Phylogeny, species delimitation and machine learning bridge the gap between DNA sequences and morphology in the lichen genus Arctomia (Arctomiaceae, Ascomycota)

open access: yesTAXON, EarlyView.
Abstract This study investigates species boundaries in the lichen genus Arctomia (Arctomiaceae, Ascomycota) using an integrative approach combining molecular phylogenetics, full Bayesian population delimitation, heuristic and model‐based species delimitation, and supervised machine learning applied to morphological data.

Modern Abies, Picea, and Tsuga pollen distribution along the elevation gradient in East Asia

open access: yesGlobal Ecology and Conservation
Sub-alpine dark coniferous forests (SCFs) exhibit distinct latitudinal and longitudinal elevation distributions in East Asia. The SCF genera Abies, Picea, and Tsuga produce distinctive pollen and have specific elevation and climate requirements, allowing

Effects of Pyrolysis Control Parameters on the Structural Properties of Biomass‐Derived Activated Carbon Materials and Their Energy Applications

open access: yesThe Chemical Record, EarlyView.
Tubular pyrolysis synthesis is a widespread method to produce activated carbons (ACs). This review focuses on the different controlling parameters of the tubular pyrolysis synthesis method and their influence on the performance of synthesized ACs, thereby considering both experimental aspects and the use of plant‐based biomasses (PBBs) as feedstock ...

Comparative leaf anatomy of some species of Abies and Picea (Pinaceae)

open access: yesActa Botânica Brasílica, 2015
A number of conifer species are still lacking anatomical data, which is significant because morphological and anatomical data are essential for systematic study.

Growth allocation and stand structure in Norway spruce stands [PDF]

open access: yes, 2005
This thesis is based on analyses of permanent sample plot data gathered over periods of 10-34 years from an experiment in which a wide range of thinning regimes, and thinnings combined with N-fertilisation, were applied to 25 even-aged Norway spruce ...

Monitoring GPS‐collared moose by ground versus drone approaches: efficiency and disturbance effects

open access: yesWildlife Biology, EarlyView.
Efficient wildlife management requires precise monitoring methods, for example to estimate population density, reproductive success, and survival. Here, we compared the efficiency of drone (equipped with a RGB camera) and ground approaches to detect and observe GPS‐collared female moose Alces alces and their calves. We also quantified how drone (n = 42)

Pollen frequency of Abies and Picea in peat: A correction on some published records from Indiana bogs and lakes [PDF]

open access: yes, 1944
An error was introduced in a number of reports on pollen profiles from Indiana bogs and lakes because Picea and Abies were separated on basis of size as presented in a key by Sears, which included only Picea mariana but not Picea ...
