Influence of Deadwood, Tree‐Related Microhabitats, and Forest Structural Features on Saproxylic Arthropod Diversity

Ecology and Evolution, Volume 16, Issue 5, May 2026.
We used environmental DNA (eDNA) metabarcoding across 135 temperate forest plots in Germany to examine how deadwood, tree‐related microhabitats (TreMs), and forest structure shape saproxylic arthropod communities. Structural equation modeling revealed that TreM richness and deadwood volume are key predictors of arthropod diversity, highlighting the ...

X-ray based tree ring analyses [PDF]

, 2004
In this thesis, two x-ray based dendro-analyses (batch-wise microdensitometry and energy dispersive x-ray fluorescence (EDXRF)) and the conditions under which these methods could be used on the two typical boreal conifers Norway spruce (Picea abies (L ...

Differences in Phenological Estimation From Multi‐Vegetation Indices Across the Yellow River Basin

Ecology and Evolution, Volume 16, Issue 5, May 2026.
This study evaluated the differential performance of PPI, kNDVI, and EVI in monitoring land surface phenology across the Yellow River Basin. The three vegetation indices showed pronounced divergence in capturing autumn phenological metrics, particularly the downturn date (DD) and recession date (RD).

Incomplete but Useful? Professional Responses to Cost‐Containment Constructs

Financial Accountability &Management, Volume 42, Issue 2, Page 261-275, May 2026.
ABSTRACT Adopting an institutional logics lens, this study examines how different professional groups interpret and respond to incompleteness during the development of an accounting construct in a U.S. teaching hospital. Using an interventionist research design, we co‐developed the construct by integrating financial and clinical data to identify and ...

A Review of a Decade of Anadromous Salmonid Hatchery (And Stocking) Research: Insights for Policy, Management and a Changing Climate

Fish and Fisheries, Volume 27, Issue 3, Page 431-450, May 2026.
ABSTRACT Hatcheries and stocking programmes have long been a cornerstone of fisheries management, seen as tools for fisheries enhancement and/or conservation of threatened populations. Their use draws controversy, however, from a growing body of research over the last 50 years suggesting that stocking can have negative consequences for wild stocks, and

Atomistic simulations of rare events using gentlest ascent dynamics

, 2011
The dynamics of complex systems often involve thermally activated barrier crossing events that allow these systems to move from one basin of attraction on the high dimensional energy surface to another.

Biogeographical Regionalisation of Southern Africa Using Tenebrionid Beetles: A Multi‐Scale Analysis of Diversity and Environmental Drivers

Journal of Biogeography, Volume 53, Issue 5, May 2026.
ABSTRACT Aim Southern Africa's remarkable environmental heterogeneity drives high biodiversity and endemism, yet biogeographical regionalisations often overlook invertebrates despite their ecological significance. This study presents a comprehensive regionalisation of southern Africa using tenebrionid beetles (Coleoptera: Tenebrionidae), a diverse and ...
