Deviations from typical environmental conditions can provide insight into how organisms may respond to future weather extremes predicted by climate modeling. During an episodic and multimonth heat wave event (i.e., ambient temperature up to 43.4°C), we studied the thermal ecology of a ground-dwelling bird species in Western Oklahoma, USA. Specifically, we measured black bulb temperature (Tbb) a...
reports on distribution and abundance of bats from iran exist since mid-nineteen century, but studies on this subject are very scarce and have been conducted very infrequently by european biologists who visited iran occasionally. until now, six caves have been investigated and eight species of cave-dwelling bats have been reported from ilam province in south-western iran. the present paper has ...
Shrub-dwelling birds may resort to ground-foraging in the Sahel when opportunities are favourable. Several arboreal and semi-arboreal passerines, both African European, were frequently recorded foraging on ground, but not heavily grazed areas. Grazed, dry savannah probably has fewer insects which is often devoid of vegetation season. foraged more ground eastern Sahel, where grazing pressure low...

Gamma Coronaviruses (GCoVs) are distributed worldwide, affecting a wide range of bird species, the beluga whale, and bottlenose dolphins. Because of the limited proofreading capability in the viral encoded polymerase, they emerge genetically diverse. There has been no molecular surveillance data to describe the epidemiology of GCOVs in avian species. The present study was conducted to detect GC...
A survey on mite fauna of bird nests was carried out in Tehran, Golestan and Sistan & Baluchestan provinces in 2008. A total of 18 nests belonging to six bird species, namely Rock Dove Columba livia, House Sparrow Passer domesticus, Eastern Olivaceous Warbler Hippolais (Iduna) pallida, White-eared Bulbul Pycnonotus leucotis, Common Magpie Pica pica and Crested Lark Galerida cristata were collec...
چکیده به منظور بررسی اثر تنوع گیاهی و نوع منبع تغذیه ای بر تنوع و تراکم علفهای هرز و حشرات، کارایی مصرف نهاده ها ( نور، آب، عناصر غذایی) و عملکرد و خصوصیات کیفی چند گونه زراعی، آزمایشی به صورت کرتهای خردشده بر پایه طرح بلوکهای کامل تصادفی با سه تکرار در دو سال زراعی 1385-1384 و 1386-1385 در مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه فردوسی مشهد به اجرا درآمد. تیمارهای مورد بررسی دو منبع کود دامی و...
BACKGROUND The intracellular protozoan parasites of the genus Haemoproteus occur in different avian hosts all over the world. Various genus of blood sucking insects' families such as Hippoboscidae and Ceratopogonidae could transmit Haemoproteus in avian hosts. There are very limited number of studies on wild infected birds with blood parasites in Iran, so the aim of this study was to determine ...
Maryland's Green Infrastructure (GI) is a network of large, intact natural areas (hubs), interconnected by linear swaths of riparian or upland vegetation (corridors). The GI serves significant ecological functions and provides the bulk of the state's natural support system. This study examined whether the GI as mapped does, in fact, identify Maryland's most ecologically valuable forested lands,...
