Across the forested Finnish landscapes, we looked at which mechanisms structure breeding bird communities, between energy, landscape heterogeneity, and habitat amount. We surprisingly found more functionally diverse and specialized communities northwards. Check for more here 👇 🧪🌐🍁

Long overdue, but the main results of my metacommunity experiment are finally out! Different aspects of spatial network structure shape ecological dynamics at different scales—connectivity boosts biomass overall, but locally it can do the opposite. 🔬🧫🌐

Fascinating new insights on the forest volatilome! 🍁🧪 Led by Lena Carlson we identify deadwood as a main driver of VOC beta-diversity, linked to the diversity of beetles. 🪲 @betafor.bsky.social @ecoresearchzoo3.bsky.social
The invisible heterogeneity of forests—β-diversity of volatiles - Landscape Ecology
Context Volatile organic compounds (VOCs) create invisible chemical landscapes that influence ecosystem processes. Yet whether VOC β-diversity (i.e., variability in VOC composition between patches) responds to structural heterogeneity and reflects silvicultural habitat management remains unclear. Objectives In a large field experiment, we quantified how enhanced structural beta complexity (ESBC) affects VOC β-diversity patterns and investigated potential drivers and ecological effects in temperate production forests. Methods We sampled VOCs in ambient forest air using Tenax/Carboxen adsorbent traps at forest floor and 1 m heights across 234 treatment and control forest patches in six German regions. We analyzed VOCs via thermal desorption-gas chromatography mass-spectrometry (TD-GCMS) and examined environmental drivers including deadwood characteristics, canopy cover, tree species dissimilarity, and herb layer dissimilarity. We tested potential ecological relevance by analyzing saproxylic beetle community responses. Results VOC β-diversity increased significantly at 1 m height in heterogeneous forests compared to homogeneous forests, but we found no significant change at the forest floor. Deadwood volume and deadwood structural diversity, rather than canopy openness, were identified as the main drivers of increasing VOC β-diversity. Dissimilarity in beetle community composition was associated with VOC β-diversity, but only for forest floor VOCs, suggesting these chemical patterns may correlate with variables beetles respond to. Conclusions Our findings suggest that volatile β-diversity represents an overlooked dimension of habitat heterogeneity, one that creates invisible chemical heterogeneity influencing inter- and intra-species interactions and ecosystem processes. We demonstrate that enhancing forest heterogeneity through deadwood retention increases both structural heterogeneity and volatile β-diversity.

Nonnative forestry plantations: invasion epicenters?
Nonnative plantations offer economic benefits but increase the risk of biological invasions worldwide. This risk is primarily driven by frequent anthropogenic disturbances and autocatalytic processes that can lead to an invasion meltdown, creating hotspots that amplify ecological impacts. This underscores the urgent need to balance economic benefits with ecosystem sustainability.
