This study investigates the feeding behavior of the European brown hare on Pianosa Island, Italy, focusing on seasonal dietary preferences in coastal and inland areas. We quantified plant species frequencies in vegetation and fecal pellets, assessed α and β diversity, compared diets via Bray-Curtis matrices, and evaluated selection preferences using the Resource Selection Ratio. During spring, the coastal diet was predominantly composed of grasses, particularly , while non-leguminous forbs like were prominent inland. Fabaceae, including , were highly preferred. In autumn, non-leguminous forbs, such as , were favored on the coast, while grasses like dominated inland. Fabaceae, particularly species, remained a key component of the diet. Plant diversity peaked in spring and decreased markedly in autumn. Dietary overlap between seasons was moderate, with higher similarity observed in the coastal area. The study underscores the importance of Fabaceae and seasonal vegetation changes in shaping the hare's diet. These findings provide valuable insights for conservation, emphasizing the need to preserve key plant species and habitats to support isolated hare populations in Mediterranean ecosystems.
本研究调查了意大利皮亚诺萨岛欧洲棕兔的觅食行为,重点关注沿海和内陆地区的季节性饮食偏好。我们对植被和粪便颗粒中的植物物种频率进行了量化,评估了α和β多样性,通过布雷-柯蒂斯矩阵比较了饮食,并使用资源选择比评估了选择偏好。在春季,沿海地区的饮食主要由草类组成,特别是 ,而在内陆地区,像 这样的非豆科杂草较为突出。豆科植物,包括 ,受到高度青睐。在秋季,沿海地区偏爱像 这样的非豆科杂草,而在内陆地区,像 这样的草类占主导地位。豆科植物,特别是 物种,仍然是饮食的关键组成部分。植物多样性在春季达到峰值,在秋季显著下降。不同季节之间的饮食重叠程度适中,沿海地区的相似性更高。该研究强调了豆科植物和季节性植被变化对塑造野兔饮食的重要性。这些发现为保护工作提供了宝贵的见解,强调了保护关键植物物种和栖息地以支持地中海生态系统中孤立野兔种群的必要性。
