Information about the role of birds in dissemination of wild berry plants in the south of the Russian Far East taiga zone is presented based on the authors’ long-term ecological investigations and reviewed references are given. The dominant and subdominant species of carpophagous birds are determined. The participation of birds in dissemination of seeds of wild berry plants during the periods of nomad and seasonal migrations is discussed.
Newcastle disease (ND) is a serious neurological and respiratory disease of poultry that affects all types of birds but has traditionally not caused symptoms in wild aquatic birds, the natural hosts. In the late 1990s, a new genotype, viz. 5d that is pathogenic to all types of birds, including wa...
Sweet potato mild mottle virus (SPMMV) is the type member of the genus Ipomovirus (family Potyviridae). SPMMV occurs in cultivated sweetpotatoes (Ipomoea batatas Lam.; Convolvulaceae) in East Africa, but its natural wild hosts are unknown. In this study, SPMMV was detected in 283 (9.8 %) of the 2...
The natural habitat of wild P. ginseng is currently found only in the Russian Primorye and the populations are extremely exhausted and require restoration. Analysis of the genetic diversity and population structure of an endangered species is a prerequisite for conservation. The present study aim...
The rural populations in Ethiopia have a rich knowledge of wild edible plants and consumption of wild edible plants is still an integral part of the different cultures in the country. In the southern part of the country, wild edible plants are used as dietary supplements and a means of survival d...
The intraspecific chemical variability of essential oils (50 samples) isolated from the aerial parts of Artemisia herba-albaAsso growing wild in the arid zone of Southeastern Tunisia was investigated. Analysis by GC (RI) and GC/MS allowed the identification of 54 essential oil components. The mai...
To provide a systematical revision of the traditional use of wild and cultivated plants in north-eastern Bosnia and Herzegovina (Western Balkan Peninsula; Southeast Europe). Thereby, it will extend and complement a recent previous study carried out in middle, southern and western Bosnia and Herze...
Here we describe the modification and use of a new tool type in the woodpecker finch (Cactospiza pallida). This species is known to habitually use twigs or cactus spines to extract arthropods out of tree holes. We observed an adult and a juvenile bird using several barbed twigs from introduced bl...
Since 1997, when human infections with a highly pathogenic (HP) avian influenza A virus (AIV) subtype H5N1 - previously infecting only birds - were identified in a Hong Kong outbreak, global attention has focused on the potential for this virus to cause the next pandemic. From December 2003, an u...
Basal metabolic rate (BMR) of birds is beginning to be viewed as a highly flexible physiological trait influenced by environmental fluctuations, and in particular changes in ambient temperatures (Ta). Southern Africa is characterized by an unpredictable environment with daily and seasonal variati...
To study the reliability between in vitro and in vivo data collected downstream 2 sewage treatment plants (STP) as well as from bleached kraft mill industry (BKME), 5 rivers (3 impacted and 2 references) were investigated in the Walloon region (southern of Belgium). For the in vitro part of the w...
