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 ...

Unusual echolocation behaviour of the common sword-nosed bat Lonchorhina aurita: an adaptation to aerial insectivory in a phyllostomid bat? [PDF]

open access: yesRoyal Society Open Science, 2019
Most insectivorous bat species in the Neotropical family Phyllostomidae glean insects from ground, water or vegetation surfaces. They use similar and stereotypical echolocation calls that are generally very short (less than 1–3 ms), multi-harmonic and ...

Sensory Ecology of Ostariophysan Alarm Substances

open access: yesJournal of Fish Biology, 2018
Chemical communication of predation risk has evolved multiple times in fish species, with the conspecific alarm substance (CAS) contemporaneously being the most well understood mechanism. CAS is released after epithelial damage, usually when prey fish is captured by a predator, and elicits neurobehavioral adjustments in conspecifics which increase the ...

Understanding Sensory Ecology

open access: yesThe American Biology Teacher, 2016
As visual creatures, humans sometimes have difficulty understanding how other organisms encounter their environments through nonvisual means. Many organisms rely predominantly or exclusively on senses other than sight, including olfaction, chemoreception, and thermoreception.

Anthropogenic noise events perturb acoustic communication networks

open access: yesFrontiers in Ecology and Evolution, 2023
Anthropogenic noise sources impact ecological processes by altering wildlife behavior and interactions with cascading impacts on community structure.

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”).

Sensory ecology of disease vectors

open access: yes, 2022
How do arthropods that transmit human pathogens perceive their world? The answer is essential for controlling the spread of vector-borne diseases in a rational way, and can help solve a major problem in current times. This state-of-the-art compendium, written for students and researchers in the Life Sciences, shows how these organisms use their sensory

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 ...

Hearing abilities and acoustic signalization of the bottlenose dolphin Tursiops Truncatus with early hearing loss

open access: yesFrontiers in Marine Science
Common bottlenose dolphins (Tursiops truncatus) are among non-human mammals that possess the ability for vocal production learning, which strongly depends on learning from conspecifics. The hearing sensitivity and acoustic signals of a 4-year-old captive-

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 ...
