this study reports the incidence of histological alterations in morphometric changes in the liver and ovary of acanthopagrus latus collected from an urban stream impaired by anthropogenic activities and from a clean site (reference). mercury concentration was determined using a standard cold vapor atomic absorption. the results showed that mercury concentration at the creek waters, and speciall...

Biological control of spotted knapweed (Centaurea stoebe) is an ongoing topic of research that holds ecological importance due to the extent to which knapweed has spread across the Western United States. Using herbivores (insects) as biological controls of spotted knapweed can be successful at reducing plant density in certain habitats. However, the exact relationship among the insects, knapwee...

The dark matter (DM) distributed around an intermediate massive black hole (IMBH) forms overdensity region called DM minispike. We consider the binary system which consists of IMBH with minispike and a small inspiralling in eccentric orbits. factors affect evolution orbit include gravity system, dynamical friction accretion caused by minispike, radiation reaction gravitational waves (GWs). Usin...

An ovigerous female of Argulus matuii Sikama, 1938 was collected from the body surface a yellowfin seabream Acanthopagrus latus (Houttuyn, 1782) in cove facing Bungo Channel off Ehime Prefecture, western Japan. This represents new host record for A. matuii, and is herein described. female, which fixed preserved 70% ethanol, showed prominent coloration, i.e., six streaks yellow fringed with dark...
