Mexico's Forests Flashcards
How does ecotourism play a key role in forest conservation in Mexico?
Addresses the problems of rural poverty and deforestation by generating revenue similar to logging. The influx of visitors to remote areas incentivizes locals to preserve their natural resources. It can also improve gender equity, preserve local culture, and protect wildlife.
Who owns the majority of the Sierra Gorda Biosphere Reserve?
Ejidos (indigenous groups) and private landowners
What has Sierra Gordon Ecotours done in the biosphere reserve in regards to ecotourism?
Started 15 ecolodges and 53 artisan and resturant buisnesses that are owned and operated by locals, many of which are women
What percentage of native fish in Arizona are listed as threatened or endangered?
56%
Where is over 90% of the heat trapped by the human driven rise in atmospheric greenhouse gas concentration taken up at?
Oceans
When will monsoon season in the Southwest fall if climate change keeps continuing?
Later summer and fall, leaving the hottest season very dry
Will flood events increase or decrease if climate change trends continue?
Increase
What is going to happen to rivers in the Southwest because of climate change?
They will become increasingly dominated by temperature-driven reductions in flows, despite periods of above-normal snowpack that occasionally compensate for temperature-driven reductions.
What kind of flow reductions could the colorado river see during megadroughts if climate change continues?
50-75%
What kind of areas are the health and survivability of aquatic habitats dependent on?
Riparian and upland terrestrial vegetation
What percentage of arizona’s area is riparian?
0.4%
How much of Arizona’s vertebrate species spend some portion of their life cycle in riparian zone?
80%
How do higher temperatures affect fish biologically?
Affect their neuroendocrine processes, metabolic processes, immune defenses against parasites and pathogens, and various stages of reproduction.
What are some examples of fishes that are tolerant to high temperatures?
The Cottonball Marsh pup-fish, Gila topminnow, and other pupfishes
What Arizona desert fish have intermediate heat tolerances?
Roundtail chub, pikedace, desert sucker, loach minnow, and razorback sucker
What arid-land salmonids are sensitive to high temperatures?
Apache trout, Rio Grande cutthroat trout, and Gila trout
How would decreased streamflow because of climate change affect fishes?
Shrink available habitat, fragement habitats, and affect water quality
How does wildfire affect fish?
Suspended sediment in streamflows can kill fish
How does lowering water levels affect the ionic balance of fishes?
It increases the concentrations of salt in the water
What is tourism?
The activities of people traveling to and staying in places outside their usual environment for no more than one consecutive year for leisure, business, or other purposes
How many people crossed international borders last year?
