Barley Straw (Hordeum vulgare) as a Supplementary Raw Material for Eucalyptus camaldulensis and Pinus sylvestris Kraft Pulp in the Paper Industry

open access: yesBioResources, 2015
The present study shows that barley straw (Hordeum vulgare) can be a supplementary raw material of softwoods and hardwoods such as Pinus sylvestris and Eucalyptus camaldulensis, respectively, for the production of cellulose and paper, reducing an ...

Fragmented grasslands in different landscape structures provide different opportunities for cavity‐nesting Hymenoptera

open access: yesInsect Conservation and Diversity, EarlyView.
Grassland fragmentation effects on cavity‐nesting Hymenoptera are habitat‐specific. Isolated sand steppe fragments are associated with higher brood‐cell abundance. In loess steppes, higher flower frequency increases bee brood‐cell production and parasitoid activity. Abstract The global decline in insects threatens ecosystem functioning, but the drivers

Identification of gene pools used in restoration and conservation by chloroplast microsatellite markers in Iberian pine species

open access: yesForest Systems, 2017
Aim of study: To contribute to the characterization of the origin of material used in afforestation, restoration or conservation activities by using Cp-SSR markers. Area of study: We used information from the natural range of Iberian pines, from Spain.

Mapping wild bee diversity and flower use for an effective conservation of the Doñana biodiversity hotspot

open access: yesInsect Conservation and Diversity, EarlyView.
We compiled the first checklist of wild bees in Doñana Protected Area, documenting 385 species, including three vulnerable and one endangered species listed in the Red List. Bee species exhibit diverse floral preferences, highlighting the need to incorporate plant–pollinator interactions and the role of plants in conservation and management strategies ...

Species‐level controls of foliar methane and nitrous oxide fluxes: roles of traits and microbes in temperate trees

open access: yesNew Phytologist, EarlyView.
Species‐level variation in temperate tree foliar greenhouse gas exchange, showing consistent foliar CH4 uptake, N2O emission, stronger CH4 uptake in fall leaves, and contrasting methanotroph communities between the high‐CH4‐oxidizing species Tilia americana and the low‐CH4‐oxidizing species Prunus virginiana. Summary The contribution of tree foliage to

Stand structure and spatial pattern of regeneration of Pinus sylvestris in a natural treed mire in Latvia

open access: yesSilva Fennica, 2009
We examined the regeneration patterns of Pinus sylvestris L. in a natural treed mire in the hemiboreal zone in Latvia. Data on tree stem age and size was collected in 207 fine-scale plots (10 m) and 4 medium-scale plots (400 m).

Ectomycorrhizal Cortinariaceae species dominate class II peroxidase gene expression in a boreal forest soil

open access: yesNew Phytologist, EarlyView.
Share of transcripts and ITS2 sequence for each gene families among identified fungal contigs and OTUs. Summary Boreal forest ecosystems constitute a large terrestrial reservoir of carbon. In these nitrogen‐limited environments, release of nutrients through decomposition of soil organic matter is of fundamental importance.

Evolutionary Conserved and Divergent Responses to Copper Zinc Superoxide Dismutase Inhibition in Plants

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT After an initial evolution in a reducing environment, life got successively challenged by reactive oxygen species (ROS), especially during the great oxidation event (GOE) that followed the development of photosynthesis. Therefore, ROS are deeply intertwined into the physiological, morphological and transcriptional responses of most present‐day

Disentangling Thermal and Hydraulic Drivers of Stomatal Conductance Under Hot Versus Dry Vapour Pressure Deficit Increases Using Water‐Use Efficiency

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Predicting plant functioning in a warming world requires capturing its divergent responses to hot versus dry vapour pressure deficit (VPD) increases. Stomatal responses to VPD are typically studied without disentangling the effects of RH and temperature, creating uncertainties for future plant functioning.

Thermotolerance thresholds of the photosystem II increase with elevation in conifer species in the Spanish Pyrenees

open access: yesPlant Biology, EarlyView.
In vitro‐tested photosystem II thermotolerance of seven temperate conifers indicated higher thermal thresholds in species growing in high elevations compared to those in the lowlands. Higher thermotolerance might be explained by the adaptation of species in higher elevations to extreme diurnal temperature fluctuations.
