Anecdotes or Ecological Patterns: Symbiotic Foraging Behaviors in Coyotes and Badgers 奇特模式还是生态格局: 郊狼与獾的共生觅食行为

Wildlife Letters, EarlyView.
Using a 3‐year, broad‐scale camera‐trap network in western Kansas, we tested whether coyotes and American badgers exhibit spatiotemporal patterns consistent with coordinated hunting. Despite high diel activity overlap, detection‐conditioned co‐detections occurred far less frequently than expected under independence, and short‐term temporal sequencing ...

Compound Taxus exerts marked anti-tumor activity and radiosensitization effect on hepatocellular carcinoma cells

Heliyon
Background: Compound Taxus capsule, as an antineoplastic Chinese patent drug, has been increasingly applied as an adjunctive treatment for the management of non-small-cell lung cancer (NSCLC) and some other malignancies, but research about its antitumor ...

Baseline survey of root-associated microbes of Taxus chinensis (Pilger) Rehd. [PDF]

PLoS ONE, 2015
Taxol (paclitaxel) a diterpenoid is one of the most effective anticancer drugs identified. Biosynthesis of taxol was considered restricted to the Taxus genera until Stierle et al.

Can Wapiti (Cervus elaphus) Browsing Stimulate the Chemical Defense of Taxus cuspidata—A Case of Northeast China Tiger and Leopard National Park

Integrative Zoology, EarlyView.
We study that browsing by wapiti reduces the growth of saplings, and it develop chemical defenses to prevent themselves browsed again. These results reduce our concern about wapiti browse T. cuspidate saplings, and provide basic data for the study of the interaction between them, and also provide theoretical basis for the population restoration and ...

Developing High-Efficiency PCR Mini-Barcoding to Enforce Conservation Efforts Against Illegal Trade and Habitat Loss of Endangered Taxus L. in the Himalayas

Conservation
Environmental and ancient DNA are mostly present in degraded forms in nature. Plant forensics is necessary for plants like Taxus (Taxaceae), which is a medicinal, as well as poisonous, endangered plant.

Characterization of Yew Tree () Varieties by Fingerprint and Principal Component Analyses

Natural Product Communications, 2012
The composition of varieties of Taxus growing in Estonia was analyzed by capillary electrophoresis with diode array detection (CE-DAD) for the separation of phenolic compounds, and by high performance liquid chromatography-mass spectrometry (HPLC-MS) for

Ultrasonic Extraction and Separation of Taxanes from Taxus cuspidata Optimized by Response Surface Methodology

Separations, 2022
Taxanes are natural compounds with strong antitumor activity. In this study, we first extracted taxanes from the needles of Taxus cuspidata using ultrasonic (US) extraction, and then assessed the effects of different extraction conditions on the yields ...

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Integrative multi-omics reveals shading effects on polysaccharide and secondary metabolism in Taxus media × T. yunnanensis

Environmental and Experimental Botany
Light is a critical environmental factor that regulates plant development and secondary metabolism, but its molecular influence on paclitaxel biosynthesis in Taxus remains unclear.

Metabolic Variations of Flavonoids in Leaves of T. media and T. mairei Obtained by UPLC-ESI-MS/MS

Molecules, 2019
The needles of Taxus species contain a large number of bioactive compounds, such as flavonoids. In the present study, the total flavonoid content in leaves of Taxus media and Taxus mairei was 19.953 and 14.464 mg/g, respectively. A total of 197 flavonoid
