4Temperate Broadleaf Forests
- Region Temperate latitudes, especially
Europe, - East Asia, and Eastern U.S.
- Climate Seasonal, with harsh winters, mild or
hot summers - PPT 30-80 inches (75-200cm) per year
- Daylight Longer in summer
- Plant life Deciduous trees beech, maple, oak,
hickey, elms - Animals A range, all with adaptations to
survive winter

6Environmental Issues inTemperate Forests
- habitat loss
- acid rain
- ozone
- increased CO2, global warming
- fragmentation
- invasive species
7Characteristics of Invasive Species
8Profile of an Invasive Species
- High reproduction
- High dispersal
- High population growth rates
- r-selected (vs. K-selected)
- Competitive advantage (growth, predator
resistance, foraging) - Frequently thrives in disturbed habitats (which
are often more ecologically similar than
non-disturbed habitats). - Alters habitat to the detriment of native species
9Some Invasive Animals in U.S.
- Africanized honeybee (Apis mellifera scutellata)
- Asian long-horned beetle (Anoplophora
glabripennis) - Asian tiger mosquito (Aedes albopictus)
- Brown tree snake (Boiga irregularis)
- Cane toad (Bufo marinus)
- European gypsy moth (Lymantria dispar)
- European starling (Sturnus vulgaris)
- Red imported fire ant (Solenopsis invicta)
- Wild Boar (Sus scrofa)
10Some Invasive Wetland Species
- Asian swamp eel (Monopterus albus)
- Bullfrog (Rana catesbeiana)
- European green crab (Carcinus maenas)
- Northern Snakehead (Channa argus)
- Nutria (Myocastor coypus)
- Round goby (Neogobius melanostomus)
- Sea lamprey (Petromyzon marinus)
-
Zebra mussel (Dreissena polymorpha)

13RE The Black Walnut Problem Posted by
sbeuerlein zone 6 (My Page) on Wed, May 21, 03 at
913Shadowgarden, You bring up good points. The
natural variance of seedling trees, of which
nearly all Black Walnuts are, is considerable.
Also, it is certainly possible that the tolerance
to juglone can vary quite a bit within other
seedling species or varieties. For instance,
despite Azaleas being listed again and again as
having no resistance to juglone, my "Karen"
azaleas are thriving in the shadow of my walnut.
This is a complex issue, a very interesting
one, that hopefully will be studied more in the
future. Here in Ohio, I am more and more
convinced that the invasives Lonicera maackii and
Lonicera tatarica are allelopathic nightmares.
Very little seems to grow in their presence, and
I've seen virtually nothing in print to indicate
that this is recognized or studied by scientists.

14The Berry Fiends Final Lab Packet This topic
submitted by Kristi Brockman, Greg Evans, Lauren
Lynn, Jeff Martin, Corinne Mehas (
LYNNLT_at_muohio.edu ) on 12/11/98 .
The main problem being addressed in this
experimental procedure for the first part of the
lab is what affect differences in growing
conditions have on honeysuckle berry production
and ripeness.
15How Temperature and Day Length effect the rate
that honeysuckle bushes lose leaves This topic
submitted by Megen Leigh, Nicole Mihevic, Dan
Kehn, Erica Govich (Nickel365_at_aol.com) at 1242
pm on 12/11/01.
- To control day length black plastic bags were
used
- Plants were brought inside to provide a
different temperture
16Some other Student Lab Topics
- Wood density and growth of HS
- Plant architecture and shading
- Allelopathy of HS
- Predators
- Alternate uses of HS
