For most species, it is currently not known whether individual characteristics and population parameters affecting dispersal distances within the local population are also affecting dispersal of individuals emigrating longer distances. We evaluated this in the great reed warbler Acrocephalus arundinaceus by analysing data of natal dispersal distances within (1) the local hatching area in southern
The book compares and contrasts the experiences of Finland and Sweden, then adopts an international perspective, encompassing the experiences of Asia, Latin America, Denmark and Norway. Lessons from the 1990s crisis are drawn, and possible solutions prescribed. The conclusion is that long-term effects of financial crises – financial liberalization and integration – are not as dramatic as the short
We studied Great Reed Warblers Acrocephalus arundinaceus at two localities in Ghana during the winter. In the north (Tono), the birds arrived from late September and conducted a rapid moult soon after arrival. Towards the end of moult, birds accumulated fat and disappeared from the site. In the south (Tafo), birds arrived from mid-November in fresh plumage. This seemed to be the final wintering ar
Song is a sexually selected trait in many bird species and has been suggested to function as a signal of a male's health and parasite resistance. Here we present an experimental field study on the long-term effects of parasite exposure early in life on adult bird song. We exposed nestling great tits (Parus major) to ectoparasitic hen fleas (Ceratophyllus gallinae) and on their recruitment into the
The primary (acute) haemosporidian infection has the greatest negative effect on an individual’s fitness. Weak individuals are most likely eliminated from the population, while those that survive, develop a chronic infection when parasite infection intensity is kept at low levels with minor effects on the condition of the host’s life history traits. It is still unknown whether low levels of haemos
Based on a novel dataset of about 1150 time series, this study provides monthly economic activity estimates for 28 countries during the Great Depression. Due to their high frequency, the indices reveal that steady growth was far from universal even in the second half of the 1920s. Monetary and financial instability, agricultural crises, and labor conflict continued to plague economies around the g
Popular Abstract in English Parasites and their host organisms have engaged in a desperate battle over millions of years to evolve strategies that enable continued survival of their respective species. Parasites require some key metabolites to be able to survive and reproduce inside the host that often results in damage to host, while host organisms attempt to limit or prevent this damage by severHaemosporidia is a well-studied group of parasites, which infect mammals, reptiles and birds and use blood sucking vectors for their transmission. By conducting natural population studies and experimental infections, We have been able to detect and quantify Haemosporidia from avian blood to investigate how these pathogens affect their avian hosts. We have used life history data of two long-term lo
Self-recognition is a trait presumed to be associated with high levels of cognition and something previously considered to be exclusive to humans and possibly apes. The most common test of self-recognition is the mark/mirror test of whether an animal can understand that it sees its own reflection in a mirror. The usual design is that an animal is marked with a colour spot somewhere on the body whe

Objective: To estimate the cost-effectiveness of strategies to prevent spontaneous preterm delivery (PTD) in asymptomatic singleton pregnancies, using prevalence and healthcare cost data from the Swedish healthcare context. Methods: We designed a decision analytic model based on the Swedish CERVIX study to estimate the cost-effectiveness of strategies to prevent spontaneous PTD in asymptomatic wom
