New study on factors influencing collisions of Red Kite Milvus milvus with wind turbines: findings suggest that turbines with rotor diameters <90m and clearances > 60m may pose a lower relative threat to Red Kites. Read more here: doi.org/10.1016/j.bi...

Which bird disperses which plant? What does bird dispersed fruit look like? Why do fruit sizes differ between regions? Why does ivy fruit in winter? How can we identify the disperser and distance carried from droppings? How did this collaboration arise? youtu.be/4vZ0w97ffRM?...

A study by the WSL and @vogelwarte.bsky.social using long-term data has shown that bark beetles are good for woodpeckers🪲🐦: woodpeckers use the dead wood produced by bark beetle infestations as shelter and nesting sites🪵. WSL-News: www.wsl.ch/en/news/why-...

Why bark beetles are good for woodpeckers
In a study based on long-term data, WSL researchers show that woodpecker populations grow when there is more deadwood.

What looked like a hearing organ on a tiny stinkbug’s leg turned out to be something far stranger: a fungal nursery that mother bugs use to coat their newly laid eggs in protective symbiotic hyphae, shielding their offspring from parasitic wasps.

(A) An adult female in the field on Sicyos angulatus. (B) Back view of an adult female reared on cucumber, whose hindleg organs are covered with fungal hyphae (arrowheads). (C) Magnified image of the hindleg organ. (D to L) Morphology of hind tibia of adult male [(D) to (F)], immature adult female [(G) to (I)], and mature adult female [(J) to (L)]. [(D), (G), and (I)] Brightfield images. [(E), (H), and (K)] Scanning electron microscope (SEM) images. [(F), (I), and (L)] Magnified SEM images. (M to O) Peculiar behavior of egg-laying adult female. After laying each egg (M), the female rhythmically scratches the hyphae-covered hindleg organ with tarsal claws of the opposite hindleg (N) and then rubs the egg surface with the claws in a skillful manner (O). Also see movie S1. (P to R) Egg mass covered with fungal hyphae at 0-day (P), 3-day (Q), and 10-day (R) intervals after oviposition. Reddish color of 10-day eggs reflects the body color of developing nymphs inside.

Our study reveals how barn owl parents coordinate nightly chick feeding. Females step up when males underperform & pairs that meet more often at the nest share work more equally boosting chick survival🦉

🍃🌳🍂 #PhDAlert! MSc in #ForestEcology, #PlantPhysiology or #EnvironmentalSciences? Eager to apply a wide range of approaches, from #ecophysiology and experimental fieldwork to #RemoteSensing and modelling🛰️? We offer a #PhD position in Tree #Phenology: apply.refline.ch/273855/1788/... #ScienceJobs
Job offer: The Swiss Federal Institute for Forest, Snow and Landscape Research WSL is part of the ETH Domain. Approximately 600 people work on the sustainable use and protection of the environment and on the handling of natural hazards. The Research Unit Forest and Soil Ecology, which investigates how changing environmental conditions affect forest ecosystem functioning, is seeking a candidate to join the Ecosystem Ecology group starting on 1 January 2026 (or upon appointment) as a PhD candidate in Tree Phenology and Ecophysiology You will be working within the SNF funded project “From leaf-out to senescence: integrating daylight and temperature dynamics into phenological process-based models to enhance autumn phenology modelling”. Unlike leaf-out timing, leaf senescence is particularly challenging to predict, partly because many internal factors are involved and remain poorly understood. You will investigate how changing environmental conditions — including variations in temperature, daylight, and water availability — affect leaf senescence, with the goal of improving phenological models. To achieve this, you will combine manipulative experiments, long-term phenological observations, and large-scale remote sensing data. You will also apply both statistical and mechanistic modelling approaches and contribute to publishing results in international scientific journals. You hold a Master’s degree in in forest ecology, ecology, plant physiology, environmental science, or a related field. You are eager to apply a wide range of approaches, from ecophysiology and experimental fieldwork to remote sensing and modelling. You have a good command of English, work in a structured and independent manner, enjoy collaborating within a team and are comfortable using statistical software, preferably R. The workplace will be at WSL in Birmensdorf (approximately 20 minutes outside of Zurich), and the PhD enrolment will be at the University of Bern.

A nearly microscopic bug that has a bulbous body, an ant-like head, and two long antennae crawls on a thin piece of wood which has a slime mold growing on it. The slime mold has a short white stalk and the top is a long cylindrical-shaped, reflective thing. It looks like a small bean but reflects a faint blue, green and purple in the light.
