On traits matching and the modular organization of food web and occurrence networks

Journal of Animal Ecology, EarlyView.
What mechanisms shape ecological networks? In Paraná River piscivores, species traits and abundance scaling promote modular structures. Our findings reveal how communities self‐organize and highlight the conditions needed to sustain them. Abstract Modularity and nestedness have been observed recurrently across different ecological networks, including ...

Bird-plant interaction networks: a study on frugivory in Brazilian urban areas

Biotemas, 2015
In Brazil, few studies compare the consumption of native and exotic fruits, especially in an urban environment. The Network Theory may be useful in such studies, because it allows evaluating many bird and plant species involved in interactions. The goals

Ecology and co-existence of two endemic day gecko (Phelsuma) species in Seychelles native palm forest [PDF]

, 2011
In island ecosystems, reptiles play diverse ecological roles as a result of niche broadening, which increases potential niche overlap between species. Ecological niche partitioning is a means of reducing direct competition between coexisting species and ...

Bat Tongues and Foraging: Linking Morphology to Hunting Strategies

Integrative Zoology, EarlyView.
We linked the bat tongue's mediodorsal lobe (MDL), a muscular prominence, to foraging strategies. Aerial hawkers exhibit tall MDLs and prominent forward‐pointing papillae. The MDL may function as a barrier or filter, preventing unintentional ingestion of non‐food material, aiding in prey handling, and controlling food access during fast flight ...

Birds consuming fruits of Varronia curassavica Jacq. (Boraginaceae) in southastern Brazil (Scientific Note). Aves consumidoras dos frutos de Varronia curassavica Jacq. (Boraginaceae) no Sudeste do Brasil (Nota Científica) [PDF]

Revista do Instituto Florestal, 2017
The Tropical Black Sage Varronia curassavica Jacq. is a widespread shrub in Brazil, which has become invasive in some parts of the world. We recorded 24 bird species consuming its fruits and potentially dispersing its seeds at Alberto Löfgren State ...

Frugivory and seed dispersal by chelonians: A review and synthesis [PDF]

Biological Reviews, 2018
AbstractIn recent years, it has become clear that frugivory and seed dispersal (FSD) by turtles and tortoises is much more common than previously thought. Yet, a review and synthesis is lacking. We here review published and unpublished records of chelonian FSD, and assess the role of chelonians as seed dispersers, from individual species to the ...

Evolutionary correlates and consequences of sociality in feliform carnivorans

Journal of Zoology, EarlyView.
We take a phylogenetic comparative approach to investigate the evolutionary correlates of sociality in feliform (cat‐like) carnivores. We find that sociality evolved eight times in this group of mammals, and that it is associated with ecologies that facilitate group cohesion (e.g. diurnality and open habitats) and also that should reduce competition (e.

Individual variability shapes interaction rewiring and fosters ecosystem restoration by reintroduced giant tortoises in the Seychelles

Restoration Ecology, EarlyView.
Abstract Introduction Giant tortoises are critical for restoring lost ecological interactions on islands. Following their extinction in Seychelles centuries ago, key ecosystem processes like seed dispersal, browsing, and nutrient cycling were disrupted.

Seed rain generated by bats under Cerrado’s pasture remnant trees in a Neotropical savanna

Brazilian Journal of Biology
In this study we described the seed rain generated by bats under four Cerrado’s tree species common within pastures, Buchenavia tomentosa, Couepia grandiflora, Licania humilis and Qualea grandiflora. We analyzed the similarity among the four tree species

Seed dispersal by macaws shapes the landscape of an Amazonian ecosystem [PDF]

, 2017
Seed dispersal is one of the most studied plant–animal mutualisms. It has been proposed that the dispersal of many large-seeded plants from Neotropical forests was primarily conducted by extinct megafauna, and currently by livestock.
