Coverage‐based rarefaction fails to quantify relative species richness

Oikos, EarlyView.
Coverage‐based rarefaction (CBR) is a high‐profile tool for assessing biodiversity that provides relative species richness estimates by leveraging the Good‐Turing index u to interpolate. In contrast to alternatives such as the Shannon and Simpson indices, CBR's main appeal is providing values in units of species. CBR is tested against a series of other

Coexisting ant species differ in ability to meet their intrinsic nutritional needs

Oikos, EarlyView.
Coexisting species are often assumed to reduce competition by foraging for foods that differ in nutrient composition, but few studies test whether field nutritional differences correspond to intrinsic differences in macronutrient selectivity. We compared field estimates of worker trophic position (tissue isotopes: δ15N) and worker tissue stoichiometry (

CSRcalculator: A reproducible framework for understanding plant ecological strategies

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants respond to environmental change is essential for conserving biodiversity and managing ecosystems under climate change. We developed CSRcalculator, an open‐source platform that brings together major competitor, stress‐tolerator, ruderal (CSR) models to make ecological strategy classification accessible, reproducible and scalable.

How many bromeliads are there? History and future perspectives of species scientific discovery in the pineapple family

PLANTS, PEOPLE, PLANET, EarlyView.
It remains unclear how many plant species are not yet recorded by science. We illustrated the process by which species of the pineapple family in tropical America have been newly described to science to date, and we estimated how many species may still await scientific discovery in this group.
