Journal ArticleDOI
Impacts of invasive Iris pseudacorus L. (yellow flag) establishing in an abandoned urban pond on native semi-wetland vegetation
TL;DR: It is suggested that it is important to preferentially manage sites where the coverage of I. pseudacorus is above 50%, in order to preserve the local biodiversity, and it is essential that the cut reproductive organs are kept submerged under deep water for an effective control of the species.
Journal ArticleDOI
Effects of a herbicide on paddy predatory insects depend on their microhabitat use and an insecticide application.
Koya Hashimoto,Yuji Eguchi,Hiroki Oishi,Yuhei Tazunoki,Makoto Tokuda,Francisco Sánchez-Bayo,Koichi Goka,Daisuke Hayasaka +7 more
TL;DR: The abundance of phytophilous predators was more likely to decrease than that of benthic, nektonic, and neustonic predators when the herbicide was applied, and these indirect effects of the herbicides could not be detected when the insecticide was also applied.
Journal ArticleDOI
Seed germination characteristics of invasive Spartina alterniflora Loisel in Japan: implications for its effective management.
TL;DR: The environmental conditions suitable for germination of S. alterniflora, under variable conditions of cold stratification periods, temperature, light, light/dark, dark, and oxygen, were reported, and its seeds clearly preferred aerobic conditions to germinate.
Journal Article
Relationship between microenvironment of mangrove forests and epiphytic fern species richness along the Pan Yi River, Thailand.
TL;DR: In this paper, the authors presented a study on the effects of environmental pollution on the health of Thailand's environment and plant conservation, using the data collected from the National Parks, Wildlife and Plant Conservation (NPWC) of Thailand.
Journal ArticleDOI
Effects of two successive annual treatments of two systemic insecticides, imidacloprid and fipronil, on dragonfly nymph communities in experimental paddies
Daisuke Hayasaka,Kazutaka Suzuki,Tomoko Korenaga,Fuki Saito-Morooka,Takuji Nomura,Keita Fukasawa,Francisco Sánchez-Bayo,Koichi Goka +7 more
TL;DR: It is suggests that ecological impacts, and therefore risks, of imidacloprid and pronil on dragon y nymph communities depend more on soil residues than they do on waterborne residues.
