Where is the UK's pollinator biodiversity? The importance of urban areas for flower-visiting insects
Proceedings of the Royal Society B: Biological Sciences, 2015 Insect pollinators provide a crucial ecosystem service, but are under threat. Urban areas could be important for pollinators, though their value relative to other habitats is poorly known.

Utilizing Causal Network Markers to Identify Tipping Points ahead of Critical Transition
Advanced Science, EarlyView.The study proposes a causal network markers (CNMs) framework to identify early‐warning signals preceding critical transitions. It validates CNMs on various computational benchmark models and real‐world datasets, demonstrating higher accuracy and flexibility compared to existing approaches.

Advanced Science, EarlyView.Researchers have identified a citrus chimera with distinctive tissue origins and carotenoid profiles. It is discovered that fruit tissues develop from all three cell layers but in different proportions. A key transcription factor, MYB107, regulates β‐cryptoxanthin production by directly activating carotenoid biosynthesis genes, explaining why some ...

Flowers respond to pollinator sound within minutes by increasing nectar sugar concentration
bioRxiv, 2018 Can plants hear? That is, can they sense airborne sounds and respond to them? Here we show that Oenothera drummondii flowers, exposed to the playback sound of a flying bee or to synthetic sound-signals at similar frequencies, produced sweeter nectar ...

Recognition of flowers by pollinators
Current Opinion in Plant Biology, 2006 The flowers of angiosperm plants present us with a staggering diversity of signal designs, but how did this diversity evolve? Answering this question requires us to understand how pollinators analyze these signals with their visual and olfactory sense organs, and how the sensory systems work together with post-receptor neural wiring to produce a ...

Advanced Science, EarlyView.This study identifies the mitochondrial protein RTA9, a member of the Domain of Unknown Function 641 family, together with its partner S40, as key regulators of aphid resistance in maize. RTA9 promotes S40 degradation and modulates reactive oxygen species accumulation.

Using stable isotopes in hummingbird breath to estimate reliance on supplemental feeders
Ecology and Evolution, 2023 Understanding the ecological consequences of supplemental feeding to both hummingbirds and the plants they pollinate is complicated by logistical challenges associated with assessing relative dietary resource use with commonly applied observational ...
