Sakaerat Biosphere Reserve is one of the four Biosphere Reserves in Thailand. It is situated at Khorat Plateau and comprises of mainly dry evergreen forest and dry dipterocarp forest. Despite studies that document its rich biodiversity, there was no concerted study on the orthopteran diversity. Recent sampling by the authors in Sakaerat led to the discovery of numerous undescribed species. A checklist, first for the place, is also reported here, each species represented with a habitus photograph. In total, 128 species of Orthoptera from 11 families were recorded. Caelifera (grasshoppers) were represented with five families and Ensifera (crickets and katydids) were represented with six families, making up 10 of the 16 lineages in the orthoptera phylogeny.

Abstract Dry dipterocarp forests are among the most common habitat types in Thailand. Russulaceae are known as common ectomycorrhizal symbionts of Dipterocarpaceae trees in this type of habitat. The present study aims to identify collections of Russula subsection Amoeninae Buyck from dry dipterocarp forests in Thailand. A multi-locus phylogenetic analysis placed Thai Amoeninae collections in two novel lineages, and they are described here as Russula bellissima sp. nov. and R. luteonana sp. nov. The closest identified relatives of both species were sequestrate species suggesting that they may belong to drought-adapted lineages. The analysis of publicly available ITS sequences in R. subsect. Amoeninae did not confirm evidence of any of the new species occurring in other Asian regions, indicating that dry dipterocarp forests might harbor a novel community of ectomycorrhizal fungi. Macromorphological characters are variable and are not totally reliable for distinguishing the new species from other previously described Asian Amoeninae species. Both new species are defined by a combination of differentiated micromorphological characteristics in spore ornamentation, hymenial cystidia and hyphal terminations in the pileipellis. The new Amoeninae species may correspond to some Russula species collected for consumption in Thailand, and the detailed description of the new species can be used for better identification of edible species and food safety in the region.

This work aims to study soil physical and chemical properties in two forest types including dry dipterocarp forest (DDF) and mixed deciduous forest (MDF) located in Plant Genetic Protection Area under the Royal Initiative of Her Royal Highness Princess Maha Chakri Sirindhorn, Nampung dam EGAT, Sakon Nakhon province, Thailand. The samples were collected 3 times in December 2011, February and May 2012. The results showed that the average values of soil properties in MDF including, soil moisture, electical conductivity, organic matter, total nitrogen, avialable phosphorus and exchangeable potassium were higher than those in DDF. Only soil pH in MDF was less than that in DDF. It can be concluded that MDF have more fertility status of soil than DDF.

Faunistic records of spiders in dry dipterocarp forests of Thailand are presented. Spiders were surveyed from November 2008 to December 2012. A total of 1,926 spider individuals were collected from 16 locations by visually searching, sweeping grasses and herb vegetation, beating shrubs and trees, and shifting leaf litters. Spiders were identified to 106 species in 86 genera of 29 families. The families Araneidae, Salticidae, Thomisidae, Tetragnathidae, and Theridiidae exhibited higher species richness. Several families that are rare and poorly known in Thailand were recorded, such as Stenochilidae, Eresidae, Idiopidae, Theraphosidae, and Nemesiidae. A faunistic overview of the spiders found in dry dipterocarp forest is presented. In general, the diverse composition of spiders and their guilds and the occurrence of rare and poorly known species in the Thai region confirm the high biotic value of dry dipterocarp forests. Continuing to maintain dry dipterocarp forest functions should be considered in future studies.

ABSTRACTSmall mammal live-trapping was carried out in a dry tropical forest mosaic in Huai Kha Khaeng Wildlife Sanctuary, central Thailand. Trapping was done in two forest types in three seasons.Maxomys surijerwas the dominant species in both plots. The three most abundant species in each plot accounted for > 90% of all captures. Community structure, density, relative abundance, biomass, age structure of populations, and habitat usage of some small mammal species varied by forest type and season. The dry evergreen/mixed deciduous forest type supported a greater abundance and biomass of small mammals than the mixed deciduous/dry dipterocarp forest type in all seasons, although species richness was the same. The greatest density, biomass, and home-range size forMaxomys surijeroccurred in the rainy season in both forest types. Seasonal changes in ratios of adults and subadulls of several species suggested a breeding peak at the end of the dry season or beginning of the rainy season. The mixed deciduous/dry dipterocarp forest showed a drastic drop in numbers, density, and biomass of small mammals six weeks after a fire burned through it.

Dry dipterocarp forest is one of the ecosystems that features variety of rare plants and animals. The forest in Ia Pa district, Gia Lai province is declining owing to illegal logging and encroachment of forest land for cultivation. Forest degradation can reduce CO2 sequestration, contributing to increasing greenhouse gas emission and global warming. The study was carried out in the 4 quadrats (each 2,500 m2 = 50 × 50 m) in dry dipterocarp forest of Ia Pa district. In each quadrat, 5 sub-quadrats (each 25 m2 = 5 × 5 m) were set up, one at a central point and four at four corners of the quadrat, respectively. Based on the relationship between carbon stock and above-ground biomass, we found that CO2 accumulation in dry dipterocarp forest was 105.6 tons/ha corresponding to the economic value of 12,299,760 VND/ha. Thus, it is necessary to improve forest quality towards sustainable management of dry dipterocarp forest ecosystem and increase the economic value of the forest with respect to environmental services.
