Untangling Sampling Bias From Lemur Dietary Specialization. [PDF]

Ecol Evol
Sampling bias may mediate the estimated effects of functional traits on lemur dietary richness. Considering sampling bias and its effects on functional traits is critical for understanding the ecological roles of species in their environments and the mechanisms underlying trophic interactions.

A Machine Learning Application to Camera-Traps: Robust Species Interactions Datasets for Analysis of Mutualistic Networks. [PDF]

Ecol Evol
Our study includes novel components, focusing on plant‐animal interaction data as study case. We provide comprehensive guidelines and a proven methodology, aligned with existing camera trap standards, for the creation of reliable datasets, as well as a detailed discussion of limitations and logistic challenges. Beyond presenting AI performance metrics,

In a Neotropical Periurban Park, Fruit Consumption by Birds Seems to Be a Random Process

Frontiers in Ecology and Evolution, 2021
Frugivory interactions between birds and fruit-bearing plants are shaped by the abundance of its interacting species, their temporal overlap, the matching of their morphologies, as well as fruit and seed characteristics.

Frugivory in Raptors: New Observations from Australia and a Global Review

Birds, 2021
The diets of raptors are some of the best studied and well-known of all bird groups. Raptors are typically carnivores, hunting and feeding on vertebrates and, for some species, invertebrates. Here, we described instances of the Black Kite (Milvus migrans)

Frugivory underpins the nitrogen cycle [PDF]

Functional Ecology, 2020
Abstract Tropical rainforests are populated by large frugivores that feed upon fruit‐producing woody species, yet their role in regulating the cycle of globally important biogeochemical elements such as nitrogen is still unknown. This is particularly relevant because tropical forests play a prominent role in the nitrogen cycle and are becoming ...

The ecological footprint of Acca sellowiana domestication maintains the residual vertebrate diversity in threatened highlands of Atlantic Forest. [PDF]

PLoS ONE, 2018
Past and contemporary human actions are causing numerous changes in patterns and processes at various ecosystem scales and trophic levels, including unintended downstream changes, such as species interactions. In its native range Acca sellowiana (Feijoa)

An edible fruit from the Jurassic of China

China Geology, 2020
: Frugivory is an important ecological tie between animals and angiosperms. It plays an important role in the evolution of food webs and energy flow networks in the ecosystem. However, little is known about how old this relationship can be due to lack of

Scat piling and strong frugivory of the Balearic lizard, Podarcis lilfordi (Günther, 1874)

BMC Zoology, 2022
Background In lacertid lizards from Mediterranean islands, frugivory is common, particularly under prey scarcity, a characteristic of small islands. In several populations, the diet of the Balearic lizard, Podarcis lilfordi, is extremely variable and ...

Rates of agonism among female primates: a cross-taxon perspective [PDF]

, 2013
Agonism is common in group-living animals, shaping dominance relationships and ultimately impacting individual tness. Rates of agonism vary considerably among taxa, however, and explaining this variation has been central in ecological models of female ...
