Immunization with OPN5 increased seasonal degradation of reproductive activity in Magang ganders.

College of Animal Science and Technology, Hunan Agricultural University, Changsha 410128, China. Electronic address:
To investigate the regulatory mechanism mediated by hypothalamic OPN5 on seasonal changes in the reproductive activities of domestic geese, 60 Magang ganders in their breeding period were selected for the experiment and evenly divided into an immunization group(OPN5-IM) and a control group. On days 0, 15 and 30, ganders in the immunized group were immunized with OPN5-KLH protein vaccine, and ganders in the control were immunized with the same amount of blank emulsified vaccine. Additionally, 120 female geese were provided to stimulate the reproductive activities of male geese.

Electronic address:
Air pollution is highest in winter. The high concentration of particulate matter (PM) and trace elements (TE) after the growing season is influenced by increased pollutant emissions, unfavorable meteorological conditions, and the low efficiency of air phytofiltration. Plants that can remove pollutants from the air during the growing season are leafless in autumn/winter, and therefore unable to capture PM/TE effectively.

Phenology is a major component of animals' breeding, as they need to adjust their breeding timing to match optimal environmental conditions. While the effects of shifting phenology are well-studied on populations, few studies emphasise its ecological causes and consequences at the inter-individual level. Using a 20-year monitoring of more than 2500 breeding events from ~ 500 breeding little penguins (Eudyptula minor), a very asynchronously breeding seabird, we investigated the consequences of late breeding on present and next breeding events.

Soil Science Faculty, Lomonosov Moscow State University, Moscow, 119234, Russia.
Extracellular hydrolytic activity (phospholipase, protease and hemolysin production) was evaluated in 178 strains of potentially pathogenic ascomycetous (Candida parapsilosis, Candida tropicalis) and basidiomycetous (Rhodotorula mucilaginosa) yeasts isolated from the excreta of Mew Gulls. Two bird colonies, one nesting in a natural habitat and the other in an urban habitat at the landfill, were studied simultaneously during their 7-month breeding season. Significant differences in phospholipase and protease production were found between natural and anthropophized strains.

For sustainable genetic improvement of crops like sorghum, assessing genetic variability and knowing the nature and extent of the association between grain yield and yield-related traits is a prerequisite. However, there needs to be sufficient information about the genetic variability study as well as yield-related trait correlation and path coefficient analysis for sorghum accessions, especially those from southern Ethiopia. Hence, this field experiment assessed genetic variability, determined the nature and extent of phenotypic-genetic correlation, and analyzed the path coefficients among 17 quantitative traits.
