The life history of the trematode Pygidiopsis macrostomum Travassos, 1928 is described for the first time. Rediae and cercariae were obtained from naturally infected snails Heleobia australis (d Orbigny), a new first intermediate host. Metacercariae were found encysted in the mesenteries of three naturally infected guppies, Phalloptychus januarius (Hensel), Jenynsia multidentata (Jenyns) (new h...

background: cornus sanguinea l subsp australis (c.a. mey.) jáv. (cornaceae) is a native species in north and northwest of iran. it is locally named siah-al. the genus cornus is rich source of anthocyanins. objective: in this study the antioxidant activity, total phenol and total anthocyanin contents of different extracts of c. sanguinea l subsp australis. were investigated for the first time. m...

Background: Constructed wetlands are systems designed based on the utilization of natural processes, including vegetation, soil, and their associated microbial assemblage to assist in treating different types of wastewater. Methods: Two local Appalachian plants (Louis latifolia and Phragmites australis) were planted into smallscale constructed wetlands to treat domestic wastewater in the North ...

In order to isolate and identify endophytic fungi of Phragmites australis, numerous samplings were conducted from the plants grown in the southern areas of the Caspian Sea in Guilan, Mazandaran and Golestan provinces and saline soils around the Lake Urmia at province of East Azarbaijan. Twenty-one isolates of the genus Radulidium were obtained from healthy tissues of P. au...

The RAB5 GTPase ARA6 of Arabidopsis thaliana is known to be involved in endosomal trafficking by targeting vesicles to the plasma membrane. During this process AtARA6 is working in close relationship with the SNARE protein VAMP727 (vesicle associated membrane protein 727). Recently, ARA6 of the characean green algae Chara australis (CaARA6) was shown to have properties similar to AtARA6, pointi...

An unexploited mixed species eel stock (Anguilla australis and A. dieffenbachii) in a Waikato pastoral stream, and its modification by fishing pressure.

Climate change is projected to increase stress for many coastal plant communities. Along large portions of the North American coast, habitat degradation from anthropogenic changes to the environment already threaten the community structure of tidal marshes and submerged aquatic grass beds. The potential loss of ecological services historically provided by these communities has been a long-stand...

Preliminary analysis is presented for J, H, and K 0 images of the Corona Australis cloud core. Color-color and color-magnitude diagrams reveal relatively few new cluster members. We conclude that the R Cr A infrared cluster consists of only about 30 members and its size reeects the available reservoir of molecular gas.
