Marine Mollusks

: Marine mollusks are a prolific source of secondary metabolites with complex/diverse structures and various aspects of biological activities. For above mentioned reason, these animals have been being extensively explored and became the hotspot of research subject in the recent years. It is well documented that mollusks can escape from predation by utilizing bioactive metabolites as defensive chemicals. In the last decade, the possible diet relationship between the South China Sea mollusks and their related potential prey organisms, including sponges, corals, algae, etc. have been systematically investigated. A series of interesting results have been obtained concerning the chemistry, chemoecology and pharmacological profiles of the studied marine organisms. The present review focuses on recent development dealing with chemistry, chemoecology, and bioactivity of the South China Sea mollusks and their dietary organisms.

AbstractTicks were collected from 2136 small mammals, comprising 5 bats (5 species), 14 elephant shrews (3 species), 84 Crocidura shrews (5 species), 25 hares (1 species), 10 small carnivores (3 species), 3 hyraxes (1 species) 1998 rodents (33 species), and from 41 birds (19 species) at various localities in Zambia. From these hosts 6568 ticks (4384 larvae, 1686 nymphs, 317 males and 181 females) were recovered. Twenty-three species were positively identified and nineteen other species were assigned to genus or species-group. Host and tick records are tabulated by regions collected and for each of the two regions with the largest collections, the records are tabulated by months. The ticks collected in the high montane area near the Malawi border differed significantly from collections in other areas studied, reflecting host and climate differences. In the two areas tabulated by month, most of the immature ticks were recovered in the cool dry winter months (April to August).

Identification Of Species

Morphological descriptions of the first larval stages of Persephona mediterranea, P. lichtensteinii and P. punctata (Leu-cosiidae: Eballinae) from the South Atlantic are provided, with comparisons among the morphometry of the species. Adetailed description and eight morphometric measurements were made for each larva, and a discriminant function analysiswas used to interpret the data set. The species differed significantly in certain morphological and morphometric features.These characteristics may help in the identification of species of Leucosioidea found in the South Atlantic, and can be an important tool in ecological studies, supporting the identification of planktonic morphotypes at the species level.
