Data from: A quantitative study of worker reproduction in queenright colonies of the Cape honey bee Apis mellifera capensis

Madeleine Beekman, Ben Oldroyd, Michael Allsopp, Alex Jordan & Julianne Lim
Reproduction by workers is rare in honey bee colonies that have an active queen. By not producing their own offspring and preventing other workers from producing theirs, workers are thought to increase their inclusive fitness due to their higher average relatedness towards queen-produced male offspring compared with worker-produced male offspring. But there is one exception. Workers of the Cape honey bee Apis mellifera capensis are able to produce diploid female offspring via thelytokous parthenogenesis and...

South African communal indigenous goats

Tlou Caswell Chokoe, Khanyisile Hadebe, Farai Muchadeyi, Edgar Dzomba, Khathutshelo Nephawe, Tumudi Mphahlele, Tlou Matelele & Bohani Mtileni
Indigenous goats form the majority of populations in smallholder; low input, low output production systems and are considered an important genetic resource due to their adaptability to different production environments and support communal farming. Effective population size (Ne), inbreeding levels, and the runs of homozygosity (ROHs) are effective tools for exploring the genetic diversity and understanding the demographic history in efforts to support breeding strategies to use and conserve genetic resources. Across populations, the current...

A data set was generated thorugh surveys to establish a baseline inforamtion for a project entitled "Innovations in Technology, Institutional and Extension Approaches towards Sustainable Agriculture and enhanced Food and Nutrition Security in Africa (Acronym - InnovAfrica)". The InnovAfrica is a consortium of 16 institutions comprising five institutions from Europe and eleven institutions from Africa and the project was implemented in six countries of eastern and southern Africa namely Ethiopia, Kenya, Malawi, Rwanda, South Africa...

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...

InnovAfrica project endline survey data for Ethiopia, Kenya, Malawi, Rwanda, South Africa and Tanzania

A consortium of 16 institutions comprising five institutions from Europe and eleven institutions from Africa implemented a project entitled "Innovations in Technology, Institutional and Extension Approaches towards Sustainable Agriculture and enhanced Food and Nutritional Security in Africa (InnovAfrica)" in six countries of eastern and southern Africa namely Ethiopia, Kenya, Malawi, Rwanda, South Africa and Tanzania from June 2017 to November 2021. The InnovAfrica project collected endline data from 12 pilot sites (two sites per country)...

Data from: Maternity of emergency queens in the cape honey bee, Apis mellifera capensis

Madeleine Beekman, Ben Oldroyd, Michael Allsopp, Theresa Wossler & Michael Holmes
During reproductive swarming, some workers of the Cape honey bee, Apis mellifera capensis, lay eggs in queen cells, many of which are reared to maturity. However, it is unknown if workers are able to lay in queen cells immediately after queen loss during an episode of emergency queen rearing. In this study we experimentally de-queened colonies and determined the maternity of larvae and pupae that were reared as queens. This allowed us to determine how...

Data from: Genetic diversification and dispersal of taro (Colocasia esculenta (L.) Schott)

Hana Chaïr, Renan E. Traore, Marie France Duval, Ronan Rivallan, Archana Mukherjee, Lawrence M. Aboagye, Willem J. Van Rensburg, Voahangy Andrianavalona, Miguel A.A. Pinheiro De Carvalho, Francisco Saborio, Made Sri Prana, Birte Komolong, Floriane Lawac & Vincent Lebot
Taro (Colocasia esculenta (L.) Schott) is widely distributed in tropical and sub-tropical areas. However, its origin, diversification and dispersal remain unclear. While taro genetic diversity has been documented at the country and regional levels in Asia and the Pacific, few reports are available from Americas and Africa where it has been introduced through human migrations. We used eleven microsatellite markers to investigate the diversity and diversification of taro accessions from nineteen countries in Asia, the...

Microsatellite data from various African buffalo (Syncerus caffer) populations throughout Africa

Pim Van Hooft, Wayne Getz, Ben Greyling, Rasmus Heller, Knut Røed & Armanda Bastos
1280 African buffalo (Syncerus caffer) samples genotyped with up to 19 microsatellites. 1275 samples are from East (12 populations) and southern Africa (4 populations). 5 samples are from central Africa (2 populations).

Innovafrica project data on agricultural food value chains

Chiara Perelli, Giacomo Branca, Luca Cacchiarelli, Donald Njarui, Esther Lupafya, Feyisa Hundessa, Joseph Hella, Mercy Mburu, Mokhele Moeletsi, Mufunanji Magalasi, Mupenzi Mutimura & Alessandro Sorrentino
A dataset was generated using the baseline survey data of the project entitled "Innovations in Technology, Institutional and Extension Approaches towards Sustainable Agriculture and enhanced Food and Nutrition Security in Africa (Acronym - Innovafrica)", which involved 16 istitutions from Europe and Africa and was implemented in six countries namely Ethiopia, Kenya, Malawi, Rwanda, South Africa and Tanzania. It includes the following information: smallholders' socio-demographic and economic characteristics; improved agriculture practices and seed systems adopted; climate...
