Summary: Here, we link the pivotal discoveries in respiratory control in fishes to the development of innovative methods and posit that the adoption of gene-based technologies will be instrumental in advancing the field.
Editor's choice: Drosophila descending neurons respond to visual looming information from the contralateral eye, even though their dendrites are ipsilateral, highlighting the importance of bilateral visual integration in generating location-invariant escape responses.
METHODS & TECHNIQUES
Summary: A machine learning-based method for reconstructing the pressure field around swimming fish can be used to study the role of pressure sensing in a fish’s response to external stimuli.
To escape or to pursue: opposite decision making concerning a single moving object is influenced by starvation and sex
Summary: In the crab Neohelice granulata, compatible decisions between prey catching or predator escape responses are elicited by the same moving object. The behavioural choice depends on starvation level and sex.
How bumblebees coordinate path integration and body orientation at the start of their first learning flight
Summary: Bumblebees fixate the nest while viewing a preferred location in their visual surroundings. This conjunction is aided by a preceding translational scan.
Highlighted Article: Environmentally found sublethal doses of fipronil affect cockroach exploratory behavior and olfactory memory, similar to the effect on honey bees.
Elevated developmental temperatures impact the size and allometry of morphological traits of the bumblebee Bombus terrestris
Summary: Bumblebees show a reduction in body size and antenna length and a change in allometric scaling of the tongue with elevated developmental temperature, indicating a strong impact of temperature on morphological traits.
Highlighted Article: Vertical and mediolateral limb loading patterns suggest that there are multiple strategies of body weight support and locomotor stability across suspensory mammals.
Aversive memory conditioning induces fluoxetine-dependent anxiety-like states in the crab Neohelice granulata
Summary: Crab associative aversive conditioning leads to the formation of enduring emotional behavior, revealed through dark/light plus-maze evaluation, involving serotonin-dependent processes.
Balanced mitochondrial function at low temperature is linked to cold adaptation in Drosophila species
Summary: Mitochondrial oxygen consumption decreases at low temperature, particularly in cold-sensitive Drosophila species, which turn to oxidation of alternative substrates as complex I-supported respiration is impaired.
Summary: Efficient neurotransmission supported by increased sphingomyelin and reduced glutamate levels, as well as increased glycolytic capacity, may contribute to the hypoxia tolerance of the pinniped brain.
