摘要

了解入侵物种的资源利用情况有助于预测和减轻其对生物多样性的影响。我们通过描述和比较南非东开普省阿多大象国家公园(AMC)和大鱼河自然保护区(GFRNR)这两个半干旱、受入侵地点的疣猪种群的饮食,探索了入侵普通疣猪饮食的可预测性。这两个地点都以亚热带灌丛生物群落为主,但植被类型不同。我们利用饲料的可用性来估算疣猪在AMC的饮食偏好。我们预测,疣猪会食用入侵地貌中的草。此外,我们还预测一个受入侵地点的疣猪食性将预测另一个受入侵地点的疣猪食性。正如预测的那样,疣猪在两个地点都主要吃草(AMC - 87.4%,GFRNR - 88.5%),很少吃木本植物、肉质植物和草本植物。在AMC,疣猪吃得最多的物种是Cynodon dactylon,而在GFRNR,则是Eragrostis curvula和Cymbopogon pospichilii。我们预测不同地点之间食性的能力受到了消耗植物物种差异的限制。我们发现,疣猪在北极圈保护区的偏好植物物种消耗量与在全球疣猪保护区的消耗量之间存在密切关系。我们的研究表明,疣猪在其原生地之外是一种专门的食草动物,因此会对入侵地区的草群落产生影响,尤其是其偏好的草种。因此,保护管理人员需要对疣猪入侵地区的草类进行监测,以便更好地发现和管理疣猪的影响。

Understanding resource use of an invasive species: Diet of the common warthog in Eastern Cape succulent thicket

Understanding resource use of invasive species provides insights for predicting and mitigating their impacts on biodiversity. We explored the predictability of diet of the invasive common warthog by describing and comparing the diet of warthog populations from two semi-arid, invaded sites, Addo Elephant National Park (AMC), and Great Fish River Nature Reserve (GFRNR), Eastern Cape, South Africa. These sites are both dominated by the Subtropical Thicket biome, but differ in vegetation type. We used forage availability to estimate diet preferences at AMC. We predicted that warthog would consume grass in invaded landscapes. Additionally, we predicted that the diet at one invaded site would predict this at another invaded site. As predicted, warthog mainly consumed grass at both sites (AMC – 87.4%, GFRNR – 88.5%), eating few woody plants, succulents, and forbs. Cynodon dactylon was the most consumed species in AMC, in GFRNR this was Eragrostis curvula and Cymbopogon pospichilii. Our ability to predict the diet between sites was constrained by variation in the plant species consumed. We found strong relationships between the consumption of preferred plant species at AMC and their consumption at GFRNR. We show that warthogs are specialised grazers outside their native range and thus can be expected to impact grass communities in invaded areas, especially preferred grass species. Thus, conservation managers need to monitor grasses in areas invaded by warthog to better detect and manage their impacts.

期刊介绍: The Journal of Arid Environments is an international journal publishing original scientific and technical research articles on physical, biological and cultural aspects of arid, semi-arid, and desert environments. As a forum of multi-disciplinary and interdisciplinary dialogue it addresses research on all aspects of arid environments and their past, present and future use.
