A morphometric and genetic investigation of Opuntia engelmannii population variation in Africa

Weed Research, Volume 62, Issue 5, Page 307-317, October 2022., 2022
Abstract Opuntia engelmannii Salm‐Dyck (Cactaceae:Opuntioideae) is a morphologically variable cactus that has invaded pasture lands in South Africa and Kenya. Biological control of invasive Opuntia species can be very successful when the correct agent is matched with the appropriate host.

SPEDE‐sampler: An R Shiny application to assess how methodological choices and taxon sampling can affect Generalized Mixed Yule Coalescent output and interpretation

Molecular Ecology Resources, Volume 22, Issue 5, Page 2054-2069, July 2022., 2022
Abstract Species delimitation tools are vital to taxonomy and the discovery of new species. These tools can make use of genetic data to estimate species boundaries, where one of the most widely used methods is the Generalized Mixed Yule Coalescent (GMYC) model.

We and herbivores eat endophytes

Microbial Biotechnology, Volume 14, Issue 4, Page 1282-1299, July 2021., 2021
Here a cycle of endophytic‐enteric‐soil‐endophytic microbes is proposed which has relevance for health and comprises the fate of animal faeces as natural microbial inoculants for plants that constitute bacterial sources for animal guts. Summary Health depends on the diet and a vegetal diet promotes health by providing fibres, vitamins and diverse ...

Equity in ecosystem restoration

Restoration Ecology, Volume 29, Issue 5, July 2021., 2021
The importance of equity has been emphasized in climate change, biodiversity loss, land degradation, and ecosystem restoration. However, equity implications are rarely considered explicitly in restoration projects. Although the role of equity has been studied in the context of biodiversity conservation and environmental governance, environmental ...

Five‐year field trial of the biomass productivity and water input response of cactus pear (Opuntia spp.) as a bioenergy feedstock for arid lands

GCB Bioenergy, Volume 13, Issue 4, Page 719-741, April 2021., 2021
Results of the first long‐term (5‐year) field trial of three different Opuntia species (O. ficus‐indica, O. cochenillifera, and O. streptacantha) for bioenergy production in the USA conducted in southern Nevada revealed an average annual biomass productivity of 11.6 Mg dry mass ha−1 at a relatively sparse planting density of 1418 plants ha−1 ...
