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.

Zambian Mole-Rats: 33 Years on the Scene and What We Still Do Not Know and How We Could Learn It

open access: yesFrontiers in Ecology and Evolution, 2022
This article surveys more than three decades of research on Zambian mole-rats (genus Fukomys, Bathyergidae), pointing out some unanswered questions and untested hypotheses and suggesting approaches to address them.

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-

Response to visual and mechano-acoustic predator cues is robust to ocean warming and acidification and is highly variable in European sea bass

open access: yesFrontiers in Marine Science, 2023
Predator-prey interactions and, especially, the success of anti-predator responses are modulated by the sensory channels of vision, olfaction, audition and mechanosensation.

The Sensory and Cognitive Ecology of Nectar Robbing

open access: yesFrontiers in Ecology and Evolution, 2021
Animals foraging from flowers must assess their environment and make critical decisions about which patches, plants, and flowers to exploit to obtain limiting resources. The cognitive ecology of plant-pollinator interactions explores not only the complex

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Complementary shifts in photoreceptor spectral tuning unlock the full adaptive potential of ultraviolet vision in birds

open access: yeseLife, 2016
Color vision in birds is mediated by four types of cone photoreceptors whose maximal sensitivities (λmax) are evenly spaced across the light spectrum.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Stimulus duration encoding occurs early in the moth olfactory pathway

open access: yesCommunications Biology
Pheromones convey rich ethological information and guide insects’ search behavior. Insects navigating in turbulent environments are tasked with the challenge of coding the temporal structure of an odor plume, obliging recognition of the onset and offset ...

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 ...
