Fire season and drought influence fire effects on invasive grasses

In this Q&A, we discussed with author Charlotte Reemts the background behind her team’s recently published meta-analysis focused on invasive bluestems. Why study this group of grasses? Warm-season grasses from these two genera (Bothriochloa and Dichanthium) are interesting because they are important species in their native ranges but have also been introduced into other grasslands around the world. In many grasslands around the world, you … Continue reading Fire season and drought influence fire effects on invasive grasses

Agostina Torres: The order and timing of removal of invasive species influence community reassembly

Shortlisted for the 2024 Southwood Prize Agostina Torres introduces us to her latest research which evaluated the dependence of community reassembly on inverse priority effects by experimentally removing the target invasives in field and mesocosm communities. About the research Overview The study emerged as part of my PhD doctorate. Along with my supervisors, Drs. Martin Nuñez and Mariano Rodriguez-Cabal, we were trying to understand why … Continue reading Agostina Torres: The order and timing of removal of invasive species influence community reassembly

Early detection for invading tree pests: Targeted surveillance and stakeholder perspectives

Vasthi Alonso Chávez discusses how early detection of the emerald ash borer, responsible for the death of millions of ash trees in the United States, Canada, Russia and Eastern Europe, is essential for effective control. The growing volume of trade and travel across continents has accelerated the movement and introduction of pests and pathogens into regions outside their native range causing unprecedented ecological and economic … Continue reading Early detection for invading tree pests: Targeted surveillance and stakeholder perspectives

Detección temprana de plagas invasoras en árboles: Vigilancia optimizada y perspectivas sociológicas

Vasthi Alonso Chávez analiza cómo la detección temprana del barrenador esmeralda del fresno, responsable de la muerte de millones de fresnos en Estados Unidos, Canadá, Rusia y Europa del Este, es esencial para un control efectivo. El creciente volumen global del comercio y movimiento de árboles y sus productos, ha acelerado el transporte e introducción de plagas y enfermedades en regiones fuera de su área … Continue reading Detección temprana de plagas invasoras en árboles: Vigilancia optimizada y perspectivas sociológicas

Keeping our havened populations fighting fit: Do native predators help Australian mammals face invasive cats and foxes?

Linking to the recently-published article, Natasha Harrison discusses whether native predators inside ‘predator-free’ havens could be good for the conservation of threatened native prey species. Predator-free havens Since their introduction into the Australian landscape following European settlement, feral cats and red foxes have caused prolific population declines among our native fauna. The extinction of Australian mammals makes up more than two thirds of contemporary global … Continue reading Keeping our havened populations fighting fit: Do native predators help Australian mammals face invasive cats and foxes?

Tree species richness suppresses red imported fire ant invasion in a subtropical plantation forest

Chengjin Chu and co-authors discuss their latest research which presents a cross-trophic interaction study between the red imported fire ant and plants. The red imported fire ant (RIFA) is one of the most invasive insects in the world. Many pest management methods have been used to control the spread and damage of RIFA, like quarantine measures and powerful pesticides. However, one may wonder: Do more … Continue reading Tree species richness suppresses red imported fire ant invasion in a subtropical plantation forest

Ecological Associations of Lantana camara in an East African Savanna Park

Fredrick Ssali, Robert Baluku, Gilbert Drileyo and Moses Muhumuza recount their experience investigating the invasive flowering plant Lantana camara and its impact on common native species in western Uganda. Researchers at the Uganda Wildlife Research and Training Institute (UWRTI) teamed up with scientists from two Ugandan Universities and explored associations between Lantana camara and common native species in Queen Elizabeth National Park in western Uganda. … Continue reading Ecological Associations of Lantana camara in an East African Savanna Park

Creating innovative solutions to manage aquatic invasive species impacts

Author Sarah Kingsbury shares a new integrated management approach to better assess the effects and risks of aquatic invasive species on Atlantic salmon in Nova Scotia, Canada. Invasive species played key roles in the extinction of 60% of Earth’s plants and animals as reported by IPBES in 2023. While not all alien species introduced to new habitats become problematic (or even are able to establish … Continue reading Creating innovative solutions to manage aquatic invasive species impacts

Controlling an invasive shrub across the year with basal bark herbicide treatment

Nick Barber and colleagues share a new invasive plant management technique to better control invasive species and improve biodiversity. Controlling invasive plants can be a never-ending battle for land managers, and this work is costly — not just in materials like expensive herbicide, but costly in time as well. This is especially the case when invasive control efforts overlap with other management responsibilities. Managers have … Continue reading Controlling an invasive shrub across the year with basal bark herbicide treatment
