BACKGROUND: Restricted space and close contact with conspecifics in captivity may be stressful for musk deer, as they are highly territorial and solitary in the wild. So we tested the effects of crowding on stress of forest musk deer (Moschus berezovskii) in heterosexual groups, using fecal cortisol analysis as a non-invasive method. 32 healthy adults during non-breeding seasons were chose as our experimental objects. Group 1 was defined as higher crowding condition, with 10-15 m²/deer (6 enclosures, 10&amp;#9792; and 6&amp;#9794;); group 2 was defined as lower crowding condition, with 23-33 m²/deer (6 enclosures, 10&amp;#9792; and 6&amp;#9794;). Every enclosure contained 1 male and 3 female. These patterns had been existed for years. RESULTS: The results...

Autores: Huang,Xiaoyun; Liu,Gang; Zhang,Weiwei.
ABSTRACT LOB (lateral organ boundaries)-domain proteins deﬁne a family of plant-speciﬁc transcription factors involved in developmental process from embryogenesis to seed production. They play a crucial role in shaping the plant architecture through coordinating cell fate at meristem to organ boundaries. Identification of LBD genes from Brassica rapa genome, and analysis of phylogeny，gene structure, chromosome location, phylogenetic and tissue expression pattern analysis of LBD family genes in Chinese cabbage will be useful to the functions identification of plant LBD genes. Based on Brassica rapa genome database and bioinformatic method, Chinese cabbage LBD family genes were identified and the genes were sequenced. A phylogenetic tree was created using...

Chronofunctions of Heilu soil developed from Loess in Luochuan, on the chinese Loess plateau
Provedor de dados: 90
Autores: Liu,Gang; Xu,Wennian; Cai,Chongfa.
Soil chronofunctions are an alternative for the quantification of soil-forming processes and underlie the modeling of soil genesis. To establish soil chronofunctions of a Heilu soil profile on Loess in Luochuan, selected soil properties and the 14C ages in the Holocene were studied. Linear, logarithmic, and third-order polynomial functions were selected to fit the relationships between soil properties and ages. The results indicated that third-order polynomial function fit best for the relationships between clay (&lt; 0.002 mm), silt (0.002-0.02 mm), sand (0.02-2 mm) and soil ages, and a trend of an Ah horizon ocurrence in the profile. The logarithmic function indicated mainly variations of soil organic carbon and pH with time (soil age). The variation in...
