Regional uniqueness of tree species composition and response to forest loss and climate change

Devis Tuia, Nina Marion Aurélia Van Tiel

The conservation and restoration of forest ecosystems require detailed knowledge of the native plant compositions. Here, we map global forest tree composition and assess the impacts of historical forest cover loss and climate change on trees. The global oc ...

Generation and application of river network analogues for use in ecology and evolution

Andrea Rinaldo, Enrico Bertuzzo, Luca Carraro, Reinhard Furrer, Florian Altermatt

Several key processes in freshwater ecology are governed by the connectivity inherent to dendritic river networks. These have extensively been analyzed from a geomorphological and hydrological viewpoint, yet structures classically used in ecological modeli ...

Plant responses to rising vapor pressure deficit

Charlotte Grossiord

Recent decades have been characterized by increasing temperatures worldwide, resulting in an exponential climb in vapor pressure deficit (VPD). VPD has been identified as an increasingly important driver of plant functioning in terrestrial biomes including ...

Global radiation in a rare biosphere soil diatom

Tyler Joe Kohler

Soil micro-organisms drive the global carbon and nutrient cycles that underlie essential ecosystem functions. Yet, we are only beginning to grasp the drivers of terrestrial microbial diversity and biogeography, which presents a substantial barrier to under ...

Variation in Detrital Resource Stoichiometry Signals Differential Carbon to Nutrient Limitation for Stream Consumers Across Biomes

Janine Rüegg

Stoichiometric ratios of resources and consumers have been used to predict nutrient limitation across diverse terrestrial and aquatic ecosystems. In forested headwater streams, coarse and fine benthic organic matter (CBOM, FBOM) are primary basal resources ...

A two-layer canopy model with thermal inertia for an improved snowpack energy balance below needleleaf forest (model SNOWPACK, version 3.2.1, revision 741)

Michael Lehning, Isabelle Amandine Gouttevin

A new, two-layer canopy module with thermal inertia as part of the detailed snow model SNOWPACK (version 3.2.1) is presented and evaluated. As a by-product of these new developments, an exhaustive description of the canopy module of the SNOWPACK model is p ...

The mid-Holocene vegetation of the Mediterranean region and southern Europe, and comparison with the present day

Jed Oliver Kaplan, Basil Andrew Stansfield Davis, Pamela Collins

Aim To contribute to the intense debate surrounding the relative influence of climate and humans on Mediterranean-region land cover over the past 6000 years, we assess the Holocene biogeography and vegetation history of southern Europe by means of an exten ...

Isotopic analysis of cyanobacterial nitrogen fixation associated with subarctic lichen and bryophyte species

Konstantin Svetlozarov Gavazov

Dinitrogen fixation by cyanobacteria is of particular importance for the nutrient economy of cold biomes, constituting the main pathway for new N supplies to tundra ecosystems. It is prevalent in cyanobacterial colonies on bryophytes and in obligate associ ...

Multidisciplinary approach to reconstructing local pastoral activities: an example from the Pyrenean Mountains (Pays Basqueq)

Alexandre Buttler

In this study archaeology, history and palaeoecology (modern and fossil data sets of pollen and non-pollen palynomorphs) were used to reconstruct small-scale pastoral activities in the Pyrenees Mountain during the last two millennia. Modern pollen assembla ...

Variations in leaf area index in northern and eastern North America over the past 21,000 years: a data-model comparison

Jed Oliver Kaplan

Over the past 10 years, there has been a growing debate about the relative importance of late-Quaternary variations in climate and CO2 as drivers of changes in vegetation structure. In this study, we compare new datasets of pollen-reconstructed leaf area i ...

Simulating future changes in Arctic and subarctic vegetation

Jed Oliver Kaplan

The Arctic is a sensitive system undergoing dramatic changes related to recent warming trends. Vegetation dynamics-increases in the quantity of green vegetation and a northward migration of trees into the arctic tundra-are a component of this change. Altho ...
