1. Agricultural intensification is one of the main drivers of species loss worldwide, but there is still a lack of information about its effect on functional diversity of arable weeds communities. 2. Using a large scale pan European study including 786 fields within 261 farms from eight countries, we analysed differences in the taxonomic and functional diversity of arable weeds assemblages across different levels of agricultural intensification in. We estimated weed species frequency in each...

The evolutionary history of sedges (Cyperaceae) in Madagascar

Isabel Larridon, Daniel Spalink, Pedro Jiménez-Mejías, José Ignacio Márquez-Corro, Santiago Martín-Bravo & Marcial Escudero
Aim: Madagascar is renowned for its unparalleled biodiversity and endemism. With many ecosystems under threat, research is urgently needed on its unique plant diversity. This applies both to Madagascar’s forests and treeless vegetation types. Sedges (Cyperaceae) are among the top ten species-richest angiosperm families in Madagascar (310 native species, 38% endemic), of which two thirds occur in open habitats. We aimed to infer the evolutionary history of sedges in Madagascar, by estimating the number, age...

Treefrogs adjust their acoustic signals in response to harmonics structure of intruder calls

Lucas Forti & Diego Llusia
Spectral properties of animal acoustic signals may help individuals to assess the characteristics of rivals and to adjust their competitive strategies in territorial disputes. Thus, we hypothesize that the distribution of energy across frequency bands in anuran calls determine behavioral responses in male-male competition. Using playback experiments, we investigated the relevance of the harmonic calls in the acoustic communication of the treefrog Dendropsophus minutus. We exposed territorial males to three synthetic acoustic stimuli composed of...

Radicalisation Influence in Social Media

Miriam Fernandez, Antonio Gonzalez-Pardo & Harith Alani
In an increasingly digital world, identifying signs of online extremism sits at the top of the priority list for counter-extremist agencies. Researchers and governments are investing in the creation of advanced information technologies to identify and counter extremism through intelligent large-scale analysis of online data. However, to the best of our knowledge, these technologies are neither based on, nor do they take advantage of, the existing theories and studies of radicalisation. In this paper we...

Data from: Drivers of assemblage-wide calling activity in tropical anurans and the role of temporal resolution

Larissa Sayuri Sugai, Thiago Silva, Diego Llusia & Tadeu Siqueira
1. Temporal scale in animal communities is often associated with seasonality, despite the large variation in species activity during a diel cycle. A gap thus remains in understanding the dynamics of short-term activity in animal communities. 2. Here we assessed calling activity of tropical anurans and addressed how species composition varied during night activity in assemblages along gradients of local and landscape environmental heterogeneity. 3. We investigated 39 anuran assemblages in the Pantanal wetlands (Brazil)...

Scale-dependent drivers of the phylogenetic structure and similarity of tree communities in northwestern Amazonia

Sebastián González-Caro, Joost Duivenvoorden, Henrik Balslev, Jaime Cavelier, Carlos Grández, Manuel Macia, Hugo Romero-Saltos, Mauricio Sanchez, Renato Valencia & Alvaro Duque
1. The extent to which historical dispersal, environmental features and geographic barriers shape the phylogenetic structure and turnover of tree communities in northwestern Amazonia at multiple spatial scales remains poorly understood. 2. We used 85 floristically standardized 0.1-ha plots (DBH ³ 2.5 cm) distributed in three subregions of northwestern (NW) Amazonia across three main habitat types (floodplain, swamp, terra firme forests), to hypothesize that: i) historical dispersal overcome geographical barriers, which meant low local phylogenetic...

A new remarkable dwarf sedge (Carex phylloscirpoid, Cyperaceae) from Northern Chile, with insights on the evolution of Austral section Racemosae

Pedro Jiménez-Mejías, Patricio Saldivia, Sebastian Gebauer & Santiago Martín-Bravo
We describe a new remarkable dwarf and apparently acaulescent species of Carex (Cyperaceae) from the Andes of northern Chile: Carex phylloscirpoides. Morphological and molecular data (two nuclear and three plastid DNA regions) were used to study the phylogenetic placement and systematic relationships of this species, which resulted in its assignment to section Racemosae. However, despite being related to the other three species of the section present in the Southern Cone based on phylogenetic evidence, it...

Rapid colour shift by reproductive character displacement in Cupido butterflies

Joan Carles Hinojosa, Darina Koubínová, Vlad Dincă, Juan Hernández-Roldán, Miguel L. Munguira, Enrique García-Barros, Marta Vila, Nadir Alvarez, Marko Mutanen & Roger Vila
Reproductive character displacement occurs when competition for successful breeding imposes a divergent selection on the interacting species, causing a divergence of reproductive traits. Here, we show that a disputed butterfly taxon is actually a case of male wing colour shift, apparently produced by reproductive character displacement. Using double digest restriction-site associated DNA sequencing and mitochondrial DNA sequencing we studied four butterfly taxa of the subgenus Cupido (Lepidoptera: Lycaenidae): Cupido minimus and the taxon carswelli, both...

Data from: Current climate, but also long-term climate changes and human impacts, determine the geographic distribution of European mammal diversity

Ana Margarida Coelho Dos Santos, Marcus Cianciaruso, A. Marcia Barbosa, Luis Mauricio Bini, José Alexandre Diniz-Filho, Frederico Augusto Faleiro, Sidney Gouveia, Rafael Loyola, Nagore Medina, Thiago Rangel, Geiziane Tessarolo & Joaquín Hortal
Aim. Historical climate variations, current climate and human impacts are known to influence current species richness, but their effects on phylogenetic and trait diversity have been seldom studied. We investigated the relationship of these three factors with the independent variations of species, phylogenetic and trait diversity of European mammals. Considering the position of the 0ºC isotherm in the Last Glacial Maximum as a tipping point, we tested the following hypotheses: northern European assemblages host less...

Trait data of European and Maghreb butterflies

Joseph Middleton Welling, Leonardo Dapporto Dapporto, Enrique García-Barros, Martin Wiemers, Piotr Nowicki, Elisa Plazio, Simona Bonelli, Michele Zaccagno, Martina Šašić, Jana Lipárová, Oliver Schweiger, Alexander Harpke, Martin Musche, Josef Settele, Reto Schmucki & Tim Shreeve
Trait-based analyses explaining the different responses of species and communities to environmental changes are increasing in frequency. European butterflies are an indicator group that responds rapidly to environmental changes with extensive citizen science contributions to documenting changes of abundance and distribution. Species traits have been used to explain long- and short-term responses to climate, land-use and vegetation changes. Studies are often characterised by limited traits sets being used, with risks that the relative roles of...
