Microevolution of Pieris butterfly genes involved in host plant adaptation along a host plant community clineNARA Subscribed
Herbivorous insects have evolved counteradaptations to overcome the chemical defences of their host plants. Several of these counteradaptations have been elucidated at the molecular level, in particular for insects specialized on cruciferous host plants. While the importance of these counteradaptations for host plant colonization is well established, little is known about their microevolutionary dynamics in the field. In parti...
Molecular signatures of selection associated with host plant differences in Pieris butterfliesNARA Subscribed
Adaptive traits that enable organisms to conquer novel niches and experience subsequent diversification are ecologically and evolutionarily important. The larvae of Pieris butterflies express nitrile‐specifier proteins ( NSP s), a key innovation for overcoming the glucosinolate (GLS)‐myrosinase‐based defence system of their Brassicales host plants. Nitrile‐specifier proteins are a member of the NSP ‐like gene family, which inc...
The abundance of the northern form of the short‐finned pilot whale, Globicephala macrorhynchus , in the Pacific waters of northern Japan was estimated from a line transect survey conducted in 2006 and data from seven previous surveys collected between 1985 and 1997. To overcome the difficulty of small sample size and inconsistency in survey design, we used an adjustment method using multiple covariates and sensitivity analysis...
