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.

Soil respiration in a northeastern US temperate forest: a 22‐year synthesis [PDF]

, 2013
To better understand how forest management, phenology, vegetation type, and actual and simulated climatic change affect seasonal and inter‐annual variations in soil respiration (Rs), we analyzed more than 100,000 individual measurements of soil ...

Leaf longevity and structure, fruit mass and phenology in 52 cultivated varieties and wild accessions of olive

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Although phenology has long been recognized as a critical feature for the adaptation of organisms to their local environment, until recently, phenological events have seldom been considered in the broader context of trait‐based ecology.

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

A longer vernal window: The role of winter coldness and snowpack in driving spring thresholds and lags [PDF]

, 2017
Climate change is altering the timing and duration of the vernal window, a period that marks the end of winter and the start of the growing season when rapid transitions in ecosystem energy, water, nutrient, and carbon dynamics take place.

Below the leaves: Integrating above‐ and below‐ground phenology for earth‐system predictability

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Almost every aspect of biological systems has phenology—a pattern in activity or function linked to annual cycles. Most terrestrial phenology research focusses on leaves, the onset of leaf out or senescence.

Shared leadership can promote success in collaborative research networks in ecology

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract While collaborative science is becoming the norm in ecology, many ecologists participating in collaborations are less aware of the body of research that studies the processes by which collaborative teams organize and communicate.

Approximation of ice phenology of Maine lakes using Aqua MODIS surface temperature data

Ecosphere
Studies of lake ice phenology have historically relied on limited in situ data. Relatively few observations exist for ice out and fewer still for ice in, both of which are necessary to determine the temporal extent of ice cover. Satellite data provide an

Changes in Snow Phenology from 1979 to 2016 over the Tianshan Mountains, Central Asia [PDF]

, 2019
Snowmelt from the Tianshan Mountains (TS) is a major contributor to the water resources of the Central Asian region. Thus, changes in snow phenology over the TS have significant implications for regional water supplies and ecosystem services.
