Foraging Behavior of Zonotrichia capensis (Passeriformes: Emberizidae) and Patch Value in Young Live Fences in the Bogotá High Plateau

Acta Biológica Colombiana, 2016
The Rufous-collared Sparrow Zonotrichia capensis is a widely distributed species in neotropical America, it is tolerant to human interventions, but we know little about its foraging ecology on the Colombian Andes.

Tuning movement for sensing in an uncertain world

eLife, 2020
While animals track or search for targets, sensory organs make small unexplained movements on top of the primary task-related motions. While multiple theories for these movements exist—in that they support infotaxis, gain adaptation, spectral whitening ...

Understanding the evolution of nutritive taste in animals: Insights from biological stoichiometry and nutritional geometry

Ecology and Evolution, 2021
A major conceptual gap in taste biology is the lack of a general framework for understanding the evolution of different taste modalities among animal species.

Contrasting Foraging Patterns: Testing Resource-Concentration and Dilution Effects with Pollinators and Seed Predators

Insects, 2016
Resource concentration effects occur when high resource density patches attract and support more foragers than low density patches. In contrast, resource dilution effects can occur if high density patches support fewer consumers.

Prey body size mediates the predation risk associated with being "odd" [PDF]

, 2014
Despite selection pressures on prey animals to maintain phenotypically homogeneous groups, variation in phenotype within animal groups is commonly observed.

Trail complexity and foraged plants for the leaf-cutting ant Atta sexdens (Hymenoptera: Formicidae) in a caatinga area of Bahia

Zoologia (Curitiba)
Leaf-cutting ants (LCAs; Atta, Acromyrmex, and Amoimyrmex) are key herbivores in Neotropical ecosystems, preferentially harvesting leaves from palatable plant species such as pioneers and colonizers.

Pulsed resource availability changes dietary niche breadth and partitioning between generalist rodent consumers

Ecology and Evolution, 2019
Identifying the mechanisms that structure niche breadth and overlap between species is important for determining how species interact and assessing their functional role in an ecosystem.
