A greener and more scalable synthesis of biogenic polydisulfides from lipoic acid

ChemSusChem, Accepted Article.
Ring‐opening polymerization (ROP) of 1,2‐dithiolanes form polydisulfides, an emergent class of dynamic covalent polymers. However, both monomer and polymer syntheses typically require anaerobic and moisture‐free conditions, often employing hazardous reagents and solvents that limit scalability. Herein, we disclose efficient, scalable syntheses for poly(

OMIP‐114: A 36‐Color Spectral Flow Cytometry Panel for Detailed Analysis of T Cell Activation and Regulation in Small Human Blood Volumes

Cytometry Part A, EarlyView.
ABSTRACT This 36‐color flow cytometry panel is designed to characterize multiple lymphocyte compartments, with a focus on T cells, their memory subpopulations, and immune checkpoints in human whole blood samples. In clinical settings, the amount of blood available from patients for scientific research is often limited.

Discovery of Late Holocene‐aged Acropora palmata reefs in Dry Tortugas National Park, Florida, USA: The past as a key to the future?

The Depositional Record, EarlyView.
Emblematic of global coral‐reef ecosystem decline, the coral ecosystem‐engineer Acropora palmata is now rare throughout much of the western Atlantic. We report for the first time, a significant record of late‐Holocene A. palmata populations that existed from ~4500 to 375 years before present in the Dry Tortugas, FL, USA.

Shifting baselines of coral‐reef species composition from the Late Pleistocene to the present in the Florida Keys

The Depositional Record, EarlyView.
We produced the first reconstruction of the coral species composition of MIS5d–a reefs in the Florida Keys and compared it with existing regional records from MIS5e, the Holocene, the recent past (1996) and the present (2022) to evaluate how Florida's reefs changed throughout the late Quaternary.

Categorization Systems of Threatened Species [PDF]

Conservation Biology, 2007
de Grammont and Cuar´on (2006) provide interestinginformation about the way several countries of the West-ern Hemisphere address the issue of developing systemsfor threatened species categorization. Nevertheless, wedisagree with these authors on some fundamental pointsand think their conclusions that “the country categoriza-tions [they] evaluated have ...

Threatened species not necessarily rare, rare species not necessarily threatened

Environmental Conservation, 1997
In the beautifully-illustrated book of rare and threatened plants of Greece (Phitos et al. 1995), the selection of species is based strictly on the four World Conservation Union (IUCN) categories of ‘extinct’, ‘endangered’, ‘vulnerable’ and ‘rare’ (Lucas & Synge 1978). The Swedish ‘red data’ book of plants (Aronsson et al.

Conservation Genomics of Threatened Animal Species

Annual Review of Animal Biosciences, 2013
The genomics era has opened up exciting possibilities in the field of conservation biology by enabling genomic analyses of threatened species that previously were limited to model organisms. Next-generation sequencing (NGS) and the collection of genome-wide data allow for more robust studies of the demographic history of populations and adaptive ...

The threatened status of acipenseriform species: a summary

Environmental Biology of Fishes, 1997
...increased demand has recently driven the price of black market smoked sturgeon as high as $ 26 a kilogram. With poachers standing to gain roughly a third of this price [besides the much higher price of caviar], a large fish could be worth thousands of dollars.

The microbiome in threatened species conservation

Biological Conservation, 2019
Abstract As global biodiversity continues to reduce at an alarming rate, threatened species are increasingly being brought under intensive management or into captivity. However, current conservation management programmes are often impeded by poor animal health and low reproductive success. Microorganisms play vital roles in the growth and maintenance
