Comparative analyses by scientists at the Swiss Institute of Bioinformatics and other institutions of 76 arthropod species spanning 500 million years of evolution reveal genomic changes that point to ...
Trees in tropical forests are well known for removing carbon dioxide from the air and storing the potent greenhouse gas as carbon in their leafy branches and extensive roots. But a new analysis led by...
Laid on leaves hanging over streams in tropical rainforests, glassfrog eggs are tasty snacks for snakes, insects and other predators until they hatch and drop into the streams to begin life as tadpole...
Three draught horse breeds are maintained in the Czech Republic: the Silesian Noriker (SN), the Noriker (N), and the Czech-Moravian Belgian (CMB). Because the SN and CMB populations are currently clos...
Legendary conservationist Aldo Leopold once advised: "To keep every cog and wheel is the first precaution of intelligent tinkering." For the Endangered Florida Scrub-Jay, new research shows that ...
Native duck populations have lower productivity, and have not been developed as much as commercials duck breeds. However, native ducks have more importance in terms of genetic diversity and potentiall...
The genetic relationships between different populations and breeds of exotic dairy goats in Thailand were studied using 12 microsatellite markers. Blood samples were obtained from 211 goats from Depar...
A study was conducted to assess the genetic diversity among Simmental Cross cattle in West Sumatra using microsatellite DNA markers. A total of 176 individual cattle blood samples was used for obtaini...
The maternally inherited mitochondrial DNA (mtDNA) D–loop region is widely used for exploring genetic relationships and for investigating the origin of various animal species. Currently, domestic duck...
sumed by mammals (e.g.Brosimum alicastrumandAmpelocera hottlei) increased in their abundance in TE plots. Rarefaction curves showed that species diversumed by mammals (e.g.Brosimum alicastrumandAmpel...
In contrast to high genetic diversity of mitochondrial DNA (mtDNA), equine Y chromosome shows extremely low variability, implying limited patrilines in the domesticated horse. In this study, we applie...
Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and subsequent sub-cloning and sequencing were used in this study to analyze the molecular phylogenetic diversity and spat...
The genetic diversity of native chicken populations from Myanmar, Thailand, and Laos was examined by using 102 insertion and/or deletion (indels) markers. Most of the indels loci were polymorphic (71%...
Many insights into ecological and evolutionary processes have come from studies of island systems. Diversity, abundance, and movement of species are restricted on smaller islands, but these dynamics c...
Aspects of the behavioral ecology of bird song learning are examined in three parts. First, an approach from image analysis is extended to allow rapid, quantitative description of animal sounds. In th...
