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.

Common Reed (Phragmites australis) is a frequent component of inland and coastal wetlands in temperate zones worldwide. Ongoing environmental changes have resulted in the decline of this species in many areas and invasive expansion in others. In the Gippsland Lakes coastal waterway system in south-eastern Australia, increasing salinity is thought to have contributed to the loss of fringing P. a...

In Australia the frog family Microhylidae is largely restricted to tropical rainforests of the Wet Tropics region in the northeast of the country, but in that region the family is diverse. Only one species, Cophixalus ornatus, is widespread in the Wet Tropics but there has been suspicion that it may comprise multiple species. A recent study (Hoskin et al. 2011) assessed genetic and phenotypic v...

Leishmaniasis and Chagas disease afflict the poorest countries in the world. The Brazilian flora represents a rich source for the screening of potential antiparasitic compounds. In this work, we tested the total alkaloid and ethanol extracts of nine different plants from Brazilian families which produce isoquinoline alkaloids, to determine their in vitro antiparasitic effect against L. chagasi ...

Roads, bridges, and dikes constructed across salt marshes can restrict tidal flow, degrade habitat quality for nekton, and facilitate invasion by non-native plants including Phragmites australis. Introduced P. australis contributes to marsh accretion and eliminates marsh surface pools thereby adversely affecting fish by reducing access to intertidal habitats essential for feeding, reproduction,...

In southern Taiwan, rivers sporadically cease to flow and dry up in winter. The exposed riverbeds are very vulnerable wind erosion. strong northeast monsoon often induces serious estuarine sand drift fugitive dust, which cause damages agricultural crops, human health infrastructures. Giant reed (Arundo formosana), common (Phragmite australis) the wild sugarcane (Saccharum spontaneum) pioneer gr...

Scutopalus tomentosus sp. nov. is described and illustrated from Plantago tomentosa Lam. (Plantaginaceae) in a vineyard agroecosystem at Dois Lajeados county, State of Rio Grande do Sul, Brazil. This is the first species of this genus described from the Americas. A key to world species is included.

In rats, the effects of a 4-week supplementation of a fibre-free elemental diet with 100 or 200 g Plantago ovata seeds/kg was compared with that of the husks and wheat bran. The seeds increased faecal fresh weight up to 100%, faecal dry weight up to 50% and faecal water content up to 50%. The husks, at the high concentration only, were more effective and wheat bran less effective. Length and we...

Habenaria mosaic virus (HaMV), a member of the genus Potyvirus in the family Potyviridae, was first discovered from Habenaria radiata in Japan. The complete genomic sequence of a South Korean isolate (PA1) of HaMV infecting Plantago asiatica L. was determined with high-throughput RNA sequencing.
