Term
3 major features of Wetlands
Definition
Hydrology
Hydrophytic Plants
Hydric Soils
Term
Section 404 Clean Water Act
Definition
Army Corps of Engineers
Dredge and Fill Permits
"Navigable Waterways"
Term
Swampbuster Provision
Definition
US Dept of Agriculture
Farmers who negatively effect wetlands lose all USDA subsidies
Term
Hydroperiod
Definition
Time frame when wetland is flooded
Term
Hydrograph
Definition
Shows water level over time
Term
Flowthrough
Definition
water carries in nutrients
Increases Primary Productivity
Decreases organic matter accumulation
Term
Hydric Soils
Definition
Anaerobic Conditions
High in organic matter
Lack oxidized iron (gleying), have Oxidized rhizospheres, are Mottled
High export of carbon
Term
Muck
Definition
Hydric soil made up of mostly decomposed organic matter
Term
Peat
Definition
Hydric soil made up of mostly non-decomposed organic matter
Term
Mottled soil
Definition
iron oxides built up on soil surface
Term
Hydrophytic plants
Definition
have arenchyma
C4 Photosynthesis
rapid stem elongation
Oxygenated rhizosphere
buoyant seeds produced in dry season
Term
Arenchyma
Definition
Air spaces in roots and stems allowing diffusion of O2 into roots in anaerobic soils
Term
C4 Photosynthesis
Definition
Can photosynthesize with stomates closed
Prevents loss of nutrients to water
Term
Testudines
Definition
Order -Turtles
Term
Squamata
Definition
Order -Snakes and Lizards
Term
Anura
Definition
Order- Frogs and Toads
Term
Caudata
Definition
Order -Salamanders
Term
VT Turtles
Definition
All wetland dependent
eggs laid terrestrially
Newborns emerge in fall and head to nearest wetland
sex determined by temperature
Term
VT Wetland Snakes
Definition
All viviparous
eggs laid terrestrially]
Term
Viviparous vs Oviparous
Definition
Live Birth vs Egg Laying
Term
VT Frogs and Toads
Definition
eggs laid in water, external fertilization
Tadpole larval stage 6 weeks to 3 years
Dorsolateral fold and Lympanum
Term
Bufonidae
Definition
Toads
Toxic Warts
Breed in vernal pools or small wetlands
American and Fowlers Toads
Term
Hylidae
Definition
Tree Frogs
Spring Peeper, Gray Treefrog, Boreal Chorus Frog
Term
Ranidae
Definition
True Frogs
Tympanum vs. eye to distinguish sex
Bullfrog, Green Frog, Leopard Frog, Pickerel Frog, Mink Frog, Wood Frog
Term
VT Salamanders
Definition
Internal Fertilization
larvae have gills and 4 legs
Term
Mud Puppies
Definition
Proteidae
Large
Neotenic retention of gills
Term
Neotenic
Definition
Retains larval characteristics
Term
Mole Salamanders
Definition
Ambystomidae
Vernal Pool Specialists
Adults terrestrial except when breeding
Term
Newts
Definition
Salamandridae
Rough Skin w/poison glands
no costal grooves
terrestrial eft stage between larvae and adult stages
Term
Lungless salamanders
Definition
Plethodontidae
aquatic larvae, terrestrial adults
respire through moist skin and mouth
Term
wetland buffer pattern
Definition
Semlitsch and Bodie 2003
core wetland
aquatic buffer
Core habitat- includes aquatic buffer
50m terrestrial buffer
Term
Temporary wetland importance
Definition
Herp breeding grounds w/ no fish
Term
terrestrial buffer
Definition
"breathing room" for species that may leave core habitat
Term
release of captive herps
Definition
pets can become invasive species
Term
Development issues
Definition
chemical runoff from hard surfaces
Habitat loss
herps may lay eggs on asphalt that used to be breeding grounds
Term
Road issues
Definition
Herps run over en masse
May try to nest or bask on warm elevated asphalt
Term
Preventing road mortality
Definition
Drift fences and culverts
Term
road culverts
Definition
allow herps to pass under roads
Term
drift fences
Definition
prevent herps from crossing roads and lead them to culverts
Term
core habitat
Definition
area where most herp species live as adults
Term
Langen et al 2007
Definition
Herp life history leads to mass road crossing and therefore mass mortality at certain times of year
Term
Langen et al 2009
Definition
walking surveys take better measurements
landscape factors can determine crossing hotspots
