Pervasive gaps in Amazonian ecological research

Carvalho, Raquel L.; Resende, Angelica F.; Barlow, Jos; França, Filipe M.; Moura, Mario R.; Maciel, Rafaella; Alves-Martins, Fernanda; Shutt, Jack

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain underst...


Dung removal increases under higher dung beetle functional diversity regardless...

Noriega, Jorge Ari; Hortal, Joaquín; deCastro-Arrazola, Indradatta; Alves-Martins, Fernanda; Ortega, Jean C. G.; Bini, Luis Mauricio; Andrew, Nigel R.

Dung removal by macrofauna such as dung beetles is an important process for nutrient cycling in pasturelands. Intensification of farming practices generally reduces species and functional diversity of terrestrial invertebrates, which may negatively affect ecosystem services. Here, we investigate the effects of cattle-grazing intensification on dung removal by dung beetles in field experiments replicated in 38 p...


Short- and long-term temporal changes in the assemblage structure of Amazonian ...

Noriega, Jorge Ari; Santos, Ana M. C.; Calatayud, Joaquín; Chozas, Sergio; Hortal, Joaquín

Species diversity varies in space and time. Temporal changes in the structure and dynamics of communities can occur at different scales. We investigated the temporal changes of dung beetle assemblages in the Amazonian region along seasons, years, and successional stages. We evaluated if assemblage structure changes between temporal scales and whether such changes affect the functional structure of communities. ...

Hudson, Lawrence N.; Newbold, Tim; Contu, Sara; Hill, Samantha L.L.; Lysenko, Igor; Palma, Adriana de; Phillips, Helen R.P.; Senior, Rebecca A.

Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species' threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodivers...

New genera records of split-eyed owlflies (Neuroptera: Myrmeleontidae: Ascalaph...

Ardila-Camacho, Adrian; Noriega, Jorge Ari; Acevedo-Ramos, Fernando

The genera Ameropterus Esben-Petersen, 1922 and Fillus Navás, 1919 are recorded from Colombia for the first time. New distributional records for two Cordulecerus Rambur, 1842 species are also presented. Ameropterus dissimilis (McLachlan, 1871) and Ameropterus scutellaris (Gerstaecker, 1894) are redescribed and illustrated, and Ameropterus mexicanus (Van der Weele, 1909) is here proposed as a junior synonym of t...

Hudson, Lawrence N; Newbold, Tim; Contu, Sara; Hill, Samantha L L; Lysenko, Igor; De Palma, Adriana; Phillips, Helen R P; Alhusseini, Tamera I

The 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...

Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species’ threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodivers...
