Corrigendum to “Pollen-based paleoenvironmental and paleoclimatic change at Lake Ohrid (south-eastern Europe) during the past 500 ka” published in Biogeosciences, 13, 1423–1437, 2016 [PDF]

, 2018
In this corrigendum we report an updated pollen record from the Lake Ohrid DEEP site spanning the past 500 ka whereby we have reprocessed and re-analyzed 104 samples affected by chemical procedure problems that occurred in one palynological laboratory ...

Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks trait and classification modeling in plant biodiversity collections

New Phytologist, EarlyView.
Summary Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof‐of‐concept study using trait data and spectra from herbarium specimens up to 179 yr old,

Shaping future forests: how can ecophysiology support climate‐smart forest management?

New Phytologist, EarlyView.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

A Mariotte-based verification system for heat-based sap flow sensors [PDF]

, 2012
Determination of the accuracy of commonly used techniques for measuring sap flux density in trees often presents a challenge. We therefore designed and built a verification system for heat-based sap flow sensors typically used at stem level.

Equipped for success: genomes and metabolomes of the European Amanita muscaria are conserved in its novel South African range

New Phytologist, EarlyView.
Summary Plants and soils have been moved around the world for centuries, but invasive mushrooms receive scant attention. The Amanita muscaria species complex was introduced to South Africa in the context of forestry, but its origins, ecology and recent evolution are unstudied. We sequenced the genomes of 24 Northern and Southern Hemisphere A. muscaria,

Classification and Protection Status of Remnant Natural Plant Communities in Arkansas [PDF]

, 1981
A classification and inventory of Arkansas\u27s remaining tracts of relatively undisturbed vegetation was initiated in 1979. Based on extensive literature surveys and field work, the classification includes five physiognomic classes, 17 cover classes ...

Effect of a major ice storm on understory light conditions in an old-growth Acer-Fagus forest: Pattern of recovery over seven years [PDF]

, 2007
We evaluated the effects of a major ice storm on understory light conditions (%PPFD, photosynthetic photon flux density) in an old-growth Acer-Fagus forest in Quebec, based on pre- and post-disturbance light measurements taken until the seventh growing ...

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

Plant, Cell &Environment, EarlyView.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...

Factors determining the occurrence of Flat Bugs (Aradidae) in beech dominated forests [PDF]

, 2007
The habitat requirements of most Aradidae and the decisive factors that influence their occurrence are still poorly understood. To reduce this lack of knowledge a standardised survey of Aradidae in two large beech forest areas of Bavaria (northern ...

Similar Relative Carbon Costs for Construction and Storage of Sun and Shade Branches in Mature Temperate Trees

Plant, Cell &Environment, EarlyView.
ABSTRACT Irradiance strongly affects the morphology, carbon (C) uptake and construction costs of leaves and branches. Within tree crowns, light decreases from the top downwards, but whether this translates to differences in the C balance of sun and shade branches remains unclear. Here, we combined a light‐driven photosynthesis model, parameterised with
