Growing up with chronic traffic noise exposure leads to transient but not long-term noise tolerance in a songbird

Biology Letters, Journal Year: 2025, Volume and Issue: 21(1)

Noise pollution is on the rise worldwide. An unresolved issue regarding mitigation of noise whether and at which timescales animals may adapt to pollution. Here, we tested continuous highway exposure perinatally during juvenile development increased tolerance in a songbird, zebra finch ( Taeniopygia castanotis ). Breeding pairs were exposed recordings from pre-egg-laying until their offspring reached subadulthood. Subsequently, for both as subadults adults spatial preference test, where birds could choose enter aviaries with different levels noise. Unlike control that preferentially chose quiet aviaries, noise-reared exhibited no preferences first test. However, when experimental retested after two months without exposure, they now avoided previously tolerated preferred quieter aviary. The observed directly release treatment was thus only transient. Growing up chronic did not increase subjects’ tolerance, meaning least this songbird species, adaptation unlikely arise developmental time scale.

Development of an Alternative Design for Single Slope Concrete Barriers to Reduce Working Width

Journal of Road Safety, Journal Year: 2025, Volume and Issue: 36(1)

Published: Feb. 6, 2025

In the most recent 2020 edition of Austroads Guide to Road Design Part 6, important amendments were made required working width values for public domain extruded concrete road safety barriers. These changes deviated from narrower widths that some Australian states, particularly Queensland, had adhered decades. During transition, many completed designs followed previous standards barrier width, raising concerns among asset owners about whether residual risk is acceptable – especially when shields bridge piers or other critical roadside structures. The catastrophic collapse could result in serious injury even fatality users. To address this challenge, two extrapolation methods developed based on only available crash testing a single slope barrier. retain profile commonly used Queensland but achieve reduced by increasing height. Practitioners would benefit evidence-based approach existing designed cross-section constrained and structure at impact. relevant design guidance considerations have been discussed establish conditions use. outcome study has summarised technical note published Department Transport Main Roads practitioners consider under Exception.

The current attention and traction of fauna-sensitive road design in Australian transport research: a systematic review

Australasian Journal of Environmental Management, Journal Year: 2024, Volume and Issue: 31(3), P. 296 - 309

Published: July 2, 2024

The implementation of fauna-sensitive road design has the potential to mitigate negative impacts on wildlife caused by roads. However, our previous international review found adoption been limited at level transport planning, even in nations that mandate this. In Australia, where is still its early stages, a 57 peer-reviewed papers revealed practitioners generally have not acknowledged or considered measures ecology concepts. This lack consideration due deeply rooted economic interests and attitudes institutionalised within industry. While development possible Australian sector, substantial institutional change driven appropriate policies user experiences necessary. We recommend future studies explore practitioner experience better understand conditions facilitated voluntary two states.

Planning for fauna-sensitive road design: A review

Frontiers in Environmental Science, Journal Year: 2022, Volume and Issue: 10

Roads can have significant negative impacts on wildlife. Fauna-sensitive road design (FSRD) alleviate adverse several species by installing specialised structures, such as wildlife crossing structures. This developing subfield has generally, however, had a limited impact transportation planning and management. Indeed, most research is focused narrowly technological solutions, instead of broader policy learnings. systematic quantitative literature review (SQLR) international sought to identify the biodiversity concerns acknowledged in transport policy, well barriers adoption environmental policies within planning. Despite considerable available roads elsewhere, acknowledgement consideration both fauna movement fauna-sensitive were research. More broadly, failure achieve objectives occurred primarily result competing sector interests (conflicted knowledge), different political (political interest), incorrect interpretation policies. In essence, results add new layers understanding field particular, gaps movements limitations current considered. Importantly, identified multiple ecological support tools policy- decision-makers. Integration these projects could facilitate enhanced uptake FSRD measures thus foster improved sustainability network.

Anthropogenic landscape features affect the ground habitat use of Penelope superciliaris (Cracidae), a large seed disperser bird in southeastern Brazil

Abstract The expansion of agriculture and forest plantations over tropical biomes has caused significant species loss, while others persist in remnant native areas anthropogenic lands. Penelope superciliaris , a large seed disperser bird, inhabits human‐modified landscapes; however, its habitat use is poorly known. We investigated how land covers, distance to water sources, landscape features affect the species' ground disturbed undisturbed three landscapes Southeastern Brazil. expected more near sources because higher quality. collected presence‐absence data during two dry seasons at 205 sampling stations with camera traps. Using occupancy models, we calculated cumulative AICc weights covariates for (interpreted as probability use, Ψ) detection frequency p ) parameters. proportion managed forests negatively influenced use. was when trap were located on unpaved roads. Model averaged prediction showed that uses about 56% landscapes. Our results suggest intensively are not favorable or attractive habitats species.
