Abstract Context Humans have drastically changed many of the world’s forests since industrial revolution, with northern European among most affected. Research is needed on consequent effects forest biodiversity. Here I focus conservation-relevant wood-living beetles. Whilst previous studies examined effect local stand characteristics beetle diversity, influence surrounding landscape alpha diversity may potentially be more important. Objectives The aim this study to judge and scale four variables (broadleaf volume, area mature forest, conservation clear-cut) beetles as a whole, ecological groups reflecting differing dispersal ecologies (fungivores, wood consumers, predators, red-listed species). Methods were analyzed at three scales (within 250, 1250 2500 m radius) related sampled using flight interception traps in 73 managed unmanaged stands conifer forestry dominated hemiboreal south-central Sweden.

Conclusions results highlight importance trees saproxylic conifer-dominated landscapes. Further, research management should closely consider contrasting responses between species ecologies, different scales.

The quantification of tree-related microhabitats (TreMs) and multi-taxon biodiversity is pivotal to the implementation forest conservation policies, which are crucial under current climate change scenarios. We assessed capacity Airborne Laser Scanning (ALS) data quantify indices related both beetle bird communities TreMs, calculating species richness types saproxylic epixylic TreMs using Shannon index. As predictors, 240 ALS-derived metrics were calculated: 214 point-cloud based, 14 pixel-level from canopy height model, 12 RGB spectral statistics. used random forests algorithm predict diversity index, field plot measures as dependent variables predictors for each taxon type. final models produce wall-to-wall maps indices. index produced best performance group considered, with a mean difference −6.7%. Likewise, highest R2 was (0.17, against 0.14 richness). Our results confirm importance ALS in assessing indicators that relevant monitoring habitats. proposed method supports needed implement better stands conservation.

This study investigates the impact of elevated temperatures on arthropod communities in intensively managed pastures volcanic island Terceira, Azores (Portugal), using a functional trait approach. Open Top Chambers (OTCs) were employed to simulate increased temperatures, and traits ground dwelling arthropods analyzed along small elevation gradient (180–400 m) during winter summer. Key findings include lower abundances herbivores, coprophagous organisms, detritivores, fungivores at high elevations summer, with predators showing peak middle elevations. Larger-bodied more prevalent higher winter, while beetles exhibited distinct ecological traits, larger species peaking The OTCs significantly affected communities, increasing abundance predators, by alleviating environmental stressors. Notably, iridescent decreased common inside elevations, suggesting thermoregulatory advantage. underscores importance considering assessing impacts climate change highlights complex, species-specific nature their responses changes.
