Monogenea is one of the most species-rich groups of parasitic flatworms. Research on this taxon in Africa has been recently intensified. For example, already more than 100 nominal species belong to Cichlidogyrus, a genus mostly occurring on cichlids. Twenty-two of these were described from Lake Tanganyika which is a biodiversity hotspot in which many vertebrate and invertebrate taxa underwent u...

Livestock plays an essential role in supporting mixed production systems, particularly traction, fertilization, and adaptation to climatic problems. However, the breeding of small ruminants on pasture limited by numerous parasites. Thus, knowledge parasitic fauna is for a better approach parasite control. In this sense, study consisted determining prevalence gastrointestinal parasites evaluate ...
Small concretions and specimens embedded in the matrix have yielded a new Pliocene crustacean fauna from the Kowai Formation near Makikihi, South Canterbury, New Zealand. The fauna is relatively robust, with five identifiable taxa. Three new species are named herein, including the isopod Cirolana makikihi and the decapods Upogebia kowai and Austrohelice manneringi. one new genus and species of ...
Collections of23 macroinvertebrate taxa associated with Durvillaea antarctica hold fasts and 58 invertebrate taxa associated with artificial substrata coliectots are described flOm shallow-water and intertidd habitats at Heard Island. The fauna strong biogeographic affinities with the Kerguelen Island fauna and, to a slightly lesser extent, the fauna recorded at Macquarie Island but negligible ...
Longstanding observations suggest that dissolved materials are lost from fresh litter through leaching, but the role of soil fauna in controlling this process has been poorly documented. In this study, a litterbag experiment employing litterbags with different mesh sizes (3 mm to permit soil fauna access and 0.04 mm to exclude fauna access) was conducted in three habitats (arid valley, ecotone ...
The Australasian and southwest Pacific species of Oxyscelio (Hymenoptera: Platygastridae s.l.) are revised. A total of 80 species are recognized as valid, 13 of which are redescribed: O. atricoxa (Dodd), O. concoloripes (Dodd), O. flavipes (Kieffer), O. grandis (Dodd), O. hyalinipennis (Dodd), O. magniclava (Dodd), O. mirellus (Dodd), O. montanus (Dodd), O. nigriclava (Dodd), O. nigricoxa (Dodd...
background: in anzali lagoon, there are some endemic and exotic fishes. the present study was conducted to compare the parasitic fauna of blicca bjeorkna , as an endemic fish and hemiculter leucisculus , as an introduced fish to the lagoon. methods: a parasitological investigation was done on 78 specimens of b. bjoerkna and 114 of h. leucisculus . the fishes were collected from august 2009 to...
Fauna Europaea is Europe's main zoological taxonomic index, making the scientific names and distributions of all living, currently known, multicellular, European land and freshwater animals species integrally available in one authoritative database. Fauna Europaea covers about 260,000 taxon names, including 145,000 accepted (sub)species, assembled by a large network of (>400) leading specialist...
