گسترش نهشته هایی با سن دونین میانی- بالایی تا کربنیفر زیرین همانند بسیاری از نقاط دنیا در کشور ما نیز قابل توجه و اهمیت است. کشور ما که در این زمان بخشی از ساحل شمالی خشکی گندوانا را تشکیل می داده است در سرتاسر البرز از قسمت شرقی تا غربی و همچنین بخشهای ایران مرکزی و زاگرس در معرض پیشرویها و پسرویهای دریای شمالی پالئوتتیس قرار داشته است. در همه این نقاط این نهشته ها بر روی سطح فرسایش یافته رسوب...
Differential tolerance of low salinity, competition for nitrogen (N), and facilitation by altering N supply all may act to determine the pattern of seasonal succession of Enteromorpha intestinalis (L.) Link and Ulva expansa (Setch) S. and G. in estuaries and lagoons of southern California. Low salinity negatively affected both of these algae. However, when N was in sufficient supply, salinities...
Podocnemis expansa and P. unifilis present 2n = 28 chromosomes, a diploid number similar to those observed in other species of the genus. The aim of this study was to characterize these two species using conventional staining and differential CBG-, GTG and Ag-NOR banding. We analyzed specimens of P. expansa and P. unifilis from the state of Tocantins (Brazil), in which we found a 2n = 28 and ka...
This study was undertaken to determine the prevalence of anoplocephalid cestodes in sheep and goats in Senegal. Intestines of 462 sheep and 48 goats were examined; 47.4% of sheep and 6.2% of goats were infected. The species identified and their prevalence were, among sheep, Avitellina centripunctata 38.7%, Moniezia expansa 15.4%, Stilesia globipunctata 16.7%, and Thysaniezia ovilla 0.4%. Among ...
BACKGROUND Throughout Brazil a large number of people seek out reptiles for their meat, leather, ornamental value and supposed medicinal importance. However, there is a dearth of information on the use of reptiles in folk medicine. In North Brazil, the freshwater turtle, Podocnemis expansa, is one of the most frequently used species in traditional medicines. Many products derived from P. expans...
Thirty-eight specimens of free-ranging Podocnemis expansa (Amazon turtle) and 22 of P. unifilis (Tracajá) were screened for yeast isolation from surface (plastron, skin, and nails), eye, and mouth cavity. A hundred and eighteen yeast isolates belonging to 39 species were obtained. Debaryomyces hansenii, Candida galli, C. sake, and Rhodotorula mucilaginosa were the most frequent species isolated...
Nest site has influence on incubation duration and hatching success of two Neotropical turtles, the giant Amazon River turtle (Podocnemis expansa) and yellow-spotted side-neck turtle (Podocnemis unifilis--'Tracajá'). The 2000 and 2001 nesting seasons have been monitored at the Javaés River in Bananal Island, Brazil. Although they nest on the same beaches, there is a separation of the nesting ar...
گونه (c.presl.) fraser- jenkins & jermydryopteris expansa برای فلور سرخس های ایران از جنگل های پیسه سون، در جاده اسالم به خلخال در منطقه فیتوجغرافیایی هیرکانین گزارش می شود. مهم ترین صفت ریخت شناسی متمایزکننده این گونه، وجود راکیس و دمبرگ سفید رنگ، پهنک سه بار شانه ای، برگچه های مستطیلی، فلس هایی با نوار تیره تر در بخش میانی است. گونه dryopteris expansa مشابه گونه (hoffm.) a. grayd. dillat...
Polymesoda expansa spends a considerable portion of its life exposed to air in mangrove swamps where salinity fluctuates greatly. Thus, the aim of this study was to evaluate the effects of aerial exposure (transfer from 10 per thousand brackish water directly to air) or salinity changes (transfer from 10 per thousand brackish water directly to 30 per thousand seawater) on nitrogen metabolism in...
