The "Song of a Łódź Pond" – What Do Amphibians Say and What Can We Learn About the City From Them?

In spring and early summer, Łódź's urban ponds, backwaters and small bodies of water are filled with sounds that go almost unnoticed by many residents. Yet, this is precisely when the most intense period of amphibian activity begins – the time of mating, communication and the fight for survival. Jarosław Brodecki discusses the sounds of Łódź ponds and the secrets behind their nocturnal "song" in his lecture "The Song of a Łódź Pond".

Sound as the language of amphibians

During this lecture, Jarosław Brodecki introduces listeners to the world of amphibians found in Łódź and the surrounding area. He discusses both well-known species and less obvious ones, rarely seen but recognisable by their distinctive calls. Sound plays a crucial role in their lives – it allows them to attract mates, signal presence and function in environments where visual contact can be limited.

The speaker demonstrates that the nocturnal concert of amphibians is not a random noise but a precise communication system, dependent on the season, temperature, humidity and structure of the water body.

Amphibians in the city – life in harsh conditions

A reflection on how the urban environment affects amphibians is a crucial part of the lecture. Noise, artificial lighting, intense traffic, changing water levels and the disappearance of natural habitats force these animals to constantly adapt to conditions not originally designed for them.

Jarosław Brodecki points out that amphibians are exceptionally sensitive indicators of the state of the environment. Their presence – or sudden disappearance – reveals much about water quality, the health of ecosystems and the effects of human activity in urban spaces.

Listening attentively to the city

"The Song of Łódź Pond" is also an invitation to shift perspective and listen more carefully to the city, especially after dark and away from main thoroughfares. The lecture demonstrates that nature is not separate from everyday urban life, but rather exists right alongside us – often unnoticed, yet incredibly active. It's a story that encourages us to stop and listen to sounds that are usually lost in the background of everyday hustle and bustle.

Lecture available online

The recording of Jarosław Brodecki's lecture is recommended for those interested in biology and environmental protection, as well as for anyone who wants to better understand the lives of animals in urban areas. It's a story about urban nature, which, though quiet and unassuming, has much to tell those who are willing to listen.

Jarosław Brodecki is a student at the Faculty of Biology and Environmental Protection, 91ɫ, and a recipient of a scholarship from the Ministry of Science and Higher Education in the field of biological sciences. He is an author of award-winning research projects (including first prize in the EU Young Scientists' Competition), focusing on monitoring water bodies, protecting amphibians in Lodz (Łódź-wide Żabing), and researching aquatic pollution. He was a finalist in the "25 under 25" competition by Forbes magazine and McKinsey & Company.
