Availability of a Keystone Plant Resource Reduces Niche Overlap and Drives Distinct Species‐Specific Changes in Niche Breadth Among Small Rodents

Integrative Zoology, EarlyView.
We investigated how three rodent species respond to the seasonal availability of Araucaria angustifolia seeds. While Oligoryzomys spp. increased seed consumption and abundance during seed production, the more insectivorous Akodon paranaensis maintained a broader diet.

Statistical analyses of ecological multinomial time series to identify environmental drivers and biotic interactions

Methods in Ecology and Evolution, EarlyView.
Abstract Understanding the drivers of change in communities is a major goal of paleoecology and community ecology, but statistical inference from multivariate time series is challenged by relative (rather than absolute) abundance data, observation uncertainty and missing data due to uneven sampling through time.

SOUPE: An R package to test and optimise the phylogenetic and ecological representativeness of a taxonomic sample

Methods in Ecology and Evolution, EarlyView.
Abstract In the field of evolutionary biology, the selection of a phylogenetically representative sample is a crucial step to have a complete and accurate understanding of the studied group and the evolution of its traits. However, this step is often overlooked, and there is currently no objective way to assess the relevance of a sample for a given ...

Inferring alternative ecosystem states with field survey data

Methods in Ecology and Evolution, EarlyView.
Abstract Many ecosystems potentially exhibit alternative stable states, where distinct states can coexist under identical environmental conditions. While simulation models have generated key hypotheses in alternative stable states theory, they often rely on scale‐free parameters disconnected from real ecosystems.

Dealing With Inbuilt Age: A Bayesian Approach to Radiocarbon Dating of Rice, Bamboo and Charcoal From Non Ban Jak, Thailand

Archaeometry, EarlyView.
ABSTRACT New radiocarbon determinations from rice grains and bamboo have been obtained from Non Ban Jak, Northeast Thailand. These, along with charcoal, date a late Iron Age building sequence. The results come from short‐lived species and charcoal with potential inbuilt age. We built a series of Bayesian models to obtain a reliable chronology.
