The specialised buzz pollination syndrome poses a partial barrier to plant invasions

open access: yesJournal of Ecology, Volume 112, Issue 8, Page 1686-1700, August 2024.
We found that plants that exhibit traits consistent with the buzz‐pollination syndrome are underrepresented as invasive species across the globe. Our result suggests that the specialist buzz‐pollination syndrome poses a partial barrier to plant invasions. Our review also highlighted six alternative insect behaviours that can enable invasive plants with

The potential influence of genome‐wide adaptive divergence on conservation translocation outcome in an isolated greater sage‐grouse population

open access: yesConservation Biology, Volume 38, Issue 4, August 2024.
Abstract Conservation translocations are an important conservation tool commonly employed to augment declining or reestablish extirpated populations. One goal of augmentation is to increase genetic diversity and reduce the risk of inbreeding depression (i.e., genetic rescue).

Modeling the risk of aquatic species invasion spread through boater movements and river connections

open access: yesConservation Biology, Volume 38, Issue 4, August 2024.
Abstract Aquatic invasive species (AIS) are one of the greatest threats to the functioning of aquatic ecosystems worldwide. Once an invasive species has been introduced to a new region, many governments develop management strategies to reduce further spread.

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 ...
