Surface primary producer phenology in Dease Strait, NU, Canada, examined using submersed oceanographic sensors and satellite remote sensing

open access: yesArctic Science
Thinning sea ice cover and earlier melt in the Arctic impact primary producer (PP) phenology, causing earlier ice algal bloom termination and phytoplankton bloom commencement.

Identifying thermally tolerant bull kelp (Nereocystis luetkeana) source populations for restoration under climate change

open access: yesJournal of Phycology, EarlyView.
Abstract Kelp forests are declining in many parts of the world due to climate change and other stressors. Restoration is one solution to return kelp forests to places where they have been lost, yet continually warming oceans may necessitate the identification of thermally tolerant strains to facilitate the long‐term success of kelp restoration.

Eutrophication and ice phenology influence methane storage in north temperate lakes

open access: yesLimnology and Oceanography Letters
Among lakes, eutrophication is positively related to methane emissions, but various processes can alter the seasonal conversion of primary production into stored methane.

Phenotypic Differentiation Between Highland and Coastal Quinoa Under Cold Stress Conditions

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Quinoa (Chenopodium quinoa Willd.) is a genetically diverse Andean crop valued for its nutrition and adaptability to varied agro‐climatic conditions with potential for cultivation in European and Mediterranean, particularly on marginal lands. Low temperatures during early sowing can impair germination, while delayed sowing increases the risk ...

Early‐Season Warming Advances Autumn Senescence in Temperate Tree Saplings in Association With Early Growth Dynamics

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT The timing of autumn leaf senescence is driven by external cues such as temperature and photoperiod and is strongly regulated by internal developmental processes. Correlative evidence suggests that earlier budburst and warmer conditions in spring and summer could accelerate development and advance senescence, yet this hypothesis remains ...

Concurrent Increases in Root Phosphorus Acquisition and Leaf Phosphorus Resorption Underpin Enhanced Phosphorus Economy in Chickpea During Reproductive Development

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Phosphorus (P) acquisition and leaf P‐use strategies are critical for reproductive success and productivity, yet, their developmental association during the reproductive phase remains unclear. Five chickpea accessions contrasting in P‐remobilisation efficiency (PRE) were grown in a temperature‐controlled glasshouse under moderate P deficiency.

Unveiling contrasting iron efficiency strategies in common bean (Phaseolus vulgaris L.) genotypes under iron deficiency

open access: yesPlant Biology, EarlyView.
Common bean genotypes differ in their iron acquisition through distinct Strategy I responses and root exudation patterns. Abstract Iron (Fe) deficiency in food crops, particularly on calcareous soils, limits productivity and human nutrition. This study investigated two common bean (Phaseolus vulgaris) genotypes, Guaymí (high Fe‐accumulating, HI) and ...

Ice nucleation under cirrus cloud conditions [PDF]

open access: yes, 2012
Cirrus are thin upper tropospheric clouds that are composed entirely of ice particles. Due to their extensive coverage of the Earth’s surface, they have a significant impact on the Earth’s radiative balance.

The impact of seasonal variations in inner bark width and xylem growth on irreversible annual stem diameter measurements

open access: yesPlant Biology, EarlyView.
The seasonal variation in inner bark width differed from that of xylem growth, indicating that xylem phenology cannot be reliably assessed without cellular observations. Abstract To better interpret continuous xylem growth measurements from dendrometers, we evaluated how the widths of developing xylem and phloem, along with seasonal trends in inner ...
