Time‐stressed Bar‐tailed Godwits exploit novel prey during migratory fuelling

Ibis, EarlyView.
Long‐distance migratory birds breeding in the Arctic face challenges as earlier snowmelt shifts the timing of vital resources. To keep up with these advancements, birds will need to modify their migration. Higher fuelling rates during stopover have been identified as a critical mechanism for accelerating migration, but this requires adequate food ...

Pollinator dependence and pollination deficit in Hedera helix, and effects on frugivore feeding choices

Journal of Pollination Ecology
English ivy (Hedera helix) is an important resource for wildlife in rural and urban ecosystems. It provides pollen and nectar for flower-visiting insects during autumn and fruits for frugivores during winter and spring.

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 ...

Macroevolutionary imprints on the assembly of frugivory networks

, 2019
Biological interactions are a key aspect of ecological communities. Currentinteraction network structures are snapshots of dynamic processes ofcommunity assembly. Thus, assessing the temporal dynamics of ecologicalnetworks or the deep time mechanisms related to the assembly of thosenetworks are key to better understand biodiversity changes in broader ...

Frugivory in Lacistema hasslerianum Chodat (Lacistemaceae), a gallery forest understory treelet in Central Brazil

Brazilian Journal of Biology
The objectives of this study were to know and to characterize the behavioural patterns of frugivorous birds in Lacistema hasslerianum. The study was carried out in the Panga Ecological Station (Uberlândia, Minas Gerais State).

Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

The Anatomical Record, Volume 309, Issue 9, Page 2346-2367, September 2026.
We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

Secondary metabolites of vertebrate-dispersed fruits: evidence for adaptive functions Metabolitos secundarios de frutos dispersados por aves: evidencia de funciones adaptativas

Revista Chilena de Historia Natural, 2000
In this paper, I discuss recent evidence concerning the adaptive significance of secondary metabolites in ripe fleshy fruits, and implications for seed dispersal by birds and other vertebrates.

Frugivory and Seed Dispersal of the Threatened Cactus Browningia candelaris in the Vicinity of a Mining Site in the Atacama Desert, Chile

Diversity
Mining is an indispensable activity that threatens biodiversity globally. However, assessments of key ecological processes for the maintenance of plants threatened by mining, such as the effectiveness of frugivory and seed dispersal, are almost non ...

Connecting Resource Tracking by Frugivores to Temporal Variation in Seed Dispersal Networks

Frontiers in Ecology and Evolution, 2017
Mutualistic interactions between species are crucial for the maintenance and functioning of the community. Current research has shown the importance of not only understanding the structure of these mutualistic interaction networks but also their temporal

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

Journal of Anatomy, Volume 249, Issue 3, Page 544-564, September 2026.
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,
