Grazing impact and prey selectivity of picoplanktonic cells by mixotrophic flagellates in oligotrophic lakes
(Springer, 2019-03)
Mixotrophy by planktonic algae can dominate picoplankton predation in oligotrophic environments. We compared the grazing activity and prey preference of different mixotrophic taxa from natural communities of two oligotrophic ...
Invader to invader facilitation: ice plant mats prompt increased densities and grazing impacts of white garden snails in a Pampean coastal dune system
(Springer, 2021-04)
Non-native species can facilitate other non-native species via their effects on the physical environment. Here, I evaluate whether the ice plant, Carpobrotus edulis, prompts increased densities and grazing impacts of the ...
Is there competition between Haemonchus contortus and Haemonchus placei in a pasture grazed by only sheep?
(2020-03-01)
This study aimed to evaluate the dynamics of Haemonchus contortus and Haemonchus placei infections and hybridization between these species in grazing sheep without contact with cattle. On January 14, 2014, sixteen young ...
Grazing ecology and the conservation of the Caldenal rangelands, Argentina
(Elsevier, 2016-11)
Grazing by domestic livestock in the Caldenal rangelands has been threatening the ecological balance of this unique biome located in the semiarid zone of central Argentina. The aim of this review was to describe and explain ...
Aquatic plant composition and environmental relationships in grazed Northwest Patagonian wetlands, Argentina
(Elsevier Science Inc, 2014)
Aquatic macrophyte assemblages and environmental features were assessed in 30 wetlands from North- west Patagonia subjected to different intensity of grazing pressure. Species richness was surveyed in wetlands from three ...
Nitrogen soil budgets in contrasting dairy grazing systems of southern chile, a short-term study
(SOC CHILENA CIENCIA SUELO, 2010)
In recent years, the intensification of livestock production in Southern Chile has resulted in a high potential for environmental damage through nitrogen (N) losses, creating the need for the evaluation of N flows from ...
Plant interactions balance under biotic and abiotic stressors: The importance of herbivory in semi-arid ecosystems
(Springer, 2020-10)
Biotic and abiotic stressors commonly co-occur in plant communities and influence interactions between plants. However, their combined effects on plant interactions have not been widely studied and are still unclear. Here, ...
