Abstract

<p><i>Hydra vulgaris</i> 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 <i>H. vulgaris</i>. We placed <i>Hydra</i> 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 <i>Hydra</i> populations exhibit increased growth through asexual budding at higher temperatures.</p>
