'What Does the Anemonefish Say?': Investigating <i>Amphiprion percula</i>'s Acoustic Behaviour. [PDF]
Ecol EvolThis study investigates the vocal behaviour of wild Amphiprion percula in Papua New Guinea, revealing that distinct acoustic signals correspond to specific social interactions and are influenced by behaviour and rank. The findings underscore the importance of in situ research for understanding fish communication and highlight potential disruptions from

Amphibian Chytrid Fungus Infection Influences Calling Investment in Male Brown Toadlets. [PDF]
Ecol EvolThe sublethal effects of infection and disease on male advertisement behaviour remain poorly understood. Here we show that male brown toadlets infected with the amphibian chytrid fungus produce calls with more pulses compared to uninfected males. The association we report supports the terminal investment hypothesis and has the potential to impact host ...

Mathematical Modeling of Linear Fractional Oscillators
Mathematics, 2020 In this work, based on Newton’s second law, taking into account heredity, an equation is derived for a linear hereditary oscillator (LHO). Then, by choosing a power-law memory function, the transition to a model equation with Gerasimov–Caputo fractional ...

The RC Network Analyzer Using the High Permittivity Ceramics and its Applications [PDF]
, 1966 Described in this paper are the design considerations of the simple element of the two-dimensional RC distributed constant circuit and its applications for the analysis of the transient heat conduction problems in engineering work. This element is formed

Allometric Constraint Predominates Over the Acoustic Adaptation Hypothesis in a Radiation of Neotropical Treefrogs. [PDF]
Integr ZoolMale frogs emit calls to attract mates and deter conspecific rivals. The evolution of these calls is thought to be linked to anatomical constraints and the acoustic characteristics of their surroundings. We tested these two factors in a radiation of 112 species of Neotropical treefrogs and found that body size and calling site affect peak frequency but
