Biome Awareness Disparity is BAD for tropical ecosystem conservation and restor...
Silveira, Fernando A. O.; Ordóñez-Parra, Carlos A.; Moura, Livia C.; Schmidt, Isabel B.; Andersen, Alan N.; Bond, William; Buisson, EliseMade available in DSpace on 2022-04-28T19:46:24Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01; We introduce the concept of Biome Awareness Disparity (BAD)—defined as a failure to appreciate the significance of all biomes in conservation and restoration policy—and quantify disparities in (a) attention and interest, (b) action and (c) knowledge among biomes in tropical restoration science, practice...
Climate mediates the effects of disturbance on ant assemblage structure
Gibb, Heloise; Sanders, Nathan J.; Dunn, Robert R.; Watson, Simon J.; Photakis, Manoli; Abril, Sílvia; Andersen, Alan N.; Angulo, Elena; Armbrecht, IngeMany studies have focused on the impacts of climate change on biological assemblages, yet little is known about howclimate interacts with other major anthropogenic influences on biodiversity, such as habitat disturbance. Using a unique global database of 1128 local ant assemblages, we examined whether climate mediates the effects of habitat disturbance on assemblage structure at a global scale. Species richness...
Multi‐scale ant diversity in savanna woodlands: an intercontinental comparison
Campos, Ricardo I.; Vasconcelos, Heraldo L.; Andersen, Alan N.; Frizzo, Tiago L. M.; Spena, Kelly C.Ecological patterns and processes are highly scale-dependent, but few studies have used standardized methodology to examine how scale dependency varies across continents. This paper examines scale dependency in comparative ant species richness and turnover in savannas of Australia and Brazil, which are well-matched climatically but whose ant faunas have contrasting biogeographic origins. The study was conducted...
Biodiversity consequences of land-use change and forest disturbance in the Amaz...
Solar, Ricardo Ribeiro de Castro; Barlow, Jos; Andersen, Alan N.; Schoereder, José H.; Berenguer, Erika; Ferreira, Joice N.; Gardner, Toby AlanQuantifying and understanding the main drivers of biodiversity responses to human disturbances at multiple scales is key to foster effective conservation plans and management systems. Here we report on a detailed regional assessment of the response of ant communities to land-use change and forest disturbance in the Brazilian Amazon. We aimed to explore the effects of land-use intensification at both site and la...
Fire in the Amazon: impact of experimental fuel addition on responses of ants a...
Paolucci, Lucas N.; Maia, Maria L. B.; Solar, Ricardo R. C.; Campos, Ricardo I.; Schoereder, José H.; Andersen, Alan N.The widespread clearing of tropical forests causes lower tree cover, drier microclimate, and higher and drier fuel loads of forest edges, increasing the risk of fire occurrence and its intensity. We used a manipulative field experiment to investigate the influence of fire and fuel loads on ant communities and their interactions with myrmecochorous seeds in the southern Amazon, a region currently undergoing extr...
Fire-induced forest transition to derived savannas: Cascading effects on ant co...
Paolucci, Lucas N.; Schoereder, José H.; Brando, Paulo M.; Andersen, Alan N.Changes in land-use and climate increase the flammability of forests across southeast Amazonia, potentially driving abrupt fire-mediated transitions to derived savannas – grass-dominated degraded forests with scattered trees. However, the extent to which the forest fauna undergoes a parallel process remains poorly understood. Here we test the hypothesis that the process of fire-driven forest shifts towards deri...
The database of the PREDICTS (Projecting Responses of Ecological Diversity In C...
Hudson, Lawrence N; Newbold, Tim; Contu, Sara; Hill, Samantha L L; Lysenko, Igor; De Palma, Adriana; Phillips, Helen R P; Alhusseini, Tamera IThe PREDICTS project-Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)-has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional statistical mod...
