Adult male and female platypuses were radio-tracked in summer and winter at Lake Lea, north-western Tasmania. They appeared to exhibit greater diurnality, particularly during winter months, a greater degree of overland movement and more frequent use of non-earth refuge sites than do animals inhabiting mainland water bodies. Individuals foraged continuously for up to 16 h, with longer foraging bouts observed during the winter tracking period. Foraging range varied between 2 and 58 ha, with no significant differences observed between the sexes or seasons. All platypuses foraged predominantly in the lake; however, a number of animals were observed moving overland to and from waterbodies and burrows. Burrows were located on lake, creek and pool edges. A high percentage of burrows (25%) were located within dense sedge tussocks and scrub vegetation. Both the terrestrial activity and more opportunistic burrow-site selection may be related to reduced predation pressure in Tasmania.

Activity of Swift Foxes (Vulpes velox) at den sites was studied in northwestern Texas during pup rearing seasons in 2000 and 2001 to determine role of males in parental care. Twenty-four percent of radio-collared females with a potential to breed successfully raised pups to eight weeks of age. We intensively monitored presence and absence of male and female Swift Foxes at two den sites each year. Females were present >2.6 times more at den sites than males during the pup rearing season. Female and male Swift Foxes largely stayed at dens during diurnal hours and were active away from dens during nocturnal and crepuscular hours. Females and males spent 12.4% and 3.0% more time at dens before pups emerged, than after pups emerged, respectively. Following depredation of one male parent, the female spent 29% less time at the den site. Decrease in time spent at the den by the female following loss of her mate suggested that loss of one parent might severely impact recruitment of Swift Foxes. Our observations indicated that intense Coyote (Canis latrans) depredation may severely impact pup-rearing success as well as the parental care within Swift Fox family groups.

The differences between patients and staff in the use of time and space on the ward were much greater than between different patient groups and different staff groups. Patients spent considerably more time involved in isolated behaviours, active and passive, and in mixed active behaviours, while staff spent more time in social activities and looking after ward routine. Also, patients spent a large percentage of their time in the bedrooms and very little in staff offices, while the staff spent a large percentage of time in the offices and very little in the bedrooms. However, differences between patient groups do exist — chronic patients were more likely to be involved in isolated passive behaviours and spend a larger percentage of time in the bedrooms. Female active patients were more likely to be involved in isolated passive behaviours than male active patients, and were also more likely to be found in their bedrooms. Finally, male patients were liable to be involved in mixed activities, especially industrial therapy. Differences between the staff of different wards in the use of time and space were small — the staff of the female wards spent more time in the dining rooms while those of the chronic ward were usually involved in isolated passive behaviours. Differences between male and female staff were similar to differences between male and female patients. Female staff spent more time in their own ‘territory’ (the staff offices) and they were more often observed in isolated passive behaviour. Male staff were more likely to be involved in mixed activities with patients, especially industrial therapy. The activity patterns of the various locations were very similar across the wards although marked differences existed between staff and patients. Patients used bedrooms for isolated passive behaviours and staff used bedrooms for talking and routine. Staff were much more likely to use sitting rooms for social behaviour than were patients. Washrooms were used by both staff and patients for isolated active behaviours, such as reading.

Most studies focused on species coexistence have been directed at the differential use of habitat and food resources; nonetheless, the differential use of the diel cycle may enhance the coexistence of same-sized species. We investigated the activity patterns of mesocarnivores (red fox (Vulpes vulpes), European badger (Meles meles), pine marten (Martes martes), stone marten (M. foina)) in NW Italy via camera-trapping. We hypothesized that the smallest species would tend to avoid competition by selecting time periods when larger species were less active. Foxes, badgers, and stone martens were mainly nocturnal. In lowland areas overlap between coexisting species was generally low, while in Mediterranean habitats all activity patterns tended to be unimodal and overlap was generally high. The pine marten showed a cathemeral pattern. We suggest that the lower ability of the stone marten to avoid interference competition at community-level may play a major role in determining its widespread exclusion from forested areas by the pine marten.

Mating swarms of malaria mosquitoes form every day at sunset throughout the tropical world, they typically last less than 30 minutes. Activity patterns must thus be highly synchronized between the sexes. Moreover, males must be able to identify the few sporadically entering females by detecting the females' faint flight tones. We here show that the Anopheles circadian clock ensures a tight synchrony of male and female activity and - importantly - also retunes the males' acoustic detection system: by lifting their own flight tones at dusk, males actively enhance the audibility of females. The reported phenomenon of 'harmonic convergence' is a random by-product of the mosquitoes' flight tone variance. Intriguingly, flight tones of individual mosquitoes occupy narrow, partly non-overlapping, frequency ranges, suggesting that the audibility of individual females varies across males.

Touch is a fundamental aspect of mammalian social, parental and sexual behavior. Human affective touch is critical for healthy child development and shows great promise as a novel therapeutic strategy for mental disorders characterized by social dysfunction, such as anxiety, depression and autism spectrum disorder. However, despite our detailed knowledge about cortical processing of non-social touch, we still know very little about how social touch modulates cortical circuits. We investigated the activity patterns of single neurons (N = 1156) across five sensory and frontal cortical areas in both male and female rats (N = 28) engaging in naturalistic social facial touch with male and female conspecifics. We found that information about social touch is widely available across cortex. Besides touch, the sex of the interaction partner (a biologically significant feature) is a major determinant of single neuron activity, and across cortex we observed 25.7% ‘touch’ and 11.9% ‘sex-touch’ responses. Although all areas investigated had access to social touch and partner sex information, social touch modulated different cortical areas in different ways. Finally, we found that network activity patterns during social touch depend on both subject sex and partner sex. Interestingly, these sex-differences in network activity patterns were differences in response magnitude and would not be evident without single cell resolution. Our observations suggest that socio-sexual characteristics of touch (subject and partner sex) widely modulate cortical activity and need to be investigated with cellular resolution.
