BACKGROUND AND AIMS Phragmites australis is a wetland grass with high genetic variability, augmented by its cosmopolitan distribution, clonal growth form and large variation in chromosome numbers. Different ploidy levels and ecotypes differ in morphology and ecophysiological traits, and may possess different levels of phenotypic variation. The aim of this study was to quantify the natural varia...

Over a period of five years (2005–2010) a total of 358 red fox (Vulpes vulpes) serum samples were collected during regular hunting procedures, mostly in the continental part of Croatia. All samples were tested using the microscopic agglutination test (MAT) for the presence of specific antibodies (Ab) to 12 Leptospira spp. pathogenic serovars. Specific antibodies for 11 different Leptospira spp....

background & aim:  psyllium (plantago psyllium l.) is a native plant that grows widely in india and iran. different cases of using psyllium gum for its suitable rheological properties in a wide range of food products exist in nature. experimental: in this study, different fractions of psyllium gum were extracted by water and alkali treatments. rheological properties of these fractions were ...

We know very little about aging (senescence) in natural populations, and even less about plant aging. Demographic aging is identified by an increasing rate of mortality following reproductive maturity. In natural populations, quantifying aging is often confounded because changes in mortality may be influenced by both short- and long-term environmental fluctuations as well as age-dependent chang...

A diverse Diptera assemblage, dominated by the family Chloropidae, is associated with common reed (Phragmites australis (Cav.) Trin. ex Steudel, Poaceae) in the Palearctic region (Tewksbury et al. 2002). Although P. australis has long been present in North America, many of its associated Chloropidae have remained restricted to the Palearctic. The best-known chloropid associates of Phragmites ar...

PREMISE OF THE STUDY Intraspecific hybridization between native and introduced lineages of a species can increase invasiveness and may lead to the decline of native lineages. The introduction of Eurasian Phragmites australis has caused profound changes to wetland habitats across North America, yet evidence for hybridization between native and introduced Phragmites australis in North America is ...

Aquatic plants play an essential role and are effective in mitigating lake eutrophication by forming complex plant-soil system and retaining total nitrogen (TN) and phosphorus (TP) in soils to ultimately reduce their quantities in aquatic systems. Two main vegetation types (Phragmites australis community and P. australis + Typha latifolia community) of Qin Lake wetland were sampled in this stud...

Background: Marine seaweeds synthesize different types of compounds with various biological activities, including anti-tuberculosis and anticancer effects. Objective: The aim of this study was to evaluate anti tuberculosis of Padina australis and cytotoxicity of different fractions of this seaweed. Methods: Padina australis was collected from coasts of Persian Gulf, identified and e...
