Boreal peatlands occupy about 1.14 x 106 km2 in North America. Fires can spread into peatlands, burning the biomass, and if moisture conditions permit, burning into the surface peat. Charred layers in peat sections reveal that historically bogs in the subhumid continental regions and permafrost peatlands of the subarctic regions have been the most susceptible to fires. Fire return periods were ...

The influence of habitat structure and support availability on support use is an important aspect of understanding locomotor behavior in arboreal primates. We compared habitat structure and support availability in three orangutan study sites-two on Sumatra (Pongo abelii) in the dry-lowland forest of Ketambe and peat swamp forest of Suaq Balimbing, and one on Borneo (Pongo pygmaeus wurmbii) in t...

1. The coastal peat swamp forests of Sarawak, Malaysian Borneo, are undergoing rapid conversion, predominantly into oil palm plantations. This wetland ecosystem is assumed to have experienced insignificant disturbance in the past, persisting under a single ecologically-stable regime. However, there is limited knowledge of the past disturbance regime, long-term functioning and fundamentally the ...

Abstract The Indonesian government plans to turn Central Kalimantan into a national food barn by planting rice in several places, including shallow peatlands. Tropical peatlands actually have limited potential for agricultural use because the growing medium some cases is not conducive root development, waterlogged soils that poison plants. physical, chemical, and biological properties of water ...

The Alborz coal basin is located in northern part of Iran. The coal deposits of Shahrood in eastern Alborz, Zirab in central Alborz and Abyek in western Alborz were studied as typical coalfields of the basin. Shemshak Formation which is the main coal-bearing sequence was formed during the Triassic-Jurassic in the basin. It consists of sandstone, siltstone, shale and claystone, which variedly al...

Tree stumps of arborescent lycopods were discovered in situ at the contact of the Herrin (No. 6) Coal and the Energy Shale Members, near the Walshville paleochannel, the major river channel running through and draining the Herrin coal swamp. The stumps are associated with, and in one case attached to, fallen trunks identified as a Lepidodendron similar to L. aculeatum. The stumps and trunks occ...

The four fish species, Trichogaster pectoralis, Barbodes schwanenfeldii, Osphronemus gouramy, and Wallago leeri have the same body size, representing different habitats. Therefore, this study aimed to determine species swimming abilities speeds, including sustained, maximum prolonged speed, burst speed. were brought using oxygenated plastic bags Aquatic Resources Utilization Laboratory at Riau ...
