Quantitative micro‐XRF combined with X‐ray imaging reveals correlations between Zn concentration and dentin tubule porosity across entire teeth

open access: yesVIEW, EarlyView.
The combination of calibrated micro‐CT and quantitative micro‐XRF measurement facilitates the correlation of density and composition in the 3D macro‐structure of teeth. Zn concentration in dentin increases by a factor of 10 toward the pulp. Incidentally, the overall density decreases, showing an association between Zn and the dentin tissue porosity ...

Tree cover and geographic origin of tree species drive bird functional groups in urban environments

open access: yesWildlife Biology, EarlyView.
Urban trees provide habitat and resources for wild species in cities and support biodiversity provision of ecosystem services, among which insect control is particularly relevant. Predators of insects are promoted by the presence of trees and, in turn, may enhance biosecurity of the trees.

Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

open access: yesWildlife Biology, EarlyView.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.

Risk factors for bark stripping damage on Norway spruce by red deer

open access: yesWildlife Biology, EarlyView.
Norway spruce Picea abies is an economically important tree species in Europe, actively managed for forestry. Among the most negative biotic factors for growth and hence forest production is damage caused by wildlife, such as damage through bark stripping by red deer Cervus elaphus.

Climbing the urban canopy: Camera trap insights into mammal activity and habitat use

open access: yesWildlife Society Bulletin, EarlyView.
Abstract Urbanization profoundly impacts wildlife behavior and habitat use. While the effects of urbanization on diel activity patterns and mammal interactions have been well studied at the ground level, little is known about spatiotemporal patterns above the ground.

Simultaneous Formation of Arsenic Nitride Chalcogenides As3NS3 and As3NSe3 and Arsenic–Chalcogen Zintl Anions by Ammonothermal Reactions

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Mn, As, and S or Se react in liquid NH3 to the Zintl ions (As4S6)2– and (As2Se6)2–. Simultaneously, the arsenic nitride chalcogenides As3NS3 and As3NSe3 are formed. Their isotypic structures contain planar trigonal NAs3 groups connected via chalcogen bridges to 1D‐strands forming channels that can host solvent molecules.

The Anionically All‐Boron‐Based Anti‐Perovskites Cs3[BH4][B12H12] and Cs3[BF4][B12H12]

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The anionically all‐boron‐based colorless anti‐perovskites Cs3[BH4][B12H12] and Cs3[BF4][B12H12] can be obtained by isothermal evaporation from aqueous solutions of the underlying pseudo‐binary components Cs2[B12H12] and Cs[BH4] or Cs[BF4]. At ambient conditions, Cs3[BH4][B12H12] crystallizes trigonally (R3¯$\overline{3}$m) and transforms reversibly ...

Compact tape‐driven sample delivery system for serial femtosecond crystallography

open access: yesJournal of Applied Crystallography, EarlyView.
A tape‐driven liquid sample droplet delivery system for serial femtosecond crystallography is described.We have developed a compact tape drive (CoT) with on‐demand sample delivery for time‐resolved serial femtosecond crystallography (SFX) experiments, which can deliver sample droplets and/or initiate reactions with a drop‐on‐drop strategy.
