Assessing the Performance of Methods for Monitoring Ice Phenology of the World’s Largest High Arctic Lake Using High-Density Time Series Analysis of Sentinel-1 Data

Remote Sensing, 2020
Lake ice is a dominant component of Canada’s landscape and can act as an indicator for how freshwater aquatic ecosystems are changing with warming climates.

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.

Modeling Arctic sea‐ice algae: Physical drivers of spatial distribution and algae phenology [PDF]

Journal of Geophysical Research: Oceans, 2017
AbstractAlgae growing in sea ice represent a source of carbon for sympagic and pelagic ecosystems and contribute to the biological carbon pump. The biophysical habitat of sea ice on large scales and the physical drivers of algae phenology are key to understanding Arctic ecosystem dynamics and for predicting its response to ongoing Arctic climate change.

Leveraging machine learning and citizen science data to describe flowering phenology across South Africa

PLANTS, PEOPLE, PLANET, EarlyView.
Recent shifts in flowering times are an index of, and a response to, human driven climate change. However, most information on these flowering changes is heavily skewed to the northern hemisphere. This imbalance limits our understanding of how climate change is affecting ecosystems, including the mismatches of flowering times between species, increased

Solar farms can mitigate negative impacts of whiplash weather on plant communities in a dryland ecosystem

PLANTS, PEOPLE, PLANET, EarlyView.
Utility‐scale solar energy (USSE) development generates novel questions regarding coupling clean energy production with terrestrial ecosystem services (e.g., forage production, pollinator support). We found that a USSE array sited in a fallowed cropland maintained a reseeded native plant community even a decade post‐restoration and that the array ...

A satellite-based ice fraction record for small water bodies of the Arctic Coastal Plain (2017 to 2023) [PDF]

Earth System Science Data
Ice cover of water bodies in the northern high latitudes (NHL) is highly sensitive to the changing climate, and its dynamics exert substantial impacts on the NHL ecosystems, hydrological processes, and the carbon cycle. Yet, operational quantification of

Long term trend of chemical oxygen demand in Saroma-ko Lagoon, Japan; possible effects of climatic warming [PDF]

, 2008
A trend of shortening duration of ice coverage has been reported in many rivers, ponds and lakes around the world due to climatic warming. The shortening will have much influence on organic production due to the greater supply of light intensity and ...

Volume-Mediated Lake-Ice Phenology in Southwest Alaska Revealed through Remote Sensing and Survival Analysis

Water
Lakes in Southwest Alaska are a critical habitat to many species and provide livelihoods to many communities through subsistence fishing, transportation, and recreation. Consistent and reliable data are rarely available for even the largest lakes in this

Past, present and future of local crop evolution

PLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).
