2-9

Two arguments for managing wildlife

-UTILITARIAN arguments


- manage wildlife as means to help human beings achieve their ends


- ETHICAL arguments


- manage wildlife because its the right thing to do regardless of utility for us

utilitarian arguments stem from wildlife values

- GOODS: species recognized as tangible resources that human beings "consume"


- SERVICES: species that perform useful functions that benefit human beings


-INFORMATION: species that help human being gain knowledge and insight


- INSPIRATION: species that evoke wonder, awe and love from human beings

wild life as goods

-very small portion of the world's wild species are resources


-

wildlife provides ecological services

-decomposition, plant pollination, seed dispersal, pest control


-

wildlife as sources of information

-many discoveries that will improve human lives will come from studies of wildlife


- biotechnology

wildlife as inspiration

-attraction to wild species may be in our genes


-

Quantifying and Monetizing the value of wild life resources

- commodity values


- option values


-contingent values


- existence values


- bequestvalues

commodity values

what people are wiling to pay when there is market for species pay when there is a market for the species

option values

what people are wiling to pay to guarantee option of finding future use for species

contingent values

what people are willing to pay for the opportunity to use a species, even if they don't use it

existence values

what people are willing to pay to preserve a species, even if they never actually use it (or even see it)

bequest values

what people are wiling to pay to assure future generations have opportunity to use species

utilitarian cost-benefit dilemmas

-valuable species can lose out when costs of conserving it exceeds economic benefits of not conserving it


- only species with utilitarian value can be preserved


- have harmed many valuable species, so utility DOES NOT insure security

difficulty applying utilitarian argument to all wild species

- ignorance of all wild animals


- difficult to defend economically


-

ethical arguments

- do wild species also have intrinsic worth and right to exist ??


- removes burden of proving utility as a justification for conservation


-encompasses all species regardless of value to human beings


ethical arguments being quantified and monetized

- contradiction between not monetize intrinsic worth animals but humans monetize are able to do it for themselves


-

safe minimum standard

- argue that wild species should always be preserved unless costs of doing so are too high

wildlife and intrinsic worth

-unethical to harm or hurt wild species


-changes from economical issue to ethical one



- ethical motives for managing wildlife

1. anthropocentric


2. stewardship


3. biocentric


4. ecocentric



anthropocentric


-only humans are worthy of ethical treatment


- only unethical if species loss negatively impacts human beings

stewardship

- religious basis (take care of divine creation)


- human beings are "highest forms" of life and have to take care of other species because of it


- human needs come first because of higher position in nature

biocentric

- appreciation for life


- human beings are equal to individuals of other species


- moral basis for animal rights movement



ecocentric

- human behavior should not threaten other species or habitats


- Aldo Leopold ( all species should be allowed to exist regardless of the presence or absence of economic advantage


- support moral code of ethics

- age structure


- life history stages

population

group of organisms of the same species in the same area at the same time


Community

- all organisms of all species in the same area at the same time

ecosystem

all organisms in an area and their physical environment

Geographic ranges

- native


- endemic


- exotic


- invasive

native

- found naturally in a place (indigenous)

endemic

- found only in a particular place

exotic

brought to a place by human activities (non-native to environment )

invasive

an exotic species that has successfully invaded a native community

dispersion patterns

-clumped


- uniform


- random

population size

number of individuals in a population

population density

number of individuals per unit area

dispersal movements

- one-way movements from one place to another, often from birth to breeding


- immigration: individuals moving into a population from some other population


- emigration: individ. leaving a population and moving to another population


-

natality

- birth rate, number of births per individ. per unit time



mortality

death rate, number of deaths per individ. per unit time



survival

proportion of individ. alive at one period that are still alove sometime later

age at first breeding

-mean age at which females first begin to produce young

- small animals breed earlier in life, larger animals breed later


physiological longevity

genetically fixed maximum age for species



ecological longevity

-age at which most animals in a wild population die under natural conditions



reproductive span

-period of animal's life span during which it is capable of reproducing

- positively correlated with longevity and body size




frequency of breeding

- many species breed annually, but some breed at shorter or longer intervals

- annual or less frequent closer to the poles


- smaller animals breed more frequently, larger animals less

age structure


- number of individ. in each age class in a population

- age classes vary in vulnerable to mortality


- relative number of older vs. younger individ. tells us whether population is increasing, stable. or decreasing


survivorship curves

Type 1

Type 2


Type 3


Type 1

-greates mortality risk occurs as old age

type 2

habitat fragmentation

subdivision of the remaining habitat into smaller, more isolated areas



types of species that are sensitive
