Predicting and managing plant invasions on offshore islands

Conservation Science and Practice, Volume 3, Issue 2, February 2021., 2021
Abstract Resources for biodiversity conservation are limited and it is therefore imperative that management actions that have the best chance of success are prioritized. Non‐native species (NNS) are one of the key problems facing biodiversity conservation, so understanding how NNS disperse and establish can inform more effective conservation planning ...

Nitrous Oxide Emissions from Smallholders’ Cropping Systems in Sub‐Saharan Africa

Advances in Agriculture, Volume 2021, Issue 1, 2021., 2021
Increased concentration of atmospheric nitrous oxide (N2O), a potent greenhouse gas (GHG), is of great concern due to its impact on ozone layer depletion leading to climate change. Ozone layer depletion allows penetration of ultraviolet radiations, which are hazardous to human health. Climate change culminates in reduced food productivity.

Pest categorisation of the non‐EU phytoplasmas of tuber‐forming Solanum spp.

EFSA Journal, Volume 18, Issue 12, December 2020., 2020
Abstract Following a request from the European Commission, the EFSA Panel on Plant Health performed a pest categorisation of four phytoplasmas of tuber‐forming Solanum spp. known to occur only outside the EU or having a limited presence in the EU. The only tuber‐forming species of Solanum reported to be phytoplasma infected is S. tuberosum.

Amphicarpic plants: definition, ecology, geographic distribution, systematics, life history, evolution and use in agriculture

Biological Reviews, Volume 95, Issue 5, Page 1442-1466, October 2020., 2020
ABSTRACT Although most plants produce all of their fruits (seeds) aboveground, amphicarpic species produce fruits (seeds) both above‐ and belowground. Our primary aims were to determine the number of reported amphicarpic species and their taxonomic, geographic, life form and phylogenetic distribution, to evaluate differences in the life history of ...

Embryology of Macroptilium arenarium (Leguminosae)

Australian Journal of Botany, 2006
Macroptilium arenarium (Bacigalupo) S.I.Drewes & R.A.Palacios produces two floral morphs, aerial chasmogamous flowers and cleistogamous flowers in geophyte racemes. A comparative study of the sporogenesis, gametogenesis and the development of the related sporophytic structures in both floral morphs is reported.

Forage seed production in the Sudano-sahelian zone of Cameroon

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 2000
