Animal Behavior: Fly Flight Moves Forward [PDF]

open access: yesCurrent Biology, 2013
A new study has resolved the paradox of how flies maintain reflexive aversion to your approaching swatter, whilst tolerating similar visual signals during normal forward flight.

Feather moult and bird appearance are correlated with global warming over the last 200 years

open access: yesNature Communications, 2019
Most passerine bird species replace part of their plumage within the first year of life. Here, using data from 4,012 individuals of 19 species, Kiat et al.

Bottlenose Dolphins and Antillean Manatees Respond to Small Multi-Rotor Unmanned Aerial Systems

open access: yesFrontiers in Marine Science, 2018
Unmanned aerial systems (UASs) are powerful tools for research and monitoring of wildlife. However, the effects of these systems on most marine mammals are largely unknown, preventing the establishment of guidelines that will minimize animal disturbance.

Determination of optimal flight altitude to minimise acoustic drone disturbance to wildlife using species audiograms

open access: yesMethods in Ecology and Evolution, 2021
Unmanned aerial vehicles (UAVs) are increasingly important in wildlife data collection but concern over wildlife disturbance has led several countries to ban their use in National Parks.

Digital particle image velocimetry measurements of the downwash distribution of a desert locust Schistocerca gregaria [PDF]

open access: yes, 2006
Actuator disc models of insect flight are concerned solely with the rate of momentum transfer to the air that passes through the disc. These simple models assume that an even pressure is applied across the disc, resulting in a uniform downwash ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Intermittent Gliding in the Hunting Flight of the Kestrel, Falco tinnunculus L. [PDF]

open access: yes, 1983
The hunting flight of the kestrel (Falco tinnunculus) consists of short bouts of flight at wind speed against the wind with the eyes in a fixed position relative to the ground, and of short flights from one such position to the next.
