- Bats migration and Hibernation
- Habitat Selection
- Barbary Macques Bonding
- Causes of Dispersal at ultimate level
- Genes and the Environment (Nature versus Nurture)
- a the reasons may not be so immediately apparent
- b choosing a place to live, which
does not necessarily imply a conscious choice or that individuals
make a critical evaluation of all of the factors. More often the
choice is an automatic reaction to key aspects of the environment
- c Most bats hibernate.
Some bat species do migrate - most often to and from caves used
as hibernation sites. Some little brown bats migrated over 200 km
from hibernation caves in Vermont to summering sites in
- d If two animals reared from birth under identical environments
differ in habitat preference when adults, the conclusion would be
that the differences resulted from hereditary factors
- e male Barbary macaques have a better chance of bonding with each other when at least one is hauling
around an infant. the infant is used as a social tool-- the males however also have high stress levels because the children can get annoying
5 Multiple choice questions
- Northern elephant seals make two round-trip migrations per year
travelling up to 21,000 km during the 250-300 days they are at-sea.
Males migrate further than females.
- African wild dogs are cooperative
breeders living in packs of up to
20. Some will stay back and
protect the pups while the rest
- most mammalian social systems are arrange matrilinearlly; mothers and their offspring may stay together and groups are this composed of mothers, daughters, aunts, and nieces
- Members of dense colonies are much more at risk of spreading
parasites or disease simply based on density and proximity.
- matings between members of different populations within
a species leads less-fit offspring. . Members of a population may possess adaptations to local
conditions that are potentially lost through outbreeding.
Two areas may differ in temperature, humidity, or types of food
and if each population is genetically adapted to these conditions
they would be better off mating with individuals with those same
5 True/False questions
Interference with Reproduction → It manifests itself through reduced reproductive success and
survival of offspring from closely related parents compared to
offspring of unrelated parents.
It is caused by increased homozygosity of the inbred offspring
and the resulting expression of deleterious recessive alleles.
Lion Dispersal Pattern → Because of the prevalence of polygyny, and associated tendency for males to disperse as they reach maturity, adult males are generally not related to other adults in the group. Males leave before they reach the age of maturity (sexually) and fathers leave before their daughters reach the age of maturity
Eusociality → 1. Cooperative care of the young
2. Reproductive castes with non-reproductive members
caring for reproductive nest mates
3. Overlap between generations such that offspring assist
parents in raising siblings
Moose and Deer Habitat Home → Sheep habitats consist of stable, long-lasting grass
communities that exist in small patches where knowledge of
location and predator avoidance is crucial.
Inbreeding Immunity → Many species of seals and sea lions migrate thousands of kilometers each year from island breeding and molting sites to feeding areas.
