Effect of uneven sampling along an environmental gradient on transfer-function performance
We investigate the effect that uneven sampling of the environmental gradient has on transfer-function performance using simulated community data. We find that cross-validated estimates of the root mean squared error ...
Gene expression in bryozoan larvae suggest a fundamental importance of pre-patterned blastemic cells in the bryozoan life-cycle
(BioMed Central, 2011-06-06)
Background: Bryozoa is a clade of aquatic protostomes. The bryozoan life cycle typically comprises a larval stage, which metamorphoses into a sessile adult that proliferates by asexual budding to form colonies. The homology ...
Ciliary photoreceptors in the cerebral eyes of a protostome larva
(BioMed Central, 2011-03-01)
Background: Eyes in bilaterian metazoans have been described as being composed of either ciliary or rhabdomeric photoreceptors. Phylogenetic distribution, as well as distinct morphologies and characteristic deployment ...
Histone variant innovation in a rapidly evolving chordate lineage
(BioMed Central, 2011-07-15)
Background: Histone variants alter the composition of nucleosomes and play crucial roles in transcription, chromosome segregation, DNA repair, and sperm compaction. Modification of metazoan histone variant lineages occurs ...
Genomic features and computational identification of human microRNAs under long-range developmental regulation
(BioMed Central, 2011-05-27)
Background: Recent functional studies have demonstrated that many microRNAs (miRNAs) are expressed by RNA polymerase II in a specific spatiotemporal manner during the development of organisms and play a key role ...
Retention of Coastal Cod Eggs in a Fjord Caused by Interactions between Egg Buoyancy and Circulation Pattern
(American Fisheries Society, 2011-08-01)
Norwegian coastal cod form a stationary population of Atlantic cod Gadus morhua consisting of several genetically separated subpopulations. A small-scale differentiation in marine populations with pelagic eggs and larvae ...
