Prescribed burns do not make pine trees more vulnerable to the pine processionary moth

Prescribed burning does not change how vulnerable pine trees are to pine processionary moth (PPM) caterpillars in the short term. This means land managers can use this tool without increasing or decreasing the risk of pest outbreaks. Warmer winters linked to climate change are helping the PPM move into new areas where it was previously absent, while also increasing its chances of survival. These caterpillars … Continue reading Prescribed burns do not make pine trees more vulnerable to the pine processionary moth

Monitoramento de longo prazo em florestas de várzea na Amazônia com gestão de base comunitária revela algumas das maiores densidades de onças-pintadas do mundo

O monitoramento de longo prazo mostra que as florestas alagáveis amazônicas (várzea) podem sustentar altas densidades de onças-pintadas, mas a aparente estabilidade pode mascarar um declínio populacional subjacente, destacando a necessidade de esforços contínuos de conservação diante do aumento de eventos climáticos extremos. As onças-pintadas são o maior felino das Américas e desempenham um papel fundamental na manutenção do funcionamento dos ecossistemas. Em grande parte … Continue reading Monitoramento de longo prazo em florestas de várzea na Amazônia com gestão de base comunitária revela algumas das maiores densidades de onças-pintadas do mundo

Long-term monitoring in community-managed Amazonian floodplains reveals some of the world’s highest jaguar densities

Long-term monitoring shows that Amazonian floodplain forests (várzea) can support high jaguar densities, but apparent stability may mask underlying population decline, highlighting the need for sustained conservation efforts under increasing climate extremes. Jaguars are the largest felid in the Americas and play a key role in maintaining ecosystem function. Across much of their range, populations have declined due to habitat loss, hunting, and human–wildlife conflict. … Continue reading Long-term monitoring in community-managed Amazonian floodplains reveals some of the world’s highest jaguar densities

When fire meets warming: Managing mountain grasslands in a hotter world

Fire has shaped mountain grasslands for thousands of years and remains essential for keeping them healthy. But as the climate warms, we need to understand how rising temperatures and fire together will affect these ecosystems. In our study, we tested how warming and different fire frequencies interact in the Drakensberg Mountains of South Africa. In 2017, we added small open top chambers to a long-running … Continue reading When fire meets warming: Managing mountain grasslands in a hotter world

Biodiversity in soil seedbanks remains high after low-intensity fire

Prescribed burning is the act of intentionally burning an ecosystem and is used in fire-prone regions around the world to manage fuel loads or conserve biodiversity. Some ecosystems experience fires that are too hot or occur too frequently, while other areas suffer from a lack of fire. Prescribed burning at the right intensity and frequency can help minimise the risk of wildfire while also promoting … Continue reading Biodiversity in soil seedbanks remains high after low-intensity fire

Come migliorare la stima dell’abbondanza locale dei pesci costieri del Mediterraneo

Stimare quanti pesci vivono nelle aree costiere è fondamentale per proteggere gli ecosistemi marini e gestire le risorse in modo sostenibile. In questo studio, mettiamo in evidenza che il DNA presente nell’acqua di mare può aiutare a stimare meglio l’abbondanza dei pesci. Infatti, contare i pesci non è sempre facile. I metodi tradizionali, come quelli basati su catture di pesca, possono essere costosi, distruttivi o … Continue reading Come migliorare la stima dell’abbondanza locale dei pesci costieri del Mediterraneo

Mejorando las estimaciones de la abundancia de los peces costeros del Mediterráneo

Conocer cuántos peces hay en nuestras costas es esencial para proteger los ecosistemas marinos y asegurar una gestión sostenible de los recursos. En este estudio, demostramos que el ADN que hay en agua de mar puede ser una herramienta clave para ayudar a predecir mejor la abundancia de dichos peces. Contar peces no siempre es tarea fácil. Los métodos tradicionales, como la pesca, pueden ser … Continue reading Mejorando las estimaciones de la abundancia de los peces costeros del Mediterráneo

Comment mieux estimer l’abondance locale des poissons côtiers de Méditerranée

Estimer combien de poissons vivent dans les zones côtières est essentiel pour protéger les écosystèmes marins et gérer durablement les ressources. Dans cette étude, nous montrons que l’ADN présent dans l’eau de mer peut aider à mieux prédire l’abondance des poissons. En effet, compter les poissons n’est pas toujours simple. Les méthodes classiques, comme les captures de pêche, peuvent être coûteuses, destructrices ou difficiles à … Continue reading Comment mieux estimer l’abondance locale des poissons côtiers de Méditerranée

How to better estimate local abundance of Mediterranean coastal fish

Estimating how many fish live in coastal areas is essential for protecting marine ecosystems and managing resources sustainably. In this study, we show that DNA present in seawater can help better predict fish abundance. Indeed, counting fish is not always easy. Traditional methods, such as fishing catches, can be costly, destructive, or difficult to implement in certain protected or dangerous areas. A recent method involves … Continue reading How to better estimate local abundance of Mediterranean coastal fish

Creating small clearings helps herbivores keep trees from taking over savannas

In many parts of the world, grasslands and savannas are being taken over by trees. This change reduces biodiversity and alters how these ecosystems work. We wanted to test a simple, low-cost way to slow this process and help restore open grassy areas. In our study, we created small clearings (“glades”) by cutting trees in a heavily wooded savanna in South Africa. We compared these … Continue reading Creating small clearings helps herbivores keep trees from taking over savannas
