“…Both Karlsson (1984) and Bovet (1960) suggest that sunlight disorientates bank voles, although this conflicts with the findings of another study (Mather and Baker, 1980) which showed that vision combined with olfaction were the major senses involved in navigation of up to 80m distance for both A. sylvaticus and M. glareolus. In the present study 71% of animals were translocated between 06.00 and 07.00 and the remaining 29% between 18.00 and 19.00.…”

Abstract. Over the last 50 years increasing fragmentation of habitats has occurred due to road building. Fragmenting a large population into smaller ones can have a negative effect on population demography. In England much small mammal habitat occurs in suburban and rural areas where the majority of roads are either single track or two lanes, and traffic density is light. This study investigated the effect of minor roads on the movements of two small mammals, the wood mouse (Apodemus sylvaticus) and bank vole (Myodes glareolus). Capture-Mark-Recapture was used to study movements beside and across rural roads of two different widths. The results suggest that even small roads less than 6metres wide, with relatively little traffic, do act as partial barriers for these small mammals, reducing their movement between habitats on either side of the road. It is evident that island populations are being created as a result of road construction, even access roads within nature reserves.

“…It is clear that mice can also rely on visual cues for action guidance and object recognition during various natural behaviors, including navigation (Harvey et al, 2009; Mather and Baker, 1980), escaping predators (Edut and Eilam, 2004), and optomotor head-tracking (Umino et al, 2008). It is possible that cortical areas such as AL are involved in estimating self-motion, due to the sensitivity of neurons in AL to very high-speed stimuli that would arise during locomotion.…”

SUMMARY The mouse is emerging as an important model for understanding how sensory neocortex extracts cues to guide behavior, yet little is known about how these cues are processed beyond primary cortical areas. Here, we used two-photon calcium imaging in awake mice to compare visual responses in primary visual cortex (V1) and in two downstream target areas, AL and PM. Neighboring V1 neurons had diverse stimulus preferences spanning five octaves in spatial and temporal frequency. By contrast, AL and PM neurons responded best to distinct ranges of stimulus parameters. Most strikingly, AL neurons preferred fast-moving stimuli while PM neurons preferred slow-moving stimuli. By contrast, neurons in V1, AL, and PM demonstrated similar selectivity for stimulus orientation but not for stimulus direction. Based on these findings, we predict that area AL helps guide behaviors involving fast-moving stimuli (e.g., optic flow), while area PM helps guide behaviors involving slow-moving objects.

The prey detection methods of 12 species of Carabidae and one species of Staphylinidae were investigated using video and orientation techniques. The species examined were Cicindela campestris, Cychrus caraboides, Carabus problematicus, C. violaceus, Calosoma maderae, Nebria complanata, Scarites abbreviates, Broscus cephaloles, Pterostichus madidus, P. melanarius, P. niger, Abax parallelepipedus and Staphylinus olens. All the species examined were seen to respond to prey upon contact (either by tactile or gustatory reception) during locomotor activity. Tests using orientation chambers showed that some of the species would orientate towards prey in the absence of contact. Some species orientated using vision (C. campestris, C. maderae, S. abbreviates, A. parallelepipedus). This was most frequent when tested with fast‐moving prey. In others, orientation towards prey occurred when olfactory cues were available (P. madidus, P. melanarius, P. niger and A.parallelepipedus). All of the species employing this method of prey detection belonged to the Pterostichini and it appears that the receptors involved are situated on the antennae. Although some species did not orientate towards prey in the absence of contact cues, some of these species were found to respond to slug mucus (C. caraboides, C. problematicus, C. violaceus and S. abbreviates). The receptors for this are probably situated on the terminal ends of the palps. The method of prey detection used is discussed in relation to the ecology of the species.
