Flashcards in Bio camp inv Deck (31):
Define Biodiversity hotspots
The richest an most threatened reservoirs of plant and animal life on earth
What are the three levels of biodiversity?
What are 6 human activities that have led to a decline in our native fauna?
Burning fossil fuels
What is the impact and biological consequence of urbanisation on our wildlife?
Loss of habitats:
- Shelter and protecting
replacement of specialist with generalist species, thus leading to biotic homogenisation
What is the impact and biological consequence of Deforestation on our wildlife?
Loss of habitats:
- Shelter and protecting
by separating contiguous areas of rainforest from each other, by interfering with plant reproduction, and by exposing organisms of deep forest to “edge” effects
What is the impact and biological consequence of Introduced species/disease on our wildlife?
Increase in competition
These new pressures have also caused a major impact on our country's soil and waterways and on its native plants and animals.
Feral animals impact on native species by predation, competition for food and shelter, destroying habitat, and by spreading diseases.
What is the impact and biological consequence of Hunting on our wildlife?
Reduction in species population but increase in the population of lower tier species if the animals hunted are the top predators.
What is the impact and biological consequence of Burning of fossil fuels on our wildlife?
Excess of CO2 in the air kills plants especially, which ultimately will begin to kill of the animals as if there are less plants there will less food the animals
fossil fuel extraction results in noise disturbance, pollution of surrounding air, water, and lands, and destruction of forests and other landscapes that make them unfit for sustaining wildlife populations
This leads to warming of the oceans, which has drastic impacts on marine life. Higher temperatures cause oceanic acidification that result in coral bleaching
What is a conservation program aimed at maintaining biodiversity of fauna in WA?
List three steps involved in the conservation program.
Breeding and reintroducing native animals
Eradication of feral animals
- poison baiting
- 1080, poison pea (Eradicat) which is dropped by aircrafts
Educating the community
What are three types of traps used for monitoring animal species?
What types of animals does the sheffield trap catch?
What types of animals does the elliot trap catch?
What are two other non-trapping methods?
What are the 5 criteria used for the study of populations?
What are ID tags for?
To see if there are new animals bred in the area
Why are animals weighed and head (L/W) measured?
to see their health, age and growth (if recaptured)
What is found in the upper story of the Jarrah forest?
Tawny frog mouth
What is found in the middle story of the Jarrah forest?
What is found in the under story of the Jarrah forest?
What is the dominant soil type in this area?
What is the climate of SW of WA experience?
has a Mediterranean climate, with dry summers and wet winters. Mean maximum daily temperatures range from 16 °C (60.8 °F) in July to 34 °C (93.2 °F) in February.
What is the annual average rainfall here in The jarrah forest of mundaring?
Annual rainfall (1,300 millimetres) on the scarp than inland or to the north-east (700 millimetres)
Why are woylies important to the ecosystem?
They can store food items in their cheek pouches for later caching or eating.
As a result, Woylies contribute significant ‘ecological services’ to areas they inhabit, as they disperse plant seeds and fungal spores.
Their diggings also increase water infiltration to the soil, and allow seeds and organic matter to be trapped, facilitating plant recruitment.
What are some special adaptations of echidnas?
They have a mammary duct, where milk oozes out and the puggle licks it up
They roll up into a ball as defence
Echidnas are monotremes, or mammals that lay eggs
What are some adaptation of the prickly moses?
They fix nitrogen in the soil, which acts like fertiliser
produce a lot of seeds, and release alot of these seeds if a fire occurs
The hotter the fire, the more prickly moses you will see
What are some adaptation of the Hakea?
They are honey bearers, which feeds pygmy possums
They have a woody seedpod, which protects the seed in response to heat (fires)
What are some adaptation of the Snotty gobble?
Produces edible fruit that is full of vitamin C
They have thick bark for protection against heat
They have shallow roots, that have a fine network of roots that gather slight moisture in the dry, arid conditions
What are some adaptation of the yellow Buttercups?
Their underside is much lighter green with fine thin hairs compared to the top. Which helps it survive closer to the ground during hot summers, as light reflects up from the ground to the underside of the leaf, the lighter colour helps it to reflect back to the atmosphere.
As it closer to the ground it accumulates alot of leaf litter
What are some adaptation of the Wattle?
Browns off as it becomes metabolically inactive, until it rains it goes back to green
