Abstract:
... A palynological study was performed on a 2m thick sediment sequence recovered from Mire Kupena (1356m), a former lake in the Western Rhodopes Mountains (south Bulgaria) and supported by radiocarbon dating. The record extends back to ca. 30,000cal. yrs. BP (Middle Pleniglacial) when the study area was occupied by wooded steppe composed of Pinus sp., Pinus peuce, some Betula, Juniperus, and cold-tol ...

During virus surveys of bean plots in the south central region, we identified an isolate of Clover yellow vein virus (ClYVV), designated ClYVV 11B, by indirect ELISA and RT‐PCR causing severe mosaic symptoms and systemic necrosis. Indirect and direct ELISA using ClYVV antisera differentiated the ClYVV isolate from Bean yellow mo ...

It is generally believed that a high quality queen should have the following physical characteristics: high live weight; high number of ovarioles; large size of spermatheca; high number of spermatozoa in spermatheca; and be free from diseases and pests. It is, however, also kn ...

Unlike other ectoparasites, they are attached to the body of their host only when they need to feed, otherwise they stay in refugia in bat roosts. Consequently, they are often overlooked by bat specialists and in many countries they are either unknown or poorly characterized. This study reports re ...
