Biological control of weeds in Australia: the last 120 years

open access: yesAustral Entomology, Volume 62, Issue 2, Page 133-148, May 2023., 2023
Abstract The development of the field of biological control of weeds in Australia is described, from the first attempts in 1903 to the present day. The interest sparked by the obvious success of prickly pear program, apparent from 1930 to 1935, resulted in several programs during the next 20 years, followed by a decline in activity until the 1970s when

Wild herbivores enhance resistance to invasion by exotic cacti in an African savanna

open access: yesJournal of Ecology, Volume 111, Issue 1, Page 33-44, January 2023., 2023
Our experimental and observational findings that wild herbivores confer resistance to invasion by exotic cacti add to evidence that conserving and restoring native herbivore assemblages (particularly megaherbivores) can increase community resistance to plant invasions. Photo credit: Gustavo Lozada (same for potential cover image). Abstract Whether wild

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

open access: yesWeed 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.

We and herbivores eat endophytes

open access: yesMicrobial 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

open access: yesRestoration 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

open access: yesGCB 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 ...

Insecticidal potential of Streptomyces sp. dichloromethane extracts against the cactus cochineal Dactylopius opuntiae (Cockerell)

open access: yesNotulae Scientia Biologicae, 2023
Destructive damages caused by Dactylopius opuntiae (Cockerell) to cactus worldwide require an ecofriendly IPM approach. Streptomyces sp. produce wide range of biologically active secondary metabolites that can be an interesting alternative to chemical ...

Additional file 1 of Functional genomics of a Spiroplasma associated with the carmine cochineals Dactylopius coccus and Dactylopius opuntiae

open access: yes, 2021
Additional file 1: Figure S1. Maximum-likelihood phylogenetic tree of the 16S rRNA from different Mollicutes. In red are the 16S rRNA sequences of S. ixodetis DO, DCM and DCF. Scale bar indicates 2% estimated sequence divergence. ModelFinder was used to calculate the TVMe+R4 nucleotide substitution model.
