Automated extraction of leaf mass per area from digitized herbarium specimens

open access: yesNew Phytologist, EarlyView.
Summary The digitization of vast herbarium collections has made millions of plant specimen images freely available online, which can now be used to generate phenotypic datasets of unprecedented scope. Here, we assess the potential of computer vision tools to automate the extraction of predicted leaf mass per area (LMApred) from digitized herbarium ...

Ground beetles (Coleoptera: Carabidae) as predators of conifer seeds

open access: yesFolia Oecologica, 2019
Many species of ground beetles (Coleoptera: Carabidae) are important predators of seeds. While the consumption of herb seeds has been intensively studied, little attention has been paid to the consumption of seeds of gymnosperm plants.

The viscoelastic properties of some Guianese woods [PDF]

open access: yes, 2009
Samples of tension wood and opposite wood were obtained from four species (#Iyranthera sagotiana#, #Ocotea guyanensis#, #Virola micheli#i, #Sextonia rubra#) growing in the tropical rainforest of French Guiana. Dynamic mechanical analysis was performed in

Ecological and genomic variation in ectomycorrhizal fungal exploration types

open access: yesNew Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EMF) produce mycelia with variable extension and complexity, which can be classified according to soil ‘exploration types’ (ETs). ETs have received attention as one of the few mycorrhizal trait frameworks, but without an empirical classification of ET functional diversity and environmental preferences, understanding and ...

Radial variation of tracheid features, specic gravity and growth rings in Araucaria angustifolia (Bertol.) Kuntze planted in Cunha-SP. Variação radial das características das traqueídes, densidade aparente e anéis de crescimento em Araucaria angustifolia (Bertol.) Kuntze plantadas em Cunha-SP. [PDF]

open access: yesRevista do Instituto Florestal, 2015
We investigated wood features along growth rings of Araucaria angustifolia trees planted between November and December of 1980 in Parque Estadual da Serra do Mar in Cunha, State of São Paulo, Brazil.

Environmental and climatic proxies for the Cañadón Asfalto and Neuquén basins (Patagonia, Argentina): review of middle to upper jurassic continental and near coastal sequences [PDF]

open access: yes, 2015
In this review, we include several proxies (sedimentology, palynology, invertebrates) from the Cañadón Asfalto and Neuquén basins, to infer the environments and regional climatic context during the Middle to Late Jurassic of Patagonia.

Tree‐ring structure determines the temporal coordination between xylem growth and the gain in hydraulic conductivity in the outermost ring

open access: yesNew Phytologist, EarlyView.
Summary The study of seasonal xylem hydraulics has predominantly focused on embolism‐induced losses, whereas growth‐driven increases in hydraulic capacity have received little attention. We assessed the intra‐annual dynamics of xylem formation and gain of conductivity in the current‐year ring of three species with contrasting tree‐ring structure ...

Development of a Target Enrichment Probe Set for Conifer (REMcon)

open access: yesBiology
Conifers are an ecologically and economically important seed plant group that can provide significant insights into the evolution of land plants. Molecular phylogenetics has developed as an important approach in evolutionary studies, although there have ...
