New constraints on the postglacial evolution of Lago Maggiore, Northern Italy

Journal of Quaternary Science, EarlyView.
ABSTRACT Lago Maggiore is situated in an overdeepened valley reach at the southern margin of the European Alps, and its thick sediment infill allows the reconstruction of the postglacial valley and lake evolution. We study here the sedimentary succession in the lower Ossola Valley, which is infilled by ~500 m of deposits. In a marginal position, a core

Rapid sequestration of rock avalanche deposits within glaciers [PDF]

, 2015
Topographic development in mountainous landscapes is a complex interplay between tectonics, climate and denudation. Glaciers erode valleys to generate headwall relief, and hillslope processes control the height and retreat of the peaks.

International Workshop Examines Debris‐covered Glaciers

Eos, Transactions American Geophysical Union, 2001
Glaciers are important features in climate studies. The smaller alpine glaciers respond to climatic variation in ways visible during the human lifetime. Glacial processes modify the landscape leaving signatures of past climatic conditions. The large ice sheets have an important role in the global heat and water balance, which in turn play a major role ...

Comparison of particle properties and biovolume estimates from FlowCam and microscopy for kettle hole phytoplankton communities

Limnology and Oceanography: Methods, EarlyView.
Abstract The integration of high‐throughput image–based flow cytometry into routine phytoplankton assessment requires rigorous evaluation against established microscopy techniques. As method agreement is often site‐ and species‐specific, case‐by‐case validation is essential to successfully adopt emerging methods.

Digital fire technologies and community networks: Cultivating just sociotechnical practices for living with planetary change

People and Nature, EarlyView.
Abstract Fires are expanding in frequency and intensity worldwide due to climate change and land‐use transformations. At the same time, fire often plays a regenerative role in ecosystems. Traditional and cultural practices incorporate fire use for landscape management and landscape renewal. In this complex matrix of fire ecologies, digital technologies

Ablation process of debris-covered glaciers.

Journal of the Japanese Society of Snow and Ice, 2001
岩屑に覆われた永河の融解過程は複雑で観測が困難なためこれまで詳細な研究が少なかった.当初の研究は岩屑に覆われた部分に重点がおかれ,均一な厚さの岩屑に覆われた氷雪の融解についての実験的研究が多くの研究者によって行われてきた.実際の氷河では岩屑の粒径,組成,厚さなどの分布を広い面にわたって把握することが困難であった.そこで近年発達した衛星画像で得られた表面温度分布から消耗域全体の融解量を推定するモデルが開発された.このモデルにより推定された値は実際の岩屑に覆われた氷河の融解量よりも大きくなった.この原因は岩屑氷河の池や氷壁の部分で大きな熱の吸収が氷河の融解を促進させていることが一因と考えられる.

Composite Microgels with Dynamically Switchable Stiffness

Small, EarlyView.
Composite microgels comprising alginate and mucin are produced, in which covalent and ionics cross‐links are combined such that the mechanical properties of the microgels can be tuned on demand at any time post‐production. In addition, the mucin component conveys bacteria‐repellent properties to the cytocompatible microgels.

Internal structure and water routing of an ice-debris landform assemblage using multiple geophysical methods in the semiarid Andes

Frontiers in Earth Science, 2023
Rock glaciers are the most abundant (peri) glacial landform in the semiarid Andes (SA, 29–34°S), covering about three times the area of mountain glaciers.

Cytogenotoxic and Molecular Assessment of Pyrethrins on Non‐Target Allium cepa Roots

Environmental Toxicology, EarlyView.
ABSTRACT The pyrethrins, which form a part of naturally occurring insecticidal chemicals derived from chrysanthemum flowers, not only provide rapid knockdown of a broad spectrum of insect pests but are also widely used in integrated pest management due to a generally favorable safety profile, largely attributed to low mammalian toxicity.
