Summary: Changes occur in the transcription and translation of two pro-coagulant genes, coagulation factor II and fibrinogen gamma chain, in the liver of the African lungfish Protopterus annectens during three phases of aestivation.

Summary: Allometric studies of Physarum polycepharum reveal the existence of not only scaling law in locomotion speed, cell shape and intrinsic rhythm but also non-scalable rhythm components related to formation of the entire cell shape.

Highlighted Article: Pupfish acclimated to warm but ecologically relevant temperatures experience extended periods of anaerobism despite the availability of ambient oxygen.

Summary: Nitric oxide, a gaseous neurotransmitter, plays a modulatory role in controlling breathing in zebrafish during acute changes in environmental oxygen levels, and its role changes throughout development.

Summary: Anoxia exposure of the excised Pacific hagfish heart causes an immediate decrease in metabolic activity but this fully recovers during the subsequent 6 h of anoxia.

Highlighted Article: Air is much richer in oxygen than water, but surfacing to gulp air can require boldness in the air-breathing catfish.

Summary: Indian peafowl use eye and head movements to shift their gaze but, unlike mammals, they do not rely on the vestibulo-ocular reflex to stabilize their gaze.

Summary: Tethered flying hoverflies shed new light on a proprioception role to stabilize the body roll.

Summary: CaMKII inhibition and knockdown disrupts both early and late phases of olfactory long-term memory in the honeybee but leaves acquisition and MTM intact.

Highlighted Article: Dietary aspartic acid, asparagine, glutamic acid and glutamine are catabolized and re-synthesized in metabolic pathways for the synthesis of other amino acids in the aphid-Buchnera system.

Summary: This study shows that haemolymph loss and energy metabolism combine to affect the ability of insects to maintain discontinuous gas exchange cycles under stressful conditions.

Summary: A step-wise filtering method to detect buoyancy changes in drift diving pinnipeds.

Highlighted Article: Mesocosm observations on the reproduction of the squid Todarodes pacificus reveal the animal's spawning behavior, egg mass properties and paralarval development in a simulated natural environment.

Summary: Guineafowl running on treadmills and trackways often yaw from their direction of travel; this deviation is reflected by the limb kinematics, wherein femora synchronously rotate about their long axes to skew limbs mediolaterally through the stride cycle.

Summary: The odour plume-tracking ability of silkmoths is enhanced by visually guided osmotropotaxis combined with pre-programmed behaviour.

Summary: Elevated daylight activity of female Drosophila suzukii (spotted-wing Drosophila) is a post-mating response.
