The first comprehensive revision of all the species attributed to Melomys led J. I. Menzies in 1996 to resurrect the genus Paramelomys and to redefine its morphologicallimits and species content. Menzies created P. gressitti as a new species belonging to a group displaying morphological similarities and including also P. lorentzii and P. moncktoni. Monotypic Distribution. E New Guinea. Descriptive notes. Head-body 135-162 mm, hindfoot 30-34 mm; no specific data are available for body weight. Gressitt's Mosaic-tailed Rat is a medium-sized Paramelomys with a soft, thick and woolly pelage, a long narrow foot, and a tail with three hairs per scale. It exhibits a medium-sepia dorsal pelage and a gray-buff ventral one. Tail is slightly shorter (99%) than head-body length. The skull has a narrow zygomatic plate. Habitat. Moist tropical mountain forest between 2300 m and 2400 m. Food and Feeding. No information. Breeding. No information. Activity patterns. Gressitt's Mosaic-tailed Rat is terrestrial. Movements, Home range and Social organization. No information. Status and Conservation. Classified as Endangered on The IUCN Red List owing to its small geographic range (less than 3500 km?*) and the destruction ofits habitat by mining and logging activities. The major threat to Gressitt's Mosaic-tailed Rat is ongoing habitat degradation caused by nearby human populations; habitat on Mount Kandy has been destroyed by gold-miners and wood-cutters. Bibliography. Menzies (1996). in Muridae

Soil respiration in a successional tropical forest in Thailand
<p class="p1">Soil respiration (SR) in forests contributes significant emissions of carbon from terrestrial ecosystems into the atmosphere. Soil respiration is highly sensitive to environmental changes because it is affected by many factors, including soil temperature, soil moisture, microbial community, surface litter and vegetation type. Indeed, a small change in SR may have large impacts on the global carbon balance, further influencing feedbacks to climate change. Thus, detailed characterization of SR responses to changes in environmental conditions is needed to accurately estimate carbon dioxide emissions from forest ecosystems. However, data for such analyses are still limited, especially in tropical forests of Southeast Asia where various stages of forest succession exist due to previous land-use changes. In this preliminary study, we measured SR and some environmental factors including soil temperature (ST), soil moisture (SM) and organic matter content (OM) in three successional tropical forests in both wet and dry seasons. We also analyzed the relationships between SR and the three environmental variables. Results showed that SR was higher in the wet season and in older forests. While no response of SR to ST was found in younger forest stages, SR of the old-growth forest significantly responded to ST, plausibly due to the non-uniform forest structure, including gaps, that resulted in a wide range of ST. Across forest stages, SM was the limiting factor for SR in the wet season whereas SR significantly varied with OM in the dry season. Overall, our results indicated that the responses of SR to environmental factors were mediated by seasons and forest succession. These findings call for further investigations on SR and its variations with environmental factors in tropical forests with detailed temporal and spatial scales, particularly in Southeast Asia where patches of successional stages dominate.</p>

Effects of El Niño drought on seedling dynamics in a seasonally dry tropical forest in northern Thailand
<p><span>As El Niño is predicted to become stronger and more frequent in the future, it is crucial to understand how El Niño-induced droughts will affect tropical forests. Although many studies have focused on tropical rainforests, there is a paucity of studies on them, particularly in Asia, and few studies have focused on seedling dynamics, which are expected to be strongly affected by drought. Seedlings in seasonally dry tropical forests (SDTFs) are generally more drought-tolerant than those in the rainforests, and the effects of El Niño-induced droughts may differ between SDTF and tropical rainforests. In this study, we explored the impact of El Niño-induced drought at an SDTF in northern Thailand by monitoring the seedling dynamics at monthly intervals for seven years, including a period of strong El Niño. The effects were compared between two forest types in an SDTF: a </span><span>deciduous dipterocarp forest (DDF)</span><span>, dominated by deciduous species, and an adjacent </span><span>lower montane forest</span><span> (LMF) with more evergreen species. El Niño-induced drought increased seedling mortality in both forest types. The effect of drought was stronger in evergreen than in the deciduous species, resulting in higher mortality in the LMF during El Niño. However, El Niño increased seedling recruitment only in the DDF, mainly because of the massive recruitment of the deciduous oak, <em>Quercus brandisiana</em> (Fagaceae), which compensated for the mortality of seedlings in the DDF. As a result, El Niño increased seedling density in the DDF and decreased it in the LMF. This is the first long-term study to identify the differences in the impacts of El Niño on seedlings between the two forest types, DDF and LMF, and two leaf habits, evergreen and deciduous, in Southeast Asia. Our findings suggest that future climate change may alter the species composition and spatial distribution of seedlings in Asian SDTFs.</span></p>
