Area of interest

2

- Adaptive processes of wildlife to anthropogenic

environments (in special agricultural landscapes)

Rationale

3

- Agriculture: intrinsic conflict between the

production of domesticated species and the

conservation of wild species

- Impacts of agriculture on the wildlife:

- Direct land and use change (dLUC): Habitat loss

- Agriculture intensification: Context-specific

(dependent on agricultural management

techniques)

Wildlife in agricultural landscapes in

São Paulo, SE Brazil

- Medium to large mammals: 27 spp. (~ 70%)

- Small mammals: 17 spp. (~ 50%)

- Birds: 202 spp. (~ 60%)

- Reptiles: 18 spp.

- Amphibians: 31 spp.

- Fish: 55 spp.

From pastures to Eucalyptus

- Original biome: Cerrado

- ↓ Birds; ↑ Rodents; ↑ Amphibians; ↑ Reptiles

- ↑ Rodents → ↑ Mesopredators;

- ↑ Rodents → ↑ Diseases (e.g., Hantavirus,

Leptospirosis, Spotted fever etc);

- ↑ Rodents → ↑ Agrochemicals;

- ↑ Agrochemicals → ↓↓ Birds;

Wildlife mangement (at the population

level): What it is about...

• ↑ depleted populations: Biological conservation

• ↓ excessive populations: Control

• MSY: Sustainable use

• N.B.K.E.O.I: Monitoring

12

Graeme Caughley (1937-1994)

Wildlife mangement: what really

matters...

• Biological conservation: Endangered spp. (a few thousands)

• Sustainable use: Economic spp. (a few hundreds)

• Control: Damaging spp. (a few tens)

• Monitoring: All the others (a few millions...)

Diversity of patterns

- Momentary structure of a ‘community’

- Express the effects of ecological and

evolutionary processes

- No biological relationships

- Temporal variation does not mean much

for the decision making process
