- A novel technique for the precise measurement of CO2 production rate in small aquatic organisms as validated on aeshnid dragonfly nymphs
Summary: In vitro and in vivo validation of a simple respirometry system for simultaneous measurements of oxygen consumption and carbon dioxide production rate, in small aquatic organisms (2 mg wet mass).
- Enhanced fertility and chill tolerance after cold-induced reproductive arrest in females of temperate species of the Drosophila buzzatii complex
Summary: Temperate but not tropical females of the Drosophila buzzatii complex under reproductive arrest improve fitness after cold acclimation. Such cold adaptation could contribute to spread temperate species into cooler environments.
- The ocelli of Archaeognatha (Hexapoda): functional morphology, pigment migration and chemical nature of the reflective tapetum
Summary: The ocelli of the jumping bristletail Machilis hrabei have a reflective tapetum containing xanthine crystals. The screening pigment in the photoreceptor cells migrates behind the tapetum upon dark adaptation.
- To crash or not to crash: how do hoverflies cope with free-fall situations and weightlessness?
Highlighted Article: The crash-avoidance performance of hoverflies in different visual environments suggests the existence of a multisensory control system based mainly on vision rather than gravity perception.
- Hemolymph metabolites and osmolality are tightly linked to cold tolerance of Drosophila species: a comparative study
Summary: Small increases in the abundance of compatible osmolytes improve osmotic balance and cold tolerance in Drosophila.
- Sexual dimorphism in the compound eye of Heliconius erato: a nymphalid butterfly with at least five spectral classes of photoreceptor
Summary: Female Heliconius erato butterflies have two UV-sensitive photoreceptors, but males only have one, and both sexes have a red-sensitive photoreceptor.
- Behavioural evidence for a visual and proprioceptive control of head roll in hoverflies (Episyrphus balteatus)
Summary: Tethered flying hoverflies shed new light on a proprioception role to stabilize the body roll.
- CaMKII knockdown affects both early and late phases of olfactory long-term memory in the honeybee
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.
