Ring-necked snakes (Diadophis punctatus) are suspected of being venomous because their Duvernoy's gland secretions have high levels of phospholipase activity, which is characteristic of many viperid and elapid venoms, and because anecdotal reports of feeding behavior are consistent with the use of a venom. We tested the toxicity of northwestern ring-necked snake oral secretions to a natural pre...

The forests in Sardasht area in the West Azarbaijan Province were quantitatively studied in this research. Based on Importance Value Index, in general, two types of forests have been identified: Quercus libani Oliv. in the northern, northeastern and northwestern aspects and Quercus brantii Lindl. in the southern, southeastern and southwestern and eastern aspects.

The call characteristics and distribution of blue whales in the North Pacific were examined by use acoustic surveys. Two distinct vocalisation types have been previously attributed to from limited regions (cf. Thompson Friedl, 1982; Rivers, 1997). Hydrophone data sixteen sites for these whale vocalisations. There geographic seasonal differences between occurrence two types. hydrophones that mor...

Wolves (Canis lupus) in North America are considered obligate predators of ungulates with other food resources playing little role in wolf population dynamics or wolf prey relations. However, spawning Pacific salmon (Oncorhyncus spp.) are common throughout wolf range in northwestern North America and may provide a marine subsidy affecting inland wolf-ungulate food webs far from the coast. We co...

OBJECTIVE The authors hypothesized that psychiatric liaison screening of elderly patients with hip fractures would shorten the average length of hospital stay and increase the proportion of patients who returned home after discharge. METHOD The study was performed at Mount Sinai Medical Center in New York and Northwestern Memorial Hospital in Chicago. The subjects were 452 patients 65 years o...

Teaching and learning about a big idea, “the structure of an atom” has been an important topic in science education. Nevertheless of the importance of the big idea, studies show student alternative conceptions and learning difficulties. Moreover, those alternative conceptions had been identified in textbooks, curriculum materials, and instructions provided by science teachers. In a study of stu...
