混合造林透過微生物和土壤有機碳的多樣性增強了土壤功能。

植樹造林常被視為恢復退化土地和改善土壤健康的策略,但並非所有造林模式都能產生相同的生態效益。土壤不僅為植物提供必需養分,還支持微生物活動、促進有機質分層並維持養分循環。 為了探討不同造林模式如何共同影響這些土壤功能,本研究比較了中國熱帶地區的裸地、純桉樹林、混合林和老齡天然林,評估了造林活動對土壤功能的影響。研究發現,造林顯著增強了土壤功能,且混合林的表現優於純林。進一步分析表明,土壤有機分子的多樣性是連接微生物碳特徵與土壤多功能的關鍵紐帶。 植樹造林——尤其是混合造林——增加了土壤有機碳分子的種類,從而促進了有機質分解、養分釋放及微生物功能的發揮。這些結果表明,熱帶地區的生態修復不應只關注植樹數量,更應重視樹種的選擇與群落組成。 在造林實踐中優先採用混合模式並專注於恢復土壤有機碳分子的多樣性,將有助於更有效地提升森林土壤健康與生態系統功能。 This is a Plain Language Summary discussing a recently published article in Journal of Applied Ecology.

Young owls stealing food from neighbors reduces chick survival

We sought to understand whether adding many nest boxes for barn owls, a common way to help control rodents on farms, might have hidden drawbacks. While more nest boxes can boost owl numbers, it is not always clear if this improves the survival of young birds. We studied barn owls in northern Israel using small electronic tags that recorded each time a bird entered a … Continue reading Young owls stealing food from neighbors reduces chick survival

Mixed tree planting boosts soil functions via microbial and Soil Organic Carbon (SOC) diversity

Afforestation is widely used to restore degraded land and improve soil health, but not all planting approaches deliver the same ecological benefits. Soils perform many important functions, including supplying nutrients to plants, supporting microbial activity, decomposing organic matter and maintaining nutrient cycling. However, how different afforestation strategies influence these functions together remains poorly understood. In this study, we compared four land-use types in tropical China: … Continue reading Mixed tree planting boosts soil functions via microbial and Soil Organic Carbon (SOC) diversity

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

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
