The equilibrium flow and mass balance of the Taku Glacier, Alaska 1950–2006 [PDF]

The Cryosphere, 2008
The Taku Glacier, Alaska has advanced 7.5 km since the late nineteenth century, while all other primary outlet glaciers of the Juneau Icefield are in retreat.

Forensic Hydraulic Analysis of Floodplain Connectivity Driven by Historical Beaver Dams in Colorado Headwater Streams

River Research and Applications, EarlyView.
ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...

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.

Monitoring glacier surface velocity in Zanskar Valley, India: Insights from DInSAR-based 2D velocity estimation

Results in Earth Sciences
Glacier surface velocity plays a crucial role in understanding glacier dynamics, climate change impacts, and water resource management. In this study, Differential Synthetic Aperture Radar Interferometry (DInSAR) and geoinformatics techniques were ...

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range

Wildlife Society Bulletin, EarlyView.
We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

Dynamics of the spatiotemporal velocity of glaciers on the eastern slope of Mount Gongga, China, under climate change

Advances in Climate Change Research
The quantitative assessment of glacier flow velocity dynamics plays a pivotal role in understanding its response mechanisms concerning climate warming. This work provides a systematic quantitative assessment of the deceleration status of glaciers in this

Modelling intra-annual dynamics of a major marine-terminating Arctic glacier

Annals of Glaciology, 2017
Significant intra-annual variability in flow rates of tidewater-terminating Arctic glaciers has been observed in recent years. These changes may result from oceanic and/or atmospheric forcing through (1) perturbations at the terminus, such as enhanced ...

Whole‐Genome Sequencing and Resequencing of Hucho bleekeri Provides Insights into Genetic Mechanisms of Environmental Adaptation

Integrative Zoology, EarlyView.
A high‐quality chromosome‐level reference genome was constructed for Hucho bleekeri. Population structure and environmental adaptation of Hucho species were revealed by whole‐genome resequencing. ABSTRACT Salmonidae represents an important family in the study of genome evolution following genome duplication.

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

Boreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

Ice Flow Measurements on the East Coast of Lutzow-Holm Bay, Antarctica (Reports of the Japanese Antarctic Research Expedition)

Antarctic Record, 1972
An attempt was made at the measurements of surface velocities of ice flow in several places along the east coast of Lutzow-Holm Bay in 1960 and 1961. Difficulties in preserving stakes and in selecting suitable sites for surveying and the limited time ...
