Renewal bud traits as a link between whole plant traits and herbaceous species phenology

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Overwintering below‐ground buds and organs determine spring regrowth of perennial herbs in temperate regions. This effect could also manifest further in the timing and duration of plant growth and flowering and has been documented in some species and organ types ...

Record phenological responses to climate change in three sympatric penguin species

Journal of Animal Ecology, EarlyView.
This paper is impressive because we managed to monitor extensively a really difficult place to reach and operate in. We deployed 77 cameras across Antarctica and the Sub Antarctic islands to monitor three different species of penguins. We found that they are the fastest advancing vertebrates with respect to their timing of breeding.

Evaluating RADARSAT-2 for the Monitoring of Lake Ice Phenology Events in Mid-Latitudes

Remote Sensing, 2018
Lake ice is an important component in understanding the local climate as changes in temperature have an impact on the timing of key ice phenology events. In recent years, there has been a decline in the in-situ monitoring of lake ice events in Canada and

Under-Ice Phytoplankton Blooms: Shedding Light on the “Invisible” Part of Arctic Primary Production

Frontiers in Marine Science, 2020
The growth of phytoplankton at high latitudes was generally thought to begin in open waters of the marginal ice zone once the highly reflective sea ice retreats in spring, solar elevation increases, and surface waters become stratified by the addition of

Evaluation of the Interactive Multisensor Snow and Ice Mapping System (IMS) for monitoring sea ice phenology

Remote Sensing of Environment, 2014
AbstractWe present an evaluation of the Interactive Multisensor Snow and Ice Mapping System (IMS) for monitoring northern hemisphere sea ice phenology. Analysts utilize a variety of datasets to manually derive the daily extent of snow, ice, water and land, available at both 24 and 4km.

The phenological growth stages, heat unit requirement and anti‐tyrosinase activity of Greyia radlkoferi Szyszyl

Annals of Applied Biology, EarlyView.
Phenological growth stages of Greyia radlkoferi: The phenological growth stages of Greyia radlkoferi were monitored for a period of 3 years from 2018, 2019 and 2020. The flower budding, bud burst, flowering, fading, fruiting, seeding, leaf senescence and vegetative stage were recorded. The tyrosinase inhibitory activity of G.

Phenology, food webs, and fish: The effects of shifted ice phenology across multiple trophic levels

Ecosphere
Winter plays a crucial role in structuring temperate aquatic ecosystems, influencing the timing of multiple processes across trophic levels including phytoplankton blooms, zooplankton production, and the reproduction and recruitment of fish species like ...

Berberis microphylla: A species with phenotypic plasticity in different climatic conditions [PDF]

, 2018
Berberis microphylla G. Forst., commonly called as "calafate" produces small fruits with high content of carbohydrates, phenols and antioxidants. The objective of this work was to characterize the vegetative and reproductive cycle of Berberis microphylla

Climate Change, Air Quality, and Pollen Allergies—State of the Art and Recommendations for Research and Public Health

Allergy, EarlyView.
ABSTRACT Allergies are one of the major health challenges of our time, associated with a high individual burden of disease and high costs for the healthcare system. Given their prevalence, allergies are also highly relevant from a public health perspective. The development of allergic diseases is multifactorial. In addition to individual factors (e.g.,
