Long‐Term Analysis of Winter Wheat Yield and Climatic Influences in Ukraine

International Journal of Climatology, EarlyView.
Long‐term field data (1968–2024) show that winter wheat yields in central Ukraine increased despite warming, but yield stability declined. Rising temperatures, more frequent soil moisture droughts and shortened winter calm increasingly limit productivity.

Lake Ice Phenology Extraction using Machine Learning Methodology

IOP Conference Series: Earth and Environmental Science, 2020
Abstract Lake-ice phenology is one of the key cryosphere indicators. Based on changes in time series of daily lake ice coverage and the microwave brightness temperature, two machine-learning methods were selected for estimating the phenology of lake ice.

Holocene vegetation dynamics of Grande Terre (Kerguelen Islands) inferred from sedimentary ancient DNA

Journal of Quaternary Science, EarlyView.
ABSTRACT While the Antarctic region has experienced significant climatic changes over the Holocene, few high‐resolution records have examined their effects on the local biota. In order to understand past ecological shifts and forecast future changes, it is important to obtain high‐resolution palaeoecological records from this region.

How to Choose Your Statistical Test Before You Run It: A Decision‐Based Guide to Statistical Analysis in Aquatic Sciences for Young Scientists

Limnology and Oceanography Bulletin, EarlyView.
Abstract Statistical analysis is a cornerstone of scientific research, yet young researchers in aquatic sciences often struggle when analyses begin without a clearly defined research question or a solid understanding of the data structure. This disconnect between data collection and analytical decision‐making recurrently drives unreliable findings ...

Phenology of alpine zooplankton populations and the importance of lake ice-out

Journal of Plankton Research, 2020
AbstractThe prolonged ice cover inherent to alpine lakes incurs unique challenges for aquatic life, which are compounded by recent shifts in the timing and duration of ice cover. To understand the responses of alpine zooplankton, we analyzed a decade (2009–2019) of open-water samples of Daphnia pulicaria and Hesperodiaptomus shoshone for growth ...

Integrating and assessing metacommunity drivers of ecosystem function and resilience in benthic algal systems

Oikos, EarlyView.
Understanding the scales and mechanisms by which species composition interacts with ecosystem functions is critical for forecasting the effects of environmental perturbations on ecosystem services. However, the linkages between what regulates the ecosystem functions of dispersal‐capable networks of communities (metacommunities) and what regulates a ...

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.

Mesoclimatic origin affects alpine plant germination but not its plasticity

Oikos, EarlyView.
Mountain ecosystems are disproportionately exposed to global warming, which may put alpine plant species in particular at risk. Plant species' migration and persistence depend on successful seed regeneration, with demographic traits such as germination being strongly sensitive to both present and ancestral climate.
