Directional tuning of three unclassified neurones to drifting sine wave gratings (A, C and E) and 90° plaids (B, D and F). Conventions as in Fig. 3. Note that none of the partial correlation values are marked with an asterisk because for unclassified neurones such values do not reach statistical significance.

... most of the direction-selective neurones that we sampled within the visual wulst showed a CDS profile to drifting plaids, several of them did not concur with either component or pattern prediction. Figure 4 exemplifies three different reasons why this occurred. The unit in Fig. 4A and B illustrates the case of several neurones broadly tuned for gratings that were unclassifiable because their responses to plaids, although clearly directional, were somehow intermediate between the component and pattern predictions. ...

The unit in Fig. 4A and B illustrates the case of several neurones broadly tuned for gratings that were unclassifiable because their responses to plaids, although clearly directional, were somehow intermediate between the component and pattern predictions. The example in Fig. 4C and D illustrates another type of unclassified cell that had an attenuated response to plaids, without any clear unidirectional or bidirectional response profile. The behaviour of the cell in Fig. 4E and F was rather atypical. This unit was highly directional (DI ¼ 1.06) and broadly tuned (bandwidth, BW ¼ 49.16) for the gratings. In ...

The behaviour of the cell in Fig. 4E and F was rather atypical. This unit was highly directional (DI ¼ 1.06) and broadly tuned (bandwidth, BW ¼ 49.16) for the gratings. In response to plaids, it showed two clear peaks at angles corresponding to each of the components of the plaids. However, it failed to be classified as CDS because its plaid tuning curve was rotated ...

Aim Land use change, climate change, and shifts to disturbance regimes make successful wildlife management challenging, particularly when ongoing urbanization constrains habitat and movement. Preserving and maintaining landscape connectivity is a potential strategy to support wildlife responding to these stressors. Using a novel model framework, we...

Advances in bio-logging technology for wildlife monitoring have expanded our ability to study space use and behavior of many animal species at increasingly detailed scales. However, such data can be challenging to analyze due to autocorrelation of GPS positions. As a case study, we investigated spatiotemporal movements and habitat selection in the...

Individuals within populations often show consistent variation in behavioural and physiological traits which are frequently inter-correlated, potentially leading to phenotypic integration. Understanding the mechanisms behind such integration is a key task in evolutionary ecology, and melanin based colouration has been suggested to play a pivotal ro...

Joint species distribution models (JSDMs) are a recent development in biogeography and enable the spatial modelling of multiple species and their interactions and dependencies. However, most models do not consider imperfect detection, which can significantly bias estimates. This is one of the first papers to account for imperfect detection when fit...
