Chemosensory Exploitation and Predator-Prey Arms Races

open access: yesFrontiers in Ecology and Evolution, 2021
Thousands of armed predatory species, distributed widely across the metazoan tree-of-life, consume only hard-shell or exoskeleton-bearing organisms (called “durophagy”).

Functional evolution of Lepidoptera olfactory receptors revealed by deorphanization of a moth repertoire

open access: yesNature Communications, 2017
The range of odours that an insect can detect depends on its olfactory receptors. Here, the authors functionally characterize the olfactory receptor repertoire of the mothSpodoptera littoralis using the Drosophilaempty neuron system and reconstruct the ...

Melanism and color saturation of butterfly assemblages: A comparison between a tropical rainforest and a xeric white forest

open access: yesFrontiers in Ecology and Evolution, 2023
The study of butterfly coloration has helped to identify the ecological pressures involved in the evolution of animal coloration. However, almost all studies that addressed this issue have focused on species that inhabit more temperate environments ...

Functional differences in echolocation call design in an adaptive radiation of bats

open access: yesEcology and Evolution, 2021
All organisms have specialized systems to sense their environment. Most bat species use echolocation for navigation and foraging, but which and how ecological factors shaped echolocation call diversity remains unclear for the most diverse clades ...

Influence of Environmental Factors on Prey Discrimination of Bait-Attracted White Sharks from Gansbaai, South Africa

open access: yesAnimals, 2022
The influence of environmental factors on prey discrimination of bait-attracted white sharks was studied over a six-year period (2008–2013) at Dyer Island Nature Reserve (Gansbaai, South Africa).

The Mormyrid Optic Tectum Is a Topographic Interface for Active Electrolocation and Visual Sensing

open access: yesFrontiers in Neuroanatomy, 2018
The African weakly electric fish Gnathonemus petersii is capable of cross-modal object recognition using its electric sense or vision. Thus, object features stored in the brain are accessible by multiple senses, either through connections between ...

The forgotten pollinators – First field evidence for nectar-feeding by primarily insectivorous elephant-shrews

open access: yesJournal of Pollination Ecology, 2015
Pollination of plants by non-flying mammals, such as mice (Rodentia), is a rarely observed phenomenon. Previously, elephant-shrews (Macroscelidea), small African mammals looking similar to mice, but not being related to them, were believed to be purely ...

Vegetation and vantage point influence visibility across diverse ecosystems: Implications for animal ecology

open access: yesFrontiers in Ecology and Evolution, 2022
Visual information can influence animal behavior and habitat use in diverse ways. Visibility is the property that relates 3D habitat structure to accessibility of visual information.

The adaptive significance of sensory bias in a foraging context: floral colour preferences in the bumblebee Bombus terrestris [PDF]

open access: yes, 2007
Innate sensory biases could play an important role in helping naïve animals to find food. As inexperienced bees are known to have strong innate colour biases we investigated whether bumblebee (Bombus terrestris) colonies with stronger biases for the most
