Data from: Nuclear internal transcribed spacer-1 as a sensitive genetic marker for environmental DNA studies in common carp Cyprinus carpio

Toshifumi Minamoto, Kimiko Uchii, Teruhiko Takahara, Takumi Kitayoshi, Tsuji Satsuki, Hiroki Yamanaka, Hideyuki Doi & Satsuki Tsuji
The recently developed environmental DNA (eDNA) analysis has been used to estimate the distribution of aquatic vertebrates by using mitochondrial DNA (mtDNA) as a genetic marker. However, mtDNA markers have certain drawbacks such as variable copy number and maternal inheritance. In this study, we investigated the potential of using nuclear DNA (ncDNA) as a more reliable genetic marker for eDNA analysis by using common carp (Cyprinus carpio). We measured the copy numbers of cytochrome b...

Data from: The price of being seen to be just: an intention signalling strategy for indirect reciprocity

Hiroki Tanaka, Hisashi Ohtsuki & Yohsuke Ohtsubo
Cooperation among strangers is a marked characteristic of human sociality. One prominent evolutionary explanation for this form of human cooperation is indirect reciprocity, whereby each individual selectively helps people with a ‘good’ reputation, but not those with a ‘bad’ reputation. Some evolutionary analyses have underscored the importance of second-order reputation information (the reputation of a current partner's previous partner) for indirect reciprocity as it allows players to discriminate justified ‘good’ defectors, who selectively deny giving...

Data from: Functional significance of petals as landing sites in fungus-gnat pollinated flowers of Mitella pauciflora (Saxifragaceae)

Koki R. Katsuhara, Shumpei Kitamura & Atushi Ushimaru
Despite the well-known visual attraction function of angiosperm petals, additional roles of these floral organs (e.g. the provision of landing-site platforms for pollinators) have rarely been examined. This is likely because most petals perform multiple functions, making it difficult to isolate the importance of landing sites in pollination success. We investigated the landing-site function of dull-coloured pinnately branched petals in Mitella pauciflora flowers, which are predominantly pollinated by fungus gnats. We conducted a field experiment,...

Data from: Hidden diversity and phylogeographic history provide conservation insights for the edible seaweed Sargassum fusiforme in the Northwest Pacific

Zi-Min Hu, Jing-Jing Li, Zhong-Min Sun, Xu Gao, Jian-Ting Yao, Han-Gil Choi, Hikaru Endo & De-Lin Duan
Understanding the evolutionary processes that have created diversity and the genetic potential of species to adapt to environmental change is an important premise for biodiversity conservation. Herein, we used mitochondrial trnW-L and cox3 and plastid rbcL-S data sets to analyze population genetic variation and phylogeographic history of the brown alga Sargassum fusiforme, whose natural resource has been largely exterminated in the Asia-Northwest Pacific in the past decades. Phylogenetic trees and network analysis consistently revealed three...

Data from: Low functional diversity promotes niche changes in natural island pollinator communities

Masayoshi K. Hiraiwa & Atushi Ushimaru
Functional diversity loss among pollinators has rapidly progressed across the globe and is expected to influence plant–pollinator interactions in natural communities. Although recent findings suggest that the disappearance of a certain pollinator functional group may cause niche expansions and/or shifts in other groups, no study has examined this prediction in natural communities with high plant and pollinator diversities. By comparing coastal pollination networks on continental and oceanic islands, we examined how community-level flower visit patterns...
