Phylogenetically-controlled correlates of primate blinking behaviour

چکیده

Eye blinking is an essential maintenance behaviour for many terrestrial animals, but also a risky as the animal unable to scan environment and detect hazards while its eyes are temporarily closed. It therefore likely that length of time closed gap between blinks species may reflect aspects ecology species, such social or physical environment. An earlier published study conducted comparative linking ecology, detailed dataset describing large number primate was collected from captive analysis presented did not control nonindependence data due common evolutionary history. In present study, reanalysed using phylogenetic methods, after reconsideration parameters environments species. I find blink rate best described by locomotion mode where moving through arboreal least, ground-living most, use both show intermediate rates. The duration related mode, positively correlated with mean group size body mass, although increase in relation small. How moves appears be important determining behaviour, suggests complex require less interruption visual attention. Given were individuals, caution recommended interpreting correlations found.

Asian Primate Species Richness Correlates with Rainfall

Previous studies of meta-analyses found significantly positive correlations between primate species richness and rainfall for Africa, Madagascar and the Neotropics, with the exception of Asia, leaving the open question whether that anomaly is the result of sampling bias, biogeography, or some other factor. This study re-examines the question using modelled data, with primate species richness da...

Moderate evidence for a Lombard effect in a phylogenetically basal primate

When exposed to enhanced background noise, humans avoid signal masking by increasing the amplitude of the voice, a phenomenon termed the Lombard effect. This auditory feedback-mediated voice control has also been found in monkeys, bats, cetaceans, fish and some frogs and birds. We studied the Lombard effect for the first time in a phylogenetically basal primate, the grey mouse lemur, Microcebus...

Neural correlates of short-term memory in primate auditory cortex

Behaviorally-relevant sounds such as conspecific vocalizations are often available for only a brief amount of time; thus, goal-directed behavior frequently depends on auditory short-term memory (STM). Despite its ecological significance, the neural processes underlying auditory STM remain poorly understood. To investigate the role of the auditory cortex in STM, single- and multi-unit activity w...

Understanding Eocene primate palaeobiology using a comprehensive analysis of living primate ecology, biology and behaviour

The comparative method is central to interpretations of Eocene primate palaeobiology. This method rests upon a thorough study of analogous living forms. With a rapidly increasing knowledge of such forms, most notably the Malagasy lemurs, our ability to advance the study of Eocene primate ecology, biology and behaviour far exceeds that of even just a few years ago. Here we present such a compari...

Neural correlates of eye blinking; improved by simultaneous fMRI and EOG measurement.

Neural correlates of eye blink in healthy human subjects can be investigated using functional magnetic resonance imaging. However, the focus of most previous studies has been on intentional eye blinking. The goal of the present study was to examine the neural correlates of spontaneous eye blinking with the help of EOG measurements during data acquisition of fMRI. After the removal of the pulse ...
