Caring for newborn offspring hampers resource acquisition of mammalian females, curbing their ability to meet the high energy expenditure of early lactation. Newborns are particularly vulnerable, and, among the large herbivores, ungulates have evolved a continuum of neonatal antipredator tactics, ranging from immobile hider (such as roe deer fawns or impala calves) to highly mobile follower offspring (such as reindeer calves or chamois kids). How these tactics constrain female movements around parturition is unknown, particularly within the current context of increasing habitat fragmentation and earlier plant phenology caused by global warming. Here, using a comparative analysis across 54 populations of 23 species of large herbivores from 5 ungulate families (Bovidae, Cervidae, Equidae, Antilocapridae and Giraffidae), we show that mothers adjust their movements to variation in resource productivity and heterogeneity according to their offspring’s neonatal tactic. Mothers with hider offspring are unable to exploit environments where the variability of resources occurs at a broad scale, which might alter resource allocation compared with mothers with follower offspring. Our findings reveal that the overlooked neonatal tactic plays a key role for predicting how species are coping with environmental variation.

The diversity of bats in Ethiopia comprises at least 80 species, among them the Ethiopian long-eared bat that was described in 2000. It is most likely endemic to the highlands of Ethiopia. However, knowledge of the distribution of the species is limited. During a bat survey in 12 regions of central Ethiopia stretched over 700 km along the Ethiopian Rift, we trapped long-eared bats at sites in three regions and confirmed the species' identity by molecular analysis. All occurrence sites of P. balensis were above 2500 m, confirming this taxon as a high-altitude species. Two of the regions are additions to the known range of P. balensis but it is most likely present in more high-altitude areas of Ethiopia than currently known. Additional surveys in so far unsampled areas are therefore indicated.

It is widely acknowledged that welfare states are important determinants of health in Europe through their mediation of the extent, and impact, of socio-economic positions on health. Arguably, immunisation from market dependencies in healthcare has been associated with core public values of the traditional welfare state and has thus been perceived important for achieving public goods such as social cohesion, equity, and people’s well-being. In recent years, we have seen a change in change in welfare states, where policies aimed at decommodifying the citizens by sheltering them from market dependency, have been supplemented and even replaced by the reverse trend of healthcare recommodification, where the role of markets has been strengthened and access to services through citizenship has been reduced. There is consequently a need for studies that investigate the specific welfare regime features that best contribute to the protection and promotion of the well-being of its citizens. Concentrating on the healthcare part of the welfare state, we analyse differences of subjective perceptions of well-being (self-rated health and happiness) between European countries, by examining how such perceptions are associated with selected indicators related to expenditure, financing, provision, institutional features, primary care orientation, and health decommodification. The paper utilises ten rounds of the European Social Survey (ESS), spanning 20 years and including more than 130,000 individuals from 21 countries. Using multilevel modelling and controlling for individual-level demographic and socio-economic variables, the results suggest that several of the system characteristics are relevant for subjective perceptions of well-being. Public healthcare coverage shows the strongest positive association, while indicators of public–private mix in financing and private provision of healthcare showed less significant results.
