Urbanization drives partner switching and loss of mutualism in an ant–plant symbiosis

open access: yesEcology, Volume 105, Issue 11, November 2024.
Abstract Mutualistic interactions between species underpin biodiversity and ecosystem function, but may be lost when partners respond differently to abiotic conditions. Except for a few prominent examples, effects of global anthropogenic change on mutualisms are poorly understood.

Towards a species‐level phylogeny for Neotropical Myrtaceae: Notes on topology and resources for future studies

open access: yesAmerican Journal of Botany, Volume 111, Issue 5, May 2024.
Abstract Premise Increasingly complete phylogenies underpin studies in systematics, ecology, and evolution. Myrteae (Myrtaceae), with ~2700 species, is a key component of the exceptionally diverse Neotropical flora, but given its complicated taxonomy, automated assembling of molecular supermatrices from public databases often lead to unreliable ...

Resource partitioning in a novel herbivore assemblage in South America

open access: yesJournal of Animal Ecology, Volume 93, Issue 5, Page 606-618, May 2024.
DNA metabarcoding was used to reveal differences in herbivory strategy among large herbivores at an Argentinian rewilding site. Based on diet composition, we find little evidence for resource competition between species. Instead, recently reintroduced native species and historically introduced non‐natives are likely expanding the range of herbivory ...
