The Applied Ecologist

In our ‘Field Diaries’ series, The Applied Ecologist is sharing stories from a range of different fieldwork experiences.  About the author Mallika Sardeshpande, She/her Affiliation: Ecology interests: Agroecology, Urban ecology, Green infrastructure Overview of fieldwork In 2024, I secured my first applied project grant, to work on indigenous agroforestry in the Mpondoland Centre o…

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.…

By Walter R Jubber, Andrea Fuller, Maria Paniw Drylands cover over 40% of Earth’s land surface. When we think about biodiversity in drylands, we often picture aboveground shrubs, flowers sprouting after rain, grazing animals, and maybe insects scurrying across the surface. But a key adaptation to extreme temperatures and aridity, especially for invertebrates, is spending most of their life below …

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 …

Moscovitz et al. share their experience comparing between predation preferences of a prawn and a crayfish over four species of snails which are aquacultural pests, explaining the observed preferences – or lack thereof – by quantifying snail traits. Freshwater snails are tiny – but in aquaculture systems, they loom large. In fishponds around the world, snails act as intermediate hosts for parasiti…

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 lon…

Reliable habitat maps sit at the heart of biodiversity monitoring, natural capital accounting and nature recovery planning. Recent policy developments in the UK have made this even more important. The UK Land Use Framework highlights the need for a coherent national land-use evidence base and better integration of spatial data across sectors. However, producing consistent habitat maps at large sc…

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 promot…

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 …

Written by Alec Christie, Centre for Environmental Policy, Imperial College London. For more than two decades, conservationists have been encouraged to use the best available evidence to inform their decisions – a concept called ‘Evidence-based Conservation’. The idea is simple: rather than relying only on personal experience, tradition, or intuition, practitioners should draw on evidence from th…

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 relat…

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 biologic…

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 understan…

We discovered that climate change could dramatically break the natural highways that connect coral reefs across the southwestern Pacific Ocean, but one location may survive as a critical refuge. Coral reefs don’t exist in isolation. When reefs are damaged by bleaching or storms, they recover through baby corals (larvae) that drift from healthy reefs on ocean currents. These “larval highways” conn…

Shortlisted for the Georgina Mace Prize About the research Overview Our paper focuses on understanding whether the ecological fears surrounding tidal energy are actually backed by evidence. Tidal power is a reliable, clean, and predictable renewable energy source, yet projects are frequently delayed or cancelled due to concerns about environmental harm. We systematically reviewed the empirical li…

Shortlisted for the 2025 Southwood Prize About the research Overview Seeds can accelerate the restoration of degraded landscapes. But where should practitioners source them, especially as the climate changes? In our latest paper, we address this by proposing a spatially explicit tool that identifies the best areas for sourcing seeds for ecosystem restoration under different strategies, from prior…

Shortlisted for the Chico Mendes Prize About the research Overview My research investigates the ecological adaptation of a translocated sub-adult male Asian elephant (Elephas maximus) as a strategy to mitigate increasing human-elephant conflict (HEC). By tracking a satellite-collared individual relocated from its original conflict zone, I sought to determine if a relocated elephant can successful…

Shortlisted for the 2025 Southwood Prize About the research Overview Coastal areas are increasingly vulnerable to hazards such as erosion and flooding, and there is growing recognition that nature-based approaches can play an important role in coastal protection because they can adapt to changing environmental conditions. As new approaches are developed, it is important to test how well they perf…

Shortlisted for the 2025 Southwood Prize About the research Overview Our paper explores how two closely related wild equids—Przewalski’s horses and Asiatic wild asses—coexist in the extremely water-limited deserts of the Dzungarian Gobi. Classical niche theory would predict competitive exclusion under such scarcity, especially since horses are more water-dependent. By combining controlled water-u…

Shortlisted for the Georgina Mace Prize About the research Palaeoecology – the ecology of the past – has much to offer in addressing complex conservation challenges. By providing a long-term perspective of ecological change, palaeoecology can provide insight on pre-disturbance conditions, long-term processes, and the responses of ecological systems to dynamic climatic and anthropogenic change. Ho…
