Global homeostatic forces shape the composition of a hyperdiverse tropical insect fauna

The paper estimates Madagascar's insect fauna contains at least 250,000 species, most unrecorded, and finds global homeostatic forces, not lineage composition, shape its ecological similarity to temperate forests.

Biotic and abiotic drivers of ecosystem functioning differ between a temperate and a tropical region

This study compares biotic and abiotic drivers of ecosystem functioning in temperate and tropical regions, finding differing patterns and drivers between the two zones.

Climate structures global associations between human footprint and arthropod diversity

The paper introduces Hubbell regression to estimate biodiversity descriptors and finds actual evapotranspiration is the largest predictor of arthropod diversity, with human activity reducing insect richness in tropical and dry zones.

Is there a fly in my soup? To what extent do metabarcoding and individual barcoding tell the same story?

This study compares metabarcoding and individual barcoding of insect samples, finding they yield similar community structure but metabarcoding adds more species due to DNA residues.

Discovering the unseen: a performance comparison of taxonomic classification methods under unknown DNA barcodes

This study compares taxonomic classification methods for DNA barcoding, finding that phylogenetic placement methods excel for arthropod COI barcodes while composition-based classifiers perform better for fungal ITS.

Accuracy of occurrence and abundance estimates from insect metabarcoding

This study evaluates how lysis methods, spike-ins, and sample processing affect the accuracy of insect metabarcoding for species occurrence and abundance.

Malaise trap samples of 1000 individuals per week suggest 4 million insects per hectare in the boreal zone

The paper estimates insect density in boreal forests using a mark-recapture experiment with Malaise traps, finding 4 million individuals per hectare.

Habitat context alters the pace of climate-driven community warming across terrestrial and freshwater ecosystems

The paper shows habitat structure influences the rate of community warming in response to climate change across different ecosystems.

Inferences about phenological shifts in an Arctic community vary with time-windows

This study shows that phenological shifts in an Arctic community vary with time-windows, revealing moderate warming trends and species-specific responses.

HAPP: High-Accuracy Pipeline for Processing deep metabarcoding data

HAPP improves deep metabarcoding data processing by enhancing signal-to-noise ratio through four steps, showing significant performance improvements over existing methods.

Experimental community ecology in decline: A call to embrace technology

This paper reviews experimental community ecology research, highlights gaps in taxa and scale, and proposes integrating high-throughput technologies to improve experimental scope and efficiency.

Common to rare transfer learning (CORAL) enables inference and prediction for a quarter million rare Malagasy arthropods

The paper introduces CORAL, a transfer learning method that improves prediction and inference for rare species using DNA metabarcoding data from Madagascar.

What lurks in the dark? - An innovative framework for studying diverse wild insect microbiota

This study uses a novel multi-target amplicon sequencing approach to analyze microbiota in wild scuttle flies, revealing significant variation in bacterial abundance and composition across host species and genotypes.

Opportunistic partner choice among arctic plants and root-associated fungi is driven by environmental conditions.

The paper investigates how environmental factors shape plant-fungus interactions in Arctic ecosystems, finding that fungal communities in soil and rhizosphere differ significantly and are primarily driven by abiotic conditions.

Harmonising digitised herbarium data to enhance biodiversity knowledge: creating an updated checklist for the flora of Greenland.

This paper presents a workflow to harmonize digitized herbarium data, resulting in a more accurate checklist of Greenland's flora with increased species richness and occurrence records.

Data of the Insect Biome Atlas: a metabarcoding survey of the terrestrial arthropods of Sweden and Madagascar

The paper presents comprehensive DNA metabarcoding data from Sweden and Madagascar, characterizing terrestrial arthropod faunas and providing insights into community composition and dynamics.

The environmental dependence of ecological interactionnetworks

This paper shows that species and link occurrences in ecological networks are stochastic and conditional on environmental factors, improving network modeling by integrating Grinnellian and Eltonian niche concepts.

High-throughput biodiversity surveying sheds new light on the brightest of insect taxa

One year of COI metabarcoding of 197 Malaise traps across Sweden detected 1,535 of 2,990 known Lepidoptera species, plus specimen-validated new country records, range extensions and putative undescribed species.

RESOLVING BIOLOGY'S DARK MATTER: SPECIES RICHNESS, SPATIOTEMPORAL DISTRIBUTION, AND COMMUNITY COMPOSITION OF A DARK TAXON

The paper uses DNA barcoding to study scuttle flies in Sweden, revealing high diversity and showing that climate factors strongly influence their distribution.

Cold and lonely: low microbial abundance and no core microbiota in mosquito populations across Greenland

The paper analyzes microbial communities in Greenland mosquitoes, finding low abundance and no core microbiota, with high diversity and sex-specific associations.

A new tool in a toolbox: Addressing challenges in high-throughput microbiota surveys across diverse wild insects

The paper introduces a high-throughput quantitative multi-target amplicon sequencing workflow to improve microbial community profiling in wild insects, addressing contamination and identification issues.

A Gridded Microclimate Dataset from a Sub-Arctic Biodiversity Hotspot in Finland

This paper presents a high-resolution microclimate dataset for a sub-Arctic biodiversity hotspot in Finland, generated using Random Forest models from 430 measurement locations.

A quantitative framework for investigating the reliability of network construction

The paper develops a framework to quantify uncertainty in ecological network construction due to stochasticity and sampling limitations.
