Summary: This study found that Western Australian Magpies are able to distinguish between individuals within and outside of their social group based on territorial carolling calls, using only vocal signals.

Summary: This study examined the transition from female-like great calls to male-specific calls in young male gibbons, finding that they emit both types of calls between 5.6 to 7.1 years old before exclusively emitting male calls. The development of the male call, including mature multi-modulation phrases and staccato notes, is a normal part of aging process in juvenile gibbons.

Summary: Most bat species have equally good auditory sensitivity in both high- and low-frequency ranges, but amplitude is more finely coded for higher frequency ranges. Species-specific peaks in hearing sensitivity correlate with peak frequencies of echolocation calls and pup isolation calls.

Summary: AVT influences male responses to acoustic signals in Ttingara frogs, affecting motivation to call and production of vocalizations, but does not appear to alter the salience of frequency modulation in recognizing and responding to stimuli.

Summary: This study investigates the correlated evolution of wing morphology and echolocation calls in bats within a phylogenetic comparative framework. The results show that wing morphology and echolocation call parameters are dependent on families and exhibit a marked phylogenetic signal. There is a correlation between peak frequency, call duration, relative wing loading, and aspect ratio among different foraging guilds of bats. The findings suggest that the adaptive response to foraging ecology has shaped the correlated evolution between flight morphology and echolocation calls in bats.

Summary: Studies have shown that the sounds of animals can influence the behavior of receivers through nonlinear phenomena. This study focuses on the differential effects of different nonlinear phenomena in the calls of female Odorrana tormota on the vocal behavior of male frogs. The results reveal that calls with subharmonics elicit more short calls and answering calls from males, while calls with frequency jumps trigger more staccato calls. These findings provide a foundation for understanding the function of nonlinear phenomena in anuran vocalizations.

Summary: This study investigated the vocal performance of male and female European robins and found no significant differences between them. This suggests that song plays a similar role in territory defense and social competition for both sexes. Additionally, vocal performance was not correlated with morphometric measures or body condition.

Summary: Reproduction involves communication between males and females, with males evolving elaborate displays to attract females. The study on guinea pigs found that courtship calls may reflect male identity, but not dominance status. Further research may reveal the role of different communication channels in the courting process.

Summary: Researching sensory and cognitive adaptations in animals is crucial for understanding the evolution of adaptive behaviors, with bats being ideal animals due to their high ecological diversity. Recent studies have provided insights into the molecular, genetic, neural, and behavioral bases of sensory ecology and cognition in bats, revealing connections between information filtering, evolutionary trade-offs, and multimodal sensing. Investigating the selective pressures underlying information acquisition, processing, and use in bats aims to illuminate patterns and processes driving sensory and cognitive evolution.

Summary: The integration of life-history, behavioural and physiological traits into a 'pace-of-life syndrome' is a powerful concept in understanding trait variation in nature. This study investigated the relationship between pace-of-life and thermal performance in damselfly larvae. The results showed a trade-off between a faster pace-of-life and higher thermal performance, suggesting that the energetically costly maintenance of a fast pace-of-life may contribute to the variation in pace-of-life within populations.

Summary: This study investigated whether greater horseshoe bats can recognize the sex and individual identity of conspecifics from their echolocation calls alone. Through playback experiments, it was demonstrated that they can, indicating potential communication functions for their echolocation calls. These findings improve our understanding of bat echolocation calls as a form of communication.

Summary: Vocal recognition in social contexts is widespread and can be explained by kin and mate recognition or group coordination. Some species have evolved alarm calls that provide cues to signaller identity, potentially facilitating the detection of unreliable callers and supporting the idea of reputation-based mate choice.

Summary: The two main theories of food-associated calls in animals suggest either cooperative recruitment or competitive spacing. Sooty mangabeys do not have food calls but produce grunts during foraging. Grunt rates were significantly higher when subjects were foraging in the group's periphery and with small audiences, in line with the cooperative recruitment hypothesis.

Summary: Anther cuticle and pollen exine are two crucial lipid layers in plants that are important for normal pollen development and successful fertilization. The molecular mechanisms underlying the formation of these lipid layers have been unclear. In this study, we identified a maize mutant called pksb, which had a denser anther cuticle, thinner pollen exine, and delayed tapetal degeneration compared to the wild type. We found that the causal gene of the pksb mutant (ZmPKSB) encoded a polyketide synthase (PKS) that plays a role in lipid biosynthesis. The ZmPKSB gene was specifically expressed in maize anthers and was regulated by a transcription factor called ZmMYB84. Loss of function of ZmMYB84 resulted in similar phenotypes as the pksb mutant. The ZmMYB84-ZmPKSB regulatory module controlled the formation of the anther cuticle and pollen exine by regulating the expression of genes related to sporopollenin, cutin, and wax biosynthesis and transport. These findings provide new insights into the regulation of lipid metabolism in plants.

Summary: Stochastic thermodynamics has become a framework to study the thermodynamics of small-scaled systems. The relation between entropy production and precision is one of the most important research topics in this field. In this paper, the author investigates the amount of dissipation needed to follow a pre-determined trajectory and derives the trade-off relation between precision and dissipation. The optimal protocol for maximizing precision with a given amount of dissipation is also derived.
