Data from: High levels of interspecific gene flow in an endemic cichlid fish adaptive radiation from an extreme lake environment

Antonia G. P. Ford, Kanchon K. Dasmahapatra, Lukas Rüber, Karim Gharbi, Timothée Cezard & Julia J. Day
Studying recent adaptive radiations in isolated insular systems avoids complicating causal events and thus may offer clearer insight into mechanisms generating biological diversity. Here, we investigate evolutionary relationships and genomic differentiation within the recent radiation of Alcolapia cichlid fish that exhibit extensive phenotypic diversification, and which are confined to the extreme soda lakes Magadi and Natron in East Africa. We generated an extensive RAD data set of 96 individuals from multiple sampling sites and found...

Data from: High levels of genetic structure and striking phenotypic variability in a sexually dimorphic suckermouth catfish from the African Highveld

Jake Morris, Antonia G. P. Ford, Jarome R. Ali, Claire R. Peart, Roger Bills & Julia J. Day
Uncovering biological diversity to more accurately understand diversity patterns, and ultimately the processes driving diversification, is important not only from an evolutionary perspective but also a conservation perspective. This is particularly pertinent in Africa's rivers in which overall diversity, as well as how it arose, is poorly understood in comparison with lacustrine environments. Here we investigate population divergence in the sexually dimorphic suckermouth catfish species Chiloglanis anoterus (Crass, 1960) from the African Highveld, in which...

Data from: Eutherian morphological disparity across the end-Cretaceous mass extinction

Thomas John Dixon Halliday & Anjali Goswami
In the aftermaths of mass extinction events, during radiations of clades, and in several other evolutionary scenarios, there is often a decoupling of taxonomic diversity and morphological disparity. The placental mammal radiation after the end-Cretaceous mass extinction is one of the archetypal adaptive radiations, but the change in morphological disparity of the entire skeleton has never been quantified across this important boundary. We reconstruct ancestral morphologies of 680 discrete morphological characters onto dated phylogenies of...

Data from: A dynamic framework for the study of optimal birth intervals reveals the importance of sibling competition and mortality risks

Matthew G. Thomas, Daryl P. Shanley, Alasdair I. Houston, John M. McNamara, Ruth Mace & Tom B. L. Kirkwood
Human reproductive patterns have been well studied, but the mechanisms by which physiology, ecology and existing kin interact to affect the life history need quantification. Here, we create a model to investigate how age-specific interbirth intervals adapt to environmental and intrinsic mortality, and how birth patterns can be shaped by competition and help between siblings. The model provides a flexible framework for studying the processes underlying human reproductive scheduling. We developed a state-based optimality model...

Data from: Mental illness, poverty and stigma in India: a case control study

Jean-Francois Trani, Parul Bakhshi, Jill Kuhlberg, Sreelatha S. Venkataraman, Hemalatha Venkataraman, Nagendra N. Mishra, Nora E. Groce, Sushrut Jadhav & Smita Deshpande
Objective: To assess the effect of experienced stigma on depth of multidimensional poverty of persons with severe mental illness (PSMI) in Delhi, India, controlling for gender, age and caste. Design: Matching case (hospital)–control (population) study. Setting: University Hospital (cases) and National Capital Region (controls), India. Participants: A case–control study was conducted from November 2011 to June 2012. 647 cases diagnosed with schizophrenia or affective disorders were recruited and 647 individuals of same age, sex and...

Data from: The impact of HCV infection duration on HIV disease progression and response to cART amongst HIV seroconverters in the UK

Introduction: The effect of HCV infection on HIV disease progression remains unclear; the effect of HCV infection duration on HIV disease progression is unknown. Methods: We used data from a cohort of HIV seroconverters to investigate the effect of HCV infection duration on time from HIV seroconversion to CD4 <350cells/mm3, AIDS or death, censoring at the earlier of cART initiation or last clinic visit, adjusting for confounders and splitting data into follow up periods from...
