Article Synopsis
  • This study investigates bisarsine oxides as new bridging ligands to create efficient luminescent lanthanide coordination polymers, specifically focusing on one-dimensional (1D) Europium (Eu) structures.
  • The synthesized coordination polymers display a denser chain arrangement and show excellent thermal stability, with strong emission quantum yields and a distinct polarization effect, leading to sharp red emissions.
  • Notably, the Eu coordination polymers maintain intense emissions at high temperatures (up to 550 K) and exhibit enhanced emission when heated from 300 K to 400 K.

Tandem running in ants is a sophisticated form of communication. Precise measurement of movement coordination by the tandem pair can shed light on social interactions. Here, we describe an integrative approach to obtain long movement trajectories of a specific tandem pair within a crowd of ants.

Communication is fundamental to the organization of animal societies, often resulting in the convergent evolution of similar social behavior across lineages. However, this similarity may conceal underlying functional and mechanistic differences. Here we combined network and information-theoretic analysis to quantify how tandem recruitment is distinguishable between two ant genera, and .

The positive association between disturbances and biological invasions is a widely observed ecological pattern in the Anthropocene. Such patterns have been hypothesized to be driven by the superior competitive ability of invaders or by modified environments, as well as by the interaction of these factors. An experimental study that tests these hypotheses is usually less feasible, especially in protected nature areas.

Background: Division of labour (DOL) is ubiquitous across biological hierarchies. In eusocial insects, DOL is often characterized by age-related task allocation, but workers can flexibly change their tasks, allowing for DOL reconstruction in fluctuating environments. Behavioural change driven by individual experience is regarded as a key to understanding this task flexibility.
