9 . An ancient, interdependent relationship that contributes to food systems and ecosystem stability across the globe could be changing.
Many flowering plants can self-pollinate (自花传粉), or transfer pollen between their own blossoms for seed generation and reproduction, but most of these plants have relied on pollinators such as butterflies and bees to reproduce. Now — during declines reported in many pollinator populations — a new study on the evolution of one flower species’ mating system has revealed a remarkable change that could worsen the challenges faced by the plants’ insect partners.
The flowers reproductive evolution may be linked to environmental changes such as habitat destruction and rapid ongoing decreases in pollinator biodiversity, according to Samson Acoca-Pidolle, who led the study published December 19 in the journal New Phytologist.
Comparing seeds of wild field pansies (三色堇) collected decades ago in France with the plants’ modern descendants. Acoca-Pidolle and his colleagues discovered that today’s flowers are smaller and produce less nectar (花蜜) as a result of increased self-pollination, which has direct impacts on pollinator behavior.The pansies of the past self-fertilized less and attracted far more pollinators than those of the present, according to the study.
“It seems that it’s only traits (特性) that are involved in plant-pollinator interaction that are evolving, ” said Acoca-Pidolle. The changes could restrict the plants’ ability to adapt to future environmental changes and have implications for “all of floral biodiversity” — potentially decreasing flowering plants’ genetic, species and ecosystem variation.
“This may increase the pollinator decline and cause a negative feedback cycle,” study coauthor Pierre-Olivier Cheptou told CNN.” If plants produce less nectar, there will be less food available to pollinators, which will in turn accelerate the rate at which the animals’ numbers decrease“, he explained.
“The major message is that we are currently seeing the evolutionary breakdown of plant pollinators in the wild,” said Cheptou, an evolutionary ecologist at the French National Centre for Scientific Research and professor at the University of Montpellier.

10 . When we recall a memory, we bring back specific details about it. But we often also experience a vivid feeling of remembering the event. Memory researchers call these processes objective and subjective memory. A new study shows they can function independently and involve different parts of the brain.
“The study distinguishes between how well we remember and how well we think we remember, and shows that decision making depends primarily on the subjective evaluation of memory evidence,” says psychologist Denis Guetta.
The researchers tested objective and subjective memory. After showing volunteers a series of images of common objects, the researchers showed them pairs of images and asked them to determine which of the two they had seen before. They were asked to rate the memory as “recollected” (vivid and detailed), or “familiar” (lacking detail). Some tests showed similar image pairs, others unrelated pairs. This setup measured objective memory based on recognition and subjective memory based on vividness.
The researchers also used fMRI (功能性磁共振成像) to measure brain activity during this task. The results showed higher levels of objective memory with pairs of similar images, but participants claimed vivid memories more with dissimilar pairs. They were more likely to base their decision about whether to keep or clear an image on memory feeling rather than accuracy. For example, a person could have a vivid memory of going to an event with friends. Some of the actual details of that memory might be a bit off, but they may feel it is a vivid memory, so they might decide to go out with the same people again.
The fMRI data showed that objective and subjective memory engaged varied regions of the brain. The regions involved in subjective experiences were also involved in decision making, supporting the connection between the two processes.
“By understanding how our brains give rise to vivid subjective memories and memory decisions, we are moving a step closer to understanding how we learn to evaluate memory evidence to make effective decisions in the future,” says researcher Analiz William.
