In many mammals, breeding females are intolerant of each other and seldom associate closely but, in some, they aggregate in groups that vary in size, stability, and kinship structure. Aggregation frequently increases competition for food, and interspecific differences in female sociality among mammals are commonly attributed to contrasts in ecological parameters, including variation in activity timing, the distribution of resources, as well as the risk of predation. However, there is increasing indication that differences in female sociality are also associated with phylogenetic relationships and with contrasts in life-history parameters. We show here that evolutionary transitions from systems where breeding females usually occupy separate ranges ("singular breeding") to systems where breeding females usually aggregate ("plural breeding") have occurred more frequently in monotocous lineages where females produce single young than in polytocous ones where they produce litters. A likely explanation of this association is that competition between breeding females for resources is reduced where they produce single young and is more intense where they produce litters. Our findings reinforce evidence that variation in life-history parameters plays an important role in shaping the evolution of social behavior.Conspicuous male signals often play an important role in both attracting mates and deterring rivals. In territorial species with extrapair mating, female and male forays to other territories may be an important component underlying female choice and male mating success and might be influenced by male advertisement signals. Yet, whether off-territory foraying is associated with male signals is still not well understood. Here, we tested how female and male forays are associated with short-range visual and long-range acoustic signals (dawn song). We used an automated radio tracking system to follow the movements of wild great tits (Parus major) to other territories in relation to male dawn song, plumage ornaments, and extrapair paternity. We show that both sexes frequently forayed into others' territories throughout the breeding period. Movements of both males and females were associated with male song but not with plumage ornaments. Contrary to our expectations, females stayed away from territories where males sang elaborately, whereas males were attracted to those territories. Moreover, neither female nor male forays were associated with the occurrence of extrapair offspring. Our results, thus, suggest that, although forays into other territories are associated with male dawn song, females may not be attracted and males not repelled by dawn song. PD173074 This sheds a different light on the sex-specific effects of male advertisement signals, expanding the view on the selection pressures shaping such communication systems. In view of restrictions on patients because of COVID-19 pandemic, face-to-face consultations are difficult. This short commentary tells us about the feasibility of telemedicine in this scenario in obstetrics and gynaecology. The database from our teleconsultation application (Apollo 247 and Askapollo) was analysed to assess feasibility of telemedicine and to design a triage pathway to reduce hospital visits for non-emergency situations and also to identify emergency cases without delay during this lockdown phase. Existing guidelines by Ministry of Health and Family Welfare (MOHFW), Government of India, were accessed. This was a single-doctor experience of 375 consultations done over 65 days. We also designed a triage pathway for obstetrics and gynaecology cases, and we discussed general practice for obstetricians and gynaecologists with its utility and limitations. Telemedicine has provided us the opportunity to manage women health problems and pregnancy concerns during this pandemic of COVID-19, except a few instances where face-to-face consultation or hospital visi
