Preterm Birth Initiative-Rwanda group antenatal care providers focus group discussions, qualitative data

Tiffany Lundeen, Elizabeth Butrick, Dilys Walker, Hana Azman, Sabine Musange, David Nzeyimana & Nathalie Murindahabi
Background: The East Africa Preterm Birth Initiative-Rwanda began a cluster randomized controlled trial of group antenatal care (ANC) and postnatal care (PNC) in Rwanda in 2017. That trial will report its primary outcome, gestational length at birth, after data collection concludes in 2019. This nested study includes providers of ANC and/or PNC at the 18 health centers randomized to provide the group model of ANC/PNC and the 18 health centers randomized to continue providing ANC/PNC...

Data from: Carbon stocks and dynamics at different successional stages in an Afromontane tropical forest

As a result of different types of disturbance, forests are a mixture of stands at different stages of ecological succession. Successional stage is likely to influence forest productivity and carbon storage, linking the degree of forest disturbance to the global carbon cycle and climate. Although tropical montane forests are an important part of tropical forest ecosystems (c. 8 %, elevation > 1000 m a.s.l.), there are still significant knowledge gaps regarding the carbon dynamics and...

Fruit-feeding butterflies of Nyungwe National Park, Rwanda

Jean De Dieu Uwizelimana
A study was conducted in Nyungwe National Park, Rwanda from October 2019 to August 2020. The study aimed at documenting the diversity and distribution of fruit-feeding butterflies across an elevation gradient in Nyungwe National Park. Sampling was conducted seasonally using fruit-bated traps. Higher species richness was documented at low altitudes and decline with increasing elevation.

Global biogeography of warning colouration in the butterfly Danaus chrysippus

Warning colouration provides a textbook example of natural selection, but the frequent observation of polymorphism in aposematic species presents an evolutionary puzzle. We investigated biogeography and polymorphism of warning patterns in the widespread butterfly Danaus chrysippus using records from citizen science (n=5467), museums (n=8864), and fieldwork (n=2586). We find that polymorphism in three traits controlled by known mendelian loci is extensive. Broad allele frequency clines, hundreds of km wide, suggest a balance between long-range dispersal...

Mercury accumulation in leaves of different plant types – the significance of tissue age and specific leaf area

Håkan Pleijel, Jenny Klingberg, Michelle Nerentorp, Malin Broberg, Brigitte Nyirambangutse, John Munthe, Göran Wallin & Malin C. Broberg
Mercury, Hg, is one of the most problematic metals from an environmental perspective. To assess the problems caused by Hg in the environment it is crucial to understand the processes of Hg biogeochemistry, but the exchange of Hg between the atmosphere and vegetation is not sufficiently well characterised. We explored the mercury concentration, [Hg], in foliage from a diverse set of plant types, locations and sampling periods to study whether there is a continuous accumulation...

Group antenatal and postnatal care in Rwanda: model fidelity monitoring data

For a cluster randomized controlled trial of the effect of group antenatal care on perinatal outcomes in Rwanda, a Technical Working Group customized the group care model for implementation in this context. Group antenatal and postnatal care were implemented in 18 Rwandan health centers during the study period June 1, 2017 to January 31, 2019. We used two discreet questionnaires to collect data from two groups about the fidelity with which the group antenatal care...
