Summary: This study explores how macaque cone photoreceptors maintain sensitivity under fast saccadic eye movements. The research shows that adaptation causes nonlinearity in cone responses to naturalistic stimuli, depending on stimulus history. A biophysical model can accurately predict cone responses to various stimuli.

Summary: The research shows that dietary restriction extends the lifespan of fruit flies by promoting rhythmic homeostatic mechanisms in the visual system. Altering the core molecular clock transcription factor CLOCK or its output genes accelerates visual aging and shortens lifespan. Photoreceptor activation shortens lifespan, while inactivation extends it.

Summary: An increasing number of studies are exploring circadian phase-shifting after exposure to millisecond light flashes, which, when combined with periods of darkness, can produce responses that rival or exceed those induced by steady luminance. A conceptual model is proposed in the study to connect the effects of flashes on the circadian system to the way the pacemaker intermittently samples photic information at dawn and dusk. This study also discusses the role of cones in predicting twilight for the pacemaker, suggesting that classical photoreceptors play a crucial role in the flash responses of ipRGCs.

Summary: This study aimed to develop a non-contact system based on an infrared webcam to measure event-related pupillary responses and obtain the amplitudes and latencies of event-related potentials. The results showed that this method can accurately measure changes in mental workload.

Summary: Behavioural disruptions can serve as sensitive indicators of abnormal animal physiology and are valuable for toxicity assessment. Zebrafish, a small vertebrate, is a commonly used model organism for toxicological studies. This study validates the use of an infrared-based Locomotor Activity Monitor (LAM) to assess zebrafish behaviour, and demonstrates the feasibility of using this method to evaluate multi parameter behavioural disruptions in zebrafish. The findings have broad applicability and may contribute to the development of standard methods for toxicity testing.

Summary: The study showed that different feeding protocols have an impact on the gut levels of cholecystokinin (CCK) and the activity of digestive enzymes in juveniles of Senegalese sole. The daily patterns of CCK and digestive enzymes varied depending on the feeding protocols, with digestive enzymes showing a correlation with CCK fluctuations.

Summary: This study investigated the behavioural activity changes of Anopheles coluzzii mosquitoes in different physiological states, revealing that insemination and blood digestion status can influence the rhythmic features of locomotor activity. In dim light conditions, inseminated females may exhibit sustained activity during the daytime, potentially impacting residual transmission of malarial parasites.

Summary: Individuals in multiple species display consistent timing of activity onset, which can be influenced by both intrinsic and extrinsic factors. This study found that 27% of the variation in activity onset in female great tits could be attributed to individual identity, while temporal and spatial environmental factors did not significantly contribute to the observed variation.

Summary: Immature individuals of Afrotridactylus cf. usambaricus were recorded on a marine sandy beach likely feeding on bacteria, microalgae, and mesopsammic organisms. They manipulate grains of sand to obtain these organisms and show a diurnal-tidal rhythm in migration, maintaining the sea-land direction even in a confined environment like a Plexiglas bowl.

Summary: This study assessed the toxic effect of super-paramagnetic iron oxide nanoparticles (SPIONs) on Labeo rohita fingerlings and the ameliorative effect of dietary vitamin E. Results showed that SPIONs altered haemato-immunological responses, oxidative stress, and metabolic enzyme activities in a dose-dependent manner. However, the toxicity of SPIONs could be partially mitigated by feeding vitamin E during the recovery period.

Summary: In recent decades, novel non-visual opsins have been identified and studied in the inner retina of vertebrates. These opsins play important roles in non-image-forming processes and can continue to function even in the absence of vision due to retinal degeneration. Other photopigments expressed in inner retinal neurons and Muller glial cells are also involved in chromophore recycling, retinal clock synchronization, neuron-to-glia communication, and other activities. The discovery of these new photopigments provides strong evidence for novel light-regulated activities.

Summary: This article reviews the reproductive biology of ratites, specifically focusing on the Challenge Hypotheses and the Challenge Hypothesis 2.0. Ratites, which are flightless and have promiscuous mating systems with male-only parental care, provide a unique perspective for studying the role of androgens in reproductive behavior. The lack of experimental approaches in behavioral endocrinology across ratites is also discussed. The review aims to inspire further research on this basal group of birds and enhance our understanding of the evolution of reproductive behavior in birds.

Summary: Molting is the process of replacing old feathers with new ones, and plumage color is determined by pigments and feather structure. However, there is limited research on the change in plumage color over time and its relationship to reproductive tasks. This study focuses on the Eared Dove and found a molting period of 6 months (January to June) with changes in feather coloration from July to December. The color variation in the crown feathers during the breeding season suggests a possible link to reproductive behaviors.
