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.

Prisma checklist: Pharmacological management of seizures in patients with COVID-19: a systematic reviewPriscilla Mante, Nana Ofori Adomako, & Paulina Antwi
The PRISMA checklist provides information on the 27-item checklist indicating where data on the introduction, methods, results and discussion sections of the publication titled "Pharmacological management of seizures in patients with COVID-19: a systematic review" may be located in the manuscript. This checklist also covers information such as competing interests.
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...
Nowcasting (weather forecasting predictions from zero to several hours) has enormous value and potential in Africa, where populations and economic activity are highly vulnerable to rapidly changing weather conditions. Timely issuing of warnings, a few hours before an event, can enable the public and decision-makers to take action. Rainfall radar estimates are not widely available in Africa, nor likely to be in the coming years, and numerical weather prediction (NWP) currently has low skill over...
There is a huge opportunity for the African continent to benefit from the ‘silent revolution’ in weather forecasting that has been realised in the mid-latitudes throughout the twentieth century. While there are tremendous societal and economic benefits from advancing the science behind weather forecasting in sub-Saharan Africa, there are also significant barriers to realising advances. This policy brief examines the value of investment in African weather forecasting science and the technical & communication challenges that...

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,...
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...
