Increasing Tephra Deposition in Northeastern North America Points to Atmospheric Circulation Changes at the Early Mid Holocene Transition Open
The number of cryptotephra (non‐visible volcanic ash) records from northeastern North America is unique in the continent. The resulting tephrostratigraphic framework includes ash deposits sourced from volcanic arcs across the Northern Hemi…

Enhanced mercury deposition in Arctic Alaskan lake sediments coincides with early Holocene hydroclimate shift Open
Substantial amounts of mercury (Hg) are projected to be released into Arctic watersheds as permafrost thaws amid warmer and wetter conditions. This may have far-reaching consequences because the highly toxic methylated form of Hg biomagnif…

A Policy Relevant Study of the Contradiction Between Market Economy and Traditional Socio-Economic Development in the Russian Arctic Open
The development of the Arctic is a priority for the Russian government as it has great economic potential. However, the benefits for indigenous population are unclear, as economic expansion affects traditional livelihoods and social develo…

Influences of sea level changes and volcanic eruptions on Holocene vegetation in Tonga Open
Here, we investigate Mid‐ to Late‐Holocene vegetation changes in low‐lying coastal areas in Tonga and how changing sea levels and recurrent volcanic eruptions have influenced vegetation dynamics on four islands of the Tongan archipelago (S…

The drivers of plant community composition have shifted from external to internal processes over the past 20,000 years Open
Internal and external factors regulating the past composition of plant communities are difficult to identify in palaeo-vegetation records. Here, we develop an index of relative entropy of community assembly, which applies to changes in the…

Long‐term trajectories of non‐native vegetation on islands globally Open
Human‐mediated changes in island vegetation are, among others, largely caused by the introduction and establishment of non‐native species. However, data on past changes in non‐native plant species abundance that predate historical document…

Island ecosystem responses to the Kuwae eruption and precipitation change over the last 1600 years, Efate, Vanuatu Open
Introduction Islands of the Southwest Pacific are exposed to geologic and climate-related disturbances that occur on a range of timescales and which probably affect, to varying degrees, their terrestrial ecosystems. Over the past ∼1100 yea…

Lake and Peat Records of Climate Change and Archaeology Open
Lake and peat sediments are frequently used to reconstruct palaeoclimate records from all continents using a variety of proxy techniques. This chapter explores the advances that have occurred in the last 20 or more years for using lake and…

Taming Fogo Island: Late-Holocene volcanism, natural fires and land use as recorded in a scoria-cone sediment sequence in Cabo Verde Open
Cabo Verde remained uninhabited until 1460 CE, when European sailors founded a settlement in Santiago, and soon after in Fogo island. The degree to which different island ecosystems in Cabo Verde have been transformed by humans remains unc…

Paleoeconomy more than demography determined prehistoric human impact in Arctic Norway Open
Population size has increasingly been taken as the driver of past human environmental impact worldwide, and particularly in the Arctic. However, sedimentary ancient DNA (sedaDNA), pollen and archaeological data show that over the last 12,0…

Peppers in Diet: Genome-Wide Transcriptome and Metabolome Changes in Drosophila melanogaster Open
The habanero pepper (Capsicum chinense) is an increasingly important spice and vegetable crop worldwide because of its high capsaicin content and pungent flavor. Diets supplemented with the phytochemicals found in habanero peppers might ca…

Developing Transdisciplinary Approaches to Sustainability Challenges: The Need to Model Socio-Environmental Systems in the Longue Durée Open
Human beings are an active component of every terrestrial ecosystem on Earth. Although our local impact on the evolution of these ecosystems has been undeniable and extensively documented, it remains unclear precisely how our activities ar…

Pleistocene glacial and interglacial ecosystems inferred from ancient <span>DNA</span> analyses of permafrost sediments from Batagay megaslump, East Siberia Open
Pronounced glacial and interglacial climate cycles characterized northern ecosystems during the Pleistocene. Our understanding of the resultant community transformations and past ecological interactions strongly depends on the taxa found i…

Climate and human exploitation have regulated Atlantic salmon populations in the River Spey, Scotland, over the last 2000 years Open
Historical salmon catch records suggest that climatic variability, and more recently human exploitation, control patterns of abundance in Atlantic salmon populations. We present the first long-term (2000-year) reconstruction of Atlantic Sa…

Late Pleistocene shrub expansion preceded megafauna turnover and extinctions in eastern Beringia Open
Significance Megafauna strongly influence vegetation structure, and population declines can alter ecosystem functioning. Overhunting of grazing megafauna is argued to have driven the collapse of widespread, northern steppe-tundra and its r…
