Comparative performance of rural water supplies during drought - dataset

DJ. MacAllister, A.M. MacDonald, S. Kebede, S. Godfrey & R. Calow
Ethiopia experienced severe drought in 2015-16. Many rural communities experienced declines in the performance of their water supply systems. As a result UNICEF commissioned a real-time monitoring and responsive operation and maintenance programme for point source rural water supplies across Central, Northern and Eastern Ethiopia. The water point monitoring survey was coordinated by UNICEF and conducted by World Vision Ethiopia and Oxfam Ethiopia. Data was collected between January and May 2016. Akvo Flow, a mobile...

Phylogenomics and species delimitation for effective conservation of manta and devil rays

Emily Humble, Jane Hosegood, Rob Ogden, Mark De Bruyn, Simon Creer, Guy Stevens, Mohammed Abudaya, Kim Bassos-Hull, Ramon Bonfil, Daniel Fernando, Andrew Foote, Helen Hipperson, Rima Jabado, Jenny Kaden, Muhammad Moazzam, Lauren Peel, Stephen Pollett, Alessandro Ponzo, Marloes Poortvliet, Jehad Salah, Helen Senn, Joshua Stewart, Sabine Wintner & Gary Carvalho
Practical biodiversity conservation relies on delineation of biologically meaningful units. Manta and devil rays (Mobulidae) are threatened worldwide, yet morphological similarities and a succession of recent taxonomic changes impede the development of an effective conservation strategy. Here, we generate genome-wide single nucleotide polymorphism (SNP) data from a geographically and taxonomically representative set of manta and devil ray samples to reconstruct phylogenetic relationships and evaluate species boundaries under the general lineage concept. We show that nominal...

The functional ecology of bat pollination in the African sausage tree Kigelia africana (Bignoniaceae)

Ethan Newman, Keeveshnee Govender, Sandy Van Niekerk & Steven D. Johnson
Plants often interact with a wide range of animal floral visitors that can vary in their pollination effectiveness. Flowers of the African sausage tree Kigelia africana are be visited by bats and bush babies during the night and by birds during the day. We studied floral traits (phenophases, scent, colour and nectar chemistry) and the visitation frequency and pollination effectiveness of different flower visitors to determine if K. africana is functionally specialized for bat-pollination. We...

Cross-continental analysis of coastal biodiversity change

Helmut Hillebrand, Gavin M. Rishworth, Janine B. Adams, Matthew S. Bird, Nicola K. Carrasco, Andreas Dänhardt, Jennifer Dannheim, Daniel A. Lemley, Pierre A. Pistorius & Gregor Scheiffarth
Whereas the anthropogenic impact on marine biodiversity is undebated, the quantification and prediction of this change is not trivial. Simple traditional measures of biodiversity (e.g., richness, diversity indices) do not capture the magnitude and direction of changes in species or functional composition. In this paper, we apply recently developed methods for measuring biodiversity turnover to time-series data of four broad taxonomic groups from two coastal regions: the southern North Sea (Germany) and the South African...

Data from: Genome wide assessment of genetic variation and population distinctiveness of the pig family in South Africa

Nompilo L Hlongwane, Khanyisile Hadebe, Pranisha Soma, Edgar F Dzomba & Farai C Muchadeyi
Genetic diversity is of great importance and a prerequisite for genetic improvement and conservation programs in pigs and other livestock populations. The present study provides a genome wide analysis of the genetic variability and population structure of pig populations from different production systems in South Africa relative to global populations. A total of 234 pigs sampled in South Africa and consisting of village (n = 91), commercial (n = 60), indigenous (n = 40), Asian...

CLiP South Africa Marine Litter Accumulation Study (Cefas-UKZN) 2019

This dataset contains 2 csv files. The file South_Africa_Marine_Litter_Data.csv contains data on marine litter found during beach surveys in Umhlanga (north of Durban) and Amanzimtoti (south of Durban) in South Africa in September 2019. The number of items and the weight in kg is reported for each litter category. Each survey is named with the name of the location plus a capital letter between A and L for Amanzimtoti; and between A and K for...

Data from: Urbanization is associated with increased breeding rate, but decreased breeding success in an urban population of near-threatened African Crowned Eagles (Stephanoaetus coronatus)

Colleen Downs, Shane McPherson, Rebecca Muller, Petra Sumasgutner & Arjun Amar
Urban areas can be attractive to certain species because of increased food abundance and nesting availability which in turn may increase productivity or breeding rates. However, there are also potential costs associated with urban living such as higher nest failure, poorer body condition or increased prevalence of disease. These costs may result in species trading off the number of young produced against the condition of their young. African Crowned Eagles (Stephanoaetus coronatus) are a rare...

Groundwater recharge in Africa from ground based measurements

Alan MacDonald, Murray Lark, Richard Taylor, Tamiru Abiye, Helen Fallas, Guillaume Favreau, Ibrahim Goni, Seifu Kebede, Bridget Scanlon, James Sorenson, Moshood Tijani, Kirsty Upton & Charles West
This dataset comprises a map of groundwater recharge for Africa and a database of the 134 observations used to generate the map. The map shows long term average annual groundwater recharge in mm per annum relevant to the period 1970 to 2020. It is in the form of a GIS shapefile and is available as a layer package for ESRI and also as a georeferenced TIFF and BIL file for easy exchange with other software....

Does rapid utilisation of elevated nutrient availability allow eucalypts to dominate in the tropical savannas of Australia?

Harinandanan Paramjyothi, Brett Murphy, Michael Lawes, Natalie Rossitet-Rachor & Anna Richards
Northern Australia's savannas are amongst the most fire-prone biomes on Earth, and are dominated by eucalypts (Eucalyptus and Corymbia spp.). It is not clear what processes allows this group to dominate under such extreme fire frequencies and if a superior ability to compete for nutrients and water might play a role. There is evidence that eucalypts are adapted to frequent fires; juvenile eucalypts escape the fire trap by growing rapidly in height between fires. However,...
