Spatiotemporal characteristics of Qinghai Lake ice phenology between 2000 and 2016 [PDF]

Journal of Geographical Sciences, 2019
Lake ice phenology is considered a sensitive indicator of regional climate change. We utilized time series information of this kind extracted from a series of multi-source remote sensing (RS) datasets including the MOD09GQ surface reflectance product, Landsat TM/ETM+ images, and meteorological records to analyze spatiotemporal variations of ice ...

On the phenology and seeding potential of sea-ice microalgal species

Elementa: Science of the Anthropocene, 2022
Sea ice is an important habitat for a wide variety of microalgal species. Depending on the species composition, sea ice can be a seeding source for pelagic phytoplankton blooms after ice melt in spring. Sea-ice algal communities were studied over 2 full winter seasons in 2014 and 2016 at Rothera Research Station, situated at the Western Antarctic ...

Projected Warming of the Southern Ocean Disrupts Embryonic Development and Hatch Timing in Antarctic Fish

Global Change Biology Communications, EarlyView.
Embryos are particularly sensitive to thermal challenge. Antarctic fish embryos raised at projected Southern Ocean temperatures hatch during the winter, have a high incidence of morphological abnormalities, have shorter body lengths, and express genes indicative of cellular stress.

Implications of climate change for coastal and inter-tidal habitats in the UK [PDF]

, 2013
Coastal habitats are diverse and vary in the extent to which they are shaped by physiographic processes, such as wave action, wind, tides and sediment availability, and the relative influence of terrestrial and marine environments, e.g.

Understanding the evolution of native pinewoods in Scotland will benefit their future management and conservation [PDF]

, 2010
Scots pine (Pinus sylvestris L.) is a foundation species in Scottish highland forests and a national icon. Due to heavy exploitation, the current native pinewood coverage represents a small fraction of the postglacial maximum.

Compound Hot‐Dry Days (CHDDs) and Their Implications on Maize Yields in the Free State Province, South Africa

International Journal of Climatology, EarlyView.
Compound hot‐dry events occurring during the maize growing period are increasing significantly (p < 0.05) with time, with the median values ranging from 93 to 120 days. El Niño Southern Oscillation (ENSO) influences the variability of compound hot‐dry events with high significance (p < 0.05) positive Pearson correlation.

Despite a century of warming, increased snowfall has buffered the ice phenology of North America’s largest high-elevation lake against climate change

Environmental Research Letters
Lakes are sentinels of environmental change. In cold climates, lake ice phenology—the timing and duration of ice cover during winter—is a key control on ecosystem function.

Phenological Shifts in Wood Formation Tracked by Frost Rings Across Two Centuries. [PDF]

Glob Chang Biol
Rapid warming is reshaping plant phenology across ecosystems. We present an indirect retrospective approach to infer cambial phenology by analysing the timing and occurrence of frost rings in three Alpine conifers. We found that the cold spells responsible for frost ring formation typically involve temperature dropping below freezing for an average of ...

Climate regulates alpine lake ice cover phenology and aquatic ecosystem structure [PDF]

Geophysical Research Letters, 2016
AbstractHigh‐elevation aquatic ecosystems are highly vulnerable to climate change, yet relatively few records are available to characterize shifts in ecosystem structure or their underlying mechanisms. Using a long‐term data set on seven alpine lakes (3126 to 3620 m) in Colorado, USA, we show that ice‐off dates have shifted 7 days earlier over the past
