In vitro conservation and regeneration of Laelia anceps Lindl
South African Journal of Botany, 2019 Abstract Laelia anceps Lindl is an orchid endemic to Mexico that is endangered of extinction as a result of the fragmentation of its habitat and the overexploitation of its natural populations. Therefore, programs aimed at the conservation and propagation of this genetic resource should be implemented.

Prevalence of stimulant use and the role of opioid agonist treatment among people who inject drugs in France: Results from the COSINUS cohort study. [PDF]
Drug Alcohol RevAbstract Introduction The co‐use of stimulants and opioids, including opioid agonist treatment (OAT), is very prevalent worldwide. A large body of data exists on the association between stimulant use and its health complications, and on OAT effectiveness among people with opioid use disorder.

Virtual special issue: Social‐ecological systems research in tropical ecosystems
Biotropica, Volume 55, Issue 3, Page 563-567, May 2023., 2023 This paper assess the extent of research on social‐ecological systems in tropical ecosystems from 2010‐2022 and selects 12 articles for the virtual special issue on social‐ecological systems. Surprisingly, there were few articles on social‐ecological systems, but articles selected examined a diverse range of topics and regions. Abstract Biodiversity is

Smoothing out the misconceptions of the role of bark roughness in vascular epiphyte attachment
New Phytologist, Volume 238, Issue 3, Page 983-994, May 2023., 2023 Summary Vascular epiphytes represent c. 10% of all vascular plant species. In epiphytes, attachment is essential for survival throughout consecutive ontogenetic stages of their life, starting with: (1) initial propagule attachment to the host; followed by (2) the development of first root‐substrate connections; and (3) maintenance of this attachment ...

Genetic inference of orchid population dynamics on different‐aged lava flows in Costa Rica
Biotropica, Volume 55, Issue 1, Page 95-105, January 2023., 2023 Volcán Arenal lava flows represent natural, non‐anthropogenic habitat disturbance that permit precise knowledge of when these sites became available for colonization. By examining the levels and spatial distribution of genetic variation of five Epidendrum radicans populations growing on lava flows deposited in 1968 and 1992, we were able to infer ...

Applications in Plant Sciences, Volume 10, Issue 5, September-October 2022., 2022 Abstract Lewis Knudson first successfully germinated orchid seeds asymbiotically on artificial medium in 1922. While many orchid species have since been grown asymbiotically, the tremendous variation in how species respond to artificial medium and growth conditions ex situ has also become apparent in the past century.

The endodermal passage cell – just another brick in the wall?
New Phytologist, Volume 230, Issue 4, Page 1321-1328, May 2021., 2021 Summary The endodermis surrounds and protects the vasculature partly by depositing hydrophobic suberin in the cell walls. Yet, some cells remain unsuberised. These historically termed ‘passage cells’ are assumed to provide a low‐resistance pathway to the xylem. Only recently have we started to gain molecular insights into these cells, which allow us to

Molecular Ecology, Volume 30, Issue 8, Page 1791-1805, April 2021., 2021 Abstract Orchids differ from other plants in their extremely small and partly air‐filled seeds that can be transported long distances by wind. Seed dispersal in orchids is expected to contribute strongly to overall gene flow, and orchids generally express low levels of genetic differentiation between populations and low pollen to seed flow ratios ...
