Behavioral syndromes—suites of correlated behaviors across different situations and contexts—are widespread and can have important ecological consequences because correlations between distinct behaviors shape how animals respond to changing environmental conditions and can limit behavioral plasticity. Behaviors such as vigilance, foraging, and exploration are correlated in many species and thus constitute a syndrome. Studying...
The Nature of Oceanic Dispersal in the Diversification Process on Insular Systems in AsiaNARA Subscribed
Aim To clarify the characteristics and contribution of oceanic dispersal (OD), a representative of long‐distance dispersal, to phylogenetic diversification on insular systems. Location Eastern Eurasia. Time Period Post‐Neogene. Major Taxa Studied Freshwater snails of the genus Gyraulus (Mollusca: Gastropoda). Methods We conducted comprehensive sampling across the entire distribution range of G. chinensis group, including sever...
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...
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...
