many brook stickleback, Eucalia inconstans, from the English Coulee, a small stream in Grand Forks, were found infected with an unrecorded species of diplostomulum metacercaria; its life cycle has been reported in abstract (Hoffman, 1955). In 1953, 51 (82%) of the 62 sticklebacks examined were infected, but in 1955 a much smaller number was infected ; no exact records were kept in 1954 and 1955...

Pulmonary parasitism by pentastomids was examined in two lizard species inhabiting an area of restinga vegetation (coastal sand dunes) situated in the municipality of Mataraca (6 degrees 29' S and 34 degrees 56' W), on the extreme northern coast of Paraíba State, Brazil. A total of 123 lizards were collected, being 75 specimens of Micrablepharus maximiliani (Gymnophtalmidae) and 48 specimens of...

BACKGROUND In northern Vietnam the Neonatal health - Knowledge Into Practice (NeoKIP, Current Controlled Trials ISRCTN44599712) trial has evaluated facilitation as a knowledge translation intervention to improve neonatal survival. The results demonstrated that intervention sites, each having an assigned group including local stakeholders supported by a facilitator, lowered the neonatal mortalit...

The Chrysididae are a group of cleptoparasitic and parasitoid aculeate wasps with a large number of rare and endangered species. The taxonomy of this group has long been confusing due to the similarity of species and extensive intraspecific variation. We present for the first time a comprehensive dichotomous key for all 74 species found in the Nordic and Baltic countries. In addition to diagnos...

How geographically widespread biological communities assemble remains a major question in ecology. Do parallel population histories allow sustained interactions (such as host-parasite or plant-pollinator) among species, or do discordant histories necessarily interrupt them? Though few empirical data exist, these issues are central to our understanding of multispecies evolutionary dynamics. Here...

Two new species, namely Ancistrocerus transpunctatus You and Li, sp. n. and Ancistrocerus deqinensis You and Li, sp. n. are described and illustrated from Yunnan, China. A key to the Oriental species of the genus Ancistrocerus is provided.

In this study, commercial sea cucumber identification and some biological characteristics were investigated between Ayvalık and Çeşme. Ayvalık, Aliağa, Foça, Şakran and İzmir were selected as main stations. In the investigation where 70 stations were studied between 0 and 50 m depth 6 sea cucumber species were found. These were Holothuria tubulosa, Holothuria polii, Holothuria mammata, Holothur...

The oriental aphid Schizaphis piricola (Matsumura) is recorded for the first time in Europe, on the ornamental pear tree Pyrus calleryana in landscaped areas in Madrid (Spain). Data on the morphology of the forms on primary host (apterous and alate fundatrigeniae and fundatrices), and their biology and distribution are given. The keys for identifying species of Schizaphis (Schizaphis) in the Ib...
