Dopaminergic diencephalospinal neurons (DDNs) are an evolutionarily conserved population of forebrain neurons that provide the primary source of dopaminergic (DAergic) innervation to the vertebrate spinal cord.
This year's Hugh Sinclair Lecture was delivered by Leena Peltonen (Sanger Centre, Hinxton, UK), who described the unique properties of highly conserved populations for mining the genome for complex traits.
First, conservation managers with limited resources at their disposal typically need to conserve populations of several threatened species.
Retaining and managing forest remnants would be a more effective strategy to conserve populations of these species.
But the authors are misguided in their belief that one way to avert a crisis is by conserving populations of wild bees, and even managing them where possible, to compensate for the continual loses of managed honeybees.
Our study suggests that habitat restoration in production forest landscapes is unlikely to play a significant role in conserving populations of species requiring slow-developing microhabitats, for decades if not centuries.
Given that larger experiments have produced little or no export [37] and that iron fertilization could have unintended consequences such as increases in toxic species [38], [39], conserving populations of large marine vertebrates may represent a more ecologically sound alternative.
It is possible, then, that the constrained ERK1/2 activity we observed in fetal tissue may be critical to conserve populations of progenitor cells in the fetal lung.
The availability and a better understanding of elephant genomes will facilitate efforts to conserve populations of these animals by enabling studies of behaviour, social organisation, population structure, genetic diversity and phylogeny.
Conserving populations in a broad range of habitat will likely be important for improving the stability of many fisheries, he says.
