Intertidal snail-trematode communities in southern Thailand were examined before and after the South Asia tsunami. Infection rates and species diversity of cercaria in the host snail Cerithidea in tidal zones did not change significantly from one year before to one month after the tsunami. However, the host snails C. quadrata, C. alata and C. obtusa disappeared from greatly damaged sites. It is...

snail is one of the worst causes of food allergy. thus, the aim of this study was to identify the major and minor allergens of the local marine snail ( cerithidea obtusa ) and subsequently to investigate the impacts of heat treatment on the ige-binding activity of snail allergens. proteins from raw and heat-treated snails (boiled, roasted and fried) were extracted and then resolved by sodium do...

Pollutants are persistent in the environment, taint food chain, and harm people's health because of their toxicity. In this study, mangrove snails called Cerithidea obtusa (C. Obtusa) were gathered from Southwest Johor, Malaysia, amounts macro micro elements Ca, Fe, K, Mg, Na, As, Mn, Zn soft tissues, shells, related surface sediments analysed. The Neutron Activation Analysis (NAA) method was u...

The main purpose of the research was to analyze distribution Arsenic (As), Cadmium (Cd), Copper (Cu), Iron (Fe), Nickel (Ni), Cobalt (Co), Mangan (Mn), and Zinc (Zn) in soft tissues, shells, associated surface sediments Cerithidea obtusa (C. obtusa) mangrove snails collected from Sungai Besar Sepang. concentration iron (Fe) found be highest relation other toxic elements sediments, shells C. obt...

The nonnative mudsnail Batillaria attramentaria was introduced to the west coast of North America in the early part of this century and has been displacing the native mudsnail Cerithidea californica on a marsh-by-marsh basis. We combined detailed, quantitative field data on this invader and its interactions with the native snail in an individualbased model that allowed us to address both genera...

Nitellopsis obtusa (starry stonewort) is a dioecious green alga native to Europe and Asia that has emerged as an aquatic invasive species in North America. Nitellopsis obtusa is rare across large portions of its native range, but has spread rapidly in northern-tier lakes in the United States, where it can interfere with recreation and may displace native species. Little is known about the invas...
