The reef biota in four Tasmanian marine reserves and at associated unprotected reference sites was investigated over a 6-year period following protection from fishing. The largest reserve at Maria Island (7 km coastline length) proved the most effective at achieving species conservation and resource enhancement. The number of fish, invertebrate and algal species, the densities of large fishes (...

In early summer 1995, we surveyed total system metabolism in the Plum Island estuary. Objectives included (1) estimation of ecosystem metabolism via open-water oxygen measurements, (2) determination of the autotrophic and heterotrophic regions of the estuary, and (3) comparison of the loading of organic carbon from the watershed to measurements of autochthonous production. Metabolism was calcul...

Although studies of population genetic structure are commonplace, a strong bias exists toward species from low latitudes and with relatively poor dispersal capabilities. Consequently, we used 280 amplified fragment length polymorphism bands to explore patterns of genetic differentiation among 8 populations of a high latitude broadcast-spawning marine mollusc, the Antarctic limpet Nacella concin...

background: agriculture is an important sector for the malaysian economy. the use of pesticides in agriculture is crucial due to its function in keeping the crops from harmful insects. children living near agricultural fields are at risk of pesticide poisoning. objective: to evaluate the genotoxic risk among children who exposed to pesticides and measure dna damage due to pesticides exposure. m...

purpose: scorpions in the middle eastern countries are known as the most widely spread poisonous creatures that cause casualties and death to human being and domestic animals. these creatures are distributed and well established in subtropical regions. among sixteen iranian islands in the persian gulf, kish island is the focus of important internal and foreign industrial and commercial activit...

The study investigated the stomach contents of Indian mackerel (Rastrelliger kanagurta) from the southern part of Qeshm Island in the Persian Gulf from April 2016 through March 2017. The food and feeding behavior of R. kanagurta with a fork length of 17.8 to 22.5 cm was assessed from the analysis of gut contents. The frequency of occurrence and numeric methods were used for stomach content anal...

parasitic infection of pampus argenteus was examined from northwest of qeshm island. a total of 62 specimens were caught in summer 2008 and winter 2009 by bottom trawl and the specimens were selected randomly in different length classes and immediately deep frozen. all samples were transferred to laboratory, after measuring fish weight and length, parasitological survey implemented by stereo an...

1 widespread island endemic, the San Clemente Island night lizard. ABSTRACT 17 Habitat fragmentation and loss are fundamental conservation concerns. Because protected 18 areas are often " habitat islands " isolated by human development, studies of physical islands 19 which document genetic patterns associated with natural versus anthropogenic fragmentation may 20 provide insight into the manage...
