Rainfall thresholds for triggering landslides are crucial to forecasting landslide occurrences. Various site-specific conditions, determination methodologies, and targeted scales (extent of the area in which the rainfall threshold is defined) can influence the rainfall thresholds. The predicting power of rainfall thresholds can be upgraded by clarifying and quantifying the effects of the controlling factors on them. Studies on...
Brain metabolite levels in remitted psychotic depression with consideration of effects of antipsychotic medicationNARA Subscribed
Background The neurobiology of psychotic depression is not well understood and can be confounded by antipsychotics. Magnetic resonance spectroscopy (MRS) is an ideal tool to measure brain metabolites non-invasively. We cross-sectionally assessed brain metabolites in patients with remitted psychotic depression and controls. We also longitudinally assessed the effects of olanzapine versus placebo on brain metabolites. Methods Fo...
NEOTROPICAL FRESHWATER FISHES : A dataset of occurrence and abundance of freshwater fishes in the NeotropicsNARA Subscribed
The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large‐scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distri...
Factors affecting water availability for high Arctic lichensNARA Subscribed
The daggertooth pike conger, M uraenesox cinereus ( F orsskål), has become an important fish resource in the western S eto I nland S ea, J apan, since the 1990s. However, introducing sustainable fisheries resource management for this species is difficult in this region because stock assessments have not been performed, and official fisheries statistics for this stock were discontinued after 2007. This study used existing limit...
Numerous empirical studies have reported lack of migration–drift equilibrium in wild populations. Determining the causes of nonequilibrium population structure is challenging because different evolutionary processes acting at a variety of spatiotemporal scales can produce similar patterns. Studies of contemporary populations in northern latitudes suggest that nonequilibrium population structure is probably caused by recent col...
Pacific Rim Forestry / Silviculture and Forest EcologyNARA Subscribed
Leucaena leucocephala (leucaena) is an important agroforestry tree of tropics and subtropics due to its protein rich foliages, ability to grow on poor soils, and high level of tolerance to various stresses including drought and diseases. We hypothesized that leucaena have a unique set of genes which confer tolerance to various abiotic and biotic stresses and these genes are either absent or not expressed in other legumes that...
Population genetic structure and effective population size of ayu ( Plecoglossus altivelis ), an amphidromous fishNARA Subscribed
The temporal and spatial population genetic structure of ayu Plecoglossus altivelis (Salmoniformes: Plecoglossidae), an amphidromous fish, was examined using analysis of variation at six microsatellite DNA loci. Intracohort genetic diversities, as measured by the number of alleles and heterozygosity, were similar among six cohorts (2001–2006) within a population (Nezugaseki River), with the mean number of alleles per cohort ra...
