eCOMET: an R package for evaluating metabolic diversity and enrichment from LC‐MS/MS data to test ecological hypotheses from individuals to ecosystems

New Phytologist, Volume 252, Issue 4, Page 1675-1687, November 2026.
Overview of eCOMET workflows. Summary Methods in metabolomics have grown exponentially in recent years, providing new insight into the ecological function and evolutionary impact of diverse plant metabolites. Metabolomics requires a command of numerous tools, the outputs of which are typically integrated through in‐house custom code that presents a ...

Phylogenetic structure of conifers in regional floras in relation to climate and environmental heterogeneity worldwide

Ecography, Volume 2026, Issue 10, October 2026.
Despite having only about 670 species worldwide, conifers are one of the ecologically and economically most important plant groups. They have a rich fossil record and previous studies have shown that their current diversity is the result of past radiations, extinction, and dispersal events, restricting many genera to either the Northern or Southern ...

Mapping connectivity between important jaguar (Panthera onca) habitats in the Americas

Ecosphere, Volume 17, Issue 10, October 2026.
Abstract Habitat loss and reduced connectivity threaten the long‐term persistence of many large carnivore species across their ranges. Understanding connectivity among carnivore populations can bolster existing conservation strategies, and telemetry data from GPS collars are critical to informing these strategies.
