Frequency of arboreality is correlated with longer hand skeletons in Gorilla: Analysis of a new skeletal sample of Bwindi mountain gorillas

Journal of Anatomy, EarlyView.
Variation in arboreality across gorilla populations is associated with systematic differences in manual digital lengths. Using a new dataset of linear metrics from the Bwindi mountain gorillas, we quantify metacarpal and phalangeal lengths in eastern and western gorilla populations across all five rays. Consistent with quantified behavioral differences,

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

Allometric patterns in Rhamphorhynchus muensteri and their role in the paleoecology, life habits, and taxonomic framework of pterosaurs

Journal of Anatomy, EarlyView.
The Graphical Abstract ilustrates the different allometric pattern within different Pterosauria groups, highlighting how the allometry influences the flight and habits of Pterosauria. Abstract Pterosaurs were the first vertebrates to achieve powered flight, a result of various unique anatomical adaptations, and significant morphological diversity ...

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 We here review published and unpublished records of chelonian FSD, and assess the role of chelonians as seed dispersers, from individual species to the ...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.

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.

Diet composition of the Red‐billed curassow (Crax blumenbachii) and its role as seed disperser in the Atlantic Forest: conservation insights

Restoration Ecology, EarlyView.
Abstract Introduction Forest fragmentation and defaunation are major drivers of biodiversity loss in the Atlantic Forest of Brazil, where 70–90% of tree species depend on animal‐mediated seed dispersal. Reintroduction of large frugivores, such as cracids, is being used to restore species populations and lost ecological functions.

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

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...
