# The effect of temperature on asexual reproduction in Hydra vulgaris

## TL;DR

This study shows that higher temperatures increase asexual reproduction and population growth in Hydra vulgaris.

## Contribution

The novel finding is that increased temperature enhances asexual budding rates and population growth in Hydra vulgaris.

## Key findings

- Hydra vulgaris populations grow faster at 25°C compared to 15°C.
- Higher temperatures lead to increased budding rates and more buds per polyp.
- Asexual reproduction is more active under warmer conditions.

## Abstract

Hydra vulgaris
is a model cnidarian used for interdisciplinary studies in biology, yet its reproductive responses to environmental changes remain underexplored. This study examined how temperature affects asexual reproduction (budding) rates and population growth in
H. vulgaris
. We placed
Hydra
in two thermal environments, 15°C and 25°C, to compare differences in population growth, number of budding polyps, number of buds, and budding rates under ‘cold’ and ‘hot’ conditions. Our findings indicate that
Hydra
populations exhibit increased growth through asexual budding at higher temperatures.
