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.

A field experiment characterizing variable detection rates during plant surveys

Conservation Biology, Volume 36, Issue 3, June 2022., 2022
Abstract Surveys aimed at finding threatened and invasive species can be challenging due to individual rarity and low and variable individual detection rates. Detection rate in plant surveys typically varies due to differences among observers, among the individual plants being surveyed (targets), and across background environments.

Evaluating unintended consequences of intentional species introductions and eradications for improved conservation management

Conservation Biology, Volume 36, Issue 1, February 2022., 2022
Abstract Increasingly intensive strategies to maintain biodiversity and ecosystem function are being deployed in response to global anthropogenic threats, including intentionally introducing and eradicating species via assisted migration, rewilding, biological control, invasive species eradications, and gene drives. These actions are highly contentious

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.

Experimental admixture among geographically disjunct populations of an invasive plant yields a global mosaic of reproductive incompatibility and heterosis

Journal of Ecology, Volume 109, Issue 5, Page 2152-2162, May 2021., 2021
Biogeographic patterns of variation in reproductive success in an invasive weed with allopatric distribution. Abstract Invasive species have the ability to rapidly adapt in the new regions where they are introduced. Classic evolutionary theory predicts that the accumulation of genetic differences over time in allopatric isolation may lead to ...

Efeito do espaçamento e do uso de leguminosas de cobertura no manejo de plantas invasoras em reflorestamento de Schizolobium amazonicum Huber ex. Ducke (paricá)

Revista Árvore, 2011
A infestação crescente de plantas invasoras em áreas de cultivos é um dos fatores que mais afetam os reflorestamentos na Amazônia, causando decréscimos na produtividade devido à competição direta pelos fatores de produção.
