Conservation genetic
| Question | Answer |
|---|---|
| Conservation genetics | The interdisciplinary subfield of population genetics that aims to understand the dynamics of gene flow in population to avoid extinction |
| Genome | An organism's complete set of DNA. A genetic blueprint of life |
| Gene flow | The context of speciation is the movement of alleles between populations through interbreeding and reproduction that can either impede or facilitate divergence |
| Genetic fitness | An organism's relative ability to survive, find a mate, and pass its genes onto the next generation |
| Epoch | A period of time in history, typically marked by notable events |
| Anthropocene | An unofficial unit of geologic time that describes the current period in Earth's history when human activity has become the dominant force shaping the planet's environment |
| How has biodiversity changed during the period of human influence | It has greatly decreased |
| What precent of animals in the world are actually wild? | 3% |
| What are the factors of species extinction? | New predators, more successful competitors, new diseases, environmental changes, habitat destruction, pollution, climate changes, single catastrophic event |
| What factors of species extinction can be most influenced by humans? | New predators (overhunting), environmental changes (human innovation), habitat destruction, pollution |
| Why should be preserve wild species genomes? | We can learn a lot about human health from animal genomes and use it for human medicine innovations |
| What is a good example of human medicine that came from wild species genomes? | GLP1s from gila monster venom, better understanding of tumors from Tasmanian Devil facial tumor disease |
| Low genetic diversity | Very few different genes in a population |
| What are other factors that can contribute population fitness? | Environmental factors, species temperament and behavior |
| How can environmental factors contribute to population fitness? | Habitat loss can lead to a decline in animal population |
| How can species temperament and behavior contribute to population fitness? | More aggressive animals might attack and kill each other |
| Main driver of current species loss | Environmental factors like habitat loss |
| Genetic diversity sequencing methods | Micro-satellietes, mitochondrial DNA (mtDNA), full genome sequencing |
| Vertebrate genomes project (VGP) | Collects DNA from the wild to be tests and publishes the findings |
| Micro-satellietes | Stretches of repetitive sequences unique to the genome |
| Advantages of micro-satellietes | Affordable |
| Disadvantages of micro-satellites | Time consuming, few sites uncertain |
| Mitochondrial DNA (mtDNA) | Sequenced from fossilized cells and is nuclear in nature |
| Advantages of mtDNA | Affordable |
| Disadvantages of mtDNA | Only shows maternal lineage |
| Full genome sequencing | Shows you everything about an animal's genetics |
| Advantages of full genome sequencing | Affordable, allows you to compare wild and captive samples, see trait diversity in different populations, show cross-breeds |
| Disadvantages of full genome sequencing | Technological limits |
| How does the information in genetic sequencing methods differ? | Micro-satellites have less information, mtDNA only shows the maternal side, and full genome sequencing shows you everything |
| How can information from genetic sequencing influence translocations? | Shows information on which animals are most genetically different from each other to avoid inbreeding |
| How can information from genetic sequencing influence environmental concerns? | Helps show genetic bottlenecks and inbreeding in animals |
| How can information from genetic sequencing help evaluate a new population? | Can show the genetic fitness of a population |
| How can information from genetic sequencing help in assessing behavior? | Some behaviors are developed from genetics and can be shown through sequencing |
| eDNA surveillance | Collect, barcode, and sequence DNA from wastewater symptoms to show what species and viruses are in a region |
| How can eDNA be used for monitoring? | It can show what species are in an area as well as the viruses that might be affecting them. It assists in species health and monitoring |
| What is so strange about a platypus? | They are mammals that lay eggs, have poisonous spurs, electro-sensing bills, missing most digestive enzymes we need |
| Why are we so interested in the platypus genetics? | Helps us understand specialization and they are losing genetic diversity |
| What are we evaluating with the eagle genome? | The genetic diversity of environmental subsets |
| Why are we so interested in eagle genetics? | To help determine resistance across genome variants and diversity in wind turbine strikes |
| What are we evaluating in bowhead whales? | Longevity and DNA repairing |
| Why are we so interested in bowhead whale genetics? | Helping humans live longer with our own genetics |
| What are we evaluating in sperm whales? | How the heavy metal accumlation of the Horizon oil spill is effecting them |
| Horizon oil spill | A very bad oil spill in the Gulf of Mexico that had a huge effect on the wildlife in that area |
| Why are we so interested in sperm whales? | To understand how their population structure has been effected as it declines |
| What are we evaluating in fishing cats? | How they have genetically evolved to smell fish, especially through odorant detection |
| eDNA | The genetic material an organism leaves behind in their surroundings |
