Assessing how much management of agricultural landscapes, in addition to protected areas, can offset biodiversity erosion in the tropics is a central issue for conservation that still requires cross-taxonomic and landscape-scale studies. We measured the effects of Amazonia deforestation and subsequent land-use intensification in 6 agricultural areas (landscape scale), where we sampled plants and 4 animal groups (birds, earthworms, fruit flies, and moths). We assessed land-use intensification with a synthetic index based on landscape metrics (total area and relative percentages of land uses, edge density, mean patch density and diversity, and fractal structures at 5 dates from 1990 to 2007). Species richness decreased consistently as agricultural intensification increased despite slight differences in the responses of sampled groups. Globally, in moderately deforested landscapes species richness was relatively stable, and there was a clear threshold in biodiversity loss midway along the intensification gradient, mainly linked to a drop in forest cover and quality. Our results suggest anthropogenic landscapes with high-quality forest covering >40 % of the surface area may prevent biodiversity loss in Amazonia. |

Abstract: To identify the risk factors for toxoplasmosis in the microregions of the Brazilian State of Piauí, 1964 serum samples from 130 goat and sheep herds were tested using ELISA. Of these, 40.5% (235/580) of goats and 48.7% (182/374) of sheep from the upper-middle Gurguéia microregion (UMGM) had antibodies to Toxoplasma gondii. In the Teresina homogeneous microregion (THM), 49.4% (376/761) of goats and 67.5% (168/249) of sheep were seropositive. We observed that seropositivity in sheep from the UMGM was related to the extensive rearing system. For goats from the UMGM, risk factors included cats feeding on placenta remains, the number of domestic dogs on the farm and gender (female). The risk factors for toxoplasmosis in sheep from the THM included having more than two cats on the farm and domestic and wild dogs having access to herd drinking water. For goats from the THM, risk factors included being bred for meat and gender (female). Therefore, T. gondii is present in goat and sheep herds, suggesting that methods to prevent toxoplasmosis in the UMGM and THM of Piauí, Brazil are necessary. Goats and sheep raised in the State of Piauí, Brazil, have antibodies to T. gondii. Toxoplasmosis in sheep from the UMG microregion is related to extensive rearing Toxoplasmosis in goats from UMG microregion is related to cats eating placenta. Toxoplasmosis in sheep from TH microregion is related to the number of cats. Toxoplasmosis in goats from the TH microregion is related to meat production.
