Living Collections of Threatened Plants in Botanic Gardens: When Is Ex Situ Cultivation Less Appropriate than Quasi In Situ Cultivation?

open access: yesJournal of Zoological and Botanical Gardens, 2023
Botanic gardens play an increasingly important role in the conservation of global biodiversity. However, although botanical gardens periodically report the results of introducing certain species of native flora, they rarely attempt to summarize existing ...

Living collections of botanic gardens as a means of ex situ conservation : a case study of African Violets (Saintpaulia) in Europe [PDF]

open access: yes, 2006
In all plant conservation, the priority is to maintain wild populations in situ (on site), which means that plants are conserved within their natural environment. Sometimes, as in the case of severely endangered Saintpaulia H. Wendl.

Elucidating the Role of Surface Ligands on the Oxidative Etching of Au Bipyramids During Photothermia Using Liquid Cell Transmission Electron Microscopy

open access: yesAdvanced Functional Materials, EarlyView.
Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...

A complete chloroplast genome of Sedum lushanense S. S. Lai 2004 (Crassulaceae: Crassuloideae)

open access: yesMitochondrial DNA. Part B. Resources
We determined the complete chloroplast genome sequence of Sedum lushanense S. S. Lai 2004. The genome was 148,691 bp in length, including a large single copy (LSC; 80,497 bp), a small single copy (SSC; 16,620 bp), and two inverted repeats (IR; 25,787 bp)

Conservation of the Lion: Preventing an Africa without the African Lion [PDF]

open access: yes, 2018
The African lion (Panthera leo) population is diminishing rapidly, approximately 43 percent since 1993. The species is currently listed as vulnerable by the International Union for Conservation of Nature (IUCN).

Genetic diversity and core subset selection in ex situ seed collections of the banana crop wild relative Musa balbisiana [PDF]

open access: yes, 2019
Crop wild relatives (CWRs) play a key role in crop breeding by providing beneficial trait characteristics for improvement of related crops. CWRs are more efficiently used in breeding if the plant material is genetically characterized, but the diversity ...

Translational Considerations for Injectable Biomaterials and Bioscaffolds to Repair and Regenerate Brain Tissue

open access: yesAdvanced Healthcare Materials, EarlyView.
The repair and regeneration of brain tissue faces both biological and technical challenges. Injectable bioscaffolds offer new opportunities to stimulate tissue regrowth in the brain by recruiting neural stem cells. Here, the translational issues are reviewed that need to be address to advance this promising new therapeutic approach from the bench to ...

Macroecological Analysis of Bird Migration Routes in North America Using eBird Data: Beta Diversity Perspective

open access: yesDiversity
Bird migration routes across North America, which are often speculated upon at the microscale, are now subject to scrutiny using the ‘eBird’ database, the world’s largest data repository for the North American continent.

The complete mitochondrial genome sequence of Liobagrus mediadiposalis (Teleostei, Siluriformes, Amblycipitidae)

open access: yesMitochondrial DNA. Part B. Resources, 2017
The south torrent catfish Liobagrus mediadiposalis (Teleostei, Siluriformes, Amblycipitidae) is an endemic species of Korea. The complete mitochondrial genome sequence consisted of 16,534 base pairs (bp) encoding 13 protein-coding genes (PCGs), two ...

Bifunctional Surfaces With Immobilized Antibodies and Bioactive Peptides Mediate Selective Capture and Proliferation of Endothelial Colony‐Forming Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
A tunable bifunctional surface is developed by combining Fc‐binding peptides and RGD motifs to present oriented antibodies alongside integrin‐mediated signaling. The platform selectively captures endothelial colony‐forming cells while promoting their adhesion and proliferation.
