Breeding

How can animals facing extinction be helped using modern science? Identification and description of the problem Extinction is referred to as the death of the last organism of a certain species; thus ending those organisms altogether. However, since most species are globally spread out this is something that takes careful consideration of every fact such as ‘is there a possibility the organism may have has a chance of survival somewhere unexpected?’(Hawking, 2012) Biologists have been trying…

the possibility of inbreeding depression. Genetic issues based on the life history of the parrot could also contribute. The bird mates for life and the average clutch size is between 2 to 4 eggs but the pairs don’t always successfully mate every breeding season. If a parrot loses its mate it may never try to find a new one meaning no new offspring adding to the genetic pool. It also takes 3 to 5 years for the young to reach…

Breeding gliders If you’ve ever wanted to do a fun animal hobby for a little extra money, then I would highly recommend breeding sugar gliders. Gliders look like exotic flying squirrels and originate from Australia. They are marsupials, and relate more to the term “flying possums” than flying squirrels. However, anyone interested in breeding gliders- or any other animal for that matter -must ask themselves this: “What does it take to breed sugar gliders, and am I really prepared to take on this…

The Red Panda, otherwise known scientifically as Ailurus fulgens, reproduces sexually and is generally shy and self-contained except when mating. Red Pandas become sexually mature at around 18 months and the approximate gestation period is around 130 days. Births typically occur in spring and summer, although the majority occur in June where the female will have anywhere from one to five cubs with the average being two cubs. The size of the litter, however, does not affect the gestation length…

within the Great Plains region of north-central Kansas weekly during breeding season of 12 weeks for 10 years (described in further detail below). My research team will observe twenty-five prairie dog coteries and their burrows (Hoogland 1995). The Great Plains area, the location in which we will…

include good management of the herd, pregnancy testing, and breeding soundness examinations of bulls. According to the Extension Extra from the South Dakota State University states, “percent calf crop is calculated by dividing the number of calves weaned by the number of females exposed during the breeding season” (Bongso,2009). One factor that affects loss in potential calf crop percentage is the failure of cows to become pregnant during breeding season. Extension Extra states, that there is…

Courtship and breeding periods can be identified by the observational studies of the frequency by circle-flying and collection of nest materials (Schuckard, R. 1994). King Shags are known to have a monogamous social system and commonly raise a single brood per year. Parents both share incubation of eggs, active roles in brood care and in chick feeding, as their nestlings are altricial (Schuckard, R. 2013). Roosting and breeding occur on a small number of islands, and they…

People do not always want barrow as they can’t not be used for anything such as only slaughter after the fair, and the gilts can also be kept on the farm to be bred. The decision becomes on Market or Breeding stock? Market pigs will be allowed to sell after the fair and breeding stock will not. Breeding stock will usually be born around November…

whales (The Orca Project). Often, whales are confined in small holding tanks with others that are foreigners to them. The matriarchal structure found in whale pods is diminished and as a result the whales often react in aggressive behaviors. SeaWorld breeding program is a serious problem and it is growing worse. SeaWorld owns 29 orcas; 23…

Some socially monogamous species follow a system of cooperative breeding, in which helpers within a group help assist in taking care of offspring of other parents. This increases the chance of survival of the offspring, and provides them with care such as grooming, training, and guarding. Because of the way that offspring are raised within cooperative breeding species, the fitness of offspring is greater than offspring who are not given aid by helpers. I will be discussing research done on this…
