Traditional knowledge promotes the protection of large old trees: A case from China's richest biocultural diversity area

People and Nature, EarlyView.
Abstract Large old trees are important ecological entities in human settlements, providing cultural values and ecological services that are threatened by current and future changes in global climate, land use and disturbance regimes. Some studies suggest incorporating social and cultural significance into the conservation of large old trees.

Antimycobacterial Activity ofTaxus baccata [PDF]

Pharmaceutical Biology, 2003
Crude extracts prepared from various parts of Taxus baccata L. have been evaluated for their antimycobacterial activity. A CHCl3 fraction of the heartwood and ethanol extract of the leaves exhibited a minimum inhibitory concentration value (MIC) against Mycobacterium tuberculosis H37Ra strain of 200 µg/ml.

Phylogeny and divergence times of the African and Malagasy Podocarpus (Podocarpaceae) and their taxonomic and biogeographic implications

TAXON, EarlyView.
Abstract Podocarpus is the most speciose genus of the podocarp family (Podocarpaceae) widely distributed in the mountain forests of subtropical and tropical Asia, the Neotropics and Australasia, where its members have been shown to have had multiple origins.

Transcriptome analyses provide insights into the expression pattern and sequence similarity of several taxol biosynthesis-related genes in three Taxus species

BMC Plant Biology, 2019
Background Taxol is an efficient anticancer drug; however, the accumulation of taxoids can vary hugely among Taxus species. The mechanism underlying differential accumulation of taxoids is largely unknown. Thus, comparative analysis of the transcriptomes

TAXUS III Trial: In-Stent Restenosis Treated With Stent-Based Delivery of Paclitaxel Incorporated in a Slow-Release Polymer Formulation [PDF]

, 2003
BACKGROUND: The first clinical study of paclitaxel-eluting stent for de novo lesions showed promising results. We performed the TAXUS III trial to evaluate the feasibility and safety of paclitaxel-eluting stent for the treatment of in-stent restenosis ...

Heading west: ecology of swift foxes in a novel landscape beyond their range

Wildlife Biology, EarlyView.
The swift fox Vulpes velox is generally associated with the short‐grass prairie ecosystem of the North American Great Plains; a system that has declined by approximately 50% over the last century. Yet, swift fox populations seem to demonstrate regional variation in trends, with some populations declining while others appear stable to increasing.

Cloning, Gene Expression Analysis, and Phylogenic Relationship of dbat Gene from Iranian Endemic Yew (Taxus baccata L.)

Journal of Medicinal Plants, 2013
Background: Taxol is one of the most important anticancer agents that its supply mainly depends on biological processes. 10 - deacetyl baccatin III- O- acetyl transferase (dbat) gene is one of the key genes in Taxol biosynthetic pathway and it is ...

Seasonal body mass dynamics mediate life‐history trade‐offs in a hibernating mammal

Journal of Animal Ecology, EarlyView.
We tested a suite of ecological hypotheses to explain variation in seasonal body mass dynamics of a fat‐storing mammalian hibernator. We further demonstrated that pre‐hibernation mass gain in ground squirrels mediates an annual allocation trade‐off between current and future reproduction as the squirrels forage and rear young under predation risk ...

Memory and mutualism in species sustainability: a time-fractional Lotka-Volterra model with harvesting

, 2020
We first present a predator-prey model for two species and then extend the model to three species where the two predator species engage in mutualistic predation. Constant effort harvesting and the impact of by-catch issue are also incorporated. Necessary
