A new study investigated the molecular mechanisms underlying responses to sublethal thermal stress in aquatic #Daphnia by examining shifts in gene expression and fitness.
Find more in #G3journal about the pathways involved in the thermal stress response. buff.ly/kROeC6q
Spotted some Daphnia in a natural, non natural habitat today whilst doing some boaty bits in the dinghy park.

Coate, Ho & Schaack examine the patterns of spontaneous mutations in regions of low and high transcription in two species of Daphnia, finding that mutations are more frequently observed in regions of high transcription in both species.

Screenshot showing title "Historical exposure to artificial light at night shapes Daphnia responses: an experiment across and urban-rural gradient.
This looks like an interesting new paper: https://doi.org/10.1002/ece3.72624
It suggests that #daphnia in urban lakes have evolved in response to #LightPollution.
It would be great to see if this effect can be replicated in Europe and North America, and tested along a gradient.
@msumgi.bsky.social wrote a nice article about our paper too natsci.msu.edu/news/2025/20...

Circular logo with white silhouette of Daphnia and its ephippium. Daphnia is located in the upper half of the circle and is depicted with a black eye, represented by a small circle. The ephippium is placed in the lower half of the circle and contains two eggs, represented by black oval shapes. Ehpippium is depicted within a sediment layer with older (lighter) layers at the bottom and younger (darker) layers on top, hinting at the lake darkening. The daphnia and the sediment with the ephippium are separated by the name of the project "Hippicap" running through the middle of the circular logo. The background of the logo is filled by a gradient from blue on the left to brown on the right, representing the browning of the lake water over time.
A logo for the Hippicap project, which examines the process of lake darkening through time by researching ephippia - the resting eggs of zooplankton called Daphnia

New paper: #lightpollution suppresses diel migration in #Daphnia, but no detectable difference between urban and rural populations. rdcu.be/eNVwb
So no adaptation to light pollution? We discuss different plausible explanations for this lack of differentiation.

Water Fleas (Daphnia) are a type of Cladoceran Crustacean.
Sometimes they resemble flakes of gold in the sunlight.
They swim using their 2nd set of antennae.
The main concentrations were near the marginal vegetation. Yum fish food. #WaterFlea #Daphnia #Breckland #Norfolk #invertebrate #rivers 5/25
