- In Focus: Reichert, S., Berger, V., Jackson, J., Chapman, S. N., Htut, W., Mar, K. U., & Lummaa, V. (2019). Maternal age at birth shapes offspring life-history trajectory across generations in long-lived Asian elephants. Journal of Animal Ecology, 89, 996-1007. Parental age can have strong effects on offspring life history, but the prevalence and magnitude of such effects in natural populations remain poorly understood. Using a multigenerational dataset of semi-captive Asian elephants, Reichert et al. (2019) studied the effects of maternal and grandmaternal age on offspring performance and found that offspring from old mothers have lower survival, but higher body condition and reproductive success than offspring from younger mothers. Importantly the observed consequences on survival are long-lasting and span more than one generation, with grand-offspring of old grandmothers also showing reduced survival. These findings suggest that persistent transgenerational effects of maternal age on fitness can shape the individual variation in ageing patterns in nature and ultimately the evolution of life histories.

- Recent research suggests that effects of species loss on the structure and functioning of ecosystems willcritically depend on the order with which species go extinct. However, there are few studies of theresponse of natural ecosystems to realistic extinction sequences. Using an extinction scenario basedon the International Union for Conservation of Nature (IUCN) Red List, de Visser et al. sequentiallydeleted species from a topological model of the Serengeti food web. Under this scenario, large-bodiedspecies like top predators and mega-herbivores go extinct first. The resulting changes in the trophicstructure of the food web might affect the robustness of the ecosystem to future disturbances.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- 1. Pre-breeding survival, i.e. survival from fledging up to the third winter, of barnacle geese (Branta leucopsis) was analysed by using more than 45 000 resightings of 1302 individually marked birds. Since observations from the wintering areas only were
