Molecular investigation of the phylogenetic placement of Kartalinia and a revision of Bituminaria (Fabaceae: Psoraleeae)

open access: yesTAXON, Volume 75, Issue 4, August 2026.
Abstract The genus Kartalinia was described to accommodate a single, obscure species, Psoralea acaulis, based on its unique morphology and karyology. No concerted molecular phylogenetic studies were available for this species at the time, and therefore its phylogenetic position was uncertain.

Fluorescence-Detected Linear Dichroism of Wood Cell Walls in Juvenile Serbian Spruce: Estimation of Compression Wood Severity [PDF]

open access: yesMicroscopy and Microanalysis, 2016
AbstractFluorescence-detected linear dichroism (FDLD) microscopy provides observation of structural order in a microscopic sample and its expression in numerical terms, enabling both quantitative and qualitative comparison among different samples. We applied FDLD microscopy to compare the distribution and alignment of cellulose fibrils in cell walls of

The liverwort genus Metzgeria (Jungermanniopsida) in Europe – An integrative taxonomic update

open access: yesTAXON, Volume 75, Issue 3, June 2026.
Abstract Species delimitation in liverworts, such as Metzgeria, is hampered by their limited morphology and hence morphologically determined specimens often turn out to belong to other taxa using molecular data. Metzgeria is a simple thalloid liverwort genus with over 100 species and a worldwide distribution. Seven species are listed to occur in Europe.

Bioclimatic, demographic and anthropogenic correlates of grizzly bear activity patterns in the Greater Yellowstone Ecosystem

open access: yesOikos, Volume 2026, Issue 4, April 2026.
Plasticity of diel activity rhythms may be a key element for adaptations of wildlife populations to changing environmental conditions. In the last decades, grizzly bears Ursus arctos in the Greater Yellowstone Ecosystem (GYE) have experienced notable environmental fluctuations, including changes in availability of food sources and severe droughts ...

A Generic Spinup Procedure to Initialize European Forest State Variables in Land Surface Models

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 4, April 2026.
Abstract Forest structure is shaped by forest management practices, land‐use changes, and natural disturbances, including droughts, fires, storms, and insect outbreaks that drive species‐specific and size‐specific mortality. By modifying the carbon‐water‐energy exchanges with the atmosphere, it influences a stand's capacity to buffer against or succumb

Mycochemical Diversity and Therapeutic Potential of Hymenochaetoid Fungi from Central Asia: Regional and Global Perspectives

open access: yesNew Zealand Journal of Botany, Volume 64, Issue 1, March 2026.
Central Asia harbors a rich yet understudied assemblage of wood‐inhabiting Hymenochaetoid fungi. This review delivers the first comprehensive synthesis of 43 poroid species representing 18 genera documented across montane forests, steppes, and xeric habitats.

The effect of pH on the activity of soluble peroxidase in needles of Serbian spruce (Picea omorika (Panč.) Purkinye): application of a mathematical model [PDF]

open access: yesGeneral Physiology and Biophysics, 2010
We studied the dependence of peroxidase (POD) activity on pH in crude extract of Picea omorika (Panc.) Purkinye needles and in its acidic and basic fractions, obtained by ion exchange chromatography. Nonlinear regression was applied on the activity data with pH as the explaining variable, using the Levenberg-Marquardt algorithm.

A graduated nativeness definition for overcoming dilemmas and difficulties of vascular plant species

open access: yesOikos, Volume 2026, Issue 2, February 2026.
Nativeness is a concept central to biodiversity conservation and invasion biology, but there are several problems related to a classic binary nativeness definition. Dilemmas arise from the dynamic nature of species' distribution ranges on longer time scales, and difficulties arise in the application to smaller regions defined by arbitrary borders, and ...

Prilog poznavanju zemljišta u prirodnim sastojinama omorike

open access: yesGlasnik Šumarskog Fakulteta Univerziteta u Banjoj Luci
U radu su prikazani rezultati pedoloških istraživanja u sastojinama Pančićeve omorike (Picea omorika /Panč./Purkyne) zahvaćenih požarima i dijelovi koji nisu opožareni, kao i drugih tretmana primjenjenih u projektu Franklinia (2021–2023).

Experimental enhancement of structural heterogeneity in forest landscapes promotes multidimensional hoverfly diversity

open access: yesJournal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our results provide the first experimental evidence that enhancing structural heterogeneity at the landscape scale can restore multidimensional hoverfly diversity in temperate forests. They underscore the management value of ESBC as a scalable tool to restore biodiversity, increase ecological resilience and counteract biotic homogenization in ...
