Evolution of acoustic communication in the Gomphocerinae (Orthoptera: Caelifera: Acrididae). — Zoologica Scripta, 40, 479–497. We used a phylogenetic analysis to study the communication behaviour in the Gomphocerinae (Insecta, Orthopte...

The CXXR project aims gradually to reengineer the fundamental parts of the R interpreter from C into C++ in such a way that: • the full functionality of the standard distribution of R (including the recommended packages) is preserved; • the behaviour of R code is unaffected (unless it probes into interpreter internals); • there is no change to the existing interfaces for calling out from R to o...

Numerous attempts have been made to quantify ecological factors that affect the calling range of animal signals. The various processes leading signals to become distorted and embedded in background noise have been described in many habitats (ranging from forest to savannah) and the propagation path in these biomes has thereby been characterized. However, the impact of climatic factors on acoust...

Unlike most Arti cial Life studies, we use biological data to verify a hypothesis about control mechanisms. We recorded male cricket Gryllus bimaculatus calling song, built a robot with the hypothesised control mechanism for phonotaxis behaviour and veri ed that it could account for the behaviour by observing the robot doing phonotaxis to the real cricket song. Further, we present a set of robo...

Occupational calling is a transcendent summons that originates externally to carry out a particular life role (work) in a manner that demonstrates meaningfulness and holds other-oriented values and goals as the main sources of motivation. The aim of the current study is to advance the study of individual differences in achieving occupational calling at workplace. Every individual varies in the ...

The adaptive function of copulation calls in female primates has been debated for years. One influential idea is that copulation calls are a sexually selected trait, which enables females to advertise their receptive state to males. Male-male competition ensues and females benefit by getting better mating partners and higher quality offspring. We analysed the copulation calling behaviour of wil...

In this report we present a rule-based approach to detect anomalous telephone calls. The method described here uses subscriber usage CDR (call detail record) data sampled over two observation periods: study period and test period. The study period contains call records of customers’ non-anomalous behaviour. Customers are first grouped according to their similar usage behaviour (like, average nu...

Neuroactive substances were administered into the frontal protocerebrum of tethered male Gryllus bimaculatus by pressure injections from microcapillaries. All three types of species-specific song pattern (calling song, rivalry song and courtship song) could be elicited by injection of acetylcholine and cholinergic agonists. Injection of nicotine led to short bouts of calling song that occurred ...
