a list of 20 species of the subfamily tephritinae (diptera: tephritidae) from the urmia region (azarbaijan-e gharbi province, iran) is presented. the specimens were collected during 2005-2008 from six different localities. adults were obtained from overwintering and mature seed heads of 17 plant species of asteraceae. the species, urophora xanthippe (munro, 1934) is newly recorded for the fauna...

Point counts and mist-net surveys were employed to study the winter distri­ bution of nearctic migratory landbirds in Mexico’s Yucatan Peninsula. Overwintering mi­ grants comprised 42 regularly occurring species, and accounted for 30-58% (mean = 41%) of the individual birds encountered in surveys of a wide range of natural and disturbed habitats. Some migratory species were encountered most fre...

We report on the habitat associations of 21 species of grassland birds overwintering in or migrating through southern Texas, during 1991-1992 and 1992-1993. Ninety percent of our grassland bird observations were made during winter and spring, and only 10% occurred during fall. Grassland species made up a high proportion of the total bird densities in grassland and shrub-grassland habitats, but ...

Plasma glycerol and triglyceride levels and creatine kinase (CK) activity may increase during long-distance flights in migratory birds, but plasma profiles of these metabolites have not previously been reported for small birds during thermoregulation in cold climates. We measured early morning levels of plasma glycerol, triglycerides and CK activity in four species of small birds overwintering ...

there are 61 species in 14 families of fish-eating birds in iran. the fish-eating birds of the north of iran belong to 41 species in 10 families which include 67.2 percent of total fish eating bird species and 71% of fish-eating bird’s family of iran. resident birds constitute 13% of the fisheating birds of the caspian sea coasts and the rest are migratory in autumn and winter. there exist 3 ...

birds constitute the important elements of most ecosystems of the world. the objective of this study was to survey and identify birds of boujagh national park. for this reason the park divided into 7 parts and during 24 months, between autumn 1383 and late summer of 1385, the park has been surveyed. the results show that 234 species have been identified (about %46.4 of all bird species througho...

A new species, Haplothrips heliotropica, is described from Argentina causing severe damage to the leaves of Heliotropium amplexicaule (Boraginaceae), a South American plant that is now a serious weed of pastures in Australia. Observations are presented on the host specificity, seasonal population changes and overwintering of this thrips. The genus Haplothrips includes more than 230 species worl...
