Shifting balance between habitat and climate in boreal biodiversity patterns across space, time and taxa
Abstract Climate and habitat are key drivers of biodiversity patterns. However, how they independently and jointly affect species distribution across space, time, and taxa remains poorly understood. Here, we evaluate the relative importance of habitat and climate variables underpinning occurrence and abundance patterns of 503 terrestrial animal species over 20 years and a ~ 1100 km latitudinal gradient in Finland.
Is There a Fly in My Soup? To What Extent Do Metabarcoding and Individual Barcoding Tell the Same Story?
1 Introduction Metabarcoding of arthropod samples is rapidly becoming the go-to method for biodiversity discovery (Cristescu 2014; Souto-Vilarós et al. 2024; Yu et al. 2012), community comparisons (Barsoum et al. 2019; Taberlet et al. 2012), ecological monitoring (Granqvist et al. 2025; van Klink et al. 2022, 2024) and testing of topical theories in community ecology (Abrego et al. 2021; Andújar et al. 2022).
Global dataset of soil eukaryotic communities created with a uniform protocol and long read sequencing
|
Abstract Soil eukaryotes, including fungi, protists, plants, and animals, are central to biosphere functioning and resilience. The Global Standardised Soil Eukaryome Dataset (GloSED) is the first dataset encompassing the entire spectrum of soil eukaryotes, covering 4,063 sampling sites in 121 countries on all continents, revealing nearly one million operational taxonomic units. All samples were collected and analysed using a standardised protocol minimizing technical biases.

A multi-modal dataset for insect biodiversity with imagery and DNA at the trap and individual level
|
Abstract Insects comprise millions of species, many experiencing severe population declines under environmental and habitat changes. High-throughput approaches are crucial for accelerating our understanding of insect diversity, with DNA barcoding and high-resolution imaging showing strong potential for automatic taxonomic classification. However, most image-based approaches rely on individual specimen data, unlike the unsorted bulk samples collected in large-scale ecological surveys.

Assessing the Ecological Network of Svalbard Through Scaled Interaction Strength Data: Insights From a Century of Research
1 Ecosystem Monitoring in a Changing Arctic One of the key aims of ecological monitoring is to describe changes in the state of species within communities over time. Importantly, communities consist not only of species but of the interactions between them. For this reason, communities can conveniently be described as networks, and our interest should focus on changes in the state of both nodes (species, or groups of species with a similar ecological role) and interactions (links) between them.
A digital twin for real-time biodiversity forecasting with citizen science data - Nature Ecology & Evolution
|
Abstract Citizen science provides large amounts of biodiversity data. Key challenges in unlocking its full potential include engaging citizens with limited species identification skills and accelerating the transition from data collection to research and monitoring outputs. Here we use a large dataset from Finland to show how even citizens who cannot identify birds themselves can contribute to real-time predictions of avian distributions.

Strong diel variation in the activity of insect taxa sampled by Malaise traps
INTRODUCTION During the past decade, a number of studies have reported an alarming loss of insect biodiversity and biomass across the world (Hallmann et al., 2017; Mühlethaler et al., 2024; van Klink et al., 2024; Wagner et al., 2021).
Benchmarking metabarcode sequence denoisers for improved invertebrate community diversity estimates
1 INTRODUCTION DNA metabarcoding is fast becoming a method of choice for the inventory and monitoring of community-level arthropod biodiversity (Arribas et al., 2022; Kennedy et al., 2020), with growing interest in the recovery of haplotype-level variation within species from metabarcoding reads (Andújar et al., 2022; Serrana & Watanabe, 2021; Shum & Palumbi, 2021).
Common to rare transfer learning (CORAL) enables inference and prediction for a quarter million rare Malagasy arthropods - Nature Methods
Abstract DNA-based biodiversity surveys result in massive-scale data, including up to millions of species—of which, most are rare. Making the most of such data for inference and prediction requires modeling approaches that can relate species occurrences to environmental and spatial predictors, while incorporating information about their taxonomic or phylogenetic placement.
Human contributions to global soundscapes are less predictable than the acoustic rhythms of wildlife - Nature Ecology & Evolution
|
Abstract Across the world, human (anthropophonic) sounds add to sounds of biological (biophonic) and geophysical (geophonic) origin, with human contributions including both speech and technophony (sounds of technological devices). To characterize society’s contribution to the global soundscapes, we used passive acoustic recorders at 139 sites across 6 continents, sampling both urban green spaces and nearby pristine sites continuously for 3 years in a paired design.

