Animals have to develop novel behaviours to adapt to anthropogenic activities or environmental changes. Fishing vessels constitute a recent feature that attracts albatrosses in large numbers. While they provide a valuable food source through offal and bait, they cause mortalities through bycatch, such that selection on vessel attraction will depend on the cost-benefit balance.

- - Fucoxanthin is a valuable pigment from brown algae recognized for its bioactive properties and potential health benefits, with current research focusing on its functions and applications.
- - The cultivation of specific algae responsible for high fucoxanthin yields is influenced by light intensity, which is crucial for maximizing both biomass growth and pigment content.
- - Eco-friendly extraction methods like bio-based solvents and advanced chromatography techniques are highlighted as promising for future fucoxanthin production, with Asian companies leading the market, particularly in macroalgae production.
Article Synopsis
- The study identifies differences in classification within the Chromista, proposing a new family structure that includes groups for haptophytes, diatoms, and seaweeds.
- The Fucoxanthin and Chlorophyll-binding Protein (FCP) family consists of 52 genes and features complex pigment binding sites on Lhcf protein monomers, which typically bind multiple molecules of chlorophyll and fucoxanthin.
- RNA-seq analysis during controlled experiments showed that gene expression decreased with nitrogen depletion, with certain genes being expressed only at night for protective functions against sudden light exposure after dark periods.
Human joint action seems special, as it is grounded in joint commitment-a sense of mutual obligation participants feel towards each other. Comparative research with humans and non-human great apes has typically investigated joint commitment by experimentally interrupting joint actions to study subjects' resumption strategies. However, such experimental interruptions are human-induced, and thus the question remains of how great apes naturally handle interruptions.

However, joint commitment is not only a mental state but also a that reveals itself in the coordination efforts deployed during entry and exit phases of joint action. Here, we investigated the presence and duration of such phases in = 1,242 natural play and grooming interactions of captive chimpanzees and bonobos.
