The relationship between cellular protein content and selenium accumulation in freshwater microalgae

Integrated Environmental Assessment and Management, EarlyView.
Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

Atmospheric Lamb wave pulse and volcanic explosivity index following the 2022 Hunga Tonga (South Pacific) eruption

Frontiers in Earth Science, 2023
The atmospheric Lamb wave induced by the Hunga Tonga (South Pacific) volcanic eruption on 15 January 2022 was recorded as atmospheric pressure fluctuations at various meteorological stations around the globe, and persisted for several days after the ...

The Impacts of Southwest Indian Ocean Tropical Cyclones on Transient Weather in Réunion

International Journal of Climatology, EarlyView.
Tropical cyclones which make passage near Réunion can have significant impacts on transient weather relative to long‐term means on the island. In this paper, these impacts were determined by a topological analysis of non‐landfalling tropical cyclones. The relationship between storm intensity, distance, duration, and seasonality plays an equal role in ...

High-latitude volcanic eruptions in the Norwegian Earth System Model: the effect of different initial conditions and of the ensemble size [PDF]

Tellus: Series A, Dynamic Meteorology and Oceanography, 2015
Large volcanic eruptions have strong impacts on both atmospheric and ocean dynamics that can last for decades. Numerical models have attempted to reproduce the effects of major volcanic eruptions on climate; however, there are remarkable inter-model ...

Climatic Impact of Volcanic Eruptions [PDF]

The Scientific World JOURNAL, 2002
Volcanic eruptions have the potential to force global climate, provided they are explosive enough to emit at least 1–5 megaton of sulfur gases into the stratosphere. The sulfuric acid produced during oxidation of these gases will both absorb and reflect incoming solar radiation, thus warming the stratosphere and cooling the Earth’s surface.

Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

Journal of Quaternary Science, EarlyView.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.

The Potential of Stratospheric Aerosol Injection to Reduce the Climatic Risks of Explosive Volcanic Eruptions

Geophysical Research Letters
Sulfur‐rich volcanic eruptions happen sporadically. If Stratospheric Aerosol Injection (SAI) were to be deployed, it is likely that explosive volcanic eruptions would happen during such a deployment.

Can DNA from wet, temperate soils be used for palaeoecological reconstruction?

Journal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary ancient DNA in well‐dated contexts (sedaDNA) has great potential as a palaeoecological proxy. A few studies have attempted palaeoecological reconstructions using sedaDNA from soil; these studies have been mainly restricted to cold and/or dry soils.

Initial colonization by bryophytes and ferns during primary succession on Nishinoshima, Japan

Nordic Journal of Botany, EarlyView.
Volcanic islands that have experienced complete vegetation loss following recent eruptions provide rare opportunities to observe the earliest stages of ecosystem recovery. Nishinoshima, an oceanic island located approximately 1000 km south of mainland Japan, underwent major volcanic activity between 2013 and 2020, eradicating all pre‐existing ...

Crisis Preparation, Capacity Building, and Community Resilience: Lessons From Maui

Nonprofit Management and Leadership, EarlyView.
ABSTRACT The 2023 Maui wildfires provide a unique context to explore the impact of nonprofit crisis networks taking a proactive role in community crisis response, leveraging resources, expertise, and networks. The Hawaiʻi Community Foundation (HCF) has been a key player in Maui's local response, providing critical support, mobilizing volunteers, and ...
