Brazil’s biodiversity is one of the richest in the world. It is estimated that the biodiversity in
Brazil represents around 20 percent of all life on the planet.
The State of Bahia
• 4th largest population • Size of 567,295 km² and tropical climate it is host to a plethora of floral and faunal species• Fragile Areas include the Atlantic Forrest
Bahia-Before the 1990’s
Cocoa economic boom of the 1970s and Development in Bahia had expanded into fragile ecosystems.The state had done little to take a more active role in land-use planning or protecting ecosystems
Environmental Problems
• Land degradation• Deforestation• Lost of species
All of these issues lead to the decline of Brazil’s endangered Atlantic Forest ecosystem, of which only about 10% persists today.
Bahia After 1990’s
• In the past decade the State of Bahia has aggressively implemented a policy of creating environmentally protected areas. The number of APAs and the area covered by them have grown significantly.
Pratigi • Created April 2, 1998• Localized region of Bahia South Bass• Five municipalities make up their territory: Ibirapitanga,
Igrapiúna, Ituberá Nile and Northern Pirai.• In the list of 34 global biodiversity hotspots, requiring us all
priority conservation actions, due to its high degree of biological diversity.

Replication study of "arboreal ant assemblages respond differently to food source and vegetation
types: a study in the Atlantic Rain Forrest" carried out five years ago
Concept behind the Project
As trophic groups of ants that are glucose and protein consumers are generalist and specialist, respectively, ant assemblages of generalist ants are expected to be more similar while the specialists would be different between habitats.As conservation increase and food sources diversify and increase overall species diversity of both generalists and specialists ants were expected to increase.
Using ants as bio indicators

Both
Deforested Areas are less diverse
Increase Diversity of Forest should result in an increase in food source

Sorting Samples We removed the glasses with alcohol and emptied the bags.

Comparison-The objective of this project is to make a direct comparison
5 years ago• 69 species of ants were
attracted to the bait.• 21 Honey unique, 25 unique
sardines• Agro Forestry the Reserved
forest had the highest species diversity
2013,2014• Data is still being Collected
but preliminary data Collection suggests that there has been an increase in the number species of ants.
If conservation efforts are successful, the number of ant species will increase until
a climax community is reached.

Investigate the different populations of ant species whose habitats are in three distinct regions of the area Pratigi.
Morphological Identification
• Dark reddish-brown to piceous with antennae and legs yellowish-brown reddish-brown
Leg
antennae
Morphological Identification• Petiole with conspicuous
transverse striae. conspicuous anteriorly, laterally, and baso-posteriorly, but reduced or lacking on remainder of posterior region; paired, slender, acute metasternal spines present.
• First gastral tergite shagreened and with fine appressed pubescence separated by at least one-fourth the length of each hair
• Head Length usually greater than 2.5 mm
• Pronotum with transverse striae posteriorly
Total Length
Petiole Pronotum
gaster
Genetic Analysis-CO1-gene "gene barcoding ideal"
• Present in most eukaryotic species.• Encodes a protein that is vital to cellular
respiratory function.• Found in the mitochondria so it is easy to
control because maternal lineages mitochondrial genes are received exclusively from the mother.
• Does not undergo recombination.
MethodExtraction, PCR, Gel Electrophoresis

Cultural Component
It is not only a scientific exchange program it is also a cultural exchange program
• Attempt to learn the language• Attempt to eat the food• Go sight seeing • Make friends
Advantages of SIFI
• Helps in understanding the social aspect of research
• Growth as a researcher in understanding global impacts of research
• Plan and execute research projects• Research experience that graduate schools are
interested in • Increase cultural understanding
Advice
• Do not be scared or intimidated• Ensure that this is the type of research you are
interested in• Build tolerance • Immerse yourself in the culture and Enjoy the
experience
