Introduction
I have a broad interest in Ecology, Evolutionary Biology and Conservation Biology, but my main interest lies in understanding the interplay between ecological and evolutionary dynamics and its effects on biodiversity. I address these kind of questions by combining aspects of phylogenetics, complex network and functional ecology, using species traits as a biological building block to understand eco-evolutionary dynamics and their consequences to ecological communities and ecosystems services.

Article
Full-text available
Understanding how evolutionary and ecological processes shape species interaction networks remains as one of the main challenges in eco-evolutionary studies. Here, we present an integrative analytical framework to partition the effects of phylogenies and functional traits on the structure of ecological networks. The method combines fuzzy set theory...
Article
Full-text available
Understanding cascading effects of species loss is a major challenge for ecologists. Traditionally, the robustness of ecological networks has been evaluated based on simulation studies where primary extinctions occur at random or as a function of species specialization, ignoring other important biological factors. Here, we estimate the robustness o...
Article
Full-text available
Progress in phylogenetic community ecology is often limited by the availability of phylogenetic information and the lack of appropriate methods and solutions to deal with this problem. We estimate the effect of the lack of phylogenetic information on the relations among taxa measured by commonly used phylogenetic metrics in comparative studies and...
Article
Full-text available
Larger geographical areas contain more species—an observation raised to a law in ecology. Less explored is whether biodiversity changes are accompanied by a modification of interaction networks. We use data from 32 spatial interaction networks from different ecosystems to analyse how network structure changes with area. We find that basic community...
Article
Full-text available
The erosion of functional diversity may foster the collapse of ecological systems. Functional diversity is ultimately determined by the distribution of species traits. As species traits are a legacy of species evolutionary history, one might expect that the mode of trait evolution influences community resistance under the loss of functional diversi...

Aim Identify environmental and anthropogenic drivers of alpha‐ and beta‐diversity for native and alien plant species. Río de la Plata grasslands, South America (Argentina, Brazil and Uruguay; ‐27.3/‐39.1 latitude, ‐50.1/‐66.5 longitude). Methods We assembled a dataset of 597 vegetation plots distributed across the Río de la Plata grasslands. To a...
Article
Trait-based approaches offer complementary views to the classic taxonomic approach, which is a crucial step forward to unveil mechanisms of community assembly, species interactions, ecosystem functioning, and tackling important conservation issues. These approaches require an enormous sampling effort to provide complete trait datasets, consequently...

Aim The aim was to evaluate the effects of climate warming on biodiversity across spatial scales (i.e., α‐, β‐ and γ‐diversity) and the effects of patch openness and experimental context on diversity responses. Location Global. Time period 1995–2017. Major taxa studied Fungi, invertebrates, phytoplankton, plants, seaweed, soil microbes and zoopl...
Article
Full-text available
Biodiversity loss is currently one of the most important societal concerns worldwide, and it is caused mainly by habitat loss and fragmentation, biological invasion, and climate change (Vitousek et al. 1996, Newbold et al. 2015, Bellard et al. 2016). Introduced species can have positive effects on human well‐being, especially when used for liveliho...
Article
Full-text available
Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropica...

Aim The aim of this study was to evaluate how the area of habitat islands influences multiple facets of diversity. Location Southern Brazil. Taxon Birds. Methods Using an Information Theoretic approach, we compared the fit of 20 diversity–area relationship (DARs) models in three habitat island systems. We tested for the best‐fit model, model‐fam...
Article
Full-text available
1.Species are entangled within communities by their interactions in such a manner that their local extinction may unchain coextinction cascades and impact community dynamics and stability. Despite increasing attention, simulation models to estimate the robustness of interaction networks largely neglect the important role of interaction rewiring, i....

Understanding the consequences of habitat fragmentation to biological populations is crucial to develop sound conservation polices. The Straight-billed Reedhaunter (Limnoctites rectirostris) is a little known and threatened Passeriform that is highly dependent Erygo wetlands patches. Here, we evaluated the effects of habitat fragmentation on popula...
Article
Understanding road-kill patterns is the first step to assess the potential effects of road mortality on wildlife populations, as well as to define the need for mitigation and support its planning. Reptiles are one of the vertebrate groups most affected by roads through vehicle collisions, both because they are intentionally killed by drivers, and d...

Article
Full-text available
Managing ecological disturbances at different spatial scales is paramount for maintaining or restoring faunal diversity in grasslands. Whereas some studies have reported varying net effects of livestock disturbance intensity upon species richness in grasslands, most analysis reveal strong effects on beta-diversity. However, beta-diversity can be fu...
Article
Full-text available
Understanding the processes that drive patterns of beta diversity is crucial for planning conservation policies and for designing networks of protected area (PAs). Beta diversity can be decomposed into two components: 1—species turnover, the replacement of species by others resulting in a low proportion of shared species; 2—species nestedness—the r...

Sampling the full diversity of interactions in an ecological community is a highly intensive effort. Recent studies have demonstrated that many network metrics are sensitive to both sampling effort and network size. Here, we develop a statistical framework, based on bootstrap resampling, that aims to assess sampling sufficiency for some of the most...

Full-text available
We evaluated the effects of climate seasonality from a thermal and water availability perspective on the activity patterns and resource use of Pecari tajacu and Tayassu pecari during wet and dry seasons in the northeastern Brazilian Pantanal. We used camera traps and temperature sensors to record species activity patterns in relation to temperature...
Article
Full-text available
Background: Inselbergs are known to influence vegetation patterns worldwide. In extra-tropical areas, opposing slopes of inselbergs have different exposures to solar radiation; for example, in southern South America, north-facing slopes are more exposed to solar radiation than south-facing slopes, both in terms of angle and period of incidence. Aim...
Thesis
Full-text available
Understanding how species interact and how the topology of ecological networks influences the dynamics of populations and communities has been mind- boggling ecologists for over a century now. Despite this long tradition, the study of complex ecological networks has increased dramatically in the past two decades. Nonetheless, only recently ecologis...
Article
Full-text available
Species are different, but they are not equally different. Yet many indices of biodiversity assume species vary to identical degrees. This notion does not meet with intuition: some species vary greatly in terms of their morphology, behaviour and ecology, while others vary only a little. One way to reconcile the dissimilarity between species is by c...
Article
Full-text available
Nearly all remnants of temperate grasslands in southeastern South America are used for livestock ranching and are subject to habitat degradation resulting from this activity. Exploring how habitat features affect the composition of grassland avifaunal communities is a first step to understand how current cattle-ranching management practices impact...
Article
Disentangling the effects of climate and historical factors on biodiversity distribution remains a challenge for biogeographers. Here, we provide an analytical framework to discriminate the contributions of contemporary climate and the biogeographical history of taxa to the geographical distributions of phylogenetic lineages. Furthermore, we evalua...
Article
Full-text available
Beta diversity is defined as the variation in species composition among sites within a region of interest. This variation can be explained by different metacommunity paradigms, which are not mutually exclusive. While species sorting emphasizes the role of habitat features in affecting species composition, the neutral model suggests that constraints...
