes based on sequence of biogenic sediments depending on ...

Many plant species worldwide are struggling to regenerate due to the ongoing effects of climate change. These effects appear to be further exacerbated by the loss of keystone megafauna, which were important seed dispersers. By identifying the traits commonly seen in seeds spread by modern elephants, it is possible to predict which species likely ...

Resumen. Las reconstrucciones del pasado se tornan más objetivas si se considera el mayor número de indicadores posible. En especial, las reconstrucciones ambientales de los últimos 20.000 años son importantes para el entendimiento de la dinámica de los ...

ABSTRACT Natural inland wetlands in Southeast Asia provide key biodiversity, hydrological, carbon‐storage and livelihood functions, but are increasingly affected by land‐use change, fire, hydrological modification and climate change and variability.

Abstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.

Climate change is profoundly affecting mountain areas. While glacier retreat is highly visible, the underground cryosphere, including cave ice deposits, faces less apparent but equally concerning threats.

Geomorphological controls on the re-vegetation of erosion gullies in blanket peat: implications for bog restoration [PDF]
This paper describes the natural re-vegetation of eroded blanket peat gullies in the Dark Peak National Park, Southern Pennines (UK). Sequences derived from the plant macrofossil records of nine peat cores indicate a two-phase process of re-vegetation ...

The Cretaceous and Palaeogene floras of western Greenland that were initially described as part of the classical work “Flora fossilis arctica” by Oswald Heer in the 19th century are currently under revision.