The environmental dependence of ecological interaction networks
Abstract Interactions between species are often assumed to occur whenever species pairs co-occur, allowing us to reconstruct local ecological networks from a deterministic 'metaweb'. Thus, a species' set of metaweb interactions defines its Eltonian niche - the biotic conditions under which it can exist. However, both species and interactions may also have Grinnellian niches, reflecting relationships between probability of occurrence and environmental conditions.
Projected loss of brown macroalgae and seagrasses with global environmental change - Nature Communications
Abstract Although many studies predict extensive future biodiversity loss and redistribution in the terrestrial realm, future changes in marine biodiversity remain relatively unexplored. In this work, we model global shifts in one of the most important marine functional groups—ecosystem-structuring macrophytes—and predict substantial end-of-century change.
How to shorten scientific manuscripts
As young scientists, we thought that article length was restricted due to high printing costs and competition for space. Since then, the length of journal articles appears to have decreased rather than increased—even though nothing is currently printed. This trend may be symptomatic of an age of information overflow, where we need to be succinct to keep the attention of our audience.
Global arthropod beta-diversity is spatially and temporally structured by latitude - Communications Biology
|
Abstract Global biodiversity gradients are generally expected to reflect greater species replacement closer to the equator. However, empirical validation of global biodiversity gradients largely relies on vertebrates, plants, and other less diverse taxa. Here we assess the temporal and spatial dynamics of global arthropod biodiversity dynamics using a beta-diversity framework.

Towards a toolkit for global insect biodiversity monitoring
Insects are the most species-rich group of animals on Earth, and, together with other arthropods, make up most of the terrestrial animal biomass [1]. They provide a myriad of ecosystem functions and interact with species across the tree of life.
Mixed effects of a national protected area network on terrestrial and freshwater biodiversity - Nature Communications
Abstract Protected areas are considered fundamental to counter biodiversity loss. However, evidence for their effectiveness in averting local extinctions remains scarce and taxonomically biased. We employ a robust counterfactual multi-taxon approach to compare occupancy patterns of 638 species, including birds (150), mammals (23), plants (39) and phytoplankton (426) between protected and unprotected sites across four decades in Finland.
Environmental responses of fruiting fungal communities are phylogenetically structured
Statistical modelling To simultaneously estimate how the fruiting fungal species responded to the environmental covariates and how phylogenetically structured those responses were, we used hierarchical modelling of species communities (HMSC, Ovaskainen et al. 2017, Ovaskainen and Abrego 2020).
Different spatial structure of plant‐associated fungal communities above‐ and belowground
Different patterns suggest different assembly processes For foliar fungal communities, the current lack of an imprint of microclimatic conditions, host characteristics and spatial connectivity, and the weak spatial patterning across the landscape, might suggest a lack of dispersal limitation among trees at the landscape scale.
Convergence of dominance and neglect in flying insect diversity - Nature Ecology & Evolution
Abstract Most of arthropod biodiversity is unknown to science. Consequently, it has been unclear whether insect communities around the world are dominated by the same or different taxa. This question can be answered through standardized sampling of biodiversity followed by estimation of species diversity and community composition with DNA barcodes.
Site-specific length-biomass relationships of arctic arthropod families are critical for accurate ecological inferences
New Results doi: https://doi.org/10.1101/2023.04.04.534924 Abstract Arthropods play an essential role in terrestrial ecosystems, not least by forming the food base for insectivorous birds. To better understand such trophic interactions, it is essential to monitor seasonal trajectories in arthropod biomass.

Climate change reshuffles northern species within their niches - Nature Climate Change
|
Abstract Climate change is a pervasive threat to biodiversity. While range shifts are a known consequence of climate warming contributing to regional community change, less is known about how species’ positions shift within their climatic niches. Furthermore, whether the relative importance of different climatic variables prompting such shifts varies with changing climate remains unclear.
