What’s hiding beneath our feet? A new way to sample life in dryland soils

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 ground. Soil invertebrates hidden below … Continue reading What’s hiding beneath our feet? A new way to sample life in dryland soils

Prawns and crayfish as biocontrol agents against disease-transmitting freshwater snails

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 parasitic trematodes that harm … Continue reading Prawns and crayfish as biocontrol agents against disease-transmitting freshwater snails

Can rule-based mapping support nature recovery planning?

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 scales is not straightforward. Field surveys … Continue reading Can rule-based mapping support nature recovery planning?

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

Conservation is becoming more evidence-based, but it still has a long way to go

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 the wider literature and other forms of knowledge to … Continue reading Conservation is becoming more evidence-based, but it still has a long way to go

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
