Loss of Biodiversity
Causes of biodiversity loss: HIPPCO
• H: habitat destruction
• I: invasive species
• P: population growth
• P: pollution
• C: climate change
• O: over exploitation

Conservation BiologyConservation biology is the management of nature and of Earth's biodiversity
with the aim of protecting species, their habitats, and ecosystems from
excessive rates of extinction and the erosion of biotic interactions.
• Large, un-fragmented habitats• Better to preserve intact habitats than to focus on single
species at a time• in situ conservation (on site) – parks, preserves, areas of
high biodiversity (preservation and restoration)• ex situ conservation (off site) – captive breeding
programs, seed storage of diverse plant crops

Lab: Theory of Island Biogeography
![Page 7: Endangered Species “Missing Person” / “Have You …On Guadalupe Island, Mexico, there are thirty-four plants found nowhere else on Earth—almost all of them endangered because](https://reader030.fdocuments.in/reader030/viewer/2022040618/5f299fd89fda197b370d8bcd/html5/thumbnails/7.jpg)
Theory of Island Biogeography
Species richness in
isolated areas (islands)
affected by:
1. distance from
mainland
2. size of isolated area

Invasive Species
• lack normal predation control or other
limiting factors
• natural or human introduced
• degrading existing/normal habitats
• reducing biodiversity
• Either entering a currently-unfilled
niche
• Or…outcompeting an existing species
for its niche (niche overlap)
• adding new diseases
• not all non-native species become invasive
or are bad: ornamental, crops, farm
animals

Many island species have evolved to be specialists versus generalists because
of the limited resources, such as food and territory, on most islands. The
long-term survival of specialists may be jeopardized if and when invasive
species, typically generalists, are introduced and outcompete the specialists.

On Guadalupe Island, Mexico, there are thirty-four
plants found nowhere else on Earth—almost all of
them endangered because feral goats decimated the
landscape. The island was once covered with forest,
but by 1948, the forest was down to only 1% of its
former extent. Scientists put up fences to exclude
goats from certain areas, and the results were dramatic.
