Biodiversity is under threat by the ongoing global change and especially freshwater ecosystems are under threat by intensified land use, water abstraction and other anthropogenic stressors. In order to monitor the impacts that stressors have on freshwater biodiversity, it is important to know the current state of ecosystems and species living in them. This is often hampered by lacking knowledge...

Chemical examination of a Chinese soft coral Lobophytum pauciflorum resulted in the isolation of seven new biscembranoids named lobophytones U-Z(1) (1-7, resp.), together with methyl sartortuoate (8) and nyalolide (9). The structures of the new compounds were elucidated by 1D- and 2D-NMR (COSY, HSQC, HMBC, and NOESY) spectroscopic analysis in association with MS and IR data. All compounds were ...

The community’s reliance on logging forest resources has reached the limit of its carrying capacity. Non-timber products are one type natural resource that can help direct use timber products. Interviewing techniques and field observation were used to acquire data. findings show Arenga pinnata other non-timber (NTFPs) have economic potential as halal foods pinnata, Hevea brasiliensis, Durio zib...

1. The aim of this study was to estimate the amount of leaf litter ingested by the shredder caddis-fly Sericostoma vittatum in a small stream in central Portugal. The study combined field data on population dynamics and laboratory experiments to determine the effect of temperature (9, 12, 15 and 18 C), leaf species (Alnus glutinosa, Castanea sativa, Populus · canadensis and Quercus andegavensis...

Alder (Alnus glutinosa) and oak (Quercus robur) are dominant tree species in European Atlantic mixed forests, their leaf litter is a key resource for stream ecosystems. While alder has higher nutrient content palatability than other rapidly processed the by detritivores microorganisms, tougher less nutritious but more persistent resource. Given that both declining due to spread of fungal pathog...

This study was conducted to look at the types and spatial distribution of non-timber forest products (NTFPs). Data on NTFPs species, distribution, parts used obtained through species identification. Meanwhile, NTFP mapping activities use GIS. The results showed that there were 8 by villagers, namely Arenga pinnata, Hevea brasiliensis, Durio zibethinus, Areca catechu, Theobroma cacao, Parkia spe...
