Essential tools but overlooked bias: Artificial intelligence and citizen science classification affect camera trap data

Methods in Ecology and Evolution, EarlyView.
Abstract Camera trapping generates vast image datasets requiring classification before downstream ecological inference, yet the influence of classification errors on subsequent analyses is often overlooked. Classification performance can vary widely depending on the classification method (e.g. citizen science vs. artificial intelligence [AI]), species,

Quantifying macro‐evolutionary patterns of trait mean and variance with phylogenetic location–scale models

Methods in Ecology and Evolution, EarlyView.
Abstract Understanding how both the mean (location) and variance (scale) of traits differ among species and lineages is fundamental to unveiling macroevolutionary patterns. Yet, traditional phylogenetic comparative methods primarily focus on modelling mean trait values, often overlooking variability and heteroscedasticity that can provide critical ...

Fetal exposure to a mixture of endocrine‐disrupting chemicals and biomarkers of male fecundity: A population‐based cohort study

Andrology, EarlyView.
Abstract Background Fetal exposure to endocrine‐disrupting chemicals (EDCs) has been associated with reduced male fecundity, but with few studies considering chemical mixtures. Objectives We assessed the association between fetal exposure to a mixture of EDCs and biomarkers of male fecundity in young adulthood.

Estimation of Daily Smoking Prevalence for Disaggregated Statistical Areas in Australia

Australian &New Zealand Journal of Statistics, EarlyView.
ABSTRACT Motivated by the need to estimate prevalence at multiple disaggregated level hierarchies, rather than only one, this study extends widely used area‐level models in Bayesian and frequentist framework. We propose adding additional unstructured random effects at higher level disaggregated domains to the traditional models. Using our extension, we

Joint analysis of dispersed count‐time data using a bivariate latent factor model

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract In this study, we explore parameter estimation for a joint count‐time data model with a two‐factor latent trait structure, representing accuracy and speed. Each count‐time variable pair corresponds to a specific item on a measurement instrument, where each item consists of a fixed number of tasks.

Differential effects of freshwater browning across fish species: consequences for individual‐ to community‐level fish traits in north temperate lakes

Biological Reviews, EarlyView.
ABSTRACT The browning of freshwater ecosystems is increasingly evident in temperate and northern regions, with widespread ramifications for lake physics, chemistry, and biology. Contrasting results on how freshwater browning may impact fish have been reported, but there has been no comprehensive examination of how browning may cause cascading effects ...

Breeding habitat preferences and niche partitioning of insectivorous songbirds in Alpine grasslands

Ibis, EarlyView.
Alpine grasslands are increasingly facing pressures of climate and land‐use changes. Higher temperatures and pastoral abandonment lead to treeline shift and to bush encroachment, while agricultural intensification causes soil eutrophication and landscape homogenization. Alpine grasslands in Europe host important populations of mountain specialists that

Associations between soil characteristics and ground‐nesting bees on farms Associations entre les caractéristiques du sol et les abeilles terricoles dans les exploitations agricoles

Insect Conservation and Diversity, EarlyView.
We collected ground‐nesting bees at 35 farms over two summers and assessed their abundance, diversity, and community composition in relation to local soil characteristics (texture, compaction, slope, and ground cover). Ground‐nesting bee abundance and species richness increased with bare ground and sand content.

eDNA metabarcoding of archived leaf samples reveals arthropod diversity decline in South Korean but not in German forest ecosystems

Insect Conservation and Diversity, EarlyView.
Environmental samples from the South Korean (A) and German (B) Environmental Specimen Banks were analysed regarding long‐term trends in canopy‐associated arthropod communities over 11 years. Samples of both Environmental Specimen Banks showed tree species‐specific arthropod communities that were significantly different from other tree species ...
