Distribución de plantas nativas y exóticas a lo largo de gradientes de elevación en senderos de montaña en los Andes de Mendoza, Argentina

Boletín de la Sociedad Argentina de Botánica, 2023
Introducción y objetivos: El cambio climático, el ganado y el creciente uso turístico favorecen la dispersión de plantas exóticas, amenazando la conservación de los ecosistemas altoandinos.

Wild herbivores enhance resistance to invasion by exotic cacti in an African savanna

Journal of Ecology, Volume 111, Issue 1, Page 33-44, January 2023., 2023
Our experimental and observational findings that wild herbivores confer resistance to invasion by exotic cacti add to evidence that conserving and restoring native herbivore assemblages (particularly megaherbivores) can increase community resistance to plant invasions. Photo credit: Gustavo Lozada (same for potential cover image). Abstract Whether wild

Water use partitioning of native and non‐native tree species in riparian ecosystems under contrasting climatic conditions

Functional Ecology, Volume 36, Issue 10, Page 2480-2492, October 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract One of the suggested mechanisms behind the success of non‐native plants in recipient ecosystems is competition avoidance with natives by means of different resource‐use strategies, such as deeper water uptake under dry conditions.

Consensus and controversy in the discipline of invasion science

Conservation Biology, Volume 36, Issue 5, October 2022., 2022
Abstract Approaches, values, and perceptions in invasion science are highly dynamic, and like in other disciplines, views among different people can diverge. This has led to debate in the field specifically surrounding the core themes of values, management, impacts, and terminology.

Effects of time since invasion and control actions on a coastal ecosystem invaded by non‐native pine trees

Ecological Solutions and Evidence, Volume 3, Issue 1, January–March 2022., 2022
Pine invasion reduced native species abundance, plant cover, richness and diversity, with an increase over time since invasion. Species diversity and richness were lower in the managed area than in the area that had not been invaded. Restoration activities are therefore required to increase native species diversity.

bRacatus: A method to estimate the accuracy and biogeographical status of georeferenced biological data

Methods in Ecology and Evolution, Volume 12, Issue 9, Page 1609-1619, September 2021., 2021
Abstract Georeferenced biological data of species distributions, abundances or traits are critical for ecological and evolutionary research. However, the accuracy (true vs. false records) and biogeographical status (native vs. alien) of individual georeferenced records are often unclear, which limits their use in species distribution modelling ...
