The Leopard Cat Prionailurus bengalensis is thought to be Asia’s most abundant wild cat.  Yet, the species’ status is poorly known due to a lack of rigorous population estimates.  Based on the few studies available, Leopard Cats appear to be more abundant in degraded forests, potentially due to increased prey availability.  We conducted camera trap surveys, rodent live-trapping, and spatially-explicit capture-recapture analyses to estimate the density of Leopard Cats within a degraded tropical forest fragment (148km2) in northeastern Thailand.  A total effort of 12,615 camera trap nights across 65km2 of trapping area resulted in at least 25 uniquely identified individuals.  Average rodent biomass (the main prey of Leopard Cats) was highest in the dry evergreen forest (469.0g/ha), followed by dry dipterocarp forest (287.5g/ha) and reforested areas (174.2g/ha).  Accordingly, Leopard Cat densities were highest in the dry evergreen forest with 21.42 individuals/100km2, followed by the reforested areas with 7.9 individuals/100km2.  Only two detections came from the dry dipterocarp forest despite both an extensive survey effort (4,069 trap nights) and available prey.  Although the dipterocarp supported the second highest average rodent biomass, it lacked a key prey species, Maxomys surifer, possibly explaining low encounter rates in that habitat.  Our results provide important baseline information concerning the population status of Leopard Cat in southeastern Asia.  Further, our findings corroborate with other studies that found a tolerance among Leopard Cats for degraded forests, highlighting the potential for forest fragments to serve as long-term conservation areas for the species.

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.
