the data used in this research were according to survival rate records of 9700 lambs from 735 rams and 8082 ewes, which collected at moghani flock breeding research station during the year 1365 to 1390. the frequency distribution causes of culling and survival distribution function of lambs to yearling age were estimated by sas (2000). results revealed that 49.81 percent of total lambs were cul...

Effects of soil condition and burial on boll weevil, Anthonomus grandis grandis Boheman, mortality in fallen cotton, Gossypium hirsutum L., fruit were assessed in this study. During hot weather immediately after summer harvest operations in the Lower Rio Grande Valley of Texas, burial of infested fruit in conventionally tilled field plots permitted significantly greater survival of weevils than...

The persistence of atmospheric circulation anomalies over East Asia shows a winter to winter recurrence (WTWR) phenomenon. Seasonal variations in sea level pressure anomalies and surface wind anomalies display significantly different characteristics between WTWR and non-WTWR years. The WTWR years are characterized by the recurrence of both a strong (weak) anomalous Siberian High and an East Asi...

To evaluate the relationships between coral calcification, thermal stress, and sedimentation and eutrophication linked to human impact (hereafter referred to as "land development") by river discharge, we analyzed growth characteristics in the context of a paleoenvironment that was reconstructed from geochemical signals in modern and fossil (1.2 cal kyr BP and 3.5 cal kyr BP, respectively) massi...

Impacts of livestock grazing in arid and semiarid environments are often concentrated in and around wetlands where animals congregate for water, cooler temperatures, and green forage. We assessed the impacts of winter-spring (November-May) cattle grazing on marsh vegetation cover and occupancy of a highly secretive marsh bird that relies on dense vegetation cover, the California Black Rail (Lat...

licensed dairy farms in the central region of Fars province were randomly selected in order to participate in aseasonal prevalence study. A cross-sectional study was designed to determine prevalence at cow and quarterlevel based on clinical signs for clinical mastitis and indirect tests for subclinical mastitis. 6180 quarters from1545 dairy cows were tested by clinical examination and Californi...
