Data from: Bushmeat genetics: setting up a reference framework for the DNA-typing of African forest bushmeatPhilippe Gaubert, Flobert Njiokou, Ayodeji Olayemi, Paolo Pagani, Sylvain Dufour, Emmanuel Danquah, Mac Elikem K. Nutsuakor, Gabriel Ngua, Alain-Didier Missoup, Pablo A. Tedesco, Rémy Dernat & Agostinho Antunes
The bushmeat trade in tropical Africa represents illegal, unsustainable off-takes of millions of tons of wild game – mostly mammals – per year. We sequenced four mitochondrial gene fragments (cyt b, COI, 12S, 16S) in >300 bushmeat items representing nine mammalian orders and 59 morphological species from five western and central African countries (Guinea, Ghana, Nigeria, Cameroon and Equatorial Guinea). Our objectives were to assess the efficiency of cross-species PCR amplification and to evaluate the...
Bird habitat preferences are related to habitat type and disturbance in the Owabi Wildlife Sanctuary, Ashanti Region (Ghana)Collins Ayine Nsor, Nana Afua Dei Ankomah, John Mensah Nkrumah, Rockson Acolatse & Emmanuel Danquah
Context: Globally, an estimated 1.3% of the bird population has gone extinct over the last millennia largely due to loss of habitat preferences. Aims: This short-term study investigated disturbance-related drivers as predictors of bird habitat selection and assemblages in the Owabi Ramsar wetland. Methods: The study was carried out over a five-month period (May to September 2019), in four habitat types (farmlands, Built-up, forest reserve, and open water area). Data was collected in 84 plots...

Clearcutting and selective logging have inconsistent effects on liana diversity and abundance but not on liana–tree interaction networksPatrick Addo-Fordjour & Isaac Afram
Understanding the effects of forest management on lianas and their interaction with trees is an important step towards effective forest management. Our study therefore aimed at quantifying the patterns of liana diversity and abundance, and liana-tree interaction network structure in response to logging disturbance in a moist semi-deciduous forest in Ghana. We sampled lianas (diameter at 1.3 m ≥ 1 cm) and their host trees (diameter at breast height ≥ 5 cm) in 90 20...
This dataset represents the raw data collected for a study of plant composition and diversity in a12.9 ha moist semi-deciduous forest in the urban landcape of Kumasi, the city capital of the Ashanti Region of Ghana. Since 1960, the forest ecosytem has been gazetted and managed as a botanic garden, known as the Kwame Nkrumah University of Science and Technology (KNUST) Botanic Garden, to preserve its rich flora for environmental education, research and recreation. The...
Data from: Task shifting interventions for cardiovascular risk reduction in low-and middle-income countries: a systematic review of randomized controlled trialsJoyce Gyamfi, Gbenga Ogedegbe, Jacob Plange-Rhule, Alisa Surkis, Diana Margot Rosenthal, Collins Airhihenbuwa, Juliet Iwelunmor & Richard Cooper
Objective: To evaluate evidence from published randomised controlled trials (RCTs) for the use of task-shifting strategies for cardiovascular disease (CVD) risk reduction in low-income and middle-income countries (LMICs). Design: Systematic review of RCTs that utilised a task-shifting strategy in the management of CVD in LMICs. Data Sources: We searched the following databases for relevant RCTs: PubMed from the 1940s, EMBASE from 1974, Global Health from 1910, Ovid Health Star from 1966, Web of Knowledge from...
Savannas are widespread in sub-Saharan Africa (SSA) and unarguably play major role in the global carbon balance. Extensive quantification of carbon stocks of the savannas in SSA will therefore contribute significantly to the global carbon budget in the era of climate change. In this study, we investigated the spatial distribution of carbon stocks of different soil fractions from the dominant tree species (Vitellaria paradoxa) of three forest reserves in the Guinea savanna of Ghana as...
Fixed or mixed? variation in tree functional types and vegetation structure in a forest-savanna ecotone in West AfricaGeorge K.D. Ametsitsi, Thomas Adjei-Gyapong, Vincent Logah, Jon Lloyd & Elmar M. Veenendaal
We analysed thirty-five 400-m2 plots encompassing forest, savanna and intermediate vegetation types in an ecotonal area in Ghana, West Africa. Across all plots, fire frequency was over a period of 15 years relatively uniform (once in 2–4 years). Although woodlands were dominated by species typically associated with savanna-type formations, and with forest formations dominated by species usually associated with closed canopies, these associations were non-obligatory and with a discrete non-specialized species grouping also identified. Across...
Objective: The objectives of this study were to measure the global impact of the pandemic on the volumes for intravenous thrombolysis (IVT), IVT transfers, and stroke hospitalizations over 4 months at the height of the pandemic (March 1 to June 30, 2020) compared with two control 4-month periods. Methods: We conducted a cross-sectional, observational, retrospective study across 6 continents, 70 countries, and 457 stroke centers. Diagnoses were identified by their ICD-10 codes and/or classifications in...
Data from: Health insurance coverage with or without a nurse-led task shifting strategy for hypertension control: a pragmatic cluster randomized trial in GhanaGbenga Ogedegbe, Jacob Plange-Rhule, Joyce Gyamfi, William Chaplin, Michael Ntim, Kingsley Apusiga, Juliet Iwelunmor, Kwasi Yeboah Awudzi, Kofi Nana Quakyi, Jazmin N. Mogavero, Kiran Khurshid, Bamidele Tayo & Richard Cooper
Rationale: Poor access to care and physician shortage are major barriers to hypertension control in sub-Saharan Africa. Implementation of evidence-based systems-level strategies targeted at these barriers are lacking. Objective: To evaluate the comparative effectiveness of provision of health insurance coverage (HIC) alone versus a nurse-led task-shifting strategy for hypertension control (TASSH) plus HIC on systolic BP reduction among patients with uncontrolled hypertension in Ghana. Methods and Findings: Using a pragmatic cluster-randomized trial, 32 community health...
Proximity to forest mediates trade-offs between yields and biodiversity of birds in oil palm smallholdingsKeith C Hamer, Michael A Sasu, Linda Ofosuhene, Rebecca Asare, Benjamin Ossom, Catherine L Parr, Sarah A Scriven, Winston Asante, Rosemary Addico & Jane K Hill
There is much debate about how best to mitigate the effects of agricultural expansion on biodiversity, especially in the tropics. Recent studies have emphasised that proximity to natural habitats can enhance farmland biodiversity, yet few studies have examined whether or not such proximity mediates local trade-offs between yields and biodiversity, and hence alters conclusions about the ecological benefits of alternative farming strategies. Here we examine yield-biodiversity trade-offs, focusing on birds in oil palm smallholdings at...
Responses of tropical tree seedlings in the forest-savanna boundary to combined effects of grass competition and fireHamza Issifu, Philippine Vergeer, George K. D.

Co-occurring tree functional types (TFTs) within forest-savanna transitions may differ in seedling responses to grass competition and fire in savannas. We performed a common garden experiment in the Guinea savanna of Ghana to test hypotheses related to competition effects on growth, allocation to root storage reserves and subsequent survival responses to dry season fire for savanna-transitional TFT (i.e., species occurring both in forest and savanna) and forest TFT. The experiment included factorial combinations of TFT,...
