Activities. |
|
| |
1. |
Introduction
- what are biodiversity and biosecurity?. |
|
| |
|
Read
the fact sheets "What is marine biodiversity?"
and "The organisational structure of marine biosecurity
in New Zealand".
In
groups or as a class, discuss, create, and display definitions
of biosecurity and biodiversity.
|
|
| |
2. |
Why
is marine biodiversity important?. |
|
| |
|
Individually
or in small groups, choose one or more of the following
marine biodiversity issues to investigate, using the fact
sheets as starting points. |
|
| |
|
|
|
Research
the potential of New Zealand marine species, for example,
for pharmaceuticals or food grown in marine farms. (You
may also find useful information on NIWA's Aquaculture
Update Online[www.niwa.co.nz/pubs/au/archive].) |
|
| |
|
|
|
Research
Maori, Pakeha, and other cultural views on the importance
of the biodiversity and conservation strategies practised
historically by Maori and other cultures. |
|
| |
|
|
|
Create
a visual display of New Zealand's marine biodiversity
to show the range and uniqueness of our marine flora and
fauna. Use a colour key code to show those species that
are endangered because of exploitation or introduction
of exotic species. Indicate the effects that those endangered
species are experiencing. |
|
| |
3. |
The
ways in which human activities impact on marine diversity. |
|
| |
|
Individually
or in small groups, choose one or more of the following
marine biosecurity issues to investigate, using the fact
sheets as starting points.
Possible
issues to investigate:
|
|
| |
|
|
|
Research
the food web for a group of species. Look at what impact
the accidental introduction of the northern Pacific seastar
could have on the food web. |
|
| |
|
|
|
Research
and graph the tolerance limits of one or more exotic species
(for example, water temperature ranges). Map where the
exotic species could become established in New Zealand
waters and highlight which marine industries and fisheries
or nursery areas it/they could impact on. |
|
| |
|
|
|
Research
why one or more exotic species are so successful, considering
life cycle (speed of reproduction), adaptations, and the
absence of natural enemies (predators, parasites, and
pathogens). |
|
| |
|
|
|
Algal
blooms - research the nature of the "boom and bust"
cycles that occur naturally and the impact of algal blooms
on marine farming or biodiversity. |
|
| |
|
|
|
Undaria
- pest or opportunity? Investigate the cost of controlling
undaria and compare it with the potential benefits from
farming it and exporting it to Japan, where it is a food
source. |
|
| |
|
Students
should aim to process information to discuss the impact
of human activities on the New Zealand marine ecosystem. |
|
| |
|
|
|
Processing
information will involve analysing data and information
from primary and/or secondary sources. |
|
| |
|
|
|
The
human activities could be the introduction of exotic species. |
|
| |
|
|
|
Consideration
of the impact of the human activities could involve:
outlining
the effects
outlining
the implications
evaluating
the options
suggesting
alternatives
stating
opinions
making
judgments
justifying
decisions
projecting
future consequence
|
|
| |
|
The
processed information could be presented as a written
report, oral report, newspaper article, seminar, poster,
website, multimedia presentation, and so on. |
