The increasing human population and continuous demands of timber its derived products like composite wood, has created a significant pressure on the demand for high quality from forests. This, ultimately resulted in pressurising natural forests increase unvailibility production or durable one way to neutralize this is modify other non wood species having undesirable properties hygroscopicity, a...

Forest plantations with Toona ciliata are presented as economically viable thanks to the suitability of their wood for high-quality niche products. However, this study verifies whether investment projects in T. incorporation managerial flexibility. We apply technical-economic coefficients from forest over a 15-year planning horizon, considering project an underlying asset and price only source ...

Illegal logging and associated trade have increased worldwide. Such environmental crimes represent a major threat to forest ecosystems society, causing distortions in market prices, economic instability, ecological deterioration, poverty. To prevent illegal imports of products, there is need develop wood identification methods for identifying tree species regulated by the Convention on Internati...

Previous systematic arrangement on the ciliate order Urostylida was mainly based on morphological data and only about 20% taxa were analyzed using molecular phylogenetic analyses. In the present investigation, 22 newly sequenced species for which alpha-tubulin, SSU rRNA genes or ITS1-5.8S-ITS2 region were sampled, refer to all families within the order. Following conclusions could be drawn: (1)...

The transfer of selenium between bacteria and the ciliated protozoan, Paramecium putrinum, was examined in laboratory cultures. The population growth of the ciliate was not inhibited in the presence of the highest concentrations of dissolved selenite or selenate tested (10(3) micrograms liter-1). Experiments with radioactive 75selenite or 75selenate indicated that accumulation of selenium by ci...

Onboard incubation experiments were conducted to examine the feeding rates and selectivity of the cyclopoid copepod Oithona similis on natural assemblages of microplankton during the spring bloom in the Oyashio region. O. similis cleared ciliates at higher rates (2.8–11.9 mL copepod 1 d ) than dinoflagellates (1.4 mL copepod 1 d ), with no detectable ingestion of diatoms. Clearance increased wi...

Ciliate and yeast telomerase possess a nucleolytic activity capable of removing DNA from the 3' end of a single-stranded oligonucleotide substrate. The nuclease activity is thought to assist in enzyme proofreading and/or processivity. Herein, we report a previously uncharacterized human telomerase-associated nuclease activity that shares several properties with ciliate and yeast telomerases. Pa...
