Despite increased focus on elucidating the various reproductive strategies employed by orchids, we still have only a rather limited understanding of deceptive pollination systems that are not bee- or wasp-mediated. In Europe, orchid Neotinea ustulata has been known to consist two phenologically divergent varieties, neither which provide rewards its pollinators. However, detailed studies their b...

Imidacloprid, a relatively long residual neonicotinoid soil insecticide, is often applied to lawns and golf courses in spring for preventive control of root-feeding white grubs. We evaluated effects of such applications on spring parasitism of the overwintered third-instar Japanese beetle, Popillia japonica Newman, by Tiphia vernalis Rohwer, an introduced solitary ectoparasitoid. Natural rates ...

This paper discusses the Target Strength (TS) results offish from in situ measurement at the life sea habitat compared to acoustic model. In situ measurement of fish Selarboops (Oxeye scad) and Megalaspiscordyla (Torpedo scad) have been deployed using Scientific Echo Sounder. Laterally and dorsally X-ray imaged of fish have been deployed to perform fish body and swim bladder morphology. Length,...

Species may become invasive after introduction to a new range because phenotypic traits pre-adapt them to spread and become dominant. In addition, adaptation to novel selection pressures in the introduced range may further increase their potential to become invasive. The diploid Leucanthemum vulgare and the tetraploid L. ircutianum are native to Eurasia and have been introduced to North America...

Boletus edulis, Boletus aestivalis, Boletus luridus, Amanita muscaria and Hebeloma radicosum mycelia were isolated in pure culture and characterised by morphological and molecular methods. Molecular identification was performed by sequence analyses from the ITS region of nuclear ribosomal RNA genes. The phylogenetic affiliation of the isolated mycelia were evaluated by comparison of their ITS s...
