ABSTRACT. - Land use changes are occurring with unprecedented magnitude and intensity, imposing global impacts on ecosystem services (ES) and biodiversity. While the impacts of land use changes are increasingly recognized, understanding how landscape connectivity is related to ecosystem functioning is lacking. In the Argentinian Dry Chaco, deforestation increased forest fragmentation but strips of native forest (linear remnants) were usually left after clearings. Although the number of ecological studies on forest strips has increased, their contribution to forest connectivity and functioning has not been assessed. We evaluated the contribution of forest strips to forest connectivity and estimated its effect on forests' functioning considering low, moderate, and high species' dispersal abilities in our estimation. The effects of forest strip connectivity contribution to the forests' Ecosystem Services Supply Index (Forests' ESSI) was also analyzed. Forest strips contributed on average 6% and up to 40% to forest connectivity for moderate dispersal abilities, while low and high dispersals presented low values in almost all cases. The connectivity contribution was highest (between 15 and 40%) and variable for moderate dispersal abilities in landscapes with between 25 and 35% of forest cover. High connectivity contribution was generally achieved for low and moderate dispersals when forest strips conformed a network among forest patches. Forest strip connectivity significantly increased the forests? ESSI (between 1.3 and 2.4% per unit of connectivity contribution) and its effect was higher in comparison to forest amount and fragmentation. This study provides insights for planning the location of forest strips and forest remnants in agricultural landscapes, thus increasing forest connectivity for enhancing ecosystem functioning.

Abstract:Amorimia spp. are sodium monofluoroacetate (MFA) containing plants causing sudden death in ruminants. In a previous study, Amorimia rigida caused abortion in one of the five pregnant sheep that received the plant suggesting that it may cause reproductive losses. This work aimed to study the embryotoxic and fetotoxic effects of Amorimia septentrionalis in goats in the Brazilian northeastern semi-arid region. The effects of A. septentrionalis on pregnancy were studied in 16 goats, divided into four groups according to their gestational period. In Groups 1, 2 and 3 the administration of A. septentrionalis at the daily dose of 5g of leaves per kg body weight was started on the 18th, 36th and 93th days of gestation, respectively. Goats from Group 4 did not ingest the plant. When the goats presented severe signs of poisoning the administration of the plant was suspended. Groups 1, 2 and 3 ingested the plant for 7.25±2.87, 9.25±2.21 and 12.50±0.57 days, respectively. All the goats recovered 7-12 days after the end of the administration of the plant. In Group 1, all the goats had embryonic death 6.25±3.59 days after the end of the ingestion of the plant. In Group 2, three goats aborted at 53, 54 and 78 days of gestation. Two goats from Group 3 gave birth normally and the other two aborted at 114 and 111 days of gestation. It is concluded that Amorimia septentrionalis is a sodium monofluoracetate-containing plant that causes embryonic deaths and abortions in goats that ingest non-lethal doses of the plant.

Este trabalho teve como objetivo estudar os efeitos embriotóxicos e fetotóxicos de Amorimia septentrionalis em caprinos na região semi-árida nordestina brasileira. Os efeitos de A. septentrionalis na prenhez foram estudados em 16 cabras, divididos em quatro grupos de acordo com seu período gestacional. Nos grupos 1, 2 e 3 a administração de A. septentrionalis foi diária, na dose de 5g de folhas por kg de peso corporal, iniciada nos dias 18, 36 e 93 da gestação, respectivamente. As cabras do grupo 4 não ingeriram a planta. Quando as cabras apresentavam sinais severos de intoxicação suspendia-se a administração da planta.

No grupo 1, todas as cabras apresentaram quadros de mortalidade embrionária 6,25±3,59 dias após o término da ingestão da planta. No grupo 2, três cabras abortaram aos 53, 54 e 78 dias de gestação.
