Brain expansion in early hominins predicts carnivore extinctions in East Africa
While the anthropogenic impact on ecosystems today is evident, it remains unclear if the detrimental effect of hominins on co‐occurring biodiversity is a recent phenomenon or has also been the pattern for earlier hominin species. We test this using the East African carnivore fossil record. We analyse the diversity of...Faurby, Søren ; Silvestro, Daniele ; Werdelin, Lars ; Antonelli, Alexandre

Drivers of bromeliad leaf and floral bract variation across a latitudinal gradient in the Atlantic Forest
Aim Understanding the complex interaction and relative contributions of factors involved in species and trait diversification is crucial to gain insights into the evolution of Neotropical biodiversity. Here, we investigated the drivers of morphological variation in bromeliads along a latitudinal gradient in a biodiversity hotspot. Location Atlantic Forest, Brazil. Taxon...Neves, Beatriz ; Zanella, Camila M. ; Kessous, Igor M. ; Uribbe, Fernando P. ; Salgueiro, Fabiano …

Why mountains matter for biodiversity
Mountains are arguably Earth's most striking features. They play a major role in determining global and regional climates, are the source of most rivers, act as cradles, barriers and bridges for species, and are crucial for the survival and sustainability of many human societies. The complexity of mountains is tightly...Perrigo, Allison ; Hoorn, Carina ; Antonelli, Alexandre

A novel phylogenetic infrageneric classification of Baccharis (Asteraceae: Astereae), a highly diversified American genus
We present the hitherto most comprehensive phylogenetic hypothesis for Baccharis. Our results confirm that subtribe Baccharidinae is a monogeneric group and support a broad circumscription of Baccharis as monophyletic with the inclusion of all genera that have been previously segregated from it (Baccharidastrum, Baccharidiopsis, Heterothalamulopsis, Heterothalamus, Lanugothamnus). We provide comprehensive...Heiden, Gustavo ; Antonelli, Alexandre ; Pirani, José Rubens

Species limits in butterflies (Lepidoptera: Nymphalidae): reconciling classical taxonomy with the multispecies coalescent
Species delimitation is at the core of biological sciences. During the last decade, molecular‐based approaches have advanced the field by providing additional sources of evidence to classical, morphology‐based taxonomy. However, taxonomy has not yet fully embraced molecular species delimitation beyond threshold‐based, single‐gene approaches, and taxonomic knowledge is not commonly integrated...Matos‐Maraví, Pável ; Wahlberg, Niklas ; Antonelli, Alexandre ; Penz, Carla M.

Unlocking the properties of plants and fungi for sustainable development
Humans have been using biodiversity for hundreds of thousands of years, but at no time in our history has it been more crucial to accelerate our exploration of the useful properties of the species that inhabit the world around us.Antonelli, Alexandre ; Smith, Rhian J. ; Simmonds, Monique S. J.

The effects of climate change on the distribution of South American antbirds (Thamnophilus punctatus complex) as affected by niche divergences and contact zone interactions between species
Several studies have shown that climatic change has been accelerating due to human activities, leading to dramatic effects on biodiversity. Modeling studies describe how species have reacted in the past to climatic change, and this information can help us to understand the degree of biotic susceptibility to current and future...da Silva, Erasmo Andrade ; de Araujo, Helder Farias Pereira ; Aleixo, Alexandre ; Antonelli, Alexandre ; Fernandes, Alexandre

The Impact of Mutualisms on Species Richness
Mutualisms – cooperative interactions among different species – are known to influence global biodiversity. Nevertheless, theoretical and empirical work has led to divergent hypotheses about how mutualisms modulate diversity. We ask here when and how mutualisms influence species richness. Our synthesis suggests that mutualisms can promote or restrict species richness...Chomicki, Guillaume ; Weber, Marjorie ; Antonelli, Alexandre ; Bascompte, Jordi ; Kiers, Toby
