Synteny indicates that the GPHs, Grem, and SOSD have been maintained in a common gene neighborhood throughout much of metazoan evolution.
First, in order to confidently rule out confounding environmental effects, common garden experiments need to start with the earliest ontogenetic stage of a given species (usually fertilized eggs, preferably from parents that have been maintained in a common garden).
Architecturally, it forms a warehouse in which taxonomic names from the prominent taxonomic data sources ITIS [ 22], NCBI [ 37] and Sp2000 [ 38] are replicated and maintained in a common structure.
The trees sampled in this study with provenances ranging from 59.6°N to 44.0°N (Additional file 1) have been previously described [ 27] and were maintained in a common garden at the University of British Columbia.
All animals were maintained in a common room under controlled temperature and a 14 h dark/10 h light cycle in the animal facility of the Biological Sciences Building at the Institute of Biomedical Research IIBB).
LCMV is primarily maintained in the common house mouse (Mus musculus and M. domesticus), but has also been reported among pet and research rodents, including hamsters and guinea pigs (1 ).
Each tree's seeds were divided into three groups: nursery growth studies, N; inoculation resistance studies R1, R2; and field resistance studies, F. Growth and resistance studies groups were maintained in a common location by different lab groups in this collaborative effort.
Twenty P. trichocarpa individuals from a population of approximately 450 individuals from the BC Ministry of Forests collection [ 27, 28] maintained in a common garden at the University of British Columbia were selected for xylem transcriptome analysis using the Illumina platform for ultrahigh-throughput RNA sequencing (RNA-Seq).
Although conclusive parentage analysis have not yet been performed for the marbled goby or the common goby, these observations hint at an interesting scenario in which male alternative reproductive tactics are important and maintained in certain lineages (sand goby, common goby) but not in other lineages such as the two-spotted goby and the marbled goby.
For small cage birds, a large cage or aviary allows for flight and space needed to reduce territorial stress that is often associated with common species maintained in captivity.
