My interests in the life sciences are very broad and cover many different disciplines -- including genomics, cytogenetics, cell biology, morphology, behaviour, physiology, developmental biology, ecology, and palaeontology -- all linked by the unifying theme of evolution. Although my primary research focus is on genome evolution, I consider myself a biologist first, an evolutionary biologist second, and a genome biologist third. Most of my undergraduate education was based in organismal biology such as behaviour and physiology; my interest in genome evolution developed somewhat later, during the early stages of my graduate program, and has only increased since then. Nevertheless, I maintain a keen interest in the biology of organisms, and have sought to integrate genomics and organismal biology as much as possible in my research. In keeping with this, I am currently working to build a Division of Genomic Diversity within the Biodiversity Institute of Ontario, which will create further links between the study of genomes and of the organisms in which they reside. In the most general terms, my research focus can be described as the evolution of genomes at large. In particular, my primary topic of study in this regard is the "C-value enigma" less appropriately but still more commonly dubbed the "C-value paradox" , the complex puzzle relating to variation in nuclear genome sizes among eukaryotes. In animals alone, nuclear DNA contents vary more than 3,fold, with this variation bearing no relationship to the number of genes. A complete understanding of how and why genomes vary so much in size has remained elusive for more than half a century, and has become a more timely issue than ever in the post-genomic era. To address the causes and consequences of variation in genome size, my lab makes use of the compiled data in the Animal Genome Size Database a comprehensive catalogue of nearly 4, animal genome sizes which I assembled in as well as large numbers of original estimates from a range of taxa. Using these broad datasets, we are conducting comparative analyses of genome size variation in different groups of both vertebrates and invertebrates in order to elucidate the general patterns of distribution among taxa and the relationships between genome size and diverse cellular, organismal, and ecological parameters e. In terms of original data, our primary focus is on invertebrates, which are badly understudied from the perspective genome size variation. Recent and current groups of particular interest include insects, spiders, crustaceans, molluscs, echinoderms, and annelids. More broadly, I am also interested in the evolution of key genomic components, especially transposable elements, that contribute substantially to genome size diversity.

We are also interested in exploring linkages in both directions between ecology, environment, and evolution at the organism level with patterns and processes of molecular evolution. To do well you need to understand and apply the concepts taught, not just brute memorization.

I am an evolutionary biologist specializing in genome size evolution at the University of Guelph in Guelph, Ontario, Canada. Be sure to visit Evolver Zone. Jan 14 comment s. This past May, I was fortunate enough to take part in a conference in Venice, Italy, which was a retrospective on the legacy of famous paleontologist and author Stephen Jay Gould 10 years after his death.

I don't know if something has happened, but when I took he one of the better lecturers, and now it's just the total opposite Patterns of genome size diversity in the ray-finned fishes. Had worse but stultifyingly boring and unhelpful in lectures. No offense, but for such an easy topic you sure managed to find a way to make it difficult. Large-Scale Genome Evolution In the most general terms, my research focus can be described as the evolution of genomes at large. Using these broad datasets, we are conducting comparative analyses of genome size variation in different groups of both vertebrates and invertebrates in order to elucidate the general patterns of distribution among taxa and the relationships between genome size and diverse cellular, organismal, and ecological parameters e. For Credit: Yes. It's all "Omicron". In keeping with this, I am currently working to build a Division of Genomic Diversity within the Biodiversity Institute of Ontario, which will create further links between the study of genomes and of the organisms in which they reside. Several non-mutually-exclusive possibilities: 1. Complicated but I wouldn't take him again. This technique combines the advantages of more traditional methods like scanning densitometry and flow cytometry, and provides an efficient and comparatively inexpensive means of quantifying nuclear DNA. Gregory, T. Aug 6th,

Gregory completed his B. He has broad interests in the life science, including genomics, cytogenetics, cell biology, morphology, behaviour, physiology, developmental biology, ecology, and palaeontology -- all linked by the unifying theme of evolution. His main research focuses primarily on the issue of genome size evolution the " C-value enigma " in animals and the origins and biological significance of " junk DNA ".

I reserve the right to be horrified by the death, suffering, grief, fear, or abuse of any humans regardless of nationality, faith, language spoken, sex, gender, sexual orientation, skin colour, age, socioeconomic status, disabilities, or any other factor that is used to divide. Recent and current groups of particular interest include insects, spiders, crustaceans, molluscs, echinoderms, and annelids. Andrews, C. Website links:. Honestly worst thing I ever took at uni, content v interesting but horrendously taught. In order to understand the massive variation in eukaryotic genome sizes, it is necessary to acknowledge the genome itself as a level of biological organization forged by evolutionary processes acting at lower levels i. COVID is no worse than flu. Dec 21st, For example, I have worked to increase cooperation and conceptual understanding between zoologists and botanists, between genome sequencers and genome sizers, and even between genome biologists and palaeontologists.
