Collectively, reservoirs created by dams are thought to be an important source of greenhouse gases (GHGs) to the atmosphere. So far, efforts to quantify, model, and manage these emissions have been limited by data availability and inconsistencies in methodological approach. Here, we synthesize reservoir CH4, CO2, and N2O emission data with three main objectives: (1) to generate a global estimate of GHG emissions from reservoirs, (2) to identify the best predictors of these emissions, and...
Data from: Kooiichthys jono n. gen. n. sp., a primitive catfish (Teleostei, Siluriformes) from the marine Miocene of southern South AmericaMaria De Las Mercedes Azpelicueta, Alberto Luis Cione, Mario Alberto Cozzuol & Juan Marcos Mirande
A specimen of a remarkable new catfish genus and species was collected in middle/late Miocene marine beds of the Puerto Madryn Formation at the base of the marine cliff of the sea lion colony area near Puerto Pirámide, southern coast of Península Valdés, northeastern Patagonia, Argentina. Siluriforms (catfishes) constitute a most important monophyletic ostariophysan group of mainly freshwater fishes that occurs in almost all continents but it is especially diverse in South America. Catfishes are...
Data from: Biotic and abiotic variables influencing plant litter breakdown in streams: a global studyLuz Boyero, Richard Pearson, Cang Hui, Mark Gessner, Javier Perez, Markos Alexandrou, Manuel Graça, Bradley Cardinale, Ricardo Albariño, M. Arunachalam, Leon Barmuta, Andrew Boulton, Andreas Bruder, Marcos Callisto, Eric Chauvet, Russell Death, David Dudgeon, Andrea Encalada, Veronica Ferreira, Ricardo Figueroa, Alex Flecker, , Julie Helson, Tomoya Iwata, Tajang Jinggut … & Catherine Yule
Plant litter breakdown is a key ecological process in terrestrial and freshwater ecosystems. Streams and rivers, in particular, have high rates of carbon dioxide evasion and they contribute substantially to global carbon fluxes. However, there is little information available on the relative roles of different drivers of plant litter breakdown in fresh waters, particularly at large scales. We present a global-scale study of litter breakdown in streams to compare the roles of biotic, climatic and...
Data from: Climatic drivers of leaf traits and genetic divergence in the tree Annona crassiflora: a broad spatial survey in the Brazilian savannasPriciane C. Ribeiro, Matheus L. Souza, Larissa A. C. Muller, Vincenzo A. Ellis, Myriam Heuertz, José P. Lemos-Filho & Maria Bernadete Lovato
The Cerrado is the largest South American savanna and encompasses substantial species diversity and environmental variation. Nevertheless, little is known regarding the influence of the environment on population divergence of Cerrado species. Here, we searched for climatic drivers of genetic (nuclear microsatellites) and leaf trait divergence in Annona crassiflora, a widespread tree in the Cerrado. The sampling encompassed all phytogeographic provinces of the continuous area of the Cerrado and included 397 individuals belonging to 21...
Quantifying the spatio-temporal distribution of arthropods in tropical rainforests represents a first step towards scrutinizing the global distribution of biodiversity on Earth. To date most studies have focused on narrow taxonomic groups or lack a design that allows partitioning of the components of diversity. Here, we consider an exceptionally large dataset (113,952 individuals representing 5,858 species), obtained from the San Lorenzo forest in Panama, where the phylogenetic breadth of arthropod taxa was surveyed using 14...
Data from: Experimentally reducing species abundance indirectly affects food web structure and robustnessMilton Barbosa, G. Wilson Fernandes, Owen T. Lewis & Rebecca J. Morris
Studies on the robustness of ecological communities suggest that the loss or reduction in abundance of individual species can lead to secondary and cascading extinctions. However, most such studies have been simulation-based analyses of the effect of primary extinction on food web structure. In a field experiment we tested the direct and indirect effects of reducing the abundance of a common species, focusing on the diverse and self-contained assemblage of arthropods associated with an abundant...
Data from: Patterns of taxonomic and functional diversity of termites along a tropical elevational gradientCássio Alencar Nunes, André Vieira Quintino, Reginaldo Constantino, Daniel Negreiros, Ronaldo Reis-Júnior & G. Wilson Fernandes
Patterns of termite richness along elevation gradients may be related to different responses by termite functional groups to changes in environmental conditions. We investigated the distribution of termite species richness along an elevational gradient of cerrado and rupestrian grasslands in the Espinhaço Mountain Range, in Brazil. Fifty termite species were recorded, with the family Termitidae being dominant; 16 species are endemic to open areas of cerrado and 1 species, Cortaritermes rizzinii, is endemic and restricted...
