Abstract Anthropogenic disturbance and climate change are the main drivers of biodiversity loss ecological services around globe. There is concern that will exacerbate impacts thereby promote biotic homogenization, but its consequences for unknown. We investigated individual interactive effects increasing chronic anthropogenic ( CAD ) aridity on seed dispersal provided by ants in Caatinga vegetation north‐eastern Brazil. The study was conducted Catimbau National Park, Pernambuco, Within an...
Stomatal conductance (g s), transpiration (E), relative water content (RWC), superoxide dismutase activity (SOD), malondialdehyde (MDA), leaf carbohydrate soluble (LCS), free amino acids (FAA) and total protein (TP) were measured under mild severe drought stress in young potted Jatropha curcas L. the greenhouse. The plants kept for 12 days three different regimes, control (well hydrated), 50% irrigation (mild stress) 25% (severe stress), after rehydration on second fourth day. Both decreased...
Predicting community responses to disturbance is a major challenge for both ecology and ecosystem management. A particularly challenging issue that the same type intensity of can have different impacts in habitats. We investigate how habitat contingency influences ant arid Australia, testing hypothesis has greater impact more complex also assess effectiveness highly simplified assessment protocol considers larger species only. sampled ants at 46 sites from two habitats (Chandler, low...
The objective of this work was to determine the effect climatic seasonality on physic nut (Jatropha curcas), in field, under semiarid climate conditions. Stomatal conductance (g s), transpiration (E), soluble leaf carbohydrates (SLC), free amino acids (FAA) and total proteins (TP) were measured leaves, a commercial plantation Northeast Brazil, during summer autumn. Plants showed high g s E, as well SLC, FAA TP contents summer, which gradually decreased with lower temperatures...
Abstract Introduction Evolutionary traits acquired in response to one type of disturbance will potentially confer resilience other disturbances that have similar environmental impacts, even if the biota has no evolutionary history such disturbances. In grassy ecosystems impacts grazing important similarities those fire through removal grass biomass, and we hypothesise high frequent confers grazing. Aims We test this hypothesis by investigating highly fire-resilient ant communities a mesic...
