A total of 1,794 migrating birds trapped at a coastal site in southern Sweden were sampled for detection of Campylobacter spp. All isolates phenotypically identified as Campylobacter jejuni and a subset of those identified as non-C. jejuni were identified to the species level by PCR-based techniques. C. jejuni was found in 5.0% of the birds, Campylobacter lari was found in 5.6%, and Campylobact...
Genetic Control of Water and Nitrate Capture and Their Use Efficiency in Lettuce (Lactuca sativa L.)
Robustness in lettuce, defined as the ability to produce stable yields across a wide range of environments, may be associated with below-ground traits such as water and nitrate capture. In lettuce, research on the role of root traits in resource acquisition has been rather limited. Exploring genetic variation for such traits and shoot performance in lettuce across environments can contribute to...
-We studied the effects of forest patch size and habitat characteristics on breeding success of Scarlet Tanagers (Piranga olivacea) in western New York in 1995 and 1996. Twenty forest stands were grouped into four size classes: Group I (<10 ha, n = 6), Group 11 (10 to 50 ha, n = 7), Group III (>50 to 150 ha, n = 5), and Group IV (>1,000 ha, n = 2). Group I, II, and III sites were habitat patche...
Humans obtain a number of products from animals. These include food, clothing, medical materials, companionship and research knowledge to name a few. A valued ethic contends that it is inappropriate for one to treat another as a means to an end. In short, it is wrong to treat another as simply a product. Historically, non-human beings have not been included as “others” and thus their treatment ...
Documentation of humpback whale migratory movements between Australasia and the Southern Ocean has been limited almost exclusively to historical whaling data. This study examines photographic evidence documenting three individual whales their breeding grounds on northeast coast Australia feeding in Area V Ocean. Although these individuals exhibited marked site fidelity same low latitude grounds...
main perennial rivers of gujarat, tapi, narmada, mahi and sabarmatiare meeting arabian sea in gulf of khambhat. the out flow of mahi river intothe sea is decreased due to construction of dams like bajaj sagar, kadana, panamand wanakbori weir. so, tidal effect of sea and sea water intrusion is beingincreased on landward side. moreover, due to erratic nature of rainfall andimproper management of ...
Poplars are fast-growing, high-yielding forest tree species, whose cultivation as second-generation biofuel crops is of increasing interest and can efficiently meet emission reduction goals. Yet, breeding elite poplar trees for drought resistance remains a major challenge. Worldwide breeding programs are largely focused on intra/interspecific hybridization, whereby Populus nigra L. is a fundame...
