BIOL378 - SARA EXAM ACTUAL QUESTIONS AND ANSWERS
WITH COMPLETE SOLUTIONS VERIFIED LATEST UPDATE
Current status of species extinction
1000x natural baseline rate, 6th mass extinction
What is field of conservation biology
Aims to understand and alleviate species decline and loss, encompasses social science
as it's a value-driven field
Why does conservation change with values
Value driven field, that changes with peoples values and attitudes towards the problem
at hand
Values driving conservation
Ecosystem services, intrinsic (right of species to exist) and extrinsic values (utilitarian),
ethical responsibility, biodiversity value
What are ecosystem services?
the benefits people obtain from ecosystems and the organisms in it
What are the four ecosystem services
provisioning, regulating, cultural, supporting
Western views often ignore.. they are important because?
Traditional and indigenous views they value the cultural importance of species and
believe ecosystem services to be a two way relationship
What does it mean value driven field
, Funding and research is put towards what peoples attitudes and values are over the
issues/problems
What species traits are linked to higher likelihood of extinction
Slower generation times, lower reproduction rate, small population sizes, limited
geographic range, specialists, limited dispersal
Problems with cultural ecosystem services
They differ significantly between people which can lead to conflict and disagreements
Potential solutions with the classification of cultural ecosystem services
Involving indigenous views in the framework behind decision making, results in more
diverse and inclusive views and better management strategies
Hawaii cultural framework
Knowledge, spirituality, social interactions and physical and mental well-being
Maori perspective of ecosystems
Cultural values come before and underpin ecosystem services
Ecological extinction means
Numbers are so low that the organism/species no longer significantly contributes to the
ecosystem or interactions with other species - I.e only exist in captivity
Why should we care about ecological extinctions
Tropic cascades, biodiversity loss, loss of ecosystem function
What does non-random species loss mean
Deviates from the expectation that extinctions occur randomly, Suggests that some
species are more likely to go extinct than others due to various factors
What is species triage
