Can AI improve decision-making in applied ecology? Only if we guide it well

Artificial intelligence (AI) is rapidly entering our daily lives. As the world begins to rely on it for small decisions, such as choosing which furniture suits our garden décor, scientists are witnessing a much larger shift quietly unfolding. AI is now entering ecology, and more importantly, applied ecology, a field that supports real-time high-stakes decision-making for our planet and posterity. AI-based tools can identify species … Continue reading Can AI improve decision-making in applied ecology? Only if we guide it well

Vehicle lighting can reduce the risk of wildlife-vehicle collisions

Every year, vehicle collisions with deer and wild pigs cause billions of dollars in damages and injure thousands of drivers. Most collisions occur at night when the animals are more active and when it is more difficult for drivers to see. Recent research has found that illuminating the front end of the vehicle with a lightbar can reduce dangerous encounters with deer, and newer light … Continue reading Vehicle lighting can reduce the risk of wildlife-vehicle collisions

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

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

Species lists can mislead: Island management should map species interactions

Seed dispersal is essential for plant regeneration, especially on islands where many plants rely on animals to move seeds to safe places to survive. But because this process is hard to observe directly, conservation decisions often fall back on easier measures such as species counts. This can be misleading, because ecosystems are not only defined by the species they contain, but also by the relationships … Continue reading Species lists can mislead: Island management should map species interactions

Grazing intensity, duration, and regime and livestock type modulate soil microbiota responses

Grasslands account for approximately 40% of the Earth’s land area and are the largest natural ecosystem apart from forests. Livestock grazing is currently the most important human activity in grasslands, with a persistent and strong impact on both the aboveground plant community and underground organisms. Soil microbiota are the most numerous, most diverse, and functionally crucial biological group on the planet. Among them, microbes and … Continue reading Grazing intensity, duration, and regime and livestock type modulate soil microbiota responses

Navegando los obstáculos del río: La influencia de la tipología de presas de baja altura y la hidrología fluvial en la conectividad genética de los peces

Los ríos están llenos de pequeñas represas que vuelven el curso del agua más lento y complican el desplazamiento de organismos acuáticos (por ejemplo, de los peces). Estas pequeñas represas por lo general solo tienen unos metros de altura y están presentes a través del mundo. Ya que no es posible eliminar todas estas represas, es fundamental identificar cuáles (o más bien qué características) representan … Continue reading Navegando los obstáculos del río: La influencia de la tipología de presas de baja altura y la hidrología fluvial en la conectividad genética de los peces

Naviguer à travers les obstacles fluviaux : L’influence de la typologie des barrages de faible hauteur et de l’hydrologie des rivières sur la connectivité génétique des poissons

Les rivières sont parsemées de petits barrages qui ralentissent l’eau et compliquent les déplacements des organismes aquatiques, tels que les poissons. Ces petits barrages mesurant généralement quelques mètres de haut sont des millions dans le monde. Comme il est impossible de tous les supprimer, il est essentiel d’identifier ceux qui posent les plus gros problèmes pour le déplacement de la faune aquatique. Dans notre étude, … Continue reading Naviguer à travers les obstacles fluviaux : L’influence de la typologie des barrages de faible hauteur et de l’hydrologie des rivières sur la connectivité génétique des poissons

Navigating river obstacles: The influence of the typology of low-head dams and river hydrology on fish genetic connectivity

Rivers are dotted with countless small dams that slow the flow of water and disrupt connections between fish populations. These structures, known as low-head dams, typically stand only a few metres tall, yet millions exist worldwide. Since removing all of them is unrealistic, it is crucial to identify which ones most strongly hinder aquatic wildlife movement. In our study, we set out to understand how … Continue reading Navigating river obstacles: The influence of the typology of low-head dams and river hydrology on fish genetic connectivity
