Humans modify ecosystems and biodiversity worldwide, with negative consequences for ecosystem functioning. Promoting plant diversity is increasingly suggested as a mitigation strategy. However, our mechanistic understanding of how affects the heterotrophic consumer communities remains limited. Here, we disentangle relative importance key components drivers herbivore, predator, parasitoid species richness in experimental forests grasslands. We find that effects on are consistently positive...

Tree species diversity and mycorrhizal associations play a central role for forest productivity, but factors driving positive biodiversity-productivity relationships remain poorly understood. In biodiversity experiment manipulating tree associations, we examined the roles of above- belowground processes in modulating wood productivity young temperate communities potential underlying mechanisms. We found that richness, not increased by enhancing aboveground structural complexity within...

Theory suggests that plant interactions at the neighbourhood scale play a fundamental role in regulating biodiversity-productivity relationships (BPRs) tree communities. However, empirical evidence of this prediction is rare, as little known about how up to influence community BPRs. Here, using biodiversity-ecosystem functioning experiment, we provide insights into processes underlying BPRs by demonstrating diversity-mediated among local neighbours are strong regulator productivity species...

Abstract There is increasing evidence that mixed‐species forests can provide multiple ecosystem services at a higher level than their monospecific counterparts. However, most studies concerning tree diversity and functioning relationships use data from forest inventories (under noncontrolled conditions) or very young plantation experiments. Here, we investigated temporal dynamics of diversity–productivity diversity–stability in the oldest tropical experiment. Sardinilla was established...

Abstract Biodiversity is considered to mitigate detrimental impacts of climate change on the functioning forest ecosystems, such as drought‐induced decline in productivity. However, previous studies produced controversial results and experimental evidence rare. Specifically, biological mechanisms underlying mitigation effects remain unclear, existing work focuses biodiversity related community scale. Using trait‐based neighbourhood models, we quantified changes above‐ground wood productivity...

ABSTRACT Question The order of arrival plant species during community assembly can affect how interact with each other. These so‐called priority effects have strong implications for the structure and functioning communities. However, extent to which strength, direction, persistence are modulated by weather conditions establishment (“year effects”) is not well known. Location Niederhaverbeck, Bispingen, Germany. Methods We present first results from a field experiment initiated in 2020...

Variations in crown forms promote canopy space-use and productivity mixed-species forests. However, we have a limited understanding on how this response is mediated by changes within-tree biomass allocation. Here, explored the role of tree allometry, allocation architecture shaping diversity-productivity relationships (DPRs) oldest tropical diversity experiment. We conducted whole-tree destructive measurements terrestrial laser scanning. Spatially explicit models were built at level to...

Intensification of land use by humans has led to a homogenization landscapes and decreasing resilience ecosystems globally due loss biodiversity, including the majority forests. Biodiversity-ecosystem functioning (BEF) research provided compelling evidence for positive effect biodiversity on ecosystem functions services at local (α-diversity) scale, but we largely lack empirical how between-patch β-diversity affects multifunctionality landscape scale (γ-diversity). Here, present novel...

Understanding how trees respond to global change drivers is central predict changes in forest structure and functions. Although there evidence on the mode of nitrogen (N) drought (D) effects tree growth, our understanding interplay these factors still limited. Simultaneously, as mixtures are expected be less sensitive compared monocultures, we aimed investigate combined N addition D productivity three species (Fagus sylvatica, Quercus petraea, Pseudotsuga menziesii) relation functional...

Abstract Herbivores and fungal pathogens are key drivers of plant community composition functioning. The effects herbivores mediated by the diversity functional characteristics their host plants. However, combined herbivory pathogen damage, consequences for performance, have not yet been addressed in context biodiversity–ecosystem functioning research. We analyzed relationships between herbivory, damage on tree growth a large‐scale forest‐biodiversity experiment. Moreover, we tested whether...

Abstract Forest structural complexity has been identified as an important driver for promoting simultaneously biodiversity across trophic levels and multiple ecosystem services. However, we still have a limited understanding of the processes that lead to complex stands how they evolve over time. Using terrestrial laser scanning (TLS), quantified three‐dimensional (3D) stand index (SSCI) in experimental plantation with long gradient tree species richness (1–24 species). The was established...

Abstract Biodiversity–ecosystem functioning (BEF) research has provided strong evidence and mechanistic underpinnings to support positive effects of biodiversity on ecosystem functioning, from single multiple functions. This knowledge gained mainly at the local alpha scale (i.e. within ecosystems), but increasing homogenization landscapes in Anthropocene raised potential that declining beta (across ecosystems) gamma scales is likely also impact functioning. Drawing theory, we propose a new...

Abstract The relationship between biodiversity and multitrophic ecosystem functions (BEF) remains poorly studied in forests. There have been inconsistent reports regarding the significance of tree diversity effects on functions, which may be better understood by considering critical biotic interactions trees. This study investigates role tree‐mycorrhizal associations that shape forest BEF relationships across multiple functions. We used a field experiment (MyDiv) comprises 10 deciduous...

Earthquake sequences in region are clustered along fault, yet local earthquake catalog records remain sparse.From April 23 to June 22, 2024, we conducted two-month Distributed Acoustic Sensing (DAS) experiment on Island using 15 km dark fiber network—7 roadway 8 across seafloor.
